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. - -[More about cobra.Command](https://godoc.org/github.com/spf13/cobra#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/spf13/pflag), a fork of the flag standard library -which maintains the same interface while adding POSIX compliance. - -# Installing -Using Cobra is easy. First, use `go get` to install the latest version -of the library. This command will install the `cobra` generator executable -along with the library and its dependencies: - - go get -u github.com/spf13/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: initializing Cobra. - -```go -package main - -import ( - "{pathToYourApp}/cmd" -) - -func main() { - cmd.Execute() -} -``` - -## 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. - -[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it. - -## Using the Cobra Library - -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 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 - }, -} - -func Execute() { - if err := rootCmd.Execute(); err != nil { - fmt.Fprintln(os.Stderr, err) - os.Exit(1) - } -} -``` - -You will additionally define flags and handle configuration in your init() function. - -For example cmd/root.go: - -```go -package cmd - -import ( - "fmt" - "os" - - homedir "github.com/mitchellh/go-homedir" - "github.com/spf13/cobra" - "github.com/spf13/viper" -) - -var ( - // Used for flags. - cfgFile string - userLicense string - - rootCmd = &cobra.Command{ - Use: "cobra", - Short: "A generator for Cobra based Applications", - Long: `Cobra is a CLI library for Go that empowers applications. -This application is a tool to generate the needed files -to quickly create a Cobra application.`, - } -) - -// Execute executes the root command. -func Execute() error { - return rootCmd.Execute() -} - -func init() { - cobra.OnInitialize(initConfig) - - rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)") - rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution") - rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project") - rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration") - viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author")) - viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper")) - viper.SetDefault("author", "NAME HERE ") - viper.SetDefault("license", "apache") - - rootCmd.AddCommand(addCmd) - rootCmd.AddCommand(initCmd) -} - -func er(msg interface{}) { - fmt.Println("Error:", msg) - os.Exit(1) -} - -func initConfig() { - if cfgFile != "" { - // Use config file from the flag. - viper.SetConfigFile(cfgFile) - } else { - // Find home directory. - home, err := homedir.Dir() - if err != nil { - er(err) - } - - // Search config in home directory with name ".cobra" (without extension). - viper.AddConfigPath(home) - viper.SetConfigName(".cobra") - } - - viper.AutomaticEnv() - - if err := viper.ReadInConfig(); err == nil { - fmt.Println("Using config file:", viper.ConfigFileUsed()) - } -} -``` - -### 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() { - cmd.Execute() -} -``` - -### 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 ( - "fmt" - - "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") - }, -} -``` - -### Returning and handling errors - -If you wish to return an error to the caller of a command, `RunE` can be used. - -```go -package cmd - -import ( - "fmt" - - "github.com/spf13/cobra" -) - -func init() { - rootCmd.AddCommand(tryCmd) -} - -var tryCmd = &cobra.Command{ - Use: "try", - Short: "Try and possibly fail at something", - RunE: func(cmd *cobra.Command, args []string) error { - if err := someFunc(); err != nil { - return err - } - return nil - }, -} -``` - -The error can then be caught at the execute function call. - -## 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 -localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from") -``` - -### Local Flag on Parent Commands - -By default Cobra only parses local flags on the target command, any local flags on -parent commands are ignored. By enabling `Command.TraverseChildren` Cobra will -parse local flags on each command before executing the target command. - -```go -command := cobra.Command{ - Use: "print [OPTIONS] [COMMANDS]", - TraverseChildren: true, -} -``` - -### Bind Flags with Config - -You can also bind your flags with [viper](https://github.com/spf13/viper): -```go -var author string - -func init() { - rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution") - viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author")) -} -``` - -In this example the persistent flag `author` is bound with `viper`. -**Note**, that the variable `author` will not be set to the value from config, -when the `--author` flag is not provided by user. - -More in [viper documentation](https://github.com/spf13/viper#working-with-flags). - -### Required flags - -Flags