[NTG-context] \intertext and highlighting with \alignhere/\breakhere
Hi all,
Often I want to include a sentence/paragraph in the middle of a long
multipart formula. With the old \startalign/\stopalign formulas, I could
use \intertext{...} to do this, but this doesn't work with the new
\alignhere/\breakhere formulas. I've managed to find a "solution" for
this, although I'd prefer something a bit less hacky. Any ideas?
Also, is there a way to highlight an equation across an \alignhere? Once
again, I've found a "solution", but like before, it's pretty hacky.
Example files are attached.
Thanks,

[NTG-context] Re: manuals
Hello everyone! As an eternal newbie (with a memory like a goldfish), I started by building my own documentation from the web pages constructed by Bertrand Masson (prehistory archaeologist in Northern France) "les fiches à Bébert" (obsolete version here: http://bertrandmasson.free.fr/; new recommended version here: http://lesfichesabebert.fr/TeX/context/context-intro.html). As mentionned by Alain Delmotte. Bertrand Masson always keeps his site up to date, as he gives references to the documentation compiled by Garulfo (Joaquín Ataz López ), available in several languages, which I personally found well-done, useful and welcome. It's interesting to note with a rather positive smile that documentations, even if they're never really up to date in the details of ConTeXt's evolution, copy each other: that's what I did to write the beginning of a Wikibook in French (https://fr.wikibooks.org/wiki/ConTeXt/Qu%27est-ce_que_ConTeXt_%3F). I took things written by Bertrand Masson and was partially taken over by Garulfo and so on. Fortunately, the ConTeXT discussion list offers MWEs: all you have to do is to test them and save these examples on your system in the CTX-TESTS document folder. The next step is to classify these examples under the appropriate headings, then insert them into a coding system for a complex document that always calls for requests for explanations from discussion list participants. This question of documentation seems to me to be an age-old snake, not only on a technical subject which can be complex, as ConTeXt can be, but also concerning other types of documentation. For my part, although I haven't yet exhausted all the available documentation resources, whether internal to the distribution, or online like the ConTeXt Garden wiki, I think (but this has been better expressed here by others than me) that a real documentation refresh could be carried out collectively, with the great ambition of keeping obsolete documentation in an archive, while proposing a wiki with the date of update visible, in correlation with the PDF version. I have no idea how this documentation update could be achieved, but the fact is that it would be desirable to devote a section to the purely technical and basic aspects of CTX installation and font availability on Windows, Mac OS, Linux, BSD, etc., with MWEs and examples a little more detailed. Once this documentation has been passed as an introductory part (itself containing chapters explaining how this page of documentation was put together, with notes in the margins, etc.), this book could introduce MKIV, LuaTeX, MetaPost and so on, but with a clear distinction between the objectives sought: writing documentation with figures, writing a thesis in mathematics and physics, how to construct figures, or a bibliography. Not to mention the handling of photographs in an aesthetically demanding layout; all this with the possibility of showing complete or partial examples of work produced... In a nutshell: even if I give the impression that I'm asking you to reinvent the wheel, in reality it's a question of collating relevant existing information in a way that is intelligible and clear to the neophyte, but that also meets the demands of experienced users, who don't all use ConTeXt for the same reasons. Don't get me wrong: I'm not telling you what to do, I'm just giving you my opinion. Basically, I'm saying: documentation exists, but it has to be reliable, up to date, easy to find and enable you to make progress in difficult situations. As I said, I found Garulfo's work very welcome. It's not obsolete and doesn't need replacing. But perhaps it could be amended on certain points and completed and made available both in PDF and online in the ConTeXt Garden wiki pages? So, if by hypothesis the relevant documentation exists, here and there, but it's in the middle of pages that are in the past, it can be considered a daunting task to go looking for information that you realize is no longer up to date, because experience shows that it's no longer reliable. If confusion reigns, those seeking to apply what they've read risk turning away from ConTeXt, or asking the same questions over and over again. So there's plenty of food for thought to be had when it comes to methods for overhauling existing documentation. It's not a question of thinking long and hard about the availability of this documentation (on line or as a PDF?), but rather of knowing whether to build an encyclopedia, or a series of manuals, each of which is intended to circumscribe as closely as possible the problems encountered when attempting this or that form of page layout. I remember being astonished to discover, when I first started learning ConTeXt, all the vocabulary that existed around page layout (in French: Grand fond, petit fond, blanc de tête, blanc de pied, etc.), vocabulary that we ignore when we come from Word office autom

