Flags can be placed before or after the command (as long as a +confusing space isn’t provided). Both short and long flags can be used. A +command need not even be fully typed. Help is automatically generated and +available for the application or for a specific command using either the help +command or the `--help` flag. + +# Concepts + +Cobra is built on a structure of commands, arguments & flags. + +**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions. + +The best applications will read like sentences when used. Users will know how +to use the application because they will natively understand how to use it. + +The pattern to follow is +`APPNAME VERB NOUN --ADJECTIVE.` + or +`APPNAME COMMAND ARG --FLAG` + +A few good real world examples may better illustrate this point. + +In the following example, 'server' is a command, and 'port' is a flag: + + > hugo server --port=1313 + +In this command we are telling Git to clone the url bare. + + > git clone URL --bare + +## Commands + +Command is the central point of the application. Each interaction that +the application supports will be contained in a Command. A command can +have children commands and optionally run an action. + +In the example above, 'server' is the command. + +A Command has the following structure: + +```go +type Command struct { + Use string // The one-line usage message. + Short string // The short description shown in the 'help' output. + Long string // The long message shown in the 'help ' output. + Run func(cmd *Command, args []string) // Run runs the command. +} +``` + +## Flags + +A Flag is a way to modify the behavior of a command. Cobra supports +fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/). +A Cobra command can define flags that persist through to children commands +and flags that are only available to that command. + +In the example above, 'port' is the flag. + +Flag functionality is provided by the [pflag +library](https://github.com/ogier/pflag), a fork of the flag standard library +which maintains the same interface while adding POSIX compliance. + +## Usage + +Cobra works by creating a set of commands and then organizing them into a tree. +The tree defines the structure of the application. + +Once each command is defined with its corresponding flags, then the +tree is assigned to the commander which is finally executed. + +# Installing +Using Cobra is easy. First, use `go get` to install the latest version +of the library. This command will install the `cobra` generator executible +along with the library: + + > go get -v github.com/spf13/cobra/cobra + +Next, include Cobra in your application: + +```go +import "github.com/spf13/cobra" +``` + +# Getting Started + +While you are welcome to provide your own organization, typically a Cobra based +application will follow the following organizational structure. + +``` + ▾ appName/ + ▾ cmd/ + add.go + your.go + commands.go + here.go + main.go +``` + +In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra. + +```go +package main + +import "{pathToYourApp}/cmd" + +func main() { + if err := cmd.RootCmd.Execute(); err != nil { + fmt.Println(err) + os.Exit(-1) + } +} +``` + +## Using the Cobra Generator + +Cobra provides its own program that will create your application and add any +commands you want. It's the easiest way to incorporate Cobra into your application. + +In order to use the cobra command, compile it using the following command: + + > go install github.com/spf13/cobra/cobra + +This will create the cobra executable under your go path bin directory! + +### cobra init + +The `cobra init [yourApp]` command will create your initial application code +for you. It is a very powerful application that will populate your program with +the right structure so you can immediately enjoy all the benefits of Cobra. It +will also automatically apply the license you specify to your application. + +Cobra init is pretty smart. You can provide it a full path, or simply a path +similar to what is expected in the import. + +``` +cobra init github.com/spf13/newAppName +``` + +### cobra add + +Once an application is initialized Cobra can create additional commands for you. +Let's say you created an app and you wanted the following commands for it: + +* app serve +* app config +* app config create + +In your project directory (where your main.go file is) you would run the following: + +``` +cobra add serve +cobra add config +cobra add create -p 'configCmd' +``` + +Once you have run these three commands you would have an app structure that would look like: + +``` + ▾ app/ + ▾ cmd/ + serve.go + config.go + create.go + main.go +``` + +at this point you can run `go run main.go` and it would run your app. `go run +main.go serve`, `go run main.go config`, `go run main.go config create` along +with `go run main.go help serve`, etc would all work. + +Obviously you haven't added your own code to these yet, the commands are ready +for you to give them their tasks. Have fun. + +### Configuring the cobra generator + +The cobra generator will be easier to use if you provide a simple configuration +file which will help you eliminate providing a bunch of repeated information in +flags over and over. + +An example ~/.cobra.yaml file: + +```yaml +author: Steve Francia +license: MIT +``` + +You can specify no license by setting `license` to `none` or you can specify +a custom license: + +```yaml +license: + header: This file is part of {{ .appName }}. + text: | + {{ .copyright }} + + This is my license. There are many like it, but this one is mine. + My license is my best friend. It is my life. I must master it as I must + master my life. +``` + +## Manually implementing Cobra + +To manually implement cobra you need to create a bare main.go file and a RootCmd file. +You will optionally provide additional commands as you see fit. + +### Create the root command + +The root command represents your binary itself. + + +#### Manually create rootCmd + +Cobra doesn't require any special constructors. Simply create your commands. + +Ideally you place this in app/cmd/root.go: + +```go +var RootCmd = &cobra.Command{ + Use: "hugo", + Short: "Hugo is a very fast static site generator", + Long: `A Fast and Flexible Static Site Generator built with + love by spf13 and friends in Go. + Complete documentation is available at http://hugo.spf13.com`, + Run: func(cmd *cobra.Command, args []string) { + // Do Stuff Here + }, +} +``` + +You will additionally define flags and handle configuration in your init() function. + +for example cmd/root.go: + +```go +func init() { + cobra.OnInitialize(initConfig) + RootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)") + RootCmd.PersistentFlags().StringVarP(&projectBase, "projectbase", "b", "", "base project directory eg. github.com/spf13/") + RootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "Author name for copyright attribution") + RootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "Name of license for the project (can provide `licensetext` in config)") + RootCmd.PersistentFlags().Bool("viper", true, "Use Viper for configuration") + viper.BindPFlag("author", RootCmd.PersistentFlags().Lookup("author")) + viper.BindPFlag("projectbase", RootCmd.PersistentFlags().Lookup("projectbase")) + viper.BindPFlag("useViper", RootCmd.PersistentFlags().Lookup("viper")) + viper.SetDefault("author", "NAME HERE ") + viper.SetDefault("license", "apache") +} +``` + +### Create your main.go + +With the root command you need to have your main function execute it. +Execute should be run on the root for clarity, though it can be called on any command. + +In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra. + +```go +package main + +import "{pathToYourApp}/cmd" + +func main() { + if err := cmd.RootCmd.Execute(); err != nil { + fmt.Println(err) + os.Exit(-1) + } +} +``` + + +### Create additional commands + +Additional commands can be defined and typically are each given their own file +inside of the cmd/ directory. + +If you wanted to create a version command you would create cmd/version.go and +populate it with the following: + +```go +package cmd + +import ( + "github.com/spf13/cobra" +) + +func init() { + RootCmd.AddCommand(versionCmd) +} + +var versionCmd = &cobra.Command{ + Use: "version", + Short: "Print the version number of Hugo", + Long: `All software has versions. This is Hugo's`, + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Hugo Static Site Generator v0.9 -- HEAD") + }, +} +``` + +### Attach command to its parent + + +If you notice in the above example we attach the command to its parent. In +this case the parent is the rootCmd. In this example we are attaching it to the +root, but commands can be attached at any level. + +```go +RootCmd.AddCommand(versionCmd) +``` + +### Remove a command from its parent + +Removing a command is not a common