In my attempt to venture in the realm of LaTeX3 coding, I was wondering if a list of answers, in LaTeX3, can be made? That is, a list of links to answer in which users here at TeX.SX have used such coding. This will enable me to look at this post and look at samples instead of searching for examples everywhere on the website.

  • Here is one! Couple of answers have used LaTeX3.

    Did you see tex.stackexchange.com/questions/84605?

    @cryptic0 The question is really about expl3, the programming layer, which is available and usable

    The LaTeX3 project was announced at conference in Prague in 1992. I was there. This is more than two decades. But users are using a provisional release (called LaTeX2e) still. And here are many of history problems (like cm-fix.sty, for example) -- they are as prisoner ball in LaTeX2e. Despite this users don't need any changes.

Almost all LaTeX3 answers will use expl3 or xparse packages, or as egreg says use \ExplSyntaxOn (which is the LaTeX3 analogue of \makeatletter to allow package code in the preamble) thus a link such as


will show most of the things that you wish to find.

or of course those explicitly tagged:


  • Sorry to dredge this up, but does this mean that \ExplSyntaxOn is similarly implicit in package/class files? Jul 9, 2013 at 23:39

    @SeanAllred It means it probably would be implicit if there were a latex3 package loading mechanism, but there isn't so far:-) Jul 9, 2013 at 23:47

Though the question was asked long back, for anyone who views this and would like to learn LaTeX3 Programming, Programming LaTeX3: Creating functions provides a really good introduction with number of examples and the documentation can be used for further understanding and exploration.
