[NTG-context] upload

[Hans Hagen]

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).

\subject{Good riddance}

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

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.

[NTG-context] upload

[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

i actually decided on the second one but not finished yet

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

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.

[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 ...

Yes, but I think the default has been normal (upright), and when I

Many thanks for the improvements in the new release, Hans.

I have some documents, but I should be reluctant to send longs, because
I’m almost confident that my code is poorly written (to say the least).

The attachment contains a log for a 72 page document with just text
(from XML sources [XHTML generated by pandoc from Markdown file]).

[Since attachments over 100KB aren’t allowed, only the last two runs are
included in the log file.]

With current latest from today, I get:

mkiv lua stats  > runtime: 2.167 seconds, 72 processed pages, 72 shipped
pages, 33.225 pages/second
mtx-context | purged files: xml-context.log, xml-context.tuc
system  | total runtime: 8.779 seconds of 8.818 seconds

Exactly the same sources with previous latest (from 2022.12.15):

mkiv lua stats  > runtime: 2.410 seconds, 72 processed pages, 72 shipped
pages, 29.877 pages/second
mtx-context | purged files: xml-context.log, xml-context.tuc

So, the improvement is clear in current latest.

Many thanks again for the improvement,

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

I uploaded a new version of lmtx. This version uses a new counter and 
dimension model deep down (\newinteger and \newdimension) which is more 
efficient in certain cases. From the user's perspective there is no 
difference between \newcount and \newdimen although there are some 
fundamental differences. I might have overlooked a few cases where it 
does make a difference in ConTeXt (easy to handle once I know).


The test suite runs 5-10 % faster depending on the load of the machine 
and the gain mostly relates to memory access (where processes fight over 
memory and cpu cache). Of course I can probably gain more but using a 
faster machien than this 5 year old one but why waste a good machine.


Some other possible speedups are on-hold till I have better test cases.

Hans

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

I updated lmtx ... there are a few fixes for issues reported on the 
list. In the perspective of updating math the - otherwise unchanged - 
mkiv variant has also been updated a little. No new commands, just some 
(already old) experimental font related features gone and replaced by a 
combined one inspired by what we do in lmtx. In our opinion on the 
average it should not come out worse.

Sorry for complaining… :-)
no problem ... maybe we should have a wiki page for 'use this instead of 
that'


as you're playing with it ... there is a lot we haven't yet introduced 
but we will do that stepwise .. here's one


inline formulas like $(x + a + 2)$ will break across lines but 
traditionally \left( .. \right) doesn't which is why these \bigg things 
are there : manual solution for breaking inline math


however, in lmtx these do break across lines but there are of course 
still cases where the penalties injected will discourage it; there is 
agranular penalty system in place but current it is configured as 
traditional tex


now, when a formula doesn't break and is somehow wrapped it doesn't play 
that well with linebreaks but you can cheat: formulas can becoem liek 
glue where the inter atom stretch and shrink can play a more prominent 
role ... here's a test:


% turning small inline formulas into leaders to that we don't get overflows
% or excessive spacing

\continuewhenlmtxmode

\startbuffer[threshold-none]
\setupbodyfont[modern]
\setuppapersize[A5]

There is also a system like widows and orphans in the sense that one can 
set forward and backward penalties, as in:


\setuplayout[width=11cm]

\startbuffer
\dorecurse {50} {
test $\darkblue   a + #1 + b > 2$ %
test $\darkreda + b + #1 + c + d > 2$ %
test $\darkgreen  a + b + c + #1 + d + e + f > 2$ %
}
\stopbuffer

\setuptolerance[verytolerant,stretch]

\starttext
\start
\mathforwardpenalties  0
\mathbackwardpenalties 0
\getbuffer
\par
\stop
\page
\start
\mathforwardpenalties  2 -200 -100
\mathbackwardpenalties 2 -100  -50
\getbuffer
\par
\stop
\page
\start
\mathforwardpenalties  2  200 100
\mathbackwardpenalties 2  100  50
\getbuffer
\par
\stop
\page
\stoptext

but we currently don't have a high level interface for that; it will be 
part of the more general math penalties setup.


These are just a few of the things to play with.

Dear Hans and Mikael،

Thank you very much for the new upload and the new stuff for tyepsetting maths. 
I have been playing around with the features presented in the example file sent 
by Mikael, and I must say, among other things you have implemented, the 
constructs \bearkhere and \skiphere, and friends, are absolutely great, 
brilliant and so simple! I wonder why such a simple and elegant solution was 
not around before…


they were to some extend (in split=text mode) but never advocated but we 
added some to it as well as made it work with diferent alignments (most 
noticeably slanted) and number placement (overflow)



As a plain TeX traditionalist I am a little bit sad to let the \over construct 
be ditched, but my sadness did not last too long.


just think of the side effects:

   {a}\over{y} + z

y and z are combined so one need to add { }

  {{a}\over{y}}

thenm infleuncing styles becomes trickier too; the lot becomes an ord 
(ok, not in lmtx, where it becomes a fraction atom) and when you compare


  {{a}\over{y}}
  \frac{a}{b}

you even save two keystrokes -)

it's also not easy to control spacing etc because one cannot redefine 
over; actually fractions uses \U[..over|above|..] which takes two 
arguments (forward scanning)



It seems that the \choose construct has been ditched but I did not guess what 
has replaced it (I guess the reason is the same for ditching \over, since the 
construct used to be ${n \choose k}$ and this is not what one wants to have in 
a macro).


some of these were just old school simple things but we have better 
alternatives; and if not: just specify what you need and we will come up 
with something (configurable)


(of course one can just define the old schoose)

so I think that I'm only processing actual top-level paragraphs here.

There is no 'callback sequence handler' for the par builder (currently 
i see no need for it, also given the extra overhead involved) but this 
what what you can do:

I think that that code is for replacing the linebreaker entirely, like 
with using "linebreak_filter"? My goal isn't to replace the linebreaker; 
I just want to be able to inspect the paragraph before it is broken, 
without modifying anything.


as long as you return true the built in will do the work but you can 
still do the preroll so basically nothing gets replaced .. it's just a 
more natural hook;l keep in mind that if someone replaces the linebreak 
your code woudl fail to do its work anyway



What I'm trying to do *very* roughly looks like the following:

     paragraphs = {}
     attribute = 1234

     function pre_linebreak_filter(head)
     if head.id ~= node.id"par" then
     return head
     end

     local nat_node, nat_info = tex.linebreak(node.copylist(head))
     node.freelist(nat_node)

     local long_node, long_info = tex.linebreak(
     node.copylist(head), {looseness = 1}
     )

     if long_info.prevgraf == nat_info.prevgraf + 1 then
     table.insert(paragraphs, long_node)
     end

     return head
     end

     function post_linebreak_filter(head)
     node.setattribute(head, attribute, #paragraphs)
     node.setattribute(node.slide(head), attribute, #paragraphs)

     return head
     end

     function pre_output_filter(head)
     if tex.outputpenalty ~= tex.widowpenalty then
     return head
     end

     -- Pick a paragraph from `paragraphs` somehow

     -- Replace that paragraph on the page with the one
     -- from `paragraphs`

     -- Move the last line of the page onto the top of
     -- tex.lists.contributehead

     return head
     end

(The full implementation is in the module "lua-widow-control" on CTAN, 
TeX Live, and modules.contextgarden.net, or directly at 
"https://github.com/gucci-on-fleek/lua-widow-control/blob/master/source/lua-widow-control.lua;. 
It's pretty long though, so I'm just trying to summarize here.)


This works pretty well with Plain LuaTeX, LuaLaTeX, OpTeX, MkIV, and 
MkXL before the latest upload, but something broke with the latest 
upload in MkXL. I understand that I'm mucking around with volatile 
interfaces, and I have no problem making a bunch of changes whenever the 
engine/format changes; the problem is that I'm not too sure what changed 
in the engine, so I don't know what I need to change in my code.


the tricky part is probably to make sure that it doesn't interfere with 
what other functions hooked into the callbacks are doing because who 
knows what gets injected in those lists


On the to do is a to add a 'prepare' helper that adds the mandate 
nodes (par fillers etc) 


Maybe that's all that I need? If that's the case, I have no problem 
coding my own "prepare helper" if you think that it'll be awhile before 
you get around to it; the problem is that I'm not entirely sure what 
nodes I would need to add. These new nodes aren't added until after 
"pre_linebreak_filter", and they're gone after the linebreaker runs, so 
I can't inspect a "regular" paragraph to see where these nodes belong.


there will be (untested on what you do)

  tex.preparelinebreak(par)

that will add the additional stuff needed (and bark if something is 
there already).


btw, a par builder - even in luatex -

(The full implementation is in the module "lua-widow-control" on CTAN, 
TeX Live, and modules.contextgarden.net, or directly at 
"https://github.com/gucci-on-fleek/lua-widow-control/blob/master/source/lua-widow-control.lua;. 
It's pretty long though, so I'm just trying to summarize here.)


This works pretty well with Plain LuaTeX, LuaLaTeX, OpTeX, MkIV, and 
MkXL before the latest upload, but something broke with the latest 
upload in MkXL. I understand that I'm mucking around with volatile 
interfaces, and I have no problem making a bunch of changes whenever the 
engine/format changes; the problem is that I'm not too sure what changed 
in the engine, so I don't know what I need to change in my code.


On the to do is a to add a 'prepare' helper that adds 
the mandate nodes (par fillers etc) 


Maybe that's all that I need? If that's the case, I have no problem 
coding my own "prepare helper" if you think that it'll be awhile before 
you get around to it; the problem is that I'm not entirely sure what 
nodes I would need to add. These new nodes aren't added until after 
"pre_linebreak_filter", and they're gone after the linebreaker runs, so 
I can't inspect a "regular" paragraph to see where these nodes belong.


but even then one has to be careful 
where linebreak hackery is applied.


Oh yes, I'm well aware :) Earlier versions of my module would silently 
eat entire paragraphs, which was very not good. Luckily that problem is 
fixed now.


And finally, thanks for all your work with LuaMetaTeX. This new engine 
is quite nice to work with and has some pretty cool new features.


