+# Purell
+
+Purell is a tiny Go library to normalize URLs. It returns a pure URL. Pure-ell. Sanitizer and all. Yeah, I know...
+
+Based on the [wikipedia paper][wiki] and the [RFC 3986 document][rfc].
+
+[](http://travis-ci.org/PuerkitoBio/purell)
+
+## Install
+
+`go get github.com/PuerkitoBio/purell`
+
+## Changelog
+
+* **v1.1.1** : Fix failing test due to Go1.12 changes (thanks to @ianlancetaylor).
+* **2016-11-14 (v1.1.0)** : IDN: Conform to RFC 5895: Fold character width (thanks to @beeker1121).
+* **2016-07-27 (v1.0.0)** : Normalize IDN to ASCII (thanks to @zenovich).
+* **2015-02-08** : Add fix for relative paths issue ([PR #5][pr5]) and add fix for unnecessary encoding of reserved characters ([see issue #7][iss7]).
+* **v0.2.0** : Add benchmarks, Attempt IDN support.
+* **v0.1.0** : Initial release.
+
+## Examples
+
+From `example_test.go` (note that in your code, you would import "github.com/PuerkitoBio/purell", and would prefix references to its methods and constants with "purell."):
+
+```go
+package purell
+
+import (
+ "fmt"
+ "net/url"
+)
+
+func ExampleNormalizeURLString() {
+ if normalized, err := NormalizeURLString("hTTp://someWEBsite.com:80/Amazing%3f/url/",
+ FlagLowercaseScheme|FlagLowercaseHost|FlagUppercaseEscapes); err != nil {
+ panic(err)
+ } else {
+ fmt.Print(normalized)
+ }
+ // Output: http://somewebsite.com:80/Amazing%3F/url/
+}
+
+func ExampleMustNormalizeURLString() {
+ normalized := MustNormalizeURLString("hTTpS://someWEBsite.com:443/Amazing%fa/url/",
+ FlagsUnsafeGreedy)
+ fmt.Print(normalized)
+
+ // Output: http://somewebsite.com/Amazing%FA/url
+}
+
+func ExampleNormalizeURL() {
+ if u, err := url.Parse("Http://SomeUrl.com:8080/a/b/.././c///g?c=3&a=1&b=9&c=0#target"); err != nil {
+ panic(err)
+ } else {
+ normalized := NormalizeURL(u, FlagsUsuallySafeGreedy|FlagRemoveDuplicateSlashes|FlagRemoveFragment)
+ fmt.Print(normalized)
+ }
+
+ // Output: http://someurl.com:8080/a/c/g?c=3&a=1&b=9&c=0
+}
+```
+
+## API
+
+As seen in the examples above, purell offers three methods, `NormalizeURLString(string, NormalizationFlags) (string, error)`, `MustNormalizeURLString(string, NormalizationFlags) (string)` and `NormalizeURL(*url.URL, NormalizationFlags) (string)`. They all normalize the provided URL based on the specified flags. Here are the available flags:
+
+```go
+const (
+ // Safe normalizations
+ FlagLowercaseScheme NormalizationFlags = 1 << iota // HTTP://host -> http://host, applied by default in Go1.1
+ FlagLowercaseHost // http://HOST -> http://host
+ FlagUppercaseEscapes // http://host/t%ef -> http://host/t%EF
+ FlagDecodeUnnecessaryEscapes // http://host/t%41 -> http://host/tA
+ FlagEncodeNecessaryEscapes // http://host/!"#$ -> http://host/%21%22#$
+ FlagRemoveDefaultPort // http://host:80 -> http://host
+ FlagRemoveEmptyQuerySeparator // http://host/path? -> http://host/path
+
+ // Usually safe normalizations
+ FlagRemoveTrailingSlash // http://host/path/ -> http://host/path
+ FlagAddTrailingSlash // http://host/path -> http://host/path/ (should choose only one of these add/remove trailing slash flags)
+ FlagRemoveDotSegments // http://host/path/./a/b/../c -> http://host/path/a/c
+
+ // Unsafe normalizations
+ FlagRemoveDirectoryIndex // http://host/path/index.html -> http://host/path/
+ FlagRemoveFragment // http://host/path#fragment -> http://host/path
+ FlagForceHTTP // https://host -> http://host
+ FlagRemoveDuplicateSlashes // http://host/path//a///b -> http://host/path/a/b
+ FlagRemoveWWW // http://www.host/ -> http://host/
+ FlagAddWWW // http://host/ -> http://www.host/ (should choose only one of these add/remove WWW flags)
+ FlagSortQuery // http://host/path?c=3&b=2&a=1&b=1 -> http://host/path?a=1&b=1&b=2&c=3
+
+ // Normalizations not in the wikipedia article, required to cover tests cases
+ // submitted by jehiah
+ FlagDecodeDWORDHost // http://1113982867 -> http://66.102.7.147
+ FlagDecodeOctalHost // http://0102.0146.07.0223 -> http://66.102.7.147
+ FlagDecodeHexHost // http://0x42660793 -> http://66.102.7.147
+ FlagRemoveUnnecessaryHostDots // http://.host../path -> http://host/path
+ FlagRemoveEmptyPortSeparator // http://host:/path -> http://host/path
+
+ // Convenience set of safe normalizations
+ FlagsSafe NormalizationFlags = FlagLowercaseHost | FlagLowercaseScheme | FlagUppercaseEscapes | FlagDecodeUnnecessaryEscapes | FlagEncodeNecessaryEscapes | FlagRemoveDefaultPort | FlagRemoveEmptyQuerySeparator
+
+ // For convenience sets, "greedy" uses the "remove trailing slash" and "remove www. prefix" flags,
+ // while "non-greedy" uses the "add (or keep) the trailing slash" and "add www. prefix".
+
+ // Convenience set of usually safe normalizations (includes FlagsSafe)
+ FlagsUsuallySafeGreedy NormalizationFlags = FlagsSafe | FlagRemoveTrailingSlash | FlagRemoveDotSegments
+ FlagsUsuallySafeNonGreedy NormalizationFlags = FlagsSafe | FlagAddTrailingSlash | FlagRemoveDotSegments
+
+ // Convenience set of unsafe normalizations (includes FlagsUsuallySafe)
+ FlagsUnsafeGreedy NormalizationFlags = FlagsUsuallySafeGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagRemoveWWW | FlagSortQuery
+ FlagsUnsafeNonGreedy NormalizationFlags = FlagsUsuallySafeNonGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagAddWWW | FlagSortQuery
+
+ // Convenience set of all available flags
+ FlagsAllGreedy = FlagsUnsafeGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
+ FlagsAllNonGreedy = FlagsUnsafeNonGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
+)
+```
+
+For convenience, the set of flags `FlagsSafe`, `FlagsUsuallySafe[Greedy|NonGreedy]`, `FlagsUnsafe[Greedy|NonGreedy]` and `FlagsAll[Greedy|NonGreedy]` are provided for the similarly grouped normalizations on [wikipedia's URL normalization page][wiki]. You can add (using the bitwise OR `|` operator) or remove (using the bitwise AND NOT `&^` operator) individual flags from the sets if required, to build your own custom set.
+
+The [full godoc reference is available on gopkgdoc][godoc].
+
+Some things to note:
+
+* `FlagDecodeUnnecessaryEscapes`, `FlagEncodeNecessaryEscapes`, `FlagUppercaseEscapes` and `FlagRemoveEmptyQuerySeparator` are always implicitly set, because internally, the URL string is parsed as an URL object, which automatically decodes unnecessary escapes, uppercases and encodes necessary ones, and removes empty query separators (an unnecessary `?` at the end of the url). So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it.
+
+* The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*):
+ - %24 -> $
+ - %26 -> &
+ - %2B-%3B -> +,-./0123456789:;
+ - %3D -> =
+ - %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ
+ - %5F -> _
+ - %61-%7A -> abcdefghijklmnopqrstuvwxyz
+ - %7E -> ~
+
+
+* When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization).
+
+* The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell.
+
+* The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object.
+
+### Safe vs Usually Safe vs Unsafe
+
+Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between.
+
+Consider the following URL:
+
+`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
+
+Normalizing with the `FlagsSafe` gives:
+
+`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
+
+With the `FlagsUsuallySafeGreedy`:
+
+`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid`
+
+And with `FlagsUnsafeGreedy`:
+
+`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3`
+
+## TODOs
+
+* Add a class/default instance to allow specifying custom directory index names? At the moment, removing directory index removes `(^|/)((?:default|index)\.\w{1,4})$`.

+
+A package of validators and sanitizers for strings, structs and collections. Based on [validator.js](https://github.com/chriso/validator.js).
+
+#### Installation
+Make sure that Go is installed on your computer.
+Type the following command in your terminal:
+
+ go get github.com/asaskevich/govalidator
+
+or you can get specified release of the package with `gopkg.in`:
+
+ go get gopkg.in/asaskevich/govalidator.v4
+
+After it the package is ready to use.
+
+
+#### Import package in your project
+Add following line in your `*.go` file:
+```go
+import "github.com/asaskevich/govalidator"
+```
+If you are unhappy to use long `govalidator`, you can do something like this:
+```go
+import (
+ valid "github.com/asaskevich/govalidator"
+)
+```
+
+#### Activate behavior to require all fields have a validation tag by default
+`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
+
+`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
+
+```go
+import "github.com/asaskevich/govalidator"
+
+func init() {
+ govalidator.SetFieldsRequiredByDefault(true)
+}
+```
+
+Here's some code to explain it:
+```go
+// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
+type exampleStruct struct {
+ Name string ``
+ Email string `valid:"email"`
+}
+
+// this, however, will only fail when Email is empty or an invalid email address:
+type exampleStruct2 struct {
+ Name string `valid:"-"`
+ Email string `valid:"email"`
+}
+
+// lastly, this will only fail when Email is an invalid email address but not when it's empty:
+type exampleStruct2 struct {
+ Name string `valid:"-"`
+ Email string `valid:"email,optional"`
+}
+```
+
+#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
+##### Custom validator function signature
+A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible.
+```go
+import "github.com/asaskevich/govalidator"
+
+// old signature
+func(i interface{}) bool
+
+// new signature
+func(i interface{}, o interface{}) bool
+```
+
+##### Adding a custom validator
+This was changed to prevent data races when accessing custom validators.
+```go
+import "github.com/asaskevich/govalidator"
+
+// before
+govalidator.CustomTypeTagMap["customByteArrayValidator"] = CustomTypeValidator(func(i interface{}, o interface{}) bool {
+ // ...
+})
+
+// after
+govalidator.CustomTypeTagMap.Set("customByteArrayValidator", CustomTypeValidator(func(i interface{}, o interface{}) bool {
+ // ...
+}))
+```

+
+#### Examples
+###### IsURL
+```go
+println(govalidator.IsURL(`http://user@pass:domain.com/path/page`))
+```
+###### ToString
+```go
+type User struct {
+ FirstName string
+ LastName string
+}
+
+str := govalidator.ToString(&User{"John", "Juan"})
+println(str)
+```
+###### Each, Map, Filter, Count for slices
+Each iterates over the slice/array and calls Iterator for every item
+```go
+data := []interface{}{1, 2, 3, 4, 5}
+var fn govalidator.Iterator = func(value interface{}, index int) {
+ println(value.(int))
+}
+govalidator.Each(data, fn)
+```
+```go
+data := []interface{}{1, 2, 3, 4, 5}
+var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
+ return value.(int) * 3
+}
+_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
+```
+```go
+data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
+var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
+ return value.(int)%2 == 0
+}
+_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
+_ = govalidator.Count(data, fn) // result = 5
+```
+###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
+If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
+```go
+govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
+ return str == "duck"
+})
+```
+For completely custom validators (interface-based), see below.
+
+Here is a list of available validators for struct fields (validator - used function):
+```go
+"email": IsEmail,
+"url": IsURL,
+"dialstring": IsDialString,
+"requrl": IsRequestURL,
+"requri": IsRequestURI,
+"alpha": IsAlpha,
+"utfletter": IsUTFLetter,
+"alphanum": IsAlphanumeric,
+"utfletternum": IsUTFLetterNumeric,
+"numeric": IsNumeric,
+"utfnumeric": IsUTFNumeric,
+"utfdigit": IsUTFDigit,
+"hexadecimal": IsHexadecimal,
+"hexcolor": IsHexcolor,
+"rgbcolor": IsRGBcolor,
+"lowercase": IsLowerCase,
+"uppercase": IsUpperCase,
+"int": IsInt,
+"float": IsFloat,
+"null": IsNull,
+"uuid": IsUUID,
+"uuidv3": IsUUIDv3,
+"uuidv4": IsUUIDv4,
+"uuidv5": IsUUIDv5,
+"creditcard": IsCreditCard,
+"isbn10": IsISBN10,
+"isbn13": IsISBN13,
+"json": IsJSON,
+"multibyte": IsMultibyte,
+"ascii": IsASCII,
+"printableascii": IsPrintableASCII,
+"fullwidth": IsFullWidth,
+"halfwidth": IsHalfWidth,
+"variablewidth": IsVariableWidth,
+"base64": IsBase64,
+"datauri": IsDataURI,
+"ip": IsIP,
+"port": IsPort,
+"ipv4": IsIPv4,
+"ipv6": IsIPv6,
+"dns": IsDNSName,
+"host": IsHost,
+"mac": IsMAC,
+"latitude": IsLatitude,
+"longitude": IsLongitude,
+"ssn": IsSSN,
+"semver": IsSemver,
+"rfc3339": IsRFC3339,
+"rfc3339WithoutZone": IsRFC3339WithoutZone,
+"ISO3166Alpha2": IsISO3166Alpha2,
+"ISO3166Alpha3": IsISO3166Alpha3,
+```
+Validators with parameters
+
+```go
+"range(min|max)": Range,
+"length(min|max)": ByteLength,
+"runelength(min|max)": RuneLength,
+"stringlength(min|max)": StringLength,
+"matches(pattern)": StringMatches,
+"in(string1|string2|...|stringN)": IsIn,
+"rsapub(keylength)" : IsRsaPub,
+```
+
+And here is small example of usage:
+```go
+type Post struct {
+ Title string `valid:"alphanum,required"`
+ Message string `valid:"duck,ascii"`
+ Message2 string `valid:"animal(dog)"`
+ AuthorIP string `valid:"ipv4"`
+ Date string `valid:"-"`
+}
+post := &Post{
+ Title: "My Example Post",
+ Message: "duck",
+ Message2: "dog",
+ AuthorIP: "123.234.54.3",
+}
+
+// Add your own struct validation tags
+govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
+ return str == "duck"
+})
+
+// Add your own struct validation tags with parameter
+govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool {
+ species := params[0]
+ return str == species
+})
+govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$")
+
+result, err := govalidator.ValidateStruct(post)
+if err != nil {
+ println("error: " + err.Error())
+}
+println(result)
+```
+###### WhiteList
+```go
+// Remove all characters from string ignoring characters between "a" and "z"
+println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
+```
+
+###### Custom validation functions
+Custom validation using your own domain specific validators is also available - here's an example of how to use it:
+```go
+import "github.com/asaskevich/govalidator"
+
+type CustomByteArray [6]byte // custom types are supported and can be validated
+
+type StructWithCustomByteArray struct {
+ ID CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
+ Email string `valid:"email"`
+ CustomMinLength int `valid:"-"`
+}
+
+govalidator.CustomTypeTagMap.Set("customByteArrayValidator", CustomTypeValidator(func(i interface{}, context interface{}) bool {
+ switch v := context.(type) { // you can type switch on the context interface being validated
+ case StructWithCustomByteArray:
+ // you can check and validate against some other field in the context,
+ // return early or not validate against the context at all – your choice
+ case SomeOtherType:
+ // ...
+ default:
+ // expecting some other type? Throw/panic here or continue
+ }
+
+ switch v := i.(type) { // type switch on the struct field being validated
+ case CustomByteArray:
+ for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
+ if e != 0 {
+ return true
+ }
+ }
+ }
+ return false
+}))
+govalidator.CustomTypeTagMap.Set("customMinLengthValidator", CustomTypeValidator(func(i interface{}, context interface{}) bool {
+ switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
+ case StructWithCustomByteArray:
+ return len(v.ID) >= v.CustomMinLength
+ }
+ return false
+}))
+```
+
+###### Custom error messages
+Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
+```go
+type Ticket struct {
+ Id int64 `json:"id"`
+ FirstName string `json:"firstname" valid:"required~First name is blank"`
+}
+```
+

+# Contributing
+
+## Issues
+
+* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
+* Please indicate the platform you are using fsnotify on.
+* A code example to reproduce the problem is appreciated.
+
+## Pull Requests
+
+### Contributor License Agreement
+
+fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
+
+Please indicate that you have signed the CLA in your pull request.
+
+### How fsnotify is Developed
+
+* Development is done on feature branches.
+* Tests are run on BSD, Linux, macOS and Windows.
+* Pull requests are reviewed and [applied to master][am] using [hub][].
+ * Maintainers may modify or squash commits rather than asking contributors to.
+* To issue a new release, the maintainers will:
+ * Update the CHANGELOG
+ * Tag a version, which will become available through gopkg.in.
+
+### How to Fork
+
+For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
+
+1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
+2. Create your feature branch (`git checkout -b my-new-feature`)
+3. Ensure everything works and the tests pass (see below)
+4. Commit your changes (`git commit -am 'Add some feature'`)
+
+Contribute upstream:
+
+1. Fork fsnotify on GitHub
+2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
+3. Push to the branch (`git push fork my-new-feature`)
+4. Create a new Pull Request on GitHub
+
+This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
+
+### Testing
+
+fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
+
+Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
+
+To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
+
+* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
+* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
+* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
+* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
+* When you're done, you will want to halt or destroy the Vagrant boxes.
+
+Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
+
+Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
+
+### Maintainers
+
+Help maintaining fsnotify is welcome. To be a maintainer:
+
+* Submit a pull request and sign the CLA as above.
+* You must be able to run the test suite on Mac, Windows, Linux and BSD.
+
+To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
+
+All code changes should be internal pull requests.
+
+Releases are tagged using [Semantic Versioning](http://semver.org/).

+# File system notifications for Go
+
+[](https://godoc.org/github.com/fsnotify/fsnotify) [](https://goreportcard.com/report/github.com/fsnotify/fsnotify)
+
+fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
+
+```console
+go get -u golang.org/x/sys/...
+```
+
+Cross platform: Windows, Linux, BSD and macOS.
+
+|Adapter |OS |Status |
+|----------|----------|----------|
+|inotify |Linux 2.6.27 or later, Android\*|Supported [](https://travis-ci.org/fsnotify/fsnotify)|
+|kqueue |BSD, macOS, iOS\*|Supported [](https://travis-ci.org/fsnotify/fsnotify)|
+|ReadDirectoryChangesW|Windows|Supported [](https://ci.appveyor.com/project/NathanYoungman/fsnotify/branch/master)|
+|FSEvents |macOS |[Planned](https://github.com/fsnotify/fsnotify/issues/11)|
+|FEN |Solaris 11 |[In Progress](https://github.com/fsnotify/fsnotify/issues/12)|
+|fanotify |Linux 2.6.37+ | |
+|USN Journals |Windows |[Maybe](https://github.com/fsnotify/fsnotify/issues/53)|
+|Polling |*All* |[Maybe](https://github.com/fsnotify/fsnotify/issues/9)|
+
+\* Android and iOS are untested.
+
+Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) and consult the [FAQ](#faq) for usage information.
+
+## API stability
+
+fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
+
+All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
+
+Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
+
+## Contributing
+
+Please refer to [CONTRIBUTING][] before opening an issue or pull request.

