gwt() — Bash Function to select a worktree via fzf using the worktree folder and a branch

gwt.bash

# vim: ft=bash
gwt() {
  local sel dir esc=$'\033'
  sel=$(git worktree list --porcelain | awk -v home="$HOME" -v esc="$esc" '
    /^worktree / { wt = $2; sub("^" home, "~", wt) }
    /^branch /   { sub(/^refs\/heads\//, "", $2)
                   printf "%s[1;33m%s%s[0m (%s[1;32m%s%s[0m)\n", esc, wt, esc, esc, $2, esc }
    /^detached$/ { printf "%s[1;33m%s%s[0m (detached)\n", esc, wt, esc }
  ' | fzf --ansi \
        --prompt='worktree > ' --height=40% --reverse --no-multi \
        --color='fg+:bright-white:bold,bg+:238,hl:yellow,hl+:bright-yellow:bold,gutter:-1,pointer:red:bold') || return

  dir=${sel%%" ("*}
  dir=${dir/#\~/$HOME}

  git config --global --add safe.directory "$dir"
  cd "$dir" || return
}
