Tennis is a cli tool that prints stylish tables in your terminal. You point it at csv, json or even a sqlite file and it renders a nice table. Project is still very young, I pushed out 0.4 earlier today.
This is my first Zig project and I am loving it so far. You may recall my post-mortem post here a few days ago… Still enjoying zig, using 0.15.2 at the moment.
I picked zig because I want tiny binaries and I fell in love with the fast compilation. I am having excellent luck pairing with codex. The LLMs add features very quickly, but it takes a senior engineer to keep it idiomatic and maintainable.
