I have been working on my terminal editor, but I parked that for now -- https://github.com/bloomca/love. It is possible to load a file and edit it, copy/paste works, you can select text, etc. The next step is to integrate with the tree-sitter for syntax highlighting and then with LSP, but it took a bit more time than I wanted.

Another project of mine is to play music from my audio CDs by myself. I built a simple Rust library to read TOC and raw PCM data from a CD drive -- https://github.com/Bloomca/rust-cd-da-reader (works on Windows, macOS and Linux), and a ripper -- https://github.com/Bloomca/audio-cd-ripper, which rips all tracks and encodes it as FLAC and fetches metadata from MusicBrainz.

The next step is to play it. I looked into using cpal (https://github.com/RustAudio/cpal), but I feel like using low-level audio API for each platform is a better approach for learning.
