[NTG-context] \mathematics might be missing \everymathematics
Dear Hans,
In the following example I want to locally set lcgreek=normal but it is
not picked up because the attribute is not propagated. When I enter
\everymathematics manually it works fine. Is this by design or is this
a bug? MWE below.
Cheers, Henri

[NTG-context] modules or packages for abbreviations for common math commands
Dear ConTeXt folks,
is there a module or a package people have created for common things
used in mathematics.
`\set{ a, b, c }` for a set.
`\EV{X}` for the expected value.
`\P{ X = ½ }` for the probability.
…
If not, maybe a module could be created and maintained together to not
reinvent the wheel.
Thanks,

With regard to mathematics ConTeXt can do all things which plain TeX can.
I mean...can I do...
$\sum_{i=1}^{n}{x_{i}}$
as I used to in LaTeX?
Yes. For displaymath you can use plain TeX's $$\sum$$ or better
\placeformula
\startformula
\stopfromula
(LaTeX's \[ ... \] doesn't work.)
I don't make the \Sigma to be under and over characterised by i=1 and n.
In inline math you need \limits\sum if you want to have the i=1 below
and the n above the sum sign. If I'm not mistaken, LaTeX does the same.

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.

Re: [NTG-context] Change kerning between math characters (prime and left parenthesis)
On 6/2/2017 10:59 AM, Mikael P. Sundqvist wrote:
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:
you can also play withj:
return {
name = "cambria-math",
mathematics = {
kerns = {
[0x1D453] = {
force = true,
topright = {
{
kern = 1000,
},
},
bottomright = {
{
kern = 1000,
},
},
},
},
},
}
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?

Re: [NTG-context] Converting from LaTeX for PDF accessibility tagging?
On Sun, 28 Jun 2020, Alasdair McAndrew wrote: 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. As explained in the last paragraph, there are pre-built shortcuts for the main alignments and you can define your own to match amsmath style, if you wish. If you are worried about typing, look into tab completion for your editor of choice. For example, in vim, I can do `for` which expands to `\startformula ... \stopformula` and `fora` expands to `\startformula \startalign ... \stopalign \stopformula`. 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. AFAIK, pandoc is not aware of context math. When I convert latex to context, I find it simpler to do it some hand written regex which translate commands according to my writing style. 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. The user-interface is still the same. Anyway, as I say, my main issues are converting LaTeX into ConTeXt. and dealing with mathematics. Any pointers would be gratefully received! Can you post an example of LaTeX math that you are having difficulty in converting? It is hard to answer this in the abstract.

[NTG-context] font switches: bold, slanted, etc.
Hi,
Basic font switches are bold (\bf), italic (\it), slanted (\sl), ...
and one can have bolditalic (\bi), boldslated (\bs), etc.
We also have style=bold, style=slanted, etc.
Is there some way to manipulate font switches so that
\bold{This text is \slated{bold}}
for example, would put the word "bold" into boldslanted?
A natural use of this is, e.g. headers that get typeset in bold. What
if the title contains a word, say, in slanted (or, worse, some
mathematics)?

Hi Gour, I added an abstract, an overview section with the plan, and an RSS feed: https://dave.autonoma.ca/blog/2019/05/22/typesetting-markdown-part-1/ One of the reasons I chose Pandoc's Markdown is for its support of classes and annotations. I looked into the pandoc-xhtml link and it looked both incomplete and lacking support for typesetting mathematics. Have a read and let me know what you think!

[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,

I don't think you can, actually. There are no metric files
for oldstyle in the latin modern distribution, only an encoding
vector (and .map).
Pdftex either uses entries from the 'lining' map file, or from
the 'oldstyle' mapfile, but it has no way of distinguising
between the two (the fonts have the same metrics).
The reverse of the old oldstyle trick should work though:

[NTG-context] Footnote in columns interlinespace
Good noon.
I typeset a document in two columns on the grid. Footnotes I place in
the "columns".
\setupfootnotes
[rule=off, way=bypage, location=columns, conversion=set 3,
before={\blank[line]}]
\setupfootnotedefinition
[location=left,width=fit, sample={\mathematics{\star\star\star}\
},hang=1]
How can I set interlinespace to a smaller distance? (I don't care that
the footnote lines would not be on the grid---I prefer it to a very
loose interlinespace.) I guess that there is better way than to write
\footnote{\setupinterlinespace[line=9pt] ...\par}
Moreover, it doesn't work well since on the first line is apparently
inserted a strut.
Many thank for you help.