+## Example
+
+See [example_test.go](https://github.com/fsnotify/fsnotify/blob/master/example_test.go).
+
+## FAQ
+
+**When a file is moved to another directory is it still being watched?**
+
+No (it shouldn't be, unless you are watching where it was moved to).
+
+**When I watch a directory, are all subdirectories watched as well?**
+
+No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
+
+**Do I have to watch the Error and Event channels in a separate goroutine?**
+
+As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
+
+**Why am I receiving multiple events for the same file on OS X?**
+
+Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
+
+**How many files can be watched at once?**
+
+There are OS-specific limits as to how many watches can be created:
+* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
+* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a

+ has been advised of the possibility of such damages.

+Package analysis provides methods to work with a Swagger specification document from
+package go-openapi/spec.
+
+Analyzing a specification
+
+An analysed specification object (type Spec) provides methods to work with swagger definition.
+
+Flattening or expanding a specification
+
+Flattening a specification bundles all remote $ref in the main spec document.
+Depending on flattening options, additional preprocessing may take place:
+ - full flattening: replacing all inline complex constructs by a named entry in #/definitions
+ - expand: replace all $ref's in the document by their expanded content
+
+Merging several specifications
+
+Mixin several specifications merges all Swagger constructs, and warns about found conflicts.
+
+Fixing a specification
+
+Unmarshalling a specification with golang json unmarshalling may lead to
+some unwanted result on present but empty fields.
+
+Analyzing a Swagger schema
+
+Swagger schemas are analyzed to determine their complexity and qualify their content.

+// There is a minimal and a full flattening mode.
+//
+// Minimally flattening a spec means:
+// - Expanding parameters, responses, path items, parameter items and header items (references to schemas are left
+// unscathed)
+// - Importing external (http, file) references so they become internal to the document
+// - Moving every JSON pointer to a $ref to a named definition (i.e. the reworked spec does not contain pointers
+// like "$ref": "#/definitions/myObject/allOfs/1")
+//
+// A minimally flattened spec thus guarantees the following properties:
+// - all $refs point to a local definition (i.e. '#/definitions/...')
+// - definitions are unique
+//
+// NOTE: arbitrary JSON pointers (other than $refs to top level definitions) are rewritten as definitions if they
+// represent a complex schema or express commonality in the spec.
+// Otherwise, they are simply expanded.
+//
+// Minimal flattening is necessary and sufficient for codegen rendering using go-swagger.
+//
+// Fully flattening a spec means:
+// - Moving every complex inline schema to be a definition with an auto-generated name in a depth-first fashion.
+//
+// By complex, we mean every JSON object with some properties.
+// Arrays, when they do not define a tuple,
+// or empty objects with or without additionalProperties, are not considered complex and remain inline.
+//
+// NOTE: rewritten schemas get a vendor extension x-go-gen-location so we know from which part of the spec definitions
+// have been created.
+//
+// Available flattening options:
+// - Minimal: stops flattening after minimal $ref processing, leaving schema constructs untouched
+// - Expand: expand all $ref's in the document (inoperant if Minimal set to true)
+// - Verbose: croaks about name conflicts detected
+// - RemoveUnused: removes unused parameters, responses and definitions after expansion/flattening
+//
+// NOTE: expansion removes all $ref save circular $ref, which remain in place
+//
+// TODO: additional options
+// - ProgagateNameExtensions: ensure that created entries properly follow naming rules when their parent have set a
+// x-go-name extension

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a

+a Ruleset is the config of pluralization rules
+you can extend the rules with the Add* methods
+
+func NewDefaultRuleset() *Ruleset
+create a new ruleset and load it with the default
+set of common English pluralization rules
+
+func NewRuleset() *Ruleset
+create a blank ruleset. Unless you are going to
+build your own rules from scratch you probably
+won't need this and can just use the defaultRuleset
+via the global inflect.* methods
+
+func (rs *Ruleset) AddAcronym(word string)
+if you use acronym you may need to add them to the ruleset
+to prevent Underscored words of things like "HTML" coming out
+as "h_t_m_l"
+
+func (rs *Ruleset) AddHuman(suffix, replacement string)
+Human rules are applied by humanize to show more friendly
+versions of words

+
+func (rs *Ruleset) AddSingularExact(suffix, replacement string, exact bool)
+same as AddSingular but you can set `exact` to force
+a full string match
+
+func (rs *Ruleset) AddUncountable(word string)
+add a word to this ruleset that has the same singular and plural form
+for example: "rice"
+
+func (rs *Ruleset) Asciify(word string) string
+transforms latin characters like é -> e
+
+func (rs *Ruleset) Camelize(word string) string
+"dino_party" -> "DinoParty"
+
+func (rs *Ruleset) CamelizeDownFirst(word string) string
+same as Camelcase but with first letter downcased

+uppercase first character
+
+func (rs *Ruleset) Dasherize(word string) string
+"SomeText" -> "some-text"
+
+func (rs *Ruleset) ForeignKey(word string) string
+an underscored foreign key name "Person" -> "person_id"
+
+func (rs *Ruleset) ForeignKeyCondensed(word string) string
+a foreign key (with an underscore) "Person" -> "personid"
+
+func (rs *Ruleset) Humanize(word string) string
+First letter of sentance captitilized
+Uses custom friendly replacements via AddHuman()
+
+func (rs *Ruleset) Ordinalize(str string) string

+
+func (rs *Ruleset) Parameterize(word string) string
+param safe dasherized names like "my-param"
+
+func (rs *Ruleset) ParameterizeJoin(word, sep string) string
+param safe dasherized names with custom seperator
+
+func (rs *Ruleset) Pluralize(word string) string
+returns the plural form of a singular word
+
+func (rs *Ruleset) Singularize(word string) string
+returns the singular form of a plural word
+
+func (rs *Ruleset) Tableize(word string) string
+Rails style pluralized table names: "SuperPerson" -> "super_people"
+
+func (rs *Ruleset) Titleize(word string) string
+Captitilize every word in sentance "hello there" -> "Hello There"
+
+func (rs *Ruleset) Typeify(word string) string
+"something_like_this" -> "SomethingLikeThis"

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+
+ You may add Your own copyright statement to Your modifications and

+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,

+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Denco [](https://travis-ci.org/naoina/denco)
+
+The fast and flexible HTTP request router for [Go](http://golang.org).
+
+Denco is based on Double-Array implementation of [Kocha-urlrouter](https://github.com/naoina/kocha-urlrouter).
+However, Denco is optimized and some features added.
+
+## Features
+
+* Fast (See [go-http-routing-benchmark](https://github.com/naoina/go-http-routing-benchmark))
+* [URL patterns](#url-patterns) (`/foo/:bar` and `/foo/*wildcard`)
+* Small (but enough) URL router API
+* HTTP request multiplexer like `http.ServeMux`
+
+## Installation
+
+ go get -u github.com/go-openapi/runtime/middleware/denco
+
+## Using as HTTP request multiplexer
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+ "net/http"
+
+ "github.com/go-openapi/runtime/middleware/denco"
+)
+
+func Index(w http.ResponseWriter, r *http.Request, params denco.Params) {
+ fmt.Fprintf(w, "Welcome to Denco!\n")
+}
+
+func User(w http.ResponseWriter, r *http.Request, params denco.Params) {
+ fmt.Fprintf(w, "Hello %s!\n", params.Get("name"))
+}
+
+func main() {
+ mux := denco.NewMux()
+ handler, err := mux.Build([]denco.Handler{
+ mux.GET("/", Index),
+ mux.GET("/user/:name", User),
+ mux.POST("/user/:name", User),
+ })
+ if err != nil {
+ panic(err)
+ }
+ log.Fatal(http.ListenAndServe(":8080", handler))
+}
+```
+
+## Using as URL router
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/go-openapi/runtime/middleware/denco"
+)
+
+type route struct {
+ name string
+}
+
+func main() {
+ router := denco.New()
+ router.Build([]denco.Record{
+ {"/", &route{"root"}},
+ {"/user/:id", &route{"user"}},
+ {"/user/:name/:id", &route{"username"}},
+ {"/static/*filepath", &route{"static"}},
+ })
+
+ data, params, found := router.Lookup("/")
+ // print `&main.route{name:"root"}, denco.Params(nil), true`.
+ fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+ data, params, found = router.Lookup("/user/hoge")
+ // print `&main.route{name:"user"}, denco.Params{denco.Param{Name:"id", Value:"hoge"}}, true`.
+ fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+ data, params, found = router.Lookup("/user/hoge/7")
+ // print `&main.route{name:"username"}, denco.Params{denco.Param{Name:"name", Value:"hoge"}, denco.Param{Name:"id", Value:"7"}}, true`.
+ fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+
+ data, params, found = router.Lookup("/static/path/to/file")
+ // print `&main.route{name:"static"}, denco.Params{denco.Param{Name:"filepath", Value:"path/to/file"}}, true`.
+ fmt.Printf("%#v, %#v, %#v\n", data, params, found)
+}
+```
+
+See [Godoc](http://godoc.org/github.com/go-openapi/runtime/middleware/denco) for more details.
+
+## Getting the value of path parameter
+
+You can get the value of path parameter by 2 ways.
+
+1. Using [`denco.Params.Get`](http://godoc.org/github.com/go-openapi/runtime/middleware/denco#Params.Get) method
+2. Find by loop
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/go-openapi/runtime/middleware/denco"
+)
+
+func main() {
+ router := denco.New()
+ if err := router.Build([]denco.Record{
+ {"/user/:name/:id", "route1"},
+ }); err != nil {
+ panic(err)
+ }
+
+ // 1. Using denco.Params.Get method.
+ _, params, _ := router.Lookup("/user/alice/1")
+ name := params.Get("name")
+ if name != "" {
+ fmt.Printf("Hello %s.\n", name) // prints "Hello alice.".
+ }
+
+ // 2. Find by loop.
+ for _, param := range params {
+ if param.Name == "name" {
+ fmt.Printf("Hello %s.\n", name) // prints "Hello alice.".
+ }
+ }
+}
+```
+
+## URL patterns
+
+Denco's route matching strategy is "most nearly matching".
+
+When routes `/:name` and `/alice` have been built, URI `/alice` matches the route `/alice`, not `/:name`.
+Because URI `/alice` is more match with the route `/alice` than `/:name`.
+
+For more example, when routes below have been built:
+
+```
+/user/alice
+/user/:name
+/user/:name/:id
+/user/alice/:id
+/user/:id/bob
+```
+
+Routes matching are:
+
+```
+/user/alice => "/user/alice" (no match with "/user/:name")
+/user/bob => "/user/:name"
+/user/naoina/1 => "/user/:name/1"
+/user/alice/1 => "/user/alice/:id" (no match with "/user/:name/:id")
+/user/1/bob => "/user/:id/bob" (no match with "/user/:name/:id")
+/user/alice/bob => "/user/alice/:id" (no match with "/user/:name/:id" and "/user/:id/bob")
+```
+
+## Limitation
+
+Denco has some limitations below.
+
+* Number of param records (such as `/:name`) must be less than 2^22
+* Number of elements of internal slice must be less than 2^22
+
+## Benchmarks
+
+ cd $GOPATH/github.com/go-openapi/runtime/middleware/denco
+ go test -bench . -benchmem

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+ has been advised of the possibility of such damages.

+// of the operation's URL. This does not include the host or base path of the API. For example, in `/items/{itemId}`,
+// the path parameter is `itemId`.
+// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`.
+// * Header - Custom headers that are expected as part of the request.
+// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be
+// _one_ body parameter. The name of the body parameter has no effect on the parameter itself and is used for
+// documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist
+// together for the same operation.
+// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or
+// `multipart/form-data` are used as the content type of the request (in Swagger's definition,
+// the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used
+// to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be
+// declared together with a body parameter for the same operation. Form parameters have a different format based on
+// the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4).
+// * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload.
+// For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple
+// parameters that are being transferred.
+// * `multipart/form-data` - each parameter takes a section in the payload with an internal header.
+// For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is
+// `submit-name`. This type of form parameters is more commonly used for file transfers.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+
+This package exposes a registry of data types to support string formats in the go-openapi toolkit.
+
+strfmt represents a well known string format such as credit card or email. The go toolkit for OpenAPI specifications knows how to deal with those.
+
+## Supported data formats
+go-openapi/strfmt follows the swagger 2.0 specification with the following formats
+defined [here](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types).
+
+It also provides convenient extensions to go-openapi users.
+
+- [x] JSON-schema draft 4 formats
+ - date-time
+ - email
+ - hostname
+ - ipv4
+ - ipv6
+ - uri
+- [x] swagger 2.0 format extensions
+ - binary
+ - byte (e.g. base64 encoded string)
+ - date (e.g. "1970-01-01")
+ - password
+- [x] go-openapi custom format extensions
+ - bsonobjectid (BSON objectID)
+ - creditcard
+ - duration (e.g. "3 weeks", "1ms")
+ - hexcolor (e.g. "#FFFFFF")
+ - isbn, isbn10, isbn13
+ - mac (e.g "01:02:03:04:05:06")
+ - rgbcolor (e.g. "rgb(100,100,100)")
+ - ssn
+ - uuid, uuid3, uuid4, uuid5
+ - cidr (e.g. "192.0.2.1/24", "2001:db8:a0b:12f0::1/32")
+
+> NOTE: as the name stands for, this package is intended to support string formatting only.
+> It does not provide validation for numerical values with swagger format extension for JSON types "number" or
+> "integer" (e.g. float, double, int32...).
+
+## Format types
+Types defined in strfmt expose marshaling and validation capabilities.
+
+List of defined types:
+- Base64
+- CreditCard
+- Date
+- DateTime
+- Duration
+- Email
+- HexColor
+- Hostname
+- IPv4
+- IPv6
+- CIDR
+- ISBN
+- ISBN10
+- ISBN13
+- MAC
+- ObjectId
+- Password
+- RGBColor
+- SSN
+- URI
+- UUID
+- UUID3
+- UUID4
+- UUID5

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All

+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ivan+abuse@flanders.co.nz. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+Package validate provides methods to validate a swagger specification,
+as well as tools to validate data against their schema.
+
+This package follows Swagger 2.0. specification (aka OpenAPI 2.0). Reference
+can be found here: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md.
+
+Validating a specification
+
+Validates a spec document (from JSON or YAML) against the JSON schema for swagger,
+then checks a number of extra rules that can't be expressed in JSON schema.
+
+Entry points:
+ - Spec()
+ - NewSpecValidator()
+ - SpecValidator.Validate()
+
+Reported as errors:
+ [x] definition can't declare a property that's already defined by one of its ancestors
+ [x] definition's ancestor can't be a descendant of the same model
+ [x] path uniqueness: each api path should be non-verbatim (account for path param names) unique per method
+ [x] each security reference should contain only unique scopes
+ [x] each security scope in a security definition should be unique
+ [x] parameters in path must be unique
+ [x] each path parameter must correspond to a parameter placeholder and vice versa
+ [x] each referenceable definition must have references
+ [x] each definition property listed in the required array must be defined in the properties of the model
+ [x] each parameter should have a unique `name` and `type` combination
+ [x] each operation should have only 1 parameter of type body
+ [x] each reference must point to a valid object
+ [x] every default value that is specified must validate against the schema for that property
+ [x] items property is required for all schemas/definitions of type `array`

+
+Validating a schema
+
+The schema validation toolkit validates data against JSON-schema-draft 04 schema.
+
+It is tested against the full json-schema-testing-suite (https://github.com/json-schema-org/JSON-Schema-Test-Suite),
+except for the optional part (bignum, ECMA regexp, ...).
+
+It supports the complete JSON-schema vocabulary, including keywords not supported by Swagger (e.g. additionalItems, ...)
+
+Entry points:
+ - AgainstSchema()
+ - ...
+
+Known limitations
+
+With the current version of this package, the following aspects of swagger are not yet supported:
+ [ ] errors and warnings are not reported with key/line number in spec
+ [ ] default values and examples on responses only support application/json producer type
+ [ ] invalid numeric constraints (such as Minimum, etc..) are not checked except for default and example values
+ [ ] rules for collectionFormat are not implemented
+ [ ] no validation rule for polymorphism support (discriminator) [not done here]
+ [ ] valid js ECMA regexp not supported by Go regexp engine are considered invalid
+ [ ] arbitrary large numbers are not supported: max is math.MaxFloat64

+# stack
+
+Package stack implements utilities to capture, manipulate, and format call
+stacks. It provides a simpler API than package runtime.
+
+The implementation takes care of the minutia and special cases of interpreting
+the program counter (pc) values returned by runtime.Callers.
+
+## Versioning
+
+Package stack publishes releases via [semver](http://semver.org/) compatible Git
+tags prefixed with a single 'v'. The master branch always contains the latest
+release. The develop branch contains unreleased commits.
+
+## Formatting
+
+Package stack's types implement fmt.Formatter, which provides a simple and
+flexible way to declaratively configure formatting when used with logging or
+error tracking packages.
+
+```go
+func DoTheThing() {
+ c := stack.Caller(0)
+ log.Print(c) // "source.go:10"
+ log.Printf("%+v", c) // "pkg/path/source.go:10"
+ log.Printf("%n", c) // "DoTheThing"
+
+ s := stack.Trace().TrimRuntime()
+ log.Print(s) // "[source.go:15 caller.go:42 main.go:14]"
+}
+```
+
+See the docs for all of the supported formatting options.

