[NTG-context] Reconciling unicode-math with LaTeX2e mathematics

To be more precise (please see the enclosed P.D.F. file), I would like the
same font possibilities in ConTeXt math mode as shown in the following
table from Will Robertson's talk at 41 min 40 s for LaTeX unicode-math
package:
https://youtu.be/FW9Cwh9sj5w?t=2500
In both LaTeX and ConTeXt, we have two kinds of fonts:
— a text font: multi-letter words;
— a math font: single letter words.
In math mode, using LaTeX, text fonts can use both
— text spacing: $\textit{abc ffi}$ gives abc ffi;
— math spacing: $\mathit{abc ffi}$ gives abcffi.
In math mode, using LaTeX, math fonts can use only math spacing: $abc ffi$
gives abcffi.
($abc ffi$ is equivalent to $\symit{abc ffi}$—\symxx commands were
introduced in the 2015 update of the unicode-math package by Will
Robertson, allowing upright, slanted, bold, etc. math fonts with \symup,
\symsl \symbf, etc., respectively.)
However, in math mode, using ConTeXt, text fonts can use only TEXT spacing
(no MATH spacing commands): $\text{\it abc ffi}$ gives abc ffi. So this is
the FEATURE that needs to be added. I suggest that you implement a new set
of commands called \textxx for this (text fonts with MATH spacing in math
mode—please see the enclosed P.D.F. file).
As far as math fonts are concerned using ConTeXt in math mode, it's okay:
$\it{abc ffi}$ gives abcffi. But you should note that in the source of
ConTeXt you (Hans) introduced \mathit (and \mathup & \mathtf, \mathsl,
\mathbf, etc.) as an equivalent of \it (\tf, \sl, \bf, etc., respectively)
for "A.M.S. LaTeX compatibility", though in A.M.S. LaTeX the \mathxx
commands are not MATH fonts but TEXT fonts with math spacing (as pointed
out by Will Robertson in the very first seconds from 41 min 40 s of his
talk in the link above) so it not compatible (but that's fine since the
name \mathxx in A.M.S. LaTeX was not very well chosen in the first place
but thereafter kept for backward compatibility, so that in ConTeXt we can
keep it used for MATH fonts instead and introduce \textxx for TEXT fonts
with math spacing, as suggested in the previous paragraph).
Please see the enclosed P.D.F. file that sums everything up to understand
visually what I mean with the missing feature I request (adding new \textxx
commands for text fonts with MATH spacing in math mode), and let me know
what you think.

[NTG-context] Reconciling unicode-math with LaTeX2e mathematics
Is there a plan to have in ConTeXt the same kind of math behavior that Will Robertson implemented in the last version of his unicode-math LaTeX package (\mathrm, \mathit, \mathbf, \symrm, \symit, \symbf, etc.)? Because ConTeXt currently has the same math/text spacing issues in math mode that the old unicode-math package had.

[NTG-context] Changing font for math function
Aditya Mahajan:
By default, in all three formats the font for \log is mathupright rather
than textrm. There needs to be a rationale for ConTeXt default to be
different from other formats. Do you have any reference to a math book or
journal that uses text fonts for \log-like operators?
Thanks for the examples. I had forgotten that math fonts can differ from
text fonts. Now I understand why you use \mathupright (which, according to
the source code is identical in math mode to \mathrm and \rm). And I know
that math fonts have different kerning and ligatures than text fonts.
But how is that in LaTeX, kerning and ligatures in math mode inside \mathrm
are the same as those of the TEXT font (while in ConTeXt \mathrm still uses
the kerning and ligatures of the math font, which seems logical)? Compare
the following:
LaTeX:
\documentclass{article}
\begin{document}
affinity\par
$\mathrm{affinity}$\par % kerning and ligatures of TEXT mode with math font
\end{document}
ConTeXt:
\starttext
affinity\par
$\mathrm affinity$\par % kerning and ligatures of MATH mode with math font
\stoptext

