LaTeX3 development code
The broader LaTeX3 code consists of a number of modules targeting different functionality intended as building blocks within LaTeX2e and/or as stand-alone code prototyping ideas for future development. These modules are currently managed using version control in a single GitHub repository named
Notable LaTeX packages part of this repository include
l3packages/xparse. Full information about the packages included in the repository is documented in the top-level README of the repository.
The LaTeX3 code is managed using
l3build configuration files.
l3build is a cross-platform Lua program for automating the building and testing process of (primarily) LaTeX package files, and it is also developed by the LaTeX3 team.
Most of the LaTeX3 code is available and kept up-to-date through a TeX distribution. For example, in TeX Live you can update to the latest version of
l3kernel, which provides the programming layer
tlmgr update l3kernel
If you wish to test using unreleased code in GitHub, you may clone the repository using
git clone email@example.com:latex3/latex3.git
To install packages from the development repository, using
l3build as follows:
cd l3kernel texlua build.lua install
You may also wish to ‘fork’ the repository on GitHub and clone your fork if you wish to make changes to the code and contribute them back via Pull Requests but please read the contributing guidelines first.
You may raise any issues in the Issue Tracker. These issues are usually intended to report issues relating to the code, such as documentation clarifications, missed functionality, or bugs.
The concepts developed by the LaTeX3 development code, as well as their implementation, are under discussion on the mailing list ‘LATEX-L’. You can join this list, which is intended solely for discussing ideas and concepts for future versions of LaTeX, by sending mail to listserv@URZ.UNI-HEIDELBERG.DE containing the line

Listserv web interface
There exists a web interface to the list that can be used to read through the posts sorted by topic and month. By default this is available to the general public in a read-only mode. If you like to be post using this interface, you have to be subscribed to the list and you need to log on (which is an option on the page).
This list is archived and, after subscription, you can retrieve older posts to it by sending mail to the above address, containing a command such as:
GET LATEX-L LOGyymm
where yy=Year and mm=Month, e.g.
GET LATEX-L LOG1703
for all messages sent in March 2017.