I also use fractions frequently, so I’ve tried a few things.
Some fonts have superior and inferior numbers that can be used to make small
slash fractions. I’ve done this, but my method is not pretty. Hraban suggested
using font features for this, but I haven’t learned how to do that. Any advice
is welcome.
Example code below uses the Libertinus font, which has these superior and
inferior numbers, to produce sample paragraph demonstrating a few options for
fractions in text.
Gavin
\usetypescriptfile[libertinus]
\setupbodyfont [libertinus,11pt]%
\setupinterlinespace[line=3.1ex]
\define\fracone{\getnamedglyphdirect{libertinus}{onesuperior}} % 1
\define\fracthree{\getnamedglyphdirect{libertinus}{threesuperior}} % 3
\define\fracnine{\getnamedglyphdirect{libertinus}{ninesuperior}} % 9
\define\thirteenths{\textfraction\getnamedglyphdirect{libertinus}{oneinferior}\getnamedglyphdirect{libertinus}{threeinferior}}
% /13
\define\onethirteenth{\text{\fracone\thirteenths}} % 1/13
\define\threethirteenths{\text{\fracthree\thirteenths}} % 3/13
\define\ninethirteenths{\text{\fracnine\thirteenths}} % 9/13
\starttext
Some small fractions are already available in many fonts, like \onehalf\ and
\onethird. Others can be built using superior and inferior numbers in some
fonts. This includes the fractions required to
find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\threethirteenths}$, $m=\sqrt{\onethirteenth}$, and
$n=\sqrt{\ninethirteenths}$.
Of course, you could just find the normal and shearing stresses on an oblique
plane defined by $l=\sqrt{3/13}$, $m=\sqrt{1/13}$, and $n=\sqrt{9/13}$.
Vulgar fractions are between these extremes.
Find the normal and shearing stresses on an oblique plane defined by
$l=\sqrt{\vfrac{3}{13}}$, $m=\sqrt{\vfrac{1}{13}}$, and
$n=\sqrt{\vfrac{9}{13}}$.
I included more text than strictly necessary in this example to demonstrate the
effect on line spacing.

I usually only need simple inline fractions like 1/n, 1/2 or 3/8 in text.
With these and \frac, the spacing below the numerator (depth) is too
big, while the denominator sticks too tightly to the fraction bar.
(Of course I use regular numbers for fractions, not mediaeval.)
Usually I’d prefer “vulgar fractions”, but \vulgarfraction looks
“horrible” in comparison to the few usual fractions contained in fonts
(like ½ & ¾).
I tried to use the OpenType fraction features to no avail.
So I’m still looking for “the best” solution for simple fractions inline.

[NTG-context] Several math features broke for me in new Debian version
Dear Friends,
I am a regular user of ConTeXt. A recent upgrade of ConTeXt in Debian
broke things for me. The bug report is here:
https://bugs.debian.org/1055233
but I have reproduced the gist here:
Upon upgrading to ConTeXt 2023.05.05.20230730+dfsg-2, several math
features seem to break for me. Here is an example:
\starttext

\startformula
X(f) = \startcases[align={right,left},distance=3pt]
\NC T, \NC{} $|f| < \frac{1}{2T}$ \NR
\NC 0, \NC{} $|f| \geq \frac{1}{2T}$ \NR
\stopcases
\stopformula
\stoptext
The above works very well in 2021.03.05.20230120+dfsg-1+deb12u1 but
gives me this error in 2023.05.05.20230730+dfsg-2:

Design sizes for typefaces -- aka "optical sizes" -- are no longer directly

You can still do it but for all these years only cm has design sizes so
one can wonder.
Hm.. There are a few others, Minion perhaps being the most popular and
extensive. More below:
"at some point the decision was made to kick out these definitions and move the
burden of figuring out the right size to Lua."
They were moved to the goodie file (there are every few design size
setups in goodie files, minion has one, but i don't have these fonts nor
use them.
Have just completed a minion-pro-opticals typescript collection with a
minion-opticalsizes.lfg.
Somehow I didn't even see yours and Mathias' minion.lfg (and associated
type-imp-minion) until just now, had to figure it all out from scratch from
demo.lfg and lm.lfg templates -)
(OTOH, had previously seen yours and Mikael's sophisticated minion-math.lfg)
I think that my version is/will be more complete - except for mathematics. Once
some fine-tuning and additional testing is done, will donate the results to
ConTeXt.
(Thus some large typescript collections painstakingly built over the years are
now obsolete and have to be rewritten. Oh well..)
Well, i suppose one can still setup/use the typescripts but it's less
fun. The old definefont mechanism is still there.
Unfortunately it doesn't work anymore - or at least not the way it used to. My
mkiv minion typescript collection, for example, still compiles in lmtx, but the
design sizes do not show up in the output anymore, only the default size.
As a side note: we have design sizes (very few fonts) and weights (more
and more fonts) .. weights are imo an even bigger mess, as it looks like
some designers can't make up their mind and come with plenty weights
independent of the fact that some look bad; variable fonts only add to
this: the easier to use the creater tools become the easier it becomes
to make ugly fonts (I tend to ignore fonts that show off too many
possible choices; not much different from excessive kerning, ligatures
and other incomplete features).
You make an important point, especially about the proliferation of bad fonts
via more accessible tools. On a related front, there are more and more
Arabic-script fonts, but hardly anything really good or useable, even from
reputable foundries like Adobe. At some point, presumably, designers quit early
(or the company does not care to invest the needed time and funds).
Presumably, designing good optical sizes requires more care and subtlety than
designing weights.
OTOH the more professional/high-end foundries sometimes recommend certain
weights for optical-sizes. For example, your neighbors at Enschede:
http://www.teff.nl/fonts/geronimo/
"While Geronimo was mainly conceived as a typeface for (small) text, it also
performs well at bigger sizes most notably the lighter weights.”"
There are 12 weights total (six regular + six italic), but the lighter weights
are designed to work well at larger sizes. So from 12 fonts one can create a
reasonable, combined optical-size and weight space.
(Speaking of Enschede, their Lexicon typeface use an interesting/unique
optical-size concept.)
One thing about the explosion of weights is that the distinction between \tf
and \bf (or \it and \bi) vanishes and becomes a spectrum. In that case,
presumably one would
i) forget about \bf and \bi
ii) multiply bodyfont-typefaces and switch directly between them as needed.
Etc.
If this appearance of a loss reflects the reality of the situation, would like
to kindly request that the original functionality be restored to the
higher-level user interface, presumably within the lfg file. So perhaps
something like a keyval
fallbacks = {
["MyRomanRegular"] = {
"file:MyFont-Small" = "fallbacks=",
"file:MyFont-Regular", = "fallbacks=",
"file:MyFont-Bigger", = "fallbacks=",
"file:MyFont-Biggest", = "fallbacks=",
},
On the other hand, if access to the former functionality is still there
somewhere in the user interface, would like to humbly request that someone
share where it is and how to use it!
Thank you kindly for consideration of this request.
I'm not going to look into this until there is a complete test case for
this which means:
- free fonts (so that others can also test and use)
- design sizes
- fallback design sizes
As for free fonts. MinionPro Opticals should be considered an exception to the
free-fonts rubric. After all,
i) its multiple-master design base was inspired by MetaFont/Knuth, and hence
ii) it's very popular with TeXies.
Put another way, Minion Pro should be considered an honorary TeX typeface -)

[NTG-context] Re: Nested itemize
It seems that displaystyle fractions insert extra vertical space before the
main item.
With textstyle fractions, the code works fine.
\blank[back,overlay] can get rid of the gap above the first row, but not
the space inserted by \dfrac.

Not really tested, but \blank[overlay,-depth] seems to work OK (thanks Hans!).
I also take the opportunity to push a bit for the new itemtable mechanism:
\defineitemgroup[alex]
\setupitemgroup
[alex]
[each]
[a,two]
[margin=2cm,
before=\blank[overlay,-depth]]
\showboxes
\starttext
\startitemize[n]
\startitem
\startalextable
\startitem First \stopitem
\startitem Second \stopitem
\startitem Third \stopitem
\startitem Fourth \stopitem
\stopalextable
\stopitem
\stopitemize
\stoptext
Please test for a larger document to see if it works well.

