1. Description

Provide a helping hand when working with LaTeX documents.

  • Sane defaults
  • Fontification of many popular commands
  • Pretty indentation of wrapped lines using the adaptive-wrap package
  • Spell checking with flycheck
  • Change PDF viewer to Okular or latex-preview-pane
  • Bibtex editor
  • Autocompletion using company-mode
  • Compile your .tex code only once using LatexMk

1.1. Maintainers

1.2. Module flags

+cdlatex
Enable cdlatex for fast math insertion.
+fold
Use TeX-fold (from auctex) to fold LaTeX macros to unicode, and make folding hook-based and less manual.
+latexmk
Use LatexMk instead of LaTeX to compile documents.
+lsp
Enable LSP support in LaTeX buffers. Requires :tools lsp module. Supports digestif and TexLab LSP servers.

1.4. Hacks

No hacks documented for this module.

2. Prerequisites

You will need ghostscript and a latex compiler. All this is provided by the texlive bundle, available through many OS package managers.

Ghostscript <= 9.27 is reported buggy and doesn’t work with auctex’s math previews. (You can check you ghostscript version with gs --version.) Most package managers already have newer versions, but if not you might have to build gs from source.

2.1. Ubuntu

# ⎘
$ apt-get install texlive

2.2. Arch Linux

# ⎘
$ pacman -S texlive-core

2.3. TODO macOS

# ⎘
$ brew install --cask basictex
# If the above doesn't work, then
$ brew install --cask mactex  # WARNING: large 4gb download!

This has not been verified.

2.4. NixOS

# ⎘
environment.systemPackages = [ pkgs.texlive.combined.scheme-medium ];

3. TODO Usage

This module has no usage documentation yet. Write some?

4. Configuration

4.1. Specifying the location of a bibtex file & corresponding PDFs

Reftex has a variable that allow you to specify where it should find your bibliography file(s):

# ⎘
(setq reftex-default-bibliography "/your/bib/file.bib")

4.2. Changing the PDFs viewer

This module provides integration for four supported pdf viewers. They are:

They are searched for in this order. See +latex-viewers to change the order, or remove tools from the search altogether. If you want to exclusively use one tool, for instance:

# ⎘
(setq +latex-viewers '(zathura))

If none of these tools are found, latex-preview-pane (uses DocView in Emacs) is used as a fallback. You can use this exclusively by setting +latex-viewers to nil.

4.3. Using cdlatex’s snippets despite having yasnippet

cdlatex has a snippet insertion capability which is disabled in favor of yasnippet when using :editor snippets. If you still wanna use it, simply rebind the TAB key for cdlatex, which takes care of snippet-related stuff:

# ⎘
(map! :map cdlatex-mode-map :i "TAB" #'cdlatex-tab)

This would favor yasnippet’s expansion and cursor movement over cdlatex’s expansion and movement, but that shouldn’t matter if you’re not using yasnippet in latex buffers.
