Re: [NTG-context] \triangledown placed too low in Palatino
Hi,
The \triangle operator is used for instance in the « symmetric difference » of
two subsets: if $E$ is a set and $A \subset E$, and $B \susbet E$, then one
defines
\startformula
A \triangle B := (A \cup B) \setminus (A \cap B).
\stopformula
Then the mapping $(A,B) \mapsto A \triangle B$ is a commutative, associative
binary operator on the subsets of $E$.
Some people use instead $A \Delta B$, but this is not the traditional, nor the
correct way, to write this « symmetric difference » of two sets. This is why, I
guess, in TeX \triangle is an operator.
I have seen also \triangledown as an operator, but I don’t recall the context
in which it was used…
Regarding the notation \nabla to denote the gradient, and \Delta, to denote the
Laplace operator (which by the way can be defined as $\Delta u := \nabla \cdot
(\nabla u)$), Mikael Sundqvist gave the correct observations.
Best regards: OK

Jannik,
You are right. \nabla looks much nicer and is placed correctly. (I
still think the \triangledown placement is slightly off.)
My environment files from MkII days have \def\nabla{\triangledown}, so I
never tried the true \nabla until your suggestion.
In MkIV: \triangledown is mapped to 0x25BD while nabla is mapped to 0x2207.
These are different glyphs.
IIUC, the difference in placement is because \triangledown is defined as a
mathop (and hence centered on the math-axis) while \nabla is defined as a
mathord. Compare:
\startformula
\nabla T
\quad
\triangledown T
\quad
\mathop{\nabla} T
\stopformula
From what I remember, I was the one who added the mappings for triangledown
as a mathop based on, I believe, unicode-math package in LaTeX. I don't
understand what all the triangle operators are supposed to do. As such, I
cannot say whether the wrong placement is due to the wrong font metrics or
the wrong mapping (mathop vs mathord) by ConTeXt.

Re: [NTG-context] lower superscripts in MkIV -- too low?
Hi Sanjoy,
I agree with you to say that the position of subscripts and superscripts in
mkiv is not perfect: the same remark applies to the position of the derivative
sign « prime » as $u’(t)$.
Actually in mkii (and also in plain TeX) the positions of the superscripts in
your example are the same, but this is not the case with subscripts:
$x_{3}\ x\mathstrut_{3}$
that is in mkii the latter $x\mathstrut_{3}$ gives a lower subscript, while in
plain TeX both subscripts are positioned at an identical depth.
I would say the position of subscripts and superscripts in mkiv should be
identical with one gets with the latest beta (version 2014.03.20 16:59) in the
following example
\starttext
$x\mathstrut_{3}$ and $x\mathstrut^{3}$
\stoptext
However as Hans pointed out, regarding maths typesetting in mkiv there are also
some font related issues.
Best regards: OK
On 21 mars 2014, at 17:34, Sanjoy Mahajan san...@mit.edu wrote:
Dear math typesetting aficianados,
In the following example,

$x^3\ x\mathstrut^3$

the superscript without the strut is about 2pt lower than with the
strut, using MkIV. With MkII or plain TeX, they are the same height
(at the higher position obtained by using the \mathstrut in MkIV).
My eye tells me that the higher position looks more right. Do others
agree? Or, if it's a matter of taste, is the difference configurable
so that one can get the MkII behavior even without the \mathstrut?

One way is to increase the « degree of randomness » by saying

mycolor[2] := (0.6, 0.6, 0.4) ;
mycolor[3] := (0.5, 0.8, 0.5) ;
path p ;
p := unitsquare scaled 2cm ;
for i=1 upto 3:
fill p shifted (i*2.5cm, 0) withcolor transparent
(1,0.3,mycolor[round(uniformdeviate(10*i)/10)]) ;
endfor ;
\stopuniqueMPgraphic

Hi all,
I would like to have mp choose a (transparent) color randomly from a
predefined list. My naive approach was (let’s restrict it to three colors):
\startuniqueMPgraphic{colortest}
save mycolor ; color mycolor[] ;
mycolor[1] := (0.07, 0.21, 0.65) ;
mycolor[2] := (0.6, 0.6, 0.4) ;
mycolor[3] := (0.5, 0.8, 0.5) ;
path p ;
p := unitsquare scaled 2cm ;
for i=1 upto 3:
fill p shifted (i*2.5cm, 0) withcolor transparent
(1,0.3,mycolor[round(uniformdeviate(i))]) ;
endfor ;
\stopuniqueMPgraphic
\starttext
\uniqueMPgraphic{colortest}
\stoptext
Is there a better approach? The selection isn’t random enough for my taste
:-) Sometimes, in my real document, I get black color, even though black
isn’t in the list, so I suspect that mp doesn’t get a correct value for
mycolor[round(uniformdeviate(i))]. And finally: how could I define the colors
in a way that I could also use them outside of mp? Or do I have to copy-paste
the definitions into \definecolor’s?
All best

