Use lervag/vimtex in_mathzone

[LuisA92]

Hello!

I am currently transitioning to Neorg for my daily notes. My work heavily relies on writing math using LaTeX. My setup uses LuaSnip to speed up my math notes (I used this tutorial to setup my snippets). A problem I ran into was using VimTeX's vimtex#syntax#in_mathzone() function to trigger certain snippets only inside of $$ or $$ $$.

I found a workaround here. The workaround involves creating a ~/.config/nvim/after/syntax/norg.vim file and adding the following

autocmd BufRead,BufNewFile *.norg set filetype=norg

syntax include @neorg.markup.in_math_zone $VIMRUNTIME/syntax/tex.vim
syntax region neorgMathZone
      \ start="\$" skip="\\\\\|\\\$" end="\$"
      \ contains=@neorg.markup.in_math_zone keepend

You should also make sure that you add the following to your treesitter config

require('nvim-treesitter.configs').setup({
highlight = {
    additional_vim_regex_highlighting = {'latex','norg'}
},

--The rest of yourtree sitter config

})
