Font question mfonts.pdf manual

[WN]

Hi,

I am reading the mfonts.pdf manual to understand more about Context font 
mechanism.
In section 10 Math collection, Hans writes

"Math is a complicated matter and therefore we will not spend that many 
words on the gory details ..
.....
More information can be found in the documentation of the math module"

First question is : Why do you not spend more words on this subject ?

I suppose a lot of Latex users are possibly interested
in using Context for their math typesetting but not knowing all the gory 
details,
will complicate matters and hinder a possible conversion from Latex to 
Context.

Second question is : where can I find the documentation of the  math 
module ? Is it in PDF or do I
need to consult math-ini.tex ?

Kind regards

Wim Neimeijer

setting up math fonts is normally not something that a user does: there 
is a limited amount of math fonts and they are normally supported 
out-of-the-box

it depends on how many users want to define math symbols, make math font 
metrics (no fun) etc

in most cases there should beno problem to go from latex to context 
because symbolic names are used for math symbols and resolving them is a 
low level (hidden) activity.

taco and i will make a manual for math (the built in features) some day 
soon - we will use a special font for that which is work in progress

I use a lot of mathematics i.e a lot of integral symbols (\oint, \oiint, 
\oiiint ) for my documentation.
I could not find the corresponding Context math symbols. I suppose they 
are not defined as yet ?

Furthermore I use a small tex module written by David Munger and which I 
posted
on this newsgroup a couple of days ago to define some of these math 
symbols.
I was wondering can one switch back and forth using the mechanism of

\enablemathcollection[collection 1]
\usemathcollection[collection 1]

Some math .....

\enablemathcollection[collection 2]
\usemathcollection[collection 2]

Some math .....

Thanks for the help

Kind regards

No, they are not. I already noticed this question last time, but
didn't know how to answer it.

The main problem is that not only the symbols: not even the proper
font is defined. \oiint resides in "pxexa" font, which is mapped to
Palatino-Math-Extension-A, but that font is not mapped any further.

It would be nice to "define" (copy definitions from LaTeX) those
amsmath symbols once anyway (probably the first time when someone will
need them). An example of such a definition would be:

\definemathsymbol [boxdot]     [bin]  [ma] ["00]

(copied from \re@DeclareMathSymbol{\boxdot}{\mathbin}{AMSa}{0} in pxfonts.sty)

After that you can use $\boxdot$.

But this font is mapped to "ma", while I have no idea which steps are
needed to do the same for "Math-Extension-A" fonts. In order to make
yout integral signs work, you have to ask Adam/Taco/Hans for font
definitions first.

After that you will need the following two definitions:

\definemathsymbol [oiintop]      [op]  [m?] ["10]
\definemathsymbol [oiiintop]     [op]  [m?] ["51]

\definemathcommand [oiint]    {\oiintop\nolimits}
\definemathcommand [oiiint]   {\oiiintop\nolimits}

PS for Hans: regarding the math definitions: are the two functions
general enough to deserve two lines in math-tex?

\definemathcommand [erf]  [nolop] {\mfunction{erf}}
\definemathcommand [erfc] [nolop] {\mfunction{erfc}}