[NTG-context] Changing font for math function
Aditya Mahajan:
The default should be \mathupright (as is the case in amstex
and latex, and probably also plaintex).
Hans Hagen:
next beta: when one of the stylealternatives text mode else mathmode
(default nothing == math upright)
Hans Hagen:
Because like in \mtext, the \text command is ESSENTIAL (for the function
names to have the mathcodes, kerning and ligatures of the text mode instead
of the ones of the math mode).
that is not needed because if you use a style known as text style a text
font is used
Alright, but why not ALWAYS use your text style (or my \text), why talking
about \mathupright then? \mathupright should never be used to display a
name in text style in my opinion. I don't get it, is there something that I
missed with that \mathupright? (And I'm not managing to download the new
beta of yesterday so I don't have access to the new code yet).
Appart from that story of \text or not \text, what do you think about the
suggestion that I gave in the conclusion of my previous post? Do you plan
to still use version 1 or to implement version 2 after the freeze for
TeXLive 2015? My conclusion was:
CONCLUSION. — It all comes down to the choice of the best user interface
for math functions and math texts (usually used as subscripts of
variables). Their styles and colors is handled with \setupmathematics.
There are two choices of user interface:
1. $\normalmathop{\mfunction{Arsinh}}\nolimits x\ \text{and}\
n_{\mtext{air}}$.
2. $\mfunction{Arsinh} x\ \text{and}\ n_{\mtext{air}}$.
First, the default functionstyle and textstyle in \setupmathematics should
be \rm\tf (the text mode equivalent of \mathupright, as we are always in
text mode thanks to the \text hardcoded in \mfunction and \mtext).
Then, in the 1st solution \normalmathop is used instead of \mathop because
the latter is modified by ConTeXt to convert \rm to \mf, which makes
\setupmathematics[functionstyle=\rm] without effect.
The 2nd solution is obviously way cleaner, that is why I think it should be
preferred. The implementation is given in my '2nd DEFINITION of \mfunction'
for replacing the existing definition in math-ini.mkiv:
———
\unexpanded\def\mfunction{\dosingleempty\domfunction}
\def\domfunction[#1]#2%
{\iffirstargument
\doifelse{#1}{op}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}}{\doifelse{#1}{limop}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}}{\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}\nolimits}}
\else
\normalmathop{\text{\usemathematicsstyleandcolor\c!functionstyle\c!functioncolor#2}}\nolimits
\fi}
———
We also saw that \mfunctionlabeltext is inconsistent with ConTeXt
\labeltext because the former has a style attached to it, so
\mfunctionlabeltext should be removed from math-ini.mkiv and
\mfunction{\mathlabeltext } should be used instead when needed.
To go even further in userfriendlyness, we the new macro \definemathcommand
should be added in math-ini.mkiv:
———
\unexpanded\def\definemathfunction{\dodoubleempty\dodefinemathfunction}
\def\dodefinemathfunction[#1][#2]#3%
{\ifsecondargument
\definemathcommand[#1]{\mfunction[#2]{#3}}
\else
\definemathcommand[#1]{\mfunction{#3}}
\fi}
———
Finally, with this new \mfunction definition and the removal of the
misleading \mfunctionlabeltext, the functions defined in math-def.mkiv
should be rewrite as:
———
\definemathcommand[cos]{\mfunction{\mathlabeltext{cos}}} % Or
\definemathcommand[cos]{\mfunction[nolop]{\mathlabeltext{cos}}}, it is the
same.
\definemathcommand[det]{\mfunction[limop]{\mathlabeltext{det}}}
\definemathcommand[diff]{\normalmathop{\text{\mathfunctionstyle
d}}\mathopen{}}
%etc.
———
or
———
\definemathfunction[cos]{\mathlabeltext{cos}} % Or
\definemathfunction[cos][nolop]{\mathlabeltext{cos}}, it is the same.
\definemathfunction[det][limop]{\mathlabeltext{det}}
\definemathcommand[diff]{\normalmathop{\text{\mathfunctionstyle
d}}\mathopen{}} % It is a special function so it should still be treated
with the more general \definemathcommand.
%etc.
———
ConTeXt users are now provided, if Hans agrees to implement the code given
in this conclusion, with three extremely useful macros:
— \mtext (that should be used for all math texts such as subscripts of
variables):
$n_{\mtext{air}}$;
— \mfunction (the equivalent of LaTeX \operatorname macro of the amsopn
package):
$\mfunction{Arsinh} x$
$\mfunction[op]{Arsinh} x$ or equivalently $\mfunction[limop]{Arsinh} x$;
— \definemathfunction (the equivalent of LaTeX \DeclareMathOperator macro
of the amsopn package):
\definemathfunction[arsinh]{Arsinh} $\arsinh x$
\definemathfunction[arsinh][op]{Arsinh} $\arsinh x$ or equivalently
\definemathfunction[arsinh][limop]{Arsinh} $\arsinh x$.

[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?

\mfunction + \kern\zeropoint + \newmathcodes is the way to go). For

\ifnum a ConTeXt macro?

[NTG-context] ConTeXt equivalent of \newmcodes@
do you have an example of usage
Yes, I am trying to create the command \operatorname in ConTeXt. I know
that in LaTeX \operatorname{xyz} is equivalent to
\mathop{\newmcodes@\kern\z@\operator@font xyz}\csname nolimits@\endcsname}
according to the AMSopn package (
http://www.bakoma-tex.com/doc/latex/amsmath/amsopn.pdf), and I am trying to
translates that in ConTeXt:
\mathop{\newmcodes@\kern\zeropoint\mfunction{xyz}}\nolimits
but \newmcodes@ produces an error.
In LaTeX, \newmcodes@ is defined as
\begingroup \catcode`\=12
\gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\.613A%
\ifnum\mathcode`\-=45 \else
\mathchardef\std@minus\mathcode`\-\relax
\fi
\mathcode`\-45\mathcode`\/47\mathcode`\:603A\relax}
\endgroup
according to the AMSopn package, so I have copied the code in my document
(I only removed the @ so that I don't have to convert its catcode) but the
if condition gives an error (however it compiles fine without the if
condition).
I also know that there is the ConTeXt command
\definemathcommand[nolop]{xyz} which I thought stands as an equivalent to
the \operatorname wrapper \DeclareMathOperator, but apparently not since it
doe not use the 3 commands
1. \newmcodes@
2. \kern\z@
3. \operator@font
in it, so I wonder the point of such a wrapper since all it seems it does
is translates to
\mathop{xyz}\nolimits
To sum up, I would like to have a \DeclareMathOperator in ConTeXt, so here
are my 2 questions:
1. What is the ConTeXt equivalent of \newmcodes@?
2. What is the point of \definemathcommand?

[NTG-context] ConTeXt equivalent of \newmcodes@
Does \definemathcommand [xyz] [nolop] {xyz} do what you want?
Not really if, instead of xyz, I want a name with hyphens, quotes, stars or
colons. Compare the output of
\definemathcommand[xyz][nolop]{fancy-function-name'*.:}
in ConTeXt with the output of
\DeclareMathOperator{\xyz}{fancy-function-name'*.:}
in LaTeX. What I can do is
\definemathcommand[xyz][nolop]{\kern\zeropoint\mfunction{fancy-function-name'*.:}}
which gives the same result as \DeclareMathOperator, except for the hyphens
and the star are converted into binary operators and the colon which is
preceded by a space, since I didn't use \newmcodes@, that is why I asked
how to implement the macro \newmcodes@ in ConTeXt, which is defined in
LaTeX as
\begingroup \catcode`\=12
\gdef\newmcodes@{\mathcode`\'39\mathcode`\*42\mathcode`\.613A%
\ifnum\mathcode`\-=45 \else
\mathchardef\std at minus\mathcode`\-\relax
\fi
\mathcode`\-45\mathcode`\/47\mathcode`\:603A\relax}
\endgroup
so that the following code can compile in ConTeXt:
\definemathcommand[xyz][nolop]{\newmcodes@
\kern\zeropoint\mfunction{fancy-function-name'*.:}}

why use math here?
It was to avoid oldstyle figures that I use by default. But finally it's
better to use oldstyle figures even in tables.
Another question about fonts. Is there a way to define a conditional
mathcommand based on the current alternative style? For instance, in the
following example I would like to keep the bold effect but with adaptation
to the local alternative style (in text mode, when the local alternative
style is \tf I would like the mathcommand to be \bf, when it is \it I would
like \bi, when it is \bf I would like \bf and when it is \bi I would like
still \bi):

