An option to change directory to the grabbed repo right after cloning

[pilosus]

Given that git-grab makes paths to a cloned repo more nested and can be invoked from everywhere on the file system, it's a bit tedious to copy-paste the path to the repo directory from the output if I want to change directory right after the cloning.

What would be helpful is an option like -f/--follow or --change-dir or whatever that will be an equivalent of the following:

git grab <REPO-URL> && cd <REPO-PATH>

I admit this would be convenient. I don't think this is possible as the current directory is state within the shell. git-grab could call chdir but as soon as it exited the pwd would be returned to where ever the shell was. If there is a way to do it, I'd be happy to be proved wrong.

@wezm you are most likely right, but I opened the issue anyway hoping someone could suggest a solution.
So far I was able to do only a super dirty hack with an eval in the command invocation that doesn't look nice at all :-D

$ eval "$(git grab <REPO-URL> | gg-cd)"

where gg-cd is a tiny wrapper:

#!/usr/bin/env bash
set -euo pipefail

grab_output=$(cat)
target_dir=$(echo "$grab_output" | grep -oE 'Grabbed .* to .*' | sed -E 's|.* to (.*)$|\1|')

if [[ -n "$target_dir" && -d "$target_dir" ]]; then
  echo "cd \"$target_dir\""
else
  echo "echo 'Failed to extract target directory or directory does not exist' >&2"
  exit 1
fi

Anyway, feel free to close the issue, if you think it's hopeless

Yeah it's not possible in git-grab directly. We could do something like what zoxide does and have wrapper shell functions that invoke the cd builtin:

$ which z
z () {
	__zoxide_z "$@"
}

$ which __zoxide_z
__zoxide_z () {
	__zoxide_doctor
	if [[ "$#" -eq 0 ]]
	then
		__zoxide_cd ~
	elif [[ "$#" -eq 1 ]] && {
			[[ -d "$1" ]] || [[ "$1" = '-' ]] || [[ "$1" =~ ^[-+][0-9]$ ]]
		}
	then
		__zoxide_cd "$1"
	elif [[ "$#" -eq 2 ]] && [[ "$1" = "--" ]]
	then
		__zoxide_cd "$2"
	else
		\builtin local result
		result="$(\command zoxide query --exclude "$(__zoxide_pwd)" -- "$@")"  && __zoxide_cd "${result}"
	fi
}

$ which __zoxide_cd
__zoxide_cd () {
	\builtin cd -- "$@"
}

git-grab could perhaps have an extra flag to change its output to be more friendly to being read by the shell function.
