We launched learnlatex to provide high-quality teaching of core LaTeX concepts with interactive examples. From the start, we wanted to offer the ‘course’ in multiple languages: this was part of the structure from the start. Over time, several people have… Continue Reading →

When the LaTeX Project team took over maintenance of LaTeX from Leslie Lamport, LaTeX2e was planned as an intermediate release to resolve immediate issues with the then-current LaTeX2.09. The ‘e’ (or properly ε) was meant to indicate a small change… Continue Reading →

The latest release of LaTeX went to CTAN on Friday, and moves us forward in truly automatic tagging for PDFs, particularly for mathematics. As part of the work, we have been looking at the capabilities of different engines. Here, I… Continue Reading →

The LaTeX Project have been working for about 4 years now on creation of automatically tagged PDFs from (more-or-less) unmodified LaTeX documents. We’ve been reporting regularly in LaTeX News, and things are moving forward nicely. We (Frank, Ulrike and I)… Continue Reading →

Controlling expansion has been a key part of expl3 from day one. A basic expl3 function name such as \foo:nn shows how many unmodified braced arguments it takes: so called n-type arguments. We can then create variants, which can lead… Continue Reading →

Right from the first version, siunitx has supported uncertainty values in numbers. Uncertainties are a key piece of information about a lot of scientific values, and so it’s important to have a convenient way to present them. The most common… Continue Reading →

It is quite natural to think that separating a word up into individual characters is quite easy. It turns out that for the computer this isn’t really the case. If we look at a system that understands Unicode (like XeTeX… Continue Reading →

A topic that comes up for many LaTeX users is how best to mark up math mode in sentences: inline math mode. LaTeX offers three (!) official ways to do that $…$ \(…\) \begin{math} … \end{math} The last version is… Continue Reading →

I mentioned recently that I’m working on features for siunitx v3.1. One area that I’ve now been able to commit is improvements to handling complex values. In v2, you could give complex values in the normal argument to \num or… Continue Reading →

I’ve now done 49 (!) minor releases of siunitx on the v3.0.x branch. These have addressed quite a few minor bugs: I expected to have to do a bit of work since the shift from v2 was quite major. Things… Continue Reading →