+// but not the GOPATH. We can extract the package path from that and append the
+// last segments of the file path to arrive at the desired package qualified
+// file path. For example, given:
+//
+// GOPATH /home/user
+// import path pkg/sub
+// frame.File /home/user/src/pkg/sub/file.go
+// frame.Function pkg/sub.Type.Method
+// Desired return pkg/sub/file.go
+//
+// It appears that we simply need to trim ".Type.Method" from frame.Function and
+// append "/" + path.Base(file).
+//
+// But there are other wrinkles. Although it is idiomatic to do so, the internal
+// name of a package is not required to match the last segment of its import
+// path. In addition, the introduction of modules in Go 1.11 allows working
+// without a GOPATH. So we also must make these work right:
+//
+// GOPATH /home/user
+// import path pkg/go-sub
+// package name sub
+// frame.File /home/user/src/pkg/go-sub/file.go
+// frame.Function pkg/sub.Type.Method
+// Desired return pkg/go-sub/file.go
+//
+// Module path pkg/v2
+// import path pkg/v2/go-sub
+// package name sub
+// frame.File /home/user/cloned-pkg/go-sub/file.go
+// frame.Function pkg/v2/sub.Type.Method
+// Desired return pkg/v2/go-sub/file.go
+//
+// We can handle all of these situations by using the package path extracted
+// from frame.Function up to, but not including, the last segment as the prefix
+// and the last two segments of frame.File as the suffix of the returned path.
+// This preserves the existing behavior when working in a GOPATH without modules

+/*Package generator provides the code generation library for go-swagger.
+
+Generating data types
+
+The general idea is that you should rarely see interface{} in the generated code.
+You get a complete representation of a swagger document in somewhat idiomatic go.
+
+To do so, there is a set of mapping patterns that are applied,
+to map a Swagger specification to go types:
+
+ definition of primitive => type alias/name
+ definition of array => type alias/name
+ definition of map => type alias/name
+
+ definition of object
+ with properties => struct
+ definition of $ref => type alias/name
+
+ object with only
+ additional properties => map[string]T
+
+ object with additional
+ properties and properties => custom serializer
+
+ schema with schema array
+ in items => tuple (struct with properties, custom serializer)
+
+ schema with all of => struct
+
+ * allOf schema with $ref => embedded value
+ * allOf schema with properties => properties are included in struct
+ * adding an allOf schema with just "x-isnullable": true or
+ "x-nullable": true turns the schema into a pointer when
+ there are only other extension properties provided
+
+NOTE: anyOf and oneOf JSON-schema constructs are not supported by Swagger 2.0
+
+A property on a definition is a pointer when any one of the following conditions is met:
+
+ it is an object schema (struct)
+ it has x-nullable or x-isnullable as vendor extension
+ it is a primitive where the zero value is valid but would fail validation
+ otherwise strings minLength > 0 or required results in non-pointer
+ numbers min > 0, max < 0 and min < max
+
+JSONSchema and by extension Swagger allow for items that have a fixed size array,
+with the schema describing the items at each index. This can be combined with additional items
+to form some kind of tuple with varargs.
+
+To map this to go it creates a struct that has fixed names and a custom json serializer.
+
+NOTE: the additionalItems keyword is not supported by Swagger 2.0. However, the generator and validator parts
+in go-swagger do.
+
+
+Documenting the generated code
+
+The code that is generated also gets the doc comments that are used by the scanner
+to generate a spec from go code. So that after generation you should be able to reverse
+generate a spec from the code that was generated by your spec.
+
+It should be equivalent to the original spec but might miss some default values and examples. */

+/*Package scan provides a scanner for go files that produces a swagger spec document.
+
+You give it a main file and it will parse all the files that are required by that main
+package to produce a swagger specification.
+
+To use you can add a go:generate comment to your main file for example:
+
+ //go:generate swagger generate spec
+
+The following annotations exist:
+
+swagger:meta
+
+The swagger:meta annotation flags a file as source for metadata about the API.
+This is typically a doc.go file with your package documentation.
+
+You can specify a Consumes and Produces key which has a new content type on each line
+Schemes is a tag that is required and allows for a comma separated string composed of:
+http, https, ws or wss
+
+Host and BasePath can be specified but those values will be defaults,
+they should get substituted when serving the swagger spec.
+
+Default parameters and responses are not supported at this stage, for those you can edit the template json.
+
+swagger:strfmt [name]
+
+A swagger:strfmt annotation names a type as a string formatter. The name is mandatory and that is
+what will be used as format name for this particular string format.
+String formats should only be used for very well known formats.
+
+swagger:model [?model name]
+
+A swagger:model annotation optionally gets a model name as extra data on the line.
+when this appears anywhere in a comment for a struct, then that struct becomes a schema
+in the definitions object of swagger.
+
+The struct gets analyzed and all the collected models are added to the tree.
+The refs are tracked separately so that they can be renamed later on.
+
+When this annotation is found to be on an interface instead of a struct, the properties are provided
+through exported nullary methods.
+
+A property of an interface model can have a Discriminator: true annotation to mark that field as
+the field that will contain the discriminator value.
+
+swagger:route [method] [path pattern] [operation id] [?tag1 tag2 tag3]
+
+A swagger:route annotation links a path to a method.
+This operation gets a unique id, which is used in various places as method name.
+One such usage is in method names for client generation for example.
+
+Because there are many routers available, this tool does not try to parse the paths
+you provided to your routing library of choice. So you have to specify your path pattern
+yourself in valid swagger syntax.
+
+swagger:params [operationid1 operationid2]
+
+Links a struct to one or more operations. The params in the resulting swagger spec can be composed of several structs.
+There are no guarantees given on how property name overlaps are resolved when several structs apply to the same operation.
+This tag works very similarly to the swagger:model tag except that it produces valid parameter objects instead of schema
+objects.
+
+swagger:response [?response name]
+
+Reads a struct decorated with swagger:response and uses that information to fill up the headers and the schema for a response.
+A swagger:route can specify a response name for a status code and then the matching response will be used for that operation in the swagger definition.

+================
+[](https://godoc.org/github.com/gorilla/handlers)
+[](https://circleci.com/gh/gorilla/handlers)
+[](https://sourcegraph.com/github.com/gorilla/handlers?badge)
+
+
+Package handlers is a collection of handlers (aka "HTTP middleware") for use
+with Go's `net/http` package (or any framework supporting `http.Handler`), including:
+
+* [**LoggingHandler**](https://godoc.org/github.com/gorilla/handlers#LoggingHandler) for logging HTTP requests in the Apache [Common Log
+ Format](http://httpd.apache.org/docs/2.2/logs.html#common).
+* [**CombinedLoggingHandler**](https://godoc.org/github.com/gorilla/handlers#CombinedLoggingHandler) for logging HTTP requests in the Apache [Combined Log
+ Format](http://httpd.apache.org/docs/2.2/logs.html#combined) commonly used by
+ both Apache and nginx.
+* [**CompressHandler**](https://godoc.org/github.com/gorilla/handlers#CompressHandler) for gzipping responses.
+* [**ContentTypeHandler**](https://godoc.org/github.com/gorilla/handlers#ContentTypeHandler) for validating requests against a list of accepted
+ content types.
+* [**MethodHandler**](https://godoc.org/github.com/gorilla/handlers#MethodHandler) for matching HTTP methods against handlers in a
+ `map[string]http.Handler`
+* [**ProxyHeaders**](https://godoc.org/github.com/gorilla/handlers#ProxyHeaders) for populating `r.RemoteAddr` and `r.URL.Scheme` based on the
+ `X-Forwarded-For`, `X-Real-IP`, `X-Forwarded-Proto` and RFC7239 `Forwarded`
+ headers when running a Go server behind a HTTP reverse proxy.
+* [**CanonicalHost**](https://godoc.org/github.com/gorilla/handlers#CanonicalHost) for re-directing to the preferred host when handling multiple
+ domains (i.e. multiple CNAME aliases).
+* [**RecoveryHandler**](https://godoc.org/github.com/gorilla/handlers#RecoveryHandler) for recovering from unexpected panics.
+
+Other handlers are documented [on the Gorilla
+website](https://www.gorillatoolkit.org/pkg/handlers).
+
+## Example
+
+A simple example using `handlers.LoggingHandler` and `handlers.CompressHandler`:
+
+```go
+import (
+ "net/http"
+ "github.com/gorilla/handlers"
+)
+
+func main() {
+ r := http.NewServeMux()
+
+ // Only log requests to our admin dashboard to stdout
+ r.Handle("/admin", handlers.LoggingHandler(os.Stdout, http.HandlerFunc(ShowAdminDashboard)))
+ r.HandleFunc("/", ShowIndex)
+
+ // Wrap our server with our gzip handler to gzip compress all responses.
+ http.ListenAndServe(":8000", handlers.CompressHandler(r))
+}
+```

+
+2.1. Grants
+
+ Each Contributor hereby grants You a world-wide, royalty-free,
+ non-exclusive license:
+
+ a. under intellectual property rights (other than patent or trademark)
+ Licensable by such Contributor to use, reproduce, make available,
+ modify, display, perform, distribute, and otherwise exploit its

+ such Contribution.
+
+2.3. Limitations on Grant Scope
+
+ The licenses granted in this Section 2 are the only rights granted under this
+ License. No additional rights or licenses will be implied from the distribution
+ or licensing of Covered Software under this License. Notwithstanding Section
+ 2.1(b) above, no patent license is granted by a Contributor:
+
+ a. for any code that a Contributor has removed from Covered Software; or
+
+ b. for infringements caused by: (i) Your and any other third party’s
+ modifications of Covered Software, or (ii) the combination of its
+ Contributions with other software (except as part of its Contributor
+ Version); or
+
+ c. under Patent Claims infringed by Covered Software in the absence of its
+ Contributions.
+
+ This License does not grant any rights in the trademarks, service marks, or
+ logos of any Contributor (except as may be necessary to comply with the
+ notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+ No Contributor makes additional grants as a result of Your choice to
+ distribute the Covered Software under a subsequent version of this License
+ (see Section 10.2) or under the terms of a Secondary License (if permitted
+ under the terms of Section 3.3).
+
+2.5. Representation
+
+ Each Contributor represents that the Contributor believes its Contributions
+ are its original creation(s) or it has sufficient rights to grant the
+ rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+ This License is not intended to limit any rights You have under applicable
+ copyright doctrines of fair use, fair dealing, or other equivalents.
+
+2.7. Conditions
+
+ Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+ Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+ All distribution of Covered Software in Source Code Form, including any
+ Modifications that You create or to which You contribute, must be under the
+ terms of this License. You must inform recipients that the Source Code Form
+ of the Covered Software is governed by the terms of this License, and how
+ they can obtain a copy of this License. You may not attempt to alter or
+ restrict the recipients’ rights in the Source Code Form.
+
+3.2. Distribution of Executable Form
+
+ If You distribute Covered Software in Executable Form then:
+
+ a. such Covered Software must also be made available in Source Code Form,
+ as described in Section 3.1, and You must inform recipients of the
+ Executable Form how they can obtain a copy of such Source Code Form by
+ reasonable means in a timely manner, at a charge no more than the cost
+ of distribution to the recipient; and
+
+ b. You may distribute such Executable Form under the terms of this License,
+ or sublicense it under different terms, provided that the license for
+ the Executable Form does not attempt to limit or alter the recipients’
+ rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+ You may create and distribute a Larger Work under terms of Your choice,
+ provided that You also comply with the requirements of this License for the
+ Covered Software. If the Larger Work is a combination of Covered Software
+ with a work governed by one or more Secondary Licenses, and the Covered
+ Software is not Incompatible With Secondary Licenses, this License permits
+ You to additionally distribute such Covered Software under the terms of
+ such Secondary License(s), so that the recipient of the Larger Work may, at
+ their option, further distribute the Covered Software under the terms of
+ either this License or such Secondary License(s).
+
+3.4. Notices
+
+ You may not remove or alter the substance of any license notices (including
+ copyright notices, patent notices, disclaimers of warranty, or limitations
+ of liability) contained within the Source Code Form of the Covered
+ Software, except that You may alter any license notices to the extent
+ required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+ You may choose to offer, and to charge a fee for, warranty, support,
+ indemnity or liability obligations to one or more recipients of Covered
+ Software. However, You may do so only on Your own behalf, and not on behalf
+ of any Contributor. You must make it absolutely clear that any such
+ warranty, support, indemnity, or liability obligation is offered by You
+ alone, and You hereby agree to indemnify every Contributor for any
+ liability incurred by such Contributor as a result of warranty, support,
+ indemnity or liability terms You offer. You may include additional
+ disclaimers of warranty and limitations of liability specific to any
+ jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+ If it is impossible for You to comply with any of the terms of this License
+ with respect to some or all of the Covered Software due to statute, judicial
+ order, or regulation then You must: (a) comply with the terms of this License
+ to the maximum extent possible; and (b) describe the limitations and the code
+ they affect. Such description must be placed in a text file included with all
+ distributions of the Covered Software under this License. Except to the
+ extent prohibited by statute or regulation, such description must be
+ sufficiently detailed for a recipient of ordinary skill to be able to
+ understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+ fail to comply with any of its terms. However, if You become compliant,
+ then the rights granted under this License from a particular Contributor
+ are reinstated (a) provisionally, unless and until such Contributor
+ explicitly and finally terminates Your grants, and (b) on an ongoing basis,
+ if such Contributor fails to notify You of the non-compliance by some
+ reasonable means prior to 60 days after You have come back into compliance.
+ Moreover, Your grants from a particular Contributor are reinstated on an
+ ongoing basis if such Contributor notifies You of the non-compliance by
+ some reasonable means, this is the first time You have received notice of
+ non-compliance with this License from such Contributor, and You become
+ compliant prior to 30 days after Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+ infringement claim (excluding declaratory judgment actions, counter-claims,
+ and cross-claims) alleging that a Contributor Version directly or
+ indirectly infringes any patent, then the rights granted to You by any and
+ all Contributors for the Covered Software under Section 2.1 of this License
+ shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+ license agreements (excluding distributors and resellers) which have been
+ validly granted by You or Your distributors under this License prior to
+ termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+ Covered Software is provided under this License on an “as is” basis, without
+ warranty of any kind, either expressed, implied, or statutory, including,
+ without limitation, warranties that the Covered Software is free of defects,
+ merchantable, fit for a particular purpose or non-infringing. The entire
+ risk as to the quality and performance of the Covered Software is with You.
+ Should any Covered Software prove defective in any respect, You (not any
+ Contributor) assume the cost of any necessary servicing, repair, or
+ correction. This disclaimer of warranty constitutes an essential part of this
+ License. No use of any Covered Software is authorized under this License
+ except under this disclaimer.
+
+7. Limitation of Liability
+
+ Under no circumstances and under no legal theory, whether tort (including
+ negligence), contract, or otherwise, shall any Contributor, or anyone who
+ distributes Covered Software as permitted above, be liable to You for any
+ direct, indirect, special, incidental, or consequential damages of any
+ character including, without limitation, damages for lost profits, loss of
+ goodwill, work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses, even if such party shall have been
+ informed of the possibility of such damages. This limitation of liability
+ shall not apply to liability for death or personal injury resulting from such
+ party’s negligence to the extent applicable law prohibits such limitation.
+ Some jurisdictions do not allow the exclusion or limitation of incidental or
+ consequential damages, so this exclusion and limitation may not apply to You.
+
+8. Litigation
+
+ Any litigation relating to this License may be brought only in the courts of
+ a jurisdiction where the defendant maintains its principal place of business
+ and such litigation shall be governed by laws of that jurisdiction, without
+ reference to its conflict-of-law provisions. Nothing in this Section shall
+ prevent a party’s ability to bring cross-claims or counter-claims.
+
+9. Miscellaneous
+
+ This License represents the complete agreement concerning the subject matter
+ hereof. If any provision of this License is held to be unenforceable, such
+ provision shall be reformed only to the extent necessary to make it
+ enforceable. Any law or regulation which provides that the language of a
+ contract shall be construed against the drafter shall not be used to construe
+ this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+ Mozilla Foundation is the license steward. Except as provided in Section
+ 10.3, no one other than the license steward has the right to modify or
+ publish new versions of this License. Each version will be given a
+ distinguishing version number.
+
+10.2. Effect of New Versions
+
+ You may distribute the Covered Software under the terms of the version of
+ the License under which You originally received the Covered Software, or
+ under the terms of any subsequent version published by the license
+ steward.
+
+10.3. Modified Versions
+
+ If you create software not governed by this License, and you want to
+ create a new license for such software, you may create and use a modified
+ version of this License if you rename the license and remove any
+ references to the name of the license steward (except to note that such
+ modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
+ If You choose to distribute Source Code Form that is Incompatible With
+ Secondary Licenses under the terms of this version of the License, the
+ notice described in Exhibit B of this License must be attached.

+# HCL
+
+[](https://godoc.org/github.com/hashicorp/hcl) [](https://travis-ci.org/hashicorp/hcl)
+
+HCL (HashiCorp Configuration Language) is a configuration language built
+by HashiCorp. The goal of HCL is to build a structured configuration language
+that is both human and machine friendly for use with command-line tools, but
+specifically targeted towards DevOps tools, servers, etc.
+
+HCL is also fully JSON compatible. That is, JSON can be used as completely
+valid input to a system expecting HCL. This helps makes systems
+interoperable with other systems.
+
+HCL is heavily inspired by
+[libucl](https://github.com/vstakhov/libucl),
+nginx configuration, and others similar.
+
+## Why?
+
+A common question when viewing HCL is to ask the question: why not
+JSON, YAML, etc.?
+
+Prior to HCL, the tools we built at [HashiCorp](http://www.hashicorp.com)
+used a variety of configuration languages from full programming languages
+such as Ruby to complete data structure languages such as JSON. What we
+learned is that some people wanted human-friendly configuration languages
+and some people wanted machine-friendly languages.
+
+JSON fits a nice balance in this, but is fairly verbose and most
+importantly doesn't support comments. With YAML, we found that beginners
+had a really hard time determining what the actual structure was, and
+ended up guessing more often than not whether to use a hyphen, colon, etc.
+in order to represent some configuration key.
+
+Full programming languages such as Ruby enable complex behavior
+a configuration language shouldn't usually allow, and also forces
+people to learn some set of Ruby.
+
+Because of this, we decided to create our own configuration language
+that is JSON-compatible. Our configuration language (HCL) is designed
+to be written and modified by humans. The API for HCL allows JSON
+as an input so that it is also machine-friendly (machines can generate
+JSON instead of trying to generate HCL).
+
+Our goal with HCL is not to alienate other configuration languages.
+It is instead to provide HCL as a specialized language for our tools,
+and JSON as the interoperability layer.
+
+## Syntax
+
+For a complete grammar, please see the parser itself. A high-level overview
+of the syntax and grammar is listed here.
+
+ * Single line comments start with `#` or `//`
+
+ * Multi-line comments are wrapped in `/*` and `*/`. Nested block comments
+ are not allowed. A multi-line comment (also known as a block comment)
+ terminates at the first `*/` found.
+
+ * Values are assigned with the syntax `key = value` (whitespace doesn't
+ matter). The value can be any primitive: a string, number, boolean,
+ object, or list.
+
+ * Strings are double-quoted and can contain any UTF-8 characters.
+ Example: `"Hello, World"`
+
+ * Multi-line strings start with `<<EOF` at the end of a line, and end
+ with `EOF` on its own line ([here documents](https://en.wikipedia.org/wiki/Here_document)).
+ Any text may be used in place of `EOF`. Example:
+```
+<<FOO
+hello
+world
+FOO
+```
+
+ * Numbers are assumed to be base 10. If you prefix a number with 0x,
+ it is treated as a hexadecimal. If it is prefixed with 0, it is
+ treated as an octal. Numbers can be in scientific notation: "1e10".
+
+ * Boolean values: `true`, `false`
+
+ * Arrays can be made by wrapping it in `[]`. Example:
+ `["foo", "bar", 42]`. Arrays can contain primitives,
+ other arrays, and objects. As an alternative, lists
+ of objects can be created with repeated blocks, using
+ this structure:
+
+ ```hcl
+ service {
+ key = "value"
+ }
+
+ service {
+ key = "value"
+ }
+ ```
+
+Objects and nested objects are created using the structure shown below:
+
+```
+variable "ami" {
+ description = "the AMI to use"
+}
+```
+This would be equivalent to the following json:
+``` json
+{
+ "variable": {
+ "ami": {
+ "description": "the AMI to use"
+ }
+ }
+}
+```
+
+## Thanks
+
+Thanks to:
+
+ * [@vstakhov](https://github.com/vstakhov) - The original libucl parser
+ and syntax that HCL was based off of.
+
+ * [@fatih](https://github.com/fatih) - The rewritten HCL parser
+ in pure Go (no goyacc) and support for a printer.

