Cobra is a library for creating powerful modern CLI applications.
Cobra is used in many Go projects such as [Kubernetes](https://kubernetes.io/),
[Hugo](https://gohugo.io), and [Github CLI](https://github.com/cli/cli) to
[Hugo](https://gohugo.io), and [GitHub CLI](https://github.com/cli/cli) to

* Global, local and cascading flags
* Intelligent suggestions (`app srver`... did you mean `app server`?)
* Automatic help generation for commands and flags
* Grouping help for subcommands
* Automatic help flag recognition of `-h`, `--help`, etc.
* Automatically generated shell autocomplete for your application (bash, zsh, fish, powershell)
* Automatically generated man pages for your application

intuitively know how to interact with them.
The pattern to follow is
`APPNAME VERB NOUN --ADJECTIVE.`
`APPNAME VERB NOUN --ADJECTIVE`
or
`APPNAME COMMAND ARG --FLAG`
`APPNAME COMMAND ARG --FLAG`.
A few good real world examples may better illustrate this point.

You can also configure `powershell` aliases for your program and they will also support completions.

$ sal aliasname origcommand
$ Register-ArgumentCompleter -CommandName 'aliasname' -ScriptBlock $__origcommandCompleterBlock
# and now when you run `aliasname` completion will make
# suggestions as it did for `origcommand`.

## Positional and Custom Arguments
Validation of positional arguments can be specified using the `Args` field of `Command`.
If `Args` is undefined or `nil`, it defaults to `ArbitraryArgs`.
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.
- `MatchAll(pargs ...PositionalArgs)` - enables combining existing checks with arbitrary other checks (e.g. you want to check the ExactArgs length along with other qualities).
- Number of arguments:
- `NoArgs` - report an error if there are any positional args.
- `ArbitraryArgs` - accept any number of args.
- `MinimumNArgs(int)` - report an error if less than N positional args are provided.
- `MaximumNArgs(int)` - report an error if more than N positional args are provided.
- `ExactArgs(int)` - report an error if there are not exactly N positional args.
- `RangeArgs(min, max)` - report an error if the number of args is not between `min` and `max`.
- Content of the arguments:
- `OnlyValidArgs` - report an error if there are any positional args not specified in the `ValidArgs` field of `Command`, which can optionally be set to a list of valid values for positional args.
An example of setting the custom validator:
If `Args` is undefined or `nil`, it defaults to `ArbitraryArgs`.
Moreover, `MatchAll(pargs ...PositionalArgs)` enables combining existing checks with arbitrary other checks.
For instance, if you want to 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`, you can call `MatchAll` on `ExactArgs` and `OnlyValidArgs`, as
shown below:
```go
var cmd = &cobra.Command{
Short: "hello",
Args: MatchAll(ExactArgs(2), OnlyValidArgs),
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Hello, World!")
},
}
```
It is possible to set any custom validator that satisfies `func(cmd *cobra.Command, args []string) error`.
For example:
```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")
// Optionally run one of the validators provided by cobra
if err := cobra.MinimumNArgs(1)(cmd, args); err != nil {
return err
}
// Run the custom validation logic
if myapp.IsValidColor(args[0]) {
return nil

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.
### Grouping commands in help
Cobra supports grouping of available commands in the help output. To group commands, each group must be explicitly
defined using `AddGroup()` on the parent command. Then a subcommand can be added to a group using the `GroupID` element
of that subcommand. The groups will appear in the help output in the same order as they are defined using different
calls to `AddGroup()`. If you use the generated `help` or `completion` commands, you can set their group ids using
`SetHelpCommandGroupId()` and `SetCompletionCommandGroupId()` on the root command, respectively.
### Defining your own help
