Cobra is both a library for creating powerful modern CLI applications as well as a program to generate applications and command files.
|
||||
|
||||
Many of the most widely used Go projects are built using Cobra, such as:

### 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.

- [ReStructured Text](doc/rest_docs.md)

## Generating shell completions
|
||||
|
||||
## 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