[NTG-context] Re: Nested itemize
I'd do it this way:
\starttext
\startitemize[n][style=\bf]
\item\vtop{%
\startitemize[a,horizontal,four][stopper=\)]
\startitem
$6(x - \dfrac{5}{12})^2 - \dfrac{1}{24}$
\stopitem
\startitem
$-3(x - \dfrac{1}{3})^2 + \dfrac{1}{3}$
\stopitem
\startitem
$7(x + \dfrac{5}{14})^2 + \dfrac{199}{28}$
\stopitem
\startitem
$-\dfrac{1}{2}(x + 2)^2 + \dfrac{9}{2}$
\stopitem
\stopitemize
}
\stopitemize

[NTG-context] Re: Nested itemize
Dear ConTeXt users,
Time goes by but I haven't yet found a nice solution to this issue. When
having mathematics, I'd not like to adjust by hand the factor of \linewidth
for the \godown command.
Here's a MWE
\starttext
\startitemize[n][style=\bf]
\item \godown[-\lineheight] \startitemize
[a,columns,four,packed,broad][stopper=),before={\blank[nowhite]}]
\item $6(x - \dfrac{5}{12})^2 - \dfrac{1}{24}$
\item $-3(x - \dfrac{1}{3})^2 + \dfrac{1}{3}$
\item $7(x + \dfrac{5}{14})^2 + \dfrac{199}{28}$
\item $-\dfrac{1}{2}(x + 2)^2 + \dfrac{9}{2}$
\stopitemize

Thanks in advance.

So, the problem is not the package or the distro, it's something more basic
which causes the error.

[NTG-context] tikz error upgrading to texlive version (artix)

I use artix linux (a fork of arch with systemd alternative init systems).
During the texlive package, I get this error:

I simply run context to this file:

I tried using \mathboxanchored, and was able to get the bottom two equations
shown here. (The top equation uses \hpos, for comparison.)
mathboxanchored.pdf
Description: Adobe PDF document
There are two problems that I didn’t know how to fix.
1) The line connects to the box including the subscript or superscript, not
just to the e.
2) I cannot make multiple connections to a single object, like the e^\mu in the
center. If I try to connect top and bottom, I get no connections anywhere in
the entire document.
The code for the formulas is:
\startformula
% Each \connectboxanchors works alone, but both together make trouble:
\connectboxanchors[top][top]{X}{Y}
%\connectboxanchors[bottom][bottom]{Y}{Z}
\mathboxanchored{X}{e}_\alpha \mathboxanchored{Y}{e}^\mu
\mathboxanchored{Z}{e}_{\dot\beta}
= \textfrac{1}{\sqrt{2}}\sigma_{\alpha\dot\beta}^\mu
\stopformula
I added code to turn the arrow produced by \connectboxanchors into my
contraction overlay, but that doesn’t affect these issues.

Yes, we only need to anchor to e.

This could turn into a book length project, with several formulas per page and
several connections per formula. If every \hpos in the entire book needs a
unique identifier, I could go mad. Under no circumstances will I connect one
formula to another, so I’d like to be able to use something like
\hpos{A}{…}…\hpos{B}{…} in each formula. Any suggestions?
one problem is (and i'm working on that) that one could want multiple
anchors on a math atom as well as pu tit on the nuclues only
I’ve got to say, LMTX is an absolutely amazing tool for this project, which
includes complicated networks of connections above and below many formulas. The
integration of TeX, MetaPost, and Lua makes this project tremendous fun.
that's the idea
P.S. For the curious, I’m using a method for doing General Relativity based on
spinors rather than tensors, following the methods of Penrose and Rindler in
their 1985 books “Spinors and Space-time.” In the typesetting example above,
the e_\alpha and e_{\dot\beta} are basis spinors (one left-handed, one
right-handed). The e^\mu is the Infeld-van der Waerden symbol relating the spin
basis to the coordinate basis. The connections are spinor index contractions.
The formula above relates the components of the Infeld-van der Waerden symbol
to the Pauli sigma matrices. This relationship only works in flat space, so
this is an easy example! [Penrose and Rindler, vol 1 p. 125]
in your example we need a way to anchor on just the 'e' right? or do you
want it on the e + super/subscript?

I will wait for the manual. With drawing commutative diagrams, I am sure
learning how to use MetaFun/MetaPost better might help.

Hi,
I uploaded a new version of lmtx (also because some users have to test
some new metapost functionality). In the next upload metafun will use
'double' mode (and scaledfun will be the traditional one). The
advantage is less dager for overflows and in the meantime running in
double mode is often also faster.

along with the bibtex file (refs.bib attached here), only the second citation
entry has a properly rendered bibliography entry while the first one does not.
Notably, any bibtex entries whose tags are not all lowercase (ASCII) are not
rendered correctly. Instead, in the log I get
publications > unknown tag 'nielsen2011_chernoffinformationexponentialfamilies'
in dataset 'default'
Almost all my entries in bib files are in camel-case since I find that to be
easier to read and it gives me a better clue of what the item is. With some
recent uploads I noticed that in publ-ini.lua 'tag' and 'field' entries were
string.lowered(). Upon removing those statements, I am able to get the proper
output.
I also have certain bib files where the entries are not at all in ASCII (so I
am not sure what the code might do there, I did not check in detail). I hope I
can continue to use camel case for the tags (if its not too much to ask): is
there some additional setting that I should change to allow this so that the
output is rendered correctly?

Re: [NTG-context] OT world history: other measuring systems?
As you know, there were very variable measurement systems in Europe after the fall of the Roman Empire, depending on the region within the same country. It is difficult to say precisely why political unity, when there was one in a given country, did not make it possible to systematize the use of the same standard of measurement throughout the country, because it is quite astonishing to see that the cubit, the foot, the pound etc. vary from one region to another during the medieval period. The answer to this question on the variability and versatility of measures is undoubtedly due to the fact that the birth of modern nations has been accompanied by the emergence of a rational State which has increasingly taken the place of a rational administration (legal) of social relationship. The French Revolution of 1789 carried out the efforts at rationalization that we had seen develop with the appearance of a strong State from the end of the wars of religion and the reign of Louis XIV in France: the metric system (based on a segment of the Greenwich meridian) in base 10, makes it possible to obtain measurements of surfaces, distances and volumes which are the same everywhere and which do not vary according to whether one is in Normandy, Lorraine or Provence. For those interested in the point Didot (the printing point under the French monarchy), its value was 1/72 of a foot (of the king's foot)... which king's foot could not be a foot of English king, nor a symbolic value as guinea was ! see here : https://en.wikipedia.org/wiki/Units_of_measurement_in_France and here : https://en.wikipedia.org/wiki/Units_of_measurement_in_France_before_the_French_Revolution Le 25/01/2022 à 20:28, Henning Hraban Ramm via ntg-context a écrit : Am 25.01.22 um 18:27 schrieb Aditya Mahajan: On Tue, 25 Jan 2022, Henning Hraban Ramm via ntg-context wrote: why didn’t "we" stick to the Roman system?

Re: [NTG-context] Critical Editions?
Thank you Luigi ! "Quite old" doesn't matter. The date of the wiki page from Thomas is 2010... And my own contribution to first steps with ConTeXt (in French and not for mathematics) through a Wikibook is no more valuable, full of errors and obsolete on many aspects (https://fr.wikibooks.org/wiki/ConTeXt) ! As Garulfo made a quite good job last year with his own contribution (https://github.com/contextgarden/not-so-short-introduction-to-context/tree/main/), it may be useful to produce a kind of "howto" with TEI-XML and LMTX-CTX. I propose that at first time, any volunteer gather documentation on TEI-XML with ConTeXt to feed the wiki page on this topic, with in mind a real case of their choice (which may be a real academic case or an issue of their choice), not too tricky - or too far away of the common use, even if, by itself, the issues encountered in academic edition in humanities (or TEI-XML edition) are ... tricky and/or not very usual (because not it is not everybody who try to edit the work of Romanos the Melodist, or sanskrit poetry !). As I saw that Thomas A. Schmitz was time to time an editor of Second Sophistic authors (among other things like French Renaissance poets), and few others Context users use to deal with CTX in order to publish ancients texts/poetry (like Pablo ...), I propose in a second time a general discussion on the topic, with in mind : What are the needs ? and what it is necessary to achieve at first and how ?

