[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

/Applications/TeX/context-osx-64/tex/texmf-osx-64/bin/context (which was built

/bin/bash: line 4:  1579 Abort trap: 6   context TestCode.tex
===

Trying to install again, I get:


sh install.sh

./bin/mtx-install.lua --update --server="$LMTXSERVER" 
--instance="$LMTXINSTANCE" --platform="$PLATFORM" --erase --extras="$LMTXEXTRAS"

What can I do?

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

Desperately,

Ralf

[NTG-context] new upload

[Hans Hagen]

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

This permits top and bottom alignments of text blobs without interrow

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,

Hans

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,

Pablo

[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.

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:

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:

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).

mentioned here (or known to those who wanted it) the main changes are in
the math goodie files (work in progress, we will clean them up later) as
part of improving the rendering of math.


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.


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, 
features=none]
\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 
should work ok given that one can live with the (current) inaccuracies 
(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 
inconsistent (between and within fonts). We try to deal with that as 
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 
matter much so i need an example of what goes wrong (quite some month 
ago we fixed some left/right page related interfacing but that should 
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
\stopcases
  \stopformula
\stopTEXpage
\stoptext

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.

Thanks,
Aditya

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,

Hi Hans,

I too can confirm that this seems to be a bug with the latest upload 
[current version: 2022.04.20 19:18]. This was last working with the 2022.04.15 
version. In the logs I get:
  publications> start used btx commands
  publications> default  textquotesingle  1 unknown
  publications> stop used btx commands

[Meanwhile, I am using the publ-ini file from the previous upload as a 
temporary fix]

Thanks,

Hi Hans,

While the typesetting issue in Metafun disappeared, another popped up in
the bibliography.

For an entry with \usebtxdefinitions[apa], it is printing ": [author:
Robert L. Boylestad] [date-added: 2022-04-15 14:43:59 +0200]
[date-modified: 2022-04-15 14:45:15 +0200] [edition: 13e] [publisher:
Pearson] [title: Introductory Circuit Analysis] [year: 2016]" in the
resulting pdf.

I should add that it seems independent from the btx format.

Hi Hans,

Thanks very much for the upload and the tutorial on 'adaptive'. It seems very
impressive and right away, one application which I could think of in my case
is its use in denoting prosodic elements in verses (of poems). For this
purpose I was using \definebar, \setupbar so far to indicate certain types of

if you need more control / features it can probably be provided

Dear Hans,

I can use "\blank[9cm]” in column mode but I have to adjust the value to make 
space evenly.
Since it was working well last December, I guess that there is something 
changed in \startcolumns … \stopcolumns after last December.

Thank you.

Re: [NTG-context] new upload

[Jeong Dal via ntg-context]

Dear Hans,

A new upload solves the math font problem in MetaFun. The code
label(textext("$\sin\theta$”),origin);
is working well.
Also, your sample file adaptive-001.tex is also working without error which is 
not compiled before.
However, \vfill is not working in column mode while it provides the same 
vertical spaces properly not in column mode. 
The following code is compiled well but no vertical spaces between items. If I 
comment out \startcolumns … \column … \stopcolumns, it provides the same 
vertical spaces for each items.
\starttext
\startcolumns
\startitemize[n]
\item 
\vfill
\item
\vfill
\column
\item 
\vfill
\item
\vfill
\stopitemize
\stopcolumns
\stoptext

This code was working in last December. 

Thank you for your fix.

Best regards,

Dalyoung

[NTG-context] new upload

Hi,

I uploaded a new lmtx. Some more adaptive magic ... I'm not sure how 
usefull it is but users always find ways to apply such things. I 
attached a test file.

Many thanks for the new upload, Hans.