action in simple programs, but it allows 3rd +parties to customize an existing command tree. + +In this example, we remove the existing `VersionCmd` command of an existing +root command, and we replace it with our own version: + +```go +mainlib.RootCmd.RemoveCommand(mainlib.VersionCmd) +mainlib.RootCmd.AddCommand(versionCmd) +``` + +## Working with Flags + +Flags provide modifiers to control how the action command operates. + +### Assign flags to a command + +Since the flags are defined and used in different locations, we need to +define a variable outside with the correct scope to assign the flag to +work with. + +```go +var Verbose bool +var Source string +``` + +There are two different approaches to assign a flag. + +### Persistent Flags + +A flag can be 'persistent' meaning that this flag will be available to the +command it's assigned to as well as every command under that command. For +global flags, assign a flag as a persistent flag on the root. + +```go +RootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output") +``` + +### Local Flags + +A flag can also be assigned locally which will only apply to that specific command. + +```go +RootCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from") +``` + + +## Example + +In the example below, we have defined three commands. Two are at the top level +and one (cmdTimes) is a child of one of the top commands. In this case the root +is not executable meaning that a subcommand is required. This is accomplished +by not providing a 'Run' for the 'rootCmd'. + +We have only defined one flag for a single command. + +More documentation about flags is available at https://github.com/spf13/pflag + +```go +package main + +import ( + "fmt" + "strings" + + "github.com/spf13/cobra" +) + +func main() { + + var echoTimes int + + var cmdPrint = &cobra.Command{ + Use: "print [string to print]", + Short: "Print anything to the screen", + Long: `print is for printing anything back to the screen. + For many years people have printed back to the screen. + `, + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Print: " + strings.Join(args, " ")) + }, + } + + var cmdEcho = &cobra.Command{ + Use: "echo [string to echo]", + Short: "Echo anything to the screen", + Long: `echo is for echoing anything back. + Echo works a lot like print, except it has a child command. + `, + Run: func(cmd *cobra.Command, args []string) { + fmt.Println("Print: " + strings.Join(args, " ")) + }, + } + + var cmdTimes = &cobra.Command{ + Use: "times [# times] [string to echo]", + Short: "Echo anything to the screen more times", + Long: `echo things multiple times back to the user by providing + a count and a string.`, + Run: func(cmd *cobra.Command, args []string) { + for i := 0; i < echoTimes; i++ { + fmt.Println("Echo: " + strings.Join(args, " ")) + } + }, + } + + cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input") + + var rootCmd = &cobra.Command{Use: "app"} + rootCmd.AddCommand(cmdPrint, cmdEcho) + cmdEcho.AddCommand(cmdTimes) + rootCmd.Execute() +} +``` + +For a more complete example of a larger application, please checkout [Hugo](http://gohugo.io/). + +## The Help Command + +Cobra automatically adds a help command to your application when you have subcommands. +This will be called when a user runs 'app help'. Additionally, help will also +support all other commands as input. Say, for instance, you have a command called +'create' without any additional configuration; Cobra will work when 'app help +create' is called.

The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order: + +- `PersistentPreRun` +- `PreRun` +- `Run` +- `PostRun` +- `PersistentPostRun` + +An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`: + +```go +package main + +import ( + "fmt" + + "github.com/spf13/cobra" +) + +func main() { + + var rootCmd = &cobra.Command{ + Use: "root [sub]", + Short: "My root command", + PersistentPreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args) + }, + PreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PreRun with args: %v\n", args) + }, + Run: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd Run with args: %v\n", args) + }, + PostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PostRun with args: %v\n", args) + }, + PersistentPostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args) + }, + } + + var subCmd = &cobra.Command{ + Use: "sub [no options!]", + Short: "My