If you use mynewsdesk-git-pair to manage pairing authors in git, add the following snippet to your .bashrc
to enable tab completion of pairing author names.
_git_pair () {
__gitcomp_nl "$(git config --get-all git-pair.authors | sed 's/\([^ ]*\).*/\1/')"
}
You will need programmable bash completion set up, and the git completions that use it. On OSX with homebrew that's as simple as
brew install bash-completion
brew install git
