[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

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 ;

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…

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

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)…

[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…

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).

Re: [NTG-context] custom zig zag sidebars

[Otared Kavian]

Hi Massi,

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

Best regards: Otared

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
\startshapedparagraph[list=circle,mp=circleBis,repeat=yes,method=repeat]%
\setupalign[verytolerant,stretch,last]
\dontcomplain

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.

Hi Thomas,

Out of curiosity I tested your MWE and I get 

mtx-context | fatal error: return code: 11

with LMTX (version 2021.01.28 18:22), while with mkiv it typesets correctly.

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

[Otared Kavian]

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

I have some examples which I have been using for several years (they are useful

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

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:

[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

Re: [NTG-context] MetaFun - "remove the paths of text" from a rectangle to let the background visible

[Otared Kavian]

Hi Garulfo,

Thank you for sharing your nice example: it typesets correctly with mkiv, but 
it seems to me that with LMTX the text does not appear (at least on my 
installation of the latest LMTX).

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

Re: [NTG-context] Metafun: is it possible to redefine dotlabel to draw a square ?

[Otared Kavian]

Hi Aditya,
Thank you very much !
That's great indeed, you gave me an elegant solution.
 
One more question, in order for me to understand a little more: when defining a 
new dotlabel as you do, might it not conflict with the internal definitions of 
dotlabel in Metafun in some other place?
Maybe it is safer for me to call it something like  « dotshapelabel » ?

Best regards and agin many thanks: Otared

[NTG-context] Metafun: is it possible to redefine dotlabel to draw a square ?

[Otared Kavian]

Hi all,

In Metafun when representing a point I woul dlike to have some dots represented 
by a square (or even by another scalable symbol): for instance in the following 
I would like the dot at the point B to be a square:

\starttext
\startMPcode
draw (2cm,3cm) -- (3cm,5cm) ;
dotlabel(textext("\switchtobodyfont[8pt]" & "A"), (2cm,3cm)) 
withpen pencircle scaled 12pt 
withcolor transparent("exclusion",.5,red) ;

dotlabel(textext("\switchtobodyfont[8pt]" & "B"), (3cm,5cm)) 
withpen pencircle scaled 12pt 
withcolor transparent("exclusion",.5,red) ;
\stopMPcode
\stoptext

I wonder whether it is possible to define something like « drawsquaredot » or « 
squaredotlabel » in order to do this.
If I use for B the command
withpen pensquare scaled 12pt
then the dot is a square, but the label B is drawn in a strange way.

Thanks for any help: Otared

Thanks Aditya!
One can learn a lot with your answers !
In the Metafun manual I see enlonged but I did not know to use it.

Re: [NTG-context] Metafun: how to draw a straight line past the end points

Hi Aditya,

Thanks for the alternative method, which comes handy if one wishes to extend 
the straight line by a different amount at either end:

\starttext
\startMPcode
   z1 = (1cm,3cm) ;
   z2 = (5cm, 9cm) ;
   z3 = 1cm * dir(angle (z2 - z1)) shifted z2 ;
   z4 = -.5cm*dir(angle(z2 - z1)) shifted z1 ;
   draw z1 -- z3 ; 
   draw z4 -- z1 ;
   draw z1 -- z2 withcolor red ;
\stopMPcode
\stoptext

[NTG-context] Metafun: how to draw a straight line past the end points

[Otared Kavian]

Hi,

I have a silly question: given two points in the plane
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
the command
draw z1 -- z2 withpen pencircle scaled .5pt ;
draws the line segment joining z1 and z2. How could I draw the line segment 
which goes a little further (say 1cm) than both the end points of this segment 
(that is in this example, a point before z1 and a point after z2 on the 
straight line) .
Indeed it is possible to write the equation of the line and then compute by 
hand the coordinates of the new end points, but I think there is a simpler way 
in Metafun to do this.

