Hi,

There is a new lmtx upload.

-- The svg inclusion via metapost has been upgraded and cleanup a bit, using some more recent metapost features. There are some new (not yet all documented metapost) features.

-- In the process, support for LCH colors has been added, which is documented in the (eg luametafun manual).

-- The math manual is not yet there because we were distracted by improving support for envelopes (penbased outlines) in metafun. This is still work in progress, some is present and discussed in the manual, and we'll come back to that sometime next month. Given the next item, we also might need to change some in the manual (different focus).

-- Because we have users who have to conform to the European Accessibility Act we have been wondering how to deal with that and at Mikaels place there are two demands: distinctive colors and tagging and especially math (somehow validators love to check that). Colors never were an issue as they can be controlled, and tagging math neither, especially because nothing was/is done with it anyway, but ... we are happy that we found a reasonable (more modern and future proof) way out.

As explained / shown in the attached document we're basically forced to choose a different approach with math (a pity as we worked hard to get the rendering right but the attached file works fine in the viewers that we tested).

-- We like to hear from users what other demands wrt accessibility there are. We're not interested in the (commercial) big money aspects (of pdf and tagging) nor in the politics behind it (changes over time). What are the demands, so that we can see how to make it work or just work around it (as it's kind of boring to cook uyp complex features , esp compared to playing with metapost).

-- Furthermore .. the usual bits and pieces as discussed on the list and otherwise.

-- If you have troubles (crash) you need to wipe the cache due to a change in lua bytecode storage (no easy way to catch it).

Hans & Mikael

In addition to what Hans wrote, I need to write and apologize. About two years ago I was working on a big math project and needed SyncTeX (code <-> okular) to work with it to get a smooth workflow. After fighting it for several weeks, mailing Hans back and forth, without any real support from Hans since "he was not using SyncTeX", I sent a false patch to him that I claimed worked. It must have gotten in without even being tested(!). Since then SyncTeX support for ConTeXt has been broken. Strengthened about how easy it was to add code to this project, and still frustrated about the project (that is still not finished), I started "collaborating" with Hans, mainly on math. During these years, I have been baffled about how easy it has been to add malicious code, he just swallows everything. I only needed to find out what Hans really uses himself (a few tables, he likes colors, and he has a weak point when it comes to "nice" metapost images), and then to add patches for other stuff. For math, in particular, he seems to have no understanding (sorry Hans). I am worried about the Dutch school system. Nevertheless, I have, during this time, more and more enjoyed our discussions, and so I started to feel bad about my "patches", and sorry for Hans. Thus, I have lately reverted, part by part, the bad code. Only a few of them are left (but don't tell Hans!). I also got a feeling that Wolfgang, checking all the code, since long did see this through. Thus, in the latest upload, for example, you might get SyncTeX working again, but you might need to add \setupsynctex[state=repeat]. No guarantees. Again, my sincere apologies to all ConTeXters out there who have not gotten the result they expect and deserve. I assume that Hans will kick me out when the last patch is sent, so I will delay it as much as possible... /Mikael
