[NTG-context] Re: upload

[Otared Kavian]

Hi Hans and Mikael,Thanks for the new module math-goodriddance ! Indeed there are many mathematicians who are going to use the \goodriddancemath command, and no doubt they are going to thank you, even if they are very shy to come out.Moreover this command can be used by people who want to transform the output PDF into an audio file, because for instance the following \usemodule[math-goodriddance]\goodriddancemath\starttext\startformula\int_{0}^{\pi} \sin(x)\dd x = 2.\stopformula\stoptextgives 
		
	
	
		
			
integral from 0 to 휋 , of sin of 푥 d 푥 equals 2 

			
		as one can see in the attached output which is very useful for the blind using an audio software.Best regards: OK

Dear Emmanuel,

Thank you for your reply: indeed I understand your approach, which is quite 
efficient. I am not at all good in coding, so I naively thought there would be 
a way for your setup to retrieve the information it needs from what the user is 
doing. Maybe once things are settled, Hans and Wolfgang will have a look in the 
Japanese part of ConTeXt so that the user can avoid to enter the setup included 
in the \directlua part.

Again thank you for what you are sharing.

[NTG-context] Re: How can I do this?

[Otared Kavian]

Hi Hans and Hraban,

Thank you both for your remarks: indeed I am aware of the commands \m{} and 
\dm{} in ConTeXt, but for my work with math stuff I use the usual dollar signs 
for inline maths, since in this way it is easier for me to read the source on 
the one hand, and and on the hand when exchanging parts of a file with people 
using Plain TeX or LaTeX, it is more standard.

Best regards: Otared

[NTG-context] Re: Japanese

[Otared Kavian]

Dear Dalyoung,

Thank you very much for your insight. I downloaded the Noto Serif JP fonts and 
set up a fontfamily as you indicated, by adding
\setscript[nihongo]
which solves a problem I had with line breakings. And everything works smoothly!

So, for the mail archive, here is what I have and what works fine:

%%% Noto Fonts

\definefontfamily[JapaneseFont][rm][Noto Serif JP]
  [   it={style:regular,features:{*,slanted}},
  sl={style:regular,features:{*,slanted}},
  bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[JapaneseFont][ss][Noto Serif JP]
  [   it={style:regular,features:{*,slanted}},
  sl={style:regular,features:{*,slanted}},
  bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[JapaneseFont][tt][Noto Serif JP]
  [   it={style:regular,features:{*,slanted}},
  sl={style:regular,features:{*,slanted}},
  bi={style:bold,features:{*,slanted}},force=yes]

\definefontfamily[JapaneseFont][math][Tex Gyre Termes Math]
%\definefontfamily[JapaneseFont][math][Tex Gyre Pagella Math]
%\definefontfamily[JapaneseFont][math][Tex Gyre Aventor]



\setupbodyfont[JapaneseFont,12pt]
\setupruby[location=top,voffset=-2ex]
\setupwhitespace[big]
\setscript[nihongo]

\starttext
\ruby{早}{はや}く。
いきましょう。
\stoptext

Actually I followed the example by Emanuel Han which is essentially what you

[NTG-context] Re: Japanese

[Otared Kavian]

Hi Emanuel,

Thanks for the example. In fact I don’t need vertical typesetting for my 
Japanese text, so your example works fine for me. 
Actually I had to change the name of the font to  Hiragino Mincho ProN W3 in 
order to get your example work.

Also I think with the recent versions of ConTeXt there is no need to add 
\enableregime[utf]
because ConTeXt is working with Unicode any way.
I added also a line to define a math font, since I have read here on the 
mailing list that a math font should be set… Maybe someone among the experts 
can tell us if I am right, or if one has to set other fonts as well.

So your example which works fine for me is now:

% begin simple-japanese.tex
\definefontfamily [JapaneseFont] [rm] [Hiragino Mincho ProN W3]
\definefontfamily [JapaneseFont] [ss] [Hiragino Mincho ProN W3]
\definefontfamily [JapaneseFont] [mm] [math] [lucidaot] [default]

\setupbodyfont[JapaneseFont,14pt]
\setupruby[location=top,voffset=-1.6ex]
\setupwhitespace[big]

\starttext  

\ruby{僕}{ぼく}はもう\ruby{寝}{ね}る。

お\ruby{休}{やす}みなさい＾＿＾

\stoptext
%end simple-japanese.tex

[NTG-context] Japanese

[Otared Kavian]

Hi all,

Does anyone have a simple setup of fonts to write a small Japanese document 
(possibly with furagana) ? I am using MacOS and I have several Japanese fonts 
on the system.
I have some old examples which do not typeset correctly now, maybe because they 
use the old module simplefonts and  commands such as \setcjkmainfont and 
friends.

Many thanks in advance: Otared

[NTG-context] Re: Square right aligned

[Otared Kavian]

Hi Ursula,

I think you mean the so-called end of the proof sign, or QED (Quod Erat 
Demonstrandum). You can use this:

\definesymbol[QED][\mathematics{\square}]
\def\qed{\wordright{\symbol[QED]}}
\starttext
This is the end of our proof. \qed
\stoptext

In principle it is included in ConTeXt, but it seems that in the latest version 
I have (2024.01.23), the command \qed is broken.

Best regards: Otared

[NTG-context] Re: upload

[Otared Kavian]

Hi Thomas,

Thank you for your advice: I did add
chmod +x install.sh
and now the script runs without MacOS complaining. 

However, since I had downloaded a new script yesterday and had updated to 
version 2024.01.23, I cannot check whether the issue was adding +x to the file 
install.sh.

Best regards: Otared

Hi again,

I ended up downloading a new version of install.sh for MacOS from the Pragma

[NTG-context] Re: upload

[Otared Kavian]

Hi Dr Hans Van der Meer,

Thank you for your help. It seems that since January 18 something has changed 
(either on MacOS or on the install script), because the last time I could 
update without doing anything more than sh install.sh.

In any case I checked xattr with
which xattr
and got:
/usr/bin/xattr

Then I did 
xattr -d com.apple.quarantine /Applications/context-osx-arm64/install.sh
and got:
xattr: /Applications/context-osx-arm64/install.sh: No such xattr: 
com.apple.quarantine

Invoking again sh install.sh resulted in the error message I reported 
previously.

Best regards: Otared

[NTG-context] Re: upload

[Otared Kavian]

Hi Hans,

I tried to update to your latest version (for MacOS Arm1) with the command 
sh install.sh
but obtained the following message and no update:

xattr: bin/mtxrun: No such xattr: com.apple.quarantine
install.sh: line 110: 62611 Killed: 9   $PWD/bin/mtxrun --script 
./bin/mtx-install.lua --update --server="$LMTXSERVER" 
--instance="$LMTXINSTANCE" --platform="$PLATFORM" --erase 
--extras="$LMTXEXTRAS" $@


Since I have a working (and backed up…) version 2024-01-18, there is no 
absolute necessity for me to update right now, but I wanted just to inform you 
about the issue I encountered. I wonder whether other MacOS users have had such 
a problem.

Best regards: Otared

Hi Pablo,

Indeed the two URL you mention result t a 404 error. I guess the correct URL is
 https://www.pragma-ade.nl <https://www.pragma-ade.nl/>

and there one may go to the appropriate tab.

[NTG-context] Re: upload

[Otared Kavian]

Dear Dalyoung, dear Mikael,

I installed anew the whole LMTX tree and now everything is working fine. 
I don’t know whether this is related or not, somehow in my previous tree I had 
a directory (or folder in the MacOS language) named « texmf-osx-64 » instead « 
texmf-osx-arm64 » and this apparently had consequences.

In any case everything works fine now.

Thanks to Hans, Mikael and all the people on this list!

Best regards: Otared

Hi Hans,Thanks for the new upload which solves the math alignment mechanism.

[NTG-context] Re: How to obtain older versions of LMTX?

[Otared Kavian]

Hi Gavin,

Thanks for the information: since I mostly use the stand alone ConTeXt, I have 
not looked into my TeX Live tree recently. 
Now I’ll do it, but Hans released a new version of LMTX which fixes the issue I 
was reporting.

Thanks again for your help.

Hi Gavin,

Thanks for your reply. Does TeX Live contain LuaMetaTeX (LMTX)?
That is because I need LMTX to typeset a presentation for which most of the 
content is ready, but using features from LMTX…

[NTG-context] How to obtain older versions of LMTX?

[Otared Kavian]

Hi all,

In order to circumvent a bug in the latest versions (2023-09-26 and 2024-01-08) 
of LMTX regarding math alignments, I am trying to get an older version of LMTX 
(from before September 2023) for MacOS ARM. Does any one know how to proceed?

Thanks in advance.

Hi Mikael,

Thank you so much for your attention and help.
Is there a way to get a working version before Hans does a new upload? Or even 
a temporary patch?
This is because I have to prepare a presentation for next Monday and I have to 
use extensively math align…

[Otared Kavian]

Hi Hraban,

Thank you for your updating of the modules stuff.
As far as I remember the matrix features are not related to any modules, but 
rather are part of LMTX. In nay case next week I will look at the page 

https://wiki.contextgarden.net/Matrix_in_maths 
<https://wiki.contextgarden.net/Matrix_in_maths>

and verify that eveything on that page works fine and is up to date.

