Re: [NTG-context] Registers and getparameters

[Otared Kavian]

Hi Wolfgang,

Thank you very much for your reply and your wise advice to use the \setvariable 
mechanism. It is indeed much more convenient to use for what I intend to do.

The only remaining problem is that when several talks are included in my file 
(in the following example there three of them), then the entries to the 
register are correct but the associated pagenumbers are incorrect and are given 
the last pagenumber: in the following example all three talks are given the 
pagenumber 4 in the register. Is there something I am doing wrong?

Thanks agin for your time and attention: Otared K.

[NTG-context] Registers and getparameters

[Otared Kavian]

Hi all,

I have a list of speakers (and abstracts of their talk) in a rather long 
document, and the name of each speaker is written to a register named speakers. 
Then with the command \getparameters[Talk] I get the name of each speaker and 
try to write it to the register with

\speakers{\TalkSpeakerName}

Indeed this does not work to obtain the result I am looking for: the sorting is 
indeed under the letter « t », and most importantly the register gets only the 
last name in the list instead of getting each speaker name.

The following is a (not so minimal…) example. Can anyone help me in this matter?
Thanks in advance for your attention and time!
Best regards: OK

Re: [NTG-context] Problem with \definemathmatrix

[Otared Kavian]

Hi Aditya,

Thanks for sharing this nice module, it is really useful, especially when 
making documents for students while using Matlab or Scilab.

There is also in the distribution the module m-matrix.mkiv written by Hans and 
Jeong Dalyoung, which allows to manipulate matrices. 
Maybe one should add the functionality of your module to the one in the 
distribution and somehow unify their environments.

Best regards: OK

Re: [NTG-context] Problem with \definemathmatrix

Hi Fabrice,

I think the problem comes from a blank line in your matrix (after your last 
line of entries in your matrix). The following works fine for me:

\starttext

\startformula
A = \startpmatrix

Hi Bernard,

Transposing your table to an example given by Wolfgang Schuster some time ago I 
obtain the correct behavior, but I don’t know where the problem in your example 
comes from…

Please see whether the following gives what you want and comapre with the PDF I 
get here with ConTeXt  version 2018.01.14 15:55.

Best regards: OK

\startplacefigure[reference=fig:cow,title=A dutch cow]
 \externalfigure[cow]
\stopplacefigure

\placefigure[here][photo]{This is a cow}{\externalfigure[cow][width=2in]}

Take a look at \at{table}[tab:1] below.

Many thanks for your quick answer.
I just did change 
\ifnum\luatexversion<106
into
\ifnum\luatexversion<105

and rebuilt the formats: everything works fine as far as I am concerned…

[NTG-context] Context version 2018.01.04 17:37 does not produce output…

[Otared Kavian]

Hi Hans,

I wish you and all the community a happy new year.

I wanted to report a problem with yesterday’s beta release, version 2018.01.04 
17:37, which is that no PDF ouput is produced when a file is typeset:

% begin test.tex
\starttext
Hello
\stoptext
%end test.tex

When issuing the command
context —make —all
the log file says :
Your luatex binary is too old, you need at least version 1.06! 

Indeed the version of Luatex in the standalone tree is version 1.05.

Re: [NTG-context] synctex and TeXShop problem

[Otared Kavian]

Thanks Luigi for the link, but unfortunately the version 3.89 of TeXShop does 
not work for me (even with the magic line 
%!TEX useOldSyncParser
put at the begining of the source file), while version 3.77 does the sync stuff 
as expected, even by opening an \input source file.

I have put here


https://www.dropbox.com/sh/68gfmzci1g67y5d/AABxdQ9sZsCiR9k6se_4zX0ga?dl=0

example files which can be tested with various versions of TeXShop. I don’t 
have versions between 3.78 and 3.87, but my experience shows that the syncing 
works between the resulting PDF file of a source file typeset with ConTeXt 
version 2017.11.15 22:08 and TeXShop version 3.77, while the syncing does not 
work with versions 3.88 and 3.89.

Best regards: OK

Re: [NTG-context] synctex and TeXShop problem

[Otared Kavian]

Hi Alan,

A few weeks ago Steffen Wolfrum and myself reported the issue to Richard Koch 
who did some research and discovered the origin of the problem. He has written 
again the part of the code related to synctex and ConTeXt and will issue a new 
version where the problem is fixed.

In the meanwhile you can use a previous version of TeXShop (I use version 77 
and I can send you a Dropbox link to download it, of you wish) where the 
syncing between the PDF result and the ConTeXt source works fine.

Best regards: OK

Re: [NTG-context] Problem with math alignment

[Otared Kavian]

Dear Dalyoung,

Thank you for having tested my example.

Regarding what you are reporting in another thread about the weird behaviour of 
\overline in columns, I was traveling and could not test your file. Now I 
tested your example and I get the same result as you with the latest beta 
2017.11.08 22:45.
The strange fact is that if one puts 
\startitem $\overline{A} = A$ \stopitem
as the first item in your example (instead of the second), then ConTeXt creates 
three columns, with the first item the result of the above line, and then items 
2 and 3 in the second column and finally item 4 in the third column. Despite 
this the textwidth is divided into four…

I hope Hans will see your message and fix the issue.

Best regards: OK

Re: [NTG-context] Problem with math alignment

[Otared Kavian]

Hi Matthias,

Thanks for your answer. I think that Hans has changed the way entries of 
mathmatrix are handled, that is they are now centered and this cannot be 
changed…
However I think now that my way of using mathmatrix in order to get aligned 
cases, should be changed into the following:

\definemathalignment[alignedcases]
[n=3,
align={right,left,left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]

Once this is done, the result is as expected since the math alignment 
environment accepts changing the alignment in each column. However the big 
problem is that one loses the left brace encompassing the displayed equations… 

I hope Hans will read this and help fix the issue…

Best regards: OK

[NTG-context] Problem with math alignment

[Otared Kavian]

Hi everybody,

Does anyone have noticed that the mathalignment has changed its behaviour 
recently? I think a bug has managed to enter the environment which handles the 
mathalignment, at least since a few weeks ago. I did not report it earlier 
because I was traveling and did not have a stable internet access.

Here is a minimal example where on can see in the first displayed formula that 
the first and third column are centered while the first one shoud be 
right-aligned and the third one left-aligned. (Actually it seems that all 
columns are centered…)
%%% begin pb-math-align.tex
\definemathmatrix[alignedcases]

Re: [NTG-context] Arbitrary tag of displayed formula

Hi Mikael,

I learned the following from Aditya some time ago, on his website Random 
Determinism: maybe you can adapt it to your needs.

\defineconversion[myset][\star,{\star\star},{\star\star\star}]
\defineformula[star][numberconversion=myset]

\starttext

\startstarformula
a^4 + b^4 = c^4.

Re: [NTG-context] size of footnote numbers

[Otared Kavian]

Hi Hraban,

If you want to change the way the footnote number in the text is shown 
something like a variation of the following might help you (copying this from a 
solution given by Wolfgang S. a few years ago…):

\define[1]\MyFootnotenoteCommand{\high{\bf{(#1)}}}
\setupnote[textcommand=\MyFootnotenoteCommand]
\setupnotation[footnote][left={(},right={)}]


\starttext
Hi there!\footnote{I’m a footnote.}

Re: [NTG-context] synctex, TeXShop and \input files

[Otared Kavian]

Hi Hans,

Thanks for the hint. Indeed every input file has got a reference in synctex 
file produced by ConTeXt. 
(I noticed also that during the typesetting ConTeXt creates another file with a 
suffix syncctx which is wiped out at the end of the processinng).

On the other hand after reading your hint I tried the same files with another 
application, TeXWorks, and there the syncing works perfectly. 
Therefore it seems that this is a problem with TeXShop and I am going to report 
a bug with Richard Koch.

Best regards: OK

Sure, but my problem is that I have a document with five or six chapters. Each 
chapter is included in files which are named for instance
chapter-1.tex
chapter-2.tex
and so on.  Then my file main.tex contains the lines 
\input chapter-1.tex
\input chapter-2.tex
and so on, in order to typeset the whole document. But now I don’t know how to 
sync the PDF file with the source files chapter-1.tex, chapter-2.tex, etc., in 
order to correct mistakes or mistypings when I discover them in the PDF file.
Clearly, the main file and these files are residing in the same directory.

Is there a way to tell context to look into the directory where the main file 
and my chapter files are?

Thanks a lot for your attention.

[NTG-context] synctex, TeXShop and \input files

[Otared Kavian]

Hi all,

Some time ago Hans added a new synctex command which seemed to work quite well: 
on a Mac running MacOS and TeXShop I could for instance click on a sentence in 
the PDF file produced by ConTeXt and the sentence was highlighted in the source 
file, even it were part of an \input file. For instance after typesetting the 
file:

%%% begin synctex-example.tex
\setupsynctex[state=start,method=max]
\starttext
\input knuth.tex
\hairline
\input ward.tex
\stoptext
%%% end synctex-example.tex

I could click on the sentence « The separation of any of these » in the PDF 
file and the file knuth.tex was opened and those words highlighted.

In the recent versions of ConTeXt (the latest being ConTeXt  version 2017.09.25 
19:19 MKIV) this does not seem to work anymore. As a matter of fact even when 
the source file is not an \input file, the syncing between the PDF and the 
source does not work anymore.

So my questions are the following (the « or » below is a mathematical one…): 

1) Has the \setupsynctex command changed recently? 
2) Or am I having troubles with the latest version of TeXShop (version 3.88).
3) Or is there an issue with the MacOS I am using (version 10.13 Beta).

Thanks in advance for any kind of help.

[NTG-context] \definemathfence commands

[Otared Kavian]

Hi everyone,

With the command \definemathfence it is possible to define for instance the 
following command

\definemathfence[duality][angle][command=yes,factor=auto]

so that $\duality{T,\phi}$ results in $\langle T,\phi \rangle$ and the \langle 
and \rangle are appropriately scaled when necessary.
How can one create a command called \bracparenth in order to get a left bracket 
on the left and a right parenthesis on the right, that is

$\bracparenth{a,b} = [a,b)$

and so that when necessary it scales automatically.

Below is the example for \duality.

Thanks in advance: OK

%%% begin mathfence-example.tex
\definemathfence[duality][angle][command=yes,factor=auto]
\definemathfence[parenth][parenthesis][command=yes,factor=auto]

\starttext

The action of $T$ on a smooth function $\phi$ is denoted by 
\startformula
\duality{T,\phi}
\stopformula
while the scalar product of two functions $f$ and $g$ is denoted 
$\parenth{f|g}$.

Re: [NTG-context] mathalignment vs mathmatrix

[Otared Kavian]

Hi Henri,

I think your code has a problem: the first one is that the definition of \Up 
and \Down is not understood when I compile your example, and then you introduce 
an empty mathmatrix which creates a difficulty too.
Once I remove the definitions of \Up and \Dn  the code is typeset (ConTeXt  
ver: 2017.09.05 15:10 MKIV beta).
Can you please give a more detailed example where you see the problem?

Best regards: OK

[NTG-context] Dangerous bend sign in mkiv

[Otared Kavian]

Hi,

Is there a way to get the dangerous bend sign (which exists in the Donald 
Knuth’s manfnt) in mkiv?
The following (given by one of our gurus and dating back to sevral years) works 
fine in mkii, but I don’t know how to translate it in mkiv…

%%% begin dangerous-bend.tex
\loadmapfile [manfnt.map]
\definefontsynonym [bends] [manfnt]

\def\GetSym#1{\getglyph{bends}{\char#1}}

\startsymbolset [Dangerous Bends]
\definesymbol [dbend]   [\GetSym{127}]
\definesymbol [lhdbend] [\GetSym{126}]
\stopsymbolset

\setupsymbolset [Dangerous Bends]

\setupbodyfont[manfnt]

\starttext
\symbol{dbend}
\blank[big]

\symbol{lhdbend}
\stoptext
%%% end dangerous-bend.tex

Thanks in advance: OK

Re: [NTG-context] How to put a circle on top of a character

[Otared Kavian]

Hi Hans,

Regarding what you have added on line 1327 of math-stc.mkvi, that line should be

\definemathover[\v!symbol][interiorset]["2218]

(instead of "2217).

I added also a wiki page for mathstackers:

http://wiki.contextgarden.net/mathstackers

Re: [NTG-context] How to put a circle on top of a character

[Otared Kavian]

Hi Hans,

Thanks for your attention.
Indeed I understand that the stackers structures are for putting things such as 
a circle or a star on top of another character or constructs. 

In fact, in terms of readability, the result of your new command 
\interiorset{K} is better than that of \mathring{K}, but the « K » coming out 
with \interiorset is set in Roman, while it should be math italic (or whatever 
font is used in math mode).
Also the white space around it is not yet correct. I’ll test what you will have 
added in the next beta and then put an entry on the wiki about mathstackers.

Thanks again: OK

Re: [NTG-context] How to put a circle on top of a character

[Otared Kavian]

Hi Hans,

That’s wonderful! Indeed this is very handy and I’ll add it to the wiki.

However, before doing so, I would like to ask how is it possible to get the 
command act entirely in math mode, that is respecting the distances and the 
math fonts. Please see the attached output. 

%%% begin interior-of-a-set.tex
\definemathstackers[symbol][voffset=-.30\mathexheight,hoffset=\zeropoint]
\definemathover[symbol][interiorset]["2218]
\starttext

Here is the new command \type{\interiorset{K}}: $\mathring{K} \neq 
\interiorset{K}$

\stoptext
%%% end interior-of-a-set.tex

Best regards: OK

Thanks Aditya,

Indeed the solution is already there in luatex-math.tex… 
one can just use $\mathring{A}$ out of the box!

I see why I love ConTeXt :-)

[NTG-context] How to put a circle on top of a character

[Otared Kavian]

Hi,

How can I put a small circle on top of a character in math mode (for the 
curious this is needed when one defines the interior of a set…).

I tried the following, but the small circle is too far away from the character 
A. I am sure I had an ugly solution for this in plain TeX some years ago but I 
woul dlike to have an elegant solution in ConTeXt.

%%% begin interior-of-a-set.tex
\showgrid
\starttext

\mathtriplet{A}{\circ}{}

\startformula
\mathtriplet{A}{\circ}{}
\stopformula

\stoptext
%%% end interior-of-a-set.tex

Thanks for your help: OK

Re: [NTG-context] About \setupheadertexts : simplify a code

[Otared Kavian]

Hi Aditya,

Thanks for having sent the example file: indeed with your file I can typeset 
the example and see the expected result.
I don’t know what happened when I copied and pasted the example from the e-mail…
I think the command
% macros = mkvi
was not set correctly written at the first line, that is I had a space before 
the percent sign « % ». In fact 
%macros=mkvi
or
%macros = mkvi
work as well.

By the way, wouldn’t be more user friendly, and more in the spirit of ConTeXt, 
if we had a command saying
\enablemode[mkvi]
in order to tell ConTeXt that we are using %macros = mkvi ?

Best regards: OK

Hi Aditya,

I tried to typeset your example, but got an error: whether or not the command

! Illegal parameter number in definition of \MyHeader

What am I missing here?

[NTG-context] Bug in startcombination

[Otared Kavian]

Hi Hans,

It seems that in the latest ConTeXt beta a bug shows up when using 
\startcombination, or something has changed recently that I have overlooked.
The following example typesets correctly in mkii, and used to produce a correct 
output with mkiv. However, now, with ConTeXt  version 2016.05.17 19:20,  the 
typesetting stops with an error message saying:

[………] Missing { inserted

 
{
 
\cr 
\pack_combinations_pickup_package_pair_c ->\cr 
   \pack_combinations_flush_capt...
l.20\stopcombination}
[………]

Here is the example:

%%% begin bug-combination.tex
\setupcolors[state=start]
\useMPlibrary[dum]

\starttext

This is our first picture.
\placefigure[none]{}{\externalfigure[dummy][width=6cm]}
\blank

This is a combination of 3 figures on two lines
\placefigure[none]{}
{
\midaligned{
\startcombination[1*2]
{\startcombination[2*1]
{\externalfigure[dummy][width=6cm]}{}
{\externalfigure[dummy][width=6cm]}{} 
\stopcombination}
{\externalfigure[dummy][width=6cm]}{}
\stopcombination}
}

\stoptext
%%% end bug-combination.tex

Re: [NTG-context] How can I add “page # of ##” on my document ?

[Otared Kavian]

Hi Fabrice,

The following gives the desired result, as Hans pointed ou:

\setuppagenumbering[alternative=]

\setupfootertexts[Page \pagenumber\ sur\ \lastpage][]

\starttext

\dorecurse{5}{\input knuth.tex \page}

\stoptext

Best regards: OK

Re: [NTG-context] mathradical defaults to "normal", should it perhaps be "default"?

[Otared Kavian]

Hi,

Indeed using \frac yields a weird result in the example sent by Mikael.
Compare the output of the three formulas below, with or without 
\setupmathradical[sqrt][alternative=default].

The results are correct using \over in both cases, while the first one is weird 
when using \frac and \setupmathradical[sqrt][alternative=default].

