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
I have no clue how latex implements it (and don't care much either) but
in context we use a unicode approach and \mathrm switches to another
math alphabet ... in fact, affinity is just a sequence of a f f i n i t
y (symbols, variables, whatever) and not a real word. You can use
\text{affinity} but of course all depends on what the font setup is (and
if your bodyfont has the same shapes for math and text).
Bottom line: if you switch to \mathrm etc you don't switch fonts of
styles, you switch to another alphabet. One can of course map these
internally onto some text font but context doesn't work that way.

Fantastic! Thank you Hans, it is way better than the old mechanism
\setmathfunctionstyle. Now I have a few suggestions to improve the
consistency of this new mechanism. First, I think this functionstyle key
a) should be better called 'mathlabelstyle';
No. The style applies to anything called using \mfunction{...}, so
functionstyle and functioncoloar are appropriate keys.
b) be default to \tf to make the FONT ALTERNATIVE always upright;
I disagree. The default should be \mathupright (as is the case in amstex
and latex, and probably also plaintex). We now have the option to change
it to \tf if desired.
c) be linked to this following new definition in math-ini.mkiv:
+ \unexpanded\def\mathlabel#1{\text{\mathlabelstyle #1}}
so that \mathlabel can be used for labeling math objects like functions but
ALSO for labeling variables with subscripts (e.g., \rho_{\mathlabel{air}}).
The hardcoded \text in the definition of \mathlabel is used here for these
5 reasons:
Hans already replied to that.
That \mathlabel should replace \mfunction which should be removed, and
\mfunctionlabeltext should be removed as well and one should directly use
the already defined \mathlabeltext instead, for these 3 reasons:
I strongly disagree to this. These are two completely different issues
(wanting a macro to tag multiletter variable names vs a macro to tag
log-like operators).
1. Every command containing the word 'labeltext' should not have a style
attached to it.
2. The word 'function' is misleading because \mfunction and
\mfunctionlabeltext do not create a \mathop atom and it makes the user
believe its usage is restricted for labeling functions while the command
should also be used for labeling variable with subscripts (e.g.,
\rho_{\mathlabel{air}} is far better than \rho_\mfunction{air}).
3. Using only \mathlabeltext with \setuplabeltext is also more consistent
with the current \labeltext that works with \setuplabeltext.
Thus the function definitions in math-def.mkiv should be changed:
- \definemathcommand [arccos] [nolop] {\mfunctionlabeltext{arccos}}
+ \definemathcommand [arccos] [nolop] {\mathlabel{\mathlabeltext{arccos}}}
etc.
I don't see the rationale for this.
And I think you should add in this file the definition of the differential
operator which is so widely used in mathematics, so that users have at
their disposal once for all a proper implementation of this operator and
don't have to make their own hack:
+ \definemathcommand[diff]{\mathop{\mathlabel{d}}\mathopen{}}
Note that there is no consensus on how the `d` in calculus should be
typeset. There are also \differentiald and \differentialD that map to
unicode slots.
\definemathcommand[arsinh][nolop]{\mathlabel{arsinh}}
\starttext
$\arsinh z = \ln\bigl(z + \sqrt{z^2 + 1}\bigr)$\par
$\rho_{\mathlabel{air}} = \frac{p}{R_{\mathlabel{specific}}T}$\par
\stoptext
\mfunction already does that.
I'll reply to the rest of the message later.

operators—useful if one wants to call its function or subscript
'low-frequency' for instance—, apostrophes are not converted to
primes—useful if one wants to call its function 'Riemann's function' for
instance).
3. It uses proper kerning (if one wants to call its function or
subscript 'WALL' for instance).
4. It uses proper ligatures (if one wants to call its function or
subscript 'efficiency' for instance).
5. It avoids the user having to add \kern\zeropoint to prevent vertical
alignment to the middle of the fraction bar when used inside \mathop for
one-character function names (if one wants to call its function 'd' for

mfunction will stay as it is also needed for tagged pdf and exporting
(basically it's an apply math function thing) so if something else is
needed another name/mechanism have to be made (with appropriate tagging)
the label itself is a special case as it's optional (and is just there
for cultural differences as not all countries use the english names)
so, \rho_{\mathlabel{air}} is something different then, some kind of
multi-character variable?

