Thank you for this! I have exactly the same problem and was waiting for the solution to present itself, which it now has.

Aside: I use NixOS with home-manager (on linux and mac), which makes this trivial [1]. Added the following lines to my home-manager config:

  programs.git = {
    enable = true;
    ...
    includes = [
      {
        condition = "hasconfig:remote.*.url:git@github.com:<work>/**";
        contents = {
          user.email = "<work email>";
        };
      }
    ];
  }

That certainly looks less trivial than writing it directly in your .gitconfig file. It's the same condition and setting as what's in the article, but now with a build/templating stage and a new programming language to learn with unusual syntax.

While I don't use NixOS or home-manager, I would imagine this provides some extra value: i.e. config is versioned or easy to move between machines.

Curiosity got the better of me so I looked it up at https://nix-community.github.io/home-manager/ and it indeed does purport to provide benefits I guessed at and then some.

Whether that's better than just manually managing things yourself is altogether a different matter.

Agree on your comment re build/templating and new language. Nix is weird and NixOS is complicated. Nonetheless I have convinced myself that I like it.

In TFA the author must set up two configurations: the .gitconfig, and the file which is included in the .gitconfig. Home-manager does this automatically through one config parameter. That is what I was pleased with and wanted to share.