Re: [NTG-context] Position of prime for derivatives

[Otared Kavian]

Hi Mikael,

Indeed your observation is correct, but using \over instead of \frac yields the 
correct behavior. Please try the following sample:

%%% begin derivatives-prime-4.tex
\setupbodyfont[lucidaot]

\starttext

Compare the position of the prime sign in $f'/g$ in these two expressions: the 
first one using \type{{... \over ...}}
\startformula
\left({f \over g}\right)' = {f' \over g} - {f \over g^2}g'
\stopformula
(which yields a correct position of the prime for $f'$ in $f'/g$), and the 
second using \type{\frac{...}{...}}
\startformula
\left(\frac{f}{g} \right)' = \frac{f'}{g} - \frac{f}{g^2} g'
\stopformula
which yields a prime sign for $f'$ a little bit lower.

\stoptext
%%% end derivatives-prime-4.tex

Re: [NTG-context] Typescript/fallbacks problem

[Otared Kavian]

Hi Mohammad Hossein,

Your report is beyond my knowledge, but I would like to ask you a question 
about the setup of fallback fonts: why are you referring to « dejavudef » in 
the commands such as

 \definefontsynonym [SahelBd]   
[SahelBold][features={arabic,tlig},fallbacks=dejavudef]

while you have defined before « dejavudefault » (and not « dejavudef ») in:

\definefontfallback[dejavudefault][dejavusans] 
[range=generalpunctuation,check=yes,force=no]

Best regards: Otared K.

Re: [NTG-context] Position of prime for derivatives

[Otared Kavian]

Hi Mikael,

You are correct, the position of \prime depends on whether there is a next 
character or not after it, and it seems that this has an effect on its position 
for characters having a subscript as in
$f_{1}''(x) \neq f''_{1}(x)$ 
$f'f''f'’'$
Best regards: OK

Re: [NTG-context] Position of prime for derivatives

[Otared Kavian]

Hi Mikael,

I agree with what you are reporting: the current behavior of the \prime 
operator is not completely satisfying when using ConTeXt mkiv, while in mkii it 
is the most satisfying (in my opinion…). 

The turn around consisting in using $f^{‘’}$ or  $f^{\prime\prime}$, or even 
$f^{{}^{\prime\prime}}$, is not really satisfying either.

But I think (or I hope that) at some point Hans will fix it in mkiv.

[NTG-context] Position of prime for derivatives

[Otared Kavian]

Hi Hans,

Thanks for having fixed the behavior of the prime in the latest beta release 
(ConTeXt  version 2017.05.15 21:48).
However, as you may see in the two attached PDF files, the result is still 
incorrect when one types for example $f_2’’(x)$, which should give the same 
result as $f’’_2(x)$.
The correct behaviour is that obtained with mkii. Indeed one can circumvent the 
behaviour of the latest beta release of mkiv by using tricks such as the ones 
in the example code below, but this should be avoided in my opinion.

The following PDF have been obtained with mkii and mkiv with the following 
example code.
Best regards: OK

%%% begin derivatives-prime.tex
\starttext

\startformula
f''_{2}(x) = f_{2}''(x) = f^{''}_{2}(x) = f_{2}^{''}(x) % = f^{{}^{''}}_{2}(x)
\stopformula
As one may see the result of \type{f_{2}''(x) = } $f_{2}''(x)$ is not correct 
in \type{mkiv}. 

The following positions of the superscripts \type{(3)} are correct both in 
\type{mkii} and in \type{mkiv}.
\startformula
f^{(3)}_{2}(x) = f_{2}^{(3)}(x)
\stopformula

\stoptext
%%% end derivatives-prime.tex

Re: [NTG-context] mathdigits no longer works

[Otared Kavian]

Dear Mohammad Hossein,

The small modification I was talking about has nothing to do with the 
definition of fonts. In any case here is the file I used to typeset your 
example (I think you had \startttext instead of \starttext, and also you used 
\switchtobodyfont instead of \setupbodyfont: however I am not sure whether this 
is important or not) :

 begin

\definefontfamily [minionmath] [rm] [Minion Pro]
\definefallbackfamily [minionmath] [mm] [dejavusansmono] 
[range=digitsextendedarabicindic,offset=digitsnormal]
\definefallbackfamily [minionmath] [mm] [dejavusansmono] 
[range=digitsextendedarabicindic,offset=digitsbold,tf=style:bold]
\definefontfamily [minionmath] [mm] [TeX Gyre Pagella Math]

%\switchtobodyfont[minionmath]
\setupbodyfont[minionmath]
\starttext

\startformula
{\tf xyz} xyz {\bf xyz} {\bi xyz}, 
\stopformula

\startformula
2+3+4+5+6+7+8+9+10 = {\bf 2+3+4+5+6+7+8+9+10}
\stopformula

\stoptext

 end

Re: [NTG-context] mathdigits no longer works

[Otared Kavian]

Hi Mohammad Hossein,

I don’t get what you expected to obtain in your message, but typesetting your 
example code (with a small modification) I get the attached PDF file, which 
seems correct to me.
I am using ConTeXt  version 2017.05.12 22:40 MKIV beta, with LuaTeX version 
1.0.4 on MacOS 10.12.5.

Best regards: Otared K.

Re: [NTG-context] eqalignno failing

[Otared Kavian]

Hi Hans,

Since a few weeks (or months?…) ago the use of \eqno and \eqalignno has been 
changed in mkiv. 
It is better to use the construction such as:

\placeformula
\startformula
\startalign
\NC H(I,J) \NC = H(I) + H(J|I) \NR[eq:equivoc]
\NC W(I,J) \NC = H(J) - H(J|I) \NR[eq:wedinfo]
\stopalign
\stopformula

Best regards: OK

Thanks Hans for your quick reply! 
I guess the file type-imp-lucida-opentype.mkiv is there to take care of 
everything when using the font: so once I have the fonts, and ConTeXt knows 
where they are,
can I use them just by saying
\setupbodyfont[lucida]
or are there other commands to issue?

Many thanks for your precious help: OK

[NTG-context] A question about Lucida fonts

[Otared Kavian]

Hi,

I would like to buy the set of Lucida fonts from TUG
https://www.tug.org/store/lucida/index.html 

but I am wondering which flavor, Open Type or Type 1, is supposed to work 
smoothly (and easily…) with ConTeXt mkiv. Actually a very long time ago I 
bought those fonts from yandy.com , but those were designed 
to work only on a Mac OS 9 (yes I am so that old… :-).

Since I am sure some people on the mailing list have an experience and good 
advices to share, I would appreciate having their opinion.

Hi Aditya,

That is a good point: if the equation numbers are on the right, there would be 
an ugly effect with the closesympbol near the number, but not if the equation 
numbers are on the left.

Personnaly I avoid finishing a displayed formula with a closymbol (since one 
uses sometimes the square for the D’Alembertien operator), but sometimes it it 
comes handy to have the possibility to add such a closesymbol.

I don’t know what has changed in recent ConTeXt mkiv which makes the solution 
cooked up by Wolfgang to not work anymore.

Unfortnately the same file typeset with the latest beta, and even with the

Re: [NTG-context] How to use tex.print in ctxlua

[Otared Kavian]

Hi Wolfgang,

Thanks for letting me know the command string.formatters[….]. It allows to 
avoid the concatenation, which is to avoid as Thomas points out.

Now that I have solved the issue with the spurious space, I have one more 
question: how could one print the values (vecteuX[i],vecteurY[i]) in a 
tabulated environment so that when for instance one has 15 such values, one 
gets 3 lines with 5 values on each line?

Best regards: OK

Re: [NTG-context] How to use tex.print in ctxlua

[Otared Kavian]

Hi Aditya,

Thanks, as Thomas, Pablo and you mentioned the right way is to use context() 
instead of tex.print()
Actually I just saw that one can also concatenate with context() as in:

context("(" .. vecteurX[i] .. ", " .. vecteurY[i] .. ")\\par")

which is equivalent to
tex.print("(" .. vecteurX[i] .. ", " .. vecteurY[i] .. ")\\par")

Re: [NTG-context] How to use tex.print in ctxlua

[Otared Kavian]

Hi Pablo,

Thanks for your answer: actually I did not know that it is possible to 
concatenate so easily in lua… Your solution is indeed simpler than what I did 
and solves also the problem of the spurious space before the closing 
parenthesis.

Best regards: OK

Hi Thomas,

Thanks for your answer.
Indeed I did not know that I could use directly 
context(vecteurY[i])
Now this solves my problem!

[NTG-context] How to use tex.print in ctxlua

[Otared Kavian]

Hi,

I would like to print in a text the values of a array computed in a  
\startluacode …. \stopluacode combination.
How can I do it properly? Please have a look at the example below and its 
output, which is not satisfactory because the right parenthesis is separated 
from the number by a space. How can I suppress this unwanted space? 
For instance I get (1, 103 ) instead of (1, 103).

Thanks in advance for any help,
Best regards: OK

Re: [NTG-context] Manually scaling math fences

[Otared Kavian]

Hi Aditya,

I agree totally with you and support your suggestion…
Maybe instead of the « delimiter » keyword, one could introduce a keyword such 
as « size »:


\MEAN[size=auto] expands to \left\langle .. \right\langle
\MEAN[size=] expands to \langle .. \rangle
\MEAN[size=big]  expands to \big\langle  ... \big\rangle
\MEAN[size=Big]  expands to \Big\langle  ... \Big\rangle
\MEAN[size=bigg] expands to \bigg\langle ... \bigg\rangle
\MEAN[size=Bigg] expands to \Bigg\langle ... \Bigg\rangle

Hi Floris,Since you specify	align=leftin the setup of your description, I don’t see why the output would be unexpected.

Re: [NTG-context] which command would give the same effect as \pause in beamer ?

Hi,

If you use mkii you can still use RawSteps, but in mkiv it does not work 
properly and should be rewritten. 
However, as Hans indicates, one can use \startsetp and friends, as shown in the 
example presentations found in your directory

Re: [NTG-context] issue with linenotes and luatex-1.0.3

[Otared Kavian]

Dear Pablo,

For your information, I tested your file hefes.tex, and the only pages without 
the issue are pages 3 and 5, with LuaTeX, Version 1.0.3 and ConTeXt  version 
2017.02.23 18:37 (I am running MacOS 10.12).

However with LuaTeX, Version 0.95.0 and ConTeXt  version 2016.05.17 19:20 (from 
TeXLive 2016), the result is as expected.

Re: [NTG-context] LineSpacing Issue in Arabic Fonts

[Otared Kavian]

Hello Ibn Saeed,

I tried your example file and obtained the same result as you with 
LuaTeX Version 1.0.3 and the latest beta version 2017.02.19 17:14.

However the result is as expected with the version from TeXLIve, that is 
LuaTeX Version 0.95.0 (TeX Live 2016) and ConTeXt  ver: 2016.05.17 
19:20.

So there seems that, as Hans warned us a few days ago, there are still some 
problems with LuaTeX and the latest version of ConTeXt.

Best regards: OK

Re: [NTG-context] Dot fills shifted down

[Otared Kavian]

Hi Lukas,

Maybe you can use

symbol=\lower.25em\hbox{.},

instead of what you set in your \definefiller definition is what you need?

Re: [NTG-context] Basic question

[Otared Kavian]

Hi John,

If you have updated your ConTeXt tree, you should issue the following command 
(only once…)

texexec --make —all

in order to create again the mkii format. Then you can say

texexec myfile.tex

in order to typeset the file myfile.tex

Re: [NTG-context] Title without the parentheses

Hi Fabrice,

In order to have the box aligned with the text, it is enough to use the  \lower 
command as in the exmaple below.
Best regards: Otared K.

