Describe the bug

i copied and pasted the sample for a .md latex file, however nothing rendered. when i run :checkhealth render-markdown i see in Treesitter that there is no latex parser.. however i have the texlive package installed...

Expected behavior

# Latex


$\sqrt{3x-1}+(1+x)^2$


$\sum \epsilon \subset \beta$


$$
f(x,y) = x + \sqrt{y} \\
f(x,y) = \sqrt{y} + \frac{x^2}{4y}
$$

> [!caution] Hi!
> This is a Test!

this should render a latex view. it does not.

Additional information

No response

was missing tree-sitter.

cargo install tree-sitter-cli

fixed it.

but the rendering is not right rn...

[Humam-Hamdan]

in pure kitty it renders fine. with tmux nope.

[Humam-Hamdan]

was a config.fish problem.

another question: can i make it so that the render appear below the text?

[MeanderingProgrammer]

was missing tree-sitter.

This will depend on how you install neovim, since you're running 0.11 I assume you're building from source, in which case you'll need to make sure all the system dependencies are installed, like tree-sitter, luajit, etc.

From there you gotta get the latex parser installed, I thought you would need tree-sitter to install any additional ones, but maybe that's not the case?

In either case looks like you got that part figured out.

I have no idea why tmux would cause an issue, testing on kitty, wezterm, and ghostty all 3 work with and without tmux so maybe a system specific thing or some tmux configuration setting.

Here's my config if that helps: https://github.com/MeanderingProgrammer/dotfiles/blob/main/.config/tmux/tmux.conf

Not right now but I can add that as a feature

it was because i was forcing fish to get fastfetch everytime. an interactive-shell condition solved that

i get it from the ppa. but yep needed to install rust and get tree-sitter from cargo -since the one in the ubuntu repos is 0.20.8 which is just old.-

Added this feature here: 43a971e

Can set it via:

require('render-markdown').setup({
    latex = { position = 'below' },
})