[NTG-context] strange text/math spacing
Hi,
I found a small but annoying thing about math. When I typeset in-line formula
like '...a vector of $a_x$ is...', it creates too little space between 'of' and
succeeding lowercase math symbol.Uppercase math symbol is treated right. I can
leave it as it is, but it strange to me why TeX performs poor on that.
(There too many 'of' for testing purposes).
\starttext
In MATLAB, we can create the Leslie matrix using {\tt gallery('leslie', A, B)}

This is probably not satisfying, because you probably want to get new
mathematics commands working, but if this is to be used solely in text,
you could use (or expand to):
b\low{off}
\low (and \hi and \lohi) look like they work robustly in both math and
text modes.
I'm a bit confused by you using \newcommand in your (ConTeXt?) examples,
though...

Re: [NTG-context] Proposal for math mappings
Dear Aditya,
I do think that your proposal would be of great help in writing mathematics.
Indeed the use of different alphabets, or range of characters with different
styles, depend on the fields of mathematics, so having a \setup command like
the one you suggest would be wonderful.
However, IMHO, the new setup command should follow the general rules of ConTeXt
commands for setting up different environments. So maybe the option of having
all the 12 forms, as you suggest,
normal, italic, sans, sansitalic, blackboard, script,
bold, bolditlaic, boldsans, boldsansitalic, boldblackboard, boldscript
would be more homogeneous with the usual style choice.
Best regards: OK

[NTG-context] \hpos in math
Hello List,
I am working on a project which combines graphics with formulas, like this:
hposQuestion.pdf
Description: Adobe PDF document
My code for creating this formula is attached. It works well, but I have a
couple of questions that could make it work better.
1) Is there a mathematics version of \hpos? The contents of \hpos are set as
text, even when \hpos is in mathematics, so I wrote an \mpos macro that uses
\hpos but sets the contents as display-style math. This isn’t great for
spacing, and it does't adapt to different math styles. \framed has a math
version, \mframed, that sets the contents in the appropriate math style. If
anyone know a way to accomplish that with \hpos, I’d love to know.
2) Is there a way to limit the scope of the \hpos labels to a single formula.
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?
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.
Thanks!
Gavin
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]

Yeah, appears to be the correct range. Couldn’t test with Lucida,
though.

But if there’s a math font, I’d go with the example that Wolfgang
posted; alternatively just wrap the converter into \mathematics:
\unprotect
\def\math_greek_characters#1{\mathematics{\greeknumerals{#1}}}
\defineconversion [mathgreek] [\math_greek_characters]
\protect
etc. It will depend on your choice of math font whether you get
italics or upright glyphs.

Re: [NTG-context] At a loss how to proceed
Hans et al, OK, some questions. You say "starting with pure tex," does this mean that if you start with Context, then tex4ht is not an option? Secondly, since I teach mathematics, anything I write is going to contain a *lot* of mathematics and a lot of figures (graphs, etc). Is XML and MATHML going to be painful in this case? How can I get started with a small project or example, so I can determine how to proceed? I think I can look at the latex followed by tex4ht direction myself, but I could use some help with the second method, xml to pdf via context and xml to html via xst. I really have no idea how to proceed with this direction.

Hallo,
thanks to Adam, it was easy to implement font variants. A little bit
more work was with all Storm glyph deffinition in two (+one) encodings.
Before I will do the support for the rest of my Storm font families I
want to ask audience (and especially Hans, Adam) to have a look into the
files (http://typokvitek.com/tmp/context-storm.zip). Example in
http://typokvitek.com/tmp/test-sdynamo.pdf (generaly interesting for all
\show... font related command usage). Recommendation for the package
improvements are welcomed.
There are:
enco-st1.tex - ec encoding with storm glyph extension
enco-st2.tex - xl2 encoding with storm glyph extension
enco-st3.tex - variants (additional glyph) for enco-st1 and enco-st2
type-sdynamo.tex - typescripts for Storm Dynamo font family
math-sto.tex - simple mathematics present in Storm fonts (in progress)
test-sdynamo.tex - test file
test-storm.tex - support for tests
Questions:
? During encoding deffinition I found some chracter name mess. I solved
it by synonyms:
E.g. \definecharacter textdag{\dagger}
\definecharacter paragraphmark {\paragraph}
\definecharacter textellipsis {\ellipsis}
\definecharacter textminus {\minus}
\definecharacter ostroke{\oslash}
\definecharacter textdollar {\dollar}
Is there some context convention for character names?
? I have a problem to define mathematics chars. I did:
\starttypescript [math] [dynamoRE] [st1]
\definefontsynonym [DynamoRE-Math-Letters][sdgr8te]
[encoding=st1]
\definefontsynonym [DynamoRE-Math-Letters-Italic] [sdgri8te]
[encoding=st1]
\definefontsynonym [DynamoRE-Math-Symbols][sdgr8te]