+go-flags: a go library for parsing command line arguments
+=========================================================
+
+[](https://godoc.org/github.com/jessevdk/go-flags) [](https://travis-ci.org/jessevdk/go-flags) [](https://coveralls.io/r/jessevdk/go-flags?branch=master)
+
+This library provides similar functionality to the builtin flag library of
+go, but provides much more functionality and nicer formatting. From the
+documentation:
+
+Package flags provides an extensive command line option parser.
+The flags package is similar in functionality to the go builtin flag package
+but provides more options and uses reflection to provide a convenient and
+succinct way of specifying command line options.
+
+Supported features:
+* Options with short names (-v)
+* Options with long names (--verbose)
+* Options with and without arguments (bool v.s. other type)
+* Options with optional arguments and default values
+* Multiple option groups each containing a set of options
+* Generate and print well-formatted help message
+* Passing remaining command line arguments after -- (optional)
+* Ignoring unknown command line options (optional)
+* Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
+* Supports multiple short options -aux
+* Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
+* Supports same option multiple times (can store in slice or last option counts)
+* Supports maps
+* Supports function callbacks
+* Supports namespaces for (nested) option groups
+
+The flags package uses structs, reflection and struct field tags
+to allow users to specify command line options. This results in very simple
+and concise specification of your application options. For example:
+
+```go
+type Options struct {
+ Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+}
+```
+
+This specifies one option with a short name -v and a long name --verbose.
+When either -v or --verbose is found on the command line, a 'true' value
+will be appended to the Verbose field. e.g. when specifying -vvv, the
+resulting value of Verbose will be {[true, true, true]}.
+
+Example:
+--------
+```go
+var opts struct {
+ // Slice of bool will append 'true' each time the option
+ // is encountered (can be set multiple times, like -vvv)
+ Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+
+ // Example of automatic marshalling to desired type (uint)
+ Offset uint `long:"offset" description:"Offset"`
+
+ // Example of a callback, called each time the option is found.
+ Call func(string) `short:"c" description:"Call phone number"`
+
+ // Example of a required flag
+ Name string `short:"n" long:"name" description:"A name" required:"true"`
+
+ // Example of a value name
+ File string `short:"f" long:"file" description:"A file" value-name:"FILE"`
+
+ // Example of a pointer
+ Ptr *int `short:"p" description:"A pointer to an integer"`
+
+ // Example of a slice of strings
+ StringSlice []string `short:"s" description:"A slice of strings"`

+

+// Note that this works just on OS X (and probably only with
+// Skype) but it shows the idea.

+Package flags provides an extensive command line option parser.
+The flags package is similar in functionality to the go built-in flag package
+but provides more options and uses reflection to provide a convenient and
+succinct way of specifying command line options.
+
+
+Supported features
+
+The following features are supported in go-flags:
+
+ Options with short names (-v)
+ Options with long names (--verbose)
+ Options with and without arguments (bool v.s. other type)
+ Options with optional arguments and default values
+ Option default values from ENVIRONMENT_VARIABLES, including slice and map values
+ Multiple option groups each containing a set of options
+ Generate and print well-formatted help message
+ Passing remaining command line arguments after -- (optional)
+ Ignoring unknown command line options (optional)
+ Supports -I/usr/include -I=/usr/include -I /usr/include option argument specification
+ Supports multiple short options -aux
+ Supports all primitive go types (string, int{8..64}, uint{8..64}, float)
+ Supports same option multiple times (can store in slice or last option counts)
+ Supports maps
+ Supports function callbacks
+ Supports namespaces for (nested) option groups
+
+Additional features specific to Windows:
+ Options with short names (/v)
+ Options with long names (/verbose)
+ Windows-style options with arguments use a colon as the delimiter
+ Modify generated help message with Windows-style / options
+ Windows style options can be disabled at build time using the "forceposix"
+ build tag
+
+
+Basic usage
+
+The flags package uses structs, reflection and struct field tags
+to allow users to specify command line options. This results in very simple
+and concise specification of your application options. For example:
+
+ type Options struct {
+ Verbose []bool `short:"v" long:"verbose" description:"Show verbose debug information"`
+ }
+
+This specifies one option with a short name -v and a long name --verbose.
+When either -v or --verbose is found on the command line, a 'true' value
+will be appended to the Verbose field. e.g. when specifying -vvv, the
+resulting value of Verbose will be {[true, true, true]}.
+
+Slice options work exactly the same as primitive type options, except that
+whenever the option is encountered, a value is appended to the slice.
+
+Map options from string to primitive type are also supported. On the command
+line, you specify the value for such an option as key:value. For example
+
+ type Options struct {
+ AuthorInfo string[string] `short:"a"`
+ }
+
+Then, the AuthorInfo map can be filled with something like
+-a name:Jesse -a "surname:van den Kieboom".
+
+Finally, for full control over the conversion between command line argument
+values and options, user defined types can choose to implement the Marshaler
+and Unmarshaler interfaces.
+
+
+Available field tags
+
+The following is a list of tags for struct fields supported by go-flags:
+
+ short: the short name of the option (single character)
+ long: the long name of the option
+ required: if non empty, makes the option required to appear on the command
+ line. If a required option is not present, the parser will
+ return ErrRequired (optional)
+ description: the description of the option (optional)
+ long-description: the long description of the option. Currently only
+ displayed in generated man pages (optional)
+ no-flag: if non-empty, this field is ignored as an option (optional)
+
+ optional: if non-empty, makes the argument of the option optional. When an
+ argument is optional it can only be specified using
+ --option=argument (optional)
+ optional-value: the value of an optional option when the option occurs
+ without an argument. This tag can be specified multiple
+ times in the case of maps or slices (optional)
+ default: the default value of an option. This tag can be specified
+ multiple times in the case of slices or maps (optional)
+ default-mask: when specified, this value will be displayed in the help
+ instead of the actual default value. This is useful
+ mostly for hiding otherwise sensitive information from
+ showing up in the help. If default-mask takes the special
+ value "-", then no default value will be shown at all
+ (optional)
+ env: the default value of the option is overridden from the
+ specified environment variable, if one has been defined.
+ (optional)
+ env-delim: the 'env' default value from environment is split into
+ multiple values with the given delimiter string, use with
+ slices and maps (optional)
+ value-name: the name of the argument value (to be shown in the help)
+ (optional)
+ choice: limits the values for an option to a set of values.
+ This tag can be specified multiple times (optional)
+ hidden: if non-empty, the option is not visible in the help or man page.
+
+ base: a base (radix) used to convert strings to integer values, the
+ default base is 10 (i.e. decimal) (optional)
+
+ ini-name: the explicit ini option name (optional)
+ no-ini: if non-empty this field is ignored as an ini option
+ (optional)
+
+ group: when specified on a struct field, makes the struct
+ field a separate group with the given name (optional)
+ namespace: when specified on a group struct field, the namespace
+ gets prepended to every option's long name and
+ subgroup's namespace of this group, separated by
+ the parser's namespace delimiter (optional)
+ command: when specified on a struct field, makes the struct
+ field a (sub)command with the given name (optional)
+ subcommands-optional: when specified on a command struct field, makes
+ any subcommands of that command optional (optional)
+ alias: when specified on a command struct field, adds the
+ specified name as an alias for the command. Can be
+ be specified multiple times to add more than one
+ alias (optional)
+ positional-args: when specified on a field with a struct type,
+ uses the fields of that struct to parse remaining
+ positional command line arguments into (in order
+ of the fields). If a field has a slice type,
+ then all remaining arguments will be added to it.
+ Positional arguments are optional by default,
+ unless the "required" tag is specified together
+ with the "positional-args" tag. The "required" tag
+ can also be set on the individual rest argument
+ fields, to require only the first N positional
+ arguments. If the "required" tag is set on the
+ rest arguments slice, then its value determines
+ the minimum amount of rest arguments that needs to
+ be provided (e.g. `required:"2"`) (optional)
+ positional-arg-name: used on a field in a positional argument struct; name
+ of the positional argument placeholder to be shown in
+ the help (optional)
+
+Either the `short:` tag or the `long:` must be specified to make the field eligible as an
+option.
+
+
+Option groups
+
+Option groups are a simple way to semantically separate your options. All
+options in a particular group are shown together in the help under the name
+of the group. Namespaces can be used to specify option long names more
+precisely and emphasize the options affiliation to their group.
+
+There are currently three ways to specify option groups.
+
+ 1. Use NewNamedParser specifying the various option groups.
+ 2. Use AddGroup to add a group to an existing parser.
+ 3. Add a struct field to the top-level options annotated with the
+ group:"group-name" tag.
+
+
+
+Commands
+
+The flags package also has basic support for commands. Commands are often
+used in monolithic applications that support various commands or actions.
+Take git for example, all of the add, commit, checkout, etc. are called
+commands. Using commands you can easily separate multiple functions of your
+application.
+
+There are currently two ways to specify a command.
+
+ 1. Use AddCommand on an existing parser.
+ 2. Add a struct field to your options struct annotated with the
+ command:"command-name" tag.
+
+The most common, idiomatic way to implement commands is to define a global
+parser instance and implement each command in a separate file. These
+command files should define a go init function which calls AddCommand on
+the global parser.
+
+When parsing ends and there is an active command and that command implements
+the Commander interface, then its Execute method will be run with the
+remaining command line arguments.
+
+Command structs can have options which become valid to parse after the
+command has been specified on the command line, in addition to the options
+of all the parent commands. I.e. considering a -v flag on the parser and an
+add command, the following are equivalent:
+
+ ./app -v add
+ ./app add -v
+
+However, if the -v flag is defined on the add command, then the first of
+the two examples above would fail since the -v flag is not defined before
+the add command.
+
+
+Completion
+
+go-flags has builtin support to provide bash completion of flags, commands
+and argument values. To use completion, the binary which uses go-flags
+can be invoked in a special environment to list completion of the current
+command line argument. It should be noted that this `executes` your application,
+and it is up to the user to make sure there are no negative side effects (for
+example from init functions).
+
+Setting the environment variable `GO_FLAGS_COMPLETION=1` enables completion
+by replacing the argument parsing routine with the completion routine which
+outputs completions for the passed arguments. The basic invocation to
+complete a set of arguments is therefore:
+
+ GO_FLAGS_COMPLETION=1 ./completion-example arg1 arg2 arg3
+
+where `completion-example` is the binary, `arg1` and `arg2` are
+the current arguments, and `arg3` (the last argument) is the argument
+to be completed. If the GO_FLAGS_COMPLETION is set to "verbose", then
+descriptions of possible completion items will also be shown, if there
+are more than 1 completion items.
+
+To use this with bash completion, a simple file can be written which
+calls the binary which supports go-flags completion:
+
+ _completion_example() {
+ # All arguments except the first one
+ args=("${COMP_WORDS[@]:1:$COMP_CWORD}")
+
+ # Only split on newlines
+ local IFS=$'\n'
+
+ # Call completion (note that the first element of COMP_WORDS is
+ # the executable itself)
+ COMPREPLY=($(GO_FLAGS_COMPLETION=1 ${COMP_WORDS[0]} "${args[@]}"))
+ return 0
+ }
+
+ complete -F _completion_example completion-example
+
+Completion requires the parser option PassDoubleDash and is therefore enforced if the environment variable GO_FLAGS_COMPLETION is set.
+
+Customized completion for argument values is supported by implementing
+the flags.Completer interface for the argument value type. An example
+of a type which does so is the flags.Filename type, an alias of string
+allowing simple filename completion. A slice or array argument value
+whose element type implements flags.Completer will also be completed.

+# Overview
+
+#### Please run `git pull --tags` to update the tags. See [below](#updated-git-tags) why.
+
+properties is a Go library for reading and writing properties files.
+
+It supports reading from multiple files or URLs and Spring style recursive
+property expansion of expressions like `${key}` to their corresponding value.
+Value expressions can refer to other keys like in `${key}` or to environment
+variables like in `${USER}`. Filenames can also contain environment variables
+like in `/home/${USER}/myapp.properties`.
+
+Properties can be decoded into structs, maps, arrays and values through
+struct tags.
+
+Comments and the order of keys are preserved. Comments can be modified
+and can be written to the output.
+
+The properties library supports both ISO-8859-1 and UTF-8 encoded data.
+
+Starting from version 1.3.0 the behavior of the MustXXX() functions is
+configurable by providing a custom `ErrorHandler` function. The default has
+changed from `panic` to `log.Fatal` but this is configurable and custom
+error handling functions can be provided. See the package documentation for
+details.
+
+Read the full documentation on [](http://godoc.org/github.com/magiconair/properties)
+
+## Getting Started
+
+```go
+import (
+ "flag"
+ "github.com/magiconair/properties"
+)
+
+func main() {
+ // init from a file
+ p := properties.MustLoadFile("${HOME}/config.properties", properties.UTF8)
+
+ // or multiple files
+ p = properties.MustLoadFiles([]string{
+ "${HOME}/config.properties",
+ "${HOME}/config-${USER}.properties",
+ }, properties.UTF8, true)
+
+ // or from a map
+ p = properties.LoadMap(map[string]string{"key": "value", "abc": "def"})
+
+ // or from a string
+ p = properties.MustLoadString("key=value\nabc=def")
+
+ // or from a URL
+ p = properties.MustLoadURL("http://host/path")
+
+ // or from multiple URLs
+ p = properties.MustLoadURL([]string{
+ "http://host/config",
+ "http://host/config-${USER}",
+ }, true)
+
+ // or from flags
+ p.MustFlag(flag.CommandLine)
+
+ // get values through getters
+ host := p.MustGetString("host")
+ port := p.GetInt("port", 8080)
+
+ // or through Decode
+ type Config struct {
+ Host string `properties:"host"`
+ Port int `properties:"port,default=9000"`
+ Accept []string `properties:"accept,default=image/png;image;gif"`
+ Timeout time.Duration `properties:"timeout,default=5s"`
+ }
+ var cfg Config
+ if err := p.Decode(&cfg); err != nil {
+ log.Fatal(err)
+ }
+}

+## ToDo
+
+* Dump contents with passwords and secrets obscured
+
+## Updated Git tags
+
+#### 13 Feb 2018
+
+I realized that all of the git tags I had pushed before v1.7.5 were lightweight tags
+and I've only recently learned that this doesn't play well with `git describe` 😞
+
+I have replaced all lightweight tags with signed tags using this script which should
+retain the commit date, name and email address. Please run `git pull --tags` to update them.
+
+Worst case you have to reclone the repo.
+
+```shell
+#!/bin/bash
+tag=$1
+echo "Updating $tag"
+date=$(git show ${tag}^0 --format=%aD | head -1)
+email=$(git show ${tag}^0 --format=%aE | head -1)
+name=$(git show ${tag}^0 --format=%aN | head -1)
+GIT_COMMITTER_DATE="$date" GIT_COMMITTER_NAME="$name" GIT_COMMITTER_EMAIL="$email" git tag -s -f ${tag} ${tag}^0 -m ${tag}
+```
+
+I apologize for the inconvenience.
+
+Frank

+# mapstructure [](https://godoc.org/github.com/mitchellh/mapstructure)
+
+mapstructure is a Go library for decoding generic map values to structures
+and vice versa, while providing helpful error handling.
+
+This library is most useful when decoding values from some data stream (JSON,
+Gob, etc.) where you don't _quite_ know the structure of the underlying data
+until you read a part of it. You can therefore read a `map[string]interface{}`
+and use this library to decode it into the proper underlying native Go
+structure.
+
+## Installation
+
+Standard `go get`:
+
+```
+$ go get github.com/mitchellh/mapstructure
+```
+
+## Usage & Example
+
+For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
+
+The `Decode` function has examples associated with it there.
+
+## But Why?!
+
+Go offers fantastic standard libraries for decoding formats such as JSON.
+The standard method is to have a struct pre-created, and populate that struct
+from the bytes of the encoded format. This is great, but the problem is if
+you have configuration or an encoding that changes slightly depending on
+specific fields. For example, consider this JSON:
+
+```json
+{
+ "type": "person",
+ "name": "Mitchell"
+}
+```
+
+Perhaps we can't populate a specific structure without first reading
+the "type" field from the JSON. We could always do two passes over the
+decoding of the JSON (reading the "type" first, and the rest later).
+However, it is much simpler to just decode this into a `map[string]interface{}`
+structure, read the "type" key, then use something like this library
+to decode it into the proper structure.

+## Contributing
+
+Thank you for your interest in go-toml! We appreciate you considering
+contributing to go-toml!
+
+The main goal is the project is to provide an easy-to-use TOML
+implementation for Go that gets the job done and gets out of your way –
+dealing with TOML is probably not the central piece of your project.
+
+As the single maintainer of go-toml, time is scarce. All help, big or
+small, is more than welcomed!
+
+### Ask questions
+
+Any question you may have, somebody else might have it too. Always feel
+free to ask them on the [issues tracker][issues-tracker]. We will try to
+answer them as clearly and quickly as possible, time permitting.
+
+Asking questions also helps us identify areas where the documentation needs
+improvement, or new features that weren't envisioned before. Sometimes, a
+seemingly innocent question leads to the fix of a bug. Don't hesitate and
+ask away!
+
+### Improve the documentation
+
+The best way to share your knowledge and experience with go-toml is to
+improve the documentation. Fix a typo, clarify an interface, add an
+example, anything goes!
+
+The documentation is present in the [README][readme] and thorough the
+source code. On release, it gets updated on [GoDoc][godoc]. To make a
+change to the documentation, create a pull request with your proposed
+changes. For simple changes like that, the easiest way to go is probably
+the "Fork this project and edit the file" button on Github, displayed at
+the top right of the file. Unless it's a trivial change (for example a
+typo), provide a little bit of context in your pull request description or
+commit message.
+
+### Report a bug
+
+Found a bug! Sorry to hear that :(. Help us and other track them down and
+fix by reporting it. [File a new bug report][bug-report] on the [issues
+tracker][issues-tracker]. The template should provide enough guidance on
+what to include. When in doubt: add more details! By reducing ambiguity and
+providing more information, it decreases back and forth and saves everyone
+time.
+
+### Code changes
+
+Want to contribute a patch? Very happy to hear that!
+
+First, some high-level rules:
+
+* A short proposal with some POC code is better than a lengthy piece of
+ text with no code. Code speaks louder than words.
+* No backward-incompatible patch will be accepted unless discussed.
+ Sometimes it's hard, and Go's lack of versioning by default does not
+ help, but we try not to break people's programs unless we absolutely have
+ to.
+* If you are writing a new feature or extending an existing one, make sure
+ to write some documentation.
+* Bug fixes need to be accompanied with regression tests.
+* New code needs to be tested.
+* Your commit messages need to explain why the change is needed, even if
+ already included in the PR description.
+
+It does sound like a lot, but those best practices are here to save time
+overall and continuously improve the quality of the project, which is
+something everyone benefits from.
+
+#### Get started
+
+The fairly standard code contribution process looks like that:
+
+1. [Fork the project][fork].
+2. Make your changes, commit on any branch you like.
+3. [Open up a pull request][pull-request]
+4. Review, potential ask for changes.
+5. Merge. You're in!
+
+Feel free to ask for help! You can create draft pull requests to gather
+some early feedback!
+
+#### Run the tests
+
+You can run tests for go-toml using Go's test tool: `go test ./...`.
+When creating a pull requests, all tests will be ran on Linux on a few Go
+versions (Travis CI), and on Windows using the latest Go version
+(AppVeyor).
+
+#### Style
+
+Try to look around and follow the same format and structure as the rest of
+the code. We enforce using `go fmt` on the whole code base.
+
+---
+
+### Maintainers-only
+
+#### Merge pull request
+
+Checklist:
+
+* Passing CI.
+* Does not introduce backward-incompatible changes (unless discussed).
+* Has relevant doc changes.
+* Has relevant unit tests.
+
+1. Merge using "squash and merge".
+2. Make sure to edit the commit message to keep all the useful information
+ nice and clean.
+3. Make sure the commit title is clear and contains the PR number (#123).
+
+#### New release
+
+1. Go to [releases][releases]. Click on "X commits to master since this
+ release".
+2. Make note of all the changes. Look for backward incompatible changes,
+ new features, and bug fixes.
+3. Pick the new version using the above and semver.
+4. Create a [new release][new-release].
+5. Follow the same format as [1.1.0][release-110].