[NTG-context] [Math in ConTeXt]
Hi all, After a series of exchanges on the list, on the topic of how mathematics typesetting is and should be in ConTeXt, I am writing you this message to ask all those who use ConTeXt to typeset mathematics and who encounter various types of difficulties, or shortcomings, to send me their remarks, either on list or off list. I will check the problems with Aditya Mahajan and Mikael Sundqvist, and then submit feature requests or bug reports to Hans and Aditya who will try to fix the issues (I have asked these people about this, and they all agree…). In order to help me manage efficiently the task, please add the following tag [Math on ConTeXt] to the Subject field of your message. The issues which may be addressed are of the following categories: 1. Differences in the output of ConTeXt mkiv vs mkii (due to differences in engine) 2. Differences in the output of ConTeXt mkiv vs LuaLaTeX + Opentype math fonts (due to differences in macro package) 3. Differences in the output of ConTeXt mkiv vs PDFLaTeX + AMSMath (due to differences in expectation) 4. Bug reports (regarding commands of plain TeX missing in ConTeXt, the position of math accents, etc…) Indeed some of the issues may have their origin in the fonts (therefore not easy to fix thouroughly), but others may be fixed once the expectations are clearly expressed. As usual, please give minimal examples imbedded in \starttext ……… \stoptext so that we can test the issue you are reporting. Thanks for your attention and cooperation, Best regards: OK ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
Re: [NTG-context] OT: Reflections on usability ConTeXt for typesetting of mathematics
Hi, I do use ConTeXt for typesetting mathematics, and actually I began to use ConTeXt several years ago for my work as a mathematician: up to now I haven’t encountered a single instance in which ConTeXt would not give the expected result, and as a matter of fact the out-of-the-box capabilities and the quality of the typestting when using ConTeXt seems to me quite superior to plain TeX or LaTeX. I use ConTeXt for writing exercise sheets, lecture notes, and drafts of papers and all the presentations for my talks. It is true that when submitting my papers to journals, unfortunately I have to switch back to LaTeX, but even so I prefer using ConTeXt in all the preparation steps because it is more convenient to use, and also I can use these notes directly for my lecture notes and presentations. Now coming to answer your questions: I have a few questions: 0. Do you think that this is only a problem for beginners of ConText or it is a general problem of ConTeXt? All depends on how complex one's document is, and how deep one’s knowledge of TeX and ConTeXt is. 1. How many of ConTeXt users use this tool for typesetting of non-elementary mathematics? I cannot say anything about the overall number of users, but as I said above I use it for the kind of maths I am doing: some of it is really not elementary… 2. Are you satisfied with the results, which produces ConTeXt (thinking in the field of mathematics rate)? I am absolutely satisfied with the results. 3. What things do you need to have in ConTeXt study that one could bet mathematics at a reasonable level? My knowledge of TeX and ConTeXt is rather elementary, but this does not prevent me to use ConTeXt. Moreover in the rare situations in which I don’t know how to achieve a certain result, there a good group of gurus on the mailing list to help solve my problem. 4. Is ConTeXt able to substitute LaTeX to typesetting of math (e.g. in the future)? For sure it is: the reason for which ConTeXt is seldom used among mathematicians (or other scientists) is the fact that journals have developped specific macros for their layout and despite the fact that the quality and shortcomings of LaTeX are well-known, publishers of these journals are more than reluctant to switch to a more modern macro package of TeX, such as ConTeXt. 5. Can you think of any more questions that should be here? Maybe one can imagine a script which would downgrade a file written in ConTeXt to a LaTeX file, once one accepts to lose the quality of the typesetting… Best regards: OK On 9 févr. 2014, at 20:09, Jaroslav Hajtmar hajt...@gyza.cz wrote: Hello ConTeXist.

Re: [NTG-context] setuphead for in-paragraph head ?
Hi Jaroslav,
Actually the formatting of what you put in the block determined for example by
\beginanswer
The answer is…
\endanswer
is independent of the block mechanism: you can use whatever structure you want.
In the example we exchanged on, an enumeration such as
\startanswer
\stopanswer
where this \start \stop has been defined by \defineenumeration[answer], but you
can use your own compact formatting instead of this.

Re: [NTG-context] setuphead for in-paragraph head ?
Hi Wolfgang,
Thanks for the tip: I’ll try to adapt what you suggest to the case of blocks
and question-hint-answer, and then let you know if I succeed.
Out of curiosity, how can one access the counter associated to an enumeration
or an item?
Also, if I understand correctly, the command
\increment\QuestionCounter
creates first a counter named QuestionCounter, if it does not exist yet, and
then increments its value: so one does not need anymore commands such as
\newcounter\QuestionCounter
before incrementing it. Am I right?

Re: [NTG-context] setuphead for in-paragraph head ?
Hi Wolfgang,
Many thanks for your attention and insight.
With your code everything works as expected. In case others would be
interested, I give here a slight modification of what you sent, which works
very well with mkiv: I only added
\setupblock[question][before={\startquestion},after={\stopquestion}]
so that one can just say \beginquestion \endquestion without having to enter
each time \startquestion \stopquestion. I don’t know whether this is a good
idea or not, as it may have side effects…
I will put this example on the wiki, but before doing so I have another
question:
can one add two automatic links at the end of each question so that one can
navigate easily to the respective hint or answer corresponding to that
question? Indeed if this were possible, one would add also two automatic links
to each hint going to its question and the corresponding answer, and two other
links to each answer going to its hint and question. One can do this manually
by adding a reference to each question, each hint and each answer, but it would
be nice to have this done automatically.

Re: [NTG-context] setuphead for in-paragraph head ?
Hi Wolfgang,
In mkiv, even using \startanswer, \stopanswer (and the same syntax with
questions and hints) the blocks mechanism seems to be broken.
The error message is still the following:
\dostopnormalblock ...meter \c!after \par \egroup
argument ...fact that $2\times 5 = 10$. \dostopnormalblock
\dostartnormalblock {hint}...
\dodowithpar ...dler \v!construction \endcsname #1

When I understand a little bit more about that mechanism I’ll do other testings
and eventually ask Hans about what has been changed regarding blocks.
Best regards: OK

you have to finish the paragraph, e.g. by adding \par

I'm sorry it wasn't very clear. Now I understand that I misunderstood

Hi Wolfgang, Hi Aditya,
Thanks for your attention.
Unfortunately adding
\keepblocks[question]
the example I sent before does not work in mkiv, and changing
location=hanging
to
alternative=hanging
does not help neither…
The error message in mkiv is:
\dostopnormalblock ...meter \c!after \par \egroup

Re: [NTG-context] MacOsX Mavericks and Luatex
Hi everyone, I installed MacOS X 10.9 « Mavericks » on top of the latest MacOS X 10.8, and could run my installation of ConTeXt stand alone without any problem, despite having Skia.ttf on my system: Version 8.0d1e1 Location/Library/Fonts/Skia.ttf Unique name Skia Regular; 8.0d1e1; 2012-09-05 Copyright © 1993-2002 Apple Inc. Enabled Yes Duplicate No Copy protected No Glyph count 591 The rights for this font are: -rw-r--r-- 1 root wheel 480K 25 oct 04:56 Skia.ttf (these rights are the same as other fonts, and clearly I never changed these…). I also made anew the formats after having installed Mavericks, and did not notice any problem with a dozen tests I did. So it seems that the cases in which problems have shown up are quite various. The version of ConTeXt I have now is ConTeXt ver: 2013.10.15 13:52 MKIV beta fmt: 2013.10.25 (By the way, even after running first-setup.sh, I get always the same version… This may be due to the fact that I am in China right now?). A last word regarding the requests for changing the defaults for system fonts. The present situation has the advantage that people who are far from being geeks (for instance like me and the secretaries to whom I have shown how to use ConTeXt) can use whatever fonts they have on their system without tweaking the .cnf file, and without knowing how to write a typescript (thanks to the features added recently by Wolfgang). People who have the technical knowledge and don’t want to use their system fonts because of waste of typesetting time, can indeed change this default behaviour. So PLEASE don’t change the present default!

Re: [NTG-context] Conditional float references
Hi Marco,
Thanks for your answer: indeed I was wrong about the issue I reported about
doublesided page numbering. The reason is that I use TeXShop (on a Mac) and the
PDF produced is shown in a single page layout (it is however possible to have
doublesided layout as well: that's what I tested after your answer.
Also after applying your patch everything works as expected. I tested your file
with some maths formulas and changed even the language to French with:
\unprotect
\setuplabeltext
[\s!fr]
[\v!atpage=page\nobreakspace, %% “at page” sounds weird
\v!previouspage=à la page précédente,
\v!nextpage=à la page suivante]
\protect
\mainlanguage[fr]
without any problem. So your macro is just wonderful!
However maybe it would be better to have some setup options like:
\setuplabeltext[smartref][atpage={page},
previouspage={à la page précédente}, %or {page
précédente}
nextpage={à la page suivante}] %or {page suivante}
In case Hans is willing to add such capabilities to the cross referencing, it
would be great if one could setup the cross references in the same way by
saying for instance
\setupreferencing[alternative=smartref]
and then have \smartref be defined automatically.
A final remark concerns the possibility to visualize the reference points when
one is in the process of proof reading: at least in maths, it is usual to have
dozens of reference points to formulas, lemmas, theorems, etc, and it is quite
useful to be able to visualize such things. For instance I use a quick and
dirty macro to print in the margin « eq:Fermat » to the right of the following
formula
\placeformula[eq:Fermat]
\startformula
a,b,c \in {\Bbb N}^*, \quad n \geq 3, \quad a^n + b^n = c^n \imply abc = 0.
\stopformula
when I am preparing a paper. I do the same with references to lemmas and
theorems, but I print them in the margin to the left of the reference point.
For now, mkiv does not support such things and it's a pity.
Best regards: OK

Test 2 should give « See figure 1 and figure 3 on next page. »,
and Test 3 should result in « See figure 1 on previous page and
figure 3. »).
That's on purpose. If the graphic appears on the same double page,
it is visible and no further reference is printed. In traditional
typesetting a single page is rather insignificant. The reader is
always faced with double pages, never single pages.
Thanks again for sharing your module.
Well, it wasn't meant to be a module. I rather intended to start a
discussion and threw some code in to start with. If there's interest
I can make it a module.
Thanks for the feedback.