Thanks for any help: Otared

You may use \text in math formulas as in:

 \item Beneficio por euro: $\frac{\text{beneficios}}{\text{costes}}$.

Re: [NTG-context] Getting the filename which is being typeset

[Otared Kavian]

Hi Wolfgang,

Thank you for your explanations: I am wondering whether this kind of 
information could go into the wiki, and if yes what would be an appropriate 
title for that page (of course I'll do it).

However the two commands 

\inputfilesuffix
\jobfilesuffix

put inside the file « myfile.tex » do not give the suffix « tex »: shoul dthey 
give « tex » or am I misintrepreting these commands?

Best regards: Otared

Re: [NTG-context] Context install for Apple Silicon M1 mac mini

[Otared Kavian]

Hi Keith,

You may try to copy to your new machine the whole folder where you have 
installed LMTX on your old machine, and then run 
context --make
there. Indeed if this works for your current LMTX folder you'll need someone to 
prepare a whole working folder of updated LMTX. As long as I have a PowerBook 
with the old chip (and running MacOS 14), I may do this for you and then put a 
zip file on Dropbox. However I may be too pushed to get a new M1 PowerBook in 
the future.

Best regards: Otared K.

[NTG-context] Getting the filename which is being typeset

[Otared Kavian]

Hi everyone,

I have to typeset a few files which get each an input file named in a certain 
way. For instance, a file named « myfile.tex » in which another file named « 
myfile-buffer.tex » is used as an \input file, as in

% content of myfile.tex
%
\starttext
This is a test.

\input myfile-buffer.tex
\stoptext
%

 When typesetting « myfile.tex » I wonder whether it is possible to get the 
name of the file without its suffix, that is to get « myfile », with a command 
such as
\getNameOfCurrentFile
and then be able to replace the above snippet by:

% desired content of myfile.tex
 %
\starttext
This is a test.

\input \getNameOfCurrentFile-buffer.tex
\stoptext
%

Best regards and thanks for any hint: Otared K.

Hi,
I created a page on the wiki:
https://wiki.contextgarden.net/Matrix_in_maths 

However the LMTX code is not typeset on the wiki. I'll see with taco whether it 
is possible to have lmtx mode on the wiki.

Hi Hans,

Thanks for your insight!
Indeed I'll wikify what you explained, once I have tested it with the next 
upload. Would  \HL and \VL be also available in mkiv ?

Re: [NTG-context] mathmatrix and internal lines

[Otared Kavian]

Hi Jean-Philippe,

A few weeks ago I saw briefly the discussion about Hans' message regarding 
\noalign and the the new definitions of \HR and \VR that you are sending. 
Indeed your solution works great !
Just for the case other people may have the same question about writing block 
matrix, I copy below the whole example which can be found later in the mail 
archive.
(For mkiv, I don't know how to do the same thing…).

%%% begin block-matrix.tex
% in LMTX defining \HR and \VR to create block matrices:
\pushoverloadmode
\noaligned\tolerant\protected\def\HR[#1]{\noalign{\hrule #1}}
\popoverloadmode

\def\VR{\dosingleempty\doVR}
\def\doVR[#1]{\NC \hskip-0.5em \vrule #1 \hskip-0.5em \NC}

\definemathmatrix[mymatrix]
[left={\left(\,},
right={\, \right)}]

\starttext  

\startformula
\startmymatrix
\NC A \VR  B \NR
\HR
\NC C \VR  D \NR
\stopmymatrix
\stopformula

\stoptext
%%% end block-matrix.tex

Hi Jean-Philippe,

The following is better than the one I sent earlier:

\definemathmatrix[mymatrix]
[left={\left(\,},
right={\ \right)}]

\starttext
\startformula
\startmymatrix
\NC A \NC\hskip-.5em \vrule  \NC\hskip-.5em B \NR

Re: [NTG-context] mathmatrix and internal lines

[Otared Kavian]

Hi Jean-Philippe,

For a simple case like the one you sent, a rather not optimal solution can be 
this:

\definemathmatrix[mymatrix]
[left={\left(\,},
right={\ \right)}]

\starttext
\startformula
\startmymatrix
\NC A \hskip .5em |\hskip-.5em  \NC B \NR
\noalign{\hrule}
\NC C \hskip .5em |\hskip-.5em \NC D \NR
\stopmymatrix
\stopformula
\stoptext

However I think I have seen sometime ago a more elegant solution, but I could 
not find it right now…

Best regards: Otared K.

Hi Hans,

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

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

tel que $R > 0$ il existe un entier $n \in {\Bbb N}$ tel que $n\epsilon > R$. 

Plus précisément il existe un unique entier $m \geq 0$ tel que $m\epsilon \leq 
R < (m+1)\epsilon$~: cet entier $m$ est appelé partie entière de $R/\epsilon$ 
et souvent noté $m = \lfloor R/\epsilon \rfloor$ (et l'entier $(m+1)$ est noté

[NTG-context] Fatal error 11

[Otared Kavian]

Hi Hans,

With the latest LMTX (current version: 2020.11.13 19:13), a project (which used 
to typeset correctly until last week) cannot be typeset anymore.
I did try to typeset smaller parts of my files but this did not help:  I keep 
getting

fatal error: return code: 11

and no PDF output. Somewhere in the log I have also

error in line 35, namespace 'mathfences', instance 'curly', key 'curly,'

where in my file \curly is defined as 

\definemathfence[curly][brace][command=yes,factor=auto]

However this command works fine with LMTX when I use it in a minimal example. 
How can I get a more clear error message so that I can localize what the new 
LMTX does not like ?

Of course I can stay with mkiv where my file can be typeset without problem, 
but it would be useful to have error messages which help really the user.

Best regards: Otared K.

Re: [NTG-context] new upload

[Otared Kavian]

Hi Pablo,

I had the same issue as the one you were reporting (on MacOS 10.14.6).
I removed the three files 

texmf-context.tma
texmf-osx-64.tma
texmf.tma

before issuing the command 
sh install.sh

Now I am getting 

fetching 'http://lmtx.pragma-ade.com/install-lmtx//texmf-context.zip

on my Terminal window and I think I will get the new version uploaded by Hans 
(my internet connection is very slow…).

Thank you for the hint…

Best regards: Otared

Re: [NTG-context] cannot update LMTX

[Otared Kavian]

Hi Pablo,

For some unknown reason despite having tried to update lmtx several times, I 
still have version 2020.09.20 23:02.
Indeed I do a backup before any update in order to be able to go back to a 
working version…

What did you do in order to get version 2020.11.04 09:40 ?

Re: [NTG-context] index entries postponed if sections are empty

[Otared Kavian]

Hi Hraban,

Maybe you can add some « virtual » text in the section with an invisible color 
such as
\startcolor[white] a \stopcolor
I don't know whether the following can solve your problem, but the entries of 
the index appear correctly:

\usemodule[visual]

\starttext

\dorecurse{5}{%
\startchapter[title={\recurselevel}]

\dorecurse{5}{%
\startsection[title={\fakewords{3}{5}}]
\startcolor[white] a \stopcolor
\index{Something}\index{A\recurselevel}

}

\stopchapter
}

\completeindex

\stoptext

Best regards: OK

[NTG-context] Is synctex broken in lmtx ?

[Otared Kavian]

Hi Hans,

It seems that 
\setupsynctex[state=start]
does not have any effect in LMTX version 2020.09.20 23:02, while it works fine 
with mkiv version 2020.06.25 10:55.

Re: [NTG-context] Modules installation in a ConTeXt LMTX distribution

[Otared Kavian]

Hi Tommaso,

I met the same problem at the beginning of LMTX and I used a workaround: I 
copied manually the folder (in MacOS speaking, or directory) 

context-minimal/tex/texmf-modules

in my ConTeXt standalone mkiv directory, to the corresponding location in my 

/context-osx-64/tex/

Another possibility is to make a symlink in /context-osx-64/tex/ to the folder 
context-minimal/tex/texmf-modules

… Which shows that some things don't change in ConTeXt :-)

Kidding aside, why is there a difference between the tabulate mechanism and the 
xtable mechanism?

Oops… indeed. I was stupid to copy-paste \setupmathematics from another test 
file, without paying attention to « default=normal ».
The resaon for which I did this copy-paste was that with 
\definefontfamily [mainface] [mm] [STIX Math] [rscale=1.10]
the upper bound of the integral is misplaced and I don't know how to fix it.
In the archives I saw that there is « mathnolimitsmode » which can be added as 
a font feature, but its values and how to set it up are far from being clear to 
me.

Thank you so much for your help: Otared K.

Re: [NTG-context] \dorecurse{}{} problem

Hi Dalyoung,

I don't know why \recurselevel returns 0 inside a tabulate environment, but the 
following works fine:

\starttext
\startxtable[frame=off,bottomframe=on,width=1cm,align={middle,lohi}]
\startxrow\startxcell \stopxcell\stopxrow % just to have a line on the top of 
the first row
\dorecurse{8}
   {\startxrow\startxcell \recurselevel \stopxcell\stopxrow}
\stopxtable
\stoptext

[NTG-context] Math fonts for Nimbus fonts

[Otared Kavian]

Hi,

I wish to use the Nimbus fonts, but since I didn't know which Math fonts is 
best adapted to this family, I tried several fonts such as Stix Math, TeX Gyre 
Math, and so on, but doing this the math-italic does not appear in these fonts: 
does this mean that I have to set explicitely math-italic in definefontfamily?

Also what is the best math font adapted for Nimbus?

Below is my definition of a fontfamily for Nimbus fonts.

Thanks in advance for any help: Otared K

%% begin definefontfamily-nimbus.tex
\definefontfamily [mainface] [rm] [Nimbus Roman No9 L]
\definefontfamily [mainface] [ss] [Nimbus Sans L] [rscale=0.85]
\definefontfamily [mainface] [tt] [Nimbus Mono] [features=none,rscale=0.95]
\definefontfamily [mainface] [mm] [STIX Math]

%\definefontfamily [mainface] [mm] [Asana Math]
%\definefontfamily [mainface] [mm] [Lucida Bright Math OT]
%\definefontfamily [mainface] [mm] [TeX Gyre Termes Math]
%\definefontfamily [mainface] [mm] [XITSMath]

\setupmathematics[integral=nolimits,lcgreek=normal,default=normal]


\setupbodyfont[mainface]

\starttext

{\rm\tf Regular \it Italic \bf Bold \bi BoldItalic}

{\ss\tf Regular \it Italic \bf Bold \bi BoldItalic}

{\tt\tf Regular \it Italic \bf Bold \bi BoldItalic}

And here are a few math formulas $\alpha^2 + \beta^2 + \gamma^2 = x^2 + y^2 + 
t^2$.
\startformula
\int_{0}^{2\pi} \sin(x)dx = 0, 
\qquad {\rm e}^{{\rm i}\pi} + 1 = 0, 
\qquad \sum_{n=1}^{\infty}{1 \over n^2} = {\pi^2 \over 6}.
\stopformula

\stoptext
%% end definefontfamily-nimbus.tex

Re: [NTG-context] Error setting up ConTeXt in MacTeX 2020

[Otared Kavian]

Hi Felix,

Some time ago I encountered the same problem and we had a thread on this list 
about this:

https://www.mail-archive.com/ntg-context@ntg.nl/msg95355.html

The problem on my Mac came from the fact that a directory
/opt/local/etc/texmf/
existed (installed by MacPorts, without me knowing it…) where ConTeXt tries to 
find a format, while there is none.
I removed that directory and then I could use ConTeXt from MacTex 2020.

Best regards: Otared

Re: [NTG-context] latest lmtx

[Otared Kavian]

Hi Alan,

Where did you install LuaMetaTeX? 
For instance my LuaMetaTeX.engine contains the following three lines:

#!/bin/bash

export 
PATH=/context-osx-64/tex/texmf-osx-64/bin:/context-osx-64/bin:/context-osx-64/tex/texmf-osx-64/bin

/context-osx-64/tex/texmf-osx-64/bin/mtxrun --autogenerate --script context 
--directives="system.showerror" --autopdf "$1" --purgeall

where I am invoking the file 
/context-osx-64/tex/texmf-osx-64/bin/mtxrun
which is in the folder context-osx-64 where I installed LuaMetaTeX by running 
sh install.sh

Therefore your LuaMetaTeX.engine file should contain the correct path.

Best regards: Otared

Re: [NTG-context] defining font family for several options

[Otared Kavian]

Hi Julian,

What Aditya means is that you define two (or more) font families: one is named 
mainface as yu have already done, the other named mychapterfont (for instance) 
where you attribute whatever fonts you wish to sans serif and else. Then when 
you want to use the special font in some of the titles you use

{\switchtobodyfont[mychapterfont]\ss my text}

You can use also

\start \switchtobodyfont[mychapterfont] \ss my text \stop

in case the braces are not convenient for a longer text.

Best regards: Otared

Re: [NTG-context] Overriding the number on a float

[Otared Kavian]

Hi,

If there are a few special numberings of floats, and one wants floats numbered 
1.6a and 1.6b, the following seems to work:

Best regards: Otared

\stopsection

\startsection[title=Two]
\startplacefigure[title=Test]
\externalfigure[dummy]
\stopplacefigure
\stopsection

\setcounter[figure][5] % next figure is no.6

\startsection[ownnumber=10,title={A section}] 
\start
\setupcaptions[numberstopper={a}]
\startplacefigure[title=Test figure]
\externalfigure[dummy]
\stopplacefigure
\stop
\stopsection

\setcounter[figure][5]

\startsection[ownnumber=11,title={Another section}] % ownnumber doesn’t work
\start
\setupcaptions[numberstopper={b}]
\startplacefigure[title=Test another figure]
\externalfigure[dummy]
\stopplacefigure
\stop

\startplacefigure[title=Test another figure]
\externalfigure[dummy]
\stopplacefigure

 I think there was a question on this very recently but I don;t think it

 for two figures in a particular chapter to become 27.1a and 27.1b instead 
 of 27.1 and 27.2. It's not a combination - they are separate figures on 
 different pages.
 
 I've experimented with the options I can see, but it's not obvious if 
 there is a facility to override the numbering of two figures in a stream 
 of normally numbered figures like this. I was thinking of the equivalent 
 of the old \sym{symbol} command that used to work as a way to override a 
 single item in an otherwise sequential list.
 
 I guess there's a brute force method of setting up a new type of figure 
 with the label "Figure 27.1" and having them numbered as lowercase alpha, 
 but if there's an easier way that would be great.

Re: [NTG-context] Chapter heading with rules

[Otared Kavian]

Hi Julian,

Indeed you can acchieve what you want, but it is better to define a command 
which takes care of the number and the title of the chapter at the same time 
(as in \ myChapterCommand below).

%% begin example.tex
\definefiller[ChapterRule]
[alternative=rule,
color=gray,
height=0.8ex,
depth=-0.6ex]

\definefiller[ChapterLeftRule]
[ChapterRule]
[left=\zerowidthnobreakspace,
right=\quad]

\definefiller[ChapterRightRule]
[ChapterRule]
[left=\quad,
right=\zerowidthnobreakspace]

\define[2]\myChapterCommand{%
\midaligned{{\filler[ChapterLeftRule]}#1.~#2{\filler[ChapterRightRule]}}
}

\setuphead[chapter]
[textstyle={\setcharactercasing[WORD]\ssa},
command=\myChapterCommand]

\starttext

\startchapter[title={My Chapter Title}]
\input knuth.tex
\stopchapter

\stoptext

%% end example.tex

Best regards: Otared K.

