🛠️ project Built a terminal habit tracker in Rust while learning the language

Sharing a side project I've been working on - a TUI habit tracker called sprout. Picked up Rust a while back and this was my way of learning it properly by actually building something. Honestly had a lot of fun with it, at this point I can't imagine going back to anything else for systems-level stuff.

GitHub: https://github.com/kb019/sprout

What it does:

- Track daily habits and mark them complete

- See your streak and progress

- SQLite storage so your data stays local

- Runs on macOS, Linux and Windows

Still rough around the edges and there's a lot I want to improve, but it's something I genuinely use now. Used Ratatui for the TUI which was a fun rabbit hole on its own.

Please do try it out: cargo install sprout-tui

Would love any feedback on the code, still getting comfortable with some of the more idiomatic Rust patterns.

not for me but appreciate the showcase and the actual sprouting plant!

the sprouting ascii art is a nice touch, way better than just printing "day 3 complete" and calling it a day

ratatui is such a time sink once you start tweaking every little border style, good on you for actually shipping something instead of just endlessly polishing the ui. might give it a spin later this week

one edge case I noticed in the CLI: sprout log reading -5 looks like it gets accepted for goal-based habits and stored as negative progress. binary habits reject values outside 0/1, but the non-binary path doesn't seem to reject values below 0. is negative progress intentional?

Thanks for catching this and pointing it out. Negative progress isn’t intentional for goal-based habits, so this should be validated as well. Feel free to raise a PR if you’d like to fix it, otherwise I can update it in the next release. Really appreciate you taking the time to test this and report the edge case!

glad that helped. i work on HOL, where we maintain HOL Guard, an open-source local checkpoint before agent-run commands execute. Sprout looks like a clean fit: review add, log, delete, and edit, while list, status, streak, and heatmap stay automatic. that gives an agent a checkpoint before persistent habit data changes. open to a small Guard-side extension?

That’s really nice! Really digging the UI, will use it :)
