[NTG-context] ConTeXt equivalent of \newmcodes@
\definemathcommand[xyz][nolop]{\text{fancy-function-name'*.:}}
The problem with this solution is that the font of the operator becomes the
normal text font whereas I want to use the standard math upright font (so
\mfunction + \kern\zeropoint + \newmathcodes is the way to go). For
instance with \setupbodyfont[sansserif] the operator name becomes sans
serif, which I don't want.
I only need to make this code compile:
\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
\definemathcommand[xyz][nolop]{\newmcodes@
\kern\zeropoint\mfunction{fancy-function-name'*.:}}
\starttext
\xyz
\stoptext
How can I do that? The compilation fails at the \ifnum condition. Isn't
\ifnum a ConTeXt macro?

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%

\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'*.:}}
\definemathcommand[xyz][nolop]{\text{fancy-function-name'*.:}}
$\xyz^{\xyz}$

[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@
Dear list members, What is the ConTeXt equivalent of the LaTeX function \newmcodes@ defined in the AMSopn package (this function is used inside \DeclareMathOperator and \operatorname and has the effect of resetting text-mode punctuation characters such as *, -, /, :, and ’ in operator names)?
