Interactive git clean using a selector tool like peco or fzf

git-clean-with-selector

#!/bin/sh

set -e

while getopts 'x' opt; do
    case "$opt" in
        x)
            flags=--ignored
            ;;
        *)
            exit 64
            ;;
    esac
done

shift $((OPTIND - 1))

lines="$(git status --porcelain $flags | sed -n '/^[?!][?!]/p')"

if [ -z "$lines" ]; then
    echo "no files to clean"
    exit 0
fi

selector=$(git config selector.multiple)
: ${selector:=peco}

lines="$(printf %s "$lines" | $selector)"

[ -z "$lines" ] && exit 0

perl -e 'print "$1\0" while $ARGV[0] =~ /^.. (.*)$/mg' -- "$lines" | (
    cd "$(git rev-parse --show-toplevel)"
    xargs -0 rm -v
)

To use fzf instead of peco, run this:

git config --global selector.single fzf
git config --global selector.multiple "fzf -m"
