Change color of Headings

[liston]

Not really an issue, but it is not obvious to me looking at the documentation on how to change the colors of h1, h2, h3 etc.

Ah, I'll work on a better layout to explain what to edit to have what effect.

In this particular case you would provide highlights -> heading -> backgrounds / foregrounds.

The highlight for backgrounds is used for the line and foregrounds is used for the text.

The plugin indexes into the lists based on the level, so h4's get the 4th element. If you provide fewer elements we simply use the last one. So if you provide 3 elements we use the 3rd for an h4.

Hope that makes sense!

• Wonderful plugin @MeanderingProgrammer, really appreciate all the work. I'm just not sure how to change the colors of the headings when I hover over them, I guess it's related to treesitter?
  • Not sure to be honest here's a link to my plugin config
• Here's a video to demonstrate what I'm talking about link to my video
• I see in your readme, and when I run :highight that this is related to @markup.heading.1.markdown
• Everything is exactly the way I want it, I just would like to modify the colors when I hover over the headings
• But don't know how to change them, any help would be appreciated

Thank you :)

2 things:

1. I'm a little lost on how you're getting the results in your video. Mostly in that some of your headings are full width, like the green and blue stretch across the entire window, and some of them end at the edge of the text. They should definitely be consistently one or the other, either all full width or all text width. It might be another plugin clashing, if you're using obsidian.nvim for example its own UI logic might be interfering here: https://github.com/MeanderingProgrammer/markdown.nvim?tab=readme-ov-file#obsidiannvim. I added some known clashing plugins to the healthcheck if you update and run checkhealth render-markdown it might help with that and likely other weird issues that will happen as a result.
2. When you hover over a line all the virtual text and highlights added by my plugin go away, leaving you with the default view for that line. For headings tree-sitter will set the following highlight groups: https://github.com/nvim-treesitter/nvim-treesitter/blob/master/CONTRIBUTING.md#markup. From there if you use a colorscheme it will most likely provide a value for these highlight group. But if you don't like it you can either try a different colorscheme or manually override the value for the various @markup.heading.n.markdown highlights in the same way you set them in the config: vim.cmd(string.format([[highlight @markup.heading.1.markdown cterm=bold gui=bold guifg=%s]], color_fg)), for example. You can run this command at any point in your config, so long is it is after your colorscheme loads.

• Hey, regarding item 1, I don't use obsidian and I also have the headlines plugin disabled, I used that before, but I replaced it for this plugin
  • I use folds a lot, so when a section is folded, that's how headings look, shortened, not sure why, the ones that show the full length are the ones that are not folded
  • here's my checkhealth render-markdown output (not sure what those errors mean though):

    
    render-markdown: require("render-markdown.health").check()

• Regarding item 2, thanks for letting me know that when I hover over a line, your plugin goes away, I tried to override the highlights with an autocommand, wasn't able to, si just loaded those highlights after loading everything and now I was able to set them properly. I really appreciate the help.
