It is based on Go's [net/html package][html] and the CSS Selector library [cascadia][]. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off. - -Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the [wiki][] for various options to do this. - -Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's `fmt` package), even though some of its methods are less than intuitive (looking at you, [index()][index]...). - -## Installation - -Please note that because of the net/html dependency, goquery requires Go1.1+. - - $ go get github.com/PuerkitoBio/goquery - -(optional) To run unit tests: - - $ cd $GOPATH/src/github.com/PuerkitoBio/goquery - $ go test - -(optional) To run benchmarks (warning: it runs for a few minutes): - - $ cd $GOPATH/src/github.com/PuerkitoBio/goquery - $ go test -bench=".*" - -## Changelog - -**Note that goquery's API is now stable, and will not break.** - -* **2016-12-29 (v1.0.2)** : Optimize allocations for `Selection.Text` (thanks to @radovskyb). -* **2016-08-28 (v1.0.1)** : Optimize performance for large documents. -* **2016-07-27 (v1.0.0)** : Tag version 1.0.0. -* **2016-06-15** : Invalid selector strings internally compile to a `Matcher` implementation that never matches any node (instead of a panic). So for example, `doc.Find("~")` returns an empty `*Selection` object. -* **2016-02-02** : Add `NodeName` utility function similar to the DOM's `nodeName` property. It returns the tag name of the first element in a selection, and other relevant values of non-element nodes (see godoc for details). Add `OuterHtml` utility function similar to the DOM's `outerHTML` property (named `OuterHtml` in small caps for consistency with the existing `Html` method on the `Selection`). -* **2015-04-20** : Add `AttrOr` helper method to return the attribute's value or a default value if absent. Thanks to [piotrkowalczuk][piotr]. -* **2015-02-04** : Add more manipulation functions - Prepend* - thanks again to [Andrew Stone][thatguystone]. -* **2014-11-28** : Add more manipulation functions - ReplaceWith*, Wrap* and Unwrap - thanks again to [Andrew Stone][thatguystone]. -* **2014-11-07** : Add manipulation functions (thanks to [Andrew Stone][thatguystone]) and `*Matcher` functions, that receive compiled cascadia selectors instead of selector strings, thus avoiding potential panics thrown by goquery via `cascadia.MustCompile` calls. This results in better performance (selectors can be compiled once and reused) and more idiomatic error handling (you can handle cascadia's compilation errors, instead of recovering from panics, which had been bugging me for a long time). Note that the actual type expected is a `Matcher` interface, that `cascadia.Selector` implements. Other matcher implementations could be used. -* **2014-11-06** : Change import paths of net/html to golang.org/x/net/html (see https://groups.google.com/forum/#!topic/golang-nuts/eD8dh3T9yyA). Make sure to update your code to use the new import path too when you call goquery with `html.Node`s. -* **v0.3.2** : Add `NewDocumentFromReader()` (thanks jweir) which allows creating a goquery document from an io.Reader. -* **v0.3.1** : Add `NewDocumentFromResponse()` (thanks assassingj) which allows creating a goquery document from an http response. -* **v0.3.0** : Add `EachWithBreak()` which allows to break out of an `Each()` loop by returning false. This function was added instead of changing the existing `Each()` to avoid breaking compatibility. -* **v0.2.1** : Make go-getable, now that [go.net/html is Go1.0-compatible][gonet] (thanks to @matrixik for pointing this out). -* **v0.2.0** : Add support for negative indices in Slice(). **BREAKING CHANGE** `Document.Root` is removed, `Document` is now a `Selection` itself (a selection of one, the root element, just like `Document.Root` was before). Add jQuery's Closest() method. -* **v0.1.1** : Add benchmarks to use as baseline for refactorings, refactor Next...() and Prev...() methods to use the new html package's linked list features (Next/PrevSibling, FirstChild). Good performance boost (40+% in some cases). -* **v0.1.0** : Initial release. - -## API - -goquery exposes two structs, `Document` and `Selection`, and the `Matcher` interface. Unlike jQuery, which is loaded as part of a DOM document, and thus acts on its containing document, goquery doesn't know which HTML document to act upon. So it needs to be told, and that's what the `Document` type is for. It holds the root document node as the initial Selection value to manipulate. - -jQuery often has many variants for the same function (no argument, a selector string argument, a jQuery object argument, a DOM element argument, ...). Instead of exposing the same features in goquery as a single method