Re: [NTG-context] Title without the parentheses

[Otared Kavian]

Hi Fabrice,

Below you have an example which may help you to achieve what you want, but in 
the example I am sending there is an issue with the alignment of the title.
I could not solve the issue, sorry…

Best regards: Otared K.

\startuniqueMPgraphic{MyShape}
path p ; 
p := unitsquare xscaled \overlaywidth yscaled \overlayheight ;
pickup pencircle scaled \overlaylinewidth ;
fill p withcolor \MPcolor{\overlaycolor} ;
draw p withcolor \MPcolor{\overlaylinecolor} ;
\stopuniqueMPgraphic

\defineoverlay[MyBackgroundLayer][\uniqueMPgraphic{MyShape}]

\define[1]\MyExoCommand{%
\startframed
[background=MyBackgroundLayer,
frame=off,
width=3cm,
backgroundcolor=darkred]
{\white Exercice #1}
\stopframed
}
\defineenumeration[ex]

Re: [NTG-context] Title without the parentheses

[Otared Kavian]

Hi Fabrice,

To suppress the parentheses in the title, you can use the keys titleleft and 
titleright as in the following:

\defineenumeration
  [ex]
  [text=Exercice,
   title=yes,
   titleleft=,
   titleright=,
   width=fit,
   numberconversionset=ACCONVERSION,
   alternative=top,
   number=yes]

In order to put the word « Exercice » in the frame you should define a special 
command, for instance \MyTextCommand and the say text = \MyTextCommand

Oh yes… sorry, I am ashamed :-(
I just put the code sent by Hans below your’s, and then commented out your 
code, including the definition of layers and backgounds…

Indeed everything works as expected with a buffer.

Hi Hans,

Unfortunately your workaround with \getbuffer does not produce the correct 
page: it gives only a blank page.

Re: [NTG-context] dorecurse problem

[Otared Kavian]

Hi Rik,

I can confirm the behaviour you are reporting (even without 
\startstandardmakeup—\stopstandardmakeup, but adding a line of text in the 
document in order to have an output).
It seems that \dorecurse suppresses the passage to another line, since if one 
says \dorecurse{10} the texts in the framed layer are typeset ten times on the 
same line, as if the command \startlines were not there.

Re: [NTG-context] Vertical space around displayed formulas

[Otared Kavian]

Hi Hans,

Thanks for your attention which fixed most of the difficulties with vertical 
distances around math formulas.
However, after typesetting a long document, I noticed that there are still some 
incorrect behaviours. The following minimal example, extracted from that long 
document, shows what is wrong: please have a look at the second formula in the 
attached PDF. (The output with the older version from TeXLIve 2016 is correct).

%% begin vertical-space-bug.tex
\starttext

\input knuth.tex
\startformula
a \leq a_{n+1} \leq a_{n} \leq b_{n+1} \leq b_{n} \leq b, \qquad\mbox{et}\qquad 
0 \leq b_{n} - a_{n} \leq 2^{-n}(b_{0} - a_{0}).
\stopformula
\input ward.tex
\startformula
g(x_{*}) = \lim_{n\to\infty} g(a_{n}) \leq 0 \leq \lim_{n\to\infty} g(b_{n}) = 
g(x_{*}),
\stopformula
\input knuth.tex

\stoptext
%% end vertical-space-bug.tex

Re: [NTG-context] Vertical space around displayed formulas

[Otared Kavian]

Hi Nicola,

In fact, if you are in a hurry and don’t use subtle things introduced since May 
2016, you can use the stable version of ConTeXt from TeXLive 2016 (the bug 
noticed by Mikael, and you, is absent from that version of ConTeXt).

Hi Nicola,

Indeed there is a recent bug, reported by Mikael Sundqvist a few days ago, and 
Hans is aware of this. 
Hans said in the next release of ConTeXt beta the issue will be fixed.

Re: [NTG-context] Displayed formula inside paragraph change vertical space before the paragraph

[Otared Kavian]

Hi Mikael,

Thanks for making it clear to me: I was looking for the changes in vertical 
spacing around the formula… Now it is clear that there is a bug in the vertical 
spacing: when I typeset your example with mkii or mkiv ConTeXt Version 
2016.05.17 from TeXLive, the issue is not present, as one may see from the 
attached output.

Maybe you should open a new thread with a title like « Bug in vertical spacing 
of paragraphs » so that Hans may see it more easily.

Best regards: OK

Hi Mikael,

I tested your example but I see no difference in the outputs, with, or without

I am using ConteXt 2016.12.28 17:55 MKIV beta.

[Otared Kavian]

Hi Wolfgang,

Thanks for your remark: indeed after issuing the command

mtxrun --script cache --fonts —erase

the result is correct with palatino as the choice of font. 
I notice that the luatex-cache increases during the time: is there any reason 
for which the luatex-cache is not erased when updating? 

Best regards: OK

Re: [NTG-context] Strange spurious character

[Otared Kavian]

Hi Hans,

Indeed with your solution, that is saying

\definefallbackfamily[mainface][serif][texgyrepagella]
\definefontfamily[mainface][sans][texgyrepagella]
\setupbodyfont[mainface]

or more simply saying

\setupbodyfont[palatino,12pt]

there is no problem. It seems that the issue comes from the use of

\definefontfamily[mainface][sans][palatino]

in the example I sent.
So I am going to use your way of defining the fontfamily.

Thanks again and best regards: OK

Re: [NTG-context] Strange spurious character

[Otared Kavian]

Hi Hans,

Thanks for the quick fix.
Indeed the spurious character does not show up anymore, but in the minimal 
example below the default body font seems to be set to bold italic, please see 
the attached PDF (I did not observe this in my real documents, but curiously it 
shows up in this minimal example): it may be that I am using a wrong font 
definition here. 
The version of ConTeXt is  2016.11.18 22:20 MKIV beta  fmt: 2016.11.18.

 begin bug-beta.tex
\definefallbackfamily[mainface][serif][palatino]
\definefontfamily[mainface][sans][palatino] 
\setupbodyfont[mainface]

\starttext

Why is the text in bold italic?