+# go-toml
+
+Go library for the [TOML](https://github.com/mojombo/toml) format.
+
+This library supports TOML version
+[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
+
+[](http://godoc.org/github.com/pelletier/go-toml)
+[](https://github.com/pelletier/go-toml/blob/master/LICENSE)
+[](https://travis-ci.org/pelletier/go-toml)
+[](https://ci.appveyor.com/project/pelletier/go-toml/branch/master)
+[](https://codecov.io/gh/pelletier/go-toml)
+[](https://goreportcard.com/report/github.com/pelletier/go-toml)
+[](https://app.fossa.io/projects/git%2Bgithub.com%2Fpelletier%2Fgo-toml?ref=badge_shield)
+
+## Features
+
+Go-toml provides the following features for using data parsed from TOML documents:
+
+* Load TOML documents from files and string data
+* Easily navigate TOML structure using Tree
+* Mashaling and unmarshaling to and from data structures
+* Line & column position data for all parsed elements
+* [Query support similar to JSON-Path](query/)
+* Syntax errors contain line and column numbers
+
+## Import
+
+```go
+import "github.com/pelletier/go-toml"
+```
+
+## Usage example
+
+Read a TOML document:
+
+```go
+config, _ := toml.Load(`
+[postgres]
+user = "pelletier"
+password = "mypassword"`)
+// retrieve data directly
+user := config.Get("postgres.user").(string)
+
+// or using an intermediate object
+postgresConfig := config.Get("postgres").(*toml.Tree)
+password := postgresConfig.Get("password").(string)
+```
+
+Or use Unmarshal:
+
+```go
+type Postgres struct {
+ User string
+ Password string
+}
+type Config struct {
+ Postgres Postgres
+}
+
+doc := []byte(`
+[Postgres]
+User = "pelletier"
+Password = "mypassword"`)
+
+config := Config{}
+toml.Unmarshal(doc, &config)
+fmt.Println("user=", config.Postgres.User)
+```
+
+Or use a query:
+
+```go
+// use a query to gather elements without walking the tree
+q, _ := query.Compile("$..[user,password]")
+results := q.Execute(config)
+for ii, item := range results.Values() {
+ fmt.Println("Query result %d: %v", ii, item)
+}
+```
+
+## Documentation
+
+The documentation and additional examples are available at
+[godoc.org](http://godoc.org/github.com/pelletier/go-toml).
+
+## Tools
+
+Go-toml provides two handy command line tools:
+
+* `tomll`: Reads TOML files and lint them.
+
+ ```
+ go install github.com/pelletier/go-toml/cmd/tomll
+ tomll --help
+ ```
+* `tomljson`: Reads a TOML file and outputs its JSON representation.
+
+ ```
+ go install github.com/pelletier/go-toml/cmd/tomljson
+ tomljson --help
+ ```
+
+### Docker image
+
+Those tools are also availble as a Docker image from
+[dockerhub](https://hub.docker.com/r/pelletier/go-toml). For example, to
+use `tomljson`:
+
+```
+docker run -v $PWD:/workdir pelletier/go-toml tomljson /workdir/example.toml
+```
+
+Only master (`latest`) and tagged versions are published to dockerhub. You
+can build your own image as usual:
+
+```
+docker build -t go-toml .
+```
+
+## Contribute
+
+Feel free to report bugs and patches using GitHub's pull requests system on
+[pelletier/go-toml](https://github.com/pelletier/go-toml). Any feedback would be
+much appreciated!
+
+### Run tests
+
+`go test ./...`
+
+### Fuzzing
+
+The script `./fuzz.sh` is available to
+run [go-fuzz](https://github.com/dvyukov/go-fuzz) on go-toml.
+
+## Versioning
+
+Go-toml follows [Semantic Versioning](http://semver.org/). The supported version
+of [TOML](https://github.com/toml-lang/toml) is indicated at the beginning of
+this document. The last two major versions of Go are supported
+(see [Go Release Policy](https://golang.org/doc/devel/release.html#policy)).

+A FileSystem Abstraction System for Go
+
+[](https://travis-ci.org/spf13/afero) [](https://ci.appveyor.com/project/spf13/afero) [](https://godoc.org/github.com/spf13/afero) [](https://gitter.im/spf13/afero?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
+
+# Overview
+
+Afero is an filesystem framework providing a simple, uniform and universal API
+interacting with any filesystem, as an abstraction layer providing interfaces,
+types and methods. Afero has an exceptionally clean interface and simple design
+without needless constructors or initialization methods.
+
+Afero is also a library providing a base set of interoperable backend
+filesystems that make it easy to work with afero while retaining all the power
+and benefit of the os and ioutil packages.
+
+Afero provides significant improvements over using the os package alone, most
+notably the ability to create mock and testing filesystems without relying on the disk.
+
+It is suitable for use in a any situation where you would consider using the OS
+package as it provides an additional abstraction that makes it easy to use a
+memory backed file system during testing. It also adds support for the http
+filesystem for full interoperability.
+
+
+## Afero Features
+
+* A single consistent API for accessing a variety of filesystems
+* Interoperation between a variety of file system types
+* A set of interfaces to encourage and enforce interoperability between backends
+* An atomic cross platform memory backed file system
+* Support for compositional (union) file systems by combining multiple file systems acting as one
+* Specialized backends which modify existing filesystems (Read Only, Regexp filtered)
+* A set of utility functions ported from io, ioutil & hugo to be afero aware
+
+
+# Using Afero
+
+Afero is easy to use and easier to adopt.
+
+A few different ways you could use Afero:
+
+* Use the interfaces alone to define you own file system.
+* Wrap for the OS packages.
+* Define different filesystems for different parts of your application.
+* Use Afero for mock filesystems while testing
+
+## Step 1: Install Afero
+
+First use go get to install the latest version of the library.
+
+ $ go get github.com/spf13/afero
+
+Next include Afero in your application.
+```go
+import "github.com/spf13/afero"
+```
+
+## Step 2: Declare a backend
+
+First define a package variable and set it to a pointer to a filesystem.
+```go
+var AppFs = afero.NewMemMapFs()
+
+or
+
+var AppFs = afero.NewOsFs()
+```
+It is important to note that if you repeat the composite literal you
+will be using a completely new and isolated filesystem. In the case of
+OsFs it will still use the same underlying filesystem but will reduce
+the ability to drop in other filesystems as desired.
+
+## Step 3: Use it like you would the OS package
+
+Throughout your application use any function and method like you normally
+would.
+
+So if my application before had:
+```go
+os.Open('/tmp/foo')
+```
+We would replace it with:
+```go
+AppFs.Open('/tmp/foo')
+```
+
+`AppFs` being the variable we defined above.
+
+
+## List of all available functions
+
+File System Methods Available:
+```go
+Chmod(name string, mode os.FileMode) : error
+Chtimes(name string, atime time.Time, mtime time.Time) : error
+Create(name string) : File, error
+Mkdir(name string, perm os.FileMode) : error
+MkdirAll(path string, perm os.FileMode) : error
+Name() : string
+Open(name string) : File, error
+OpenFile(name string, flag int, perm os.FileMode) : File, error
+Remove(name string) : error
+RemoveAll(path string) : error
+Rename(oldname, newname string) : error
+Stat(name string) : os.FileInfo, error
+```
+File Interfaces and Methods Available:
+```go
+io.Closer
+io.Reader
+io.ReaderAt
+io.Seeker
+io.Writer
+io.WriterAt
+
+Name() : string
+Readdir(count int) : []os.FileInfo, error
+Readdirnames(n int) : []string, error
+Stat() : os.FileInfo, error
+Sync() : error
+Truncate(size int64) : error
+WriteString(s string) : ret int, err error
+```
+In some applications it may make sense to define a new package that
+simply exports the file system variable for easy access from anywhere.
+
+## Using Afero's utility functions
+
+Afero provides a set of functions to make it easier to use the underlying file systems.
+These functions have been primarily ported from io & ioutil with some developed for Hugo.
+
+The afero utilities support all afero compatible backends.
+
+The list of utilities includes:
+
+```go
+DirExists(path string) (bool, error)
+Exists(path string) (bool, error)
+FileContainsBytes(filename string, subslice []byte) (bool, error)
+GetTempDir(subPath string) string
+IsDir(path string) (bool, error)
+IsEmpty(path string) (bool, error)
+ReadDir(dirname string) ([]os.FileInfo, error)
+ReadFile(filename string) ([]byte, error)
+SafeWriteReader(path string, r io.Reader) (err error)
+TempDir(dir, prefix string) (name string, err error)
+TempFile(dir, prefix string) (f File, err error)
+Walk(root string, walkFn filepath.WalkFunc) error
+WriteFile(filename string, data []byte, perm os.FileMode) error
+WriteReader(path string, r io.Reader) (err error)
+```
+For a complete list see [Afero's GoDoc](https://godoc.org/github.com/spf13/afero)
+
+They are available under two different approaches to use. You can either call
+them directly where the first parameter of each function will be the file
+system, or you can declare a new `Afero`, a custom type used to bind these
+functions as methods to a given filesystem.
+
+### Calling utilities directly
+
+```go
+fs := new(afero.MemMapFs)
+f, err := afero.TempFile(fs,"", "ioutil-test")
+
+```
+
+### Calling via Afero
+
+```go
+fs := afero.NewMemMapFs()
+afs := &afero.Afero{Fs: fs}
+f, err := afs.TempFile("", "ioutil-test")
+```
+
+## Using Afero for Testing
+
+There is a large benefit to using a mock filesystem for testing. It has a
+completely blank state every time it is initialized and can be easily
+reproducible regardless of OS. You could create files to your heart’s content
+and the file access would be fast while also saving you from all the annoying
+issues with deleting temporary files, Windows file locking, etc. The MemMapFs
+backend is perfect for testing.
+
+* Much faster than performing I/O operations on disk
+* Avoid security issues and permissions
+* Far more control. 'rm -rf /' with confidence
+* Test setup is far more easier to do
+* No test cleanup needed
+
+One way to accomplish this is to define a variable as mentioned above.
+In your application this will be set to afero.NewOsFs() during testing you
+can set it to afero.NewMemMapFs().
+
+It wouldn't be uncommon to have each test initialize a blank slate memory
+backend. To do this I would define my `appFS = afero.NewOsFs()` somewhere
+appropriate in my application code. This approach ensures that Tests are order
+independent, with no test relying on the state left by an earlier test.
+
+Then in my tests I would initialize a new MemMapFs for each test:
+```go
+func TestExist(t *testing.T) {
+ appFS := afero.NewMemMapFs()
+ // create test files and directories
+ appFS.MkdirAll("src/a", 0755)
+ afero.WriteFile(appFS, "src/a/b", []byte("file b"), 0644)
+ afero.WriteFile(appFS, "src/c", []byte("file c"), 0644)
+ name := "src/c"
+ _, err := appFS.Stat(name)
+ if os.IsNotExist(err) {
+ t.Errorf("file \"%s\" does not exist.\n", name)
+ }
+}
+```
+
+# Available Backends
+
+## Operating System Native
+
+### OsFs
+
+The first is simply a wrapper around the native OS calls. This makes it
+very easy to use as all of the calls are the same as the existing OS
+calls. It also makes it trivial to have your code use the OS during
+operation and a mock filesystem during testing or as needed.
+
+```go
+appfs := afero.NewOsFs()
+appfs.MkdirAll("src/a", 0755))
+```
+
+## Memory Backed Storage
+
+### MemMapFs
+
+Afero also provides a fully atomic memory backed filesystem perfect for use in
+mocking and to speed up unnecessary disk io when persistence isn’t
+necessary. It is fully concurrent and will work within go routines
+safely.
+
+```go
+mm := afero.NewMemMapFs()
+mm.MkdirAll("src/a", 0755))
+```
+
+#### InMemoryFile
+
+As part of MemMapFs, Afero also provides an atomic, fully concurrent memory
+backed file implementation. This can be used in other memory backed file
+systems with ease. Plans are to add a radix tree memory stored file
+system using InMemoryFile.
+
+## Network Interfaces
+
+### SftpFs
+
+Afero has experimental support for secure file transfer protocol (sftp). Which can
+be used to perform file operations over a encrypted channel.
+
+## Filtering Backends
+
+### BasePathFs
+
+The BasePathFs restricts all operations to a given path within an Fs.
+The given file name to the operations on this Fs will be prepended with
+the base path before calling the source Fs.
+
+```go
+bp := afero.NewBasePathFs(afero.NewOsFs(), "/base/path")
+```
+
+### ReadOnlyFs
+
+A thin wrapper around the source Fs providing a read only view.
+
+```go
+fs := afero.NewReadOnlyFs(afero.NewOsFs())
+_, err := fs.Create("/file.txt")
+// err = syscall.EPERM
+```
+
+# RegexpFs
+
+A filtered view on file names, any file NOT matching
+the passed regexp will be treated as non-existing.
+Files not matching the regexp provided will not be created.
+Directories are not filtered.
+
+```go
+fs := afero.NewRegexpFs(afero.NewMemMapFs(), regexp.MustCompile(`\.txt$`))
+_, err := fs.Create("/file.html")
+// err = syscall.ENOENT
+```
+
+### HttpFs
+
+Afero provides an http compatible backend which can wrap any of the existing
+backends.
+
+The Http package requires a slightly specific version of Open which
+returns an http.File type.
+
+Afero provides an httpFs file system which satisfies this requirement.
+Any Afero FileSystem can be used as an httpFs.
+
+```go
+httpFs := afero.NewHttpFs(<ExistingFS>)
+fileserver := http.FileServer(httpFs.Dir(<PATH>)))
+http.Handle("/", fileserver)
+```
+
+## Composite Backends
+
+Afero provides the ability have two filesystems (or more) act as a single
+file system.
+
+### CacheOnReadFs
+
+The CacheOnReadFs will lazily make copies of any accessed files from the base
+layer into the overlay. Subsequent reads will be pulled from the overlay
+directly permitting the request is within the cache duration of when it was
+created in the overlay.
+
+If the base filesystem is writeable, any changes to files will be
+done first to the base, then to the overlay layer. Write calls to open file
+handles like `Write()` or `Truncate()` to the overlay first.
+
+To writing files to the overlay only, you can use the overlay Fs directly (not
+via the union Fs).
+
+Cache files in the layer for the given time.Duration, a cache duration of 0
+means "forever" meaning the file will not be re-requested from the base ever.
+
+A read-only base will make the overlay also read-only but still copy files
+from the base to the overlay when they're not present (or outdated) in the
+caching layer.
+
+```go
+base := afero.NewOsFs()
+layer := afero.NewMemMapFs()
+ufs := afero.NewCacheOnReadFs(base, layer, 100 * time.Second)
+```
+
+### CopyOnWriteFs()
+
+The CopyOnWriteFs is a read only base file system with a potentially
+writeable layer on top.
+
+Read operations will first look in the overlay and if not found there, will
+serve the file from the base.
+
+Changes to the file system will only be made in the overlay.
+
+Any attempt to modify a file found only in the base will copy the file to the
+overlay layer before modification (including opening a file with a writable
+handle).
+
+Removing and Renaming files present only in the base layer is not currently
+permitted. If a file is present in the base layer and the overlay, only the
+overlay will be removed/renamed.
+
+```go
+ base := afero.NewOsFs()
+ roBase := afero.NewReadOnlyFs(base)
+ ufs := afero.NewCopyOnWriteFs(roBase, afero.NewMemMapFs())
+
+ fh, _ = ufs.Create("/home/test/file2.txt")
+ fh.WriteString("This is a test")
+ fh.Close()
+```
+
+In this example all write operations will only occur in memory (MemMapFs)
+leaving the base filesystem (OsFs) untouched.
+
+
+## Desired/possible backends
+
+The following is a short list of possible backends we hope someone will
+implement:
+
+* SSH
+* ZIP
+* TAR
+* S3
+
+# About the project
+
+## What's in the name
+
+Afero comes from the latin roots Ad-Facere.
+
+**"Ad"** is a prefix meaning "to".
+
+**"Facere"** is a form of the root "faciō" making "make or do".
+
+The literal meaning of afero is "to make" or "to do" which seems very fitting
+for a library that allows one to make files and directories and do things with them.
+
+The English word that shares the same roots as Afero is "affair". Affair shares
+the same concept but as a noun it means "something that is made or done" or "an
+object of a particular type".
+
+It's also nice that unlike some of my other libraries (hugo, cobra, viper) it
+Googles very well.
+

