Adjust treesitter text highlights

[andersevenrud]

Stylize certain treesitter highlights to improve visibility in formatted text documents, like Markdown.

Just saw that the Markdown treesitter parser was merged into nvim-treesitter, and tried it out. All of the sudden my files looked really flat :sweat_smile:

I'll have to look at some other filetypes that uses these same treesitter highlights to make sure nothing was really messed up... but I'm fairly confident.

Do you have any thoughts on this (or maybe have experience with some other filetypes I need to look out for) @gegoune ? :blush:

I was to make a comment on new tree sitter's parser for MD. You are fast! :) There also is new make tree sitter parser which has no highlighting with nordic at all. I will check out this PR in few moments and report back.

@gegoune Just a note on the new make parser, it seems to work fine for me :thinking: But if you have some issues with it just open an issue and I'll have a look!

Ah, make does work indeed, I was just checking on very simple Makefile which just happened to have no highlights applied except for one on : which I did not notice.

Please hide this comment after you read it. :)

Markdown looks nice, good job! Couple of missing highlights and one typo I mentioned above.

From what I can tell, these changes should look fine anywhere else too. So I'm going ahead with a merge here.

Thanks a lot for your time @gegoune . Really appreciate the hands-on :smile:

Thank you for all your work on this amazing theme. I wish I could help, but I bet I cannot come up with anything visually pleasing. :)

[andersevenrud]

I bet you could. You seem to have a good eye for these kinds of things :)
