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.

# Generating Yaml Docs For Your Own cobra.Command
Generating yaml files from a cobra command is incredibly easy. An example is as follows:
```go
package main
import (
"github.com/spf13/cobra"
"github.com/spf13/cobra/doc"
)
func main() {
cmd := &cobra.Command{
Use: "test",
Short: "my test program",
}
doc.GenYamlTree(cmd, "/tmp")
}
```
That will get you a Yaml document `/tmp/test.yaml`
## Generate yaml docs for the entire command tree
This program can actually generate docs for the kubectl command in the kubernetes project
```go
package main
import (
"io/ioutil"
"os"
"k8s.io/kubernetes/pkg/kubectl/cmd"
cmdutil "k8s.io/kubernetes/pkg/kubectl/cmd/util"
"github.com/spf13/cobra/doc"
)
func main() {
kubectl := cmd.NewKubectlCommand(cmdutil.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
doc.GenYamlTree(kubectl, "./")
}
```
This will generate a whole series of files, one for each command in the tree, in the directory specified (in this case "./")
## Generate yaml docs for a single command
You may wish to have more control over the output, or only generate for a single command, instead of the entire command tree. If this is the case you may prefer to `GenYaml` instead of `GenYamlTree`
```go
out := new(bytes.Buffer)
doc.GenYaml(cmd, out)
```
This will write the yaml doc for ONLY "cmd" into the out, buffer.
## Customize the output
Both `GenYaml` and `GenYamlTree` have alternate versions with callbacks to get some control of the output:
```go
func GenYamlTreeCustom(cmd *Command, dir string, filePrepender, linkHandler func(string) string) error {
//...
}
```
```go
func GenYamlCustom(cmd *Command, out *bytes.Buffer, linkHandler func(string) string) error {
//...
}
```
The `filePrepender` will prepend the return value given the full filepath to the rendered Yaml file. A common use case is to add front matter to use the generated documentation with [Hugo](http://gohugo.io/):
```go
const fmTemplate = `---
date: %s
title: "%s"
slug: %s
url: %s
---
`
filePrepender := func(filename string) string {
now := time.Now().Format(time.RFC3339)
name := filepath.Base(filename)
base := strings.TrimSuffix(name, path.Ext(name))
url := "/commands/" + strings.ToLower(base) + "/"
return fmt.Sprintf(fmTemplate, now, strings.Replace(base, "_", " ", -1), base, url)
}
```
The `linkHandler` can be used to customize the rendered internal links to the commands, given a filename:
```go
linkHandler := func(name string) string {
base := strings.TrimSuffix(name, path.Ext(name))
return "/commands/" + strings.ToLower(base) + "/"
}
```
