nvim-treesitter VS tokyonight.nvim

Then open the file in your favorite code editor, that is for me neovim btw, you might want to install a treesitter to provide some syntax highlighting although nice but not necessary, in vscode you can install a plugin for the syntax highlighting.

Neovim could use the default regex based grammar that Vim uses for syntax highlighting. But I recommended installing treesitter. This uses a concrete syntax tree to provide more semantic meaning to tokens, allowing enriched (and faster) highlighting.

For example, let's set a color scheme, I like TokyoNight, you can set any you like:

I have several production servers I work on that we use standard vim9 on to edit config files, etc. I love tokyonight.nvim and would love to be able to use it or something as close to it at possible with vim9, but have yet to be able to find anything. Any suggestions?

Tokyonight highlight file almost 1000 Lines

Looks like tokyinight.nvim.

This should come from DiagnosticVirtualTextError and usually the colorscheme you're using sets it. Check the documentation of your colorscheme to see if you can change highlight groups in your colorscheme or try to link the DiagnosticVirtualTextError to a different HighlightGroup or color. The colorscheme you're using seems to be linking DiagnosticVirtualTextError and keywords to the same HighlightGroup. Or you might try a different colorscheme which (hopefully) doesn't have problems like that. One I would suggest is Tokyonight, if you would like to check it out.

I think it 's tokyonight https://github.com/folke/tokyonight.nvim

So for tokyonight.nvim, when that folder is added to the rtp:
