[NTG-context] New example with both sides margin

[Ursula Hermann]

Dear Pablo,
Here is my example:
\setuppapersize[A4]
\setupbodyfont[termes, 12.50pt]
\setuplayout[backspace=2.9cm,
 width=fit]
\ininnermargin{\blackrule[color=black, height=0.10ex, width=1cm]\\{3.2.2}} 
\dontleavehmode \blackrule[color=black, height=0.10ex, width=13.50cm]
\showframe
\starttext
Me\par
\blackrule[color=black, height=0.10ex, width=13.50cm]\dontleavehmode 
\inoutermargin{\blackrule[color=black, height=0.10ex, width=1cm]\\{3.2.2}} \par
Me
Many thanks for your help.
Uschi Hermann

[NTG-context] new context option

[Hans Hagen]

Hi,

As I needed to check some commands i added this:

   context --find="%\starttabulate"

which will (should) give a list of lines/files in the documentation 
where this command is used.

[NTG-context] New upload doesn't work on macOS 10.13.6

[Ralf Heinrich Arning]

Hi list,

after having tried to update with the new upload, ConTEXt doesn't run anymore. 

According to the output the new version requires a more recent system. I still 
use macOS 10.13.6 (High Sierra).

This is what I get:

=
context TestCode.tex
dyld: lazy symbol binding failed: Symbol not found: chkstk_darwin

===

Trying to install again, I get:

What can I do?

Do I have to reinstall an older version? How can I do this?

Desperately,

Ralf

Hi,

new upload with packed itemize fix .. hopefyully no side effects of some 
work in progress (but no crashes in test suite so likely ok)

[NTG-context] new upload

[Hans Hagen]

Hi,

I uploaded a new lmtx (some new - experimental - things will be 
explained after the ctx meeting), but there's one thing that is somewhat 
important.


In addition to the built in units we can now have so called user units. 
There is some more info about this in the lowlevel-registers manual. One 
of the predefined units is 'uu' with an associated \ununit (dimension) 
variable and it's is also interfaced to metafun. That means that when 
you use uu in metapost graphics you have to make sure that you save the 
meaning and/or numeric uu now.


The idea is that just as in mp one can say 20xx with xx being a (sort 
of) unit, one can do the same in tex. Think of


\newdimension \MyUnitA  \MyUnitA 1.23pt

\pushoverloadmode % just in case
\newuserunit\MyUnitA ua % binds the unit to the variable
\popoverloadmode

x\hskip 10ua\relax x

The units starting with 'u' are considered user units but be carefulk 
with other combinations as we have (and will have more) built into 
context ones, like


pi : pi for Mikael
ft : foot for Alan
fs : (global body) font size
tw : (layout) text width
th : (layout) text height
hs : (current) hsize
vs : (current) vsize
cd : (when set) column distance
cw : (when set) column width
cx : combination cell width
uu : user unit (\METAFUN)

So Mikael can now have

  test \hskip 3pi\relax test

and Alan can have

  \setuplayout
[width=1ft]

to be consistent with inches.

The reason why we have this mechanism is that it provides a level of 
abstraction. It might evolve over time but don't expect the 600+ units 
possible to show up because one needs sensible shortcuts. Already built 
in unit always win and you cna only bind to already defined quantities.


Here's one for those who want to go beyond the normal:

\newdimension \FooA   \FooA 1.23pt
\newdimen \FooB   \FooB 12.3pt
\protected\def\FooC   {\the\dimexpr\FooA +\FooB\relax}

So you can now figure how 'cx' is defined in a dynamic way.

[NTG-context] new upload

[Hans Hagen]

Hi,

In todays upload there is a follow up on a new feature that is already 
present in the previous upload (but that was not yet advertised):


  context --parallel test1.tex test2.tex test3.tex

  context --parallel --pattern=test*.tex

  context --parallellist myfile.cmd  (filters context processing lines)

  context --parallel test1.tex test2.tex test3.tex --terminal

The --parellel feature will run in parallel, By default upto 8 jobs but 
you can specify less or more depending on your hardware but on my 
machine this is reasonable.


See workflows-parrallel at the end for more info. That one also mentions 
the new --forceinput flag which makes that when these


  context foo-1.tex --mode=m-1 --forceinput=whatever.tex
  context foo-3.tex --mode=m-3 --forceinput=whatever.tex

are run in parallel there is no clash in tuc/pdf. Of course not all 
scenarios might work out well. Commandline arguments given are passed on 
to the different jobs but it's good enough for the purpose I have in mind.


fwiw: a single pass teststuite run (some 1950 files) goes down from 1350 
to 700 seconds but another run with 1200 complex xml documents goes 4 
times faster. In the end this is way cheaper than updating a 5 year old 
dev machine (a new one would run about twice as fast which would bring 
about the same gain).


Hans

ps. Because tex is a memory intense application it doesn't scale with 
the number of cores unless one has the latest greatest fast memory as 
well as generous cpu caches. There's only so much one can do in the code 
base about it.

[NTG-context] new upload

[Hans Hagen via ntg-context]

Hi,

No functional changes this time:

- some more consistent usage of new primitives instead of helper macros, 
also a bit of a look and feel related effort as well as getting even 
less tracing clutter (the kind of changes for Wolfgang to check -)


- as aside effect there is some performance gain (there is not that much 
more to gain now unless we go ugly); this all depends on usage of course


- at some point some of the more obscure middle level helpers (dating 
from mkii) might move to a module as i don't think anyone uses them in lmtx


There are quite some files affected (all is tripple checked but who 
knows). If there are issues, they should be easy to fix.


We're now moving into page builder (another side effect of math tuneup) 
mode and have some new features coming there.


Hans

[NTG-context] new version

[Hans Hagen via ntg-context]

Hi,

I uploaded a new lmtx version (so the next series will be luametatex 
2.10.10). Although Mikael and I are still in improving math mode, we 
side tracked a bit to the par builder (better breaking of math etc). In 
the end some experiments there turned features.


(1) We already had a more granular par builder but that was never really 
enabled. From now on you can do that with


\setupalign[granular]

After quite some tests and careful inspection of outcome we think that 
the results look better, which is why if could become a default. The 
main impact is a bit more even spacing between neighbouring lines, 
because we operate in five instead of three ranges of primary badness now.


(2) As side effect of (3) initialization of expansion (as well as 
compression and protrusion) is delayed till it kicks in. This means that


\definefontfeature[default][default][expansion=quality]

has become cheaper and might as well become the default.

(3) The biggest new feature (already known to some of you as we chat 
about it) is that in addition to the (upto three) passes that create a 
paragraph we can now have extra ones. This is discussed in 
lowlevel-lines.pdf (preliminary). The second pass is the most important 
one (it uses hyphenation but not yet emergency stretch) and, based on 
criteria that can be set, between the second and third pass multiple 
attempts can be triggered.


So, for instance one can start careful (pass one), less careful (pass 
two), test all kind of variants (pass 2 subpasses) etc. These subpasses 
can have different tolerances, demerits, expansion, etc and quit once 
soem criteria are met.


The problem here is: what makes good defaults. Therefore we have some 
tests definitions added (see spac-pas-tests) that we hope users will 
test on realistic documents.


In case one wonders: performance is quite okay and you won't notice much 
difference on a reasonable run. Also, when you normally use expansion 
for a whole document, you can now let it kick in more selectively. As a 
result a run can be faster and the resulting pdf file can be smaller. 
This feature kind of assumes (1) above.


(4) There's also a new feature for optional content: you can have marked 
sections in a paragraph that can be enabled or disabled in attempts to 
get better output. Of course one can wonder it this is useful but it was 
one of the older todo's. When it is considered usefull it can evolve.


(The lowlevel-lines manual is work in progress and in a few weeks we 
will pick up on that.)

well, if you install a new module th eold module can interfere; nothing

Please don't do this! I fear it will break my habit of keeping older versions 
that worked for me. As a safeguard against things that are broken and will have 
to wait when repaired!

I regard it good practice to have README, LICENSE and VERSION files in 
the root. A public git repository without these is incomplete, and if we 
use the zip/tgz packaging of platforms like github or gitea (codeberg), 
we can’t exclude them.

The installer script could just ignore/delete them.
I currently wipe them but it's extra work and who knows what shows up in 
the future.

"mtxrun --script install-modules --install simpleslides" (without "t-")

But either the module scripts should re-pack tgz archives or the 
installer must learn to handle them.
There is code for unpacking gzip and tar but I don't think we should 
start mixing formats and zip is kind of what we always did.


The modules are in the imp files (mentioned when loaded) but the urls 
are sort of abstract (and resolved in the installer).


I've added an option to directly pass an url but I suppose that is only 
for testing. After all, we expect some quality checks and thats what the 
garden does.

but as said, it's only for testing (or for modules not yet mentioned in

Keep in mind that no files are deleted. When all modules are 
consistently packages I can make a 'remove old' feature.

[NTG-context] new module installer and .tar.gz compression

[Pablo Rodriguez via ntg-context]

Hans,

many thanks for the new script to install modules in LMTX.

I forced a new release of handlecsv
(https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=86).

I provide the contents with a git address, so I cannot choose which kind
of compression the code will have.

Since imports from git use .tar.gz, these modules cannot be installed
with the script (which seems to expect .zip compression exclusively).

Sorry, but I don’t know how to force git urls to be added as zip
packages in https://modules.contextgarden.net.

Many thanks for your help,

Pablo

The moral of the story is that we all missed something by not attending
BachoTeX - as is the case every year. One should note Hans' reference
to the gala dinner, which is better characterized by an excess of
dishes of food than by an excess of alcohol.

We have an opportunity to make up for this missed occasion this year by
attending the annual ConTeXt meeting. Of course, these two meetings are
complementary and ideally one should aim at attending *both*.

As to the Dutch left and right thumbs, the French word is also "pouce"
for the length of an inchworm. My question is, what is the appropriate
unit for inching forward or inching along? Would this be one inch per
fortnight?

Hi Hraban,

Attached a picture of the edithorial which is now in posession of the 
one who's name comes closest to it. A bit like the 'meter' makes Paris 
famous, this one will put the (engineering) university of Lund on the 
map. Up to the reader to figure out the magick slot and workings. Yet 
another one of Willis masterpieces of woodwork and packaging.


If Alan had been present we might have gone for measuring toes intead of 
thumbs but then we'd end up with 30mm median I guess. Actually, by going 
discrete we also made sure thet people with different left and right 
thumbs (we hadn't anticipated that actually) were satisfied, something 
that was demood live on camera. It's in de details.

During the meeting (aka conference) and in preparation Mikael and I were 
on 0% alcohol beers, so effectively that unit would then be a multiplier 
of zero, but I'm sure you can find a usage for that.


I forgot to check what the pct was of the wine at the (as usual) huge 
dinner but I can check the bottle I got from DT. Talking percentages, 
maybe some high res percentage primitive is interesting (we have 
.4\somedimen but for counters one needs to cheat a bit).


Actually we were talking of some 'eps' and interval based comparison in 
order to avoid small issues with accumulated rounding (in the sp range) 
but that is a side track.

It was a three person presentation on multiple laptops and phones, so

The problem with introducing the theodore is that it introduces another 
'male name' unit while actually the new ones got 'female names' in order 
to counter the didot and cicero (and dk although we considere that a 
neutral unit), which was one of the projects objectives.


Okay, we can from now on assume the 'mm' to be the Mojca which is also 
more officient: 4 mojcas instead of 4 millimeters. It's a downward 
compatible change (only in the documentation). Then we can introduce the 
tr as precisely 5 es, a kind of snaposhot unit, whgich makes me wonder, 
as the theodore eventually will come close to a foot we might have a 
\thfactor then that starts out at 5. We can decide at the ctx meeting.


(In case one wonders: because internally tex works with fractions mm/cm 
and ts/es (/tr) make sense.)


(As explained during the presentation, adding units to luametatex is not 
really putting a (performance) burden on this engine. In pdftex and 
luatex it would have an impact, although in luatex somewhat less because 
we prioritize our favourite units anyway.)

That is incorrect.  Feet is an establish and proper unit of measurement, which 
consists of 12 inches.  It is used by, at least, several hundred million 
people.  It can be said that the ability to grok and manipulate fractions has 
many benefits, which the metric system sorely lacks.
Sure, but it's not a unit in tex like 10ft so reporting 19 feet looks a 
bit odd for the (majority) texusers who dont'use feet. (we have mm and 
cm but not in and ft). I suppose yards could also have been used but 
probably points out more prominently the limitation.


https://nl.wikipedia.org/wiki/Voet_(lengtemaat)

An amsterdam voet being somewhat smaller actually would have made 20 
which is a nicer number and also fits the base 20 inuit system discussed 
a few weeks ago.

Honestly, I don't know how Knuth resisted putting this in plain TeX.

Plain TeX is a format so ther it would be easy, just define

\newdimen\potrzebie  \potrzebie = 422042sp

but for a real unit you need to adapt the original engine and that will 
not happen because it's in bug fix only mode.


Anyway, you can try it in lmtx:

\startTEXpage[offset=1dk]
\number\dimexpr1dk
\stopTEXpage

As introduced in:

Like the ts is makes a nice offset.

The inch is properly defined as *exactly* 2.54cm.
So the foot is a proper unit defined as 12*2.54cm.

Manipulating fractions, I stated, is the entire point of Imperial
measurements.

Now go figure: Physical Review Letters once objected to my publishing a
graph without units on the abscissa. I satisfied the editor by adding
$[m\times m^{-1}]$ (my graph was in radians).

Well, the Polish oversight seemed to a agree and the team was awarded by

less than 4in ^2.


But, if you're really into old units we can measure your feet and 
replace "max 19 feet" message by "max 20 braslaus".


Actually you can do a sqrt:

\the\floatexpr\pfsqrt 2\relax

\scratchdimen\floatexpr\pfsqrt 2\relax
\the\scratchdimen

[NTG-context] new units

[Hans Hagen via ntg-context]

Hi,

We now officially have three new units. These were officially introducd 
at the 2023 BachoTeX meeting in a presentation where the chair of the 
four person strong team also did the final live callibration (using the 
edithorial callibration instrument made for that purpose). An upcoming 
article in TB will explain the details of the process and also a careful 
mathematical annalysis of how we reached the right value with a high 
precission. The actual implementation is the most boring part.


\starttext

\startTEXpage[offset=1ts]
Hello World!

\the\dimexpr 1ts

\the\dimexpr 1es

\the\dimexpr 1eu

\eufactor20

\the\dimexpr 1eu
\stopTEXpage

\stoptext

The es (Edith) unit replaces the inch, and the ts (Tove) is one tenths 
of than (just like we have cm and mm). The eu (European Unit) is an 
adaptive one that defaults to 10 ts == 1es and can be multiplied by 
setting the \eufactor (default 10) which makes it possible to define 
layouts that easilly scale to different output media (important for the 
mobile phone / table generation).


This means that MWE that use inches will likely no longer be considered 
valid and probably will be dealt with slower (or just ignored).


These units can be used in the current upload. In a next upload the "19 
feet max" message that tex issues when reaching a maximum will be 
adapted to a more realistic variant. (Actually, because tex has no foot 
unit, we could as well replace that with a more impressive little feet 
unit but we forgot to measure the smallest foot present which i guess 
was about 3 es so the limit is then some 75 bare theodores.)

Dear list,

In case someone else stumbles upon this issue, the following code works.

MWE:

\autofences

\starttext

$\left]-\infty; a\right[$

\stoptext

Re: [NTG-context] New c-o-w: The XMas gift for ConTeXt users

[Zdeněk Svoboda via ntg-context]

Hello Willi,

I'm glad that it "sorted itself out". I will look into the bugs with 
Chrome later but it is weird indeed. I was developing the app mostly 
using Firefox, so it should work fine there hopefully.


Thanks for the progress animation, but I will have to take it out 
because I believe it is under copyright so there will be just a boring 
spinning circle.


Sincerely,
Zdeněk

Hello Zdeněk,

in addition to the former mail I would like to tell you, that I tested now also 
with Firefox (108.01). — Login went fine, logout went fine, the files I 
uploaded/created are shown in the fil-pane and the letter-eating bug did not 
occur with the test-file. — It looks like there is something also related to 
Chrome…

I would like to congratulate you also for the “progress” animation, cute!

Kind regards
Willi

Hi Willi,

Strange bug being thrown out of the editor while not logged in -- I'll have to 
look into that because I have not encountered it yet.

May I ask what browser and OS are you using? I'm unable to reproduce the bug 
with the tab-key in tabulate.

I know about the letter-eating bug and apparently I haven't been successful in 
fixing it yet.

As for the files lost:
   1. you created an account,
   2. uploaded some files and pictures,
   3. then tried to generate a PDF which got stuck,
   4. so you refreshed the page,
   5. and the files were lost?
Am I correct? I will try to reproduce it taking your steps and will try to fix 
it.

And for the logout -- you did not manage to logout at all?


Thank you for the kind words. I'm hoping it will be a useful tool to promote 
ConTeXt!

Hello Huang,

This was probably an error on my side.

Can you please try again now? I have tried to fix it, it should 
hopefully work now.


Sincerely,
Zdeněk Svoboda

Dne 28. 12. 22 v 3:01 黄复雄 via ntg-context napsal(a):

You can probably test with uploading a font the the work directory.


Hans,
thanks for the tip.

I uploaded a noto-cjk font file, NotoSerifCJKsc-Regular.otf, to the
root directory.
Also, my typography file, test.tex, is in the root directory, and it reads

```context
\definefont[myfont][file:NotoSerifCJKsc-Regular.otf*default at 12pt]

\starttext

{\myfont 我我}

\stoptext
```

Then I did not get the correct PDF file, i.e. the two Chinese
characters are not displayed on it. and the log shows:

```log
..
fonts > defining > forced type 'otf' of 'NotoSerifCJKsc-Regular' not found

..
```

I  processed on my Win10 PC, with the same font file, test.tex and the
same directory structure,
and got the correct PDF file and the log is as follows:

```log
..

I am working on a MacBook Air, 10 year old, updated to the latest possible Os 
version, which is Big Sur (11.7), in this case I used Google Chrome.

You are correct. I created a file with the provided interface and saved it 
several times while building the test. During the building I uploaded two 
pictures, which were present in the file-pane. After this experimenting with 
the letter-eating bug the engine got in a endless loop which I had to terminate 
by closing the browser. After reopening the web-site the three files were gone.

> And for the logout -- you did not manage to logout at all?

I was not at all able to logout.
Is it the normal behaviour of this site, that you are automatically logged in 
again when starting?

Again thank you for your work. I am also impressed about the overall 
performance of the tool!

Can you configure your editor to inject 4 spaces instead of a tab

In the meantime I also created an account. — Strange that I have to confirm the

confirmation is asked for.


it avoids ghost users so a one time thing


Not withstanding all my comments, I am impressed how your system works. Once it

Re: [NTG-context] New c-o-w: The XMas gift for ConTeXt users

[Zdeněk Svoboda via ntg-context]

Hi Willi,

Thank you for the feedback!

Strange bug being thrown out of the editor while not logged in -- I'll 
have to look into that because I have not encountered it yet.


May I ask what browser and OS are you using? I'm unable to reproduce the 
bug with the tab-key in tabulate.


I know about the letter-eating bug and apparently I haven't been 
successful in fixing it yet.


As for the files lost:
  1. you created an account,
  2. uploaded some files and pictures,
  3. then tried to generate a PDF which got stuck,
  4. so you refreshed the page,
  5. and the files were lost?
Am I correct? I will try to reproduce it taking your steps and will try 
to fix it.


And for the logout -- you did not manage to logout at all?


Thank you for the kind words. I'm hoping it will be a useful tool to 
promote ConTeXt!



Sincerely,
Zdeněk Svoboda

Re: [NTG-context] New c-o-w: The XMas gift for ConTeXt users

[Willi Egger via ntg-context]

Hi Zdeněk!

Congratulation, the online version, the web-site looks very nice. you have 
built in a lot of nice features!

I tried the interface for a short while. During testing I was thrown out each 
time and you do not understand why. — Does this have to do with the fact that I 
did not create a user-account?

While creating a tabulate I detected, that the use of the tab-key is only 
possible at the beginning of the line. When using the tab-key inside a tabulate 
line the whole line is indented for another tab.

While it is nice to see all the available command-choices it is rather less 
intuitive, that always the brackets are placed. Specially while editing \bTABLE 
… \eTABLE and the commands belonging to this table-type it could be good to 
have the right arrow key to have the command placed with brackets and with the 
down-arrow-key the command being placed without brackets (?) — I think, that 
the source should not be cluttered with empty brackets all over the place.

When you start the editor from the website you have no idea, what the layout of 
the page will be. While being somewhere in the edited text I switched to the 
layout-wizzard. Strange enough it is A4 on A3-Paper, I think for a normal user 
it should be A4 on A4 paper. The default layout dimension is in pt. — I doubt 
whether this is the best for a newcomer. May be mm would be better? — After 
returning to the editor I detected, that the new layout is placed at the 
cursor's position. Might it be a good idea, to place this at the top of the 
document or probably to ask the user whether the layout change should be placed 
at the cursor’s place?

In the meantime I also created an account. — Strange that I have to confirm the 
account to an e-mail, which does not make any reference to what account this 
confirmation is asked for.

Nice is that now I was not kicked out of the editor anymore!

While testing further I experienced, that the system is eating up a letter: 
\blank[small] —> caused a sequence undefined error: in the log there was 
\blank[smal … Hereafter I put a space after small  and it worked correctly. 
Then I withdrew the space, saved the file and started generation of PDF. — got 
a hanger… After restarting everything it appeared, that my test file was not 
listed in the editor’s left pane and also not the two uploaded picture-files. — 
I tried to logout. Logout does not seem to work.

Not withstanding all my comments, I am impressed how your system works. Once it 
will be stable I am convinced, that it can be a useful tool to promote the use 
of ConTeXt. Thank you for all the work performed so far!

Kind regards

Willi

[NTG-context] new upload

[Hans Hagen via ntg-context]

Hi,

I uploaded lmtx. There have been some additions to tabulate.

\starttext

This permits top and bottom alignments of text blobs without interrow 
spacing being disturbed.


A bit more weird addition is the new \TM (move) option:

\starttext

\defineorientation[test][orientation=down,vertical=top]

\stoptabulate
\stopbuffer

\stoptext

This uses some new low level alignment options that operate on rows as a 
whole. As usual, I have no clue what users will come up with but the 
idea is that these 'moves' are independent of the alignment so the in 
this case shifted columns actually keeps their alignment. (It is mostly 
about consistent support luametatex engine features but it might come in 
handy.)


Some other 'new' things are too obscure to mention now,

It's a matter of choice. It's not so much about 'support'because these 
fonts work ok, but more about what is a reasonable subset of fonts for 
cjk (covering all of chinese, japanese, korean).


You can probably test with uploading a font the the work directory.

Hi Zdeněk,

your site is pretty impressive. Congratulations for your awesome work!

It surely will help users, especially the ones new to ConTeXt.

[NTG-context] New c-o-w: The XMas gift for ConTeXt users

[Zdeněk Svoboda via ntg-context]

Hello ConTeXt community!

I'm Zdeněk Svoboda, a master degree student at Mendel university in 
Brno. I've been using ConTeXt for a while now and have always been 
impressed by its capabilities and the helpfulness of this community.


For my thesis project with Tomáš Hála as the supervisor, I've developed 
an online application for working with ConTeXt. The main goal was to 
create an application capable of compiling ConTeXt source right from the 
browser but I thought that it's not enough and added a few features or 
tools on top of that. Functions of the application include:


    - User accounts to save files and access them from other computers.
    - Editor with syntax highlighting and autocompletion for ConTeXt 
command.

    - Generating PDF document and previewing it directly from the browser.
    - Layout designer to customize the layout of their documents with a 
variety of options and mouse resizability of each layout element.
    - Table designer for creating and customize tables with alignment 
and border settings, colors, merging and splitting cells eg.

    - Lists designer with a simple interface to customize lists.
    - Help function for ConTeXt commands (hidden under the "?" button)

Developing this application was a great learning experience for me, and 
I faced a number of technical challenges along the way. For example,

Hi Hans,

many thanks for the new upload.

Now it is updated fine in my rather weird Windows system (at work).

Many thanks for the new version again,

[NTG-context] new upload

[Hans Hagen via ntg-context]

Hi,

I uploaded a new version. New is that we can apply hz to math, although 
currently we have configured it as experiment.


\setupbodyfont[pagella]

% \startluacode
% fonts.expansions.vectors.math = {
% [0x002B] = { 4, 0 }, -- +
% [0x2212] = { 4, 0 }, -- -
% [0x003C] = { 8, 0 }, -- <
% [0x003D] = { 8, 0 }, -- =
% [0x003E] = { 8, 0 }, -- >
% [0x002F] = { 2, 0 }, -- /
% [0x0028] = { 2, 0 }, -- (
% [0x0029] = { 2, 0 }, -- )
% [0x005B] = { 2, 0 }, -- [
% [0x005D] = { 2, 0 }, -- ]
% }
% \stopluacode

\setupmathematics[hz=yes]

\startbuffer \showglyphs
\dorecurse{20}{\strut test $x + y/2 - w = 10$ }\unskip
\stopbuffer

\definecolor[tgreen][g=1,t=.5,a=1]
\definecolor[tred]  [r=1,t=.5,a=1]

\startTEXpage[offset=5dk]
\startoverlay
  {\ruledvbox to 5cm{\setupalign 
[tolerant,stretch]\tgreen\getbuffer\vss}}
  {\ruledvbox to 
5cm{\setupalign[hz,tolerant,stretch]\tred\getbuffer\vss}}

\stopoverlay
\stopTEXpage

\stoptext

Normally an expansion factor is small and used for both stretch and 
shrink, but we can have them independendent. So, here we stretch rather 
extreme but don't shrink.


\setupmathematics[hz=yes]

only kicks in when we have hz enabled as alignment option. We can of 
course configure more 'stretchable symbols' but first we want to know if 
it makes sense at all. We can also imagine to disable it in specific cases.

Denis,

Thanks for the feedback.

No, you are not missing anything. The ConTeXt command list comes from a
file that Hans & Hraban maintain - to create the PDF version of the ConTeXt
commands guide that is available with the distribution -
https://wiki.contextgarden.net/Documentation (we convert that file into a
Typescript object and then use it in the Language Server).

Yes, this is an obvious improvement point that you have highlighted - I
will work with Hans & Hraban to improve it.

Best,

Hello All,

I have published the new VSCode Extension for ConTeXt, that I presented during

You can install it manually in the VSCode (using the "Install from VSIX..."

This supports ConTeXt markup and for any Lua code (within \startluacode &

Many thanks for your reply, Hans.

A complete install has revealed the real cause of the slow download: the
antivirus software (that works like crap).

The time that I thought it was downloading each single file, it was
really analyzing it.

Even worse, when the AV software didn’t like the contents of the file,
it saved an empty file (I have seen it with text and PDF documents).

I had a backup copy, so it updated it (manually) with what a new install
for Win64 (which I got in Linux64).

curl is installed in both Linux and Windows (and there was no secure
install on any of them).

And according to lines 634-640 from mtx-install.lua, if curl isn’t
installed, the installation script should quit:

  if environment.argument("secure") then
usecurl = checkcurl()
if not usecurl then
  report("no curl installed, quitting")
  os.exit()
end
  end

Or what am I missing here?

Many thanks for your suggestion, since it helped to discover the real
cause of the non-working update.

Hi Hans,

I have tried updating ConTeXt in Windows this morning and I’m afraid it
hasn't worked.

Until I can manage this, I think I will download (to the extend that is
possible [and if this works at all]) a Win64 distribution using Linux64
with "--platform=win64".

The problem is clearly not the speed of the internet connection. I use
internet with the standard speed.

There are two things that strike me as possible causes.

1. Depending of which update is pending, the script announces a
different number of files to be downloaded.

The problem is that each individual file download seems to require a
complete connection.

I mean, it takes about ten seconds to establish a connection for each
file. It is irrelevant how big the file actually is.

After that, it isn’t much harder to download the LMTX binary than a tiny
text file.


so then just do a complete install


For most files, they aren’t downloaded in the first connection (they may
require more than three downloads). It doesn’t seem to depend on size.

This is what makes it hard to reach even 10% in the download.

And even if some files may have been downloaded, once the script quits,
the already downloaded files need to be downloaded again (since the main
download process wasn’t completed).

2. The whole download is http instead of https.


sure, but if you have the curl(lib) installed in principle one could do 
a secure install (I didn't really test it but it's in there)



Sorry, but this may be causing the delay in the connections (because
they may be being filtered by the company proxy [and I don’t want to ask]).

https://lmtx.pragma-ade.nl seems to be the only source used (in Windows)
and its certificate is only valid for lmtx.pragma-ade.com (according to
Firefox).


hm, you can change the url in the install script (maybe i can set up the 
server differently but not now)



Even using "./install.sh --secure --platform=win64" (I’m on Linux now,
no Windows here), I get:

mtx-install | instance : install-lmtx
mtx-install | platform : windows
mtx-install | system   : unix
mtx-install | fetching
'http://lmtx.pragma-ade.com/install-lmtx//texmf.zip'
  […]
mtx-install | fetching
'http://lmtx.pragma-ade.com/install-lmtx//texmf-context.zip'

I don’t know whether this is a bug or it is intended.

BTW, "local function checkurl()" on line 52 of mtx-install.lua ends with:

   and find(s,"rotocols")


not important (p P)


I think it might read (although this doesn’t seem to change anything in
my case):

   and find(s,"protocols")

Is there anything that I could to to improve the download process?
If per-file is slow at you end you can try to just install the whole lot 
(just delete the tex tree or at least the tma file that stores the 
hashes) because then the zip is downloaded and installed (one fetch).

Hi Hans,

I have tried updating ConTeXt in Windows this morning and I’m afraid it
hasn't worked.

Until I can manage this, I think I will download (to the extend that is
possible [and if this works at all]) a Win64 distribution using Linux64
with "--platform=win64".

The problem is clearly not the speed of the internet connection. I use
internet with the standard speed.

There are two things that strike me as possible causes.

1. Depending of which update is pending, the script announces a
different number of files to be downloaded.

The problem is that each individual file download seems to require a
complete connection.

I mean, it takes about ten seconds to establish a connection for each
file. It is irrelevant how big the file actually is.

After that, it isn’t much harder to download the LMTX binary than a tiny
text file.

For most files, they aren’t downloaded in the first connection (they may
require more than three downloads). It doesn’t seem to depend on size.

This is what makes it hard to reach even 10% in the download.

And even if some files may have been downloaded, once the script quits,
the already downloaded files need to be downloaded again (since the main
download process wasn’t completed).

2. The whole download is http instead of https.

Sorry, but this may be causing the delay in the connections (because
they may be being filtered by the company proxy [and I don’t want to ask]).

https://lmtx.pragma-ade.nl seems to be the only source used (in Windows)
and its certificate is only valid for lmtx.pragma-ade.com (according to
Firefox).

Even using "./install.sh --secure --platform=win64" (I’m on Linux now,
no Windows here), I get:

mtx-install | instance : install-lmtx
mtx-install | platform : windows
mtx-install | system   : unix
mtx-install | fetching
'http://lmtx.pragma-ade.com/install-lmtx//texmf.zip'
 […]
mtx-install | fetching
'http://lmtx.pragma-ade.com/install-lmtx//texmf-context.zip'

I don’t know whether this is a bug or it is intended.

BTW, "local function checkurl()" on line 52 of mtx-install.lua ends with:

  and find(s,"rotocols")

I think it might read (although this doesn’t seem to change anything in
my case):

  and find(s,"protocols")

Is there anything that I could to to improve the download process?

Many thanks for your help,

Pablo

the math goodie files (work in progress, we will clean them up later) as

Something is wrong with the placement of limits around an integral with 
NeoEuler:

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]

\starttext
\startTEXpage[offset=1mm]
   $\displaystyle \int_{0}^{1} f(x) dx$
\stopTEXpage
\stoptext

gives the attached result.


This is because the integral "sits wrong" in its boundingbox. Almost
all fonts have the glyph centered around the math axis, but there are
a few that doesn't. In euler-math.lfg, add the tweak

{
tweak = "fixoldschool",
},


This fixes the issue with eulernova, but not with pagellaovereuler. 
pagellaovereuler uses euler-with-pagella-math as a goodie file, but that is 
missing from the distribution. (I simply copied euler-math.lfg for my use case).

With tweak=fixoldschool, \startcases doesn't work correctly (see attached):

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8,

\setupbodyfont[mainfont,10pt]

\starttext
\startTEXpage[offset=1mm]
   \startformula
 \startcases
   \NC A \NC B \NR
   \NC C \NC D \NR
 \stopcases
   \stopformula
\stopTEXpage
\stoptext


Looks like some older experimental value is wrong:

   parameters = {
-- DelimiterPercent=  901,
DelimiterShortfall  =  500,
},

(that whole lfg is a todo)

I think there is some free upgrade policy. In general the old font

(ance it's done there will be an article about the improvemnets that 
clarifies things).


We already concluded long ago that the suite of math fonts is somewhat

good as possible and believe that we have found the right mixed 
approach. If needed we can catch averythign in the goodie files but we 
try to minimize it so once this is all settled down, we can improve 
specific font related issues based on {\em realistic} user mwe's as we go.


Concerning large operators .. it worked before so ... the main reason 
why in e.g. euler it failed was a configuration option (euler fonts will 
be fixed too) which is a side effect of more advanced script anchoring 
in lmtx.



The issue I observed with the new upload of 2022.10.15 is that the 
presentations I typeset with the simpleslides module are broken after three 
pages, but could not set up a minimal working example to send to the list. 
Those presentations are typeset correctly with previous versions.
Has Metapost changed some crucial settings ?
some mp->tex interfacing macros were upgraded but that should not really

not affect single sided documents)

In Lucida the integrals have almost been at the right place. See the
attached screenshot. To the left, the unfixed Lucida (first aligned at
the base line, and then centered around the math axis). To the right,
the same with fixed Lucida.

In the eulernova example that Aditya shows, the difference is much
bigger. The fixoldschool tweak fixes it, but it is of course better if
it gets fixed in the font.

Regarding the Lucida fonts: When you bought them you should have got
some login information. That should still work, and you should be able
to upgrade your fonts when released. I don't know how they (TUG) do
releases, though, if they send out information to all people who
bought the font. Hans and I are only involved in the fixing.

/Mikael

PS There are some other glyphs in Lucida that will be fixed. The <, >,
\oiint and \oiiint (displayed versions of the integrals). If you add
them (and, say also a = close to the < and >) to a document, and use
