CLI.Completion.App

bash

(Fn [(Ref CLI.App a), (Ref String b)] String)

                        (bash app prog)
                    

generates a bash completion script for the App app, to be installed for the program called prog.

The first word completes to the registered subcommand names (plus --help/-h); after a subcommand has been given, completion continues with that subcommand’s own flags and declared value sets, exactly as bash does for a single Parser.

The script uses mapfile, so it needs bash 4 or newer.

fish

(Fn [(Ref CLI.App a), (Ref String b)] String)

                        (fish app prog)
                    

generates a fish completion script for the App app, to be installed for the program called prog.

The first word completes to the registered subcommand names, each shown with its parser’s description, and to nothing else; once a subcommand has been given, that subcommand’s own flags and declared value sets complete, exactly as fish does for a single Parser.

zsh

(Fn [(Ref CLI.App a), (Ref String b)] String)

                        (zsh app prog)
                    

generates a zsh completion script for the App app, to be installed for the program called prog.

The first word completes to the registered subcommand names, each shown with its parser’s description; after a subcommand has been given, completion continues with that subcommand’s own flags and declared value sets, exactly as zsh does for a single Parser.