+
+Easy and safe casting from one type to another in Go
+
+Don’t Panic! ... Cast
+
+## What is Cast?
+
+Cast is a library to convert between different go types in a consistent and easy way.
+
+Cast provides simple functions to easily convert a number to a string, an
+interface into a bool, etc. Cast does this intelligently when an obvious
+conversion is possible. It doesn’t make any attempts to guess what you meant,
+for example you can only convert a string to an int when it is a string
+representation of an int such as “8”. Cast was developed for use in
+[Hugo](http://hugo.spf13.com), a website engine which uses YAML, TOML or JSON
+for meta data.
+
+## Why use Cast?
+
+When working with dynamic data in Go you often need to cast or convert the data
+from one type into another. Cast goes beyond just using type assertion (though
+it uses that when possible) to provide a very straightforward and convenient
+library.
+
+If you are working with interfaces to handle things like dynamic content
+you’ll need an easy way to convert an interface into a given type. This
+is the library for you.
+
+If you are taking in data from YAML, TOML or JSON or other formats which lack
+full types, then Cast is the library for you.
+
+## Usage
+
+Cast provides a handful of To_____ methods. These methods will always return
+the desired type. **If input is provided that will not convert to that type, the
+0 or nil value for that type will be returned**.
+
+Cast also provides identical methods To_____E. These return the same result as
+the To_____ methods, plus an additional error which tells you if it successfully
+converted. Using these methods you can tell the difference between when the
+input matched the zero value or when the conversion failed and the zero value
+was returned.
+
+The following examples are merely a sample of what is available. Please review
+the code for a complete set.
+
+### Example ‘ToString’:
+
+ cast.ToString("mayonegg") // "mayonegg"
+ cast.ToString(8) // "8"
+ cast.ToString(8.31) // "8.31"
+ cast.ToString([]byte("one time")) // "one time"
+ cast.ToString(nil) // ""
+
+ var foo interface{} = "one more time"
+ cast.ToString(foo) // "one more time"
+
+
+### Example ‘ToInt’:
+
+ cast.ToInt(8) // 8
+ cast.ToInt(8.31) // 8
+ cast.ToInt("8") // 8
+ cast.ToInt(true) // 1
+ cast.ToInt(false) // 0
+
+ var eight interface{} = 8
+ cast.ToInt(eight) // 8
+ cast.ToInt(nil) // 0

+=================
+
+Seamless printing to the terminal (stdout) and logging to a io.Writer
+(file) that’s as easy to use as fmt.Println.
+
+
+Graphic by [JonnyEtc](http://jonnyetc.deviantart.com/art/And-That-s-Why-You-Always-Leave-a-Note-315311422)
+
+JWW is primarily a wrapper around the excellent standard log library. It
+provides a few advantages over using the standard log library alone.
+
+1. Ready to go out of the box.
+2. One library for both printing to the terminal and logging (to files).
+3. Really easy to log to either a temp file or a file you specify.
+
+
+I really wanted a very straightforward library that could seamlessly do
+the following things.
+
+1. Replace all the println, printf, etc statements thoughout my code with
+ something more useful
+2. Allow the user to easily control what levels are printed to stdout
+3. Allow the user to easily control what levels are logged
+4. Provide an easy mechanism (like fmt.Println) to print info to the user
+ which can be easily logged as well
+5. Due to 2 & 3 provide easy verbose mode for output and logs
+6. Not have any unnecessary initialization cruft. Just use it.
+
+# Usage
+
+## Step 1. Use it
+Put calls throughout your source based on type of feedback.
+No initialization or setup needs to happen. Just start calling things.
+
+Available Loggers are:
+
+ * TRACE
+ * DEBUG
+ * INFO
+ * WARN
+ * ERROR
+ * CRITICAL
+ * FATAL
+
+These each are loggers based on the log standard library and follow the
+standard usage. Eg.
+
+```go
+ import (
+ jww "github.com/spf13/jwalterweatherman"
+ )
+
+ ...
+
+ if err != nil {
+
+ // This is a pretty serious error and the user should know about
+ // it. It will be printed to the terminal as well as logged under the
+ // default thresholds.
+
+ jww.ERROR.Println(err)
+ }
+
+ if err2 != nil {
+ // This error isn’t going to materially change the behavior of the
+ // application, but it’s something that may not be what the user
+ // expects. Under the default thresholds, Warn will be logged, but
+ // not printed to the terminal.
+
+ jww.WARN.Println(err2)
+ }
+
+ // Information that’s relevant to what’s happening, but not very
+ // important for the user. Under the default thresholds this will be
+ // discarded.
+
+ jww.INFO.Printf("information %q", response)
+
+```
+
+NOTE: You can also use the library in a non-global setting by creating an instance of a Notebook:
+
+```go
+notepad = jww.NewNotepad(jww.LevelInfo, jww.LevelTrace, os.Stdout, ioutil.Discard, "", log.Ldate|log.Ltime)
+notepad.WARN.Println("Some warning"")
+```
+
+_Why 7 levels?_
+
+Maybe you think that 7 levels are too much for any application... and you
+are probably correct. Just because there are seven levels doesn’t mean
+that you should be using all 7 levels. Pick the right set for your needs.
+Remember they only have to mean something to your project.
+
+## Step 2. Optionally configure JWW
+
+Under the default thresholds :
+
+ * Debug, Trace & Info goto /dev/null
+ * Warn and above is logged (when a log file/io.Writer is provided)
+ * Error and above is printed to the terminal (stdout)
+
+### Changing the thresholds
+
+The threshold can be changed at any time, but will only affect calls that
+execute after the change was made.
+
+This is very useful if your application has a verbose mode. Of course you
+can decide what verbose means to you or even have multiple levels of
+verbosity.
+
+
+```go
+ import (
+ jww "github.com/spf13/jwalterweatherman"
+ )
+
+ if Verbose {
+ jww.SetLogThreshold(jww.LevelTrace)
+ jww.SetStdoutThreshold(jww.LevelInfo)
+ }
+```
+
+Note that JWW's own internal output uses log levels as well, so set the log
+level before making any other calls if you want to see what it's up to.
+
+
+### Setting a log file
+
+JWW can log to any `io.Writer`:
+
+
+```go
+
+ jww.SetLogOutput(customWriter)
+
+```
+
+
+# More information
+
+This is an early release. I’ve been using it for a while and this is the
+third interface I’ve tried. I like this one pretty well, but no guarantees
+that it won’t change a bit.
+
+I wrote this for use in [hugo](https://gohugo.io). If you are looking
+for a static website engine that’s super fast please checkout Hugo.

+
+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+ go get github.com/spf13/pflag
+
+Run tests by running:
+
+ go test github.com/spf13/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/spf13/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+ flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+There are helpers function to get values later if you have the FlagSet but
+it was difficult to keep up with all of the flag pointers in your code.
+If you have a pflag.FlagSet with a flag called 'flagname' of type int you
+can use GetInt() to get the int value. But notice that 'flagname' must exist
+and it must be an int. GetString("flagname") will fail.
+
+``` go
+i, err := flagset.GetInt("flagname")
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+ flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
+}
+flag.VarP(&flagVal, "varname", "v", "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions. The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Setting no option default values for flags
+
+After you create a flag it is possible to set the pflag.NoOptDefVal for
+the given flag. Doing this changes the meaning of the flag slightly. If
+a flag has a NoOptDefVal and the flag is set on the command line without
+an option the flag will be set to the NoOptDefVal. For example given:
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+flag.Lookup("flagname").NoOptDefVal = "4321"
+```
+
+Would result in something like
+
+| Parsed Arguments | Resulting Value |
+| ------------- | ------------- |
+| --flagname=1357 | ip=1357 |
+| --flagname | ip=4321 |
+| [nothing] | ip=1234 |
+
+## Command line flag syntax
+
+```
+--flag // boolean flags, or flags with no option default values
+--flag x // only on flags without a default value
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags
+or a flag with a default value
+
+```
+// boolean or flags where the 'no option default value' is set
+-f
+-f=true
+-abc
+but
+-b true is INVALID
+
+// non-boolean and flags without a 'no option default value'
+-n 1234
+-n=1234
+-n1234
+
+// mixed
+-abcs "hello"
+-absd="hello"
+-abcs1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## Mutating or "Normalizing" Flag names
+
+It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
+
+**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
+
+``` go
+func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+ from := []string{"-", "_"}
+ to := "."
+ for _, sep := range from {
+ name = strings.Replace(name, sep, to, -1)
+ }
+ return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
+```
+
+**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
+
+``` go
+func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+ switch name {
+ case "old-flag-name":
+ name = "new-flag-name"
+ break
+ }
+ return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
+```
+
+## Deprecating a flag or its shorthand
+It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
+
+**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
+```go
+// deprecate a flag by specifying its name and a usage message
+flags.MarkDeprecated("badflag", "please use --good-flag instead")
+```
+This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
+
+**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
+```go
+// deprecate a flag shorthand by specifying its flag name and a usage message
+flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
+```
+This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
+
+Note that usage message is essential here, and it should not be empty.
+
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
+
+## Disable sorting of flags
+`pflag` allows you to disable sorting of flags for help and usage message.
+
+**Example**:
+```go
+flags.BoolP("verbose", "v", false, "verbose output")
+flags.String("coolflag", "yeaah", "it's really cool flag")
+flags.Int("usefulflag", 777, "sometimes it's very useful")
+flags.SortFlags = false
+flags.PrintDefaults()
+```
+**Output**:
+```
+ -v, --verbose verbose output
+ --coolflag string it's really cool flag (default "yeaah")
+ --usefulflag int sometimes it's very useful (default 777)
+```
+
+
+## Supporting Go flags when using pflag
+In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
+to support flags defined by third-party dependencies (e.g. `golang/glog`).
+
+**Example**: You want to add the Go flags to the `CommandLine` flagset
+```go
+import (
+ goflag "flag"
+ flag "github.com/spf13/pflag"
+)
+
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+
+func main() {
+ flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
+ flag.Parse()
+}
+```
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
+installation.

+Package pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the GNU extensions to the POSIX recommendations
+for command-line options. See
+http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+Usage:
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+ import flag "github.com/spf13/pflag"
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+ var ip = flag.Int("flagname", 1234, "help message for flagname")
+If you like, you can bind the flag to a variable using the Var() functions.
+ var flagvar int
+ func init() {
+ flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+ }
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+ flag.Var(&flagVal, "name", "help message for flagname")
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+ flag.Parse()
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+ fmt.Println("ip has value ", *ip)
+ fmt.Println("flagvar has value ", flagvar)
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+ var ip = flag.IntP("flagname", "f", 1234, "help message")
+ var flagvar bool
+ func init() {
+ flag.BoolVarP("boolname", "b", true, "help message")
+ }
+ flag.VarP(&flagVar, "varname", "v", 1234, "help message")
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+Command line flag syntax:
+ --flag // boolean flags only
+ --flag=x
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags.
+ // boolean flags
+ -f
+ -abc
+ // non-boolean flags
+ -n 1234
+ -Ifile
+ // mixed
+ -abcs "hello"
+ -abcn1234
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+The default set of command-line flags is controlled by
+top-level functions. The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.