I’m afraid I get compilation error with your sample:

 lua error:
  callback error: .../base/mkxl/typo-ada.lmt:78:
attempt to call a nil value (upvalue 'traverseleader')
stack traceback:
  .../base/mkxl/typo-ada.lmt:78: in upvalue 'nodes_adaptive_handle'

  .../base/mkxl/typo-bld.lmt:208: in function
<.../base/mkxl/typo-bld.lmt:204>

I got the same error message with a brand new installation.

Just in case it might help,

Pablo

[NTG-context] new upload

[Hans Hagen via ntg-context]

Hi,

I uploaded a new lmtx. Apart from a experimental intersection feature in 
the mp library (and metafun, more will be revealed when MS an I are okay 
with it) there is not that much news.


I decided to turn some test code into a mechanism which is illustrated 
below. Adaptive boxes are hboxes that act a bit like glue which means 
that when we hook in e.g. a graphic it can be made to adapt.


We can add some more methods if needed so maybe you see other usage. The 
interface is rather lightweight and the overhead is quite resonable.


Hans

Next on the todo is to move some experimental graphic trickery related 
to math (matrices) into the core but the interfacing needs some thought.

Wrong.  The imperial measurement system, may give Europeans a headache, but is 
NOT obsolete, by any means.  A good chunk of the world use the imperial 
measurment system and may be required in certain books, depending on a

Hi,

As most of you know by now, Mikael and I are working on a math support 
upgrade. In order to let users keep up we uploaded a new version. We 
have been revisioning some of the more obscure constructs where we have 
  no clue of usage, like pmod, bmod, bordermatrix etc, commands that we

assuming that these are standards.


In this release, encouraged by the positive response we received from

regarding the self-explaining sesac, we have decided to introduced some 
new constructs. First out is

for rotation matrices. This was demanded for some advanced math courses 
that Mikael teaches. It might inspire users to come up with demands that 
suits their own obscure but nevertheless interesting math.


At some point we realized that, with (also) scientific publishers (of 
math journals) moving to MS Word and Indesign, we operate in a rather 
peculiar niche and the fact that we use an upgraded and more granular 
math engine, made us wonder how to communicate all these new features 
and standards that we set. It is for that reason that from now on we 
will operate under the CMS umbrella. That abbreviation stands for 
ConTeXt Math Society. It has no funny swirly TeX logo which itself is a 
statement: in Unicode math script and calligraphic alphabets are so 
messed up that it is impossible to have a reliable and predictable 
rendering. We go for Dutch and Swedish simplicity in the spirit of W.N. 
Lansburgh: back to the times before TeX was written (1964). There will 
be no limits and boundaries set. (Talking math limits and boundaries: 
these can already go everywhere anyway, as can fences.)


So, when we mention CMS, we mean serious math business, but kindergarten 
math is also embraced! There are no consequences for users: ConTeXt 
users with a proven math track record are automatically a member, but we 
are not too picky, everyone is welcome. We don't have honorary members 
but Taco (the first ConTeXt math user) and Aditya (the most experienced 
  one) might consider themselves as such. Mikael Sundqvist is the 
chairman, which is a livelong appointment. (A nice side effect is that 
with Arthur living in Sweden too, that gives us a very strong position 
in the TeX landscape there.)


So, today's upload is sort of special: welcome CMS (ConTeXt Math 
Shines), goodbye AMS (American Math Second). Of course we're open for 
suggestions and it being an open society all voices will be heard, but 
only proper (retro) math cf Lansburgh will be honored. Of course we only 
listen to ConTeXt users and, as that package is not supposed to be used 
for serious math, we don't bother about the few publishers left that 
still do math.


Are we done? Not yet. We're in the middle of (colorful and graphic) 
alignment ornaments and after that we're going to expand and improve 
multi-line display formulas and equation numbering.


It will be no coincidence that the cover of Landburghs book about math

we hope all users are in awe about what the TeX lion can do.