with variadic empty interface arguments, statically-typed signatures are used following this naming convention: - -* When the jQuery equivalent can be called with no argument, it has the same name as jQuery for the no argument signature (e.g.: `Prev()`), and the version with a selector string argument is called `XxxFiltered()` (e.g.: `PrevFiltered()`) -* When the jQuery equivalent **requires** one argument, the same name as jQuery is used for the selector string version (e.g.: `Is()`) -* The signatures accepting a jQuery object as argument are defined in goquery as `XxxSelection()` and take a `*Selection` object as argument (e.g.: `FilterSelection()`) -* The signatures accepting a DOM element as argument in jQuery are defined in goquery as `XxxNodes()` and take a variadic argument of type `*html.Node` (e.g.: `FilterNodes()`) -* The signatures accepting a function as argument in jQuery are defined in goquery as `XxxFunction()` and take a function as argument (e.g.: `FilterFunction()`) -* The goquery methods that can be called with a selector string have a corresponding version that take a `Matcher` interface and are defined as `XxxMatcher()` (e.g.: `IsMatcher()`) - -Utility functions that are not in jQuery but are useful in Go are implemented as functions (that take a `*Selection` as parameter), to avoid a potential naming clash on the `*Selection`'s methods (reserved for jQuery-equivalent behaviour). - -The complete [godoc reference documentation can be found here][doc]. - -Please note that Cascadia's selectors do not necessarily match all supported selectors of jQuery (Sizzle). See the [cascadia project][cascadia] for details. Invalid selector strings compile to a `Matcher` that fails to match any node. Behaviour of the various functions that take a selector string as argument follows from that fact, e.g. (where `~` is an invalid selector string): - -* `Find("~")` returns an empty selection because the selector string doesn't match anything. -* `Add("~")` returns a new selection that holds the same nodes as the original selection, because it didn't add any node (selector string didn't match anything). -* `ParentsFiltered("~")` returns an empty selection because the selector string doesn't match anything. -* `ParentsUntil("~")` returns all parents of the selection because the selector string didn't match any element to stop before the top element. - -## Examples - -See some tips and tricks in the [wiki][]. - -Adapted from example_test.go: - -```Go -package main - -import ( - "fmt" - "log" - - "github.com/PuerkitoBio/goquery" -) - -func ExampleScrape() { - doc, err := goquery.NewDocument("http://metalsucks.net") - if err != nil { - log.Fatal(err) - } - - // Find the review items - doc.Find(".sidebar-reviews article .content-block").Each(func(i int, s *goquery.Selection) { - // For each item found, get the band and title - band := s.Find("a").Text() - title := s.Find("i").Text() - fmt.Printf("Review %d: %s - %s\n", i, band, title) - }) -} - -func main() { - ExampleScrape() -} -``` - -## License - -The [BSD 3-Clause license][bsd], the same as the [Go language][golic].

You can customize it all you -want: - -```go -package main - -import ( - "os" - log "github.com/Sirupsen/logrus" -) - -func init() { - // Log as JSON instead of the default ASCII formatter. - log.SetFormatter(&log.JSONFormatter{}) - - // Output to stderr instead of stdout, could also be a file. - log.SetOutput(os.Stderr) - - // Only log the warning severity or above. - log.SetLevel(log.WarnLevel) -} - -func main() { - log.WithFields(log.Fields{ - "animal": "walrus", - "size": 10, - }).Info("A group of walrus emerges from the ocean") - - log.WithFields(log.Fields{ - "omg": true, - "number": 122, - }).Warn("The group's number increased tremendously!") - - log.WithFields(log.Fields{ - "omg": true, - "number": 100, - }).Fatal("The ice breaks!") - - // A common pattern is to re-use fields between logging statements by re-using - // the logrus.Entry returned from WithFields() - contextLogger := log.WithFields(log.Fields{ - "common": "this is a common field", - "other": "I also should be logged always", - }) - - contextLogger.Info("I'll be logged with common and other field") - contextLogger.Info("Me too") -} -``` - -For more advanced usage such as logging to multiple locations from the same -application, you can also create an instance of the `logrus` Logger: - -```go -package main - -import ( - "github.com/Sirupsen/logrus" -) - -// Create a new instance of the logger. You can have any number of instances. -var log = logrus.New() - -func main() { - // The API for setting attributes is a little different than the package level - // exported logger. See Godoc. - log.Out = os.Stderr - - log.WithFields(logrus.Fields{ - "animal": "walrus", - "size": 10, - }).Info("A group of walrus emerges from the ocean") -} -``` - -#### Fields - -Logrus encourages careful, structured logging though logging fields instead of -long, unparseable error messages. For example, instead of: `log.Fatalf("Failed -to send event %s to topic %s with key %d")`, you should log the much more -discoverable: - -```go -log.WithFields(log.Fields{ - "event": event, - "topic": topic, - "key": key, -}).Fatal("Failed to send event") -``` - -We've found this API forces you to think about logging in a way that produces -much more useful logging messages. We've been in countless situations where just -a single added field to a log statement that was already there would've saved us -hours. The `WithFields` call is optional. - -In general, with Logrus using any of the `printf`-family functions should be -seen as a hint you should add a field, however, you can still use the -`printf`-family functions with Logrus. - -#### Hooks - -You can add hooks for logging levels. For example to send errors to an exception -tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to -multiple places simultaneously, e.g. syslog. - -Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in -`init`: - -```go -import ( - log "github.com/Sirupsen/logrus" - "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "aibrake" - logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog" - "log/syslog" -) - -func init() { - - // Use the Airbrake hook to report errors that have Error severity or above to - // an exception tracker. You can create custom hooks, see the Hooks section. - log.AddHook(airbrake.NewHook(123, "xyz", "production")) - - hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "") - if err != nil { - log.Error("Unable to connect to local syslog daemon") - } else { - log.AddHook(hook) - } -} -``` -Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md). - -| Hook | Description | -| ----- | ----------- | -| [Airbrake](https://github.com/gemnasium/logrus-airbrake-hook) | Send errors to the Airbrake API V3.

Default. -log.SetLevel(log.InfoLevel) -``` - -It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose -environment if your application has that. - -#### Entries - -Besides the fields added with `WithField` or `WithFields` some fields are -automatically added to all logging events: - -1. `time`. The timestamp when the entry was created. -2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after - the `AddFields` call. E.g. `Failed to send event.` -3. `level`. The logging level. E.g. `info`. - -#### Environments - -Logrus has no notion of environment. - -If you wish for hooks and formatters to only be used in specific environments, -you should handle that yourself. For example, if your application has a global -variable `Environment`, which is a string representation of the environment you -could do: - -```go -import ( - log "github.com/Sirupsen/logrus" -) - -init() { - // do something here to set environment depending on an environment variable - // or command-line flag - if Environment == "production" { - log.SetFormatter(&log.JSONFormatter{}) - } else { - // The TextFormatter is default, you don't actually have to do this. - log.SetFormatter(&log.TextFormatter{}) - } -} -``` - -This configuration is how `logrus` was intended to be used, but JSON in -production is mostly only useful if you do log aggregation with tools like -Splunk or Logstash. - -#### Formatters - -The built-in logging formatters are: - -* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise - without colors. - * *Note:* to force colored output when there is no TTY, set the `ForceColors` - field to `true`. To force no colored output even if there is a TTY set the - `DisableColors` field to `true` -* `logrus.JSONFormatter`. Logs fields as JSON. - -Third party logging formatters: - -* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events. -* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout. -* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦. - -You can define your formatter by implementing the `Formatter` interface, -requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a -`Fields` type (`map[string]interface{}`) with all your fields as well as the -default ones (see Entries section above): - -```go -type MyJSONFormatter struct { -} - -log.SetFormatter(new(MyJSONFormatter)) - -func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) { - // Note this doesn't include Time, Level and Message which are available on - // the Entry. Consult `godoc` on information about those fields or read the - // source of the official loggers. - serialized, err := json.Marshal(entry.Data) - if err != nil { - return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err) - } - return append(serialized, '\n'), nil -} -``` - -#### Logger as an `io.Writer` - -Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it. - -```go -w := logger.Writer() -defer w.Close() - -srv := http.Server{ - // create a stdlib log.Logger that writes to - // logrus.Logger. - ErrorLog: log.New(w, "", 0), -} -``` - -Each line written to that writer will be printed the usual way, using formatters -and hooks. The level for those entries is `info`. - -#### Rotation - -Log rotation is not provided with Logrus. Log rotation should be done by an -external program (like `logrotate(8)`) that can compress and delete old log -entries. It should not be a feature of the application-level logger. - -#### Tools - -| Tool | Description | -| ---- | ----------- | -|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.| -|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper arround Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) | - -#### Testing - -Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides: - -* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook -* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any): - -```go -logger, hook := NewNullLogger() -logger.Error("Hello error") - -assert.Equal(1, len(hook.Entries)) -assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level) -assert.Equal("Hello error", hook.LastEntry().Message) - -hook.Reset() -assert.Nil(hook.LastEntry()) -``` - -#### Fatal handlers - -Logrus can register one or more functions that will be called when any `fatal` -level message is logged. The registered handlers will be executed before -logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need -to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted. - -``` -... -handler := func() { - // gracefully shutdown something... -} -logrus.RegisterExitHandler(handler) -... -``` - -#### Thread safety - -By default Logger is protected by mutex for concurrent writes, this mutex is invoked when calling hooks and writing logs. -If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking. - -Situation when locking is not needed includes: - -* You have no hooks registered, or hooks calling is already thread-safe. - -* Writing to logger.Out is already thread-safe, for example: - - 1) logger.Out is protected by locks. - - 2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing) - - (Refer to http://www.notthewizard.com/2014/06/17/are-files-appends-really-atomic/) diff --git a/vendor/github.com/Sirupsen/logrus/alt_exit.go b/vendor/github.com/Sirupsen/logrus/alt_exit.go deleted file mode 100644 index b4c9e84..0000000 --- a/vendor/github.com/Sirupsen/logrus/alt_exit.go +++ /dev/null @@ -1,64 +0,0 @@ -package logrus - -// The following code was sourced and modified from the -// https://bitbucket.org/tebeka/atexit package governed by the following license: -// -// Copyright (c) 2012 Miki Tebeka . -// -// Permission is hereby granted, free of charge, to any person obtaining a copy of -// this software and associated documentation files (the "Software"), to deal in -// the Software without restriction, including without limitation the rights to -// use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of -// the Software, and to permit persons to whom the Software is furnished to do so, -// subject to the following conditions: -// -// The above copyright notice and this permission notice shall be included in all -// copies or substantial portions of the Software. -// -// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS -// FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Things like generating help text and -parsing command flags/options should not hinder productivity when writing a -command line app. - -**This is where cli comes into play.** cli makes command line programming fun, -organized, and expressive! - -## Installation - -Make sure you have a working Go environment. Go version 1.2+ is supported. [See -the install instructions for Go](http://golang.org/doc/install.html). - -To install cli, simply run: -``` -$ go get github.com/urfave/cli -``` - -Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can -be easily used: -``` -export PATH=$PATH:$GOPATH/bin -``` - -### Supported platforms - -cli is tested against multiple versions of Go on Linux, and against the latest -released version of Go on OS X and Windows. For full details, see -[`./.travis.yml`](./.travis.yml) and [`./appveyor.yml`](./appveyor.yml). - -### Using the `v2` branch - -**Warning**: The `v2` branch is currently unreleased and considered unstable. - -There is currently a long-lived branch named `v2` that is intended to land as -the new `master` branch once development there has settled down. The