[NTG-context] Re: Japanese

[Jeong Dal via ntg-context]

Hi,

In Korea, LaTeX is popular rather than ConTeXt since mathematicians initiated 
the use of TeX in Korea and they use LaTeX mainly.
But right now, there are so many non-math people who developed many things for 
Korean & LaTeX.

Many years ago, Hans and Taco visited the seminar held by KTUG.
They discussed with the experts KTUG about to use Korean.
From then, there are many progress to use Korean in ConTeXt. 
Now, I am using ConTeXt to produce textbooks and manuals in Korean with 
pleasure.
Unfortunately, there is a little problem in spacing, for example, “)  ,”.  It 
is rare case, so I can  correct it manually without problem.

In general, ConTeXt typesets Korean nicely. 
Thanks Hans and ConTeXt team.

For Koreans, I use

\mainlanguage[kr]
\setscript[hangul]


The rule of line break are very similar to that of Japanese. 
I think that “hangul” script handles it and other things.

I am just a user of ConTeXt, but if you need any information about Korean to 
enhance the usage of Korean in ConTeXt, please let me know.

Thanks again to Hans, team, and people in this list.

Best regards,

Dalyoung

[Jeong Dal via ntg-context]

Dear Otared,

I am using Korean as main language.
I used use typescript file, but recently I use \definefontfamily.
Since using Japanese font is similar to use Korean font, I show my example  of 
using Noto fonts. It was made by the help of expert of this list long time ago.

You may change "Noto Serif CJK KR” to Japanese font.

I also use "\setscript[hangul]” when I use Korean as mainlanaguage.

I hope that you may enhance the following code.

Best regards,

Dalyoung


%%% Noto Fonts

\definefontfamily[notoFont][rm][Noto Serif CJK KR]
  [   it={style:regular,features:{*,slanted}},
  sl={style:regular,features:{*,slanted}},

[NTG-context] Re: \startcolumns and \startcolumnset

[Jeong Dal via ntg-context]

Dear Otared,

Thank you for testing.

I run the sample after changing the column command to ‘\startsimplecolumns … 
\stopsimplecolumns’.

I got the same result as  your output. And it is same as the result using 
\startcolumns … \stopcolumns.

If ‘\vfill’ works, then it is OK for me, but it isn’t.

It works under the command “\startcolumnset … \stopcolumnset”.
But there are another problem under the ‘columnist’ command.

I’ll read the manual of columnset carefully.

Best regards,

Dalyoung

[NTG-context] \startcolumns and \startcolumnset

[Jeong Dal via ntg-context]

Dear all,I have a little problem to use “columns” in the following example.If I use “\startcolumnset”, then I have the following problems:	1. The figures is aligned left even though I use \startplacefigure[].	2. In the second column, the first item located at the end of the page.However, \vfill works, so I managed the items evenly spaced vertically.If I use “\startcolumns”, then I have the following problems:	1. \vfill doesn’t works, but \blank[] works. So, it isn’t easy to locate the items evenly spaced vertically.Here are sample code and its outputs of two cases for comparison.Any suggestions are welcomed.Tomorrow is the New Years day in Lunar calendar.Happy new year, again.Best regards,Dalyoung%%%\startuseMPgraphic{mark}path p;p := unitsquare scaled 3cm;draw p;draw (point 0 of p)--(point 2 of p);draw (point 1 of p)--(point 3 of p);\stopuseMPgraphic\startuseMPgraphic{verticalrule3}   draw rightboundary OverlayBox shifted (1mm,0); %if CurrentColumn = 1: shifted(-2mm,0) fi ;   draw leftboundary OverlayBox shifted (-1mm,0); %if CurrentColumn = 2: shifted(2mm,0) fi ; draw bottomboundary OverlayBox leftenlarged 1mm rightenlarged 1mm;   draw topboundary OverlayBox leftenlarged 1mm rightenlarged 1mm;\stopuseMPgraphic\defineoverlay  [verticalrule]  [\useMPgraphic{verticalrule3}]\setuppagenumbering[state=stop]\setupexternalfigures[location={local,defalut}]\definecolumnset  [quiz]  [n=2,background=verticalrule]\setupbodyfont[bonum, rm, 11pt]\starttext %\startcolumns[n=2,background="">\startcolumnset[quiz]\startitemize[n]  \item Solve the following linear equations.  \startitemize[r]\item equation%\blank[3.5cm]\vfill\item equation%\blank[3.5cm]\vfill\item equation\blank[3.5cm]\item equation\blank[3.5cm]\item equation\blank[3.5cm]  \stopitemize  \hrule\column  \item Draw the graph of the following linear function.\startitemize[r]\item $2x +3y = 6$\startplacefigure[location={here,none},]\useMPgraphic{mark}\stopplacefigure  \item $y = 2x - 1$  \startplacefigure[location={here,none}]\useMPgraphic{mark}\stopplacefigure\stopitemize  \item Find the formula of the line 1:  \vfill  \item Find the formula of the line 2:  \vfill\stopitemize\stopcolumnset\stoptext%%

Dear Otared,

I installed upload version today.
And, your example,

\starttext
The derivative of $f$ is denoted $f'$ or $f^\prime$ or is it $f^'$\dots
\stoptext

works well.

I think that you will have the same good result.

Best wishes,

I tried to draw a flow chart using the module[chart].
Following the examples, I draw one.

The problem is that the size of the chart is not changed even though I changed 
the numbers dx,dy, width, height, and maxwidth in the \setupFLOWcharts

Please tell me how to resize the chart.

Thank you.

[NTG-context] Re: wiki update: Modules

[Jeong Dal via ntg-context]

Dear Hraban,

When I wrote a class material for Linear Algebra, it is nice to use \pmatrix 
and \bmatrix etc. 
But, for example, to write a result matrix of the product of two matrices, I 
need to calculate it somewhere and copy it to my text. Hence, I tried to use 
Lua to handle it in the ConTeXt. And, it is nicely working.
During the process, I asked many questions to Hans and he gladly helped me.
It is the first time for me to code using Lua, so my coding was clumsy. 
However,  Hans corrected it to be usable in ConTeXt even though he is very very 
busy in many things.
And, he made it a module and put it in the list.
Thanks Hans.

Finally I finished several chapters on Linear Algebra using that code.
It was many years ago.
Here is a document of it. I confirm that it is running well without any problem.

I hope that someone who wants to write an article on Linear Algebra use it.

Thanks for reading.

Best regards,

Dalyoung

Re: [NTG-context] Chapter title in MetaFun manual.

[Jeong Dal via ntg-context]

Dear all,
 
I think that I found the cause.
The page layout of my file is different from that of MetaFun manual.
After borrowing the \setuplayout from MetaFun-000.tex, it works correctly.

I am sorry to give you a wrong example.

Thank you for reading.

Best regards,

[NTG-context] Chapter title in MetaFun manual.

[Jeong Dal via ntg-context]

Dear all,

I copied the code of defining chapter command  from metafun-000.tex, and run it.
But the result is different from that in MetaFun Manual.
There is a big spaces between the number and the title which yields the number 
cannot be seen.
I commented out several lines which seems to be not-related with chapter title.
And, I changed

\def\ChapterCommand#1#2% —> \define[2]\ChapterCommand

Would you please test the following code to find out what is wrong?

Thank you for reading.

Re: [NTG-context] Bug in math alignment

[Jeong Dal via ntg-context]

Dear Otared,

> 
> 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.
> 

I confirm what you said.

However, if I use \dm{} instead of \displaystyle as following, then the output 
is correct.

\placeformula
\startformula
\startalignedcases
\NC - \Delta u \NC = 0 \NC \qquad\text{in }\, \Omega \NR
\NC  \dm{\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  \dm{\frac{\partial u}{\partial {\bi n}}}
 \NC = V u + \phi \NC \qquad\text{on }\, \partial\Omega. \NR
\stopalignedcases
\stopformula

In this example, it is OK to use \dm inside of \startformula … \stopformula.
I am not sure that it is what Hans and Mikael want.

Thanks,

Best regards,

Dalyoung

Thank you for your concern.
When we write  two long formula, I think that to use "\alignhere, \breakhere" 
is a little bit simpler than use \NC\NR.
We may write them to use \startformula…\stopformula twice separetely. 
But, then the alignment of two formulas may be different because formula’s 
alignment is midaligned. 

Thanks again to add it todo list.

[NTG-context] Math alignment question

[Jeong Dal via ntg-context]

Dear Mikael and Hans,

Recently, you introdued the new command “\alignhere, \breakhere, \skiphere” 
which works fine.

Since I usually use the following code that is adopted from My 
Way(Mathalign.pdf), I’d like to know that there is a way to use “\alignhere, 
\breakhere, \skiphere”  for the case below?

\startformula\startalign
\NC A \NC = 3   \NR
\NC B \NC = 5 \NR
\stopalign\stopformula

Thank you.

[NTG-context] \startcolumnset ... \stopcolumnset is working.

Dear all,

I didn’t test “\startcolumnset … \stopcolumnset” for some time, because I got 
error whenever I tested it under Mac OS Big Sur. 

However, two days ago, I tested it, and found that it was working.
I install updated version today and run a test file again.
Finally, I get an output without error!

I don't know what is happened, but it is a good news.

Here is a sample file which I simplified one that is given by one of the 
experts.
Someone may modify it better.

Thanks to ConTeXt team.

Re: [NTG-context] update

[Jeong Dal via ntg-context]

Dear Hans, Mikael,

The alignment problem which occurred when I put aligned formulas and a figure 
side by side is solved.