[NTG-context] new upload / more math

Hi,

As most of you know by now, Mikael and I are working on a math support 
upgrade. In order to let users keep up we uploaded a new version. We 
have been revisioning some of the more obscure constructs where we have 
 no clue of usage, like pmod, bmod, bordermatrix etc, commands that we 
 took (and reimplemented) decades ago from plain TeX or AMS TeX, 
assuming that these are standards.


In this release, encouraged by the positive response we received from 
users regarding the new simplealignment construction, and in particular 
regarding the self-explaining sesac, we have decided to introduced some 
new constructs. First out is

for rotation matrices. This was demanded for some advanced math courses 
that Mikael teaches. It might inspire users to come up with demands that 
suits their own obscure but nevertheless interesting math.


At some point we realized that, with (also) scientific publishers (of 
math journals) moving to MS Word and Indesign, we operate in a rather 
peculiar niche and the fact that we use an upgraded and more granular 
math engine, made us wonder how to communicate all these new features 
and standards that we set. It is for that reason that from now on we 
will operate under the CMS umbrella. That abbreviation stands for 
ConTeXt Math Society. It has no funny swirly TeX logo which itself is a 
statement: in Unicode math script and calligraphic alphabets are so 
messed up that it is impossible to have a reliable and predictable 
rendering. We go for Dutch and Swedish simplicity in the spirit of W.N. 
Lansburgh: back to the times before TeX was written (1964). There will 
be no limits and boundaries set. (Talking math limits and boundaries: 
these can already go everywhere anyway, as can fences.)


So, when we mention CMS, we mean serious math business, but kindergarten 
math is also embraced! There are no consequences for users: ConTeXt 
users with a proven math track record are automatically a member, but we 
are not too picky, everyone is welcome. We don't have honorary members 
but Taco (the first ConTeXt math user) and Aditya (the most experienced 
 one) might consider themselves as such. Mikael Sundqvist is the 
chairman, which is a livelong appointment. (A nice side effect is that 
with Arthur living in Sweden too, that gives us a very strong position 
in the TeX landscape there.)


So, today's upload is sort of special: welcome CMS (ConTeXt Math 
Shines), goodbye AMS (American Math Second). Of course we're open for 
suggestions and it being an open society all voices will be heard, but 
only proper (retro) math cf Lansburgh will be honored. Of course we only 
listen to ConTeXt users and, as that package is not supposed to be used 
for serious math, we don't bother about the few publishers left that 
still do math.


Are we done? Not yet. We're in the middle of (colorful and graphic) 
alignment ornaments and after that we're going to expand and improve 
multi-line display formulas and equation numbering.


It will be no coincidence that the cover of Landburghs book about math 
typesetting has a prominent 'AWE' embedded in a logo with a lion on top: 
we hope all users are in awe about what the TeX lion can do.

Ditto - working for me as well.

I completely deleted everything and re-installed using the 64-bit MacOS ARM 
image on this page.


The normal install steps worked: i.e unzip; move the "context-osx-arm64" parent 
directory to where you want it to be (/home/Users//Applications) in my 
case; ran the install script  using the command ". ./install.sh" and it all 
installed nicely. I then added the path it told me about to my .zprofile file 
and to the engine file that I use. Logged out and in just to make sure the 
paths were picked up and it all works from both command line and from TeXShop.

Re: [NTG-context] New upload is DOA on my M1 Mac

Hi List,

ConTeXt is running well after a fresh install. (context version: 2022.03.12 
17:56, I didn’t even need to mess with permissions.) I don’t know why the usual 
update procedure failed for me before. I look forward to checking out the new 
math spacing with Libertinus.

Sorry for the noise, and thanks to everyone who offered me help.

JP and Bruce,

Do either of you have the new upload working on an M1 Mac?

I appreciate the ideas, but I’m not entirely new to this. I’ve kept several 
different ConTeXt installations. I can run them from terminal or TeXShop. I’ve 
written TeXShop engines to switch between different installations and to use 
TeXShop’s alternative path. I’ve never had a problem like the one I am having 
with the new upload.