are optional by default. If instead you wish your command to report an error -when a flag has not been set, mark it as required: -```go -rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)") -rootCmd.MarkFlagRequired("region") -``` - -Or, for persistent flags: -```go -rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)") -rootCmd.MarkPersistentFlagRequired("region") -``` - -## Positional and Custom Arguments - -Validation of positional arguments can be specified using the `Args` field -of `Command`. - -The following validators are built in: - -- `NoArgs` - the command will report an error if there are any positional args. -- `ArbitraryArgs` - the command will accept any args. -- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`. -- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args. -- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args. -- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args. -- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command` -- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args. - -An example of setting the custom validator: - -```go -var cmd = &cobra.Command{ - Short: "hello", - Args: func(cmd *cobra.Command, args []string) error { - if len(args) < 1 { - return errors.New("requires a color argument") - } - if myapp.IsValidColor(args[0]) { - return nil - } - return fmt.Errorf("invalid color specified: %s", args[0]) - }, - Run: func(cmd *cobra.Command, args []string) { - fmt.Println("Hello, World!") - }, -} -``` - -## 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.`, - Args: cobra.MinimumNArgs(1), - 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.`, - Args: cobra.MinimumNArgs(1), - Run: func(cmd *cobra.Command, args []string) { - fmt.Println("Echo: " + strings.Join(args, " ")) - }, - } - - var cmdTimes = &cobra.Command{ - Use: "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.`, - Args: cobra.MinimumNArgs(1), - 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/). - -## 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. Every command will automatically have the '--help' flag added. - -### Example - -The following output is automatically generated by Cobra. Nothing beyond the -command and flag definitions are needed. - - $ cobra help - - Cobra is a CLI library for Go that empowers applications. - This application is a tool to generate the needed files - to quickly create a Cobra application. - - Usage: - cobra [command] - - Available Commands: - add Add a command to a Cobra Application - help Help about any command - init Initialize a Cobra Application - - Flags: - -a, --author string author name for copyright attribution (default "YOUR NAME") - --config string config file (default is $HOME/.cobra.yaml) - -h, --help help for cobra - -l, --license string name of license for the project - --viper use Viper for configuration (default true) - - Use "cobra [command] --help" for more information about a command. - - -Help is just a command like any other. There is no special logic or behavior -around it. In fact, you can provide your own if you want. - -### Defining your own help - -You can provide your own Help command or your own template for the default command to use -with following functions: - -```go -cmd.SetHelpCommand(cmd *Command) -cmd.SetHelpFunc(f func(*Command, []string)) -cmd.SetHelpTemplate(s string) -``` - -The latter two will also apply to any children commands. - -## Usage Message - -When the user provides an invalid flag or invalid command, Cobra responds by -showing the user the 'usage'. - -### Example -You may recognize this from the help above. That's because the default help -embeds the usage as part of its output. - - $ cobra --invalid - Error: unknown flag: --invalid - Usage: - cobra [command] - - Available Commands: - add Add a command to a Cobra Application - help Help about any command - init Initialize a Cobra Application - - Flags: - -a, --author string author name for copyright attribution (default "YOUR NAME") - --config string config file (default is $HOME/.cobra.yaml) - -h, --help help for cobra - -l, --license string name of license for the project - --viper use Viper for configuration (default true) - - Use "cobra [command] --help" for more information about a command. - -### Defining your own usage -You can provide your own usage function or template for Cobra to use. -Like help, the function and template are overridable through public methods: - -```go -cmd.SetUsageFunc(f func(*Command) error) -cmd.SetUsageTemplate(s string) -``` - -## Version Flag - -Cobra adds a top-level '--version' flag if the Version field is set on the root command. -Running an application with the '--version' flag will print the version to stdout using -the version template. The template can be customized using the -`cmd.SetVersionTemplate(s string)` function. - -## PreRun and PostRun Hooks - -It is possible to run functions before or after the main `Run` function of your command. 