Shell Auto Completion
=====================

tests/test.py
-------------

### Bash

Short version: copy this into your .profile file:

    _cfa_test() (
        (case $3 in
        (--continue|--debug|--install|--timout-with-gdb)
            echo yes no;;
        (--arch)
            echo x86 x64;;
        (-I|--include|-E|--exclude)
            $1 --list-comp | tr ' ' '\n' | sed -e 's@/[^/]\+$@/@;t;d';;
        (*)
            $1 --list-comp;;
        esac) | grep -Ewoe "$2[^[:space:]]*"
    )
    complete -C _cfa_test tests/test.py

The long version includes reading the bash manual, check for the complete
built-in and readline programmable completion for details on how these
commands are used. You can copy-paste the results directily into your
terminal to test them or put them in one of the initalization files so they
are loaded at start-up.

This particular script does not handle the comma seperated options.

### Zsh

1 - Add the following somewhere:
    #compdef test.py

    _test_py() {
        local -a options
        options=$($words[1] --list-comp)
        _alternative "files:filenames:($options)"
    }

    _test_py "$@"

2 - Add the path to that file to the "fpath" environment variable.

3 - In ~/.zshrc add
    autoload -U compinit
    compinit

*How it works:* I don't know ;P