TeXShop and Terminal both have full disk access. Before I devote much more time 
trying to figure out what might be wrong with my set-up – where other 
installations work fine – I’d love to get confirmation that somebody got the 
new upload to work on an M1 Mac.

Dear Hans,

Thank you for the remarkable upload! Also, thanks Mikael, for your work as well!

The new release coincides with the onset of warm summer months after some cold 
winters where I live ;)

[I am a little late to this discussion since I was held up with some college 
assignments and work, so sorry for that... I just updated today]
I have tested out most of my documents (some with many MetaFun diagrams) and 
all work well!

I have several documents which are very mathematics-heavy and all of those work 
great as well. In fact, I also noticed some improvements especially with 
spacing around fractions and signs/other expressions around them. [I must 
mention that I am using Asana in most documents: it does have its quirks but it 
is what I have; I also use Libertinus sometimes]. Since I have many expressions 
with \left \right braces delimiters with large fractions (fractions of 
fractions, etc.) I was able to notice that the spacing is now better overall. 
Also I see the truth behind the remark in Asana, before the update, many more 
things were strange and I had to manually adjust with spaces as necessary, now 
those don't seem to be necessary. However, Asana continues to remain weird (at 
least with uppercasescript c
haracters as subscripts + delimiters). I had relatively fewer issues with 
Libertinus and no issues with the fonts in LMTX itself. So overall, I am very 
happy with it (and grateful for it).
I also noticed that ontarget document from the previous upload had not much in 
it apart from the attractive cover page. Now it has so many nice details which 
I look forward to studying from.
We're glad that you notice the improvements! So it's worth the effort. 
And more is coming

I think it could be useful, yes (I like the look of the libertinus
font, in particular in combination with the biolinum font; it is
probably worth trying to get the math font to work as well as
possible). I think there were some problems with accents and such, but
not too big. I think you could try to use it and see what you think.

I put it on my todo-list to download the new version and to run some test files.

I could also mention here that in the upload Hans did some days ago,
most changes are "behind the scenes", so the user should not really
write their code differently. One exception:

In integrals, texers have usually a \, in front of the differential.
Now there is a differential class, and the macro \dd will give a
differential d, with (hopefully) correct spacing. Thus, write for
example \int_0^1 f(x)\dd x.

If you find any strange distances between atoms, please mail me
examples. With the introduction of new classes, there are many new
pairs, and perhaps not all of them are setup "correct".

the main issue with math font is in 'unfortunate' glyph dimensions and

Two questions, then:

 1. Is Libertinus Math considered a "useful" math font?

The instance of mtxrun that TeXShop finds is entirely down to path settings 
and/or TexShop preferences settings (in its 'engine' files) and nothing to do 
with the security permissions.

Regarding the security permissions there is something else to check: go to 
System Preferences -> Security & Privacy -> Privacy tab -> Full Disk Access.
Make sure 'TeXShop.app' and 'Terminal.app' are both in the list.

If that still doesn't work then there is one more thing but it will be a PITA. 
:-(

And that is to install Xcode and the Xcode developer tools. This then gives you 
another Privacy entry in the left hand list called "Developer Tools" and, above 
the apps list on the right, the description reads "Allow the apps below to run 
software locally that does not meet the system's security policy." Add 
Terminal.app here.

Hi,

It has been a while since there was an updaste but there it is. The 
most significant 'changes' are:


- more automatic adaption to double sided page properties in metafun 
(lmtx) ... blame sreeram and me for messing up


- more extensibve support for indic fonts which sreeram has documented 
on the wiki (fonts, translutaration etc)


and

- improved math rendering to be documented by by mikael in an upcoming 
manual ... it tooks a couple of months so it is supposed to have some 
impact.


before we move on the the structural compoments and see what can be 
done beter there, we decided to release the first stage that deals with:


= fixing font properties; we don't expect fonts to be improved so 
that's the route we follow


= extensive inter atom spacing (we have many more math classes, some 
in the engine, some in context) and everything can be controlled (the 
old pairwise spacing primitives have been replaced by a more general 
mechanism, including support for fast setup of categories and 
inhertance from other classes)


= idem for inter class penalties, including granular control over line 
breaks using a system of (in/de)creasing penalties


= auto-fenced inline material across lines and linebreaks in molecules 
(read: complex atoms)


= taking stretch and shrink in encapsulated atoms into account in 
linbreaks (using some new box related mechanism that is also available

Hi Gavin!

On MacOSX go to "Finder" and search the app. Then, click the app icon 
while holding down the "Control" key on the keyboard, then choose "Open" 
from the pop-up menu.


Click on "Open". The app is saved as an exception in your security 
settings and you can open it later by double-clicking it, like any saved 
app.


Hope it helps !

I am willing to try. I downloaded the luametatex file at that address, but I’m 
not sure what to do with it. Do I just replace the luametatex in my 
installation, or should I install usining my usual procedure and then replace?

I noticed that problem already before reaching the machine, but I
couldn't quite figure out what was wrong (I was too tired to debug
yesterday evening).

Python apparently keeps throwing some exceptions on the buildbot master.

Maybe I should just compile the binary and upload it manually for now.

[NTG-context] new upload

[Hans Hagen via ntg-context]

Hi,

It has been a while since there was an updaste but there it is. The most 
significant 'changes' are:


- more automatic adaption to double sided page properties in metafun 
(lmtx) ... blame sreeram and me for messing up


- more extensibve support for indic fonts which sreeram has documented 
on the wiki (fonts, translutaration etc)


and

- improved math rendering to be documented by by mikael in an upcoming 
manual ... it tooks a couple of months so it is supposed to have some 
impact.


before we move on the the structural compoments and see what can be done 
beter there, we decided to release the first stage that deals with:


= fixing font properties; we don't expect fonts to be improved so that's 
the route we follow


= extensive inter atom spacing (we have many more math classes, some in 
the engine, some in context) and everything can be controlled (the old 
pairwise spacing primitives have been replaced by a more general 
mechanism, including support for fast setup of categories and inhertance 
from other classes)


= idem for inter class penalties, including granular control over line 
breaks using a system of (in/de)creasing penalties


= auto-fenced inline material across lines and linebreaks in molecules 
(read: complex atoms)


= taking stretch and shrink in encapsulated atoms into account in 
linbreaks (using some new box related mechanism that is also available 
in text and will be explained later)


= spacing at the edges that should not be there but always was there as 
side effect of the engine is now removed; as with other new features 
this can be controlled (we have rulesets for atoms to which we can add 
more in the future)


= more detailed control over (skewed) fractions, (flattened) accents, 
(sized) fences, radicals ... there was already a lot there but it now 
combines with mentioned spacing (when relevant the context macros have 
been adapted to control this which is a bit cleaner)


= we have a new built in muskip (tiny) but as we have an inheritance 
system as well as binding to variables one can set up extensive spacing 
models register and constant binding; the currently set values are based 
on math typesetting references; in the future we might have additional ones


= although we did handle primes already rather transparent in mkiv / 
lmtx, inconsistency in fonts made us decide to make primes first class 
properties of atoms and molecules which means that we now have: pre

The PKGBUILD for luametatex will install the latest _released_ version of LMTX.

I am not picking bins from the build farm. The PKGBUILD downloads the 
context-linux-64.zip from 
http://lmtx.pragma-ade.nl/install-lmtx/context-linux-64.zip, runs install.sh, 
and downloads a few modules from CTAN, installs everything in /opt/luametatex, 
and creates a /opt/luametatex/setuptex script.

BTW, I am not sure which PKGBUILD you mean exactly. Note that there  
are two PKGBUILDs for context on AUR:



1. context-minimal-git:  
https://aur.archlinux.org/packages/context-minimals-git/#news


which installs ConTeXt MkIV

2. luametatex: https://aur.archlinux.org/packages/luametatex/

which installs LuaMetaTeX.