Re: [NTG-context] memoir-style chapter heading

[Otared Kavian]

Hi Julian,

Indeed you can modify slightly what Aditya said to obtain what you want: you 
can put the overlay into a framed environment as in the following example. 
Though, to my taste the number is a little bit too low…

%% begin example
\setuppagenumbering[state=start,location=footer]
\setuphead[chapter]
[
numberstyle={\switchtobodyfont[48pt]},
numbercolor=gray,
alternative=command,
command=\MemoirChapter,
]

\define[2]\MemoirChapter
{\framed[frame=off,width=broad,align=middle]
{\startoverlay
{#1}
{#2}
\stopoverlay}
}

\starttext
\startchapter[title={This is a test}]
\input knuth.tex

\stopchapter

\stoptext
%% end example

Best regards: Otared

sure to be able to run ConTeXt from TeXLive2020 in order to convince a few 
colleagues to experiment it with TeXShop. 

If I type in the Terminal
port installed 'tex*'
the answer is:
None of the specified ports are installed.

I guess this is because after having solved the problem I met with installing 
MacTeX2020, I had done:
sudo port uninstall texlive-basic --follow-dependencies
in order to uninstall ant TeX related package from Macports (I don't know how 
thos packages were installed, maybe when I tried to use asymptote, and since I 
couldn't use it from within ConTeXt I gave up…).

Re: [NTG-context] How can I use ConTeXt from TeXLive2020 ?

[Otared Kavian]

Dear Axel,

Thank you very much for your attention and your hints, which solved my problems 
with ConTeXt from TeXLive2020.

Indeed following your suugestion, I removed the 
/opt/local/etc/texmf/
directory, as well as all other tex related directories and files in 
/opt/local/, and then installed again MacTeX2020. 
In oder to be on the safe side, I rebuilt also the locate database, then 
rebooted my machine: after that I could  run
luatools --generate
and now with
context --version
 I have current version: 2020.03.10 14:44.

However I don't know why I had tex related files in /opt/local/, which is used 
by MacPorts…

I hope to be able to explain to my colleague how to run ConTeXt (LuaTeX) within 
TeXShop from MacTeX2020.

Thanks to eveyone!

Best regards: Otared

Re: [NTG-context] How can I use ConTeXt from TeXLive2020 ?

[Otared Kavian]

Hi Hans,

Thanks for your explanations, which clarify why sometimes ConTeXt may not work 
straight of TeXLive.
Nevertheless I will contact the people who maintain MacTeX in order for them to 
be aware of the issue I encounter, so that hopefully in the future releases 
people would be able to use ConTeXt from MacTeX.

Best regards: Otared

I don't have these files at this place, but in
/opt/local/etc/texmf/
I do have 
/opt/local/etc/texmf/texmf.cnf
/opt/local/etc/texmf/texmfcnf.lua
the first one being created automatically when I tried to do mtxrun --generate 
after installing TeXLive2020. Ir says its content should not be modified 
directly and that its content is based on of the file
/opt/local/etc/texmf/texmf.cnf.d
The content of the above directory dates from 2019, and maybe that is why my 
logfile reports things being done with TeXLive2019. 

The content of the file 
/opt/local/etc/texmf/texmfcnf.lua
is written by Hans in date = "2012-05-24" time = "12-12-12".

Replacing /opt/local/etc/texmf/texmf.cnf with some other texmf.cnf does not 
help, since it is overwritten when one does 
mtxrun --generate

So the problem remains… Maybe I have to contact people who prepare MacTeX2020 
and ask for help with them.

Thank you agin for your time and advices.
Best regards: Otared

I did update TeXLive with TeX Live Manager. But still I cannot run ConTeXt from 
TeXLive2020 (neither from TeXShop nor from Terminal).

