Been using Debian and vim for almost 25 years now. Tried many IDE's but they're distracting, bloated and slow.
My main language is python and for that I use jedi-vim (which allows me to jump to a definition), fzf with ripgrep to easily open files and search for specific things, and ALE that runs ruff formatting and linting. Tmux to keep my terminals organized and openbox to make it stylish and stay out of the way.
No LSP, no autocomplete, and sure as hell no AI nonsense.