I have been using ConTeXt to typeset documents in several Indic languages and have run into similar issues (in many languages). Please see this for a similar issue in some conjuncts for Devanagari: https://www.mail-archive.com/ntg-context@ntg.nl/msg99691.html For what its worth, I have not had issues with some fonts while issues with others persist. Some of these issues we can work around as I have pointed out in the above posting. In almost all cases I encountered no issues while using Xe(La)Tex. Based on some advise from Hans and reading about these OTF features and their implementations in Indic fonts, I think these issues might be due to differences in implementation. [Not entirely sure since I am a novice]. My guess is that Harfbuzz (which is what Xe(La)TeX uses by default) uses some heuristics to work out these conjuncts (?!). To answer your specific question regarding the conjuncts in the given words you have to use some Unicode hacking to get what you want in ConTeXt. In each of the following ZWS refers to the Unicode character (zero-width space U+200B) 1. ശ്രീ This is typeset correctly by writing ശ്ര + ZWS (U+200B) + ീ 2. അശ്രു Typeset correctly with അശ്ര + ZWS (U+200B) + ൂ 3. ശുശ്രൂഷ Typeset correctly with ശുശ്ര + ZWS (U+200B) + ൂ + ഷ 4. പ്രാസം Typeset correctly with പ്ര + ZWS (U+200B) + ാ + സം 5. പ്രേയസി (rendered correctly as entered; no hacks necessary) 6. പ്രോഗ്രാം Typeset correctly with പ്രൊ + ഗ്ര + ZWS (U+200B) + ാ + ം where the last character is the Malayalam Anusvara. Consider yet another example: സാന്ദ്രാനന്ദാഅവബൊധാത്മകമ് Here the 'ന്ദ്രാ' conjunct is not typeset in ConTeXt. To fix this I do ന്ദ്ര + ZWS (U+200B) + ാ This is what I have been doing to ensure correct typesetting of Malayalam and other Indic languages in ConTeXt. Honestly, it is inconvenient since the .tex files containing Unicode are no longer sanitary. However, ConTeXt has so many remarkable features that the very thought of having to go back to (Xe)LaTeX (just for harfbuzz rendering) causes me immense pain. As far as I am concerned, in every other way ConTeXt simply has no match in the (Xe)LaTeX world. In my usage of ConTeXt for my academic work (in English with lots of mathematics) I have encountered no issues. Even if I did there was always some legitimate (non-hacky) fix for it. For me personally, the rendering in Indic languages is the only pain point with ConTeXt (which I am willing to live with). So I am willing to live with the drawbacks till the day they are hopefully fixed. Anyway, I hope you can use these fixes temporarily. For example, if your editor supports it, you can replace all glyphs with this issue with the corresponding recipe involving ZWS. Dear Hans and other developers of ConTeXt, LuaTeX, If you happen to see this please look into the font system (where it concerns Indic systems). The present issue is very similar to the one I posted about earlier: https://www.mail-archive.com/ntg-context@ntg.nl/msg99691.html I have described the issue and the hacks to fix it the best I can.

[NTG-context] Math in LMTX and definemathcommand
Hi Hans,
Thank you for the new upload and the rewriting of the math fonts stuff, thanks
also to Mikael S. I did several tests on real size math projects and did not
notice important issues.
The two issues I noticed, show up mainly with LucidaOT, and are explained in
the following example:
\setupbodyfont[lucidaot]
\definemathstackers[MySymbol]
[voffset=-1.4\mathexheight, % -.8\mathexheight
hoffset=\zeropoint,
mathclass=ord,
topoffset=.3\mathemwidth, % poor man's italic correction
middlecommand=\mathematics]
\define[1]\interior{\mathover[MySymbol]{176}{#1}} %2218 U+00B0
\definemathcommand [Argmin] [limop] {\mfunctionlabeltext{ArgMin}}
\definemathcommand [liminfbar] [limop] {\underline{\mfunctionlabeltext{lim}}}
\definemathcommand [limsupbar] [limop] {\overline{\mfunctionlabeltext{lim}}}
\starttext
If $A \subset {\Bbb R}$ is a set, its interior is denoted by $\interior{A}$.
Can one have the circle over $A$ slightly bigger (probbaly this is font
dependent)?
The built-in commands $\liminf$ and $\limsup$ do not work properly with
LucidaOT (I tried other fonts and there they are fine):
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminf_{n \geq 0}x_{n} = -1, \quad
\limsup_{n\geq 0} x_{n}= +1.
\stopformula
The commands defined above, \type{\liminfbar} and \type{\limsupbar}, behave
correctly in all fonts I tested:
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminfbar_{n \geq 0}x_{n} = -1, \quad
\limsupbar_{n\geq 0}x_{n} = +1,
\stopformula
but not the command \type{\Argmin} (which does not show Argmin in any font…)
\startformula
\Argmin_{x\in {\Bbb R}} (x^2 - x + 1) = {1 \over 2}.
\stopformula