Thank you for the update.

Best regards,

Re: [NTG-context] Cron /var/www/aanhet.net/context/bin/cron/context-mirror

[Jeong Dal via ntg-context]

Dear Hans,

Thank you for the new way to align math formulas.
It is great to use “\alignhere”, “\breakhere”.

However, I got a problem today.
If I use it with figures side by side, then the alignment is broken.

Please try the following MWE.

Best regards,

Dalyoung


\setupexternalfigures[location={default,local,global}]

\starttext
\startplacefigure[location=right,]
\externalfigure[cow][width=.3\makeupwidth]
\stopplacefigure
\startformula
 U(f,P) \alignhere = f(2,2)\Delta A_{11}+f(2,3)\Delta A_{12}\breakhere
  \skiphere[1em] +f(3,2)\Delta A_{21}+f(3,3)\Delta A_{22} \breakhere
  = 4\times 2 + 6 \times 1+ 6 \times 2 +9 \times 1  \breakhere
  = 35.
\stopformula
\stoptext

Re: [NTG-context] new upload

[Jeong Dal via ntg-context]

Dear Hans,

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

Thank you.

Re: [NTG-context] new upload

[Jeong Dal via ntg-context]

Dear Hans,

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

This code was working in last December. 

Thank you for your fix.

Best regards,

Dalyoung

[NTG-context] $\sin \theta$ behave differently in metafun

[Jeong Dal via ntg-context]

Dear all,

I use $\sin \theta$ and $\cos \theta$ behave differently in text and in metafun.
It works well sometime before but it doesn’t  in metafun now.
What is wrong in my example?

Thank you for reading.
Best regards,

Dalyoung

Here is a MWE.

\startbuffer[pointCircle]
numeric u; u:=1cm;
pair A,B,C;
draw fullcircle scaled 4u;
A := dir(25)*2u; 
label.top(textext("$P=(\cos\theta, \sin\theta)$"), A);
B := dir(-25)*2u;
label.bot(textext("$Q=(\cos(-\theta), \sin(-\theta))$"), B);
C := (xpart A, 0); label.lrt(textext("$A$"), C);
label(textext("$O$"), origin);
\stopbuffer
\starttext
I'd like use $\sin$ and $\cos$ in the metafun. But it shows strange text 
instead of $\sin$ and $\cos$. 

\processMPbuffer[pointCircle]

\stoptext

Re: [NTG-context] context manuals -- absence of \definefontfamily

[Jeong Dal via ntg-context]

Dear Aditya and Youssef Cherem,

To: Aditya,
> 
> There is the talk that Wolfgang gave in this year's context meeting:
> 
> https://meeting.contextgarden.net/2021/talks/2021-09-23/definefontfamily.pdf
> 
Thank you for letting me know the talk which gives me more understanding about 
\definefontfamily.

To: Youssef Cherem,

Recently, Wolfgang helped me to define a font family as following, and I hope 
that it gives you some idea to use \definefontfamily.

\definefallbackfamily [nanum] [rm] [Tex Gyre Pagella]
  [range={basiclatin,latinsupplement,latinextendeda,latinextendedb}, 
   force=yes]
\definefallbackfamily [nanum] [rm] [Noto Serif CJK KR]
  [range={cjkunifiedideographs},force=yes]
\definefontfamily [nanum] [rm] [Nanum Myeongjo OTF]
  [   it={style:regular,features:{*,slanted}},
  bi={style:bold,features:{*,slanted}},force=yes]

Explanation:
1. I use Korean font whose family name is “Nanum Myeongjo OTF” as main font. 
Since it doesn’t have italic style and bold italic style, I add [it=… , bi=…] 
to simulate the styles.

2. Since I want to use English character in "TeX Gyre Pagella”. I add it in the 
first \definefallbackfamily with an option [range={…},force=yes] which restrict 
the use of font to Latin characters.

3. We use chinese characters also in the Korean sentences. But "Nanum Myeongjo 
OTF” doesn’t have Chinese characters. So I add another font “Noto Serif CJK KR” 
which contains Chinese character with the option 
[range={cjkunified…},force=yes] in the second \definefallbackfamily.

There are two font families more,  sans and mono which is similar as rm.
It is really nice to use \definefontfamily which saves a lot of work to define 
fonts. 

Thanks Wolfgang.
If there are something should changed in the above definition, please tell me 
what to do.

Best regards,

Dalyoung

Re: [NTG-context] upload

[Jeong Dal via ntg-context]

Dear Hans,

I installed the new upload and compiled “helloWorld.tex” created Sanjoy Mahajan.
It runs well except  the dummy figures are not appeared in the pdf output.

However, I still got error message when try to compile “\startcolumnset … 
\stopcolumnset”.

fonts   > 'fallback modern-designsize rm 12pt' is loaded
mtx-context | fatal error: return code: 1
The terminal process "zsh '-c', 'mtxrun --autogenerate --script context 
--autopdf --purge '/Users/graph/Library/Mobile

1.

As you see in the log file, "return code: 11" is changed to “return code: 1”.

It might be the problem of system environment as you said.

Thank you.

Merry Christmas and Happy new year!

[NTG-context] \startcolumnset ... \stopcolumnset fatal error: return code 11

[Jeong Dal via ntg-context]

Hi,

I have used newcolumnset module to make a test sheet. It was made by the help 
of experts in the list.
It worked fine a month ago and also worked via TeXlive 2021.
But I got error using the recent version.
Thanks Nicola and John for testing.

I have listed it before and tried to find out the cause.
I have test the following file in the editors,  vscode, vim, atom and even in 
the terminal.
It might be an apple binary problem as Hans suspected.
I’d like to know that it is the only problem for Mac users.

Here is the code and the part of error message:
It was tested in vscode, vim and terminal too.

I am using Mac OSX, 
ConTeXt  ver: 2021.12.03 15:20 LMTX  fmt: 2021.12.9  int: english/english

Thank you for reading.
Best regards,

Dalyoung

Dear Nicola, Jan-Erik, and John,

Although you have explained about the way out of my problem, 
I am still in the problem.

I need to learn more about vim.
I’ll do more try following your advice and  the explanation in wiki.

Re: [NTG-context] how to setup path of ConTeXtLMTX for MacVim?

[Jeong Dal via ntg-context]

Dear John, Nicola,

I created a file context.vim under the folder ~/.vim/after/ftplugin/ which 
contains

map > :w:!ConTeXt
let g:context_mtxrun = 'PATH=$HOME/ConTeXtLM/tex/texmf-osx-64/bin:$PATH mtxrun'
let g:tex_flavor = "context"

The result is
1. using “:ConTeXt”   issued an error message:  “E492: not an editor command: 
ConTeXt
2. using “make” issued an error message: "No targets specified and no makefile 
found. …" 
Pressing C-h, compiling started and succesfully ended. However, it use 
/usr/local/texlive/… not LMTX tex folder.

Without context.vim, “:ConTeXt" and “:make" worked fine.

I’ll do more test. 

Thank you.
Best regards,

Dalyoung

[NTG-context] how to setup path of ConTeXtLMTX for MacVim?

[Jeong Dal via ntg-context]

Hi,

Recently, I have a problem to use vscode, so I tried MacVim for ConTeXt.
It worked fine. But it uses context in TeXLive instead of using it in 
ConTeXtLMTX.
I’d like to use LMTX which is installed in ~/ConTeXtLM/tex/...

How to redirect the path for ConTeXt in MacVim?

Thank you.

Best regards,

Dalyoung

Re: [NTG-context] using the newcolumnsets module

[Jeong Dal via ntg-context]

Dear Hans, Bruce Horrocks,

I test the file using MacVim and confirm that it works fine.
Thus, something happened in my system or environment of vscode.
I may reinstall vscode.

Thank you.

Re: [NTG-context] using the newcolumnsets module

[Jeong Dal via ntg-context]

Dear Bruce Horrocks,

Thank you for your test.
I have moved the file to the local and run it. But the result is same.
However, since your try worked well, the problem is mine not LMTX.
I am using the editor “vscode”, and there may be something changed in my system 
recently.

I’ll try using other editors.
Thank you.

Best regards,

Dalyoung

I am running LMTX now.
It opens and closes  "*-newcolumnsets.mkiv” files(we can find the lines in the 
log file).
I also tested the  files which had no problem a month ago, but got the same 
error message now.

I reinstalled context and test it. 
But the result is same.

I am going to test it more.

Thank you.

[NTG-context] using the newcolumnsets module

[Jeong Dal via ntg-context]

Dear all,

I made an exam form by the help of the experts in this list.
However, it was not working after recent update.
Here is a code which I made for the test.
If I use “\startcolumns \stopcolumns”, then it has no problem.
But using “\startcolumnset[exam] … \stopcolumnset” produces error message 
“return code 11”.
It loads “m-newcolumnset.tex” without problem.

What is the cause of this error?

Thank you for reading.

Best regards,

Dalyoung

Both of your methods are working well.

Re: [NTG-context] weekend upload - stacking and animation

[Jeong Dal]

Dear Hans, Aditya,

Now, I understand the stacking method.
I made a simple animation using it.


\startuseMPgraphic{demo}
  for i=1 upto 10:
  draw fullcircle scaled (.3*i*cm)  withcolor (.1*i*red) withpen  pencircle 
scaled (.5*bp) withstacking i;
  endfor;
\stopuseMPgraphic
\setupinteraction[state=start]
\usemodule[animation]

\starttext
\startanimation[menu=yes]
%  \dorecurse{10}
%  { {\useMPgraphic[stacking={#1}]{demo}}}
  {\useMPgraphic[stacking={1}]{demo}}
  {\useMPgraphic[stacking={2}]{demo}}
  {\useMPgraphic[stacking={3}]{demo}}
  {\useMPgraphic[stacking={4}]{demo}}
  {\useMPgraphic[stacking={5}]{demo}}
  {\useMPgraphic[stacking={6}]{demo}}
  {\useMPgraphic[stacking={7}]{demo}}
  {\useMPgraphic[stacking={8}]{demo}}
  {\useMPgraphic[stacking={9}]{demo}}
  {\useMPgraphic[stacking={10}]{demo}}
\stopanimation

However, I cannot succeed to use \dorecurse to make the code simple.
If there is another good method, please let me know.

Anyway, thanks for this new feature!

Dear Aditya,

Thank you for your code and an explanation.

I tried to reproduce your example using \startuseMPgraphic{boxes} … 
\stopuseMPgraphic, and useMPgraphic[stacking=0]{boxes} .
A modified one of your code is below.
There is no error message but no output at all.
Would you please tell me what is wrong in here?

Re: [NTG-context] Delivering the value of a variable in MetaFun to ConTeXt

[Jeong Dal]

Dear Aditya and Hans,

Thank you for your suggestion.
I add 

> \startMPcalculation
>  
> \stopMPcalculation

and it works.

\setupinteraction[state=start]
\usemodule[animation]
\starttext
%\startanimation[menu=yes]
%{
\startMPcalculation
 path p;
\stopMPcalculation
\dorecurse{\udCount}
 {\useMPgraphic{foldUD}{num=\recurselevel}}
 {\useMPgraphic{dotLines}{num=\recurselevel}}
%}
%\stopanimation
\stoptext

However, it draws all the figures under the \startanimation case.

There may be something I missed or there is something uncertain between 
\dorecurse and \startanimation.

Thank you.

1. Here is the working sample of animation using \processMPbuffer which I did 
before. You can see it using adobe reader.

   else:

   fi;
   H
   enddef;

   def grayUD(expr i) =
  draw G -- if ypart(B)=ypart(G): B -- C else: C -- B fi --z[i];
  filldraw z[i]+2*(G-z[i])*u -- z[i] -- z[i+1] -- z[i+1]+(G-z[i])*u -- 
cycle withcolor .75white;

Now, I am trying to do the same thing using \startuseMPgraphic, but I don’t the 
correct result yet.
Using \startuseMPgraphic, and \dorecurse, the code is simpler. But, it seems to 
me that \startanimation … \stopanimation is not working with \dorecurse{}{} …
It just list all the graphics.
Any hint is welcome.

[NTG-context] Delivering the value of a variable in MetaFun to ConTeXt

[Jeong Dal]

Hi,

Is there a way to deliver the value of a variable in MetaFun to ConTeXt.
For example, I want to do the following:

\starttext
\startMPcode
numeric maxCount;
% … some code
maxCount := 10;
\stopMPcode

dorecurse{maxCount}
{It is \recurselevel.\par}

\stoptext

Thank you for reading.

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

[Jeong Dal]

Dear Otared,

I received list mail in condensed form, I didn’t see your mail before I sent 
one.

As Mikael explained, “whatever” is very nice to find the intersection point of 
two lines.
You can see nice examples which use “whatever” in MetaFun manual.

In my code, the next point is the intersection point of the edge and the 
folding line which bisect the angle of the former folding line [M,N].

H := whatever[N, N + dir(.5*angle(M-N))*u] = whatever[A,B];

Enjoy the use of “whatever”!

I made an animation of the folding process using animation module and 
\processMPbuffer.
But Woldgang’s code showed a way to make it using \startuseMPgraphic.

[NTG-context] simplifying repeated macro calls in metafun

[Jeong Dal]

Hi,

I defined a macro definition in metafun, and draw figures using \startbuffer[] 
… \stopbuffer and \processMPbuffer[].
As you see in the attached code, the same macro definition is used repeatedly 
by changing the numeric argument. 
Is there a better way to simplify the code, for example, using \dorecurse and 
recurselevel?

Thank you for reading.

Re: [NTG-context] mathfun (Hans Hagen)

[Jeong Dal]

Dear Hans,

Thank you for your new module for math.

If possible, I prefer to use 
$ \sqrt(x) = \compute\sqrt[.3N] {2} $   
$ \pi = \mathexpr[.40N]{pi}$

It is more direct to use and good to write a text in which we need some math 
calculation.
It is another good news for me.
I hope it covers at least all the functions in metafun and in lua.

Re: [NTG-context] add more blank space when using \starteffect[hidden]

Dear Hans,

I found a command \determinenoflines by googling.
I made a MWE as following. It is working well.

But I have to write the paragraph twice for couning.
Is there a better way?

Thank you again.

Dear Hans,

Thank you for your answer.

>

Yes, it clears everything in the frame.
But the frame is also clean when I disable \hideSolution. In that case, texts 
should be appeared.
What I want is the following:

If \hideSolution then
hide text and add more blank spaces
else
show full text and no more space.
endif

The full text  for the students another for the lecture.

Is there a way not using \framedtext?

Thank you again.

[NTG-context] missing "{ }" in metafun.

Hi,

Set notation “{}” is OK in TeX mode.
But it is missing in the output of the metafun code.
Here is an MWE.

It is same in two different versions.

[NTG-context] add more blank space when using \starteffect[hidden]

[Jeong Dal]

Hi,

Sometimes, I need to hide the solution of a problem.
So I use \doifmode{} and \starteffect[hidden] as in the following sample file.
Since I want to set more blank space if it is hidden, I add \blank[5cm] when it 
is in the \enablemode[hideSolution].
It works well except the figures and bars are not hidden. Only texts, even  in 
the mp part, are hidden.
It is OK for me.

However, it would be much better to set the height of blank space depends on 
the height of hidden texts.
Is there a way to set the variable height  using “overlay” stuff instead of 
\blank[5cm]?

Thank for reading.

Best regards,

Dalyoung

Re: [NTG-context] question about vardef variables

[Jeong Dal]

Dear Damien Thiriet,

If you change ‘vardef’ to ‘def’, you will get the figure.
There is a difference between ‘vardef’ and ‘def’.
AFAIK, vardef returns the value of the last statement in the macro.
Please see  the examples in Metafun manual from page 32 ~ .
I hope that you find your answer there.

I am sorry that I am not good enough to explain the variables.

Re: [NTG-context] removing many lines about font in log.

Thank you for the explanation.
Since those messages takes too many lines in the log file, I ask about it.
I prefer to suppress them. But, someone want to see them.

Since there is no problem to compile, it is OK to let them shown for some one

Hi,

I tried to make a table using \dorecurse or \doloop as in the example.
There is no error but \recurselevel is not increased, all are 0 in the first 
example and only two rows are created with the \recurselevel 0 and 2 only in 
the second example.

Does the tabulate cause the error?
What is wrong in this MWE?

Thank you for reading.

Re: [NTG-context] Installing VSCode extension?

[Jeong Dal]

Dear Mikael,

> within vs code? As of
> now, I opened a terminal and compiled from that, but that feels like the
> wrong way of doing it.

For the first question, I don’t know either.
For the second question, I’d like to explain what I did for compiling TeX file 
in vscode.
Since I use vscode in MacOsX, you may find your way in Linux.

There is a tasks.json file in .vscode folder.
I added the following script in the “tasks":[ ]  and save it.
(You have to modify the  "texmf-osx-64/bin” path in the following script from 
your machine.

{
"label": "ConTeXt LuaMetaTeX",
"type": "shell",
"command": "export 
PATH=/Users/graph/ConTeXtLM/tex/texmf-osx-64/bin:$PATH;mtxrun --autogenerate 
--script context --autopdf --purge '${file}'",
"args": [],
"options": {
"cwd": "${fileDirname}"
},
"group": {
"kind": "build",
"isDefault": true
}
 },

When you want to compile a ConTeXt file, find “terminal > Run Build task” in 
the menu,
then “ConTeXt LuaMetaTex” will pop up.
Or just use the key “command-shift-B” instead using menu item.

I hope that it may help.

Re: [NTG-context] Installing VSCode extension?

[Jeong Dal]

Dear Alasdair McAndrew,

I am using vscode in iMac, so my setting may not work for you.



1. First, find files for vscode in your TeX folder.

In my case, 

/ConTeXt-homefolder/tex/texmf-context/context/data/vacode/extensions/context/*.*

2. In a homefolder, there is a hidden folder “.vacode”.

Copy context/*.* to  ./vscode/extensions/context/*.*

3. Open vscode and enable context-extension.

Since it was long time ago, my memory may not be correct.
However, I hope that it may give you an idea.

Best wishes,

Re: [NTG-context] Code lua in a table

[Jeong Dal]

Dear Fabrice,

You may split Binom(n,k) function into two functions as following:

*
\startluacode
P={}
combi = P

function P.fact (n)
  if n <= 0 then
return 1
  else
return n * P.fact(n-1)
  end
end

function P.ncr(n,r)
return P.fact(n)/(P.fact(r)*P.fact(n-r))
end
combi = {
fact = fact,
ncr = ncr,
}
\stopluacode
**

Your table is actually Pascal’d triangle. 
Using the above function, I was able to draw Pascal’s triangles.
Hans helped me to complete it.
I couldn’t wikify it at that time because I don’t know how to.  I’ll do it soon.

Here is the whole code for Pascal’s triangle in two different ways using Lua, 
Metafun and ConTeXt.
You may enhance the code.

\startbuffer[pt1]
numeric n,r,s,u,dx,dy,tt; u := 1.8cm;
path p, q;
pair A,B,start,now;
A := dir(210)*u;
B := dir(-30)*u;
dy := sind(30)*u;
dx := 2*cosd(30)*u;
for n=0 upto 4:
start := n*dir(210)*u;
for r=0 upto n:
s := n-r;
tt := lua("mp.print(P.ncr(" & decimal n & "," &  decimal r & " ))");
now := start+r*right*dx;
dotlabel.top(textext("$\displaystyle {" & decimal n & "\choose" & 
decimal r & "} = "& decimal tt & "$"),now);
draw (now+A) -- now -- (now+B);
endfor;
endfor;
\stopbuffer
\startbuffer[pt2]
numeric n,r,s,u,dx,dy,tt; u := 1cm;
path p, q;
pair A,B,start,now;
A := dir(210)*u;
B := dir(-30)*u;
dy := sind(30)*u;
dx := 2*cosd(30)*u;
for n=0 upto 8:
start := n*dir(210)*u;
for r=0 upto n:
s := n-r;
tt := lua("mp.print(P.ncr(" & decimal n & "," &  decimal r & " ))");

now := start+r*right*dx;
label(textext("$" & decimal tt & "$"),now);
endfor;
endfor;
\stopbuffer
\startluacode
P={}
combi = P

function P.fact (n)
  if n <= 0 then
return 1
  else
return n * P.fact(n-1)
  end
end

function P.ncr(n,r)
  return P.fact(n)/(P.fact(r)*P.fact(n-r))
end
combi = {
  fact = fact,
  ncr = ncr,
}
\stopluacode
\starttext

\processMPbuffer[pt1]
\blank[big]
\processMPbuffer[pt2]

\stoptext

I hope that it helps.

Dalyoung

[NTG-context] error during the installation of luametatex

[Jeong Dal]

Hi,

I tried to update luametatex which was running well(it was installed following 
the process in the wiki>installation> MacOsX catalina), but I got the following 
error after all the files are downloaded.

resolvers   > lua > loading file 
'/Users/graph/ConTeXtL/tex/texmf-context/tex/context/base/mkiv/math-spa.lua' 
succeeded

tex error   > tex error on line 2960 in file math-ini.mkxl: ! Undefined 
control sequence

l.2960 \normalsupmarkmode
   \plusone % 2 also disable ^[^+] in text mode




The control sequence at the end of the top line of your error message was never
\def'ed. You can just continue as I'll forget about whatever was undefined.

However, the installation continues to end. 
But the same error appears when I compile a tex file.

Re: [NTG-context] Vertical lines in matrices

[Jeong Dal]

Dear Weber Mattias,

Please see page 10 of “mathalign.pdf” made by Aditya.
He showed the way of writing  aligned math including  matrices.
For example,

\startformula

 \startmatrix[left={\left(\,},right={\,\right)}]

  \NC 1 \NC 0 \NC 0 \NR
  \NC 0 \NC 1 \NC 0 \NR
  \NC 0 \NC 0 \NC 1 \NR
\stopmatrix 
  \stopformula 
There are many other examples that you can use.

Re: [NTG-context] animation using \startuseMPgraphic

[Jeong Dal]

Dear Hans,

I have not experienced a bottleneck when running ConTeXt.
It is stable and fast. 

I am satisfied with ConTeXt except there are many features and commands which 
are not explained.
Frankly speaking, I don’t need that much commands for my job. 
Also it is not the problem because there are many experts who willingly give 
the solutions in the list mail

I appreciate you and your team.

Best regards,

Dalyoung

Re: [NTG-context] animation using \startuseMPgraphic

Dear Hans,

Of course, it runs so fast that it is meaningless to shorten the runtime.
It is my old habit to check the algorithmic efficiency.

It is just my interest.

Re: [NTG-context] animation using \startuseMPgraphic

[Jeong Dal]

Dear Wolfgang,

I’d like to ask you one more.

To make an animation, almost same graphics are drawn repeatedly.
In my code, for example,
The base figure(two circles, line, boundingbox) is fixed and only points are 
moved.
But it draws the base figure every time and it is not inefficient.

Is there a way to draw the base figure once, and draw the points only at each 
frame?

Thank you.
Best regards,

Dalyoung

Dear Hans,

Thank you for your nice code.
lua.MP.Whatever is something!

[NTG-context] running lua in metafun and in ConTeXt

[Jeong Dal]

Dear all,

I draw Pascal’s triangle with the label of each point created by using lua 
functions.
As you see in the code below, I defined fact(n) and combi(n,r) using lua.
For the calculation tt, I used two different methods.
Both are working well when I run the given code.

But I got an error, when I added this code to a ConTeXt file composed product 
and components,
and using the second method, i.e. combi(n,r). The first method is still working 
well.
The error message is as following:

metapost log> loading metafun, including plain.mp version 1.004 for metafun 
iv and xl
metapost log> 
luatex warning  > mplib: run script: [string "return mp.print(combi(0,0 ))"]:1: 
attempt to call a nil value (global 'combi')

metapost log> >> tt
metapost log> >> vacuous
metapost log> ! Equation cannot be performed (numeric=vacuous).

metapost log>   ; ENDFOR
metapost log> <*> ...now+A); draw now -- (now+B); endfor; endfor
metapost log>   ;;

I don’t know why the same code treated differently.
I think that I have to do something more in luacode which I don’t know.
Comments are wellcome!

Best regards,

Dalyoung

Re: [NTG-context] write a subtitle under the title of a chapter using outlined font

[Jeong Dal]

Dear Hans,

Your method perfectly works!
The number of chapter use the same font as the main title font and there is no 
big space between main title and the subtitle.

Thank you.

It allows to write it in two lines. However, the title is surrounded by ‘ “ ‘.
How to remove it?

[NTG-context] write a subtitle under the title of a chapter using outlined font

Hi,

long time ago, I can use outlined fonts for the title of a chapter by the help 
of the experts in this list.
Now, I’d like to write a subtitle under the title, but \crlf is not working.
I tried in several ways, but I couldn’t make it.

How to write them in two lines?

Thanks.

When I use Atom for ConTeXt, I use the package,”process palette” in which 
commands and a key shortcut are defined. By pressing the defined key-shortcut, 
terminal will do the job as Hraban said.

Re: [NTG-context] background color of text in contour(former: ntg-context Digest, Vol 186, Issue 61)

Dear Hans,

I run the following code which is in page 24,25 luametafun.pdf.

1. adding \starttext and \stoptext, it works fine. No overlapping. 
Also, functionstyle = “math” is working nicely.

2. removing \starttext and \stoptext, then functionstyle =“math” invoked an 
error.

3. removing \starttext, \stoptext, and functionstyle=“math”, it worked. However 
the caption 
“x=[…]; y=[….]” is overlapped.

%\starttext
\startMPcode{doublefun} 
draw lmt_contour [
xmin = 0, xmax = 4*pi, xstep = .05,
ymin = -6, ymax = 6, ystep = .05,
levels = 7,
height = 5cm,
preamble = "local sin, cos = math.sin, math.cos",
function = "cos(x)+sin(y)",
%functionstyle = "math",
background = "bitmap",

Thank you so much.

Re: [NTG-context] background color of text in contour(former: ntg-context Digest, Vol 186, Issue 61)

[Jeong Dal]

Dear Hans,

Thank you for the fix.
Background color is OK now.

A new problem in the caption:
Since width of the figure is narrower than the width of the line 
"x = [0,12.555]; y = [-6,6];”,
“y  =“ is written over 12.555. 

Is there any option to suppress the caption x, y since there are numbers of x 
and y in the figure already?

Thank you.

Re: [NTG-context] ntg-context Digest, Vol 186, Issue 61

[Jeong Dal]

Dear Hans,

I read the “luametafun.pdf” and run the codes one by one.
It is a really nice to have those figures easily.

During the reading, I found that there is a difference between the figure in 
the manual and the output of my run.
I run the following code at page 24-25 in “luametafun.pdf”.

\startMPcode{doublefun} draw lmt_contour [
xmin = 0, xmax = 4*pi, xstep = .05,
ymin = -6, ymax = 6, ystep = .05,
levels =7,
height = 5cm,
preamble = "local sin, cos = math.sin, math.cos",
function = "cos(x) + cos(y)"
background = "bitmap",
foreground = "edge", 
linewidth = 1/2, 
cache = true,
]; 
\stopMPcode

Re: [NTG-context] math align broken

[Jeong Dal]

Dear Hans,

I reinstall a new beta and test the previous file.
(LuaMetaTeX: version 2.03.4, ConTeXt version: 2019.12.16 18:54, format: 
2019.12.17)

The problem is gone!
The space in the aligned display math mode is normal.

Thank you so much.

Best regards,

Dalyoung

Dear Hans, 

Here is a small example which shows a strange spacing in the aligned display 
math mode.
The same code is OK in both inline mode and just display mode, but it is not 
good in aligned mode.

I hope that it helps your fix .

Thank you.

Best regards,

Dalyoung

Re: [NTG-context] math align broken

Dear Mikael,

I also confirm your problem. 
I am using
"ConTeXt  ver: 2019.12.06 21:40 MKIV beta  fmt: 2019.12.9  int: english/english”

However, if you change “\Bigl(“ to “\left(“, then the space between left 
parenthesis and text become narrower. 

I hope that it will be fixed soon.

Best regards,

Dalyoung
