semshi VS tree-sitter-ruby

Try https://github.com/numirias/semshi Semantic Highlighting for Python in Neovim

Yes, I think treesitter highlight is yet limited and still a mess. I am still sitting at semshi, but look forward to switching to treesitter completely in the future.

I use neovim with my transparent kitty terminal. Kitty doesn't make the actual letters transparent so they are still easy to see, just the background of the terminal. Then ontop of that my syntax highlighting is really intense (https://github.com/numirias/semshi) and my background is pretty dark (lots of blacks and dark blues and other dark complementing colors that are easy on the eyes) so text is still easy to see while still looking quite nice IMO.

One of the best and easiest way is using plugin numirias/semshi.

https://github.com/numirias/semshi gives pretty cool semantic highlighting.

Vim's highlighting is more limited. Vim uses regex for syntax highlighting as opposed to using ASTs. You can try looking in the Neovim direction instead. Here's some Neovim-only plugin https://github.com/numirias/semshi for python specifically.

It's describe under the highlights title in README : https://github.com/numirias/semshi#highlights

semshi is quite good.

Just use tree-sitter with neovim. It has a Ruby plugin as well https://github.com/tree-sitter/tree-sitter-ruby

@chrisseaton you are correct, the JSON file is generated. The handwritten parts are:
