Re: [NTG-context] math symbol for "is an element of"
Thank you, Hans! The links you gave me provide me with another useful tool in my toolbox (which I had not been aware of before). In this particular case, as Wolfgang pointed out, \in actually does work to get the desired symbol in math mode. But it is good to know how to use text substitutions too.

Re: [NTG-context] math symbol for "is an element of"
My sincere apologies. I tried to do my homework to avoid wasting everybody
else's time with a silly question, but apparently I did not do so adequately.
You're quite right -- it works with no problem. It was something else nearby
that was causing my minimal example (apparently not minimal enough) to fail.
That being said, the link to "\in" on the Math Basics page does point to the
wrong place (the "\in" command used for references). I'll go correct that as my
penance for asking such a ridiculous question.
Thanks, and again my apologies,
Sciurus

A quick question for the ConTeXt mailing list:
Other than typing it directly (or cutting and pasting it), how does one get
the character ∈ (in case this gets garbled in emailing, this is supposed to
be the mathematical symbol that looks more or less like an epsilon, and
which is the mathematical symbol for "is an element of" a set).
\showmathfontcharacters gives the following information about it:
U+02208: ∈ ∈ element of
width: 524262, height: 426798, depth: 33798, italic: 0
mathclass: relation, mathname: in
I'm not completely sure how to read this information, but if I read it
correctly, perhaps this character should be gotten with \in. Also, the Basic
Math page of the Wiki (https://wiki.contextgarden.net/Math/basic) states
that you should be able to type this character with "\in". But that doesn't
work (even inside a formula), since \in is used for references in ConTeXt.
And in fact the link on the Basic Math page for \in takes you to the
explanation of \in as used for ConTeXt references.
This is a very common character in mathematics, so I wanted to ask: what is
the recommended way to type this character? (I'm hoping to avoid having to
cut and paste the character into the document every time I want to use it.
And I don't have a utf enabled keyboard that would allow me to type this
symbol readily from the keyboard.)

Re: [NTG-context] defining font family for several options
Thanks Otared. That clears up that little item :-)
BTW I know how to reduce font size in the headers (chapter titles) that
appear on the recto pages, which I can do with something like
\setupheader [style={\ss\switchtobodyfont[10pt]}], but it doesn't seem
to affect the header (title of the book) on the verso pages, which is
drawn from the simple statement:
\startdocument
[metadata:title={Book title}]
Shouldn't \setupheader affect both headers? Or is it possible I have
left something out of my \setupheader declaration?

hurry, but when you have a moment can you explain the significance of the ~ in
the {\bf\ss #1.~#2}}part of the definition, before the 2nd element?
After this I'll go back on list! I still have a couple of other queries (not
font related) about things that are not functioning as they ought at the

as always there are people on the list like yourself who are prompt with their

Hi Julian,
First of all, your definition of mychapterfont is incomplete: a font family
should contain also math fonts, because even if you don't have mathematics in
your text where you use that font, ConTeXt may pick some characters from math
fonts. So in my opinion you should define a whole font family named
mychapterfont, where in particular the sans serif comes from what you are
indicating.
The second point is that you should not setup bodyfont twice: when you say
twice \setupbodyfont, ConTeXt will take the last one for the rest of your
document…
So you say only once
\setupbodyfont[mainface]
and then only where you want to change the font you say
\start \switchtobodyfont[mychapterfont] \ss My special text. \stop
By the way, as we said earlier, you can also use braces instead of \start\stop,
and even better you can say
\start \switchtobodyfont[mychapterfont,sans] My special text. \stop
A third point is that if you are using mychapterfont only to set the titles of
chapters, in my opinion it would be better to define a command which takes care
of all the formatting you are wishing, and then use it in the chapter header.
Something like
\define[2]\MyChapterCommand{\switchtobodyfont[mychapterfont,12pt] {\bf\ss
#1.~#2}}
\setuphead[chapter][command=\MyChapterCommand]
In this way you can just say
\startchapter[title={This is my first chapter}]
\input ward.tex
\stopchapter
without the hassles of formatting each title. If only some chapters have the
special font, then you can define a new family of chapters which may share the
same counter as the rest of your chapters.

