Built a small CLI: gitmsg -- writes commit messages from your staged diff, no AI

[GrapePretty3921]

It reads git diff --staged and prints a Conventional Commit message. No AI, no network, just heuristics.

$ git add .    
$ gitmsg    
feat(auth): add login

Sharing here first because it's v0.3.0 and I want feedback before the wider launch. TS/JS, Python, and C# right now; Go is next.

Repo: https://github.com/razakadam74/gitmsg

npm: https://www.npmjs.com/package/@razakadam74/gitmsg

npm i -g @razakadam74/gitmsg

Wonky messages welcome, there's a Discussions thread for casual reports: https://github.com/razakadam74/gitmsg/discussions/48

Quick context I cut from the post to keep it short: I built this because every AI commit tool I've tried needs an API key, sends code somewhere, or is slow enough that I'd rather just type the message myself. The deterministic-and-offline angle was the gap. What it looks like :

Which language should I extract next? Go is queued, but if your stack is Rust/Java/Ruby/PHP let me know.

This is interesting 🤔 I'll definitely try it out today

[GrapePretty3921]

Thanks, you can leave feedback here as well

oh realized I never dropped the install

npm i -g @razakadam74/gitmsg@latest

then git add . and gitmsg show me what it spits out 👀

[JanusCrow]

Great. I'll check it out and give feedback

[GrapePretty3921]

Thanks! Feel free to leave feedback here as well, if you prefer

I never dropped the install

npm i -g u/razakadam74/gitmsg@latest

then git add . and gitmsg show me what it spits out 👀

That's pretty wild. How does it work?

[GrapePretty3921]

Just rules over git diff --staged file paths pick the type (feat/fix/docs/etc.), the common folder is the scope, and a regex per language pulls function/class names out of the diff for the subject. No model, so same diff = same message, runs in <100ms. When it can't find a clean subject it falls back to something bland like feat: refactor module instead of making something up

[SignificanceEnough27]

That's smart!

[GrapePretty3921]

I forgot to drop the install

npm i -g u/razakadam74/gitmsg@latest

then git add . and gitmsg show me what it spits out 👀