\showglyphs you will see why.

This fixes the issue with eulernova, but not with pagellaovereuler. 
pagellaovereuler uses euler-with-pagella-math as a goodie file, but that is 
missing from the distribution. (I simply copied euler-math.lfg for my use 
case). 

With tweak=fixoldschool, \startcases doesn't work correctly (see attached):

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8, 
features=none]
\setupbodyfont[mainfont,10pt]

\starttext
\startTEXpage[offset=1mm]
  \startformula
\startcases
  \NC A \NC B \NR
  \NC C \NC D \NR

This is because the integral "sits wrong" in its boundingbox. Almost
all fonts have the glyph centered around the math axis, but there are
a few that doesn't. In euler-math.lfg, add the tweak

{
tweak = "fixoldschool",
},

In fact, we have not updated the euler goodie file for a while it
seems. I think there are more things that can be improved. Hopefully
before next release.

It can also be mentioned that some fonts (Daniel Flipo was quick to
fix concrete, erewhon and kpfonts) was fixed recently regarding this,
and it is reported on and fixed in development of Lucida.

Something is wrong with the placement of limits around an integral with 
NeoEuler:

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8, 
features=none]
\setupbodyfont[mainfont,10pt]

\starttext
\startTEXpage[offset=1mm]
  $\displaystyle \int_{0}^{1} f(x) dx$
\stopTEXpage
\stoptext

gives the attached result.

Aditya

Many thanks for the new version, Hans.

I have discovered that it includes in
tex/texmf-context/source/luametatex what should be the LMTX source
(about 11MB).


It zips to 2 MB and totals to less of a picture on a fancy phone ...


Many thanks for your reply, Hans.

At least on my system, I think every file is downloaded uncompressed.

With a low speed connection (here, the service isn’t great all the
time), having to download over 400 files is a killer.


as has been pointed out, you only download the changed files and those 
are not many


when sources are not included some complain, when they are others 
com-plain ...



The storage space on disk is irrelevant, I totally agree with you.

I wish I could say that large updates such as these weren’t a problem in
some cases. But sometimes this isn’t true here.

With incremental updates, the downloading process takes way shorter in
subsequent updates (as Alan pointed out). But the first time it might
take too much (so the script quits).


just run twice as the script will pick up


the idea is to provide the user with all he needs as archive so no
dependencies (apart from a compiler). Also by including the source we
can sort of guaranteed that you get what you expect to work with the tex
files (no interference with distribution patches our of our control). It
has always been part of the plan with luametatex. So ... it will not be
optional.


I asked to make this optional not to avoid having the source, but to be
able to complete the update process.


i guess a few extra fonts are more demanding, actually the number of 
fonts in the installation dropped (for now) so that compensates the 
larger source tree



I’m not extremely confident, but I hope I will manage to update ConTeXt
at the office (next working day).

Many thanks for your reply, Hans.

At least on my system, I think every file is downloaded uncompressed.

With a low speed connection (here, the service isn’t great all the
time), having to download over 400 files is a killer.

The storage space on disk is irrelevant, I totally agree with you.

I wish I could say that large updates such as these weren’t a problem in
some cases. But sometimes this isn’t true here.

With incremental updates, the downloading process takes way shorter in
subsequent updates (as Alan pointed out). But the first time it might
take too much (so the script quits).

I asked to make this optional not to avoid having the source, but to be
able to complete the update process.

I’m not extremely confident, but I hope I will manage to update ConTeXt
at the office (next working day).

Many thanks for your help,

Pablo

Many thanks for the new version, Hans.

I have discovered that it includes in
tex/texmf-context/source/luametatex what should be the LMTX source
(about 11MB).
It zips to 2 MB and totals to less of a picture on a fancy phone .. tre

Subsequent installs should only download source files that have been
changed, so the download should be faster (also for the font files :-)

I applaud the inclusion, by default, of the luametatex source files.

Thank you everyone who has contributed to this.

Many thanks for the new version, Hans.

I have discovered that it includes in
tex/texmf-context/source/luametatex what should be the LMTX source
(about 11MB).

I wonder whether this could be made optional. Internet speed is not
constant where I live and it was impossible for me to update at work
(after many attempts to download the newer version).

Just in case it would be possible, modules (also as an option) would be
more useful for many of us.

Many thanks for your excellet work,

Pablo

Argh, how could I have forgotten about that. Yes, that makes complete
sense.

Ok good, that's what I was expecting. I've unfortunately used some
programs that even fairly recently depended on the system code page, so
I'm always a little cautious.

Glad that you've figured it out.

Yes, Hans confirmed that that is correct.

Also, you should probably check to make sure that the results of the

buffer from ConTeXt with the following contents:

АБВГДЕЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдежзийклмнопрстуфхцчшщъыьэюя

First, run "chcp 65001" before running "context" and record the size of the
file written. Then, run "chcp 1251" and run "context" again. Hopefully the
file size doesn't change; but if it does, then that means that the binary
content of any file written will depend on the system's default code page,
which would complicate making reproducible hashes.


For more than two decades, all my TeX sources are written in UTF-8.

I thought that ConTeXt would output the same character encoding as in
the source file when saving a buffer.

I haven’t found this issue and I’d say that all my saved buffers are
UTF-8 encoded.

the magic is in

savedata(name,replacenewlines(content),"\n",option == v_append)

because tex reads in and then lost what it saw (cr lf crlf) we use the 
line endings of the operating system (good old typewriters and windows 
use cr+lf and old macs uses cr while linux uses lf)