Otared, I thought I had it right - and it is partly right, but that newly
declared font now applies to everything, not just the chapter title. So I
haven't got it quite right! Maybe I shouldn't bother the list with these extra
bits so am writing off list. Here is what my font definitions now look like
(new one highlighted):
\definefontfamily [mainface] [rm] [alegreya] [sc=file:alegreyasc-bold]
\definefontfamily [mainface] [ss] [dax][tf=file:dax-regular,bf=file:dax-medium]

[ss=file:itcavantgardepro-md]
\setupbodyfont[mainface]
\setupbodyfont[mychapterfont]
I presumed I would have to \setupbodyfont[mychapterfont], but is this where I
have gone wrong?.
Then in the first chapter, I wrote as follows:
\chapter{{\switchtobodyfont[mychapterfont] \ss Introduction to the BDACE Online
Project}} and I am getting my AvanteGardePro-MD font alright, but it now
applies to the whole document!
I tried following title with \start switchtobodyfont[mainface] \rm and then my
body text (followed by \stop obviously, at the end of the chapter). But this
did not work.
I then thought that I could use this [mychapterfont] and include it somehow in
my \setuphead[chapter] so it would work for all chapter titles, along the lines
of: \setuphead [chapter] [header=empty, {\switchtobodyfont[mychapterfont] \ss}]
but that hasn't worked either - my body text throughout is still in the sans
serif, not the usual [mainface] [rm]

[NTG-context] Defining \qed (was: Bug with \wordright...)
Hi Wolfgang,
Thanks for your explanations and the correct definition of the close symbol in
an enumeration.
Following up the discussions with Hans, in order to put a close sympbol at the
end of a formula, I have the following for the definition of \qed:
%% begin example-qed.tex
\showframe
\definesymbol[Fin][\mathematics{\square}]
\def\qed{%
\ifmmode
\inrightmargin{\hskip-7.5mm\symbol[Fin]} % --> attention here
\else
\dontleavehmode\wordright{\symbol[Fin]}
\fi}
\setupformulas[location=left]
\starttext
One sees that
\placeformula
\startformula
a^2 + b^2 = c^2
\stopformula
which is the Pythagoras theorem. \qed
Another proof of Pythagors theorem is based on the figure below in which one
sees that:
\placeformula
\startformula
(a+b)^2 = c^2 + 2ab \quad \imply \quad a^2 + b^2 = c^2. \qed
\stopformula
\stoptext
%% end example-qed.tex
Now how can I replace « \hskip-7.5mm » (which was found by trial and error…) in
a robust manner so that the close symbols in the formulas are vertically
aligned with the close symbols in the text?
In other terms can one compute automatically the amount of negative \hskip so
that the definition is correct when one changes the font size and the layout?

1. \symbol is meant to access pre defined symbols, as fallback method

This fallback is in my opinion problematic because it's easy to miss it.
\starttext

2. When you use the closesymbol for a enumeration ConTeXt uses also the
argument of the closecommand to apply something to the symbol, by
default the argument to the closecommand key is \wordright.
This means you're putting \wordright (which itself is flushed as symbol)
within \wordright which has to fail at some point.
Below is a cleaner version to put a symbol at the end of each proof. The
\blank setting in the \PlaceProofSymbol definition moves the symbol back

Hi Hans,
Thanks for the hint which consists in adding an \ifmmode to the definition of
\qed.
However, as you suggest, one needs some other mechanism in math mode, since
with your new definition of \qed the alignment of the formula changes when one
adds this close symbol:
begin-example-qed.tex
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\ifmmode\quad\symbol[Fin]\else\strut\wordright{\symbol[Fin]}\fi}
\starttext
\startformula
a^2 + b^2 = c^2.
\stopformula
\startformula
a^2 + b^2 = c^2. \qed
\stopformula
One sees that\type{\qed} in the formula changes the alignment of the formula.
\qed
\stoptext
end-example-qed.tex
Thanks a lot for everything: Otared

One can debate if the old behavior was ok ... wordright is meant for
adding something at the end of a paragraph and you have none here. You
can add a \strut in your definition to force a line.
The lmtx implementation actually permit this:
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\strut\wordright{\symbol[Fin1]}\wordright{\symbol[Fin2]}\wordright{\symbol[Fin3]}}
\starttext

i'm still exploring this but it has to do with collecting stuff, as in:
\wordright{before} test \par
test \wordright{before} \par
(i'll look at the number issue which indeed looks a like a bug)

[NTG-context] Bug with \wordright in LMTX version 2020-08-03 14:25
Hi Hans,
A file which used to be typeset correctly with the previous versions of lmtx,
now produces an error. Despite the error message being extremely cryptic:
Error ! Missing number, treated as zero
I could guess the origin of the bug, which seems to be \wordright, but
although the following minimal example shows a bug it does not produce the same
ERROR output page:
the square ''end of proof''
\definesymbol[Fin][\mathematics{\square}]
\def\qed{\wordright{\symbol[Fin]}}
\starttext
\startformula
a^2 + b^2 = c^2
\stopformula
\qed % the problem is here
\stoptext
In the above example if one adds something before \qed, then the square
end-of-proof appears.
However in my real file ConTeXt ouputs an error page and says: Error !
Missing number, treated as zero.

[NTG-context] Notation of the first derivative in mathematical mode (lmtx)
Hello,
I replaced the context engine with the lmtx engine but I find that the
derivative symbol is too high regardless of the font used.
I mainly use modern and pagella because I type many texts using
mathematics: can we correct this problem,

the code written by Wolfgang and tried to include the graphics in it. The

Re: [NTG-context] Converting from LaTeX for PDF accessibility tagging?
Thank you very much - I think the problem was with a LaTeX "align" environment which pandoc translated into a setting which ConTeXt didn't recognize. These equations were monsters, so I'll try with simpler equations to give you an idea. But in fact what you say makes perfect sense, and I'll go back and read through the mathematics document again, and more closely this time! (For matrices and arrays I still prefer the neat LaTeX implementation, but maybe that's simply my general unfamiliarity with ConTeXt.) Thanks again!

Re: [NTG-context] Unexpected symbol with Enumeration

[NTG-context] mathring circle above a letter
Hi all,
The \mathring command puts a small circle above a letter, but in some fonts
(namely Lucida OT) that circle is too small. So thanks to a hint by Hans and
Wolfgang some years ago I use the following definition which works fine when
used alone. But in maths, one needs sometimes to use it with the command
\overline (or \overbar) and the result is not nice.
Can someone tell me please whether it is possible to modify the \mathring
command so that th ecircle is a little bit larger, or the one I define below as
\interior in order to have a correct result (more clearly said: I would like
the small circle to be put above the bar which is itself above the A in
$\interior{\overline{A}}$).

I only use Markdown and pandoc, because they provide a limited way of XML code easily. The real thing is that you can feed ConTeXt with XML sources to typeset what you want. My use of XML typesetting is basic when compared to that of Hans, Taco, Thomas Schmitz and Hans van der Meer. Of course, other approaches are perfectly fine. My comment was only about not focusing on pandoc-xhtml (which I should rewrite from scratch when I find time for that), but on what makes it thick.

Many thanks. The issue is clearer now, e.g.,
===
When used in mathematical context (MathML) it is recommended to
consistently use style markup for superscripts and subscripts. This is
because mathematical layout allows not just individual symbols, but entire
expressions to be superscripted or subscripted in a regular, nested manner.
===
Of course, consistent use of style markup means that we can't naively
extract superscript text from the pdf, e.g., \CATCA becomes 𝓒nt.
OTOH, issues 4.i and 4.ii below are still perplexing. Are there any
workarounds?
Thanks again.

Dear gang,
Ok, I've made some progress:
1. tex-gyre etc. *do* support Unicode mathematics, but the version of
ConTeXt I was using had produced the wrong encoding in the pdf output. For
example, U+1D4D2 (𝓒) in the input was being mapped to U+2D4D2 in the
output.
Updating to the latest beta appears to have fixed this issue.
2. tex-gyre etc. appears to be missing some superscript characters, e.g.,
ⁿ (U+207F).
3. New example:
===
\setupbodyfont
[cambria,12pt]
% [pagella,12pt]
% [times,12pt]
% \starttext
\startTEXpage
\def\ANTI{{^{\rm nt}}}
\def\ANTIU{{^{\rm ⁿᵗ}}}
\def\CATCA{$\cal \bf C\ANTI$}
\def\CATCAU{$𝓒\ANTIU$}
𝓒 \CATCA \CATCAU
\stopTEXpage
% \stoptext
===
\CATCAU and \ANTIU use Unicode characters and superscripts directly,
instead of the old TeX method.
4. Issues. In the pdf output of \CATCAU:
i) Why does ConTeXt make the second superscript larger than the first?
ii) If one copies the text of the pdf output to an editor - even this
email client - the second superscript moves to a new line:
𝓒 ⁿ
t
Why does this happen? Is this a bug?
5. Here is what we want: 𝓒 ⁿᵗ
What is the proper or best way to get a character-superscript combination
in ConTeXt whose output can be copied and pasted to an editor and give the
correct result? What am I missing?
Thank you in advance.
Best wishes

Re: [NTG-context] two different outputs.
Jeong Dal schrieb am 01.01.19 um 23:28:
Dear Wolfgang,
Thank you for the solution at the new year’s day.
Your sample works very well. It is what I want.
I copied it into my file and run it, then I got a strange output.
Everything is OK except outer effect text is written twice.
I don’t know what makes it write twice.
I can’t reproduce the effect with your included example.
What I guess is that one of your setuos still contain the line
\setuphead[title][textcommand=\TitlePage]
and you apply the effect twice because when you take a closer look
at the image you can see even the inner effect appears two times.
I have two more questions.
1. I’d like to put a title only in a page using the following. How to
put a title as center aligned?
\setuphead[title][align=middle]
%
\page[yes]
\dontleavehmode\blank[5cm]
\title{Why, Math?}
\blank[big]
\midaligned{\fancy Why do we learn mathematics?}
\vfill
\midaligned{\tfb Institution}
\blank[2cm]
\page
2. Is there a way to remove a pagenumber from the title page?
\startstandardmakeup[align=middle]
\blank[5cm]
\title{Why, Math?}

It works in many cases that item content ends with words. But it is not working
if the item contents end with \stopformula. If I put \placeclosesymbol before

Anyway, it works in most cases.

