gitusers is a small helper to set up and maintain different git credentials specific to different repositories/remotes
set up a local config file in ~/.config/gitusers.json in the following structure:
[
{
"short": "foo",
"name": "Foobar",
"email": "[email protected]",
"privkey": "~/.ssh/foobar"
}
]
calling gitusers will check if the local git config matches a known user-short, in case of a match, it prints the user-short back, in case of either a misconfiguration or an unknown user, it will report an error in zsh-colors (argless usage is for embedding in your prompt [currently only zsh])
calling gitusers <user-short> will configure the current git repository with the given user config
calling gitusers -l will list all known users in your ~/.config/gitusers.json
calling gitusers <user-short> clone <url> will clone an upstream URL with the given user config
the first idea was to use gitusers to change all remote urls according to a schema
for each specific user in ~/.ssh/config, e.g. for github we would make another
section with a differently named host (.e.g github_otheruser), set the section up
to use our specific privkey and then use that host in the desired git remote
however, this sadly doesn't cover submodules in a reasonable way, as submodules won't follow local naming schemes
thus the current way is to set the core.sshCommand via git config and
override the ssh command to include the specific privkey see https://superuser.com/a/912281, e.g.
git config core.sshCommand "ssh -i ~/.ssh/id_rsa_example -F /dev/null"