So you probably need to use the luametatex PKGBUILD.

BTW, I am not sure which PKGBUILD you mean exactly. Note that there are two 
PKGBUILDs for context on AUR:


1. context-minimal-git: 
https://aur.archlinux.org/packages/context-minimals-git/#news

which installs ConTeXt MkIV

2. luametatex: https://aur.archlinux.org/packages/luametatex/

which installs LuaMetaTeX. 

So you probably need to use the luametatex PKGBUILD.

The transliteration code is in the next upload but because we're in the 
middle of a massive math class refactoring we fitst need to get that 
right (no problem if something is messed up for a while as it's a matter 
of definitions but at least the engine should behave well).


So ... patience needed,

Yes. Just yesterday while trying to fix some devanagari fonts, I was able to 
get a partial fix to one of the bugs in rendering. Once that work reaches some

  Thank you for this overview.  Do you have a list of the fonts you know

This would be most useful, I think.  I can help collating the

Adishila is a great font too and comes in many more styles (letter press, etc) 
than Shobhika. However the latter has more conjuncts. For example:
ङ्क्ल 
ङ्ग्ध्व
appear as halant forms in Adishila while they are proper conjuncts in 
Shobhika. Of course, these are rare conjuncts, so …

Anyway, in ConTeXt Adishila works well with 
features=devanagari-one

It is very much an ongoing effort. I am working on some proper documentation 
soon to serve as a guide for fonts (what works, what doesn't, fixes, hacks, 
etc). But mostly it is in a very usable state (for the most part).

I am very much a non-expert and helping in very little ways. It is Hans in the 
background who is doing all the really important things with the code, design 
and engineering of the system. So really, we should thank him!

Re: [NTG-context] new upload

[hanneder--- via ntg-context]

(it is a bit of a pity that support for indic scripts is such a  
weird mix of font technology and
engine dependent reshuffling ... probably also driven by limitations  
of open type at that time)>


When using these fonts regularly, one notices very erratic formatting  
phenomena that must have to
do with the Devanagarī font, or its interaction with (Xe)TeX. Perhaps  
this is the same phenomenon

seen from the user side.

In my case things improved when I switched to Adishila (in XeTeX):

\newfontfamily\sanskritfont[Script=Devanagari,Mapping=RomDev,Scale=1.45]{AdishilaSan}

This is, to my taste, the nicest Sanskrit font, but it is difficult to  
decide between Adishila and

Shobhika.

The Murty font is also quite good, but it is commercial and cannot be  
used for book production. I
asked whether there was a way to get a licence, but at the time this  
was impossible. But the font
team there recommended ``Sanskrit Text'' (Sansk.ttf) which is one of  
their products that made it
into a Microsoft Windows Standard font (I am not using Windows). It is  
also very good, but Adishila

works better for me.

I cannot say how thrilled I am about the Indic support, thanks a lot  
to Kaushika!

Shobhika font is a free font that has some of the largest number of glyphs
(i.e has many conjuncts) for the Devanagari script.
https://github.com/Sandhi-IITBombay/Shobhika

The font also has a good Latin component based on PT Serif. This Latin part
has good support for the roman (IAST) transliteration for Sanskrit. But
strictly only the IAST spec character for Sanskrit are available.

It also has glyphs for some commonly used mathematical symbols.

Noto Serif Devanagari is also decent for just Devanagari (not sure  
of the IAST

part).

As for Sans typefaces, Mukta Devanagari is a free font:
https://github.com/EkType/Mukta

Of these, Shobhika has the best conjunct coverage. I will shortly update the
wiki with a much more exhaustive list and report here.