+[](https://travis-ci.org/spf13/viper) [](https://gitter.im/spf13/viper?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [](https://godoc.org/github.com/spf13/viper)
+
+
+## What is Viper?
+
+Viper is a complete configuration solution for Go applications including 12-Factor apps. It is designed
+to work within an application, and can handle all types of configuration needs
+and formats. It supports:
+
+* setting defaults
+* reading from JSON, TOML, YAML, HCL, and Java properties config files
+* live watching and re-reading of config files (optional)
+* reading from environment variables
+* reading from remote config systems (etcd or Consul), and watching changes
+* reading from command line flags
+* reading from buffer
+* setting explicit values
+
+Viper can be thought of as a registry for all of your applications
+configuration needs.
+
+## Why Viper?
+
+When building a modern application, you don’t want to worry about
+configuration file formats; you want to focus on building awesome software.
+Viper is here to help with that.
+
+Viper does the following for you:
+
+1. Find, load, and unmarshal a configuration file in JSON, TOML, YAML, HCL, or Java properties formats.
+2. Provide a mechanism to set default values for your different
+ configuration options.
+3. Provide a mechanism to set override values for options specified through
+ command line flags.
+4. Provide an alias system to easily rename parameters without breaking existing
+ code.
+5. Make it easy to tell the difference between when a user has provided a
+ command line or config file which is the same as the default.
+
+Viper uses the following precedence order. Each item takes precedence over the
+item below it:
+
+ * explicit call to Set
+ * flag
+ * env
+ * config
+ * key/value store
+ * default
+
+Viper configuration keys are case insensitive.
+
+## Putting Values into Viper
+
+### Establishing Defaults
+
+A good configuration system will support default values. A default value is not
+required for a key, but it’s useful in the event that a key hasn’t been set via
+config file, environment variable, remote configuration or flag.
+
+Examples:
+
+```go
+viper.SetDefault("ContentDir", "content")
+viper.SetDefault("LayoutDir", "layouts")
+viper.SetDefault("Taxonomies", map[string]string{"tag": "tags", "category": "categories"})
+```
+
+### Reading Config Files
+
+Viper requires minimal configuration so it knows where to look for config files.
+Viper supports JSON, TOML, YAML, HCL, and Java Properties files. Viper can search multiple paths, but
+currently a single Viper instance only supports a single configuration file.
+Viper does not default to any configuration search paths leaving defaults decision
+to an application.
+
+Here is an example of how to use Viper to search for and read a configuration file.
+None of the specific paths are required, but at least one path should be provided
+where a configuration file is expected.
+
+```go
+viper.SetConfigName("config") // name of config file (without extension)
+viper.AddConfigPath("/etc/appname/") // path to look for the config file in
+viper.AddConfigPath("$HOME/.appname") // call multiple times to add many search paths
+viper.AddConfigPath(".") // optionally look for config in the working directory
+err := viper.ReadInConfig() // Find and read the config file
+if err != nil { // Handle errors reading the config file
+ panic(fmt.Errorf("Fatal error config file: %s \n", err))
+}
+```
+
+### Watching and re-reading config files
+
+Viper supports the ability to have your application live read a config file while running.
+
+Gone are the days of needing to restart a server to have a config take effect,
+viper powered applications can read an update to a config file while running and
+not miss a beat.
+
+Simply tell the viper instance to watchConfig.
+Optionally you can provide a function for Viper to run each time a change occurs.
+
+**Make sure you add all of the configPaths prior to calling `WatchConfig()`**
+
+```go
+viper.WatchConfig()
+viper.OnConfigChange(func(e fsnotify.Event) {
+ fmt.Println("Config file changed:", e.Name)
+})
+```
+
+### Reading Config from io.Reader
+
+Viper predefines many configuration sources such as files, environment
+variables, flags, and remote K/V store, but you are not bound to them. You can
+also implement your own required configuration source and feed it to viper.
+
+```go
+viper.SetConfigType("yaml") // or viper.SetConfigType("YAML")
+
+// any approach to require this configuration into your program.
+var yamlExample = []byte(`
+Hacker: true
+name: steve
+hobbies:
+- skateboarding
+- snowboarding
+- go
+clothing:
+ jacket: leather
+ trousers: denim
+age: 35
+eyes : brown
+beard: true
+`)
+
+viper.ReadConfig(bytes.NewBuffer(yamlExample))
+
+viper.Get("name") // this would be "steve"
+```
+
+### Setting Overrides
+
+These could be from a command line flag, or from your own application logic.
+
+```go
+viper.Set("Verbose", true)
+viper.Set("LogFile", LogFile)
+```
+
+### Registering and Using Aliases
+
+Aliases permit a single value to be referenced by multiple keys
+
+```go
+viper.RegisterAlias("loud", "Verbose")
+
+viper.Set("verbose", true) // same result as next line
+viper.Set("loud", true) // same result as prior line
+
+viper.GetBool("loud") // true
+viper.GetBool("verbose") // true
+```
+
+### Working with Environment Variables
+
+Viper has full support for environment variables. This enables 12 factor
+applications out of the box. There are five methods that exist to aid working
+with ENV:
+
+ * `AutomaticEnv()`
+ * `BindEnv(string...) : error`
+ * `SetEnvPrefix(string)`
+ * `SetEnvKeyReplacer(string...) *strings.Replacer`
+ * `AllowEmptyEnvVar(bool)`
+
+_When working with ENV variables, it’s important to recognize that Viper
+treats ENV variables as case sensitive._
+
+Viper provides a mechanism to try to ensure that ENV variables are unique. By
+using `SetEnvPrefix`, you can tell Viper to use a prefix while reading from
+the environment variables. Both `BindEnv` and `AutomaticEnv` will use this
+prefix.
+
+`BindEnv` takes one or two parameters. The first parameter is the key name, the
+second is the name of the environment variable. The name of the environment
+variable is case sensitive. If the ENV variable name is not provided, then
+Viper will automatically assume that the key name matches the ENV variable name,
+but the ENV variable is IN ALL CAPS. When you explicitly provide the ENV
+variable name, it **does not** automatically add the prefix.
+
+One important thing to recognize when working with ENV variables is that the
+value will be read each time it is accessed. Viper does not fix the value when
+the `BindEnv` is called.
+
+`AutomaticEnv` is a powerful helper especially when combined with
+`SetEnvPrefix`. When called, Viper will check for an environment variable any
+time a `viper.Get` request is made. It will apply the following rules. It will
+check for a environment variable with a name matching the key uppercased and
+prefixed with the `EnvPrefix` if set.
+
+`SetEnvKeyReplacer` allows you to use a `strings.Replacer` object to rewrite Env
+keys to an extent. This is useful if you want to use `-` or something in your
+`Get()` calls, but want your environmental variables to use `_` delimiters. An
+example of using it can be found in `viper_test.go`.
+
+By default empty environment variables are considered unset and will fall back to
+the next configuration source. To treat empty environment variables as set, use
+the `AllowEmptyEnv` method.
+
+#### Env example
+
+```go
+SetEnvPrefix("spf") // will be uppercased automatically
+BindEnv("id")
+
+os.Setenv("SPF_ID", "13") // typically done outside of the app
+
+id := Get("id") // 13
+```
+
+### Working with Flags
+
+Viper has the ability to bind to flags. Specifically, Viper supports `Pflags`
+as used in the [Cobra](https://github.com/spf13/cobra) library.
+
+Like `BindEnv`, the value is not set when the binding method is called, but when
+it is accessed. This means you can bind as early as you want, even in an
+`init()` function.
+
+For individual flags, the `BindPFlag()` method provides this functionality.
+
+Example:
+
+```go
+serverCmd.Flags().Int("port", 1138, "Port to run Application server on")
+viper.BindPFlag("port", serverCmd.Flags().Lookup("port"))
+```
+
+You can also bind an existing set of pflags (pflag.FlagSet):
+
+Example:
+
+```go
+pflag.Int("flagname", 1234, "help message for flagname")
+
+pflag.Parse()
+viper.BindPFlags(pflag.CommandLine)
+
+i := viper.GetInt("flagname") // retrieve values from viper instead of pflag
+```
+
+The use of [pflag](https://github.com/spf13/pflag/) in Viper does not preclude
+the use of other packages that use the [flag](https://golang.org/pkg/flag/)
+package from the standard library. The pflag package can handle the flags
+defined for the flag package by importing these flags. This is accomplished
+by a calling a convenience function provided by the pflag package called
+AddGoFlagSet().
+
+Example:
+
+```go
+package main
+
+import (
+ "flag"
+ "github.com/spf13/pflag"
+)
+
+func main() {
+
+ // using standard library "flag" package
+ flag.Int("flagname", 1234, "help message for flagname")
+
+ pflag.CommandLine.AddGoFlagSet(flag.CommandLine)
+ pflag.Parse()
+ viper.BindPFlags(pflag.CommandLine)
+
+ i := viper.GetInt("flagname") // retrieve value from viper
+
+ ...
+}
+```
+
+#### Flag interfaces
+
+Viper provides two Go interfaces to bind other flag systems if you don’t use `Pflags`.
+
+`FlagValue` represents a single flag. This is a very simple example on how to implement this interface:
+
+```go
+type myFlag struct {}
+func (f myFlag) HasChanged() bool { return false }
+func (f myFlag) Name() string { return "my-flag-name" }
+func (f myFlag) ValueString() string { return "my-flag-value" }
+func (f myFlag) ValueType() string { return "string" }
+```
+
+Once your flag implements this interface, you can simply tell Viper to bind it:
+
+```go
+viper.BindFlagValue("my-flag-name", myFlag{})
+```
+
+`FlagValueSet` represents a group of flags. This is a very simple example on how to implement this interface:
+
+```go
+type myFlagSet struct {
+ flags []myFlag
+}
+
+func (f myFlagSet) VisitAll(fn func(FlagValue)) {
+ for _, flag := range flags {
+ fn(flag)
+ }
+}
+```
+
+Once your flag set implements this interface, you can simply tell Viper to bind it:
+
+```go
+fSet := myFlagSet{
+ flags: []myFlag{myFlag{}, myFlag{}},
+}
+viper.BindFlagValues("my-flags", fSet)
+```
+
+### Remote Key/Value Store Support
+
+To enable remote support in Viper, do a blank import of the `viper/remote`
+package:
+
+`import _ "github.com/spf13/viper/remote"`
+
+Viper will read a config string (as JSON, TOML, YAML or HCL) retrieved from a path
+in a Key/Value store such as etcd or Consul. These values take precedence over
+default values, but are overridden by configuration values retrieved from disk,
+flags, or environment variables.
+
+Viper uses [crypt](https://github.com/xordataexchange/crypt) to retrieve
+configuration from the K/V store, which means that you can store your
+configuration values encrypted and have them automatically decrypted if you have
+the correct gpg keyring. Encryption is optional.
+
+You can use remote configuration in conjunction with local configuration, or
+independently of it.
+
+`crypt` has a command-line helper that you can use to put configurations in your
+K/V store. `crypt` defaults to etcd on http://127.0.0.1:4001.
+
+```bash
+$ go get github.com/xordataexchange/crypt/bin/crypt
+$ crypt set -plaintext /config/hugo.json /Users/hugo/settings/config.json
+```
+
+Confirm that your value was set:
+
+```bash
+$ crypt get -plaintext /config/hugo.json
+```
+
+See the `crypt` documentation for examples of how to set encrypted values, or
+how to use Consul.
+
+### Remote Key/Value Store Example - Unencrypted
+
+#### etcd
+```go
+viper.AddRemoteProvider("etcd", "http://127.0.0.1:4001","/config/hugo.json")
+viper.SetConfigType("json") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop"
+err := viper.ReadRemoteConfig()
+```
+
+#### Consul
+You need to set a key to Consul key/value storage with JSON value containing your desired config.
+For example, create a Consul key/value store key `MY_CONSUL_KEY` with value:
+
+```json
+{
+ "port": 8080,
+ "hostname": "myhostname.com"
+}
+```
+
+```go
+viper.AddRemoteProvider("consul", "localhost:8500", "MY_CONSUL_KEY")
+viper.SetConfigType("json") // Need to explicitly set this to json
+err := viper.ReadRemoteConfig()
+
+fmt.Println(viper.Get("port")) // 8080
+fmt.Println(viper.Get("hostname")) // myhostname.com
+```
+
+### Remote Key/Value Store Example - Encrypted
+
+```go
+viper.AddSecureRemoteProvider("etcd","http://127.0.0.1:4001","/config/hugo.json","/etc/secrets/mykeyring.gpg")
+viper.SetConfigType("json") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop"
+err := viper.ReadRemoteConfig()
+```
+
+### Watching Changes in etcd - Unencrypted
+
+```go
+// alternatively, you can create a new viper instance.
+var runtime_viper = viper.New()
+
+runtime_viper.AddRemoteProvider("etcd", "http://127.0.0.1:4001", "/config/hugo.yml")
+runtime_viper.SetConfigType("yaml") // because there is no file extension in a stream of bytes, supported extensions are "json", "toml", "yaml", "yml", "properties", "props", "prop"
+
+// read from remote config the first time.
+err := runtime_viper.ReadRemoteConfig()
+
+// unmarshal config
+runtime_viper.Unmarshal(&runtime_conf)
+
+// open a goroutine to watch remote changes forever
+go func(){
+ for {
+ time.Sleep(time.Second * 5) // delay after each request
+
+ // currently, only tested with etcd support
+ err := runtime_viper.WatchRemoteConfig()
+ if err != nil {
+ log.Errorf("unable to read remote config: %v", err)
+ continue
+ }
+
+ // unmarshal new config into our runtime config struct. you can also use channel
+ // to implement a signal to notify the system of the changes
+ runtime_viper.Unmarshal(&runtime_conf)
+ }
+}()
+```
+
+## Getting Values From Viper
+
+In Viper, there are a few ways to get a value depending on the value’s type.
+The following functions and methods exist:
+
+ * `Get(key string) : interface{}`
+ * `GetBool(key string) : bool`
+ * `GetFloat64(key string) : float64`
+ * `GetInt(key string) : int`
+ * `GetString(key string) : string`
+ * `GetStringMap(key string) : map[string]interface{}`
+ * `GetStringMapString(key string) : map[string]string`
+ * `GetStringSlice(key string) : []string`
+ * `GetTime(key string) : time.Time`
+ * `GetDuration(key string) : time.Duration`
+ * `IsSet(key string) : bool`
+ * `AllSettings() : map[string]interface{}`
+
+One important thing to recognize is that each Get function will return a zero
+value if it’s not found. To check if a given key exists, the `IsSet()` method
+has been provided.
+
+Example:
+```go
+viper.GetString("logfile") // case-insensitive Setting & Getting
+if viper.GetBool("verbose") {
+ fmt.Println("verbose enabled")
+}
+```
+### Accessing nested keys
+
+The accessor methods also accept formatted paths to deeply nested keys. For
+example, if the following JSON file is loaded:
+
+```json
+{
+ "host": {
+ "address": "localhost",
+ "port": 5799
+ },
+ "datastore": {
+ "metric": {
+ "host": "127.0.0.1",
+ "port": 3099
+ },
+ "warehouse": {
+ "host": "198.0.0.1",
+ "port": 2112
+ }
+ }
+}
+
+```
+
+Viper can access a nested field by passing a `.` delimited path of keys:
+
+```go
+GetString("datastore.metric.host") // (returns "127.0.0.1")
+```
+
+This obeys the precedence rules established above; the search for the path
+will cascade through the remaining configuration registries until found.
+
+For example, given this configuration file, both `datastore.metric.host` and
+`datastore.metric.port` are already defined (and may be overridden). If in addition
+`datastore.metric.protocol` was defined in the defaults, Viper would also find it.
+
+However, if `datastore.metric` was overridden (by a flag, an environment variable,
+the `Set()` method, …) with an immediate value, then all sub-keys of
+`datastore.metric` become undefined, they are “shadowed” by the higher-priority
+configuration level.
+
+Lastly, if there exists a key that matches the delimited key path, its value
+will be returned instead. E.g.
+
+```json
+{
+ "datastore.metric.host": "0.0.0.0",
+ "host": {
+ "address": "localhost",
+ "port": 5799
+ },
+ "datastore": {
+ "metric": {
+ "host": "127.0.0.1",
+ "port": 3099
+ },
+ "warehouse": {
+ "host": "198.0.0.1",
+ "port": 2112
+ }
+ }
+}
+
+GetString("datastore.metric.host") // returns "0.0.0.0"
+```
+
+### Extract sub-tree
+
+Extract sub-tree from Viper.
+
+For example, `viper` represents:
+
+```json
+app:
+ cache1:
+ max-items: 100
+ item-size: 64
+ cache2:
+ max-items: 200
+ item-size: 80
+```
+
+After executing:
+
+```go
+subv := viper.Sub("app.cache1")
+```
+
+`subv` represents:
+
+```json
+max-items: 100
+item-size: 64
+```
+
+Suppose we have:
+
+```go
+func NewCache(cfg *Viper) *Cache {...}
+```
+
+which creates a cache based on config information formatted as `subv`.
+Now it’s easy to create these 2 caches separately as:
+
+```go
+cfg1 := viper.Sub("app.cache1")
+cache1 := NewCache(cfg1)
+
+cfg2 := viper.Sub("app.cache2")
+cache2 := NewCache(cfg2)
+```
+
+### Unmarshaling
+
+You also have the option of Unmarshaling all or a specific value to a struct, map,
+etc.
+
+There are two methods to do this:
+
+ * `Unmarshal(rawVal interface{}) : error`
+ * `UnmarshalKey(key string, rawVal interface{}) : error`
+
+Example:
+
+```go
+type config struct {
+ Port int
+ Name string
+ PathMap string `mapstructure:"path_map"`
+}
+
+var C config
+
+err := Unmarshal(&C)
+if err != nil {
+ t.Fatalf("unable to decode into struct, %v", err)
+}
+```
+
+### Marshalling to string
+
+You may need to marhsal all the settings held in viper into a string rather than write them to a file.
+You can use your favorite format's marshaller with the config returned by `AllSettings()`.
+
+```go
+import (
+ yaml "gopkg.in/yaml.v2"
+ // ...
+)
+
+func yamlStringSettings() string {
+ c := viper.AllSettings()
+ bs, err := yaml.Marshal(c)
+ if err != nil {
+ t.Fatalf("unable to marshal config to YAML: %v", err)
+ }
+ return string(bs)
+}
+```
+
+## Viper or Vipers?
+
+Viper comes ready to use out of the box. There is no configuration or
+initialization needed to begin using Viper. Since most applications will want
+to use a single central repository for their configuration, the viper package
+provides this. It is similar to a singleton.
+
+In all of the examples above, they demonstrate using viper in its singleton
+style approach.
+
+### Working with multiple vipers
+
+You can also create many different vipers for use in your application. Each will
+have its own unique set of configurations and values. Each can read from a
+different config file, key value store, etc. All of the functions that viper
+package supports are mirrored as methods on a viper.
+
+Example:
+
+```go
+x := viper.New()
+y := viper.New()
+
+x.SetDefault("ContentDir", "content")
+y.SetDefault("ContentDir", "foobar")
+
+//...
+```
+
+When working with multiple vipers, it is up to the user to keep track of the
+different vipers.
+
+## Q & A
+
+Q: Why not INI files?
+
+A: Ini files are pretty awful. There’s no standard format, and they are hard to
+validate. Viper is designed to work with JSON, TOML or YAML files. If someone
+really wants to add this feature, I’d be happy to merge it. It’s easy to specify
+which formats your application will permit.
+
+Q: Why is it called “Viper”?
+
+A: Viper is designed to be a [companion](http://en.wikipedia.org/wiki/Viper_(G.I._Joe))
+to [Cobra](https://github.com/spf13/cobra). While both can operate completely
+independently, together they make a powerful pair to handle much of your
+application foundation needs.
+
+Q: Why is it called “Cobra”?
+
+A: Is there a better name for a [commander](http://en.wikipedia.org/wiki/Cobra_Commander)?

+# webbrowser [](https://travis-ci.org/toqueteos/webbrowser) [](http://godoc.org/github.com/toqueteos/webbrowser) [](https://sourcegraph.com/github.com/toqueteos/webbrowser?badge)
+
+webbrowser provides a simple API for opening web pages on your default browser.
+
+It's inspired on [Python's webbrowser](http://docs.python.org/3/library/webbrowser.html) package but lacks some of its features (open new window).
+
+It just opens a webpage, most browsers will open it on a new tab.
+
+## Installation
+
+As simple as:
+
+```bash
+go get -u github.com/toqueteos/webbrowser
+```
+
+## Usage
+
+```go
+package main
+
+import "github.com/toqueteos/webbrowser"
+
+func main() {
+ webbrowser.Open("http://golang.org")
+}
+```
+
+That's it!
+
+## Crossplatform support
+
+The package works on:
+
+- [x] `android` (verified by 3rd party)
+- [x] `darwin`
+- [x] `freebsd` (verified by 3rd party)
+- [x] `linux`
+- [x] `netbsd` (verified by 3rd party)
+- [x] `openbsd` (verified by 3rd party)
+- [x] `windows`
+
+## License
+
+It is licensed under the MIT open source license, please see the [LICENSE.md](https://github.com/toqueteos/webbrowser/blob/master/LICENSE.md) file for more information.
+
+## Thanks...
+
+Miki Tebeka wrote a nicer version that wasn't on godoc.org when I did this, [check it out!](https://bitbucket.org/tebeka/go-wise/src/d8db9bf5c4d1/desktop.go?at=default).
+
+## Already disliking it?
+
+No problem! There's alternative libraries that may be better to your needs:
+
+- https://github.com/pkg/browser, it does what webbrowser does and more!
+- https://github.com/skratchdot/open-golang, it even provides a `xdg-open` implementation in case you don't have it!

+// Package bsoncodec provides a system for encoding values to BSON representations and decoding
+// values from BSON representations. This package considers both binary BSON and ExtendedJSON as
+// BSON representations. The types in this package enable a flexible system for handling this
+// encoding and decoding.
+//
+// The codec system is composed of two parts:
+//
+// 1) ValueEncoders and ValueDecoders that handle encoding and decoding Go values to and from BSON
+// representations.
+//
+// 2) A Registry that holds these ValueEncoders and ValueDecoders and provides methods for
+// retrieving them.
+//
+// ValueEncoders and ValueDecoders
+//
+// The ValueEncoder interface is implemented by types that can encode a provided Go type to BSON.
+// The value to encode is provided as a reflect.Value and a bsonrw.ValueWriter is used within the
+// EncodeValue method to actually create the BSON representation. For convenience, ValueEncoderFunc
+// is provided to allow use of a function with the correct signature as a ValueEncoder. An
+// EncodeContext instance is provided to allow implementations to lookup further ValueEncoders and
+// to provide configuration information.
+//
+// The ValueDecoder interface is the inverse of the ValueEncoder. Implementations should ensure that
+// the value they receive is settable. Similar to ValueEncoderFunc, ValueDecoderFunc is provided to
+// allow the use of a function with the correct signature as a ValueDecoder. A DecodeContext
+// instance is provided and serves similar functionality to the EncodeContext.
+//
+// Registry and RegistryBuilder
+//
+// A Registry is an immutable store for ValueEncoders, ValueDecoders, and a type map. For looking up
+// ValueEncoders and Decoders the Registry first attempts to find a ValueEncoder or ValueDecoder for
+// the type provided; if one cannot be found it then checks to see if a registered ValueEncoder or
+// ValueDecoder exists for an interface the type implements. Finally, the reflect.Kind of the type
+// is used to lookup a default ValueEncoder or ValueDecoder for that kind. If no ValueEncoder or
+// ValueDecoder can be found, an error is returned.
+//
+// The Registry also holds a type map. This allows users to retrieve the Go type that should be used
+// when decoding a BSON value into an empty interface. This is primarily only used for the empty
+// interface ValueDecoder.
+//
+// A RegistryBuilder is used to construct a Registry. The Register methods are used to associate
+// either a reflect.Type or a reflect.Kind with a ValueEncoder or ValueDecoder. A RegistryBuilder
+// returned from NewRegistryBuilder contains no registered ValueEncoders nor ValueDecoders and
+// contains an empty type map.
+//
+// The RegisterTypeMapEntry method handles associating a BSON type with a Go type. For example, if
+// you want to decode BSON int64 and int32 values into Go int instances, you would do the following:
+//
+// var regbuilder *RegistryBuilder = ... intType := reflect.TypeOf(int(0))
+// regbuilder.RegisterTypeMapEntry(bsontype.Int64, intType).RegisterTypeMapEntry(bsontype.Int32,
+// intType)
+//
+// DefaultValueEncoders and DefaultValueDecoders
+//
+// The DefaultValueEncoders and DefaultValueDecoders types provide a full set of ValueEncoders and
+// ValueDecoders for handling a wide range of Go types, including all of the types within the
+// primitive package. To make registering these codecs easier, a helper method on each type is
+// provided. For the DefaultValueEncoders type the method is called RegisterDefaultEncoders and for
+// the DefaultValueDecoders type the method is called RegisterDefaultDecoders, this method also
+// handles registering type map entries for each BSON type.

+// Package bson is a library for reading, writing, and manipulating BSON. The

+// The Raw family of types is used to validate and retrieve elements from a slice of bytes. This

+// type.
+//
+// Example:
+// var raw bson.Raw = ... // bytes from somewhere
+// err := raw.Validate()
+// if err != nil { return err }
+// val := raw.Lookup("foo")
+// i32, ok := val.Int32OK()

+// The D family of types is used to build concise representations of BSON using native Go types.
+// These types do not support automatic lookup.
+//
+// Example:
+// bson.D{{"foo", "bar"}, {"hello", "world"}, {"pi", 3.14159}}
+//
+//
+// Marshaling and Unmarshaling are handled with the Marshal and Unmarshal family of functions. If
+// you need to write or read BSON from a non-slice source, an Encoder or Decoder can be used with a
+// bsonrw.ValueWriter or bsonrw.ValueReader.
+//
+// Example:
+// b, err := bson.Marshal(bson.D{{"foo", "bar"}})

+// Package bsoncore contains functions that can be used to encode and decode BSON
+// elements and values to or from a slice of bytes. These functions are aimed at
+// allowing low level manipulation of BSON and can be used to build a higher
+// level BSON library.
+//
+// The Read* functions within this package return the values of the element and
+// a boolean indicating if the values are valid. A boolean was used instead of
+// an error because any error that would be returned would be the same: not
+// enough bytes. This library attempts to do no validation, it will only return
+// false if there are not enough bytes for an item to be read. For example, the
+// ReadDocument function checks the length, if that length is larger than the
+// number of bytes availble, it will return false, if there are enough bytes, it
+// will return those bytes and true. It is the consumers responsibility to
+// validate those bytes.
+//
+// The Append* functions within this package will append the type value to the
+// given dst slice. If the slice has enough capacity, it will not grow the
+// slice. The Append*Element functions within this package operate in the same
+// way, but additionally append the BSON type and the key before the value.

