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 *Arrary and *Slice types supports multiple specifications (with or without argument depending on the specific type).

What's not yet Supported

• Positional argument completion are not supported yet.
• 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 :)
