'''
To add completion for a new shell, you need to:
1) Add an entry to completion scripts for your shell, this is
a simple function that calls kitty's completion code and passes the
results to the shell's completion system. This can be output by
`kitty +complete setup shell_name` and its output goes into
your shell's rc file.
2) Add an input_parser function, this takes the input from
the shell for the text being completed and returns a list of words
and a boolean indicating if we are on a new word or not. This
is passed to kitty's completion system.
3) An output_serializer function that is responsible for
taking the results from kitty's completion system and converting
them into something your shell will understand.
