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/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.Println(err) - os.Exit(1) - } -} -``` - -You will additionally define flags and handle configuration in your init() function. - -For example cmd/root.go: - -```go -import ( - "fmt" - "os" - - homedir "github.com/mitchellh/go-homedir" - "github.com/spf13/cobra" - "github.com/spf13/viper" -) - -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 <EMAIL ADDRESS>") - viper.SetDefault("license", "apache") -} - -func initConfig() { - // Don't forget to read config either from cfgFile or from home directory! - if cfgFile != "" { - // Use config file from the flag. - viper.SetConfigFile(cfgFile) - } else { - // Find home directory. - home, err := homedir.Dir() - if err != nil { - fmt.Println(err) - os.Exit(1) - } - - // Search config in home directory with name ".cobra" (without extension). - viper.AddConfigPath(home) - viper.SetConfigName(".cobra") - } - - if err := viper.ReadInConfig(); err != nil { - fmt.Println("Can't read config:", err) - os.Exit(1) - } -} -``` - -### 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") - }, -} -``` - -## 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") -``` - -## 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("Print: " + 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. in the following formats: - -- [Markdown](doc/md_docs.md) -- [ReStructured Text](doc/rest_docs.md) -- [Man Page](doc/man_docs.md) - -## Generating bash completions - -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). - -## Generating zsh completions - -Cobra can generate zsh-completion file. Read more about it in -[Zsh Completions](zsh_completions.md). - -# Contributing - -1. Fork it -2. Download your fork to your PC (`git clone https://github.com/your_username/cobra && cd cobra`) -3.

If you make additional annotations to your code, you can get even more intelligent and flexible behavior. - -## Creating your own custom functions - -Some more actual code that works in kubernetes: - -```bash -const ( - bash_completion_func = `__kubectl_parse_get() -{ - local kubectl_output out - if kubectl_output=$(kubectl get --no-headers "$1" 2>/dev/null); then - out=($(echo "${kubectl_output}" | awk '{print $1}')) - COMPREPLY=( $( compgen -W "${out[*]}" -- "$cur" ) ) - fi -} - -__kubectl_get_resource() -{ - if [[ ${#nouns[@]} -eq 0 ]]; then - return 1 - fi - __kubectl_parse_get ${nouns[${#nouns[@]} -1]} - if [[ $? -eq 0 ]]; then - return 0 - fi -} - -__kubectl_custom_func() { - case ${last_command} in - kubectl_get | kubectl_describe | kubectl_delete | kubectl_stop) - __kubectl_get_resource - return - ;; - *) - ;; - esac -} -`) -``` - -And then I set that in my command definition: - -```go -cmds := &cobra.Command{ - Use: "kubectl", - Short: "kubectl controls the Kubernetes cluster manager", - Long: `kubectl controls the Kubernetes cluster manager. - -Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`, - Run: runHelp, - BashCompletionFunction: bash_completion_func, -} -``` - -The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`__<command-use>_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 `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_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. - -# Specify custom flag completion - -Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify -a custom flag completion function with cobra.BashCompCustom: - -```go - annotation := make(map[string][]string) - annotation[cobra.BashCompCustom] = []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}[*]" -- "$cur" ) ) - fi -} -``` -# Using bash aliases for commands - -You can also configure the `bash aliases` for the commands and they will also support completions. - -```bash -alias aliasname=origcommand -complete -o default -F __start_origcommand aliasname - -# and now when you run `aliasname` completion will make -# suggestions as it did for `origcommand`. - -$) aliasname <tab><tab> -completion firstcommand secondcommand -``` diff --git a/vendor/github.com/spf13/cobra/cobra.go b/vendor/github.com/spf13/cobra/cobra.go deleted file mode 100644 index 6505c070..00000000 --- a/vendor/github.com/spf13/cobra/cobra.go +++ /dev/null @@ -1,207 +0,0 @@ -// Copyright © 2013 Steve Francia <spf@spf13.com>. -// -// 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" - "time" - "unicode" -) - -var templateFuncs = template.FuncMap{ - "trim": strings.TrimSpace, - "trimRightSpace": trimRightSpace, - "trimTrailingWhitespaces": trimRightSpace, - "appendIfNotPresent": appendIfNotPresent, - "rpad": rpad, - "gt": Gt, - "eq": Eq, -} - -var initializers []func() - -// EnablePrefixMatching allows to set automatic prefix matching.