[NTG-context] Re: Question about building an array of values with Lua

[Otared Kavian]

Hi Fabrice,

As Wolfgang points out, it is indeed possible to fill-in your table with Lua: 
maybe you were wondering how to fill the columns 2, 3 and 4. In this case you 
need to use the Lua function math.mod as in the following, which is a completed 
version of what Wolfgang sent:

%% begin filling-with-lua.tex
\starttext

\startluacode
context.startxtable{ align = "middle,lohi", bodyfont = "9pt", framecolor = 
"black" }
context.startxrow{ background = "color", backgroundcolor = "lightgray" }
context.startxcell{ nx = 4 }
context("Units digit of")
context.stopxcell()
context.stopxrow()
context.startxrow()
context.startxcell{ width = "1cm" }
context.im("a")
context.stopxcell()
context.startxcell{ width = "1cm" }
context.im("a^2")
context.stopxcell()
context.startxcell{ width = "1cm" }
context.im("b")
context.stopxcell()
context.startxcell{ width = "1cm" }
context.im("2b^2")
context.stopxcell()
context.stopxrow()
for i = 0,9 do
context.startxrow()
for j = 1,4 do
context.startxcell()
if j == 1 then
context(i)
elseif j == 2 then
context(math.mod(i*i,10))
  elseif j == 3 then
context(i)
  else
context(math.mod(2*i*i,10))
end
context.stopxcell()
end
context.stopxrow()
end
context.stopxtable()
\stopluacode

\stoptext
%% end filling-with-lua.tex

Re: [NTG-context] Protect the lettrine

[Otared Kavian via ntg-context]

Hi,

Adding \hfill\break to the short line solves the issue, but probably there is a 
better way to achieve the correct result.

\setupinitial[n=2]

\setuphead[chapter][
  after={\placeinitial},
  page=no,
]

\starttext
\chapter{one}
Kermit Ruffins \hfill\break % <---

Meet me at the second line.

\chapter{two}
\input knuth

Meet me at the second line.
\stoptext

Hi Alex,

You are right ! I have an alias for the mtxrun in the

Re: [NTG-context] installer

Hi Hans,

Updating to current version: 2023.05.07 16:33 and issuing

mtxrun --script install-modules

I get:

mtxrun  | unknown script 'install-modules.lua' or

[NTG-context] Did dotless i disappear ?

[Otared Kavian via ntg-context]

Hi Hans,

I just noticed that the dotless i « \i » is not anymore recognized in ConTeXt. 
Of course one can nowadays find other ways to have it typeset, but in old 
documents which are included as inputs one has to correct this manually (for 
instance in French « connaître » was typed as « conn\^{\i}tre »).

Here is an example.

\starttext
Bío Bío (works fine…)

B\'{\i}o B\'{\i}o % this gives an error

\stoptext

[NTG-context] Bug in maths environment: thematrix

[Otared Kavian via ntg-context]

Hi Hans,

I noticed that in some situations the command \thematrix does not show all its 
arguments correctly: some parts are omitted in the typeset formula. In some 
occasions adding some groupings solves the issue, but not always. I noticed 
this bug two weeks ago, but could not produce a minimal example until now…

Please see below, in particular the output for the matrices M_1, M_2 and M_3…

Best regards: Otared

% begin bug-thematrix.tex
\starttext
\startformula
M_{1}(t)
:= \thematrix{{\rm e}^s ; {\rm e}^t}, \qquad
B_{1}(t) := \thematrix{1 , {\rm e}^t},
\stopformula

\startformula
M_{2}(t)
:= \thematrix{{{\rm e}^s} , {{\rm e}^t}}, \qquad
B_{2}(t) := \thematrix{0 ; {{\rm e}^t}},
\stopformula


\startformula
M_{3}(t)
= \thematrix{{\rm e}^s, {\rm e}^t ; 0 , {\rm e}^t}.
\stopformula


\startformula
M_{4}(t)
= \thematrix{1, {{\rm e}^t} + 1 ; 0 , {{\rm e}^t}}.

Indeed you are right. However, Hans said the feature would be added in the next

Re: [NTG-context] update

[Otared Kavian via ntg-context]

Hi Hans,

Thank you very much for the new update.

Everything seem to work like a charm. In particular I played with the 
\underbrace and \overbrace when adding something under the \underbrace, or 
above the \overbrace, like in 

\startformula
\overbrace{1+x^2+a}^{= -1} +
\underbrace{ax^2 + bx + c}_{=2} = 1
\stopformula

and it works great !

Re: [NTG-context] autospacing and colonequals (was Lucida-1.901 (2023-01-21) available)

[Otared Kavian via ntg-context]

Hi Hans and Mikael,

Thank you both for your attention to my reply and the clarification and hints 
regarding the comman \colonequals and 
\setupmathematics[autospacing=yes]

Indeed the command \colonequals give the precise expected alignment for the 
combination glyph « := ». Befors changing the combination « := » to 
\columnequals in my documents, I am wondering whether one could add a small lua 
code in order to make an automatic replacement at run time. Actually, since I 
don’t know of any other instance in which the combination « := » is used to 
mean something else, would it not be reasonnable to make « := » synonym to 
\colonequals?