For display equations, there is not easy solution. (What should happen if
there is an equation number; what should happen if the display equation
overflows hsize, etc.). The latex package `ntheorem` implements a two pass
solution (measures where the equation number box gets placed, and then add
the close symbol below it). I am not sure how easy it is to implement such
an approach in ConTeXt.

Re: [NTG-context] closesymbol on same line as displayed formula
Hi,
I am sorry to bring up old topic “Re: closesymbol on same line as displayed
formula” again.
(ntg-context Digest, Vol 153, Issue 40)
Is there any progress after that?
It seems to me that there is no more discussions about it.
The same thing happens after the itemization as in the following MWE.
Thank you for reading.

Re: [NTG-context] xrightarrow is not straight
Dear Alan,
Thanks for the reply! Using \definemathstackers I can set the voffset to adjust
the vertical spacing. This is exactly what I needed, thanks!
However, I couldn't use the ahlength variable. I tried different values, but it
doesn't seem to change anything (and the current arrowhead is tiny). (Using
startMPcode and drawarrow gives a big arrowhead.)
Also I noticed that the content of \rightarrow{...} was not in mathmode, so I
tried using middlecommand=\mathermatics (I found this on the wiki and in the
docs). But that doesn't change anything. Is this a bug?
Example:
\useMPlibrary[mat]
\definemathstackers [mp]
[alternative=mp, voffset=-.3\mathexheight, middlecommand=\mathematics]
\definemathextensible [mp] [rightarrow] ["2192]
\startMPinitializations
ahlength := EmWidth ; % Does not work?
ahangle := 30 ;
ahvariant := 1 ;
ahdimple := 4/5 ;
\stopMPinitializations
\setuppapersize[A7]
\starttext
$A \rightarrow{$\neq f$ and $\neq g$} B$
$A \rightarrow{\neq f \text{ and } \neq g} B$ % Is not typeset in mathmode
\stoptext
Thanks in advance,
Kind regards,
Joshua

Hello,
You can also use MetaPost to render math stackers, rather than relying on TeX
constructs and any particular font.
For example:
\useMPlibrary[mat]
\definemathstackers
[mp]
[alternative=mp]
\definemathextensible [mp] [leftarrow] ["2190]
\definemathextensible [mp] [rightarrow] ["2192]
\definemathextensible [mp] [leftrightarrow] ["2194]
\definemathextensible [mp] [longleftrightarrow] ["27F7] \definemathextensible
[mp] [rightoverleftarrow] ["21C4]
\definemathextensible [mp] [underbrace] ["FE3DF]
\setupbodyfont [dejavu-condensed,12pt]
\starttext
$\rightarrow{≠a}$
\stoptext
Furthermore, the MP arrow can be tuned
\startMPinitializations
ahlength := .5EmWidth ;
ahvariant := 1 ; % dimpled straight
\stopMPinitializations
as can line widths, etc.

Also, sometimes the context requires a new key, such as foregroundcolor= and backgroundcolor=, when color= for example would be ambiguous. Thirdly, many keys are inherited and passed-on to an included command. Finally, unknown or unused keys are simply ignored. This has the advantage that often, just trying the obvious simply works. To quote Poincaré: \startquotation Mathematics is the art of giving the same name to different things. It is enough that these things, though differing in matter, should be similar in form, to permit their being, so to speak, cast in the same mould. When the language has been carefully chosen, one is surprised to discover that all proofs developed for a given object, can be immediately applied to many new objects; there is nothing to be changed, not even the words, since all the names have become the same. \stopquotation Alan ___ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Re: [NTG-context] text in mathematics
Hi Alan, Wolfgang and Hans Åberg,
As far as I am concerned, when I have to add a text to a math formula I use
\mbox, as in the example
\startformula
A := \left\{f : {\Bbb R}^2 \longrightarrow {\Bbb R} \; ; \; f \mbox{ is
measurable and } \int_{{\Bbb R}^2}|f(x)|dx < \infty \right\}.
\stopformula
The advantage being that if the above formula appears in an environment such as
a Theorem (where the text is typeset in italic, or slanted) the text in the
above \mbox will be also in italic or slanted.
I don't think it would be a good idea to add new commands to treat text in a
math formula: the existing possiblities are more than satisfactory, and
moreover situations where one has to add text to a formula are not that common.
So using a command like \mbox, or \text, or \mathtext, or whatever, is not that
time consuming.

Re: [NTG-context] text in mathematics
Hi Alan,
1. The correct way to use \mathrm is {\mathrm ...} because it is a
switch like \rm for text mode.
2. \mathrm is the wrong method to write text in formulas because the
command changes only the math alphabet. This means no ligatures, kerning
or other characters like umlauts.
3. The correct way to write text in math mode is \mathtext (which has
the synonym \text) or \mathword. To change the style of the text you can
use \mathtext{\it …} or \mathtextit{…}.