[NTG-context] Incorrect rendering in Devanagari forms in some fonts
Dear All, I have encountered a strange problem using certain Devanagari fonts for the Sanskrit languagein ConTeXt, wherein the rakaar ligatures are not rendered properly in some glyphs/conjuncts. The problem is not too easy to describe so please pardon this long email. The fonts I am using are as follows: • Shobhika – https://github.com/Sandhi-IITBombay/Shobhika • Murty Sanskrit – https://murtylibrary.com/mcli-fonts.php I had previously posted about this issue on TeX SE and Ulrike Fischer was kind enough to suggest that the problem might have something to do with the font rendering (since I have no issues in XeLaTeX (using Harfbuzz)): https://tex.stackexchange.com/questions/612634/devanagari-forms-in-context-using-shobhika-font My ConTeXt (LMTX) version is: 2021.08.30 19:56 I am using the following typescript for Murty: \starttypescript [serif] [murty] \definefontsynonym [Serif] [name:murtysanskritregular] [features=devanagari-two] \stoptypescript \starttypescript [murty] \definetypeface [murty] [rm] [serif] [murty] [default] \stoptypescript and the following for Shobhika: \starttypescript [serif] [shobhika] \definefontsynonym [Serif] [name:shobhikaregular] [features=devanagari-two] \definefontsynonym [SerifBold] [name:shobhikabold] [features=devanagari-two] \stoptypescript \starttypescript [shobhika] \definetypeface [shobhika] [rm] [serif] [shobhika] \stoptypescript Below is the test file I am using to demonstrate the problem: \setupbodyfont[shobhika] \starttext \startcolumns ट्रा ट्रि ट्री ट्रु द्रू ट्रे ट्रै ट्रो ट्रौ ठ्रा ठ्रि ठ्री ठ्रु ठ्रू ठ्रे ठ्रै ठ्रो ठ्रौ ड्रा ड्रि ड्री ड्रु ड्रू ड्रे ड्रै ड्रो ड्रौ ढ्रा ढ्रि ढ्री ढ्रु ढ्रू ढ्रे ढ्रै ढ्रो ढ्रौ छ्रा छ्रि छ्री छ्रु छ्रू छ्रे छ्रै छ्रो छ्रौ \column क्र ख्र ग्र घ्र ण्र च्र छ्र ज्र झ्र ञ्र च्रे छ्रे ज्रे झ्रे ञ्रे त्रे थ्रे द्रे ध्रे न्रे प्र फ्र ब्र भ्र म्र य्र ल्र व्र स्र श्र ष्र ह्र \stopcolumns \stoptext When I use the 'devanagari-two' feature set, which sets the script tag to 'dev2', the rakaar forms (provided by the features 'rkrf=yes' and 'blwf=yes') do not render properly for some glyphs, namely the glyphs in the right column, enclosed in a red rectangle in the file 'devanagari-two-forms-shobhika.png' attached in the Drive folder here. When I switch to using the 'devanagari-one' feature set (in the foregoing typescript definitions), which sets the script tag to 'deva', the rakaar forms in the left column are rendered incorrectly in the file 'devanagari-one-forms-shobhika.png' attached in the Drive folder here. Analogous problems occur with the Murty font. Further, in the Murty font, one other conjunct, namely त् + त does not render properly. I have highlighted this in the file 'murty-conjuct.png'. The sample images demonstrating the issues are available in the following public Google Drive folder: https://drive.google.com/drive/folders/1aOmPKqBzB5usVvT9g-Bxk87exyiQn7ax I must mention once again that I have no such problems using either of these fonts in XeLaTeX. What I am noticing is that this problem only occurs with consonant forms that have a 'circular base', i.e., have no danda (the vertical line) next to the character. For what it is worth, I have noticed also that I am able to 'circumvent' this issue if I write छ्र + ZWS + Devanagari vowel sign where ZWS is the zero-width space U+200B. Unfortunately, this quickly becomes very untenable in large documents. Since I was new to ConTeXt I did not venture to ask earlier on since I had not read much of the documentaion. Now, after having read quite a bit, I have mustered up the courage to ask here. As a stop-gap solution, I defined another font alternative with \definefontalternative[rk] and used that with a font synonym using 'devanagari-two' where necessary. I have completely migrated (away from (Xe)LaTeX )to ConTeXt for all my university work which is in English with lots of mathematics. I am by no means an expert but I have learned very much about ConTeXt by reading the excellent wiki, documentation and mailing list. I have no issues using ConTeXt on an everyday basis for my English-language based work. It is only when I tried to use it for my work in Indian-languages that I ran into this issue. I request your kind help in this matter. I really want to be able to use ConTeXt for these Indic works. I will be grateful for any help and/or guidance.

If you happen to use ibus on a linux, there's a emoji/unicode picker <https://mike-fabian.github.io/ibus-typing-booster/documentation.html#emoji-predictions>, where you can type `elem` and pick one from the candidates “∈∉∊⋲⋳⋴⋵⋶⋷⋸⋹⟒⫙” .

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.

There is no recommended way. One can have it in the input sources. The quickest way to both design and use I have found is text substitutions [1].

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,

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.)

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?

