[Hans Hagen via ntg-context]

Hi,

I uploaded the last of series 2.10.07 as prelude for bachotex. That one 
also can do this:

\newfloat \MyFloat
\MyFloat \pfsin \floatexpr 1.25 * \pfpi \relax
\the\MyFloat

\the \pfsin \floatexpr 1.25 * \pfpi \relax

The syntax is like \numexpr and \dimexpr but the \pfsin (and other 
functions) are (as usual with these things) not real primitives but 
(\untraced) luacalls.

Of course it is all still somewhat experimental but likely to stay ...

Hans

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).

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.

Hi,

as we're around texlive code freeze time we're also in upload mode

- i uploaded a new lmtx
- i also added linux and windows 32 bin (as it seems to have users)

- we're now using lua 5.5 which has one restriction (was already 
announced a while ago):

for i=1,10 in t do
     ....
     i = 2 * i
     ....
end

should now be:

for i=1,10 in t do
     ....
     local i = 2 * i
     ....
end

as one cannot change the (local constant) i which actually is not that 
different from what metapost does. The good news is that voilating this 
is reported when a lua file is loaded so one can't get it unexspectedly.

Hans

[Hans Hagen]

Hi,

I uploaded a new lmtx. There are some new features that wil be revealed 
in the future (likely after the meeting) but here is one:

\starttext

     \defineoverlay
       [test]
       [\color
          [blue]
          {TEST
           \inframed
             [foregroundcolor=red]
             {xxx}
           TEST}]

     \framed
       [background=test,
        foregroundstyle=\switchtobodyfont[small]]
       {test}

\stoptext

 From now on many commands accept (properly) nested [] inside commands 
that use [] as fences (like the setup commands) where it makes sense. It 
is up to the user to decide to use {} (as before) or not but it is less 
error prone.

It is now also possible to nest setups as in

\starttext

\startsetups one
     \startsetups [three]
         HERE
     \stopsetups
\stopsetups

\startsetups two
     \startsetups [three]
         THERE
     \stopsetups
\stopsetups

\setups[one] \setups[three]

\setups[two] \setups[three]

\stoptext

As part of the ongoing improvements on math rendering we added some 
classic lm/cm kerns (between upperacse and periods / commas) in the 
goodie files.

Some lowlevel manuals have been extended, explaining experimental 'named 
cross macro nesting parameter referencing' and 'constrained cq. retained 
assignments', but that is only relevant for those interested in 
overcoming some limitations in the traditional engines.

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

I uploaded a new lmtx. Apart from the modules installer (that Hraban has 
to check) and subtle improvements in math (we're now in tweaking 
penalties mode) there are a few changes:

- The endstrut in framed got lost but is back again; there is now alao a 
location=inline option.

- Single character math as in "text $x$ text" will from now on behave 
kind of like "text~x$ text" but that ~ always felt kind of weird anyway. 
Tests on large documents with plenty math and single char cases shows 
that it works quite ok and in most cases the paragraph will have the 
same number of lines (single char moves have little impact).

- The \lastlinefit (etec) feature is now controlled by the "fit" option 
in \setupalign etc; i'm still pondering how to control the orphan 
penalty feature that has been around for a while now but never really 
configured) and if we should have a decent default for that (like 
\orphanpenalties 2 150 100 ).

- Math formula number placement (as well as alignment sinside narrower) 
has been made a bit more robust and we added some placement options that 
will be discussed in the (by now 1739 page thick) upcoming math manual.
You really don't want to know how many combinations we had to check.

In an upcoming release there might also be some new text related 
tweaking features as side effect of the math tweaks which leads to some 
experiments with the par builder (so again we got sidetracked).

Why not install-module(s), or just install?

mtxrun --script install --modules=filter,simpleslides

mtxrun --script install-modules --list=filter,simpleslides

?

I can look into that but then I need to slightly adapt it with a command 
line argument (no big deal, i just need rain outside and/or new cd's).

Not sure yet how to name the script.

Works fine at my end. I also adapted the arch AUR package to use the install-tikz option (earlier I was installing these packages by wget as part of the installation process).

Would it make sense to add a similar script to install context modules from modules.contextgarden.net?

Hi,

I uploaded a version that provides

   mtxrun --script install-tikz

that when run in the tex root (.../tex) will fetch some tikz stuff from 
ctan and puts is in texmf-modules. After installing it wipes the files 
that make no sense (or can interfere or might be harmful) but I didn't 
check that extensively. Finally it remakes the file dastabase. I don't 
know if more needs to be installed. It assumes curl to be present (as 
library or binary). It's a rather stupid script but (I guess) good 
enough for what it is supposed to do.

I can add more (like other modules) in which case it will be renamed.

Yes, but I think the default has been normal (upright), and when I
test with a minimal document here, it is still upright.

Thanks in advance,
Alex
