highlight of latex equation

[prasook-jain]

Hi everyone, Thanks for building render-markdown. I have a feature request or might be that I lack the knowledge on how to do it.
Recently I started writing latex in my notes. I find that some indication is missing. There is preview of the equation but it doesn't feel that way.

It would be helpful to have some background similar to code block for equation preview.

The highlight group used for latex outputs is RenderMarkdownMath: https://github.com/MeanderingProgrammer/render-markdown.nvim?tab=readme-ov-file#colors

You can set this highlight group to whatever value you like, for example one with a background, and that's how the formulas will get shown. Add something like this somewhere in your config:

vim.api.nvim_set_hl(0, 'RenderMarkdownMath', {
    fg = '#000000', -- black foreground
    bg = '#FF0000', -- red background
})

I did push a small change to make the backgrounds line up nicer: a212596

Thanks, I am kinda new to colors configurations. I am using Lazyvim, and not sure at the moment where to put this in config folder. I put it in option.lua but it's not working, I'll update you once I figure out where to place it.

Out of curiosity what converter are you using to generate the formulas? Is it pylatexenc or something else? My outputs do not look as nice.

I am using utftex.

Initially I setup pylatexenc seeing the readme. While going through issue/pr for latex background color in this repo, found out about another converter in this pr, and switched to that.

I installed it using brew install utflex.
