# Generating Bash Completions For Your Own cobra.Command
If you are using the generator you can create a completion command by running
```bash
cobra add completion
```
Update the help text show how to install the bash_completion Linux show here [Kubectl docs show mac options](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion)
Writing the shell script to stdout allows the most flexible use.
```go
// completionCmd represents the completion command
var completionCmd = &cobra.Command{
Use: "completion",
Short: "Generates bash completion scripts",
Long: `To load completion run
. <(bitbucket completion)
To configure your bash shell to load completions for each session add to your bashrc
# ~/.bashrc or ~/.profile
. <(bitbucket completion)
`,
Run: func(cmd *cobra.Command, args []string) {
rootCmd.GenBashCompletion(os.Stdout);
},
}
```
**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script
## Example from kubectl
Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
```go
package main
import (
"io/ioutil"
"os"
"io/ioutil"
"os"
"github.com/GoogleCloudPlatform/kubernetes/pkg/kubectl/cmd"
"k8s.io/kubernetes/pkg/kubectl/cmd"
"k8s.io/kubernetes/pkg/kubectl/cmd/util"
)
func main() {
kubectl := cmd.NewFactory(nil).NewKubectlCommand(os.Stdin, ioutil.Discard, ioutil.Discard)
kubectl.GenBashCompletionFile("out.sh")
kubectl := cmd.NewKubectlCommand(util.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
kubectl.GenBashCompletionFile("out.sh")
}
```
That will get you completions of subcommands and flags. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.

The `BashCompletionFunction` option is really only valid/useful on the root command. 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!

# Generating PowerShell Completions For Your Own cobra.Command
Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
# What's supported
- Completion for subcommands using their `.Short` description
- Completion for non-hidden flags using their `.Name` and `.Shorthand`
# What's not yet supported
- Command aliases
- Required, filename or custom flags (they will work like normal flags)
- Custom completion scripts

## Generating Zsh Completion for your cobra.Command
Cobra supports native Zsh completion generated from the root `cobra.Command`.
The generated completion script should be put somewhere in your `$fpath` named
`_<YOUR COMMAND>`.
### What's Supported
* Completion for all non-hidden subcommands using their `.Short` description.
* Completion for all non-hidden flags using the following rules:
* Filename completion works by marking the flag with `cmd.MarkFlagFilename...`
family of commands.
* The requirement for argument to the flag is decided by the `.NoOptDefVal`
flag value - if it's empty then completion will expect an argument.
* Flags of one of the various `*Array` and `*Slice` types supports multiple
specifications (with or without argument depending on the specific type).
* Completion of positional arguments using the following rules:
* Argument position for all options below starts at `1`. If argument position
`0` is requested it will raise an error.
* Use `command.MarkZshCompPositionalArgumentFile` to complete filenames. Glob
patterns (e.g. `"*.log"`) are optional - if not specified it will offer to
complete all file types.
* Use `command.MarkZshCompPositionalArgumentWords` to offer specific words for
completion. At least one word is required.
* It's possible to specify completion for some arguments and leave some
unspecified (e.g. offer words for second argument but nothing for first
argument). This will cause no completion for first argument but words
completion for second argument.
* If no argument completion was specified for 1st argument (but optionally was
specified for 2nd) and the command has `ValidArgs` it will be used as
completion options for 1st argument.
* Argument completions only offered for commands with no subcommands.
### What's not yet Supported
* Custom completion scripts are not supported yet (We should probably create zsh
specific one, doesn't make sense to re-use the bash one as the functions will
be different).
* Whatever other feature you're looking for and doesn't exist :)

## Disable sorting of flags
`pflag` allows you to disable sorting of flags for help and usage message.
**Example**:
```go
flags.BoolP("verbose", "v", false, "verbose output")
flags.String("coolflag", "yeaah", "it's really cool flag")
flags.Int("usefulflag", 777, "sometimes it's very useful")
flags.SortFlags = false
flags.PrintDefaults()
```
**Output**:
```
-v, --verbose verbose output
--coolflag string it's really cool flag (default "yeaah")
--usefulflag int sometimes it's very useful (default 777)
```
## 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`).