Hello ConTeXt users,
Does it drive you crazy to see TeX users write $t = time$?
(I see this all of the time by LaTeX users in Beamer presentations.)
One can do better writing $t = {\rm time}$ (maybe)
or in ConTeXt $t = \mathrm{time}$.
Sometimes, too, I might write $t = \text{time}$.
We also have the commands \mathematics{} that can be used in place of
the TeX shorthand $...$, and this also has the shortcut \m{...}.
I thought that it might be useful to have an equivalent escape, to be
used as $t = \t{time}$. What do other users think?
OK, \m{t = \t{time}} might be a bit funky...
Alan
P.S. I proposed doing this via
\let\t\mathrm
but Hans tells me that this is not good, as \mathrm{} does not give
proper font processing, so implementation of \t{} would be something
different...

The last would be easiest to remember when using it less often. Strictly, it is
different, because it could mean italics, as may be used in formulas. The
upright letters are called normal here:

If one is using italics for text in math formulas, that would be logical.

Re: [NTG-context] latest beta and \seeindex
"Mathematics is the art of giving the same name to different things. It
is enough that these things, though differing in matter, should be
similar in form, to permit their being, so to speak, cast in the same
mold. When the language has been carefully chosen, one is surprised to
discover that all proofs developed for a given object, can be
immediately applied to many new objects; there is nothing to be
changed, not even the words, since all the names have become the same."

Re: [NTG-context] Fonts and equations
Henri, Thanks for the suggestion. I tried to add the additional fonts, but this did not seem to make a difference. The math equations render fine, but a search performed for terms in an equation still does not work when I specify the font. When I remove the font specification, it works fine. There must be some difference in the font that is used even if I don't specify a math font. Any other thoughts about why the math font changes or how to get a math font that is searchable, or get back to the default math font? -Lance -- > > Message: 4 > Date: Fri, 18 May 2018 18:55:14 +1200 > From: Henri Menke > To: ntg-context@ntg.nl > Subject: Re: [NTG-context] Fonts and equations > Message-ID: <12743277-ebd0-67c7-2393-fe33e97bf...@gmail.com> > Content-Type: text/plain; charset=utf-8; format=flowed > > > > On 17/05/18 23:19, Lance Larsen wrote: > > I have a context document with several equations.

placing a figure at the right or left of the text using

A small step in the right direction: Blackboard letters and calligraphic
(script) letters seem to work when I add
{ name = "fourier-bb.tfm", vector = "tex-mb",
skewchar=0x7F },
{ name = "fourier-mcl.tfm", vector = "tex-sy",
skewchar=0x7F },
to fourier-math.lfg.

[NTG-context] Fourier and utopia
Dear Hans and dear list,
I try to use the fourier/utopia combination in mkiv (I used that
combination for my PhD thesis in mkii 10 years ago).
First of all, I have downloaded the fourier fonts from ctan at
https://ctan.org/tex-archive/fonts/fourier-GUT . The fonts are found by
mtxrun.
I have one folder containing type-fourier.mkiv, fourier-math.lfg and
testfile.tex. Everything seems to be found by the system, so the problem is
probably in my files somewhere. The resulting pdf after compiling
testfile.text is attached.
Any ideas of what I am missing?
Additionally, the fourier fonts come with fourier-bb.tfm (probably with
blackboard bold), fourier-mcl (probably so that one can use mathcal). Any
ideas on how to use them in the fourier-math.lfg file?
If more information is needed, then please tell me.

Re: [NTG-context] Learning how to use \setupbtxrendering
Hi Alan, and all the Gurus on the list,
Many thanks for your help and comments. I am sending again this message which,
by mistake, was sent only to Alan, in order to get some help.
The manual mkiv-publications.pdf contains indeed many explanations, but
probably the informations there are too vast for the elementary use I am going
to need. So many thanks to Alan and Hans for this extensive manual!
Now, this being said, I am neither able, nor do I need, to use the full blown
power of this environment. In particular I am not familiar with the style apa
(or aps, which seems to exist too…) or other official specifications. That is
why I would like to learn by examples, beginning with the one included on page
4 of the above mentioned manual and then modify things to see what can be done…
However, when I use the modifications which Alan suggested (for the style apa,
but I dropped the apa: prefix…) I do not get what is desired (please see below
the code and the attached test.bib file). And if I give explicitely the
specification apa, then many other things are not satisfactory for my needs…
For now, what I get without changing many things in the first example given in
the manual, is quite close to what I would like to obtain, except that the
title of articles is in roman and the name of the journal is in italic, and the
title of books are in italic (and the modifications suggest by Alan do not
change this, at least when I am not using apa).
So my first question is: how can one define one's own « specification », when
modifying built-in specifications is not satisfactory for one's needs, or does
not give the expected result?
The second question is: how can one write a file containing only the references
which are used in a document, so that that file can be in some way included
into the main document (this is somewhat analogous to the .bbl file created by
BibTeX, which allows to include a series of \bibitem into an article written
with LaTeX: this is necessary to do when one submits a paper to a mathematical
journal).
Thanks again for your help: OK
%% begin test-bibliography.tex
\setupinteraction[state=start]
\usebtxdataset[test.bib]
%% these four setupbtx suggested by Alan have no effects
\setupbtx[list:volume][style={bold}]