Re: [NTG-context] Conditional float references
Hi Marco,
Your macro is a wonderful help to have smart references: I have not yet tried
it with references to maths formulas, theorems, lemmas and such, but Iguess it
should work as well.
In order to help you nail down some small issues, here is how I used your
module: I put the file you sent
conditionalfloatreferences.mkvi
in a folder (i.e. a directory) and then in a TeX file I put the following (not
so) minimal example excerpted from your file
%%% begin smartref-test.tex
\usemodule[conditionalfloatreferences]
\useMPlibrary [dum]
%\setuppagenumbering [alternative=singlesided]
\setuppagenumbering [alternative=doublesided]
\starttext
{\bf Test 1:}
See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma].
\page
{\bf Test 2:}
See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma].
\startplacefigure [reference=fig:alpha] \externalfigure \stopplacefigure
\startplacefigure [reference=fig:beta] \externalfigure \stopplacefigure
\page
{\bf Test 3:}
See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma].
\startplacefigure [reference=fig:gamma] \externalfigure \stopplacefigure
\startplacefigure [reference=fig:delta] \externalfigure \stopplacefigure
\page
{\bf Test 4:}
See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma].
\page
{\bf Test 5:}
See \smartref{figure}[fig:alpha] and \smartref{figure}[fig:gamma].
\stoptext
%%% end smartref-test.tex
The issues I noticed are the following:
1. Typesetting the file gives an error message when there is no
\setuppagenumbering[alternative=doublesided]
Actually it typesets if one ignores the error message (but some issues like the
ones below remain).
2. In the above minimal example, when stating
\setuppagenumbering[alternative=doublesided]
then Test 2 and Test 3 do not result in the smart references expected (they
both result in « See figure 1 and figure 3. » while Test 2 should give « See
figure 1 and figure 3 on next page. », and Test 3 should result in « See figure
1 on previous page and figure 3. »).
Thanks again for sharing your module.

Hi,
a couple of times the question came up¹²³ how to create more
intelligent referencing. There are already mechanisms in the core,
namely \somewhere and \atpage but they both have drawbacks.
\somewhere happily prints its text if the figure is placed on the
same double page. In fact, no text at all should be printed if the
figure is visible. Furthermore it's a little verbose to use unless
hidden in a custom macro. \atpage on the other hand doesn't hesitate
to print “see figure 1.2 at page 42” while you're on page 42.
I'm aware that automatic generation of reference text is problematic
since the text depends on the placement of floats which in turn
depends on the text which might result in oscillation. I'm not sure
how likely this is to occur in practice.
I don't know if there's interest in integrating such functionality
into the core. I attached some code, a new macro \smartref, which
takes the same arguments as \in.
\smartref{figure}[fig:somefigure]
- it prints the reference if it is on the same page
(e.g. Figure 1.2)
- it prints the reference and a customizable text if the reference
is on the next/previous page (e.g. Figure 1.2 on the previous page)
- it prints the reference and the page if the reference is further
away than one page (e.g. Figure 1.2 on page 42)
- it adapts to single-sided and double-sided layouts

That (not deleting tuc file) is delebrate (as it saves time in successive
runs). If you want to delete the tuc file, you can use --purgeall instead of
--purge.
Thanks Aditya: actually that utility file .tuc can be deleted for some
situations (for instance when one does a small test) and kept for others.
Maybe for those who do not use ConTeXt from a Terminal, but rather from editors
like TeXShop or TeXWorks, one could have a feature to pass typesetting options
to mkiv, for instance like a \setuptypesetting command, to be put in the first
five lines of a document, which accepts various parameters such as for example
\setuptypesetting[purge=yes,synctex={yes,zipped},engine=mkiv]
to pass options to mkiv. But this is probably too complicated.

Re: [NTG-context] installing two ConTeXt trees
Hi Alan, Using TeXShop on MacOS X you can create two files named « mkiv-stable.engine » and « mkiv-testing.engine » and put them in the folder Library/TeXShop/Engines The first file « mkiv-stable.engine » contains the following: #!/bin/bash source [path-to-your-context-minimal-stable-folder]/tex/setuptex context --autogenerate --synctex=1 $1 and the second file « mkiv-testing.engine » contains #!/bin/bash source [path-to-your-context-minimal-testing-folder]/tex/setuptex context --autogenerate --synctex=1 $1 (personnaly I add also rm -f *.tui *.log *.tuo *.xdv *.mp *.tmp *.top *-mpgraph.* *-mpgraph-temp.dvi *.tuc at the end of each of the files to remove auxiliary files, but you must be careful with removing such files as *.mp…). Then when you open anew TeXShop, you'll see in a small menu on top of each of your TeX file where you can choose to typeset your file with either mkiv-stable or mkiv-testing. Or you can add at the top of your TeX file the following line: %!TEX TS-program = mkiv-stable or %!TEX TS-program = mkiv-testing In case you would like to use mkii you should replace the line context --autogenerate --synctex=1 $1 with texexec --autogenerate --synctex=1 $1 and create an engine file named « mkii.engine » That's it. I hope this would be useful to you.

This is a very nice feature indeed.
Out of curiosity, I wondered whether it is possible to to have \placeinitial to
work with \definefirstline, or a variant of it: that is not only have the first
character of the first sentence as a dropped capital, but also the first line
(or first few words) for instance in smallcaps.
Another curiosity question: is it on purpose that
\definefirstline

does not produce two lines of text in smallcaps?

Re: [NTG-context] problem with Persian feature
Hi Mingranina, As Wolfgang said, if I fix the name of the key in \setmainfont (from « feature » to « features », see below), then your test works fine here (using Mac OS X 10.8.4, and ConTeXt ver: 2013.08.07 14:40 MKIV beta fmt: 2013.8.7).

Hi Tristan, If you ar eusing TeXLive and TeXShop on a Mac, when typesetting you should use a different engine than the one you use now. To do so, pay attention to menu on the top of you source file, to th eright of the « Typeset » button: there it is indicated which engine you are going to use when you typeset. Try the engine « ConTeXt (LuaTeX) ». Another solution is to install the stand alone version of ConTeXt.

Hi,
\nabla should be italic if all other math greek symbols, like \Omega, \Gamma,
\sum, ect are set in italic. Otherwise \nabla and all such symbols should be
upright.
Would it be possible to make this optional in math italics, something like
\setupmathematics[mathsymbols=italic]
or
\setupmathematics[mathsymbols=upright]
Maybe this should be set when one chooses the greek letters to be italic or
upright in mathematics.

On 19 mars 2013, at 19:47, Aditya Mahajan adit...@umich.edu wrote: […]Although most active users use ConTeXt standalone and are willing to update frequently, TL still plays an important role in introducing new users to ConTeXt. An experienced TeX user who wants to try ConTeXt is more likely to try ConTeXt distributed as part of TL rather than ConTeXt standalone. When there are serious bugs with ConTeXt TL, it gives the impression that ConTeXt is not a mature macro package. Hi, To support what suggests Aditya, I would like to say that the main issue with the current state of ConTeXt in TeXLive (either mkii or mkiv) is that most « lambda » users of TeX whom I know in the mathematics world and in accademia, that is: --- users who are not familiar with what should be changed in TeXLive, --- users who don't even know TeX and LaTeX are not synonyms, --- users who don't know that there exist another environments and macro packages for typesetting tex-files, --- users who don't know that using ConTeXt one can do better typesetting, and that it has better features, all those users are not going to install a stand alone ConTeXt. They would use TeXLive, they would try everything in it, but all they want is to write a paper and typeset it with a TeX package with a single command (or in the case of Mac users, from within TeXShop or another editor). Most of them do not even know where TeXLive sits on their computer, and they don't know how to install something new. Unfortunately, the ConTeXt in TeXLive does not work out of the box: the user has to issue a few commands before he can typeset a file with ConTeXt, either mkii or mkiv (for instance on my installation of TeXLive, after having issued a few commands, which I don't remember right now, I can use ConTeXt with LuaTeX, that is mkiv, but I cannot use mkii). For my part I have been advocating ConTeXt among my colleagues (especially for course materials and books, since submitting a paper to a journal is essentially impossible if it is a ConTeXt file). Most of them agree that ConTeXt gives a much better result, but when it comes to how to use ConTeXt from TeXLive they are afraid and don't go further. For some of them I have installed a stand alone ConTeXt, but most of them do not update their installation, since they would not use the most recent features or improvements (for most of day to day typesettings, when one does not use complexe features, even a beta version is sufficiently stable for such users). So my pledge is this: make any stable version of ConTeXt in TeXLive so that it works and typesets a tex-file « out of the box », without needing to issue any command other than: context myfile.tex This is the case with LaTeX inside TeXLive, and so I cannot see any strong reason for ConTeXt not having the same behavior.

Re: [NTG-context] Fixed Line Height
Hi Troy,
You are right, I am responsible for the old
http://wiki.contextgarden.net/SlideWithSteps
which is just adapted from what I used to use in the old good times of Plain
TeX. But I wasn't successful in changing the macros to make them work in mkiv.
I think the approach should completely change in order to use steps with mkiv
and lua.
Later on I'll send you some thoughts about this.
Best regards: OK

For the record, these are not my macros. Aren't they yours? Anyway, the
only thing I changed from what's on
http://wiki.contextgarden.net/SlideWithSteps
is I changed \eject to \page[yes] and I changed \phantom{ ... } to
\setlayer[StepsHiddenLayer]{ ... } where StepsHiddenLayer is a hidden
layer. Like you said, the problem seems to be that I cannot do
\setlayer[StepsHiddenLayer]{ ... }
on a row of an align. Surely there is a solution to this. I will post it
now to a separate post.

Re: [NTG-context] Fixed Line Height
Hi Troy,
Thanks for sharing!
Your macros slide-with-steps are very nice and the steps shown in the file
foo.tex are very good, but I couldn't typeset the other file, bar.tex, since it
seems that due to the use of \startalign and \stopalign in some steps in the
middle create some difficulties for TeX.
André Caldas (who is on the list) tried also some nice modifications of the
stepping macros which he maned simplesteps: maybe both of you can look at each
other's approach and solve the remaining problems.
I'll try to find a workaround for your approach with layers, maybe with using
buffers, layers and some lua code, but even though I have some (obscure…) ideas
I am really not good at writing code.
Best regards: OK

It seemed not to like \eject and I replaced \phantom{ ... } with
\setlayer[StepsHiddenLayer]{ ... } where StepsHiddenLayer is a layer created
with
\definelayer[StepsHiddenLayer][state=stop]
See attached slide-with-steps.tex
This seems to work fine with itemized lists and even MetaPost figures (see
foo.tex) but it fails with multiline equations (bar.tex) which are both
attached. I would like a solution that would allow me to reveal each line of
a multiline equation.

Re: [NTG-context] \goto links to figures are inactive
Hi Alan,
I guess you are using mkiv, since in mkii your code seems to work here.
Then, I think the way references to floats should be entered have changed and
one should use a construction such as:
\setupinteraction[state=start]
\starttext
\goto{Figure A}[fig:cow.pdf]
Reference to Figure A on page \at[fig:cow.pdf]
\goto{Table 1}[tab:Table01]
\goto{Some text}[Text]
\page
\startplacefigure[reference=fig:cow.pdf,title=Figure
A][here,page,force,nonumber]
\externalfigure[cow.pdf][width=.5\textwidth]
\stopplacefigure
\page
\startplacetable[reference=tab:Table01,title=Table 1][here,force,nonumber]
{\starttabulate[| l | l |]
\NC 1000
\NC 2000
\NC\NR
\stoptabulate}
\stopplacetable
\page
Some text\reference[Text]{}
\stoptext
which gives appropriate working links.
There should be also a short version of \placefigure or \placetable, but I
don't remember the correct syntax… Sorry!

Re: [NTG-context] Math typesetting problems
Hi Janne,
Personnally I prefer to use the Plain TeX alternative \over (which works fine
in ConTeXt), that is
${a \over b}$
instead of
$\frac{a}{b}$
Compare the following two outputs in the example you want to typeset: I think
the second is more or less what you want
\starttext
Using \type{\frac} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = \frac{e^{-\frac{(u-s)x^2 - 2x(S(u-t) +
U(t-s)) + \frac{(S(u-t) +
U(t-s))^2}{(u-s)}}{2(t-s)(u-t)}}}{\sqrt{2\pi\frac{(t-s)(u-t)}{u-s}}}
\stopformula
\blank
Using \type{\over} gives:
\startformula
f_{B_t | B_s = S, B_u = U}(x) = {
e^{-{(u-s)x^2 - 2x(S(u-t) + U(t-s)) +
{(S(u-t) + U(t-s))^2 \over (u-s)} \over 2(t-s)(u-t)}} \over
\sqrt{2\pi {(t-s)(u-t) \over u-s}}}
\stopformula
\stoptext

Hi,
Thanks to Hans and Wolfgang for your attention and the workarounds you offer.
When I want to refer to an un-numbered section, it makes sense in an
interactive document. Maybe, instead of
\in{other section}[sec:other]
I should use another command such as
\about[sec:other]
but in this case all the title of the section in question will be typeset: this
is fine when this title is short enough, but it may be ugly if the title is

I noticed that with the latest mkiv (version 2013.01.22 18:33 MKIV fmt:
2013.1.22) when the sections have no numbers two « ! » are printed and this
behavior is new: with previous versions when invoking for instance
\in{other section}[sec:other]
there used to be a link to the other section and no « ! ! ». I understand
that there has been a change in this behavior, but is there a way to suppress
the two « ! ! »?
Here is a minimal example:
begin bug-reference.tex
\setupinteraction[state=start]
\setuphead[section][number=no]
\starttext
\section{First Section}
\input knuth.tex
See the \in{other section}[sec:other] below.

Re: [NTG-context] hbar (and probably some other symbols) doesn't work in latest beta
Dear Michael and Dalyoung,
In order to test again and reproduce the problem you encounter I removed my
texmf-cache and typeset the example: here is what I observe.
--- with \enablemode[lmmath] the \hbar appears and is a math italic « h » with
a bar in the top third of the vertical part of the letter
--- without \enablemode[lmmath] the \hbar appears and is a roman « h » with a
bar in the top third of the vertical part of the letter
Your error message seems to indicate some character in
texgyretermesmath-regular is not found and points to the file
mkiv-base.map
is this file present on your context tree? On my installation the file exists
but there is no mention of texgyretermesmath-regular…

Re: [NTG-context] hbar (and probably some other symbols) doesn't work in latest beta
Hi Michael,
I am also using Mac OS X Mountain Lion 64 bit and LuaTeX version
beta-0.74.0-2012122517 (rev 4541) with ConTeXt ver: 2013.01.02 18:19 MKIV.
It seems that your installation has a font problem, but I can't tell what is
the origin.
Could you please try your file with some other fonts such as on of the
followings:
%\setupbodyfont[xits,12pt]
%\setupbodyfont[palatino]
%\setupbodyfont[libertine,12pt]
%\setupbodyfont[termes]
%\setupbodyfont[times,12pt]
Another issue maybe the fact that Latin Modern Math has been changed recently
under mkiv, and one way to use the old Latin Modern Math is to say:
\enablemode[lmmath]

Re: [NTG-context] New module: simplesteps.
Hi André,
You were so quick to write your module…
Thanks for sharing, but I could not typeset the example file you sent: I didn't
get whether your file simplesteps.mkiv should be renamed
simplesteps.mkiv
or
simplesteps.tex
or even
t-simplesteps.tex
or any other suffix.
Maybe after you apply the changes suggested by Wolfgang and Philip you are
going to repost your moudle?
Best regards: OK

Hello!
thanks for the interesting contribution! Have a look at the patch
I hopefully don’t forget to append.
Thank you! I will take a look and learn... ;-)
[...]
I use \startbuffer and \stopbuffer, and also Lua. As I said, I don't
really know how to write a module... comments are very welcome.
Honestly, it doesn’t work, but that’s a minor flaw!
Sorry! I forgot to mention. Only a little subset of it works. I have
(already - so I don't forget to) attached a tex file that works.
[**lots of advices I will study carefully latter**]
[...]
I could not figure out how exactly the section block thingy is
supposed to work. It does not create the \startframe macro at all
-- is this something custom?
I don't know how to use this startframe yet. So, I am doing like
this right now: (numbers like 2-3 or 2- don't work yet)
=== START code snip ===
\startbuffer[simplesteps]
\startitemize
\item First item
\uncover[2,3,4]{\item Second item}
\uncover[3,4]{\item Second item}
\uncover[4]{\item Second item}
\stopitemize
\stopbuffer
\simplestepsplaybuffer
=== STOP code snip ===
The simplestepsplaybuffer macro simply calls the
simplesteps.playbuffer() lua function. This function plays the buffer
and determines if it has to be played again or not. If it does, then
it tex.print('\simplestepsplaybuffer').
The macros uncover determine how far the specification is from being
played. If it is being played now, then show. If it is played next,
then show in gray. And so on.
I infer it’s about the slide title
so I have \startframe call \section but that should be taken as a
placeholder at most. In my own slide module I use
\{start,stop}section with the option placehead=no and rely on the
page header to display the slide title (i.e. current section
running head). That was the laziest way I could imagine :P
I guess that's what I want to do. I just don't have the necessary
knowledge yet. ;-)
Some remarks:
- you should rename simplesteps.mkiv to t-simplesteps.mkiv,
indicating that it is a thirdparty module
I will. I think I will have a bitbucket repository exclusively for
modules. Then I will have the proper directory structure, the proper
naming scheme and hopefully proper documentation, xml, etc. (lots of
things to learn!)
- if you plan on expanding the code you eventually will come to
love this bit: http://wiki.contextgarden.net/System_Macros
- Context has a namespacing system which you might consider
switching to in the long term:
http://tex.stackexchange.com/q/58654
but it’s arguably an advanced method
Well, I do want to do it the right (recommended) way!
- maybe switch to mkvi as named parameters make rewriting
macros a breeze
Would you elaborate a bit further?
Is it ok if I send a PDF sample to the list?
I hope you can use the TEX file attached.
Cheers,
André Caldas.

Hi all,
a first version of the 'drops'-module (MkIV only) is available at
https://www.wuala.com/indiego/public/ConTeXt/drops/?key=caiCGLasLFmJ
Taken from the included documentation..
[..]
'drops' is a small extension for ConTeXt, that allows you to add drop
shadows to rectangular regions (so called boxshadows). A working
installation of ImageMagick (IM) is required to create the shadow
graphics. The supported color spaces are CMYK, RGB and Gray, the file
formats are limited to PNG and JPG.
[..]
Read the manual for detailed information.
The attached example is just a small test file for the 'rotation'
parameter (a compensation for the object rotation, so that the shadow
stays at the given direction). You will find other examples in the
documentation and there is also a 'pile' example with the complete
source. The 'presets' pdf contains the predefined setups for different
shadow (or frame) types and it's source is a good starting point for
your own experiments.
This is a first draft, but most things work quite stable. If you want to
help, test as much as possible. :-)
*You need a recent version of ImageMagick for this module.*
6.7.8-2 to 6.8.0-7 (wrong version info 6.8.0-6): used here, should work
6.7.6-0 or lower: will fail due to incompatibilities
7.0.0.0 alpha: untested ('magick' is used instead of 'convert')
Tested on Windows7 64bit and Debian 6.0.5-i386 (IM compiled from source)
Happy TeXing!

Dear ConTeXt list,
I apologize for digging up an old thread. I was searching for
\starthangaround[right] and found this thread. I tried the code that Wolfgang
gave in this thread but I guess something has changed since then, because it
does not work with latest minimals. Would it be possible to get (a working)
version of \starthangaround[right]? I think it even would be nice to have it
in the core.
As a minimal nonworking example, see the email from Wolgang in this thread.

concerning the bug reports …
Hi Hans,
Thank you for the fixes and adding the commands \notin and \imply: I did some
testing with your examples and others of my own, and it seems that some of the
issues are fixed.
However with
\enablemode[lmmath]
the command \notin does not work as expected, while when the above command is
commented out it does.
Another issue is that the size of integrals when using palatino, times or
termes is the almost the same as the ones in inline maths, and I think that
this is not the correct behaviour.
The examples I tested are essentially yours:
%%
%\enablemode[lmmath]
%\setupbodyfont[xits]
%\setupbodyfont[palatino]
%\setupbodyfont[dejavu]
%\setupbodyfont[times]
%\setupbodyfont[termes]

Re: [NTG-context] \not\in doesn't work properly
Hi Hans, Hi Jeong Dal,
On November 21st I reported this issue and others with the new versions of mkiv
where math characters are treated with a new method.
Indeed the issue appears with Latin Modern and their new implementation.
However with some fonts the behaviour is correct but the size of some signs
(such as \int, \sum, \prod) is incorrect even with those fonts.
As I understood it if one adds
\enablemode[lmmath]
at the beginning of the file then mkiv uses the good old implementation, at
least when using Latin Modern.
The minimal test file is this:
%%% begin bug-lm.tex
\starttext
The commands \type{\imply} is not anymore defined.
\type{\iff}, \type{\Longrightarrow}, \type{\mapsto} and some other arrows do
not appear.
\startformula
(\pi \notin {\Bbb Q} \Longrightarrow \pi^2 + \pi \not\in {\Bbb Q}) \iff \pi^2
\not\in {\Bbb Q}
\stopformula
\startformula
x \mapsto ax+b
\stopformula
\stoptext
%%% end bug-lm.tex
and the PDF output is attached to my previous message.
Best regards: OK

I've changed the defaults for the math fonts so that now we use the 'real

document (of in cont-syst.tex):
\enablemode[txmath]
\enablemode[pxmath]
\enablemode[lmmath]
The design sized latin modern text font is still the default but one could
already change that by
\setupbodyfont[modern]
There is currently some renaming going on for those math fonts but that
should not affect us as context can handle older names too.

