I didn't want to have to organize my work and personal repos using a directory structure, so I use matching on the remote instead. Since my job uses a GitHub organization, I'm able to conditionally include a config file that uses my work email in any GitHub repo under that organization.

I wrote it up here, if that sounds useful: https://www.brantonboehm.com/code/conditional-git-config/

Oh nice, this will remove an annoyance in my dotfiles repo by letting me share my gitconfig between 3 different configurations (home linux amd64 box, work macOS arm64, client macOS arm64) Thank you for sharing it!

What do you have in your git config that requires switching over host architecture?

I put those there as a way to show I couldn't just switch on $ARCH or $OSTYPE similar. I should have explained that better, sorry about that.

Surprised no one has mentioned chezmoi[1], which takes parameterization of configs to its awesome, extreme conclusion[2].

I use virtual machines for development.

Interesting, but why not just configure direnv to set appropriate env vars based on your current directory? That works for more than just git.

I prefer the method used in the article. All the settings are neatly kept in a git configuration file, and I don't have to track down where direnv keeps them, or remember that I need a separate tool in order to make it work. Also this allows you to set git config options that don't have a corresponding environment variable.

Something that wasn't addressed: when is the configuration read? Does this happen on every command-line git command execution? (I'm guessing "yes", but...)

Yes. Git doesn't daemonize, so there's no way it can avoid reading its configuration every time you run a command. Ultimately what the command ends up doing likely takes orders of magnitude longer than reading and parsing the config file, so it's not really a big deal.

Why downvotes? It is the most effective way to separate config. If any of those "condition" fails, you may nuke or compromise your repo!

I only do work stuff on the work laptop so the git config is entirely separate from my personal one since its on a totally separate machine

Can different .git-credentials files also be loaded conditionally? When one uses https access with multiple accounts....

I use the technique in article for something similar that solves the same problem. I'll find it on pc in a sec.

Ah, gotcha. I thought you might have some weird, nice needs and was curious about it :)