Thanks,

Thanks.

Btw, you can run with

\showmakeup[mathglue] % \mathspacingmode=1

to see what math atoms are 'seen' (the spacingmode also injects zero 
spaces) (there are other tracers too but this is the one we use most)

This is because you need to pass a list that conforms to what the 
builder expects and the callback that you use doesn't do that for you 
(after all, it also gets hbox content).


There is no 'callback sequence handler' for the par builder (currently i 
see no need for it, also given the extra overhead involved) but this 
what what you can do:


\startluacode
function builders.paragraphs.constructors.methods.preroll_a(head)
local result, info = tex.linebreak(head)
tex.prevdepth = info.prevdepth
tex.prevgraf = info.prevgraf
return result
end
function builders.paragraphs.constructors.methods.preroll_b(head)
local result, info = tex.linebreak(nodes.nuts.copylist(head))
inspect(info)
return true
end
\stopluacode

\defineparbuilder[preroll_a]
\defineparbuilder[preroll_b]

\starttext
\setmainparbuilder[default]   \input tufte \par \input tufte \page
\setmainparbuilder[preroll_a] \input tufte \par \input tufte \page
\setmainparbuilder[preroll_b] \input tufte \par \input tufte \page
\stoptext

The tex.linebreak function gets the properly prepared paragraph and can 
handle it then. On the to do is a to add a 'prepare' helper that adds 
the mandate nodes (par fillers etc) but even then one has to be careful 
where linebreak hackery is applied.

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

We're pleased to announce the first official release of the new math 
code. We're talking of:


-- a reworked math engine (which happened stepwise so some already 
trickled into previous uploads)


-- settling on one model for display math but with alignment variants as 
well as improving inline math (e.g. wrt linebreaks)


-- redoing bit of the (sub) numbering

-- improving the alignment features (the traditional one and the 
text/page mode one)


-- fixing the math font using all kind of tweaks in the goodie file

-- providing means to annotate formulas

-- we ditched support for \over simply because it is too fragile wrt 
spacing (one can \usemodule[oldmath] to get it back


-- we might move some more alien stuff to m-oldmath in due time

We paid a lot of attention to details of positioning, sizing and spacing 
of glyphs. We do have some documents in the making that describe this 
(some are in the ontarget namespace) and the second half of this year we 
use for writing a math manual (Mikael) and updating the luametatex 
manual (Hans). For sure we will run into unforseen issues, come up with 
additional things and try to please users who have demands. There are 
'hidden' features that will be revealed stepwise.


An example of some usage will be posted next.

The pragma-ade.com domain is still in transfer but the nl one should 
work fine. There is now also a https://www.luametatex.org that might be 
get some more than there is now (when i find it useful but best to have 
the domain for the ctx group).

Hi,

I uploaded a new version of lmtx (also because some users have to test 
some new metapost functionality). In the next upload metafun will use 
'double' mode (and scaledfun will be the traditional one). The 
advantage is less dager for overflows and in the meantime running in 
double mode is often also faster.

Hi Mikael (and others),

[I have not upgraded yet; version: 2022.05.02 16:19, so I don't know if 
anything has changed in the new upload, but:]

In your example if you change the tag 'hh2010' to 'HansHagen2010' or anything 
with uppercase ASCII chars, the bibliography entries will not be correctly 
rendered even if you un-comment '\usebtxdefinitions[aps]' line. [Please see 
attached output example]

This issue seems to have originated in the version after 2022.04.15 when 'tag' 
and 'field' values in publ-ini.lua were string.lower()'ed. Removing those 
statements from the file seems to be a workaround. On the other hand, if the 
tag entries are all lower-case (as they were in your example), then there 
seems to be no issue. I had reported this earlier, please see:
  https://mailman.ntg.nl/pipermail/ntg-context/2022/105585.html

Thanks,
  Sreeram

Sorry for spamming again, but I've underlooked the message from śrīrāma who

Re: [NTG-context] upload

[Otared Kavian via ntg-context]

Hi Aditya and Mikael,

Indeed in some situations it is useful to number each equation appearing in 
formulas grouped with \startcases, and one can construct a structure allowing 
this, as in the example below which is not satisfactory. I am sure Hans can 
find a better solution…

Here is a working example:

% begin math-cases-numbered.tex
\definemathmatrix[alignedcases]
[align={1:right,2:left,3:left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\definereferenceformat[informula]  [left=(,right=),text=]
\def\eqref#1{\informula[eq:#1]} 

\starttext

Using \type{\startmathfenced} and \type{\startalign} we can number each 
equation, but the left brace is too far from the formula:
\startplaceformula
\startformula
\startmathfenced[cases]
\startalign[n=3,align={1:right,2:left,3:left}]
\NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\text{in }\; 
(0,T)\times\Omega \NR[+]
\NC u \NC = 0 \NC \quad\text{on }\; [0,T]\times\partial\Omega \NR[eq:Dirichlet]
\NC u(0,x) \NC = u_{0} \NC \quad\text{in }\; \Omega \NR[+]
\NC \partial_{t}u(0,x) \NC = v_{0} \NC \quad\text{in }\; \Omega \NR[+]
\stopalign
\stopmathfenced
\stopformula
\stopplaceformula
In some situations it is useful to number each equation, for example when we 
want to say:

Indeed we could study the above wave equation with Neumann boundary conditions, 
that is when \eqref{Dirichlet} is replaced with
\startplaceformula[eq:Neumann]
\startformula
{\partial u \over \partial {\bi n} } = 0 \quad \text{on }\; 
[0,T]\times\partial\Omega.
\stopformula
\stopplaceformula

Using \type{\startalignedcases} we cannot number each equation\dots
\startplaceformula
\startformula
\startalignedcases 
\NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\text{in }\; 
(0,T)\times\Omega \NR
\NC u \NC = 0 \NC \quad\text{in }\; [0,T]\times\partial\Omega \NR
\NC u(0,x) \NC = u_{0} \NC \quad\text{in }\; \Omega \NR
\NC \partial_{t}u(0,x) \NC = v_{0} \NC \quad\text{in }\; \Omega \NR
\stopalignedcases
\stopformula
\stopplaceformula
\stoptext
% end math-cases-numbered.tex

However, some sub-disciplines like to number each case (for example, if you 
want to refer to one of them in the future).

In the old implementation, this was tricky (the equation without the equation 
number should be centered, and the equation number should be flush right). But 
I think that this should be possible with the new low-level box alignment 
macros.

Hm, but a cases environment does not provide several formulas. This is
just one formula:

\startformula
|x|=
\startcases
\NC x \NC x>0\NR
\NC 0 \NC x=0\NR
\NC -x \NC x<0\NR
\stopcases
\stopformula

and as such should have (at most) one equation number, right?

Only Hans knows if it is (easily) doable to add the possibility to add
numbers to each three lines.

By the way, thanks for testing and commenting!

Hi Mikael,

Thanks for your explanation and the example you sent about 
\definemathsimplealign (I didn’t get immediately that « sesac » in the command 
\startmathfenced[sesac] means « cases » in reverse or mirrored… I guess this is 
a wise and humourous choice by Hans :-) ).

Regarding \startcases, it seems that it is still not possible to number each 
equation, but I may be overlooking something. I’ll try a few examples and will 
let you know, as well as Hans.

Hi Otared,

At the moment I don't know how one can use the fallback system with
calligraphic/script fonts. Let me explain in a few sentences what we
changed. Now we have \mathcal and \mathscr. If the font has both a
chancery alphabet and a roundhand alphabet, the goodie file is coded
so that \mathcal points to chancery and \mathscr to roundhand. This is
the case for Lucida. So, maybe you could try to do
\setupbodyfont[lucidadk] and then try \mathscr out. Other fonts that
have both variants are stixtwo and xits. The rest have only either
chancery style or roundhand style, and there you will get what it has.
About \cal I don't know.

I think the new math alignments are still work in progress. One thing
that happens will probably go unnoticed, and that is the spacing. Hans
is playing a lot with the new atoms, and right now he is playing(?)
with construction atoms, ghosts and fences. There is one new type of
alignments, called simplealignments. We can use them for example to
collect some equations with a brace (and give the collection one
number).

Re: [NTG-context] upload

[Otared Kavian via ntg-context]

Hi Hans,

Thank you for the new upload and the improvements you mention about the 
handling of math stuff. Thanks also to Mikael for the follow up of these 
matters.

I noticed that in math mode the command \cal does not work anymore and one has 
to use \mathcal.
However in almost all of my documents I use Lucida Bright OT, and in some 
occasions I replace its calligraphic letters by the slots from Asana Math with 
the following definitions:

\definefallbackfamily[myfont][math][Asana Math]
[range={uppercasescript,lowercasescript}]

% lucida font
\definefontfamily[myfont][serif][Lucida Bright OT]
\definefontfamily[myfont][math][LucidaBrightMathOT]
\definefontfamily[myfont][sans][LucidaSansOT]
\definefontfamily[myfont][mono][LucidaSansTypewriterOT]

\setupbodyfont[myfont,9pt]

It seems that with the changes made recently the above definitions must be 
modified in order to have Asana Math show up.

So, I am asking for help from Mikael in this regard…

Also, it would be nice to have a few explanations about the new stuff in math 
alignments.

Best regards: Otared K.

Hi,

Last night I uploaded a new lmtx:

- fix in new strut handling
- zint support improved
- some more math font tweaks (mikael will enlighten *)
- math alignment spacing nornmalized (mikael will explain *)
- new simplealignment environmet (mikael will document *)

We're now playing a bit more with combining graphics and math 
(educational usage)

[Hans Hagen via ntg-context]

Hi,

I pploaded a new lmtx (no rpi 64 bins yet, one can pick these up from 
the build in a few days).


Apart from a few fixes (older side float issue, some recent special rule 
related things) the only new thing is 'low level anchoring'. More can be 
found in ontarget.pdf (ontarget-anchoring.tex). It basically boils down 
to boxes listening to source, target and anchor keys, as in:


\vbox
source 123
\bgroup
\offinterlineskip
\blackrule[width=4cm,height=2cm,depth=0cm,color=darkred]\par
\blackrule[width=4cm,height=0cm,depth=1cm,color=darkblue]\par
\setbox\scratchboxtwo\hbox
anchors "0004 "0001
  % anchor "00040001
target 123
orientation 1
{\blackrule[width=2cm,height=1cm,depth=0cm,color=darkgreen]%
 \hskip-2cm
 \blackrule[width=2cm,height=0cm,depth=1cm,color=darkyellow]}%
  %
\smash{\box\scratchboxtwo}%
\egroup

the mentioned document describes a bit higher interface (plugs into 
layers) .. all kind of experimental and meant as teaser for users who 
like low level stuff (playground).


I also made it possible to use context \frules with leaders as in:

test \leaders \frule height 6mm depth 3mm radius 1mm\hfill test

\startuseMPgraphic{demoleader}
fill
unitcircle xysized (RuleWidth,RuleHeight+RuleDepth)
withcolor RuleColor ;
\stopuseMPgraphic

test {\red \leaders \frule
height 6mm
depth  3mm
typemp
data{\includeMPgraphic{demoleader}}
\hfill} test

\startuseMPgraphic{demoleader}
drawdblarrow (0,RuleHeight) -- (RuleWidth,RuleHeight)
withpen pencircle scaled  RuleThickness
withcolor RuleColor ;
\stopuseMPgraphic

test {\red \leaders \frule
height  1mm % we need at least some dimensions
typemp
line1mm
data{\includeMPgraphic{demoleader}}
\hfill} test

(leaders can have boxes, rules and also glyphs)

In principle we can also have adaptive images (basically scaling) so I 
might make an example of that later (when i need it).


Of course I'll fix things I broke this time,

Hans

Ok, but that's what the context runner is for, not? It's smart and
knows when it's hitting the last run and if there are still
unresolved issues, it could then report the correct return value to
the environment. The runner is responsible for the final return
value, not the individual context run AFAIK.

Ok, that works, great news. So if I understand you correctly,
there's no command to enable them *all* at once? Frankly, I'd expect
\enabledirectives [logs.errors] to enable them all (including the
correct return value), but apparently it only enables the reporting
and doesn't affect the return value.

That begs the question: Which error directives are available (so I
can manually enable them)?

Side note: A missing font is not an error:

  \enabledirectives [logs.errors]
  \definefontfamily [foo] [serif] [no font here really]
  \setupbodyfont [foo]
  \starttext foo \stoptext

But I guess that's just not supported.

I did some more checking. It seems to return 1 on *some* errors, but
not on all the ones supported by --errors. This example e.g.

because these are not errors in the sense of 'quit' ... for instance 
missing references can be resolved in a second run


you need to be explicit:

\enabledirectives [logs.errors={missing references,missing characters}]

Apple Preview works without any problems, with a quick test.

It forces a popup dialog for “user password” on opening when that is set, and 
with 

  context .. --permissions="-print”

it shows an "owner password" dialog before allowing to print

[NTG-context] upload ... new feature

[Hans Hagen via ntg-context]

Hi,

This time the lmtx upload has a (for some maybe) interesting new 
features: runtime pdf encryption.


context
   --ownerpassword=foo
  [--userpassword=bar]
  [--permissions="see context --help --expert"]

One can also use the document banner line, like:

% ownerpassword="foo" userpassword="" permissions="print,extract,quality"

Now, this is a feature that relies on the viewer to deal properly with 
it as we only support the not depricated method (why bother with the old 
stuff).


acrobat  : it took some effort (and trial and error) to make that one 
happy but it seems to work ok


summatra : the one i use, it works ok in the latest greatest (i use 
3.3.13418)


mutool   : okay but sometimes with a warning (i have a workearound but 
not enabled it because i consider it to be a bug)


qpdf : happy but check gives a permissions warning (understandable 
as that is a real mess)


firefox  : opens ok in the latest version (pdf.js)

chrome   : can't handle the revision level we use (the rest is 
depricated so i consider it a lack of feature for now)


edge : idem

okular   : my (windows) version is too old

xpdf : not up to it yet

foxit: (i never use it, but tried ... it's code seems to be what is 
used in chrome) doesn't work with this revision


I would be surprised if the native apple viewer works but I can't test that.

Given earlier pdf threads, I wanna check with Michal Vlasák what can be 
improved.


Performance is okay, the luametatex manual takes 1% more runtime and 
that's within the runtime measurement margin that I use. I didn't test 
with external images yet but will do that so don't expection yet. It 
will probably take a few months to reach a stable state anyway. (But ... 
afaiks tikz pdf generation, which is also somewhat alien to context, 
seems to work).


Hopefully I didn't mess up the unrelated code,

Hans

Re: [NTG-context] upload

[Jairo A. del Rio via ntg-context]

Hi, Hans. I've got a question. Negative steps are treated as positive:

\starttext
\expandedloop 10 0 -2 {\the\currentloopiterator\ }
\stoptext

gives

0 2 4 6 8 10

Is this expected behavior? If so, it would be fine to have something more
alike to MetaPost's "for ... step ... until" loop. Thank you in advance.

Regards,

Jairo

[NTG-context] upload

[Hans Hagen via ntg-context]

Hi,

a new upload

- some keywords renamed in the engine and therefore more split between 
mkiv and lmtx (hopefully i included all files) .. if something doesn't 
work any more it might be because i missed a rename.


- i finally decied that it does make sense to have native loops at the 
primitive level (after all, metapost as macro language also has them) 
and although much is possible in macros it doesn't mean we have to do it 
the (often ugly and showing-off-by-abusing-side-effects way).


We have just a constructor:

  \unexpandedloop  1 100 1 {.}

and a fully expandable one for e.g. use in \edef:

  \expandedloop1 100 1 {.}

plus an also fully expandable one for anywhere but with potential side 
effects (out of order local loops):


  \localcontrolledloop 1 100 1 {.}

complemented by a few status primitives (integers, use \the or \number 
to serialize them):


  \currentloopiterator
  \currentloopnesting

and a quitter that aborts at the next iteration:

  \quitloop

as usual it's experimental for a while. Among the rationales are 'less 
tracing clutter', 'performance' and 'more natural primitive tex coding' 
(but that one is personal).

Hi!

As I wrote, I do not use the quadruple primes (I used your file), but
I must confess that I'm impressed that you fix it so quickly. :)

In any case, a big thank you for fixing the primes in the libertinus font!!

generating pdf files that can be compared. No date as a bad idea anyway.

\setupinteraction[title=My Title]
% \enabledirectives[backend.date=2034-06-07]
\enabledirectives[backend.date=no]
\enabledirectives[backend.trailerid=no]


I checked the backend code and some of the related os functions. I put
together a patch that hopefully fixes some stuff and doesn't break
anything. The changes:

1) Dates parsed by ConTeXt (function converters.totime), such as those
that are input to backend.date, now allow specifying seconds and time
zone information. If there is no timezone the datetime is presumed to be
in local time, otherwise the datetime is offset by the local / specified
time zone difference (because ConTeXt outputs these dates as local times
with local timezone). Additionally both "T" and " " are now allowed as
date/time separator characters. Thus dates output by ConTeXt can be also
fed in.


i made the parser a bit more tolerant

"1234-12-30"
"1234/12/30"
"1234-12-30 23:45"
"1234-12-30 23:45:16"
"1234-12-30  23:45:16"
"1234-12-30T23:45:16+01:00"
"1234-12-30 23:45:16-02:00"
"1234-12-30 23:45:16+05:00"
"1234-12-30 23:45:16 05:00"
"1234-12-30  23:45:16  05:00"

(I'll send you the file to check/test)


2) Fix the os.timezone function. Previously, it could be wrong around
midnight, which I discovered only by chance. The trick is lifted from
http://lua-users.org/wiki/TimeZone, which I hope is OK. The before and
after (I am at +02:00):

 os.localtime()  2021-10-22 01:44:24
 os.now()2021-10-21 23:44:24
 os.timezone(true)   -22:00


 os.localtime()  2021-10-22 01:46:23
 os.now()2021-10-21 23:46:23
 os.timezone(true)   +02:00


shouldn't we also offer a -02:00 ? (relative)


I also extended the interface of os.timezone to accommodate 1), but as
this is probably a very public interface, I am not sure if these changes
are OK. If more changes to the interface can be made, I propose to get
rid of the delta parameter, since it seems like a remnant from the past.


maybe later, i need to check other files


Some caching can also be introduced, but I again wasn't sure if this
even would be the final form of the function, so didn't do anything in
that sense, yet.


i'll adapt it to that


3) Don't use %X in time formats. It is specified to be platform
dependent and we want %H:%M:%S everywhere. Also, it would be nice if
lpdf-xmp.lmt would use the os.fulltime() function to format dates (like
back-exp.lmt does), but there are multiple dates with different formats
and purposes and it is probably too late to change now.


(probably not that harmfull on the platforms we support)

the reason for different times is that i never liked the timezone in 
regular date/time (so only the mandate one had it) but in the end i 
don't care that much about times/date i never look at (i admit that i 
never consult any of this pdf meta data)



4) I changed the os.fulltime function, that returns date + time + local
time zone to output the _local_ time instead of UTC time. This is AFAICT
the right way to do times. The PDF spec says:

 If no UT information is specified, the relationship of the specified
 time to UT shall be considered to be GMT. Regardless of whether the
 time zone is specified, the rest of the date shall be specified in
 local time.

 EXAMPLE: For example, December 23, 1998, at 7:52 PM, U.S. Pacific
 Standard Time, is represented by the string D:199812231952-08'00

Hi Michal,

I haven’t found the time to check this, but this is pretty much what I
wanted: being able to set other timezones than the local one.

Many thanks for your help,

Many thanks for the new version, Hans.

Is there a way to add time and timezone in backend.date?


Pablo : transparencies should work again (wrong alias fixed).


Many thanks for this fix too.

Sorry for insisting, but could you check what is wrong with an extra
blank space in rotated imposition
(https://mailman.ntg.nl/pipermail/ntg-context/2021/103909.html)?

.. it was not really a minimal example ...