I played a little bit with 
\setupmathematics[autospacing=yes]
and it seems to me that without this command one gets automatic spacing in math 
mode, while with the above command the spacing obeys what has been inserted in 
the source. Is this behaviour intended, or is there a mismatch between 
\setupmathematics[autospacing=yes]
and
\setupmathematics[autospacing=no]

Best regards: Otared

Re: [NTG-context] Lucida-1.901 (2023-01-21) available

[Otared Kavian via ntg-context]

Hi,

Thanks Hraban for the information and the link to the article by Hans and 
Mikael about the math fonts in Lucida.

I very much appreciated that article: one sees how the handling of almost 
impercebtile details in ConTeXt make us to adhere to and love LuaMetaTeX… So a 
great thank you to Hans and Mikael for all this work!

Regarding the details of vertical alignment in math, I wonder whether the 
column « : » in front of the equal sign « = », in the combination « := » (used 
to define for instance a new variable) should be alos centered around the math 
axis, as explained in the article. For instance in the following example

\setupbodyfont[lucidaot,12pt]
\starttext
\startformula
f(x) := -(u|x) := - \langle u, x \rangle
\stopformula
\stopformula
\startformula
f : A \longrightarrow B
\stopformula
\stoptext

it seems to me that the lower dot (or square…) in the semicolumn of the first 
formula (in front of the equal sign) is lower than in the second formula.

Re: [NTG-context] \typefile not including file and returning success

[Otared Kavian via ntg-context]

Hi Marco,

If I create a file named « bar.txt » then

\starttext
Nothing to say\dots

\typefile{bar.txt}

\stoptext

gives the correct result. However ConTeXt seems to dislike \typefile{bar} when

Re: [NTG-context] Mathematical MetaFun Mania

[Otared Kavian via ntg-context]

Hi Hans,

Thanks for the new release and the nice anchoring features.

I played a little bit with these, and noticed some issues: in the following 
example, linking the bottom bounds of the integral signs is fine (as long as 
numbers are put there), but for the upper bounds, the \infty and \pi/2 are not 
accepted (nor is any letter or greek symbol), but if one replaces \infty and 
\pi/2 with numbers, then the link between the upper bounds is shown. (In this 
example the links are invading the text, but probably this is due to the fact 
that I just copied the Metapost snippet you sent to Gavin).

Best regards: Otared

Hi Hans, Mikael,

These features are amazing! Many many thanks!
Thanks also to Gavin for having stated so precisely these kinds of needs, so 
that Hans and Mikael could come up with this solution.
Gavin, good luck with your project, and plaese share what you get at the end.

Re: [NTG-context] Bug in math alignment

[Otared Kavian via ntg-context]

Dear Jeong,

Thanks for testing my example, and pointing to the solution using \dm (which I 
didn’t know…).
I think the correct behaviour of math alignments should avoid using additional 
commands such as \dm.

We’ll see what Hans and Mikael say.

Best regards: OK

[NTG-context] Bug in math alignment

[Otared Kavian via ntg-context]

Hi Hans and Mikael,

I think there is an issue with the size of math fonts in \frac when used in 
math alignments, as it is is shown in the following example.


%% begin bug-mathalignment.tex
\definemathmatrix[alignedcases]
[align={1:right,2:left,3:left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]

\starttext
Consider this
\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC \qquad\text{on 
}\, \partial\Omega. \NR
\stopalignedcases
\stopformula
or this (with\type{\displaystyle} added)
\placeformula 
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \displaystyle\frac{\partial u}{\partial {\bi n}} \NC = V u + \phi \NC 
\qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula
Actually, one should have this
\startformula
\frac{\partial u}{\partial {\bi n}}  = V u + \phi  \qquad\text{on }\, 
\partial\Omega.
\stopformula
If one adds \type{\displaystyle} both to the numerator and denominator of 
\type{\frac}, the result is correct:
\placeformula 
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \frac{\displaystyle\partial u}{\displaystyle\partial {\bi n}} \NC = V u + 
\phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula

\stoptext
%% end bug-mathalignment.tex

Re: [NTG-context] Backgrounds has changed in latest lmtx

Hi Thomas,

Sorry for answering too late… Meanwhile you found the culprit :-)

Anyway, I cleaned the cache, did a rebuild and typeset your example files. They 
do typeset, but as you pointed out the math font is from LMR, not Stix as you 
specified.

Hi Thomas,

Both your examples typeset fine with my installation of LMTX (version

fine also).

Re: [NTG-context] Backgrounds has changed in latest lmtx

[Otared Kavian via ntg-context]

Hi Thomas,

Your example does indeed show the issue I had reported on with Simpleslides: 
the backgrounds of the slides are not as expected.
So it seems that beginning with version 2022-10-15 something has changed with 
Metapost or the background mechanism.

Re: [NTG-context] new upload

[Otared Kavian via ntg-context]

Hi Mikael,

I use Lucida in my documents and did not notice any problem with the integrals 
and other large operators. 
Do you mean in the future I have to update to a new version of Lucida (and pay 
again…) or will future versions of LuaMetaTeX handle correctly large operators 
typeset in Lucida ?

