Thank you!
And when would you suggest what?
A float I’d use only if I need caption/numbering or the floating feature.
When I tried line correction, it never helped; probably I used it wrong
(e.g. around section titles).
I wanted to document it, but can’t find it in the sources:
The definition is in spac-ver.mkxl.
Thank you!
So, "context --find" does not what I thought it would.
AFAIR the find option searches only the manual sources.
Looks like it. So I should use grep (mtxrun --script grep).

[NTG-context] context editor support / syntax highlighting for Pulsar
Hi Hans (et al.),
find attached a slightly extended version of the "interface" script that
can also generate the list of commands in cson format for Pulsar/Atom.
It just creates a basic list of commands for syntax highlighting; for a
complete plugin, "grammars" and "settings" are missing, see
https://codeberg.org/fiee/language-context
(Yes, this approach is oldfashioned and a plugin could do a lot more,
but I don’t speak TypeScript.)
The generated cson file is for "snippets", like in:
https://codeberg.org/fiee/language-context/src/branch/master/snippets/language-context.cson
There, I added information from the interface files and also from the
wiki, if existing. I don’t know how to do that in the lua script.
---
function flushers.pulsar(collected)
for interface, whatever in next, collected do
local commands = whatever.commands
local environments = whatever.environments
local result, r = { }, 0
r = r + 1 ; result[r] = "'.text.tex.context':\n"
for i=1,#commands do
r = r + 1 ; result[r] = format("\t'\\%s':\n",commands[i])
r = r + 1 ; result[r] = format("\t\tprefix:
'%s'\n",commands[i])
-- can we have some information?
--r = r + 1 ; result[r] = format("\t\tdescription: 'level:
primitive; interface: i-tex.xml'",'')
-- no URL if command starts with "stop"
r = r + 1 ; result[r] = format("\t\tdescriptionMoreURL:
'https://wiki.contextgarden.net/Command/%s'\n",commands[i])
end
io.savedata(format("language-context-%s.cson",interface),
concat(result),"\n")
end
end
---
Also, the "en" interface is empty, everything is in "common", so the
iteration over interfaces makes no sense here.
Actually, Atom/Pulsar could work with a tree sitter parser
(https://github.com/pmazaitis/tree-sitter-context), but I don’t know how
to use it.
[TextMate]
For TextMate and other editors that use TM bundles, it might make sense
to update https://github.com/pgundlach/context.tmbundle
At least the list of commands could be automatically converted from the
interface files, but it’s more involved than what mtx-interface does.

Moreover this command can be used by people who want to transform the

you cna be more ambituous:
\im { C \of (\openinterval{a,b}) \neq C^^2 \of (\interval{a,b}) \neq
C^^2 \of \interval{0,1} \neq C\of(\Omega) \neq 풞 \of (\Omega)}

so we can really get rid of a lot of math
as one can see in the attached output which is very useful for the blind
using an audio software.
yes, although unfortunately unicode never bothered to add some handy
stuff for that (while if did for other comparable things) but we'can get
around that
I now assume that you are willing to come up with the french

serious german context math users, as I wouldn't trust Hraban and Thomas
on doing this?

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 ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___

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