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.Println() - rootCmd.SetArgs([]string{"sub", "arg1", "arg2"}) - rootCmd.Execute() -} -``` - -Output: -``` -Inside rootCmd PersistentPreRun with args: [] -Inside rootCmd PreRun with args: [] -Inside rootCmd Run with args: [] -Inside rootCmd PostRun with args: [] -Inside rootCmd PersistentPostRun with args: [] - -Inside rootCmd PersistentPreRun with args: [arg1 arg2] -Inside subCmd PreRun with args: [arg1 arg2] -Inside subCmd Run with args: [arg1 arg2] -Inside subCmd PostRun with args: [arg1 arg2] -Inside subCmd PersistentPostRun with args: [arg1 arg2] -``` - -## 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 documentation for your command - -Cobra can generate documentation based on subcommands, flags, etc. Read more about it in the [docs generation documentation](doc/README.md). - -## Generating shell completions - -Cobra can generate a shell-completion file for the following shells: Bash, Zsh, Fish, Powershell. If you add more information to your commands, these completions can be amazingly powerful and flexible. Read more about it in [Shell Completions](shell_completions.md). - -# License - -Cobra is released under the Apache 2.0 license.

However, you can make your completions much more powerful by providing information to complete your program's nouns and flag values. - -## Completion of nouns - -### Static completion of nouns - -Cobra allows you to provide a pre-defined list of completion choices for your nouns using the `ValidArgs` field. -For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. -Some 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` field on the `get` sub-command. Doing so will give results like: - -```bash -$ kubectl get [tab][tab] -node pod replicationcontroller service -``` - -#### Aliases for nouns - -If your nouns have 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 not know to show the list of -replication controllers following `rc`. - -### Dynamic completion of nouns - -In some cases it is not possible to provide a list of completions in advance. Instead, the list of completions must be determined at execution-time. In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both. -Simplified code from `helm status` looks like: - -```go -cmd := &cobra.Command{ - Use: "status RELEASE_NAME", - Short: "Display the status of the named release", - Long: status_long, - RunE: func(cmd *cobra.Command, args []string) { - RunGet(args[0]) - }, - ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - if len(args) != 0 { - return nil, cobra.ShellCompDirectiveNoFileComp - } - return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp - }, -} -``` -Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster. -Notice we put the `ValidArgsFunction` on the `status` sub-command. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like: - -```bash -$ helm status [tab][tab] -harbor notary rook thanos -``` -You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp` -```go -// Indicates that the shell will perform its default behavior after completions -// have been provided (this implies none of the other directives). -ShellCompDirectiveDefault - -// Indicates an error occurred and completions should be ignored. -ShellCompDirectiveError - -// Indicates that the shell should not add a space after the completion, -// even if there is a single completion provided. -ShellCompDirectiveNoSpace - -// Indicates that the shell should not provide file completion even when -// no completion is provided. -ShellCompDirectiveNoFileComp - -// Indicates that the returned completions should be used as file extension filters. -// For example, to complete only files of the form *.json or *.yaml: -// return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt -// For flags, using MarkFlagFilename() and MarkPersistentFlagFilename() -// is a shortcut to using this directive explicitly. -// -ShellCompDirectiveFilterFileExt - -// Indicates that only directory names should be provided in file completion. -// For example: -// return nil, ShellCompDirectiveFilterDirs -// For flags, using MarkFlagDirname() is a shortcut to using this directive explicitly. -// -// To request directory names within another directory, the returned completions -// should specify a single directory name within which to search. For example, -// to complete directories within "themes/": -// return []string{"themes"}, ShellCompDirectiveFilterDirs -// -ShellCompDirectiveFilterDirs -``` - -***Note***: When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function. - -#### Debugging - -Cobra achieves dynamic completion through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly: -```bash -$ helm __complete status har -harbor -:4 -Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr -``` -***Important:*** If the noun to complete is empty (when the user has not yet typed any letters of that noun), you must pass an empty parameter to the `__complete` command: -```bash -$ helm __complete status "" -harbor -notary -rook -thanos -:4 -Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr -``` -Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code: -```go -// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE -// is set to a file path) and optionally prints to stderr. -cobra.CompDebug(msg string, printToStdErr bool) { -cobra.CompDebugln(msg string, printToStdErr bool) - -// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE -// is set to a file path) and to stderr. -cobra.CompError(msg string) -cobra.CompErrorln(msg string) -``` -***Important:*** You should **not** leave traces that print directly to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned above. - -## Completions for flags - -### Mark flags as required - -Most of the time completions will only show sub-commands. But if a flag is required to make a sub-command work, you probably want it to show up when the user types [tab][tab]. You can mark a flag as 'Required' like so: - -```go -cmd.MarkFlagRequired("pod") -cmd.MarkFlagRequired("container") -``` - -and you'll get something like - -```bash -$ kubectl exec [tab][tab] --c --container= -p --pod= -``` - -### Specify dynamic flag completion - -As for nouns, Cobra provides a way of defining dynamic completion of flags. To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function using the `command.RegisterFlagCompletionFunc()` function. - -```go -flagName := "output" -cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault -}) -``` -Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated. In our example this dynamic completion will give results like so: - -```bash -$ helm status --output [tab][tab] -json table yaml -``` - -#### Debugging - -You can also easily debug your Go completion code for flags: -```bash -$ helm __complete status --output "" -json -table -yaml -:4 -Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr -``` -***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned further above. - -### Specify valid filename extensions for flags that take a filename - -To limit completions of flag values to file names with certain extensions you can either use the different `MarkFlagFilename()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterFileExt`, like so: -```go -flagName := "output" -cmd.MarkFlagFilename(flagName, "yaml", "json") -``` -or -```go -flagName := "output" -cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt}) -``` - -### Limit flag completions to directory names - -To limit completions of flag values to directory names you can either use the `MarkFlagDirname()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs`, like so: -```go -flagName := "output" -cmd.MarkFlagDirname(flagName) -``` -or -```go -flagName := "output" -cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - return nil, cobra.ShellCompDirectiveFilterDirs -}) -``` -To limit completions of flag values to directory names *within another directory* you can use a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs` like so: -```go -flagName := "output" -cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - return []string{"themes"}, cobra.ShellCompDirectiveFilterDirs -}) -``` -### Descriptions for completions - -Both `zsh` and `fish` allow for descriptions to annotate completion choices. For commands and flags, Cobra will provide the descriptions automatically, based on usage information. For example, using zsh: -``` -$ helm s[tab] -search -- search for a keyword in charts -show -- show information of a chart -status -- displays the status of the named release -``` -while using fish: -``` -$ helm s[tab] -search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release) -``` - -Cobra allows you to add annotations to your own completions. Simply add the annotation text after each completion, following a `\t` separator. This technique applies to completions returned by `ValidArgs`, `ValidArgsFunction` and `RegisterFlagCompletionFunc()`. For example: -```go -ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { - return []string{"harbor\tAn image registry", "thanos\tLong-term metrics"}, cobra.ShellCompDirectiveNoFileComp -}} -``` -or -```go -ValidArgs: []string{"bash\tCompletions for bash", "zsh\tCompletions for zsh"} -``` -## Bash completions - -### Dependencies - -The bash completion script generated by Cobra requires the `bash_completion` package. You should update the help text of your completion command to show how to install the `bash_completion` package ([Kubectl docs](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion)) - -### Aliases - -You can also configure `bash` aliases for your program and they will also support completions. - -```bash -alias aliasname=origcommand -complete -o default -F __start_origcommand aliasname - -# and now when you run `aliasname` completion will make -# suggestions as it did for `origcommand`. - -$ aliasname -completion firstcommand secondcommand -``` -### Bash legacy dynamic completions - -For backwards-compatibility, Cobra still supports its bash legacy dynamic completion solution. -Please refer to [Bash Completions](bash_completions.md) for details. - -## Zsh completions - -Cobra supports native Zsh completion generated from the root `cobra.Command`. -The generated completion script should be put somewhere in your `$fpath` and be named -`_`. You will need to start a new shell for the completions to become available. - -Zsh supports descriptions for completions. Cobra will provide the description automatically, -based on usage information. Cobra provides a way to completely disable such descriptions by -using `GenZshCompletionNoDesc()` or `GenZshCompletionFileNoDesc()`. You can choose to make -this a configurable option to your users. -``` -# With descriptions -$ helm s[tab] -search -- search for a keyword in charts -show -- show information of a chart -status -- displays the status of the named release - -# Without descriptions -$ helm s[tab] -search show status -``` -*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`. - -### Limitations - -* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `zsh` (including the use of the `BashCompCustom` flag annotation). - * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`). -* The function `MarkFlagCustom()` is not supported and will be ignored for `zsh`. - * You should instead use `RegisterFlagCompletionFunc()`. - -### Zsh completions standardization - -Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced. -Please refer to [Zsh Completions](zsh_completions.md) for details. - -## Fish completions - -Cobra supports native Fish completions generated from the root `cobra.Command`. You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users. -``` -# With descriptions -$ helm s[tab] -search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release) - -# Without descriptions -$ helm s[tab] -search show status -``` -*Note*: Because of backwards-compatibility requirements, we were forced to have a different API to disable completion descriptions between `Zsh` and `Fish`. - -### Limitations - -* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `fish` (including the use of the `BashCompCustom` flag annotation). - * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`). -* The function `MarkFlagCustom()` is not supported and will be ignored for `fish`. - * You should instead use `RegisterFlagCompletionFunc()`. -* The following flag completion annotations are not supported and will be ignored for `fish`: - * `BashCompFilenameExt` (filtering by file extension) - * `BashCompSubdirsInDir` (filtering by directory) -* The functions corresponding to the above annotations are consequently not supported and will be ignored for `fish`: - * `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension) - * `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory) -* Similarly, the following completion directives are not supported and will be ignored for `fish`: - * `ShellCompDirectiveFilterFileExt` (filtering by file extension) - * `ShellCompDirectiveFilterDirs` (filtering by directory) - -## PowerShell completions - -Please refer to [PowerShell Completions](powershell_completions.md) for details. diff --git a/vendor/github.com/spf13/cobra/zsh_completions.go b/vendor/github.com/spf13/cobra/zsh_completions.go deleted file mode 100644 index 92a70394a..000000000 --- a/vendor/github.com/spf13/cobra/zsh_completions.go +++ /dev/null @@ -1,240 +0,0 @@ -package cobra - -import ( - "bytes" - "fmt" - "io" - "os" -) - -// GenZshCompletionFile generates zsh completion file including descriptions. -func (c *Command) GenZshCompletionFile(filename string) error { - return c.genZshCompletionFile(filename, true) -} - -// GenZshCompletion generates zsh completion file including descriptions -// and writes it to the passed writer. -func (c *Command) GenZshCompletion(w io.Writer) error { - return c.genZshCompletion(w, true) -} - -// GenZshCompletionFileNoDesc generates zsh completion file without descriptions. -func (c *Command) GenZshCompletionFileNoDesc(filename string) error { - return c.genZshCompletionFile(filename, false) -} - -// GenZshCompletionNoDesc generates zsh completion file without descriptions -// and writes it to the passed writer. -func (c *Command) GenZshCompletionNoDesc(w io.Writer) error { - return c.genZshCompletion(w, false) -} - -// MarkZshCompPositionalArgumentFile only worked for zsh and its behavior was -// not consistent with Bash completion.