Hi Aditya,
Thanks for your remark: indeed with the correct use of \underline, I get what
was intended, but somehow before yesterday ConTeXt was more tolerant and for
years it accepted my wrong definition of \liminf…
However, with the new features of \setupmathematics, the underlined word lim
has two colors: for instance with the option
\setupmathematics [functioncolor=red]
the word lim is in red, but the underline is in black.
If I understand correctly, the option
\setupmathematics [functionstyle=\normalrm, functioncolor=red]
uses the normal roman font in math mode, that is math italic if for instance
one is using LM roman as text font. Am I right?
A final question: assuming one needs somewhere a command named weak limit, that
is \weaklim, I tried the following definition:
\definemathcommand [weaklim] [limop] {\mfunctionlabeltext{weaklim}}
but I don’t get the word weaklim printed: what am I doing wrong?
Here is the example:
% begin weaklim.tex
\definemathcommand [weaklim] [limop] {\mfunctionlabeltext{weaklim}}
\starttext

Re: [NTG-context] Changing font for math function
Hi Hans,
Thanks for the new feature in \setupmathematics.
I did some testing of the feature on a several documents, , and followed the
discussions you had with Aditya and Wolfgang.
Everything works fine, except that when one tries to modify, for instance the
definition of \liminf (in order to have it as an underlined lim), ConTeXt
reports an error.
Please see below the minimal example and the error message.
In the minimal example if you uncomment the lines modifying the definition of
\liminf on gets an error message.
begin test-functionstyle.tex
\setupmathematics
[functionstyle=\ss,
functioncolor=red]
%\unprotect
%\definemathcommand [liminf] [limop] {\underline\mfunctionlabeltext{lim}}
%\protect
\starttext
\startformula
f = \sin i\omega x^{\sin(x^{\sin(y)})}
\stopformula
Fatou's lemma implies
\startformula
\int_{\Omega}\liminf_{n\to\infty} (1+\cos(n|x|))dx \leq
\liminf_{n\to\infty}\int_{\Omega}(1+\cos(n|x|))dx.
\stopformula
\stoptext
end test-functionstyle.tex
The error message is:

I realize that this takes us back to the old 'bold-math-in-section-heads'
debate. With the current implementation:
\setuphead[section][style=bold]
\section{$\sin x$}
sin is bold, and if you implement the change that I am suggesting, then
\sin
will not be bold in section titles. If someone prefers \sin to be bolded in
section headers, he would have to add
\setupmathematics[functionstyle=\bf] in
the section style as well.
the next stage of the math font project will provide some real bold fonts (so
bold alphabets get heavy variants)

this is evil (as it's unpredictable, so no support for side effects):
% \prependtoks \rm \to \everymathematics
Is there no better way to use upright letters in math except the line above?
for functions one can now use:
\setupmathematics
[functionstyle=\rm]
and for other changes the normal alphabet changing commands. For text one has
the text commands. Keep in mind that in the regular math stream we don't
think of fonts but of alphabets
The bold and italic symbols/letters aren’t a problem because the have their own
unicode points but for the normal upright characters there should be proper key
(like the lcgreek and ucgreek keys) which prevent ConTeXt to make them into
italic characters. The \everymathematics hack works but isn’t very nice.
\setupmathematics[lcgreek=normal]
\setupbodyfont[cambria]
%\appendtoks \rm \to \everymathematics
\starttext
\m{α훂훼휶}
\m{D퐃퐷푫}
\m{{\rm D}퐃퐷푫}
\stoptext

best test this because Mojca will at some point push into tex live (at
which moment we have a current)
Thanks. This works correctly on a small test. I will test this more
thoroughly.

\sin etc should not behave like \text{...}. \text should adapt to the
surrounding style while \mathoptext should not. In particular, in the
following
{\ss $\sin x$}
{\bf $\sin x$}
\sin should be in normal text upright font and not adapted to the surrounded
text.
Is it possible to set a value of functionstyle so that the surrounding text font
styles are ignored (but the font size is not).
I realize that this takes us back to the old 'bold-math-in-section-heads'
debate. With the current implementation:
\setuphead[section][style=bold]
\section{$\sin x$}
sin is bold, and if you implement the change that I am suggesting, then \sin
will not be bold in section titles. If someone prefers \sin to be bolded in
section headers, he would have to add \setupmathematics[functionstyle=\bf] in
the section style as well.