\stoptext
 end bug-beta.tex

Best regards: OK

[NTG-context] Strange spurious character

[Otared Kavian]

Hi Hans,

After having updated my installation of ConTeXt, I noticed the presence of a 
spurious « ß » character at the top of every document, or sometimes in the 
footer, or in the header.
Also in the example below the text is typeset with bold italic, even though 
there is no request for it.

Here is a minimal example:
 begin bug-beta.tex
\definefallbackfamily[mainface][serif][palatino]
\definefontfamily[mainface][sans][palatino] 
\setupbodyfont[mainface]

\starttext

Why is there a « ß » LATIN SMALL LETTER SHARP S  above?

Why is the text in bold italic?

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Dalyoung,

Yes I see what your problem might had been. Recently ConTeXt creates a fine 
named FILENAME.tuc when one typesets FILENAME.tex. This *.tuc file creates 
difficulties when the typesetting is stopped for some reason or another, 
because then at times it is impossible to typeset again the same file even if 
the error has been fixed.

Maybe we have to ask Hans whether this behavior is intended or not: in any case 
one has to remove that *.tuc file manually in order to typeset again.

Best regards: OK

Re: [NTG-context] Clickable question/answer numbers (Otared Kavian)

[Otared Kavian]

Dear Dalyoung,

I guess you are typesetting the wrong file, or you have put the last code I 
sent into a file which contains something of the previous codes…
Indeed in the last file I sent (which I am sending again at the end of this 
reply) does not contain the command \myanswer… which appears in your error 
message.

Please test the code below and let me know if you encunter a problem.

Re: [NTG-context] Clickable question/answer numbers

Hi Wolfgang, Hi Mikael,

Thanks Wolfgang! I didn’t know that \beginBLOCKNAME \endBLOCKNAME cannot be 
used in other macros… There is some mystery in this for me.

Now with 
\doifnotmode{*trialtypesetting}
everything works as expected. 

Since I don’t know whether, nor where on the wiki, this can be wikified, for 
the archives and for other possible users, I copy below the entire example 
which allows to have interactive Questions and Answers. One can also easily add 
a chapter for Hints, if necessary.

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Wolfgang,

Thanks for the solution you sent yesterday.
Your solutions solves the problem I was fighting with, but when I try to apply 
it to my real document there is an issue when some questions don’t have 
answers. This prevents the synchronization of Questions and Answers if one 
doesn't issue the commands
 
\beginanswer
\incrementcounter[answer]
\endanswer

right after a question without an answer. And when the above commands are 
issued, the last Question does not show the link to its corresponding Answer.

Below is your modified example where one can see the problem (please see the 
fifth Question in the source below).

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Wolfgang, Hi Mikael,

Thank you both for your great inputs!

I tried to modify the code each of you sent yesterday in order to « couple » 
automatically each question with its answer, using the keyword « coupling=… », 
but somehow I am unable to create automatic references by extracting the number 
of each question or that of each answer, for example by using \rawcountervalue,
or \currentconstructionnumber. Strangely the latter gives the name of the 
construction and not a number: is it on purpose?

The solution Wolfgang proposes today, using the new keyword referenceprefix, is 
almost perfect: however would it possible to create a version of
« currentconstructionreference » which creates a reference named for instance
answer:NumberOfCurentConstruction

The reason for which I need such a construction is that in a document with 
hundreds or more exercise —> hint —> solution, it would be handy to avoid 
creating each time a manual reference, and then one would navigate from a 
Question to its Hint and then  back to the Question or go to its Answer.

Best regards: OK

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Mikael,

Thank you for sharing the solution you found!

Your definitions suit me too, but in any case I’ll play with your code to see 
whether using the concept of « coupling » between each exercise and its 
solution (or hint, if one adds them) could allow the creation of an automatic 
interaction link between them, so that one can remove the necessity of adding 
manually a reference to each exercise and each solution.

Best regards: OK

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Mikael,

A partial solution to the feature we are discussing is contained in the example 
below, but somone more aware of ConTeXtish coding might improve it.
It is not satisfactory in that one has to define twice \startquestion and 
\StartQuestion, \beginanswer and \BeginAnswer, and more importantly one cannot 
generate automatically the references (I tried \getnumber[question] and such to 
append to Q:\getnumber[question] for instance, but something does not work…).

Le me know if you find a satisfactory solution…

Best regards: OK

Re: [NTG-context] Clickable question/answer numbers

[Otared Kavian]

Hi Mikael,

I had a similar question some time ago, but I wanted to add a sort of automatic 
referencing of questions and answers (and interaction going from questions to 
answers and back). 

If you accept the hurdle of adding manual references, in your case you can add 
(for instance…)

\goto{:-)}[Q:test]

to the end of your answer to go back to the respective question. But when you 
have several dozens of such references to add manually, it is not a good idea.

However I could not find a way to code the items (that is the questions) in 
such a way that each adds automatically a unique reference, and so I am 
interested too in the solution of the problem you mention.

Best regards: OK

Re: [NTG-context] avoid newline after definestartstop

[Otared Kavian]

Hi Michael,

Maybe what Wolfgang meant by « putting the marks by hand » is something like: 
you define \StartCitation and \StopCitation in the following way:

% begin quotation-note.tex

\define\StartCitation{\startnarrower[left,right]«~}
\define[1]\StopCitation{~»\footnote{#1}\stopnarrower}

\starttext
\input tufte
\StartCitation
 \input knuth
\StopCitation{This is a Quote of Donald Knuth}
\stoptext
% end quotation-note.tex

Indeed instead of the quotation marks « and » you can put whatever you wish.
If you have quotations without footnotes, then you may define another 
start-stop.