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 ?

Best regards: Otared

Re: [NTG-context] cannot update ConTeXt to 2022.09.16

[Otared Kavian via ntg-context]

Hi Pablo,

I had the same issue and, as this was discussed a few years or months ago, 
after removing the three files with extension « .tma » the update goes through 
normally.
On my machine, running MacOS X, I had to remove the following files:
texmf.tma
texmf-osx-64.tma
texmf-context.tma

Re: [NTG-context] Sudoku module

[Otared Kavian via ntg-context]

Hi Wolfgang,

Thank you for your reply and the explanations about the function « 
interfaces.implement ».

Regarding the examples given by Jairo, you are correct: those examples can be 
typeset with LMTX. I did a mistake when in TeXShop I saved the file « 
t-sudoku.mkvi » under the name « t-sudoku.tex »: indeed this creates an error 
in LMTX as well in earlier versions of ConTeXt… (maybe a colateral consequence 
of the heat wave in France :-)

I apologize to you and Jairo for having caused any trouble.

Best regards: Otared

Re: [NTG-context] Sudoku module

[Otared Kavian via ntg-context]

Hi Wolfgang,

Thank you for your attention and the explanation regarding the « hash option » 
and why the sudoku module written by Jairo does not work. However I was 
reporting the issue when I tried to typeset the example file with LMTX (version 
2022.07.06 21:42). 
As a matter of fact I am far from understanding what the « arguments = { « hash 
» } » is supposed to do in interfaces.implement in the code you sent…

[NTG-context] Sudoku module

[Otared Kavian via ntg-context]

Hi Jairo,

You sent a message last year about your Sudoku module, and today, out of 
curiosity, I wanted to test it. Unfortunately it stops with an error message at 
line 76 of the file t-sudoku.mkiv, where you have:

\def\sudokufunction_direct[#name][#parameters]#content

I would appreciate if you could tell me whether you have a working version of 
you module, or what one has to change in order to typeset your examples.

[NTG-context] Bug in placeformula

[Otared Kavian via ntg-context]

Dear Hans, dear Mikael,

In my experiments with the new math engine, I noticed that there is an issue 
with \placeformula when one sets the location of the numbers on the left: the 
number is one line above the formula. Here is a minimal example:

% begin bug-placeformula-left.tex
\setupformulas[location=left]

\starttext

\placeformula
\startformula
a^2 + b^2 = c^2.
\stopformula

\stoptext
% end bug-placeformula-left.tex

Moreover, in some environments (such as enumerations) the bug destroys 
completely the flow of text but I could not set up a minimal example to send 
you.

Best regards: Otared

Dear Hans and Mikael،

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

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

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

Re: [NTG-context] \sciteinlinebuffer inherits margin properties

Hi Pablo,

The example you gave in your first message about the Scite module, that is:

  \usemodule[scite]

  \startXML ñ\stopXML
  \stoptext

gives an error on my machine (MacOS 11.6.5 and Context version 2022.05.11

I don’t know where the error comes from…

Re: [NTG-context] upload

[Otared Kavian via ntg-context]

Hi Aditya and Mikael,

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

Here is a working example:

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

\starttext

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

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

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

Re: [NTG-context] upload

[Otared Kavian via ntg-context]

Hi Mikael,

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

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

Best regards: Otared

Re: [NTG-context] upload

[Otared Kavian via ntg-context]

Hi Hans,

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

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

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

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

\setupbodyfont[myfont,9pt]

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

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

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

Your test file works fine if I place

However in the file you sent the choice of the command

However there seems to be an inconsistency, as in the example below: in this 
particular example it is better to use explicitely \bi to have bold italic.

\starttext

text {\italicface text {\boldface text} text} text

text {\it text {\bf text} text} text: here the third instance of text is in 
boldface, but not in italic boldface.

text {\it text {\bi text} text} text

Re: [NTG-context] OT world history: other measuring systems?

Regarding the issue of the absolute necessity of defining a standard time the 
book by Peter Galison « Einstein’s Clocks, Poincaré’s Maps » gives some 
interesting insight. In particular, since after the mid 19th century trains 
were developed while the time was not standardized, many accidents happened 
with hundreds of people killed. This led Henri Poincaré, Lorentz and Einstein 
(among other mathematcians and physicists) to th enotion of relativity…

Regarding the measure of the distance, area, volumes and weight indeed each 
region of the world had its own units because the trade and exchange of 
products were essentially local. With the progressive extension of the 
exchanges between regions and countries the need for a standardization appeared 
more and more.
For example the problem of measuring grains is a quite difficult one: if one 
measures the weight, depending on how much humidity the grains contain, one has 
different amount of the real stuff. If one measures the volume of the grains, 
then according how compressed they are, the amount of the grains may be 
different… (at some point there was a law which stated that when a unit vessel 
of grains was to be sold, the seller should struck the bottom of the vessel on 
a table three times and then refill again sthe vessel for it to be full).

