Git bash-completion with filename support?

Question

is there a bash-completion script that supports filename completion? I use mostly mercurial and there I can type:

hg diff test/test_

Answer 1

This solves the git diff problem for me, put the following in .bashrc:

alias gid='git diff'
__gdiff () {
    local cur prev opts
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"
    opts=$(git status --porcelain | grep '^.[^ ?]' | cut -b 4-)

    case "${prev}" in
        gid)
            COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
            ;;
    esac
}
complete -F __gdiff gid

And then do gid instead of git diff . It may be simplified, but seems to work well as a quick fix.
