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

We're done with math. After years of active development, Mikael and Hans have
decided to quit working on math, and concentrate on \METAPOST\ and handing over
to the next generation instead. We lost our user to the way more popular
alternative (frozen in stone standards). Also, we had it with suboptimal math
fonts, Unicode math not getting improved, MathML constantly being changed,
browsers dealing with math differently every few years, math archives getting
polluted with tons of useless tagged math.
There are other motivations, like the European union imposing strict rules with
respect to accessibility in educational content management systems, and Dutch
schools trying to get rid of math in favor of simple calculus, if at all. This
is
why the next iteration of the engine will no longer have a math engine:
MathLessTeX. Of course, in the beginning \MLTX\ will be compatible with \LMTX,
because we owe that to the users and we need to prototype the new engine anyway.
In order to get an idea of how we will get rid of the disturbing formulas, you
can load the module:
\starttyping
\usemodule[math-goodriddance]
\stoptyping
Until becoming the default setting, the command \typ {\goodriddancemath} will
bring you into \MLTX\ mode while \typ {\badriddancemath} will bring you back to
the obsolete \LMTX\ mode. Like:
\startbuffer
\usemodule[math-goodriddance] \goodriddancemath
Who wants to solve the equation \m {x + 1 = 4} or deal with the function \m {x
\mapsto
\root [3] {x}}, when we have AI around the corner to help us out with simple
and silly
things like the Pythagorean theorem: \m {a^2 + b^2 = c^2}, or even with more
advanced
math like geometric series: \m {\sum_{k = 0}^{+\infty} x^k = 1/(1 - x)}?
We will not support complicated nonsense stuff like:
\startplaceformula
\startformula
F__{1}____{2}(a,b;b;z) = (1 - z)^{-a}
\stopformula
\stopplaceformula
When developing this Hans' Swedish improved a lot. {\language[sv] Den lilla del
av
befolkningen som handlar på IKEA och tittar på fåniga krimserier förstår kanske
detta:
\im {\sqrt {x + 1} = \sin(4 + y)}!}
\stopbuffer
\typebuffer[option=TEX]
Which gives us the beautifully typeset:
\startcolor[darkblue] \getbuffer \stopcolor
We hope that the highly respected Swedish Academy will consider our prose in
their upcoming evaluations. Our first submission to the leading \TEX\ journal
was
however rejected. We are currently on a major revision in order to satisfy the
hopefully less critical \NTG\ Maps Editors. It is therefore our sincere hope
that
you will be able to read more on this topic in the near future. Currently only
English and Swedish are supported. But our next research project, lead by two
young promising linguists, will hopefully result in support for more languages.
They will present preliminary results at the prestigious international BachoTeX
conference in May 2024.