Best regards: OK

Re: [NTG-context] Footnotes in footnotes

[Otared Kavian]

Hi Jose Luis,

Indeed the example you sent does not work as expected, but as far as I remember 
for nested footnotes one can use the following construction (I found this 
exmaple in my archives…):

 begin nested-footnotes.tex
\starttext

This\footnote{Or that\note[footB], if you prefer.}%
\footnotetext[footB]{Or possibly even the other\note[footC].}%
\footnotetext[footC]{It could be something entirely different.}
is a sentence with nested footnotes.

\stoptext
 end nested-footnotes.tex

Best regards: OK

look here:

\startlinenumbering

Hi Henri,

The error is indeed extremely bizarre, and maybe funny, but if you want just to 
find a temporary solution in order to finish your project, it seems that adding 
a special word (or maybe something else…) allows the typesetting of your file. 

I tried the following modification of your sample with ConTeXt  ver: 2016.05.17 
19:20 (and LuaTeX Version 0.95.0) from TeX Live 2016.
The file name is bizarre-error.tex (if there no hyphen in the file name 
everything is allright).
It compiles both with the latest beta in standalone ConTeXt, as well as with 
the stable one from TeXLive 2016.

It is important to have a blank line before the line containing «  
\phantom{Junior} ».
If I remove the line «  \phantom{Junior} » then the file does not compile with 
the version of ConTeXt from TeXLive… (but it does with the latest beta)
If I replace it with the word « Junior », again it compiles fine. 
However if I replace that line with «  \phantom{Bizarre} » or even the word « 
Bizarre », the file does not compile :-)
But if your replace it with « Bizarre \phantom{Junior} » or with « 
\phantom{Bizarre} \phantom{Junior} » it compiles again…

All this seems funny to me, but I understand that it might stress you!

Best regards: OK

Re: [NTG-context] Underlining formulas and units

[Otared Kavian]

Hi,

Maybe you should use rather

$\underbar{F_C=\unit{1e2 newton}}$ or \underbar{\unit{1e2 newton}}

since otherwise \underbar considers each character in the math formula as a 
word, which should be underlined separately.

Best regards: OK

Re: [NTG-context] Recommendations on presentations

[Otared Kavian]

Hi,

I use also MacOS and all my presentations are made with ConTeXt. The easiest 
thing to do is to take examples from simpleslides, or from the examples by Hans 
in the folder

tex/texmf-context/tex/context/modules/common

of the standalone tree, and then adapt them to your needs and your taste.

Best regards: OK

Re: [NTG-context] prevent indent after usage of defined itemgroup

[Otared Kavian]

Hi Mikael,

I didn’t know the difference between \noindent and \noindentation… It reminds 
me of the subtle difference between \quote and \quotation, but I cannot tell 
you why there is such a difference.

Regarding the issue with the integral sign being too close to the line of text, 
since you are using \displaystyle in an inline math formula, I think the 
easiest solution is to add \blank[big] at the lines where such issues appear, 
or to change the amout of \blank in the « after= » key by saying for instance

after={\blank[2*medium]\noindentation},

Best regards: OK

Re: [NTG-context] Columnset and footnotes

[Otared Kavian]

Hi,

Indeed it seems that there is a bug with \columnset. However the separation 
rule for the footnotes is shown if one uses \startcolumns, as can be seen with 
the following example.

Best regards: OK
%%% begin column-footnote.tex
\definecolumnset[n2][n=2,balance=yes]
\setupfootnotes[location=page]
\starttext
\startcolumnset[n2]
Footnote \footnote[foo]{This is a footnote.} \input linden
\stopcolumnset

\startcolumns[n=2,rule=on]

This is a footnote\footnote {\input ward}

Re: [NTG-context] Nested itemize horizontal/column problem

[Otared Kavian]

Hi Mikael,

The explanation and the solution given by Henri works fine here. The code below 
gives the attached PDF (with ConTeXt 2016.09.12 18:27 MKIV beta). The point is 
that an empty \item does not allow to begin a new level of itemization. 

Best regards: OK
%%% begin
\starttext
\startitemize[n]
\item \blank[-line]
\startitemize[a,horizontal,two]
\startitem First \stopitem

\startitem Fourth \stopitem
\stopitemize

Re: [NTG-context] Simpleslides presentation: list of topics

[Otared Kavian]

Hi Thomas,

A topic for me is just the title of a section (or chapter): in a presentation 
it happens that one has a few of them, and in my case certainly less than ten. 
It is useful to be able to go back to the list of these topics and jump to one 
of them. But you are right, usually a presentation is in principle linear.

Actually what I wanted to do was just to put a list of my topics on one page 
(and this can be done easily), and then what is lacking at the moment is a link 
to jump to that page from any other slide.
For the latter aspect, I think I can cook up a (non optimal) solution for now.

I understand that what I am looking for, may not be justified in most cases, 
and thus I do not at all suggest that you should modify anything in the 
simpleslides module… The idea of your module is to remain simple, and simple is 
beautiful!


Thanks again for your attention and your remarks.
Best regards: OK

I’ll have a look at the examples you are mentionning: thanks for sharing.

As I said in another message, for now I can use the simpleslides module, which

Re: [NTG-context] Simpleslides presentation: list of topics

[Otared Kavian]

Hi Aditya and Thomas,

Thanks to both of your for your attention to my bizarre request.
Actually it is quite easy to have a page a list of the topics on a page, as one 
can see in the following example (please see below). Tne only thing I am 
lacking write now, is a trick to go the list of topics from any page, without 
adding manually a link to that page on each slide.

Another question: I am not at all familiar with the code you have written for 
the nice visual counter used in simpleslides module. Would it be possible to 
add interactivity to each portion of that visual counter, in such that upon 
clicking on that portion one jumps to the corresponding page?