> […]

I checked for the existence of directories of the type .texlive2020: there is 
no such directory in my home directory.
There were three leftover directories .texlive2008, .texlive2010 and 
.texlive2019, which I removed.
Doing 
mtxrun --generate
creates a .texlive2019 directory which contains some other folders which are
texmf-var/luatex-cache/context/88aacfe88c3cbee9a12d5f4bec4da90b/trees/
and in the latter folder there are 10 files with suffixes .lua and .luc.
Again 
context test.tex
results in 
mtxrun | unknown script 'context.lua' or 'mtx-context.lua'

So the problem remains…

Hi Hans and Taco,

Thanks for the help!
Doing

Doing

Re: [NTG-context] How can I use ConTeXt from TeXLive2020 ?

[Otared Kavian]

Hi Alex,

Thank you and Taco for helping. 
In order to help solve the problem of running ConTeXt from MacTeX, I installed 
MacTeX2020 (which is the same as TeXLive2020). Now if in a Terminal window I do
which context
the answer is:
/Library/TeX/texbin/context
And the answer to
which pdflatex
is
/Library/TeX/texbin/pdflatex
Also the answer to:
which luatools 
is
/Library/TeX/texbin/luatools

So the binaries are in /Library/TeX/texbin, which is in fact an alias for
/usr/local/texlive/2020/bin/x86_64-darwin

Now, as you and the « ConTeXt (LuaTeX) » engin suggest, if I do
luatools --generate 
then the answer is:
mtxrun | unknown script 'base.lua' or 'mtx-base.lua'
It is possible that the version of mtxrun or luatools scripts in TeXLive are 
not working.

I don't remember what I did with TeXLive2019 to fix the issue, but my concern 
is that if including ConTeXt in TeXLive is intended for people to use it, then 
it SHOULD run without such tweakings which, even for someone who is a regular 
user of ConTeXt, are not easy to find.
The solution consisting of installing a standalone tree of ConTeXt, is not a 
real solution because many people do not know how to do it and, even if they 
could, then what would be the point of doing so much work for people who 
include a ConTeXt tree in TeXLive?

Anyway, I apologize for my acrimonius remarks, and I thank you again for your 
help.

Best regards: Otared

[NTG-context] How can I use ConTeXt from TeXLive2020 ?

[Otared Kavian]

Hi all,

I suggested to a friend, who is using plain TeX and LaTeX, to switch to 
ConTeXt, and since he is using TeXShop on MacOSX with a version of TeXLive2020 
(named MacTeX2020), I thought he would just typeset a simple test document with 
the option « ConTeXt (LuaTeX) » from the menu in TeXShop, where it does appear.

Unfortunately when doing this all he gets in the log file is:

/sw/bin/init.csh: No such file or directory.
mtxrun  | unknown script 'context.lua' or 'mtx-context.lua'

and I could not help him make the format (I do not have access to his machine, 
and I was trying to explain what to do on the phone).

He cannot (or does not want) to install a standalone version of ConTeXt, and he 
thinks that since ConTeXt exists in TeXLive2020 it should work out of the box, 
as do plain TeX and LaTeX. My opinion is that he is right… But since for the 
tim ebeing this is not the case, can anyone explain what to do in order to 
enable ConTeXt running from TeXLive2020?

Thanks in advance for any help: Otared K.

[NTG-context] Defining \qed (was: Bug with \wordright...)