subcommand", + PreRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PreRun with args: %v\n", args) + }, + Run: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd Run with args: %v\n", args) + }, + PostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PostRun with args: %v\n", args) + }, + PersistentPostRun: func(cmd *cobra.Command, args []string) { + fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args) + }, + } + + rootCmd.AddCommand(subCmd) + + rootCmd.SetArgs([]string{""}) + _ = rootCmd.Execute() + fmt.Print("\n") + rootCmd.SetArgs([]string{"sub", "arg1", "arg2"}) + _ = rootCmd.Execute() +} +``` + + +## Alternative Error Handling + +Cobra also has functions where the return signature is an error. This allows for errors to bubble up to the top, +providing a way to handle the errors in one location. The current list of functions that return an error is: + +* PersistentPreRunE +* PreRunE +* RunE +* PostRunE +* PersistentPostRunE + +If you would like to silence the default `error` and `usage` output in favor of your own, you can set `SilenceUsage` +and `SilenceErrors` to `false` on the command. A child command respects these flags if they are set on the parent +command. + +**Example Usage using RunE:** + +```go +package main + +import ( + "errors" + "log" + + "github.com/spf13/cobra" +) + +func main() { + var rootCmd = &cobra.Command{ + Use: "hugo", + Short: "Hugo is a very fast static site generator", + Long: `A Fast and Flexible Static Site Generator built with + love by spf13 and friends in Go. + Complete documentation is available at http://hugo.spf13.com`, + RunE: func(cmd *cobra.Command, args []string) error { + // Do Stuff Here + return errors.New("some random error") + }, + } + + if err := rootCmd.Execute(); err != nil { + log.Fatal(err) + } +} +``` + +## Suggestions when "unknown command" happens + +Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example: + +``` +$ hugo srever +Error: unknown command "srever" for "hugo" + +Did you mean this? + server + +Run 'hugo --help' for usage. +``` + +Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion. + +If you need to disable suggestions or tweak the string distance in your command, use: + +```go +command.DisableSuggestions = true +``` + +or + +```go +command.SuggestionsMinimumDistance = 1 +``` + +You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example: + +``` +$ kubectl remove +Error: unknown command "remove" for "kubectl" + +Did you mean this? + delete + +Run 'kubectl help' for usage. +``` + +## Generating Markdown-formatted documentation for your command + +Cobra can generate a Markdown-formatted document based on the subcommands, flags, etc. A simple example of how to do this for your command can be found in [Markdown Docs](doc/md_docs.md). + +## Generating man pages for your command + +Cobra can generate a man page based on the subcommands, flags, etc. A simple example of how to do this for your command can be found in [Man Docs](doc/man_docs.md). + +## Generating bash completions for your command + +Cobra can generate a bash-completion file. If you add more information to your command, these completions can be amazingly powerful and flexible. Read more about it in [Bash Completions](bash_completions.md). + +## Debugging + +Cobra provides a ‘DebugFlags’ method on a command which, when called, will print +out everything Cobra knows about the flags for each command. + +### Example + +```go +command.DebugFlags() +``` + +## Release Notes +* **0.9.0** June 17, 2014 + * flags can appears anywhere in the args (provided they are unambiguous) + * --help prints usage screen for app or command + * Prefix matching for commands + * Cleaner looking help and usage output + * Extensive test suite +* **0.8.0** Nov 5, 2013 + * Reworked interface to remove commander completely + * Command now primary structure + * No initialization needed + * Usage & Help templates & functions definable at any level + * Updated Readme +* **0.7.0** Sept 24, 2013 + * Needs more eyes + * Test suite + * Support for automatic error messages + * Support for help command + * Support for printing to any io.Writer instead of os.Stderr + * Support for persistent flags which cascade down tree + * Ready for integration into Hugo +* **0.1.0** Sept 3, 2013 + * Implement first draft + +## Extensions + +Libraries for extending Cobra: + +* [cmdns](https://github.com/gosuri/cmdns): Enables name spacing a command's immediate children.

Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods! + +## Have the completions code complete your 'nouns' + +In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like: + +```go +validArgs []string = { "pod", "node", "service", "replicationcontroller" } + +cmd := &cobra.Command{ + Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)", + Short: "Display one or many resources", + Long: get_long, + Example: get_example, + Run: func(cmd *cobra.Command, args []string) { + err := RunGet(f, out, cmd, args) + util.CheckErr(err) + }, + ValidArgs: validArgs, +} +``` + +Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like + +```bash +# kubectl get [tab][tab] +node pod replicationcontroller service +``` + +## Plural form and shortcuts for nouns + +If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`: + +```go` +argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" } + +cmd := &cobra.Command{ + ... + ValidArgs: validArgs, + ArgAliases: argAliases +} +``` + +The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by +the completion algorithm if entered manually, e.g. in: + +```bash +# kubectl get rc [tab][tab] +backend frontend database +``` + +Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns +in this example again instead of the replication controllers. + +## Mark flags as required + +Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab]. Marking a flag as 'Required' is incredibly easy. + +```go +cmd.MarkFlagRequired("pod") +cmd.MarkFlagRequired("container") +``` + +and you'll get something like + +```bash +# kubectl exec [tab][tab][tab] +-c --container= -p --pod= +``` + +# Specify valid filename extensions for flags that take a filename + +In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions. + +```go + annotations := []string{"json", "yaml", "yml"} + annotation := make(map[string][]string) + annotation[cobra.BashCompFilenameExt] = annotations + + flag := &pflag.Flag{ + Name: "filename", + Shorthand: "f", + Usage: usage, + Value: value, + DefValue: value.String(), + Annotations: annotation, + } + cmd.Flags().AddFlag(flag) +``` + +Now when you run a command with this filename flag you'll get something like + +```bash +# kubectl create -f +test/ example/ rpmbuild/ +hello.yml test.json +``` + +So while there are many other files in the CWD it only shows me subdirs and those with valid extensions. + +# Specifiy custom flag completion + +Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specifiy +a custom flag completion function with cobra.BashCompCustom: + +```go + annotation := make(map[string][]string) + annotation[cobra.BashCompFilenameExt] = []string{"__kubectl_get_namespaces"} + + flag := &pflag.Flag{ + Name: "namespace", + Usage: usage, + Annotations: annotation, + } + cmd.Flags().AddFlag(flag) +``` + +In addition add the `__handle_namespace_flag` implementation in the `BashCompletionFunction` +value, e.g.: + +```bash +__kubectl_get_namespaces() +{ + local template + template="{{ range .items }}{{ .metadata.name }} {{ end }}" + local kubectl_out + if kubectl_out=$(kubectl get -o template --template="${template}" namespace 2>/dev/null); then + COMPREPLY=( $( compgen -W "${kubectl_out}[*]" -- "$cur" ) ) + fi +} +``` diff --git a/vendor/github.com/spf13/cobra/cobra.go b/vendor/github.com/spf13/cobra/cobra.go new file mode 100644 index 0000000..b39c715 --- /dev/null +++ b/vendor/github.com/spf13/cobra/cobra.go @@ -0,0 +1,173 @@ +// Copyright © 2013 Steve Francia . +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +// Commands similar to git, go tools and other modern CLI tools +// inspired by go, go-Commander, gh and subcommand + +package cobra + +import ( + "fmt" + "io" + "reflect" + "strconv" + "strings" + "text/template" + "unicode" +) + +var templateFuncs = template.FuncMap{ + "trim": strings.TrimSpace, + "trimRightSpace": trimRightSpace, + "appendIfNotPresent": appendIfNotPresent, + "rpad": rpad, + "gt": Gt, + "eq": Eq, +} + +var initializers []func() + +// Automatic prefix matching can be a dangerous thing to automatically enable in CLI tools. +// Set this to true to enable it. +var EnablePrefixMatching = false + +// EnableCommandSorting controls sorting of the slice of commands, which is turned on by default. +// To disable sorting, set it to false. +var EnableCommandSorting = true + +// AddTemplateFunc adds a template function that's available to Usage and Help +// template generation. +func AddTemplateFunc(name string, tmplFunc interface{}) { + templateFuncs[name] = tmplFunc +} + +// AddTemplateFuncs adds multiple template functions availalble to Usage and +// Help template generation. +func AddTemplateFuncs(tmplFuncs template.FuncMap) { + for k, v := range tmplFuncs { + templateFuncs[k] = v + } +} + +// OnInitialize takes a series of func() arguments and appends them to a slice of func(). +func OnInitialize(y ...func()) { + initializers = append(initializers, y...) +} + +// Gt takes two types and checks whether the first type is greater than the second.

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("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. + +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") +``` + +## 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
