I set up Supermaven AI-based code completion (Co-pilot competitor) using their #Neovim plugin. They have a free tier, which seems to work great, and the Neovim plugin could not be simpler to install and use. Only used it for less than a day so far, but I like it. It's fast. https://supermaven.com/ 

I am working with protobuf files and wanted to write some new tooling for code generation that doesn't use Go's horrible protoreflect.

I started parsing the files with Treesitter (in Go), which works great. Writing query S expressions was kinda annoying but then I found that #Neovim has a built-in #Treesitter query editor and live tree/document playground.

Holy crap! This is sooooo nice. 🤯
