LaTeX

To work with LaTeX, you need a compiler. In Linux we typically use texlive, for more information you can read the TexLive Arch Wiki Page and the texlive package group.

A basic setup is obtained by installing the whole group.

sudo pacman -S texlive

From this, your selected LaTeX editor should pick up the latex command in PATH.

latex --version

Neovim LaTeX support

To have LaTeX support in neovim, install the vimtex plugin using your preferred plugin manager.

Install zathura and zathura-pdf-mupdf to render your PDF and have additional features.

Additionally, you might want to setup an equivalent for the following:

• An autocompletion engine (e.g. nvim-cmp) that connects with vimtex.
• A snippet engine (e.g. LuaSnip).
• A snippet library (e.g. friendly-snippets).

Spellcheck LSP (Neovim)

The spellcheck consumes a lot of RAM. You have been warned.

To have an LSP intended for LaTeX that checks spelling and grammar, in neovim you can install the ltex-ls LSP through your package manager. If you have lspconfig and mason installed, you can run

:MasonInstall ltex-ls

Additionally, you will need a Java runtime

sudo pacman -S jdk21-openjdk

Note that ltex-ls is not compatible with Java 24, hence I suggested jdk21-openjdk previously. If you already had a java runtime installed with Java 24, install Java 21 alongside it and run

sudo archlinux-java set java-21-openjdk

Use your LSP configuration and picker of choice to interact with the diagnostics and fixes.
