Improper syntax highlight for dollar sign $

[milanglacier]

Describe the bug

The highlight for the dollar sign $ is improper

Steps to reproduce

1. open the following example org file test.org

#+title: Test

example 1: the verbatim should be respected
=$= the text should not be highlighted =$=

example 2: text surrounded by dolloar signs that are distanced by over 2 lines should not be highlighted
$2 billion
hello
oh not good
$3 billion

Expected behavior

1. when $ is closed by two =, i.e =$= then verbatim should be respected. i.e there should be no syntax highlight
2. when two $ are distanced by more two lines, text between them should not be highlighted.

Emacs functionality

see description here https://orgmode.org/manual/LaTeX-fragments.html

Text within the usual LaTeX math delimiters. To avoid conflicts with currency specifications, single ‘$’ characters are only recognized as math delimiters if the enclosed text contains at most two line breaks, is directly attached to the ‘$’ characters with no whitespace in between, and if the closing ‘$’ is followed by whitespace, punctuation or a dash. For the other delimiters, there is no such restriction, so when in doubt, use ‘(...)’ as inline math delimiters.

            enable = true,
            additional_vim_regex_highlighting = { 'org' },
        },
    }

    vim.cmd [[packadd nvim-treesitter]]
    vim.cmd [[runtime plugin/nvim-treesitter.lua]]
    vim.cmd [[TSUpdateSync org]]

    -- Close packer after install
    if vim.bo.filetype == 'packer' then
        vim.api.nvim_win_close(0, true)
    end

    require('orgmode').setup {
        org_highlight_latex_and_related = 'native',
    }

    -- Reload current file if it's org file to reload tree-sitter
    if vim.bo.filetype == 'org' then
        vim.cmd [[edit!]]
    end
end

if vim.fn.isdirectory(install_path) == 0 then
    vim.fn.system { 'git', 'clone', 'https://github.com/wbthomason/packer.nvim', install_path }
    load_plugins()
    require('packer').sync()
    vim.cmd [[autocmd User PackerCompileDone ++once lua load_config()]]

I cannot reproduce this. The highlighting for me looks as you in the Emacs screenshot you posted. @kristijanhusak is a latex parser needed here?

Sorry, I missed the option org_highlight_latex_and_related = 'native', and ensure_installed = 'latex'

I have updated the minimal config to make it reproducible.

Thanks for reminding me!

When you set org_highlight_latex_and_related = 'native' it actually loads the whole syntax file from vim's tex filetype. Support for latex is generally lacking and not stable. Maybe you could disable the native and just rely on what's there with treesitter/markup highlighter. Recently some highlights were added (https://github.com/nvim-orgmode/orgmode/pull/428), but not all of them.

Thanks for your advice. I decide to go with org_highlight_latex_and_related = 'entity' right by now