The message was meant to be "don't abuse" markup in data;
Don't attempt bibtex/latex hackery.
As Hans mentions, \btxcommand was introduced to handle some formatting
in bibtex entries that might be inconsistent or in conflict with
standard ConTeXt commands. When no \btxcommand definition is found,
the system falls-back on standard ConTeXt (or luatex) syntax. Sloppy
bibtex files should be cleaned up, but the aim is to allow files to be
shared with bibtex/latex (minus any hackery, which could/should be
fixed in the bibtex style files, but usually is not).

Alan, I think this was Rik Kabel's point: for some scenarios, you
cannot avoid to have some sort of context commands in your bibtex

Indeed, that was my point. Even without the mathematics components that
were cited, I cannot imagine how markup could be excluded from the
BibTeX file, and for that matter, from any other bibliographical
database I have seen, if we have to comply with arbitrary formatting
standards. The statement that one should not put any such formatting
into the file is perhaps aspirational, but not really useful.
If you code clean it's no problem as we can map commands (\btxcommand)
but most (large) bibtex databases we've seen so far are quite
inconsistent (not only in usage of commands, also in author names).
(And of course Thomas meant Lua and not Perl.)

Even Computer Modern!
Do you mean to tell me that the TeX Gyre fonts are all "broken"?
And that the *only* correctly working font is ... Cambria?
So following up on the font discussion at the last ConTeXt meeting,
must we conclude that *all* of the fonts that we distribute with the
Standalone are to be avoided, and that one must pilfer the MicroSoft
font in order to typeset mathematics correctly?

Hi Fabrice,
the basic idea is the paper orientation matches the printing option (if
any).

\setupinteractionscreen[option=portrait] would be the right option here.
It is double-sided (duplex) printing for portrait orientation.
Consider that ConTeXt has \setuppapersize[A4, portrait] as default.
> - With the command \setuppapersize [A4, landscape] and without

You got two printed sheets instead of one. To get only one, you need to
specify duplex printing (as explained above). Otherwise, your printer
would print as its default properties specify.
There is even a \setupinteractionscreen[option=page] option, which
enables single-sided (or simplex) printing. This is required for
printers that are configured to print doublesided per default.

I hope it may be clearer after my explanation.

Sorry, but overflowing is normal here, the formula has too many data to
fit in that column width.
I would discourage the use of columns to create the booklet.
My advice would be to compose the standard text and then impose the pages:
\starttext
\dorecurse{4}{\chapter{Chapter \Romannumerals{\recurselevel}}
\section{\TeX}\input knuth\par
\section{Zapf}\input zapf\par
\section{Math}
\startformula
\startmathalignment[n=2,align={left,left}]
\NC P_1 + P_2 + \dots + P_{12} \NC = 400 + 400\times 1,05 +
400\times 1,05^2 + \dots + 400 \times 1,05^{11}\NR
\NC \NC = 400\times (1 + 1,05 + 1,05^2 + \dots + 1,05^{11})\NR
\NC \NC = 400\times \frac{1-1,05^{12}}{1-1,05}\approx 6\,367.\NR
\stopmathalignment
\stopformula}
\stoptext
And then use the following code with the output PDF document from the
code above:
\setuppapersize [A5][A4,landscape]
\setupexternalfigures[interaction=all]
\enabledirectives[references.border]
\setuparranging [2UP]
\setuplayout
[backspace=0pt,
topspace=0pt,
width=middle,
height=middle,
location=middle,
header=0pt,
footer=0pt]
\setupinteraction[state=start]
\setupinteractionscreen[option={landscape, fixed, paper}]
\starttext
\insertpages[document.pdf][width=0pt]
\stoptext
You should get something similar to the attached booklet.
Of course, you may have to increase font size in the original document.
But to know which increase in size the font needs, you have to check it
in the printed version of the final booklet.
With an already released booklet,
https://github.com/ousia/from-pandoc-to-context/blob/master/doc/from-pandoc-to-context_A4.pdf
is the basis to be imposed in the final booklet
https://github.com/ousia/from-pandoc-to-context/blob/master/doc/from-pandoc-to-context_A4-booklet.pdf.
The approach I’m suggesting is simpler and easier to implement.
Just in case it helps,
Pablo

