Re: [NTG-context] installer

[Otared Kavian via ntg-context]

Hi Alex,

You are right ! I have an alias for the mtxrun in the 
/context-osx-arm64/tex/texmf-osx-64/bin/
folder, but the alias is in an old bashrc file, while I was issuing the command 
in zsh…

Thanks for the help !

Best regards: Otared

Hi Pablo, Hans, Wolfgang,

Indeed, thanks to you I see that in ConTeXt there exist plenty of solutions for

[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}}.
\stopformula

Indeed you are right. However, Hans said the feature would be added in the next 
update: so you have to wait a little bit :-)

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 !

Best regards : Otared

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.

Best regards: Otared

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 
the filename has no suffix.

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.

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.

[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

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.

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.

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

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

[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]

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] fatal error in LMTX

Hi Pablo,

Your example works fine on my machine (MacOS 11.6.4) with LMTX version 
2022.04.11. However in your example the \stopfrontmatter is missing.

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.

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.

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

\stoptext

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},

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

[Otared Kavian via ntg-context]

Hi Hans and Aditya,

Thanks for the clarification. Since for some documents I still use mkiv, I 
ended up using a definition which depends on whether one is using mkiv or lmtx, 
as in the example below. I wonder if there is a better solution.

[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:

[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.

[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

\stoptext

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…).

Re: [NTG-context] new upload

[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

\stoptext

Best regards: Otared

[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

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

[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.

Re: [NTG-context] Metapost Animation of Sine

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

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

% begin wave-sine.tex
\usemodule[animation]
\setupinteraction[state=start]
\starttext

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

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

[Otared Kavian]

Hi Mikael,

Thank you so much for the explanation: I am ashamed for not having read this in 
the MetaPost manual.

Just to make sure whether I am beginning to understand, in your example code

> z3 = whatever[z1,z2] = z0+whatever*dir(angle(z1-z0)+90));

should the second « whatever » be 

z0 + whatever*dir(angle(z2 - z1) + 90)) ;

or am I proving that I have not yet understood this wonderful command ?

Thanks again and best regards: Otared

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

[Otared Kavian]

Hi Aditya,

Thanks for the detailed file you sent to answer Dalyoung’s question and file. 
And going through both files I have a question.
I see that both of you use a function « whatever » (but is it a function ?): 
what does this do and where can it be used (actually I have seen Hans using 
this expression, but I had always thought this is just a name…

Re: [NTG-context] Functionnames disappearing (sometimes)

Hi,

I don’t know whether the issue reported by Mikael S. is related to the 
following: since last week (I guess) some math sympbols are not shown either, 
such as \bigcap and \bigcup, even using version 2021.06.18 23:37. An example is:

\starttext
$A \cup B = X \cap Y$
\startformula
A \bigcup B = X \bigcap Y
\stopformula
\stoptext

Re: [NTG-context] mathfun

[Otared Kavian]

Hi Hans,

Thanks for the new features you have introduced in the module mathfun.
Actually I have been using commands such as the one mentioned by Aditya,
\ctxlua{myfunction(args)}
but for the formatting of the output, that is when one wants only 3 or four 
decimal digits, that approach is not very handy.
So I will use the new feature and I’ll put it on the wiki once I have a few 
interesting examples.
By the way, what does 

\complexexpr{123 + new(456,789)}

mean?

Best regards: Otared

After updating to LMTX version 2021.05.15 22:45 the following does not show any

\starttext
Let $f(x) := \sin(x)$.
\stoptext

Please, can someone confirm this behavior ?

Re: [NTG-context] Synctex broken in LMTX ?

[Otared Kavian]

Hi Hans and Nicola,

Thank you for your attention and your answers.

As a matter of fact I am aware that when using ConTeXt with TeXShop one has to 
add on the first line

% !TEX useOldSyncParser

and then setup synctex with

\setupsynctex[state=start,method=min]

(or method=max, or just ignoring that part). In the test file I sent this 
morning, I left out that « % !TEX useOldSyncParser » line, but on my machine, 
with or without it the situation does not change.

