Generating Fish Completions for your own cobra.Command

Cobra supports native Fish completions generated from the root cobra.Command. You can use the command.GenFishCompletion() or command.GenFishCompletionFile() functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.

Limitations

• Custom completions implemented using the ValidArgsFunction and RegisterFlagCompletionFunc() are supported automatically but the ones implemented in Bash scripting are not.