Hi Julian,
The tilde ~ in {\bf\ss #1.~#2} is only there to have an unbreakable fixed space

one can see that one has put a space there… :-)

Still off list. You are very patient but also very thorough, and this is making
a huge difference to what is in fact a considerable challenge for me, but one I
am coming to grips with. I believe this aspect of things is now clear to me. No
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
moment, which means I'll need either some understanding or some tweaking, but
as always there are people on the list like yourself who are prompt with their
assistance.
Kind regards,

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]
\definefontfamily [mainface] [mm] [alegreya]
\definefontfamily [mychapterfont] [ss] [itcavantgardepromd]
[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]
I think the problem is that if I define two or more \setupbodyfont items, it is
the last
[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?
Thanks in advance: Otared

[...,

1. \symbol is meant to access pre defined symbols, as fallback method
when the requested symbol doesn't exist ConTeXt outputs the argument.
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
in the math formula to avoid the vertical space between them, you can
remove it but I would at leas use \blank[back] to get rid of the empty

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

i'm still exploring this but it has to do with collecting stuff, as in:

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!

[NTG-context] Converting from LaTeX for PDF accessibility tagging?
Hello, I tried ConTeXt a few years ago, then gave up on it because of its wordiness and verbosity. The 2006 article on creating AMSTeX output in ConTeXt at https://www.ntg.nl/maps/34/06.pdf shows exactly what I mean: the LaTeX commands are small and neat; the ConTeXt commands are not. However, I need now to use ConTeXt for accessibility tagging, so I'm prepared to give it another try. And this means converting some LaTeX documents into ConTeXt. Is there a better way than using pandoc? I ran a LaTeX document through pandoc, but the result is certainly not fully "ConTeXt compliant", and generates errors instead of compiling. I can get easily lost on the ConTeXt site: the documentation is there in plenty, but seems hard to search. The main problem for me is mathematics and alignment: not just for equations, but for matrices and arrays. What I'd love - if it exists - is a document showing how to rewrite LaTeX into ConTeXt. Something like the above document, which is now 14 years old. I also notice that much of the contextgarden wiki is outdated. For example, on the use of ConTeXt in MikTeX, we read "As of end of June 2011 MikTeX is still (or again) non-functional." I'm aware that all of this is the work of dedicated and unpaid volunteers, so this is not a complaint! Just an observation. Anyway, as I say, my main issues are converting LaTeX into ConTeXt. and dealing with mathematics. Any pointers would be gratefully received!

Re: [NTG-context] Unexpected symbol with Enumeration
Hi Aditya,Thanks for your hint: I didn't know that subtelty about Lucida OT (and I don't know how to set it up when using Lucida OT).That being said, actually what I would like to use is the kind of script font which is the attached document (those script fonts were widely used in higher mathematics textbooks in France). So when I use mkiv the result is the one I like and is attached to this message (test-scriptfonts-mkiv.pdf). However, thanks to your message I went to check, and noticed that lmtx does not give the same math script fonts, and I don't know what has changed between mkiv and lmtx regarding Asana Math, or the way in which fallback fonts are managed (please see the attached file test-scriptfonts-lmtx.pdf).Thanks for your help: OtaredPS: this the the file test-scriptfonts.tex: Some Font Definitions\definefallbackfamily[myfont][math][Asana Math] [range={uppercasescript,lowercasescript}]% lucida font\definefontfamily[myfont][serif][Lucida Bright OT]\definefontfamily[myfont][math][LucidaBrightMathOT]\definefontfamily[myfont][sans][LucidaSansOT]\definefontfamily[myfont][mono][LucidaSansTypewriterOT]%\setupbodyfont[myfont,10pt]%% End of Font Definitions%%\starttext\startbuffer[test]Testing script fonts in maths\startformulax^2 + y^2 = z^2, \quad \sin(a)^2 + \cos(b)^2 = 1.\stopformula\startformula\cal{A}, \quad \cal{B}, \quad \cal{C}, \quad \cal{D},\quad \cal{E},\quad \cal{F},\quad \cal{G},\quad \cal{H},\quad \cal{K},\quad \cal{L},\quad \cal{M},\quad \cal{P},\quad \cal{S},\quad \cal{T}\stopformula\hairline\stopbuffer\switchtobodyfont[lucidaot]{\bf Lucida OT: }\getbuffer[test]\switchtobodyfont[myfont]{\bf Lucida OT with Asana Math: }\getbuffer[test]\stoptext

[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
$\interior{\overline{A}}$).
Thanks for any help: OK