[Otared Kavian]

Hi Wolfgang,

Thanks for your explanations and the correct definition of the close symbol in 
an enumeration.
Following up the discussions with Hans, in order to put a close sympbol at the 
end of a formula, I have the following for the definition of \qed:

%% begin example-qed.tex
\showframe
\definesymbol[Fin][\mathematics{\square}]
\def\qed{%
\ifmmode
\inrightmargin{\hskip-7.5mm\symbol[Fin]} % --> attention here
\else
\dontleavehmode\wordright{\symbol[Fin]}
\fi}

\setupformulas[location=left]

\starttext

One sees that
\placeformula
\startformula
   a^2 + b^2 = c^2
\stopformula
which is the Pythagoras theorem. \qed

Another proof of Pythagors theorem is based on the figure below in which one 
sees that:
\placeformula
\startformula
(a+b)^2 = c^2 + 2ab \quad \imply \quad a^2 + b^2 = c^2. \qed
\stopformula

\stoptext
%% end example-qed.tex

Now how can I replace « \hskip-7.5mm » (which was found by trial and error…) in 
a robust manner so that the close symbols in the formulas are vertically 
aligned with the close symbols in the text?
In other terms can one compute automatically the amount of negative \hskip so 
that the definition is correct when one changes the font size and the layout?

Thanks in advance: Otared

Re: [NTG-context] Bug with \wordright in LMTX version 2020-08-03 14:25

[Otared Kavian]

Hi Hans,

Thanks for the hint which consists in adding an \ifmmode to the definition of 
\qed.
However, as you suggest, one needs some other mechanism in math mode, since 
with your new definition of \qed the alignment of the formula changes when one 
adds this close symbol:

 begin-example-qed.tex
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\ifmmode\quad\symbol[Fin]\else\strut\wordright{\symbol[Fin]}\fi}
\starttext
\startformula
a^2 + b^2 = c^2.
\stopformula
\startformula
a^2 + b^2 = c^2. \qed
\stopformula
One sees that\type{\qed} in the formula changes the alignment of the formula. 
\qed 
\stoptext
 end-example-qed.tex

Thanks a lot for everything: Otared

[NTG-context] Bug with \wordright in LMTX version 2020-08-03 14:25

[Otared Kavian]

Hi Hans,

A file which used to be typeset correctly with the previous versions of lmtx, 
now produces an error. Despite the error message being extremely cryptic:

Error  ! Missing number, treated as zero

I could guess the origin of the bug, which seems to be \wordright,  but 
although the following minimal example shows a bug it does not produce the same 
ERROR output page:

 the square ''end of proof''
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\wordright{\symbol[Fin]}}

\starttext
\startformula
a^2 + b^2 = c^2
\stopformula
\qed % the problem is here
\stoptext

In the above example if one adds something before \qed, then the square 
end-of-proof appears. 
However in my real file ConTeXt ouputs an error page and says: Error   ! 
Missing number, treated as zero.

Best regards: Otared

Re: [NTG-context] margin notes (was: lmtx update)

[Otared Kavian]

Hi Hraban,

Thanks for the hint… indeed I did see that \ColWidth command but didn't think 
about its definition… Sorry!

Now with \ColWidth defined, your code works fine and it has the advantage that 
the text of the sidenote begins in the margin at the level where the \footnote 
command appears. However, it cannot control the overflow of a sidenote to the 
next page, whereas the code given by Hans can do that. I admit that this does 
not happen very often since a well designed text should not have too many long 
sidenotes…

In case other users would like to use your code, I put the whole example below.

Best regards: Otared
%%% sidenotes, or footnotes in the margin
%%% example given by Hraban:
%%% here the tweaking of the width of the sidenote is turned off
%%% remove the comment where there is \ColWidth
%%% in order to adapt to your layout

\def\FNVOffset{0} % Negative vertical offset of footnotes in lines
% Manual tweaking was necessary for a while, when stacking didn’t work reliably.

\def\MarginNote#1{%

Re: [NTG-context] margin notes (was: lmtx update)

[Otared Kavian]

Hi Hraban,

Thank you for taking the time to send your code for sidenotes.
Unfortunately when I add

\starttext
test\footnote{A footnote in the margin.}
\stoptext

to your code, I get an error and unfortunately with recent versions of LMTX the 
error message 
!  Undefined control sequence
is not helpful to find the error… (LMTX considers \footnote as an undefined 
control sequence…).

Best regards: Otared
