macOS compose sequences via text snippets

I’ve recently read this [1] post about the compose key on linux which I thought it was pretty cool and I was looking for something similar on macOs.

One issue with apps emulating the linux default input way [compose-key] + [sequence keys] was that im a clumsy typer and so i’d rather see what im typing before its replaced with the result of the compose sequence. Since I’m a dev but i haven’t had much experience coding in swift i thought i would see if i can use claude code to create an app for myself to use compose sequences via text snippets.

The result is SnippetCompose: https://github.com/horstf/SnippetCompose

This way I can input compose sequences but see the input and correct myself, for example typing ::C= will be replaced with €.
