TeXLive Accessibility Conformance Report (International Edition) (Based upon VPAT® version 2.4)

TeXLive is the reference distribution of TeX and related software supported by TeX Users Group, a membership-based not-for-profit organization dedicated to support, promotion and advocacy of TeX typesetting system created by Donald Knuth and maintained by the international community of developers. As of 2024 TeXLive contains more than 490 programs and more than 8000 software packages.

Notes

TeXLive is a complex software suite, intended to the produce typeset products in various formats (PDF, HTML, DVI, XML to name a few). In all case it takes an input code written in a machine-readable form and translates it to an output format, suitable to publication in the traditional (hard copy) or electronic form.

This document covers only the software used to convert the input code to the output format. The creation of the input code is outside the scope of this document, since it is done by third party software. TeXLive software can accept as input text files created in any authoring tool. TeX Users group is aware about fully accessible authoring tools, and promotes them on its web pages and publications.

A separate issue is the accessibility of the output documents created with TeXLive software. The accessibility features of these documents depend on the settings in the input code and the packages used, and thus is not covered by this document. TeX Users Group strives to make the creation of full accessible documents using its tool as simple as possible, and to make the accessibility features the default settings of our software. This is an ongoing effort, involving many developers. TeX Users Group welcomes any help in this work. The current state of the effort can be found at https://tug.org/twg/accessibility/overview.html.

The tools provided by TeXLive are accompanied by technical documentation, both included in TeXLive itself, and separate: there are many books, courses and other materials about TeX. Many of the latter a fully accessible. The main documentation of TeXLive, supported by TeXLive team, is accessible as well. Most of the documentation for several thousand software packages in TeXLive is provided in PDF or text format. By requiring machine readable textual sources of all documentation provided by TeXLive packages, we ensure a certain level of accessibility for all documentation. However, the full audit of the documentation for all 8000+ packages created by many thousands of volunteers is not feasible at this time. TeX Users group supports the efforts of making all TeX documentation fully accessible.

Introduction

There are several ways to define “the full documentation for TeX and friends software”. In one meaning of these words it comprises all books on TeX, LaTeX, ConTeXt and other systems included in TeXLive, all issues of the journals published by TeX Users Group and other users produced documentation. Of course it would be impossible to estimate the accessibility of all this documentation, comprising hundreds thousands of pages written over three decades.

Another way is to count only the documentation for the packages included in TeXLive. This includes documentation for 8000+ packages, which makes the full audit rather impractical.

In this document we discuss only the main manual for the system, available with the installation and at https://tug.org/texlive/doc/texlive-en/texlive-en.html. We note, however, that documentation for all TeXLive packages is available as source text files, and thus is highly accessible.

In the tables below the success criteria apply to Web and Electronic Docs paragraphs of VPAT.