Re: [NTG-context] \startitemize[columns] once again...
Hi Marcin,
I think there is a small bug with itemize and columns: in another thread (with
Subject « vertical alignment problem in column items» ) Dalyoung reported also
an issue, which is related to what you have observed.
Please see my message in a reply to Dalyoung's message, where I reported some
testings but I am not sure when this bug appeared (in mkii, the behaviour is

Hi Marcin, appears like the vertical spacing is extended when

Re: [NTG-context] vertical alignment problem in column items
Hi Dalyoung,
I think that there must be a small bug in mkiv regarding itemize in columns,
but at the same time I think that the problem comes from the fact that in your
example you use inline maths and fractions: this perturbs the way the
horizontal and vertical distances are calculated by mkiv. It seems that mkiv
considers there is not enough horizontal space to put the four items in a row.
If you use two columns the problem is solved, as you can see in the following
examples (please typest it both with mkii and mkiv to see the differences).

one gets a 3x3 matrix whos coefficients are b_{11},…b_{33}.

Now, I write a matrix using \startluacode by the helps of you.

In this code, I have to give all the entries of a matrix as a table. It is
good to use in many cases.

works well.
However, there might be a better way to do job using for iteration.
I tired to use i, j in several ways but it doesn't work.
Inside a string the variables are just bytes. To print to a
string you can interpolate with string.format() [1].

\startluacode
document = document or { } -- recommended: use namespace
document.print_matrix = function (x, y)
if not y then y = x end -- default to square
context.startmatrix{left = \\left(\\,, right = \\,\\right)}
local schema = a_{%d%d} -- %d: prints integer part
for i=1, x do
for j=1, y do
--- use the template defined above to print the
--- row and column
context.NC(string.format(schema, i, j))

context.NR()

Hello,
I am using a the startsetups mechanism that defines a title page in my
environment file. That way anyone creating a document in my organisation can
create a new document and get a consistent look of the title page. There is
one problem with this: On occasions I get very long document titles and then
the title extends over the left-hand edge of the page. I would like to
incorporate a new line into the document title; I'd even be happy to do that
manually, ie. it does not have to be automatic.
There are two problems here:
1. I had not had any success with putting a newline into the title; it will
need to be not where the titlepage is defined but where it is used (see
below). I have tried \par and \\ and none of them work.
2. Assuming I found a way to do this, I would need to also find a way of
reducing the \blank[170mm] by the amount that the second line of the title
takes up to render the information down the bottom in roughly the same place.
If push comes to shove, I could create a second titlepage setup for two-line
titles, but I much rather not. Is there a solution to that? Is there maybe a
way to position the information down the bottom absolute?
Here is minimal example (or something very close to that):

Re: [NTG-context] Numbering subformulas
Hi Andreas, Wolfgang and Aditya, Thanks for your attention and suggesting a fix. However, after I applied the change mentioned by Andreas for the definition of \strc_formulas_handle_sub_numbering in cont-new.mkiv and made the formats anew, the subformulas are not numbered as expected. Probably we have to wait for a fix from Hans in an upcoming beta. @Wolfgang: can the typo you mention in font-new.mkiv be easily fixed? Best regards: OK On 15 oct. 2012, at 12:44, Andreas Mang m...@imt.uni-luebeck.de wrote: Dear all, Dear Wolfgang, This is already in the core (str-mat.mkiv) but I found a typo in another macro in font-new.mkiv Thanks. That's indeed interesting. I still get an error. I have deleted everything and have updated to the most recent beta: 2012.10.06 15:31 MKIV fmt: 2012.10.15 If I replace the function \strc_formulas_handle_sub_numbering as described before, erveryting works nicely. Probably your fix has not yet been uploaded, yet. I just wanted to let you know. Maybe this clarifies something or indicates additional problems.

Re: [NTG-context] Subscript Depth
Hi Nick,
As far as I can say from my own experience TeX, that is both plain TeX and
ConTeXt, treat the subscripts differently according to whether there is also a
superscript or not: please see the following examples:
\starttext
Compare $a_{b}'a_{b}$ and $a_{b}'a_{b}^{}$
\stoptext
Best regards: OK

Hi,
How would I go about getting subscripts to stay at the same depth? An example
of the problem I'm having is:
\starttext
% Notice the b's are not aligned
$a_b' a_b$
\stoptext
I'm only just learning ConTeXt and TeX, so I'm not sure what I'd need to
change to fix this.
Thanks,
Nick

I don’t know if the bug was also in the stable but it’s in the beta version I
use. You can use the following example to check for the bug:
\starttext
\placeontopofeachother{A}{B}
\stoptext
Hi I can confirm that the bug is present in recent betas, that is
\placeontopofeachother
is broken, but Context version 2011.11.29 works fine with your example.