Re: [NTG-context] Page printed upside down
Hi Pablo,
Sorry for the late response. I did some tests before answering to
understand your explanations.
- With the commands \ setuppapersize [A4, landscape] and \
setupinteractionscreen [option = landscape] and without selecting anything
in Acrobat, I get the desired double-sided document

without selecting anything in Acrobat, I get a document in double-sided

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

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

Dear Hans,
now, in luatex 1.05, that the primes are "constructed" in new

I tried

The pre-1.05 modification

(which is a non-optimal way of solving this issue since it has side

Hi,
should I interpret the silence that this is currently not possible, or
that you, Hans, is completely fed up with this subject? :-)
you rule out the possibility that i have other things to do

Re: [NTG-context] Bug regarding placement and size of primes
the alternative is that i waste time again and again on getting something to work for all fonts and all combinations which leads to a mess that i then need to maintain without any gainAt first: Thank you very much for your work!so, i decided to follow a route that works for most fonts / cases and not some messy hybrid solution (and i don't want a different setup or bag of tricks for each font that is out there as that is a long term no-go)But I have to contradict you here: It has nothing to do with special or hybrid fonts. The problem persists at present (using the LuaTeX version that is shipped with the Garden version) in all fonts. The primes are not rendered as they should in any font I tried out.As Mikael told me, you optimised the code for LuaTeX 1.05 which seems to be terminated September this year. But until then the output of primes will be not correct. I have no possibility to switch back to the current (non-beta) version of ConTeXt, because this version contains the bugs with primes you have already resolved.This means that ConTeXt is not usable for me until LuaTeX 1.05 will be released or until I am able to compile the source of LuaTeX 1.05 on my own. Some of the latest betas (the version one or two weeks ago) did solve all problems regarding primes. The problem I am referring to rose up in the most recent betas. As Mikael told me, this is because you introduced new code to work with LuaTeX 1.05. This is very nice, but because this version is not yet released, this decision is questionable, since this makes ConTeXt unusable until this release (if you need primes).So I appreciate your hard work, but I would be nice to have a version that runs with the current LuaTeX version of the beta of ConTeXt (or alternatively it would be nice if instructions are provided to compile the source of LuaTeX for every OS that can be used simply).And (to repeat myself) the problem has nothing to do with special fonts of hybrid version or whatever. You get the problem using standard Latin Modern or any font else. Simply try%%%\starttext%$f’$, $f^{''}$.%\stoptext%%%and you will get something like attached.BestMathias

Hans,
many thanks for your explanation, it is really appreciated when you
take your time to do this!
I updated my local lucida-opentype-math.lfg and indeed it works like
charm. I think the uncramped version I get now looks better than what
I forced with the temporary solution that I did not understand.

look at the output of (attached). In my opinion the first square root
is to "high", while it looks better on the second line. From
setup-en.pdf it looks like the default of \setupmathradical is set to
normal (and not default). I don't understand what normal should mean,
but I think the alternative=default looks better. (The lucida fonts
are loaded in this example, since the effect is more clear for them).
Ok, this is the story
-- radicals (roots) are rather special and have some hard coded
properties (like always scriptscript in the degree)
-- \over (and friends) that are used in \frac (which by the way can be
configured in many ways) has the danger of getting the wrong style as
side effect of parsing (math list construction) and processing
-- in context we want to support color etc for noth in a consistent way
as well as style control (important in educational math)
Normally it works out ok with the 'normal' setting but there is some
catch here. The size of the radical symbols is determine by
-- RadicalVerticalGap = 50
-- RadicalDisplayStyleVerticalGap = 175
(These are lucide values) and it happens that the second one if too
large which can give a bad threshold in our case. In cambria it's
RadicalVerticalGap = 166
RadicalDisplayStyleVerticalGap = 345
So a 1:2 ratio. If we use that for lucida it looks better, so
lucida-opentype-math.lfg
can become:
local function FixRadicalDisplayStyleVerticalGap(value,target,original)
local o = original.mathparameters.RadicalVerticalGap -- 50
return 2 * o * target.parameters.factor
end
return {
name = "lucida-opentype-math",
version = "1.00",
comment = "Goodies that complement lucida opentype.",
author = "Hans Hagen",
copyright = "ConTeXt development team",
mathematics = {
parameters = {
RadicalDisplayStyleVerticalGap =
FixRadicalDisplayStyleVerticalGap,
},
alternates = {
italic = { feature = 'ss01', value = 1, comment =
"Mathematical Alternative Lowercase Italic" },
arrow= { feature = 'ss02', value = 1, comment =
"Mathematical Alternative Smaller Arrows" },
operator = { feature = 'ss03', value = 1, comment =
"Mathematical Alternative Smaller Operators" },
calligraphic = { feature = 'ss04', value = 1, comment =
"Mathematical Alternative Calligraphic Characters" },
zero = { feature = 'ss05', value = 1, comment =
"Mathematical Alternative Zero" },
partial = { feature = 'ss20', value = 1, comment =
"Mathematical Alternative Upright Partial Differential" },
},
},
}
It's sort of a font property: the more sizes the better and sometimes
you're simply hit by the threshold not suiting your case.