In fact a few years ago I was in touch with Richard Koch about the issue and we 
exchanged a few emails and testings, after which he added a Special Comment 
menu item for « % !TEX useOldSyncParser ». 
The ConTeXt code for synctex used to work fine, but beginning last year (if I 
remember well) the behaviour became somewhat unstable (again on my machine). It 
seems that the content which goes on the first page of the PDF file remains out 
of synctex when the file is typeset with LMTX. The same TeX file produces the 
correct synctex result when typeset with mkiv from TeXLive 2020 (version 
2020.03.10 14:44).

Indeed, one can compare the « filename.synctex » files obtained with LMTX and 
mkiv, to observe the differences, but I am unable to interpret why those 
differences are there. 
I am sending those files as well as the TeX and PDF files with this message. 
The PDF file I am sending is the one obtained with LMTX, and of course the 
syncing works fine when one uses the synctex file obtained with mkiv (upon 
renaming adequately that file)…

Best regards: Otared

[NTG-context] Synctex broken in LMTX ?

[Otared Kavian]

Hi Hans,

I have been noticing for some time that \setupsynctex does not work properly, 
at least in TeXShop on MacOS. 
A « filename.synctex » file is created but on most occasions it does not 
contain many lines, and one cannot go from the PDF file to the right location 
in the source file.
Has something changed in the way synctex used to work ?

Below I am sending you a test file with its PDF and .synctex files, for you to 
see for yourself. Sorry for the disturbance…

Best regards: Otared

Re: [NTG-context] \prime is too high

[Otared Kavian]

Hi Jairo,

Indeed \prime seems a littl ebit too high, but using the apostrophe sign for 
derivation gives the expected result:


\starttext
$s''$ or $s’$ is fine but not $s^{\prime}$.
\stoptext

(Using LMTX version 2021.05.09 17:14).

Best regards: Otared

Hi Massi,

Thank you and Hans for this nice feature: is it going to be included in the

Re: [NTG-context] arm osx

[Otared Kavian]

Hi,

Thank you Mojca and Hans for the new binary for MacOS ARM: yesterday I 
installed it on my new MacBook Pro ARM and everything works like a charm.

Just for the persons who run into difficulties when running
sh install.sh
and see that MacOS 11 prevents mtxrun to run properly, in the Finder you should 
find the file

context-osx-arm64/bin/mtxrun

and then you press Control while clicking on it. You’ll see a pop up window, 
and you choose Open, and when the Finder tells you whether you really want to 
open that file, you say YES…
After this, the install script does what it has to do and you don’t need 
anymore to authorize mtxrun to run.

Best regards: Otared

Re: [NTG-context] lmtx update / teaser

[Otared Kavian]

Hi Hans,

Thank you for the new upload.

The teaser examples work fine, many thanks !
I have a question though: how can one center within a page a text, for example 
typeset in a circular shape? I tried with \startalignment, and also with 
\startplacefigure but none of these gives a centered circular shape.

Also I noticed that if one removes the comment at the end of 
\startshapedparagraph, or add a blank line after that, then the circular shape 
is destroyed: is this on purpose ?

Best regards: Otared

% begin example-circular-shape.tex
\starttext

%\startuseMPgraphic{circle}
%   lmt_parshape [
%   path   = fullcircle scaled 136mm,
%   offset = 2mm,
%   bottomskip = - 1.5LineHeight,
%   ] ;
%\stopuseMPgraphic

\startuseMPgraphic{circleBis}
lmt_parshape [
path   = fullcircle scaled 90mm,
offset = 2mm,
bottomskip = - 1.5LineHeight,
] ;
\stopuseMPgraphic