The measure of the distances on roads in the Persian empire had one unit and 
one subunit: « parasang » and « mil ». Parasang, which means « big stone » in 
Persian, was the average distance which a fantassin could walk in a certain 
amount of time, and was marked by a large piece of stone on the road (this is 
also reported by Herodotus). Each parasang was divided into three « mil », 
which means « iron bar » in Persian, and was marked by planting an iron bar on 
the road side. A parasang is between 5400 and 6000 meters, and thus a « mil » 
is something about 1800 and 2000 meters. These units were used in many areas 
outside the Persian empire, and are still used, in particular the parasang, in 
Iran and Afghanistan (in Iran a parasang is 6 kilometers now). (Personnaly I 
think the Roman mile has its origin in the Persian « mil »: I think the 
etymology of the word mile based on the word « mille », a thousand, cannot be 
correct since it does not correspond to one thousand of any other unit of 
length used in the Roman empire).

Best regards: Otared

[NTG-context] definemathcommand and Lucida OT

[Otared Kavian via ntg-context]

Hi Hans,

Some time ago I reported about an issue with \definemathcommand, and the issue 
is still present, as one can see with following example.

Best regards: Otared
% begin liminf-Argmin.tex

\setupbodyfont[lucidaot]
%\setupbodyfont[termes]

\definemathcommand [Argmin]  [limop] {\mfunctionlabeltext{ArgMin}}
\definemathcommand [liminfbar]  [limop] {\underline{\mfunctionlabeltext{lim}}}
\definemathcommand [limsupbar]  [limop] {\overline{\mfunctionlabeltext{lim}}}

\starttext
The built-in commands \type{\liminf}, yielding $\liminf$, and \type{\limsup}, 
yielding $\limsup$ do not work properly with LucidaOT:
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminf_{n \geq 0}x_{n} = -1, \quad 
\limsup_{n\geq 0} x_{n}= +1.
\stopformula

The user defined commands \type{\liminfbar} and \type{\limsupbar} behave 
correctly:
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminfbar_{n \geq 0}x_{n} = -1, \quad 
\limsupbar_{n\geq 0}x_{n} = +1,
\stopformula
but not the command \type{\Argmin}
\startformula
\Argmin_{x\in {\Bbb R}} (x^2 - x + 1) = {1 \over 2}.
\stopformula

\stoptext

[NTG-context] Bug in alignment with LMTX version 2022.01.15 17:32

[Otared Kavian via ntg-context]

Hi Hans and Mikael,

While investigating the latest version regarding the math environment, I found 
that the alignments are not correct.
Here is an example:

% begin bug-alignment.tex
\definemathmatrix[alignedcases]
[align={right,left,left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\starttext

\placeformula[eq:1]
\startformula
\startalignedcases
\NC  \partial_{t} u  \NC = \Delta u + \epsilon^{-2}f(u) \NC\qquad\text{in }\, 
\Omega\times (0,+\infty) \NR
\NC {\partial\phi(u) \over \partial{\bi n}} \NC = 0 \NC\qquad\text{on }\,  
\partial \Omega\times (0,+\infty)\NR
\NC u(x,0) \NC = u_{0}(x)\NC\qquad\text{in }\, \Omega.\NR
\stopalignedcases
\stopformula

\stoptext
% end bug-alignment.tex

[NTG-context] Simpleslides and LMTX

[Otared Kavian via ntg-context]

Hi Aditya and Thomas,

Following the hint given by Thomas about fixing the behaviour of the visual 
counter in the simpleslides module, I tried all the possible styles and found 
that once the PageNumber is changed into RealPageNumber in the 
s-simpleslides-*.tex
style files. All the styles work fine unless three of them which I describe 
below.
I don’t know how the modules are maintained on the wiki or elsewhere, but if 
you wish I can send you privately the files where I have changed PageNumber to 
RealPageNumber so that the simpleslides module can be used ot of the box with 
LMTX.

Best regards: Otared
PS: Here are the issues with the three styles which don’t work properly:

• BigNumber: for the style to be typeset,  one has to modify the part where 
BigNumberFont is defined

%\beginOLDTEX
%\loadmapfile[qhv-ec.map]
%\definefontsynonym  [BigNumberFont] [ec-qhvb] 
%\endOLDTEX
%
%\beginXETEX
%\loadmapfile[qhv-ec.map]
%\definefontsynonym  [BigNumberFont] [ec-qhvb] 
%\endXETEX
%
%\beginLUATEX
\definefontsynonym  [BigNumberFont] [name:texgyreherosbold]
%\endLUATEX

Then the file « example.tex » can be typeset, but the big numbers shown are 
always 1.