Thank you Hans, that works.
Is there also a similar way to use the "kernpairs" instead of "kerns"?
I get no effect, even after adding force = true and
\enabledirectives[fontgoodies.mathkerning].

Now that the bug with primes is fixed in ConTeXt, I wonder if there is
a way to change the kerning between certain characters in mathematics
(in case one is not happy with the output from the font)? After

you can also play withj:
return {
name = "cambria-math",
mathematics = {
kerns = {

force = true,
topright = {
{
kern = 1000,

bottomright = {
{

},

currently you need to enable this:
\enabledirectives[fontgoodies.mathkerning]
keep in mind that some cambria (not all) have such staircase kerns which
is why force is needed in order to overload
\startluacode
fonts.handlers.otf.addfeature {
name = "kerntest",
type = "kern",
data = {
[0x61] = { [0x62] = -150 }, -- a and b in text
[0x1d44e] = { [0x1d44f] = -150 }, -- mathematical italic small a and b
[0x02032] = { [0x00028] = -150 }, -- prime and left parenthesis
}
}
\stopluacode
\definefontfeature[kerntest][kerntest=yes]
\definefontfamily[lucidaopentype][rm][Lucida Bright OT]
\definefontfamily[lucidaopentype][mm][Lucida Bright Math OT]
\setupbodyfont[lucidaopentype,10pt]
\startTEXpage[offset=3pt]
abba $abba f'(x)$
\addff{kerntest}
abba $abba f'(x)$
I prefer $f'\mkern-3mu(x)$
\stopTEXpage
The output is attached as a png file. As you see the kerning works as
expected in text mode, but not at all in math mode, even not for the a
and b (which I hope I entered correctly).
Something like the third line is what I'm after, but not having to use
\mkern in all places. Is it possible?

Thank you very much for your reply, Mathias!
I'm not sure I get it, though. I find that there is already a file
lucida-opentype-math.lfg in the distribution.
Just experimenting, I added to this file an entry with kernpairs (see
below), to see if I could make a change with a and b (if I cannot
manage that, I don't see how I could get the prime and parenthesis
case to work).
%%% start of my new lucida-opentype-math.lfg
- kern_250 = { bottomright = { { kern = -250 } }, force = true }
return {
name = "lucida-opentype-math",
version = "1.00",
comment = "Goodies that complement lucida opentype.",
author = "Hans Hagen",
copyright = "ConTeXt development team",
mathematics = {
alternates = {
italic = { feature = 'ss01', value = 1, comment =
"Mathematical Alternative Lowercase Italic" },
arrow= { feature = 'ss02', value = 1, comment =
"Mathematical Alternative Smaller Arrows" },
operator = { feature = 'ss03&#
Re: [NTG-context] Change kerning between math characters (prime and left parenthesis)
Hi Mikael,
math fonts are a bit different from text fonts. This means that you need
special methods to influence them. Because I once had a similar concern like
you I asked Hans to implement a way to influence kerning in math fonts between
certain glyphs. I have attached an lfg-file that shows how to use it.
To enable a goodie file like the one attached you have to define your
typescript like
\starttypescript [\s!math][cambriaown][\s!all]
\loadfontgoodies[cambriaown-math]
\definefontsynonym[\s!MathRoman][Cambria-Math]
[\s!features={\s!math\mathsizesuffix},\s!designsize=\s!auto,\s!goodies=cambriaown-math]
\stoptypescript
I hope this helps!
Best
Mathias

[NTG-context] Change kerning between math characters (prime and left parenthesis)
Hi!
Now that the bug with primes is fixed in ConTeXt, I wonder if there is
a way to change the kerning between certain characters in mathematics
(in case one is not happy with the output from the font)? After
reading in fonts-mkiv.pdf this is what I came up with:
\startluacode
fonts.handlers.otf.addfeature {
name = "kerntest",
type = "kern",
data = {
[0x61] = { [0x62] = -150 }, -- a and b in text
[0x1d44e] = { [0x1d44f] = -150 }, -- mathematical italic small a and b
[0x02032] = { [0x00028] = -150 }, -- prime and left parenthesis
}
}
\stopluacode
\definefontfeature[kerntest][kerntest=yes]
\definefontfamily[lucidaopentype][rm][Lucida Bright OT]
\definefontfamily[lucidaopentype][mm][Lucida Bright Math OT]
\setupbodyfont[lucidaopentype,10pt]
\startTEXpage[offset=3pt]
abba $abba f'(x)$
\addff{kerntest}
abba $abba f'(x)$
I prefer $f'\mkern-3mu(x)$
\stopTEXpage
The output is attached as a png file. As you see the kerning works as
expected in text mode, but not at all in math mode, even not for the a
and b (which I hope I entered correctly).
Something like the third line is what I'm after, but not having to use
\mkern in all places. Is it possible?
/Mikael