\startalignment[middle]
%\startplacefigure[align=middle,number=no]
\start

Re: [NTG-context] \blackrule and margin

[Otared Kavian]

Hi Uschi,

You may add \dontleavehmode at the right place as in the following:

\setuppapersize[A8,landscape]
\setuplayout[leftmargin=2.5cm,
 leftmargindistance=0.2cm,
 backspace=2.9cm,
 width=4cm]
\showframe
\starttext
\margintext{\hairline\\{Me}}\dontleavehmode\hairline
\startformula
a^n + b^n = c^n.
\stopformula
\stoptext

Re: [NTG-context] metafun

[Otared Kavian]

Hi Hans,

Thanks for the new upload.

For your information, I would like to report that the metafun.tex file typesets 
almost corretly (actually I often typeset it for testing a new upload…) but I 
get a PDF with 400 pages instead the 448 you are mentionning…
The issues are typically some figures not showing up (for instance figures 13.1 
upto 13.13 in chapter 13).

If you think this may be useful for you, I can send you off list the PDF I get 
on MacOS 10.14.6 and today's release of LMTX.

Best regards: Otared

Re: [NTG-context] \showmathcharacters, mk ii, how can I get the list, is not working!!

[Otared Kavian]

Hi Uschi,

Maybe you need to get all math commands which result in a special character: in 
this case you may use the following, and uncomment other commands below to see 
what they give you.

\usemodule[s-math-coverage]
% \setupbodyfont[lucidaot] % Put here the font you are going to use

\starttext

% \showmathalphabets  \page
% \showmathcharacters \page
% \showmathscripts\page
% \showmathbold   \page

\showmathentities   \page

\stoptext

Re: [NTG-context] composing commands

[Otared Kavian]

Hi Hans,

Thanks for the new composing commands. I made several tests and everything 
works great.
I guess when you say something like

> \withgrave   {a} == \\`{a}

you mean

\withgrave   {a} == \`{a}

(this is what I tested…).
Regarding the characters æ and œ, the command \chr produces them correctly, 
that is

\chr{ae} \chr{AE}
\chr{oe} \chr{OE}

produce

æ Æ
œ Œ

as expected.
If you think these commands are to stay, please tell me if they have to be on 
the wiki.

Best regards: Otared

Re: [NTG-context] composing commands

[Otared Kavian]

Hi Hans,

I agree that nowadays most composed characters can be input directly from the 
keyboard (at least judging from my experience with MacOS), but nevertheless it 
may happen that one uses an old file used as an input source file (for instance 
extracting a math exercise from a database) in which there are old fashion 
composed characters. It would be hard to go back and replace those characters 
in each file.
Besides, with the traditional plain TeX composed characters something like

\"c

would give a correct result (the character c with a kind of umlaut on top of 
it), but this cannot be input from the keyboard (and maybe it does not exist at 
all in UTF…). (Actually I just tried \"c with LMTX and mkiv and it does not 
give what is expected from TeX… I am sure it did work some years ago :-) )

If, as you suggest, such composed characters maybe used at the cost of saying 
at the beginning of one's file:
\usemodule[oldschool]
then there is no real harm in removing composing commands, although I am not an 
enthusiastic supporter of removing them.

Best regards: Otared K.

Re: [NTG-context] LMTX isn't typesetting math correctly with Pagella

Hi Jack,I tested your example both with Pagella and Lucida OT: indeed typesetting with the latest LMTX, with Pagella the math italic « f » runs into the right bar of « |f| ».However the result with mkiv is correct.I am attaching the PDF output with LMTX.Best regards: Otared

Hi Jairo,

One can indeed make quizzes and exams with randomized order of problems, 
randomized values and even randomized names of functions and variables.
I have some examples which I have been using for several years (they are useful

Re: [NTG-context] dutch calendars 3 months

[Otared Kavian]

Best wishes for the new year !