Recently when we were troubled by incorrect rendering of certain
conjuncts in 
malayalam, Hans added a new font-feature. More below*, but first some 
background: from my testing, the main reason for the problems with
fonts seems 
to come from the varied interpretations and/or implementations of OTF 
specification. To add to this complexity there are two script tags
(v1, v2 in 
OTF and -one, -two in ConTeXt) for each writing system (script). While
there 
are fonts which work very well right away many others have issues and
the 
feature was added to somewhat alleviate these issues.

*The feature is 'indic'. It has two aspects: 'movematra' and
'conjuncts'.

conjuncts takes values: mixed | continue | quit | auto
movematra takes values: default | leftbeforebase | auto

By default 
indic=auto 
for indic scripts. So this "should work" in most cases. 

In case there are issues, I have seen that the following approach
usually 
yields best result in debugging:
 • try to switch between the -one and -two version of the features
(i.e. use 
the v1 or v2 OTF script tag): some fonts may have some rules defined
only under 
one of the script tags. (I am not an expert in fonts but with my
testing of 
free fonts I have seen this). 
 • if that does not fix (the particular issue), revert to a working
feature and 
then set the indic feature as indic={movematra=default,conjuncts=quit}
to see
 • Please see:
 https://www.mail-archive.com/ntg-context@ntg.nl/msg99691.html
 issues usually have a pattern (across languages/scripts so some hacks
might 
work)

For conjuncts, 'mixed' and 'auto' are synonymous. Setting
conjuncts=mixed 
ensures that for some fonts conjuncts with the reph forms are rendered
correctly. (This was tested with a relatively new font in malayalam
using the 
mlm2 script tag).

For problematic fonts, if one can identify which conjuncts work under
which 
script tag and/or with what settings for indic, then, using ConTeXt
feature 
sets one can easily fix rendering in documents by doing, for instance
 {\feature[=][devanagari-two] …}, and/or
 {\feature[=][devanagari-one] …} accordingly
 See the comprehensive wiki page: 
 https://wiki.contextgarden.net/Featuresets 
for more details on how such feautresets might be built and applied.

Now, a brief note on the transliterations macros. First, one specifies
that 
indic transliteration is desired with:
\usetransliteration[indic]

Now, one can transliterate sanskrit to and from various forms by using

\transliterate[scheme]{ … }
where scheme is one of:
    • iast to deva
    • deva to iast
    • deva to mlym
which are respectively the following schemes :
    • IAST → Devanagari
    • Devanagari → IAST
    • Devanagari → Malayalam
More schemes will be added in the near future for various other indic
scripts 
as well. Currently there is only support for sanskrit language, which
we can 
extend to other languages (wherever the script allows).

Additionally, there is also 
\definetransliteration[…][…]
which can be used to define a specific transliteration block.

So, one just sets vector accordingly to get the desired
transliteration block. 
Please see below a minimal example for both:

% SOF
\usetransliteration[indic]
\definetransliteration
    [MyIASTtoDeva]
    [color=blue,
 style=bold,
 language=sa,
 vector={iast to deva}]

\starttransliteration[MyIASTtoDeva]%[color=green]   can set a new
color here

Unfortunately some fonts don't work properly in ConTeXt. Noto Sans Devanagari
is one of them. The accompanying serif font (Noto Serif Devanagari) works just
fine (mostly, there are problems with that as well).

In this specific case, there does not seem to be any fix (at least that I could
find).

I am trying to test many fonts and come up with a list of fonts which work,
partially work, don't work, etc. and fixes wherever possible.
Side note: we tested a lot and could find some hacks around font issues 
but in the end decided that adding some heuristics for (maybe whatever 
historic issues) makes no sense because eventually one ends up fighting 
heuristics. So, in the end we removed these fixing features and instead 
just do as announced above: tell what works and not with what fonts (and 
as some fonts are in development we can just wait till things work).