+// The last byte of the UTF-8-encoded rune is xor-ed with the last byte of the

+// Ａ -> A (U+FF21 -> U+0041)
+// Ｂ -> B (U+FF22 -> U+0042)
+// ...
+// By xor-ing the last byte the same entry can be shared by many mappings. This

+package cgo
+
+// This file handles cgo preprocessing of files containing `import "C"`.
+//
+// DESIGN
+//
+// The approach taken is to run the cgo processor on the package's
+// CgoFiles and parse the output, faking the filenames of the
+// resulting ASTs so that the synthetic file containing the C types is
+// called "C" (e.g. "~/go/src/net/C") and the preprocessed files
+// have their original names (e.g. "~/go/src/net/cgo_unix.go"),
+// not the names of the actual temporary files.
+//
+// The advantage of this approach is its fidelity to 'go build'. The
+// downside is that the token.Position.Offset for each AST node is
+// incorrect, being an offset within the temporary file. Line numbers
+// should still be correct because of the //line comments.
+//
+// The logic of this file is mostly plundered from the 'go build'
+// tool, which also invokes the cgo preprocessor.
+//
+//
+// REJECTED ALTERNATIVE
+//
+// An alternative approach that we explored is to extend go/types'
+// Importer mechanism to provide the identity of the importing package
+// so that each time `import "C"` appears it resolves to a different
+// synthetic package containing just the objects needed in that case.
+// The loader would invoke cgo but parse only the cgo_types.go file
+// defining the package-level objects, discarding the other files
+// resulting from preprocessing.
+//
+// The benefit of this approach would have been that source-level
+// syntax information would correspond exactly to the original cgo
+// file, with no preprocessing involved, making source tools like
+// godoc, guru, and eg happy. However, the approach was rejected
+// due to the additional complexity it would impose on go/types. (It
+// made for a beautiful demo, though.)
+//

+// CONCEPTS AND TERMINOLOGY
+//
+// The WORKSPACE is the set of packages accessible to the loader. The
+// workspace is defined by Config.Build, a *build.Context. The
+// default context treats subdirectories of $GOROOT and $GOPATH as
+// packages, but this behavior may be overridden.
+//
+// An AD HOC package is one specified as a set of source files on the
+// command line. In the simplest case, it may consist of a single file
+// such as $GOROOT/src/net/http/triv.go.
+//
+// EXTERNAL TEST packages are those comprised of a set of *_test.go
+// files all with the same 'package foo_test' declaration, all in the
+// same directory. (go/build.Package calls these files XTestFiles.)
+//
+// An IMPORTABLE package is one that can be referred to by some import
+// spec. Every importable package is uniquely identified by its
+// PACKAGE PATH or just PATH, a string such as "fmt", "encoding/json",
+// or "cmd/vendor/golang.org/x/arch/x86/x86asm". A package path
+// typically denotes a subdirectory of the workspace.
+//
+// An import declaration uses an IMPORT PATH to refer to a package.
+// Most import declarations use the package path as the import path.
+//
+// Due to VENDORING (https://golang.org/s/go15vendor), the
+// interpretation of an import path may depend on the directory in which
+// it appears. To resolve an import path to a package path, go/build
+// must search the enclosing directories for a subdirectory named
+// "vendor".
+//
+// ad hoc packages and external test packages are NON-IMPORTABLE. The
+// path of an ad hoc package is inferred from the package
+// declarations of its files and is therefore not a unique package key.
+// For example, Config.CreatePkgs may specify two initial ad hoc
+// packages, both with path "main".
+//
+// An AUGMENTED package is an importable package P plus all the
+// *_test.go files with same 'package foo' declaration as P.
+// (go/build.Package calls these files TestFiles.)
+//
+// The INITIAL packages are those specified in the configuration. A
+// DEPENDENCY is a package loaded to satisfy an import in an initial
+// package or another dependency.
+//
+package loader
+
+// IMPLEMENTATION NOTES
+//
+// 'go test', in-package test files, and import cycles
+// ---------------------------------------------------
+//
+// An external test package may depend upon members of the augmented
+// package that are not in the unaugmented package, such as functions
+// that expose internals. (See bufio/export_test.go for an example.)
+// So, the loader must ensure that for each external test package
+// it loads, it also augments the corresponding non-test package.
+//
+// The import graph over n unaugmented packages must be acyclic; the
+// import graph over n-1 unaugmented packages plus one augmented
+// package must also be acyclic. ('go test' relies on this.) But the
+// import graph over n augmented packages may contain cycles.
+//
+// First, all the (unaugmented) non-test packages and their
+// dependencies are imported in the usual way; the loader reports an
+// error if it detects an import cycle.
+//
+// Then, each package P for which testing is desired is augmented by
+// the list P' of its in-package test files, by calling
+// (*types.Checker).Files. This arrangement ensures that P' may
+// reference definitions within P, but P may not reference definitions
+// within P'. Furthermore, P' may import any other package, including
+// ones that depend upon P, without an import cycle error.
+//
+// Consider two packages A and B, both of which have lists of
+// in-package test files we'll call A' and B', and which have the
+// following import graph edges:
+// B imports A
+// B' imports A
+// A' imports B
+// This last edge would be expected to create an error were it not
+// for the special type-checking discipline above.
+// Cycles of size greater than two are possible. For example:
+// compress/bzip2/bzip2_test.go (package bzip2) imports "io/ioutil"
+// io/ioutil/tempfile_test.go (package ioutil) imports "regexp"
+// regexp/exec_test.go (package regexp) imports "compress/bzip2"
+//
+//
+// Concurrency
+// -----------
+//
+// Let us define the import dependency graph as follows. Each node is a
+// list of files passed to (Checker).Files at once. Many of these lists
+// are the production code of an importable Go package, so those nodes
+// are labelled by the package's path. The remaining nodes are
+// ad hoc packages and lists of in-package *_test.go files that augment
+// an importable package; those nodes have no label.
+//
+// The edges of the graph represent import statements appearing within a
+// file. An edge connects a node (a list of files) to the node it
+// imports, which is importable and thus always labelled.
+//
+// Loading is controlled by this dependency graph.
+//
+// To reduce I/O latency, we start loading a package's dependencies
+// asynchronously as soon as we've parsed its files and enumerated its
+// imports (scanImports). This performs a preorder traversal of the
+// import dependency graph.
+//
+// To exploit hardware parallelism, we type-check unrelated packages in
+// parallel, where "unrelated" means not ordered by the partial order of
+// the import dependency graph.
+//
+// We use a concurrency-safe non-blocking cache (importer.imported) to
+// record the results of type-checking, whether success or failure. An
+// entry is created in this cache by startLoad the first time the
+// package is imported. The first goroutine to request an entry becomes
+// responsible for completing the task and broadcasting completion to
+// subsequent requestors, which block until then.
+//
+// Type checking occurs in (parallel) postorder: we cannot type-check a
+// set of files until we have loaded and type-checked all of their
+// immediate dependencies (and thus all of their transitive
+// dependencies). If the input were guaranteed free of import cycles,
+// this would be trivial: we could simply wait for completion of the
+// dependencies and then invoke the typechecker.
+//
+// But as we saw in the 'go test' section above, some cycles in the
+// import graph over packages are actually legal, so long as the
+// cycle-forming edge originates in the in-package test files that
+// augment the package. This explains why the nodes of the import
+// dependency graph are not packages, but lists of files: the unlabelled
+// nodes avoid the cycles. Consider packages A and B where B imports A
+// and A's in-package tests AT import B. The naively constructed import
+// graph over packages would contain a cycle (A+AT) --> B --> (A+AT) but
+// the graph over lists of files is AT --> B --> A, where AT is an
+// unlabelled node.
+//
+// Awaiting completion of the dependencies in a cyclic graph would
+// deadlock, so we must materialize the import dependency graph (as
+// importer.graph) and check whether each import edge forms a cycle. If
+// x imports y, and the graph already contains a path from y to x, then
+// there is an import cycle, in which case the processing of x must not
+// wait for the completion of processing of y.
+//
+// When the type-checker makes a callback (doImport) to the loader for a
+// given import edge, there are two possible cases. In the normal case,
+// the dependency has already been completely type-checked; doImport
+// does a cache lookup and returns it. In the cyclic case, the entry in
+// the cache is still necessarily incomplete, indicating a cycle. We
+// perform the cycle check again to obtain the error message, and return
+// the error.
+//
+// The result of using concurrency is about a 2.5x speedup for stdlib_test.

+Package packages loads Go packages for inspection and analysis.
+
+The Load function takes as input a list of patterns and return a list of Package
+structs describing individual packages matched by those patterns.
+The LoadMode controls the amount of detail in the loaded packages.
+
+Load passes most patterns directly to the underlying build tool,
+but all patterns with the prefix "query=", where query is a
+non-empty string of letters from [a-z], are reserved and may be
+interpreted as query operators.
+
+Two query operators are currently supported: "file" and "pattern".
+
+The query "file=path/to/file.go" matches the package or packages enclosing
+the Go source file path/to/file.go. For example "file=~/go/src/fmt/print.go"
+might return the packages "fmt" and "fmt [fmt.test]".
+
+The query "pattern=string" causes "string" to be passed directly to
+the underlying build tool. In most cases this is unnecessary,
+but an application can use Load("pattern=" + x) as an escaping mechanism
+to ensure that x is not interpreted as a query operator if it contains '='.
+
+All other query operators are reserved for future use and currently
+cause Load to report an error.
+
+The Package struct provides basic information about the package, including
+
+ - ID, a unique identifier for the package in the returned set;
+ - GoFiles, the names of the package's Go source files;
+ - Imports, a map from source import strings to the Packages they name;
+ - Types, the type information for the package's exported symbols;
+ - Syntax, the parsed syntax trees for the package's source code; and
+ - TypeInfo, the result of a complete type-check of the package syntax trees.
+
+(See the documentation for type Package for the complete list of fields
+and more detailed descriptions.)
+
+For example,
+
+ Load(nil, "bytes", "unicode...")
+
+returns four Package structs describing the standard library packages
+bytes, unicode, unicode/utf16, and unicode/utf8. Note that one pattern
+can match multiple packages and that a package might be matched by
+multiple patterns: in general it is not possible to determine which
+packages correspond to which patterns.
+
+Note that the list returned by Load contains only the packages matched
+by the patterns. Their dependencies can be found by walking the import
+graph using the Imports fields.
+
+The Load function can be configured by passing a pointer to a Config as
+the first argument. A nil Config is equivalent to the zero Config, which
+causes Load to run in LoadFiles mode, collecting minimal information.
+See the documentation for type Config for details.
+
+As noted earlier, the Config.Mode controls the amount of detail
+reported about the loaded packages, with each mode returning all the data of the
+previous mode with some extra added. See the documentation for type LoadMode
+for details.
+
+Most tools should pass their command-line arguments (after any flags)
+uninterpreted to the loader, so that the loader can interpret them
+according to the conventions of the underlying build system.
+See the Example function for typical usage.

+package packages // import "golang.org/x/tools/go/packages"
+
+/*
+
+Motivation and design considerations
+
+The new package's design solves problems addressed by two existing
+packages: go/build, which locates and describes packages, and
+golang.org/x/tools/go/loader, which loads, parses and type-checks them.
+The go/build.Package structure encodes too much of the 'go build' way
+of organizing projects, leaving us in need of a data type that describes a
+package of Go source code independent of the underlying build system.
+We wanted something that works equally well with go build and vgo, and
+also other build systems such as Bazel and Blaze, making it possible to
+construct analysis tools that work in all these environments.
+Tools such as errcheck and staticcheck were essentially unavailable to
+the Go community at Google, and some of Google's internal tools for Go
+are unavailable externally.
+This new package provides a uniform way to obtain package metadata by
+querying each of these build systems, optionally supporting their
+preferred command-line notations for packages, so that tools integrate
+neatly with users' build environments. The Metadata query function
+executes an external query tool appropriate to the current workspace.
+
+Loading packages always returns the complete import graph "all the way down",
+even if all you want is information about a single package, because the query
+mechanisms of all the build systems we currently support ({go,vgo} list, and
+blaze/bazel aspect-based query) cannot provide detailed information
+about one package without visiting all its dependencies too, so there is
+no additional asymptotic cost to providing transitive information.
+(This property might not be true of a hypothetical 5th build system.)
+
+In calls to TypeCheck, all initial packages, and any package that
+transitively depends on one of them, must be loaded from source.
+Consider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from
+source; D may be loaded from export data, and E may not be loaded at all
+(though it's possible that D's export data mentions it, so a
+types.Package may be created for it and exposed.)
+
+The old loader had a feature to suppress type-checking of function
+bodies on a per-package basis, primarily intended to reduce the work of
+obtaining type information for imported packages. Now that imports are
+satisfied by export data, the optimization no longer seems necessary.
+
+Despite some early attempts, the old loader did not exploit export data,
+instead always using the equivalent of WholeProgram mode. This was due
+to the complexity of mixing source and export data packages (now
+resolved by the upward traversal mentioned above), and because export data
+files were nearly always missing or stale. Now that 'go build' supports
+caching, all the underlying build systems can guarantee to produce
+export data in a reasonable (amortized) time.
+
+Test "main" packages synthesized by the build system are now reported as
+first-class packages, avoiding the need for clients (such as go/ssa) to
+reinvent this generation logic.
+
+One way in which go/packages is simpler than the old loader is in its
+treatment of in-package tests. In-package tests are packages that
+consist of all the files of the library under test, plus the test files.
+The old loader constructed in-package tests by a two-phase process of
+mutation called "augmentation": first it would construct and type check
+all the ordinary library packages and type-check the packages that
+depend on them; then it would add more (test) files to the package and
+type-check again. This two-phase approach had four major problems:
+1) in processing the tests, the loader modified the library package,
+ leaving no way for a client application to see both the test
+ package and the library package; one would mutate into the other.
+2) because test files can declare additional methods on types defined in
+ the library portion of the package, the dispatch of method calls in
+ the library portion was affected by the presence of the test files.
+ This should have been a clue that the packages were logically
+ different.
+3) this model of "augmentation" assumed at most one in-package test
+ per library package, which is true of projects using 'go build',
+ but not other build systems.
+4) because of the two-phase nature of test processing, all packages that
+ import the library package had to be processed before augmentation,
+ forcing a "one-shot" API and preventing the client from calling Load
+ in several times in sequence as is now possible in WholeProgram mode.
+ (TypeCheck mode has a similar one-shot restriction for a different reason.)
+
+Early drafts of this package supported "multi-shot" operation.
+Although it allowed clients to make a sequence of calls (or concurrent
+calls) to Load, building up the graph of Packages incrementally,
+it was of marginal value: it complicated the API
+(since it allowed some options to vary across calls but not others),
+it complicated the implementation,
+it cannot be made to work in Types mode, as explained above,
+and it was less efficient than making one combined call (when this is possible).
+Among the clients we have inspected, none made multiple calls to load
+but could not be easily and satisfactorily modified to make only a single call.
+However, applications changes may be required.
+For example, the ssadump command loads the user-specified packages
+and in addition the runtime package. It is tempting to simply append
+"runtime" to the user-provided list, but that does not work if the user
+specified an ad-hoc package such as [a.go b.go].
+Instead, ssadump no longer requests the runtime package,
+but seeks it among the dependencies of the user-specified packages,
+and emits an error if it is not found.
+
+Overlays: The Overlay field in the Config allows providing alternate contents
+for Go source files, by providing a mapping from file path to contents.
+go/packages will pull in new imports added in overlay files when go/packages
+is run in LoadImports mode or greater.
+Overlay support for the go list driver isn't complete yet: if the file doesn't
+exist on disk, it will only be recognized in an overlay if it is a non-test file
+and the package would be reported even without the overlay.
+
+Questions & Tasks
+
+- Add GOARCH/GOOS?
+ They are not portable concepts, but could be made portable.
+ Our goal has been to allow users to express themselves using the conventions
+ of the underlying build system: if the build system honors GOARCH
+ during a build and during a metadata query, then so should
+ applications built atop that query mechanism.
+ Conversely, if the target architecture of the build is determined by
+ command-line flags, the application can pass the relevant
+ flags through to the build system using a command such as:
+ myapp -query_flag="--cpu=amd64" -query_flag="--os=darwin"
+ However, this approach is low-level, unwieldy, and non-portable.
+ GOOS and GOARCH seem important enough to warrant a dedicated option.
+
+- How should we handle partial failures such as a mixture of good and
+ malformed patterns, existing and non-existent packages, successful and
+ failed builds, import failures, import cycles, and so on, in a call to
+ Load?
+
+- Support bazel, blaze, and go1.10 list, not just go1.11 list.
+
+- Handle (and test) various partial success cases, e.g.
+ a mixture of good packages and:
+ invalid patterns
+ nonexistent packages
+ empty packages
+ packages with malformed package or import declarations
+ unreadable files
+ import cycles
+ other parse errors
+ type errors
+ Make sure we record errors at the correct place in the graph.
+
+- Missing packages among initial arguments are not reported.
+ Return bogus packages for them, like golist does.
+
+- "undeclared name" errors (for example) are reported out of source file
+ order. I suspect this is due to the breadth-first resolution now used
+ by go/types. Is that a bug? Discuss with gri.

+// Because we want the download cache to match the proxy protocol,
+// and because we want the proxy protocol to be possible to serve
+// from a tree of static files (which might be stored on a case-insensitive
+// file system), the proxy protocol must never require two different casings
+// of a URL path either.
+//
+// One possibility would be to make the safe encoding be the lowercase
+// hexadecimal encoding of the actual path bytes. This would avoid ever
+// needing different casings of a file path, but it would be fairly illegible
+// to most programmers when those paths appeared in the file system
+// (including in file paths in compiler errors and stack traces)
+// in web server logs, and so on. Instead, we want a safe encoding that
+// leaves most paths unaltered.
+//
+// The safe encoding is this:
+// replace every uppercase letter with an exclamation mark
+// followed by the letter's lowercase equivalent.
+//
+// For example,
+// github.com/Azure/azure-sdk-for-go -> github.com/!azure/azure-sdk-for-go.
+// github.com/GoogleCloudPlatform/cloudsql-proxy -> github.com/!google!cloud!platform/cloudsql-proxy
+// github.com/Sirupsen/logrus -> github.com/!sirupsen/logrus.
+//
+// Import paths that avoid upper-case letters are left unchanged.
+// Note that because import paths are ASCII-only and avoid various
+// problematic punctuation (like : < and >), the safe encoding is also ASCII-only
+// and avoids the same problematic punctuation.
+//
+// Import paths have never allowed exclamation marks, so there is no
+// need to define how to encode a literal !.
+//
+// Although paths are disallowed from using Unicode (see pathOK above),
+// the eventual plan is to allow Unicode letters as well, to assume that
+// file systems and URLs are Unicode-safe (storing UTF-8), and apply
+// the !-for-uppercase convention. Note however that not all runes that
+// are different but case-fold equivalent are an upper/lower pair.
+// For example, U+004B ('K'), U+006B ('k'), and U+212A ('K' for Kelvin)
+// are considered to case-fold to each other. When we do add Unicode
+// letters, we must not assume that upper/lower are the only case-equivalent pairs.
+// Perhaps the Kelvin symbol would be disallowed entirely, for example.
+// Or perhaps it would encode as "!!k", or perhaps as "(212A)".
+//
+// Also, it would be nice to allow Unicode marks as well as letters,
+// but marks include combining marks, and then we must deal not
+// only with case folding but also normalization: both U+00E9 ('é')
+// and U+0065 U+0301 ('e' followed by combining acute accent)
+// look the same on the page and are treated by some file systems
+// as the same path. If we do allow Unicode marks in paths, there
+// must be some kind of normalization to allow only one canonical