Talking of calendars, this one is even more compact: each year is shown on one 
page, and when changing the year only the three lines where the months are 
shown will change:

Re: [NTG-context] Math align not working

Hi Johann,

The example you sent works fine here with LMTX version 2020.12.28 01:41.
Which version of ConTeXt are you using ?

[NTG-context] Metafun: dotlabel issue in latest LMTX

[Otared Kavian]

Hi Hans,

The following (due to you and Aditya, discussed a few days ago) used to work 
with LMTX until version 2020-12-10, but it does not work anymore with LMTX 
version 2020-12-24 17:30. I wonder whether this is due to some changes you have 
made recently.

%% begin squaredot-test.tex
\startMPdefinitions
newpath mydotlabelshape ;
mydotlabelshape := fullcircle ;
mydotlabeldiam := 12 pt ;

vardef mydotlabel@#(expr s,z) text t_ =
label@#(s,z) t_ ;
fill (mydotlabelshape scaled 2mydotlabeldiam) shifted z t_;
enddef ;
\stopMPdefinitions

\starttext
\startMPcode
newpath p ; 
p := (2cm, 3cm) -- (3cm, 5cm);

mydotlabeldiam := 15pt;
mydotlabelshape := fullsquare ;

draw p ;

mydotlabel(textext("\switchtobodyfont[8pt]" & "A"), point 0 of p) 
withcolor transparent("exclusion",.5,red) ;
mydotlabel(textext("\switchtobodyfont[8pt]" & "B"), point 1 of p) 
withcolor transparent("exclusion",.5,red) ;

\stopMPcode
\stoptext
%% end squaredot-test.tex

I get an error message, which is obscure to me, saying:

%-- begin error message excerpt

metafun > log > error: Isolated expression

[NTG-context] freedotlabel not defined in LMTX ?

[Otared Kavian]

Hi Hans,

When I was testing your example with freelabel in another thread, I noticed 
that freedotlabel does not work in LMTX.
Here is the code from the Metafun manual which works with ConTeXt version 
2020.06.25 10:55 MKIV, but not with ConTeXt version 2020.12.24 17:30 LMTX.

%% begin freedotlabel.tex
\setupbodyfont[pagella]

\starttext

\startMPcode
pair destination ;
for whereto = "up", "down", "left", "right" :
destination := scantokens(whereto) * 1cm ;
freedotlabel(whereto, destination, origin) ;
drawarrow origin -- destination
withpen pencircle scaled .25mm withcolor .625 red ;
endfor ;
\stopMPcode

\stoptext
%% end freedotlabel.tex

Hi Garulfo,

Thank you for sharing your nice example: it typesets correctly with mkiv, but

Re: [NTG-context] Problem with \Caps

[Otared Kavian]

Hi Joaquín,

Actually it depends on the font you are using, but on th eother hand it seems 
that \Caps is broken in LMTX.
The following gives a correct result in mkiv but results in an error in LMTX:

\setupbodyfont[lucidaot] 

\starttext

Test {\sc Test} {\Caps Test}

{\smallcaps Test}

\meaning\Caps

\stoptext

Re: [NTG-context] Title in enumeration not working?

[Otared Kavian]

Hi Mikael,

Indeed you are right about the fact that 

> \startexample[title={Title}]
> ...
> \stopexample

is more logical and also more convenient. 
Sorry for not having checked your example in mkiv, where this structure works 
as intended.
So it might be a small buglet in LMTX.

Re: [NTG-context] Title in enumeration not working?

[Otared Kavian]

Hi Mickael,

Maybe this is what you want:

\defineenumeration[example]
[text=Example,
title=yes,
titleleft=,
titleright={.},
]

\starttext
\startexample{Title} 
This is a test.
\stopexample
\stoptext

Of course is you say
text=,
then you get only « Title » and a number in front of it.

Best regards: OK

Re: [NTG-context] upload / metafun

[Otared Kavian]

Hi Hans,

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

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

Best regards: Otared
