Is it possible to configure user.name and user.email per wildcard domains in .gitconfig?

Question

I have a work computer, and it's configured globally to use my work email and name when committing. This is good. However, I'd like to make some sort of rule that says, "if the repo origin is github, use user X and email Y"

I realize you can make a config entry per repository, but I'd like it to be more automatic: if the clone is github, it should use github user details. If I clone from work, it should use work details.

Is there any way to configure this globally based on the remote domain? Or another way?

EDIT/UPDATE

I have accepted the answer below, but modified the script just a bit:

#!/usr/bin/env bash  # "Real" git is the second one returned by 'which' REAL_GIT=$(which -a git | sed -n 2p)  # Does the remote "origin" point to GitHub? if ("$REAL_GIT" remote -v 2>/dev/null | grep '^origin\b.*github.com.*(push)$' >/dev/null 2>&1); then      # Yes.  Set username and email that you use on GitHub.     export GIT_AUTHOR_NAME=$("$REAL_GIT" config --global user.ghname)     export GIT_AUTHOR_EMAIL=$("$REAL_GIT" config --global user.ghemail)  fi  "$REAL_GIT" "$@" 

The primary addition is the requirement for two git config values.

git config --global user.ghname "Your Name" git config --global user.ghemail "[email protected]" 

This avoids hard coding the values in the script, allowing it to be more portable. Maybe?

Git 2.13 adds support for conditional config includes. If you organize your checkouts into directories for each domain of work, then you can add custom settings based on where the checkouts are. In your global git config:

[includeIf "gitdir:code/work/"]     path = /Users/self/code/work/.gitconfig 

And then in ~/code/work/.gitconfig:

[user]     email = [email protected] 

And of course you can do that for as many domains of work as you like.