\showframe

\starttext
\topskip4cm
\rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page


\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\page


\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\page
\stoptext

so, you need to wrap it, like

\startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup
\startpagemakeup \rotate[rotation=90] 
{\externalfigure[A3page.pdf][page=1,width=\textheight]}\stoppagemakeup
\startpagemakeup 
\rotate[rotation=270]{\externalfigure[A3page.pdf][page=2,width=\textheight]}\stoppagemakeup


and not make it 'sort of text that breaks or not across the page'. Now 
it is an interesting question why ... (spoiler: nice animation:)


\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{

\rotate[rotation=#1]{\externalfigure[A3page.pdf][page=1,width=\textheight]}
}
\stoptext

so we probably cross some threshold with some angles and because these 
are basically lines, we then get an interplay woth topskip, maxdepth etc 
(which normally goes unnoticed)


the good news is that you can play with it because rotate is normally 
configured for inline usage (so we get depth and height) you can use the 
location parameter to do otherwise:


% normal default depth fit broad high middle

\starttext
\topskip4cm
\dostepwiserecurse{0}{360}{1}{

\ruledhbox{\rotate[rotation=#1,location=high]{\externalfigure[A3page.pdf][page=1,width=\textheight]}}
}
\stoptext

irr it's actually shown somewhere in a manual but the source also has this

% \dostepwiserecurse{0}{360}{10}
%   {\startlinecorrection[blank]
%\hbox
%  {\expanded{\setuprotate[rotation=\recurselevel]}%

so, not a bug but a features (that code hasn't been touched for ages, 
apart from maybe some lmtx interface adaptation), and if it's not in the 
wiki .. you know what to do now

anyway, as you desperately need these quads (why check otherwise), 
adding this to the lfg blob helps:


local four = characters[0x2057]
if four then
local one = characters[okay]
local owd = .75*one.width
local off = .6*one.height
four.width = 4*owd

}
else

and no one will notice (unless you wikify al this)

Hi!

Thank you Hans for the very quick fix on the libertinus font!

It works very nicely. I played with the test file you sent me, and I
find that in the .lfg file, the up parameter set to 0.06 instead of
0.1 looks better to me.

/Mikael

PS I do not use them, but I noticed that the quadruple prime f
still uses small primes.

Hi,

I cleaned up some more backend code.  There were some mails about dates 
and such and although the date field in setupinteraction works ok a more 
drastic overload is doen with directives. The reason is that the fact 
that we can set the date (and traler) is only because it permits 
generating pdf files that can be compared. No date as a bad idea anyway.


\setupinteraction[title=My Title]
% \enabledirectives[backend.date=2034-06-07]

\enabledirectives[backend.trailerid=no]
\starttext

\startTEXpage
\blackrule[height=1cm,depth=0cm,width=4cm,color=darkred]
\stopTEXpage

(there always were command line options for it)

More interesting is asome new experimental code:

\starttext

\dostepwiserecurse{40}{110}{2}{
\startTEXpage[offset=4mm,width=#1mm,align={stretch,normal,tolerant}]

\updateparagraphpenalties
\samplefile{tufte}
\par
\stopTEXpage
}

\stoptext

it's an addendum to the widowpenalties and clubpenalties introduced by 
etex but this time it's horizontal; the orphan penalties will be 
inserted before spaces (aka spaceskip, xspaceskip and zerospaceskip 
glue) so in this case 4000 between the last two 'words' and this 
trickery can be used to make sure that the last line is not too short


\orphanpenalties 4 4000 3000 -12000 1000\relax

is also intereting

it's work in progress (i need to play more with it and figure out nice 
values for context) .. there might be more such 'simple' useful tricks

Of course we do, especially after Hraban recommended the 2021-10-10 tree last 
week.

Just one question:

LMTX comes with an empty texmf-modules tree.
Are we still supposed to copy the context version?

There have been updates to letter, filter and some others lately.
That means we have to update the context tree as well.

Do you plan to include this tree in the future?


at some point yes, but then we can also sync from the garden server (on

Hi Hans,

I’m afraid that viewerlayers have issues now.

I hope I’ll find some time soon to write a minimal sample.

Many thanks for the new latest, Hans.

The following sample shows an issue with "newcmmono10-bolditalic.otf":

  \mainlanguage[agr]
  \definefontfamily[another][rm][Another]
[tf=file:newcmmono10-boldoblique.otf]

  \stoptext

I’m afraid that there is no "newcmmono10-bolditalic.otf", but
"newcmmono10-boldoblique.otf".

The following patch fixes the issue:

Indeed it looks ok. (Years ago I had a talk at bachotex showing slightly 
boldened modern so it is already possible in context with the normal lm 
fonts .. it's how we do full-bold math).


I might but wonder why the book files are so large (it would add 
significant to the currently small lmtx distribution so maybe wait till 
a next version .. i'd not include the 8 pt anyway).

Re: [NTG-context] upload / some new math stuff

[Fabrice Couvreur]

Hi Hans,
I am not a font specialist and I use pagella and modern.
I'm curious so I installed this new font in
/home/viserion/LMTX/tex/texmf/fonts/opentype/public/newcomputermodern
I tested your file and I get the following message
Thank you Fabrice

This is
normally done by loading special math fonts into the math family slots.
Your font

Hi!