\stoptypescript
\starttypescript [math] [dynamoRE] [name]
\definefontsynonym [MathRoman] [DynamoRE-Math-Letters]
\definefontsynonym [MathItalic][DynamoRE-Math-Letters-Italic]
\definefontsynonym [MathSymbol][DynamoRE-Math-Symbols]
\definefontsynonym [MathExtension] [ComputerModernMath-Extension]
\stoptypescript
\starttypescript [DynamoRE] [st1,st2]
\definetypeface [DynamoRE] [ss] [sans] [dynamoRE] [default]

\startmathcollection[storm]
\definemathcharacter [+] [bin] [sy] ["2B]
\definemathcharacter [=] [rel] [sy] ["3B]

Where is the problem?
? - \starttypescript [*] [fallback] is generaly useful. Is a good idea

[NTG-context] 2 issues in phys-dim.mkiv
I've tried the unit interface today, and I've noticed two issues with the
following example:
\setupunits[alternative=text]
\starttext
$\unit{-4.6e-3 km s^-1}$
\stoptext
1. Minus superscripts for UNITS (so 's^-1' here—not 'e-3', which is fine)
are converted to hyphens with the 'text' unit alternative (with the default
'mathematics' unit alternative everything is fine):
2. The times symbol between the number and the 10^-3 (e-3) is incorrectly
spaced (as an ordinary math atom instead of a binary math atom) so doesn't
look good.
Maybe Hans could change
\def\digitstimessymbol{\times}
to
\def\digitstimessymbol{\ifmmode\times\else${}\times{}$\fi}
in phys-dim.mkiv?

FWIW, you can have Emacs automatically display ∫ in place of \int etc. in your file (and this is no real substitution, just for viewing). Also, Emacs has the "TeX input method", where typing the four keys \, i, n, t yields ∫ (a Unicode symbol) etc. (It works also for inputting properUnicode accented letters, which is very cool and useful.)

[NTG-context] Labelling with textext

for a - sign (but not actually typeset the -) after the number in the
case where the number itself is negative. I am trying this
label.bot(textext("$" & decimal(x) & "\hphantom{-}$"),(x*u,ay*u));
which fails. If I remove the \hphantom command, i.e.,
label.bot(textext("$" & decimal(x) & "$"),(x*u,ay*u));
the command is successful, but the number being labeled is not exactly
horizontally centered below the point in question since the - symbol
preceding the number pushes it a little to the right. Thoughts on how
to achieve my desired \hphantom effect?

[NTG-context] Numerals in mkiv
Hi Hans,
It seems that Arabic or Persian numerals (for instance in section

languages :-)

[NTG-context] A question on drawing functions in MetaFun
I tried to generate "Figure 9.2 An example of a graphic with labels along the axes." in metafun-p.pdf (p.209), but could get only graphics without labels. I used the codes in the page 208 as follows (see the attached file) \startMPpage StartPage ; ... codes in p.208 here ... StopPage ; \stopMPpage In this case, the generated MPS file (ch93-1-mpgraph.1) had the bounding box (0, 0, 420, 596). When I used \startuseMPgraphic instead of \startMPpage, the generated MPS file had the different bounding box (-47, -17, 300, 575), and I could see the right one. Please tell me what I missed.

Hans et al, OK. I'd like to start with mfonts.tex. I am working with GWTeX on Tiger and have just updated to all of Gerben's latest stuff, so I am as current as I can be with that distribution. I do have Ruby on this Mac. So, hold my hand and and guide me through the compile stage. The first problem, as I see it, is to get the expected organizational tree for these manuals For example, in mfonts.tex, we have: \environment ../allkind/mcommon.tex So, should I do some sort of cvs thing and check out all these manuals and documents?

The mathematical center of the line is not necesarily the
optical center, so a somewhat more correct approach would
put all the stuff in an \hbox and then compute manually
how far it has to drop down.
For a more pleasing look, it would perhaps be even better
to line up a normal '7' as if it was an oldstyle numeral,
and then enlarging it while keeping the same vertical
alignment ratio.

Ok. The third argument of \genfrac should be {} and not \empty,
otherwise \ifx @#3@ in \genfrac evaluates to false. So, either we need
to change \ifx @#3@ to something more robust, or revert back to older
definitions of (d|t)frac.

I was going to ask exactly the same question. Unluckily, what you
did here does not work very well for me - the line is quite below
the header text, I would really like to have it closer...
\setupheader[after={\hairline}] does not work as the hairline
is not below the text but starts at the left border...
Maybe someone got another idea?