[NTG-context] Two coexisting number conversions (in headers and in texts)
Hello,
How can I achieve this chapter numbering?
— page 1:
I My chapter (header)
-
First My chapter (text)
— page 2:
II My chapter (header)
--
II My chapter (text)
That is to say having every chapter number in roman numeral except the
first one but only in the text (not in the header).
For the moment I can achieve only the chapter numbering for the text but
not for the header:
\define[1]{\myconversion}{\ifcase #1\relax \or First\else
\convertnumber{Romannumerals}{#1}\fi}
\defineconversion[myconversion][\myconversion]
\setuphead[chapter][conversion=myconversion]
\setupheadertexts[{\getmarking[chapternumber]\quad\getmarking[chapter]}]
\starttext
\startchapter[title=My chapter]
\stopchapter
\startchapter[title=My chapter]
\stopchapter
\stoptext
Best regards.

[NTG-context] Head titles and section blocks bug in s-pre-60.tex module
Hans, I think there is a bug in your s-pre-60.tex module regarding the step mechanism interacting with section blocks: the head titles disappear each time ConTeXt starts a new section block. I have found a way to solve this problem by putting \StartSteps\StopSteps (empty pair, and it works also with \StartStep\StopStep empty pair) right after the start of each section block, like this for instance: \startbodymatter\StartSteps\Stopsteps blablabla \stopbodymatter. Could you correct this? Here is a minimal example illustrating the problem: \usemodule[pre-60] \setupinteraction[state=start] \starttext \startfrontmatter \startsection[title=My frontmatter section] % -- Title displayed: fine. \StartSteps \startitemize \item my item\FlushStep \item my item\FlushStep \item my item\FlushStep \stopitemize \StopSteps \stopsection \stopfrontmatter \startbodymatter \startsection[title=My bodymatter section] % -- Title NOT displayed: bug? \StartSteps \startitemize \item my item\FlushStep \item my item\FlushStep \item my item\FlushStep \stopitemize \StopSteps \stopsection \stopbodymatter \startbackmatter \startsection[title=My backmatter section] % -- Title NOT displayed: bug? \StartSteps \startitemize \item my item\FlushStep \item my item\FlushStep \item my item\FlushStep \stopitemize \StopSteps \stopsection \stopbackmatter \startappendices \startsection[title=My backmatter section] % -- Title NOT displayed: bug? \StartSteps \startitemize \item my item\FlushStep \item my item\FlushStep \item my item\FlushStep \stopitemize \StopSteps \stopsection \stopappendices \stoptext Regards. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
[NTG-context] Empty heads after leading whitespace
For those who are interested, I've finally solved my problem (the vertical
space before a subsection which was not automatically swallowed at the top
of a page when the page started with an empty section) by using the pair
'after={\vskip 0em\blank[disable]}' for sections:
\setuphead
[section]
[placehead=empty,
page=yes,
after={\vskip 0em\blank[disable]}]

[NTG-context] Empty heads after leading whitespace
Thanks Wolfgang. I could even have sections in the TOC with
'\setuptexttexts[{\placerawheaddata[section]}]'.
However, how can I start a new page at each new section? The 'page=yes'
pair does no longer work with your solution 'placehead=hidden' (since the
head is not placed I guess). I also tried 'before=\page' or 'after=\page'
without more success. Here is a minimal example showing the absence of page
breaks though I specified 'page=yes' (the section numbers are also
mismatched but if one puts manual page breaks they match again, so it's not
really a problem for me):
\setupheadertexts[\namedstructurevariable{section}{title}][]
\setuphead
[section]
[placehead=hidden,
page=yes] % -- This key does NOT work.
\setuphead
[subsection]
[placehead=yes,
before={\blank[line]},
after={\blank[line]}]