The book version looks nice, indeed! (I am one of those who still use
the MetaFont version of computer modern (in LaTeX), with some
parameters set so that it becomes less thin. Looks very nice when
printed. I guess this book version will also look better, and replace
the MetaFont setup!)

Is there an option available to always get upright integrals?

[NTG-context] upload / some new math stuff

[Hans Hagen]

Hi,

I played a bit with these newcomputermodern fonts. They are extended 
versions of latin modern and come in:


- 10pt (serif, sane, mono, math)
- book (serif, sane, mono, math)
-  8pt (partial)

I made a typescript for the 10pt regular and book (as I see no reason to 
configure 8pt).  So, assuming that one installs these fonts:


\setupbodyfont[newcomputermodern-book]
\setupbodyfont[newcomputermodern]

should work ok. The book variant is quite nice. I didn't look into the 
provided math alternates (context supports that but I didn't define them 
for this font ... input from math lovers is welcome).


Now, this font also implements, as cambria does, upright integrals and 
as that has comes on my radar every year when I ponder these integrals I 
decided that it was about tiem to deal with it properly. It is no big 
deal to implement them gropwing (after all one can see them as left 
delimiter) but the main issue are these super and subscripts.

This \Umathadaptsize is a bit like the limits related suffixes (and uses 
the same scanner logic). It basically flags an operator as something 
that should grow cf what follows. I can add some fine tuning if needed

(I might also extend another mechanism to deal with it but putting

Of course only a few fonts provide these upright growing integrals 
(makes me wonder about summation and product).


Concerning the newcm fonts: for some reason the book variants (otf 
files) are about twice as large (in filesize) but what we use (cached) 
is the same size (only bboxes differ) so there is something fishy in the 
otf. I can imagine that at some point we add the 10pt/book ones to the 
standard mkiv distribution and maybe only the subset to the lmtx 
distribution but for now these book ones are too big for that, but it 
all depende on them being used.


Happy testing (hopefully there are no side effects).

This is from some minute ago (Date: Tue, 15 Dec 2020 20:15:33 GMT).

I guess this might be the reason for an oudated brand new install.

I think there might be an issue here.

I'll check it when I've finished what I'm doing now (some more mp stuff).

Re: [NTG-context] upload / metafun

[Otared Kavian]

Hi Hans,

Thanks for the new upload. 
With your comments, I understand that, following the discussion with Aditya, 
when using the new version I should not define in Metafun a new function named
dotlabel
in order to have a square dot… Actually I called it mydotlabel in order to be 
able to change the shape of the dot, so I will be on the safe side when I can 
download the new version.

However after running install. sh on MacOS, I still get current version: 
2020.12.10 22:26, even after removing the .tma files.
So I guess I have to wait a little bit for the new version to be upoaded.

Best regards: Otared

[NTG-context] upload / metafun

[Hans Hagen]

Hi,

I uploaded a new lmtx. This time some work has been done at the metafun end.

At the tex end we're working on some overload protection mechanism which 
involves tagging many macro so that will take a while (most tagging is 
done but checking left over cases take time).


So, I wondered if we can do something similar in metapost: flag macros 
and variables in order to issue a warnings when a dangerous overload 
happens.


The current lmtx has this as an experiment: primitives, permanent, 
immutable and mutable (so far); you can look at the *.mpxl files to get 
an idea. If you say for instance


path fullcircle;

there will be a warning

metapost> overloading immutable 'fullcircle'

or when

\enabledirectives[metapost.overloadmode=error]

has been given you get an error.

The implementation is rather simple and non intrusive and differs from
the one in tex. There it is tightly integrated for all kind of reasons 
(millions of macro definitions per run so efficiency matters). Also, in 
metapost variables (tags) can have complex name constructions and we 
only test the top level. When a overload happens (overloadmode internal 
<> 0) a lua callback takes care of it.


A side effect is that we can query all hash entries and check for 
consistency which is what i've done and am doing now. Of course that can 
introduce issues ... just that you know.

yes, i'll make new zip btu i also found out that the build server is n't

Re: [NTG-context] upload

[Otared Kavian]

Hi Hans,

On MacOS X I obtain the same error when doing:
context --make --all
(or mtxrun --make --all).
The error is

csname overload > fatal error, protection level 4, control sequence 
'textcontrolspace', properties 'immutable', file 'enco-ini.mkxl', line 315


Best regards: Otared

Hi

on linux I get:
csname overload > fatal error, protection level 4, control sequence
'textcontrolspace', properties 'immutable', file 'enco-ini.mkxl', line 315

wiped cache; run mtxrun --generate without problems; but context --make has
this error.

Do I miss something?

Thanks
Christian

Hi Hans,

I’m afraid that there is an error that prevents the creation of the
format file:

loading > ConTeXt Encoding Macros / Initialization

csname overload > fatal error, protection level 4, control sequence
'textcontrolspace', properties 'immutable', file 'enco-ini.mkxl', line 315

Just in case it helps,

Pablo