[NTG-context] At a loss how to proceed
All, Lately, I've had a number of discussions with the director of disabled student services at our school regarding document preparation for the visually impaired. As a result of these discussions, I am a bit lost as how to proceed with the preparation of mathematics for the web and documents for my course content. I've paid a little attention to the develoment of MathML, but I've always said "Who wants to code like that?" whenever I look at examples. However, today I found: http://www.dessci.com/en/company/press/releases/040722.htm I now realize that software that reads web pages aloud it pretty important. But how do I, in my limited time, prepare documents for multiple purposes? Can I use Context to support all of our students at our school? Just how do I proceed? At a loss. ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context
[NTG-context] Issue in btx rendering
Hi,
[my current version: 2022.05.02 16:19]
With the past two-or-so uploads, btx output seems to be broken in some cases.
Compiling the below example
\usebtxdataset[refs.bib]
\usebtxdefinitions[aps]
\starttext
This reference has a tag which is in camel-case:
\cite[Nielsen2011_ChernoffInformationExponentialFamilies]
On the other hand this reference has a tag which is lower-case:
\cite[vaart1998_asymptoticstatistics]
\placelistofpublications
\stoptext
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] Figure number off one time
Very nice. This worked well. Thanks Hans.
In connection with this same question, consider the small example
that follows. My thinking was that I would like to have a couple of
lines of the paragraph in the output, then let the rest of the
paragraph wrap around the figure positioned at the right of the page.
However, I get a paragraph break and an indent.
Workaround?

\section[sec:pythagoras]{The Pythagoreean Theorem}
Pythagoras was a Greek mathematician and philosopher, born on the
island of
Samos somewhere near the year 582 BC. He founded a number of schools,
one in
\placefigure
[right,nonumber][fig:pythagoras]
{Pythagoras.}
{\externalfigure[Pythagoras][width=4cm]}
particular in a town in southern Italy called Crotone, whose members
eventually became known as the Pythagoreans. The inner circle at the
school, the {\em Mathematikoi}, lived at the school, rid themselves
of all personal possessions, were vegetarians, and observed a strict
vow of silence. They studied mathematics, philosophy, and music, and
held the belief that numbers constitute the true nature of things,
giving numbers a mystical or even spiritual quality.
Today, nothing is known of Pythagoras's writings, perhaps due to the
secrecy and silence of the Pythagorean society. However, one of the
most famous theorems in all of mathematics does bear his name, the
{\em Pythagorean Theorem.}

[NTG-context] function machine
Hans, Taco, et al,
This is getting pretty close to the limit of my expertise. The good
stuff of it is stolen from Metafun and mp-func.mp.
Because of the way I handle clipping the path,
p:=p cutbefore cpath;
p:=reverse p;
p:=p cutbefore cpath;
this will only work on functions (like lines, quadratics, and
polynomials, maybe sinusoids) that both enter and leave the region
inside the clipping path.
I proceed the in the order I do because I want the axes layered atop
the grid and the functions layered atop the grid and axes.
It's actually a pretty cool routine for teachers as it almost works
like a TI83 calculator. Just change xmin, xmax, xscl, ymin, ymax, and
yscl to determine domain and range and tick marks, then adjust the
number of points for a smooth graph, then set the width of the figure
you want. There's an option to label the axes differently from the
usual x and y, if needed.
Finally, thanks to Hans' expertise, the drawfcn routine allows for a
parametric definition of the intended curve.
All you need to do to make another graphic is copy and paste
everything between \startMPpage ... \stopMPpage and adjust the
parameters described above. Now you have a second plot.
You can run texexec with
texexec filename
or
texexec --page=2 filename
if you only want your second graphic. When I compile all, I write an
xml database file (very cool) and use
\usemodule[fig-base]
\usefigurebase[figures/figlibSection1]
in my document. Very cool working arrangement.
Here's some lines from my xml file:

And here's my function machine. I'd love to hear any suggestions for
improvement. Thanks to all who have helped me the last week (Taco has
been especially patient). I've learned a lot.

Re: [NTG-context] Linespacing modified across document
On 1/23/2022 8:58 AM, Alexandre Christe via ntg-context wrote: Dear list, I've noticed that in my document the linespacing (verified with \the\baselineskip) is not consistent across the whole document. In the first section, it's fine (no maths). Later on, it gets increased by some amount, which tends to depend on what kind of mathematics are in between, so it's not constant. Has anyone else noticed this too? It can depend on the ht/dp ratio of the font, so maybe you need to adapt that (when setting up linespacing).
