giga-add (play on giga chad) is an interactive wrapper for the git add command which allows you to quickly stage or unstage changes on a per-file basis without removing your fingers from the keyboard or typing out full file paths.
giga-add lists any untracked files or changes to tracked files in an organized multi-select list. Navigate with arrow keys and press space to toggle a change's staged status. Press enter to save the current state.
It's recommended that you bind a git alias to make invoking giga-add faster. For example, you can add this to your ~/.gitconfig:
[alias]
ga = !sh -c 'giga-add'
