gh cli wrapper with multiple users depending on repo

gh-multiuser-wrapper

#!/bin/bash
# This wrapper will enable multi user support for github cli "gh".
# You need to link your "gh" command against this script and it will 
# call the original command after changing the config credentials to the
# specific user

gh_user=$(git config gh.github.com.user)

# print infomessage
if [ -z "$gh_user" ]; then
  echo "-> gh_user is not set, do so with 'git config gh.github.com.user NAME' for this repo"
  exit
else
  echo "-> using gh_user: ${gh_user}"
fi

# the general gh config file is symlinked to the config file for this specific user
rm ~/.config/gh/hosts.yml
ln -s ~/.config/gh/hosts-${gh_user}.yml ~/.config/gh/hosts.yml

# this is the original gh-command path, yours might differ from this
/usr/bin/gh $@

Nice :) Slightly changed the last line in my case to make this work:
$(which gh) $@

Thanks. I didn't use your implementation directly, but it gave me the idea to wrap gh in a script that pulls GH_TOKEN and GH_ENTERPRISE_TOKEN from a keychain. It's a hack, but seems better than permanently storing unencrypted credentials in hosts.yml.
