Using \cal, \frak, \goth in math mode

Using \cal, \frak, \goth in math mode

[Giuseppe Bilotta]

In ConTeXt, \cal, \frak and \goth (etc) are considered "text
only" commands. To use them in math mode one has to use
\gothing, \fraktur, \calligraphic etc, which make a temporary
switch to text mode. This is contrary to the LaTeX
expectations, where $\cal ABC$ makes all three letters
calligraphic. How could such a thing be achieved in ConTeXt?

I don't understand the problem.

$\cal ABC$ does make all three letters calligraphic in ConTeXt, at least in
my system.

{ \cg some text } should do it.

/S

Not in mine.

\starttext
$\cal ABC$
\stoptext

gives normal (math, italic) type ...

Could the problem have something to do with the version of the system?

I use pdfTeX Version 3.14159-14h-released-20010417 (Web2C 7.3.3.1) on SuSE
Linux 7.2 with ConTeXt ver: 2002.10.23.

By the way, this version of ConTeXt has a problem with  \angle in math mode:
the Acrobat Reader will complain of missing font when I use \angle.

I have version 2003.04.29. Yes, there have been many changes,
and along the fixes to your problems (you should upgrade!)
there have been also some changes in approach to font handling.

I'm not going to suggest a change in the core, since the
current approach seems to be the one preferred by Hans.
Rather, I'll implement the relative changes in a separate
module specifically designed for AMS-LaTeX compatibility.




Hans: there's a bug in your current implementation: in
font-ini.tex there's a line reading:

\def\caligraphic#1{\mathortext\mathtext\donothing{\cal #1}}

while it should read

\def\calligraphic#1{\mathortext\mathtext\donothing{\cal #1}}

(two ells)

changing it now would result in reverting to previous behavior, and then 
request for other behavior .. so we keep circling

We can make this configurable wong with more things (stable thingies can 
move to the newmath module (m-newmat) [my stepwise growing math module with 
configurable math; gb's not too latex specific goodies may go in there when 
approved -)]

[features like calligraphic are rather font dependent and currently can be 
configured by remapping fonts and families; tricky things]

ok done, also in mult-con?

We can discuss this in Hawaii, if you're coming there. BTW, I'm
now torn between presenting the math stuff (rather incomplete)
or presenting e-Omega 1.15--2.1, now that it seems to pass the
trip test. What would you suggest?

Haven't looked into it I must say :)

eomega would be fun esp if it could run a decent large job without problems

maybe there's room for two talks: math + a small e-omega one (i'll ask)
