Open Source Lua TeX/LaTeX Software

PGF is a TeX macro package for generating graphics. It is platform- and format-independent and works together with the most important TeX backend drivers, including pdftex and dvips. It comes with a user-friendly syntax layer called TikZ.

The beamer class is focused on producing (on-screen) presentations, along with support material such as handouts and speaker notes. Content is created in a frame environment, each of which can be divided up into a number of slides (actual output pages). A simple 'action' notation is used to specify which material appears on each slide within a frame. The class supports a range of environments to enable complex slide relationships to be constructed. The appearance of slides is controlled by a template system. Many of the elements of slides can be adjusted by setting simple key-based values in the preamble. More complex changes can be implemented by altering specific, targeted definitions without needing to rewrite entire blocks of code. This allows a variety of visual appearances to be selected for the same content source.

VimTeX is a modern Vim and Neovim filetype and syntax plugin for LaTeX files. VimTeX requires Vim version 8.2.3995 or Neovim version 0.9.5. The requirements were updated in April 2024 after the release of VimTeX 2.15. If you are stuck on older versions of Vim or Neovim, then you should not use the most recent version of VimTeX, but instead remain at the v2.15 tag.

CTeX-kit is a collection of TeX/LaTeX/ConTeXt macro packages, related scripts, and resource files made specifically for Chinese TeX users, especially Mandarin users. This project aims to bring together many existing efforts including ctex, xeCJK, zhspacing, LuaTeX-related Chinese support, etc.

PGFPlots, a TeX package to draw normal and/or logarithmic plots directly in TeX in two and three dimensions with a user-friendly interface, and PGFPlotstable, a TeX package to round and format numerical tables. Examples in manuals and/or on the website. PGFPlots draws high-quality function plots in normal or logarithmic scaling with a user-friendly interface directly in TeX. The user supplies axis labels, legend entries and the plot coordinates for one or more plots and PGFPlots applies axis scaling, computes any logarithms and axis ticks and draws the plots. It supports line plots, scatter plots, piecewise constant plots, bar plots, area plots, mesh and surface plots, patch plots, contour plots, quiver plots, histogram plots, polar axes, ternary diagrams, smith charts and more.