current -`master` branch (mirrored as `v1`) is being manually merged into `v2` on -an irregular human-based schedule, but generally if one wants to "upgrade" to -`v2` *now* and accept the volatility (read: "awesomeness") that comes along with -that, please use whatever version pinning of your preference, such as via -`gopkg.in`: - -``` -$ go get gopkg.in/urfave/cli.v2 -``` - -``` go -... -import ( - "gopkg.in/urfave/cli.v2" // imports as package "cli" -) -... -``` - -### Pinning to the `v1` releases - -Similarly to the section above describing use of the `v2` branch, if one wants -to avoid any unexpected compatibility pains once `v2` becomes `master`, then -pinning to `v1` is an acceptable option, e.g.: - -``` -$ go get gopkg.in/urfave/cli.v1 -``` - -``` go -... -import ( - "gopkg.in/urfave/cli.v1" // imports as package "cli" -) -... -``` - -This will pull the latest tagged `v1` release (e.g. `v1.18.1` at the time of writing). - -## Getting Started - -One of the philosophies behind cli is that an API should be playful and full of -discovery. So a cli app can be as little as one line of code in `main()`. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - cli.NewApp().Run(os.Args) -} -``` - -This app will run and show help text, but is not very useful. Let's give an -action to execute and some help documentation: - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - app.Name = "boom" - app.Usage = "make an explosive entrance" - app.Action = func(c *cli.Context) error { - fmt.Println("boom! I say!") - return nil - } - - app.Run(os.Args) -} -``` - -Running this already gives you a ton of functionality, plus support for things -like subcommands and flags, which are covered below. - -## Examples - -Being a programmer can be a lonely job. Thankfully by the power of automation -that is not the case! Let's create a greeter app to fend off our demons of -loneliness! - -Start by creating a directory named `greet`, and within it, add a file, -`greet.go` with the following code in it: - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - app.Name = "greet" - app.Usage = "fight the loneliness!" - app.Action = func(c *cli.Context) error { - fmt.Println("Hello friend!") - return nil - } - - app.Run(os.Args) -} -``` - -Install our command to the `$GOPATH/bin` directory: - -``` -$ go install -``` - -Finally run our new command: - -``` -$ greet -Hello friend! -``` - -cli also generates neat help text: - -``` -$ greet help -NAME: - greet - fight the loneliness! - -USAGE: - greet [global options] command [command options] [arguments...] - -VERSION: - 0.0.0 - -COMMANDS: - help, h Shows a list of commands or help for one command - -GLOBAL OPTIONS - --version Shows version information -``` - -### Arguments - -You can lookup arguments by calling the `Args` function on `cli.Context`, e.g.: - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Action = func(c *cli.Context) error { - fmt.Printf("Hello %q", c.Args().Get(0)) - return nil - } - - app.Run(os.Args) -} -``` - -### Flags - -Setting and querying flags is simple. - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang", - Value: "english", - Usage: "language for the greeting", - }, - } - - app.Action = func(c *cli.Context) error { - name := "Nefertiti" - if c.NArg() > 0 { - name = c.Args().Get(0) - } - if c.String("lang") == "spanish" { - fmt.Println("Hola", name) - } else { - fmt.Println("Hello", name) - } - return nil - } - - app.Run(os.Args) -} -``` - -You can also set a destination variable for a flag, to which the content will be -scanned. - - -``` go -package main - -import ( - "os" - "fmt" - - "github.com/urfave/cli" -) - -func main() { - var language string - - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang", - Value: "english", - Usage: "language for the greeting", - Destination: &language, - }, - } - - app.Action = func(c *cli.Context) error { - name := "someone" - if c.NArg() > 0 { - name = c.Args()[0] - } - if language == "spanish" { - fmt.Println("Hola", name) - } else { - fmt.Println("Hello", name) - } - return nil - } - - app.Run(os.Args) -} -``` - -See full list of flags at http://godoc.org/github.com/urfave/cli - -#### Placeholder Values - -Sometimes it's useful to specify a flag's value within the usage string itself. -Such placeholders are indicated with back quotes. - -For example this: - - -```go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag{ - cli.StringFlag{ - Name: "config, c", - Usage: "Load configuration from `FILE`", - }, - } - - app.Run(os.Args) -} -``` - -Will result in help output like: - -``` ---config FILE, -c FILE Load configuration from FILE -``` - -Note that only the first placeholder is used. Subsequent back-quoted words will -be left as-is. - -#### Alternate Names - -You can set alternate (or short) names for flags by providing a comma-delimited -list for the `Name`. e.g. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - }, - } - - app.Run(os.Args) -} -``` - -That flag can then be set with `--lang spanish` or `-l spanish`. Note that -giving two different forms of the same flag in the same command invocation is an -error. - -#### Ordering - -Flags for the application and commands are shown in the order they are defined. -However, it's possible to sort them from outside this library by using `FlagsByName` -with `sort`. - -For example this: - - -``` go -package main - -import ( - "os" - "sort" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "Language for the greeting", - }, - cli.StringFlag{ - Name: "config, c", - Usage: "Load configuration from `FILE`", - }, - } - - sort.Sort(cli.FlagsByName(app.Flags)) - - app.Run(os.Args) -} -``` - -Will result in help output like: - -``` ---config FILE, -c FILE Load configuration from FILE ---lang value, -l value Language for the greeting (default: "english") -``` - -#### Values from the Environment - -You can also have the default value set from the environment via `EnvVar`. e.g. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - EnvVar: "APP_LANG", - }, - } - - app.Run(os.Args) -} -``` - -The `EnvVar` may also be given as a comma-delimited "cascade", where the first -environment variable that resolves is used as the default. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", - }, - } - - app.Run(os.Args) -} -``` - -#### Values from alternate input sources (YAML, TOML, and others) - -There is a separate package altsrc that adds support for getting flag values -from other file input sources. - -Currently supported input source formats: -* YAML -* TOML - -In order to get values for a flag from an alternate input source the following -code would be added to wrap an existing cli.Flag like below: - -``` go - altsrc.NewIntFlag(cli.IntFlag{Name: "test"}) -``` - -Initialization must also occur for these flags. Below is an example initializing -getting data from a yaml file below. - -``` go - command.Before = altsrc.InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load")) -``` - -The code above will use the "load" string as a flag name to get the file name of -a yaml file from the cli.Context. It will then use that file name to initialize -the yaml input source for any flags that are defined on that command. As a note -the "load" flag used would also have to be defined on the command flags in order -for this code snipped to work. - -Currently only the aboved specified formats are supported but developers can -add support for other input sources by implementing the -altsrc.InputSourceContext for their given sources. - -Here is a more complete sample of a command using YAML support: - - -``` go -package notmain - -import ( - "fmt" - "os" - - "github.com/urfave/cli" - "github.com/urfave/cli/altsrc" -) - -func main() { - app := cli.NewApp() - - flags := []cli.Flag{ - altsrc.NewIntFlag(cli.IntFlag{Name: "test"}), - cli.StringFlag{Name: "load"}, - } - - app.Action = func(c *cli.Context) error { - fmt.Println("yaml ist rad") - return nil - } - - app.Before = altsrc.InitInputSourceWithContext(flags, altsrc.NewYamlSourceFromFlagFunc("load")) - app.Flags = flags - - app.Run(os.Args) -} -``` - -### Subcommands - -Subcommands can be defined for a more git-like command line app. - - -```go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Commands = []cli.Command{ - { - Name: "add", - Aliases: []string{"a"}, - Usage: "add a task to the list", - Action: func(c *cli.Context) error { - fmt.Println("added task: ", c.Args().First()) - return nil - }, - }, - { - Name: "complete", - Aliases: []string{"c"}, - Usage: "complete a task on the list", - Action: func(c *cli.Context) error { - fmt.Println("completed task: ", c.Args().First()) - return nil - }, - }, - { - Name: "template", - Aliases: []string{"t"}, - Usage: "options for task templates", - Subcommands: []cli.Command{ - { - Name: "add", - Usage: "add a new template", - Action: func(c *cli.Context) error { - fmt.Println("new task template: ", c.Args().First()) - return nil - }, - }, - { - Name: "remove", - Usage: "remove an existing template", - Action: func(c *cli.Context) error { - fmt.Println("removed task template: ", c.Args().First()) - return nil - }, - }, - }, - }, - } - - app.Run(os.Args) -} -``` - -### Subcommands categories - -For additional organization in apps that have many subcommands, you can -associate a category for each command to group them together in the help -output. - -E.g. - -```go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Commands = []cli.Command{ - { - Name: "noop", - }, - { - Name: "add", - Category: "template", - }, - { - Name: "remove", - Category: "template", - }, - } - - app.Run(os.Args) -} -``` - -Will include: - -``` -COMMANDS: - noop - - Template actions: - add - remove -``` - -### Exit code - -Calling `App.Run` will not automatically call `os.Exit`, which means that by -default the exit code will "fall through" to being `0`. An explicit exit code -may be set by returning a non-nil error that fulfills `cli.ExitCoder`, *or* a -`cli.MultiError` that includes an error that fulfills `cli.ExitCoder`, e.g.: - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - app.Flags = []cli.Flag{ - cli.BoolTFlag{ - Name: "ginger-crouton", - Usage: "is it in the soup?", - }, - } - app.Action = func(ctx *cli.Context) error { - if !ctx.Bool("ginger-crouton") { - return cli.NewExitError("it is not in the soup", 86) - } - return nil - } - - app.Run(os.Args) -} -``` - -### Bash Completion - -You can enable completion commands by setting the `EnableBashCompletion` -flag on the `App` object. By default, this setting will only auto-complete to -show an app's subcommands, but you can write your own completion methods for -the App or its subcommands. - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - tasks := []string{"cook", "clean", "laundry", "eat", "sleep", "code"} - - app := cli.NewApp() - app.EnableBashCompletion = true - app.Commands = []cli.Command{ - { - Name: "complete", - Aliases: []string{"c"}, - Usage: "complete a task on the list", - Action: func(c *cli.Context) error { - fmt.Println("completed task: ", c.Args().First()) - return nil - }, - BashComplete: func(c *cli.Context) { - // This will complete if no args are passed - if c.NArg() > 0 { - return - } - for _, t := range tasks { - fmt.Println(t) - } - }, - }, - } - - app.Run(os.Args) -} -``` - -#### Enabling - -Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while -setting the `PROG` variable to the name of your program: - -`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete` - -#### Distribution - -Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename -it to the name of the program you wish to add autocomplete support for (or -automatically install it there if you are distributing a package). Don't forget -to source the file to make it active in the current shell. - -``` -sudo cp src/bash_autocomplete /etc/bash_completion.d/ -source /etc/bash_completion.d/ -``` - -Alternatively, you can just document that users should source the generic -`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set -to the name of their program (as above). - -#### Customization - -The default bash completion flag (`--generate-bash-completion`) is defined as -`cli.BashCompletionFlag`, and may be redefined if desired, e.g.: - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - cli.BashCompletionFlag = cli.BoolFlag{ - Name: "compgen", - Hidden: true, - } - - app := cli.NewApp() - app.EnableBashCompletion = true - app.Commands = []cli.Command{ - { - Name: "wat", - }, - } - app.Run(os.Args) -} -``` - -### Generated Help Text - -The default help flag (`-h/--help`) is defined as `cli.HelpFlag` and is checked -by the cli internals in order to print generated help text for the app, command, -or subcommand, and break execution. - -#### Customization - -All of the help text generation may be customized, and at multiple levels. The -templates are exposed as variables `AppHelpTemplate`, `CommandHelpTemplate`, and -`SubcommandHelpTemplate` which may be reassigned or augmented, and full override -is possible by assigning a compatible func to the `cli.HelpPrinter` variable, -e.g.: - - -``` go -package main - -import ( - "fmt" - "io" - "os" - - "github.com/urfave/cli" -) - -func main() { - // EXAMPLE: Append to an existing template - cli.AppHelpTemplate = fmt.Sprintf(`%s - -WEBSITE: http://awesometown.example.com - -SUPPORT: support@awesometown.example.com - -`, cli.AppHelpTemplate) - - // EXAMPLE: Override a template - cli.AppHelpTemplate = `NAME: - {{.Name}} - {{.Usage}} -USAGE: - {{.HelpName}} {{if .VisibleFlags}}[global options]{{end}}{{if .Commands}} command -[command options]{{end}} {{if -.ArgsUsage}}{{.ArgsUsage}}{{else}}[arguments...]{{end}} - {{if len .Authors}} -AUTHOR(S): - {{range .Authors}}{{ . }}{{end}} - {{end}}{{if .Commands}} -COMMANDS: -{{range .Commands}}{{if not .HideHelp}} {{join .Names ", "}}{{ "\t" -}}{{.Usage}}{{ "\n" }}{{end}}{{end}}{{end}}{{if .VisibleFlags}} -GLOBAL OPTIONS: - {{range .VisibleFlags}}{{.}} - {{end}}{{end}}{{if .Copyright }} -COPYRIGHT: - {{.Copyright}} - {{end}}{{if .Version}} -VERSION: - {{.Version}} - {{end}} -` - - // EXAMPLE: Replace the `HelpPrinter` func - cli.HelpPrinter = func(w io.Writer, templ string, data interface{}) { - fmt.Println("Ha HA.