• Embossed: for the style to be typeset, one has to modify the part where 
EmbossedFont is defined

%\beginOLDTEX
%\loadmapfile[qhv-ec.map]
%\definefontsynonym [Embossed] [ec-qhvb] 
%\endOLDTEX
%
%\beginXETEX
%\loadmapfile[qhv-ec.map]
%\definefontsynonym [Embossed] [ec-qhvb] 
%\endXETEX
%
%\beginLUATEX
\definefontsynonym [Embossed] [name:texgyreherosbold]
%\endLUATEX

• SideToc: the file example.tex can be typeset with this style, but all pages 
come out in black… the text cannot be seen.

Re: [NTG-context] SimpleSlides and Visual counters

[Otared Kavian via ntg-context]

Hi Thomas,

Thanks for your attention. Indeed I could have asked you, but since Aditya 
answered my previous message I continued asking him…

Anyway, you are correct: replacing PageNumber with RealPageNumber everywhere, 
the visual counter is shown correctly…

For the sake of the mail archives, in case someone else encounters the issue, I 
add the example below.

Many thanks for help !

Re: [NTG-context] SimpleSlides and Visual counters

[Otared Kavian via ntg-context]

Hi Aditya,

Some time ago I reported an issue with LMTX regarding your visual counter (at 
least the version used in the simpleslides module).
Now I think I have found where the issue comes from: it is due to the fact that 
somehow the conditional

if PageNumber > 2 :

[some code]

fi ;

is not treated correctly, and if one removes the conditional while keeping only 
[some code] above, then the visual counter is shown correctly. 

I am sending you the TeX file where you can see that if lines 17 and 46 are 
uncommented then the visual counter does not show up.

Thanks for your help: Otared K.

Re: [NTG-context] Why mtxrun fails ?

[Otared Kavian via ntg-context]

Hi Jean-Pierre,

In which directory (or « folder », speaking MacOS…) have you installed the 
ConTeXt tree ? 
For instance, on my machine, I have installed the ConTeXt LMTX tree in

/Applications/context-osx-arm64/

and then if for example I need to execute the mtxrun coming with this tree, I 
can say

/Applications/context-osx-arm64/tex/texmf-osx-64/bin/mtxrun - -generate

(beware the « - - generate » should be actually two successive « - » dashes 
without a space between them… I am using Mail.app on my Mac and it replaces the 
two dashes with a longer n-dash « — »).

Of course the best would be to create an alias for 

/Applications/context-osx-arm64/tex/texmf-osx-64/bin/mtxrun

in your .bashrc, if you use bash.

Best regards: Otared K.

Re: [NTG-context] critical fun

[NTG-context] Math in LMTX and definemathcommand

[Otared Kavian via ntg-context]

Hi Hans,

Thank you for the new upload and the rewriting of the math fonts stuff, thanks 
also to Mikael S. I did several tests on real size math projects and did not 
notice important issues.

The two issues I noticed, show up mainly with LucidaOT, and are explained in 
the following example:

\setupbodyfont[lucidaot]

\definemathstackers[MySymbol]
[voffset=-1.4\mathexheight, % -.8\mathexheight
hoffset=\zeropoint,
mathclass=ord,
topoffset=.3\mathemwidth, % poor man's italic correction
middlecommand=\mathematics]

\define[1]\interior{\mathover[MySymbol]{176}{#1}} %2218 U+00B0

\definemathcommand [Argmin]  [limop] {\mfunctionlabeltext{ArgMin}}
\definemathcommand [liminfbar]  [limop] {\underline{\mfunctionlabeltext{lim}}}
\definemathcommand [limsupbar]  [limop] {\overline{\mfunctionlabeltext{lim}}}

\starttext
If $A \subset {\Bbb R}$ is a set, its interior is denoted by $\interior{A}$. 
Can one have the circle over $A$ slightly bigger (probbaly this is font 
dependent)?

The built-in commands $\liminf$ and $\limsup$ do not work properly with 
LucidaOT (I tried other fonts and there they are fine):
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminf_{n \geq 0}x_{n} = -1, \quad 
\limsup_{n\geq 0} x_{n}= +1.
\stopformula

The commands defined above, \type{\liminfbar} and \type{\limsupbar}, behave 
correctly in all fonts I tested:
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminfbar_{n \geq 0}x_{n} = -1, \quad 
\limsupbar_{n\geq 0}x_{n} = +1,
\stopformula
but not the command \type{\Argmin} (which does not show Argmin in any font…)
\startformula
\Argmin_{x\in {\Bbb R}} (x^2 - x + 1) = {1 \over 2}.
\stopformula

Hi Aditya,

Thank you for your attention and your kind reply.

I am sending a setup file with an example of presentation, which shows the 
issue with LMTX while with mkiv the result is fine.
Actually as you can see in the setup file, I have slightly modified the visula 
counter in order for it to be interactive (clicking in the center of the visula 
counter gives a jump to the previous location…).