(it is a bit of a pity that support for indic scripts is such a weird 
mix of font technology and engine dependent reshuffling ... probably 
also driven by limitations of open type at that time)

I have myself been using Shobhika with relative success for quite some time 
now. Due to its great conjunct support, it is a good font as well. In ConTeXt 
it is advisable to use it with the deva script tag. So, with 
features=devanagari-one

Please note that it is missing some IAST glyphs
ḻ (=ळ) l̥ ,are just two examples.
[For roman transliteration (IAST), I have seen that the Brill font has very 
good glyph coverage but it does not have vedic accents IIRC.]

However, there is one (minor) issue in the devanagari side of things:
See here (long read): 
https://www.mail-archive.com/ntg-context@ntg.nl/msg99691.html

TLDR: there are one set of conjuncts which don't work right-away, namely the 
र-based conjunct forms with the following consonant: छ, ट, ठ, ड, ढ with post-
base and below-base vowel marks, namely  ी, ा, ौ,  ु  and   ू 
For example छ्री will not render as expected in ConTeXt (with devanagari-one). 
To 
fix this one can temporarily switch to the devanagari-two feature set as 
follows
{\feature[=][devanagari-two] छ्री}
which can be wrapped into a macro.

Otherwise, all the features work well.

Best,
kauśika

Kauśika,

I've been following this thread and the related critical edition
thread
with some interest. I'm wondering, how have you found the new
input/translation method with "Shobhika Regular," a font a few of us
might be keen to use?


Best, Richard

I don't think it's normal (I see the spacing to make room for anything 
that comes after the first character in the exposant, but it is not 
printed).


to get an idea about default and additional spacing in tex ...

\starttext

\startbuffer
\dontleavehmode\ruledhbox{$x^2 + x$}\par
\dontleavehmode\ruledhbox{$x_2 + x$}\par
\dontleavehmode\ruledhbox{$x^^2 + x$}\par
\dontleavehmode\ruledhbox{$x__2 + x$}\blank
\stopbuffer

\startTEXpage[offset=3pt]
\getbuffer
\Umathspaceafterscript \textstyle0pt
\Umathspacebeforescript\textstyle0pt
\getbuffer
\Umathextrasupspace\textstyle20pt
\Umathextrasubspace\textstyle40pt
\Umathextrasupprespace \textstyle10pt
\Umathextrasubprespace \textstyle30pt
\getbuffer
\stopTEXpage

\stoptext

so by default there is space added to scripts (more in latin modern than 
in cmr btw as it is font driven) but one can argue if that makes sense 
at all ... this is why we might default to zero font spacing and 
specific super/subscript spacing instead (just as in lmtx we have 
prescripts and related (fake opentype) spacing)


in a similar fashion there is built-in pre/post fraction spacing that 
makes that we cannot have tight fractions (by default) while in fact 
that has to be driven by proper fraction-class spacing so that's another 
thing that might happen: tight fractions + proper interclass spacing 
(because we have less memory constraints than when tex showed up we can 
add classes without overhead)


(i bet that due to a 'tex does perfect math syndrome' these thinsg go 
unnoticed (not by DEK himself, just look at the chapters on finetunign 
math) ... some of it is also compensate for the width-of-glyph cheating 
that goes on in the traditional engine but that is another matter

if the test suite doesn't crash (i only test that) i'll upload ... it 
has to do with decoupling some in the engine: tex uses lots of shifting, 
cheating on dimensions and displacements that relate to (older) fonts 
and for the purpose of tracing i changed some ... so we're seeing a side 
effect of that


for a while we already have this:

\tracingmath2\tracingonline2

i'll upload a fixed version

fwiw: \frac and friends are currently being redone; for that we now have 
a frac class (as well as rad), so


  \mathfrac{...}
  \mathrad{...}

in addition to \mathord etc other new things are

  \beginmathgroup ... \endmathgroup

that permits better local settings without messing up the spacing due to 
classes and we have dozens more spacing class variables ... all waiting 
to be used (some features are already there for more than a year but now 
get used in low level code, which is why we can expect some instabilities)