[NTG-context] SimpleSlides and Visual counters

[Otared Kavian via ntg-context]

Hi all, in particular Aditya M. and Thomas A.S.,

It seems that the visual counter in  SimpleSlides module (the version I have 
from ConTeXt Garden is from 2014) does not work fine with the latest LMTX.
Is the issue is known ? If so, is there a new version of SimpleSlides in which 
the issue has been fixed ?

Re: [NTG-context] \externafigure and \at do not work together

[Otared Kavian via ntg-context]

Hi,

Your example has two issues, since you invoke \externalfigure before 
\starttext, and moreover you don’t use the place figure mechanism.
The following gives the result you want:

\setupinteraction[state=start]
\starttext
\startplacefigure[reference=clock]
\externalfigure[clock.jpg]
\stopplacefigure
In figure \at[clock] you see a clock
\page
In figure \at[clock] you see a clock. 

Or better: in \in{Figure}[clock] you see a clock.
\stoptext

Best regards: Otared

Sure… But then maybe it is possible to define one’s own « ordinals.french » for 
messy cases :-)

Hi Wolfgang,

Thanks for the example and the fix, but I would rather think that the « french 
» part of ordinals should be

french = function(n)
if n == 1 then
return « er"
else
 return « ème"
end
end,

Now if this were not accepted as a fix in core-con.lua, is there a way for a 
user to change the default to the above choice in his document ?

Hi Bruce,

Thanks for your reply. 
I don’t know what has triggered this change, which seems to me strange and 
inconvenient.

Sure, but I don’t understand why the behaviour has changed. It seems to me a

[NTG-context] Strange new behaviour of the mailing list

[Otared Kavian via ntg-context]

Hi all,

I noticed that beginning July 27th, the messages distributed by the ConTeXt 
mailing list appear to be from

Mailing list for ConTeXt users

without the actual name of the sender appearing. It may be dependent on the 
mail client I am using (Mail.app on MacOS 11.4), but I wonder whether something 
has changed on mailing list server, and whether if there is something I can do 
to have the old behaviour (which was convenient when one wanted to follow up 
mails from some specific contributors). 

Also has anybody else noticed this change?

Thanks in advance for any hint.
Best regards: Otared

Re: [NTG-context] Metapost Animation of Sine

Hi Jeroen,

Unfortunately I am not familiar with Tikz, since all my documents use what is 
built-in ConTeXt and Metapost…
That being said I am sure someone on the list can help you with Tikz module.

Re: [NTG-context] Metapost Animation of Sine

[Otared Kavian]

Hi,

Adding to my previous message, if you are looking for an animation of the wave 
equation for a string with fixed endpoints, one has to use something like the 
following:

% begin wave-sine-string.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=2pt]
\startanimation[menu=yes,framerate=10]
\dorecurse{101}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt, N ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel - 1 ;
N := 500 ; % number of steps
path p ;
p := (0u,0u) for i = 1 upto N : 
-- 
(((mylength/N)*i)*u,cos(omega*(mylength/N)*tt)*sin(omega*(mylength/N)*i)*u) 
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
\stopTEXpage
\stoptext
% end wave-sine-string.tex

Re: [NTG-context] Metapost Animation of Sine

Hi, 

I wonder whether something like the following is what you are looking for:

% begin wave-sine.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext
\startTEXpage[offset=2pt]
\startanimation[menu=yes,framerate=10]
\dorecurse{100}{\expanded
{\startframe
\startMPcode
numeric u, omega, mylength, tt ;
u := 2cm ;
omega := 4 ;
mylength := 3.141596 ;
tt := \recurselevel ;
path p ;
p := (0u,sin(omega*(mylength/100)*tt)*u) for i = 1 upto 
100 : 
.. 
(((mylength/100)*i)*u,sin(omega*(mylength/100)*(i + tt))*u) 
endfor ;
draw p withpen pencircle scaled .5pt withcolor darkred ;
\stopMPcode
\stopframe}
}
\stopanimation
\stopTEXpage
\stoptext
% end wave-sine.tex

[NTG-context] Hyphens broken with lucidaot

[Otared Kavian]

Hi Hans,

I noticed that with the recent LMTX version 2021.06.27 16:59 the hyphens do not 
show up correctly with lucidaot.
Here is a minimal example and the resulting PDF

\setupbodyfont[lucidaot,10pt]
\startTEXpage
c'est-à-dire

sous-ensemble

sous-préfet
\stopTEXpage

Best regards: Otared

Re: [NTG-context] simplifying repeated macro calls in metafun

[Otared Kavian]

Dear Dalyoung, dear Mikael

Thank you both for your explanations: indeed this « whatever » command in 
MetaPost is magic and very useful (I am not sure whether it is a command only 
in MetaFun, or it exists also in the original MetaPost).

Regarding the way Aditya uses \startuseMPgraphic, it is also very instructive. 
Dalyoung, can you also share the animation example for the foldings ? I am sure 
we are a few on the list to learn something…

Best regards: Otared
