Hi Hans and Taco,
I am attaching the math enhancements that I have been promising for about for some days^H^H^H^Hweeks now. Here are the changes.
1. Improved \llap, \rlap, \clap that work in both math and text mode (Taco's code)
2. A \cramped macro to go into cramped mode (based on Knuth's code) made even more cramped:
\def\docramped#1#2% {\begingroup % added HH, made even more cramped \setbox\scratchbox\hbox {\nulldelimiterspace\zeropoint $\m@th#1\radical\zerocount{#2}$}% \ht\scratchbox-\dimexpr \ifx#1\displaystyle \fontdimen8\textfont3 +.25\fontdimen5\textfont2 \else 1.25\fontdimen8 \ifx#1\textstyle \textfont \else\ifx#1\scriptstyle \scriptfont \else \scriptscriptfont \fi \fi \plusthree \fi -\ht\scratchbox \relax \box\scratchbox \endgroup}
3. \crampedllap \crampedrlap, \crampedclap for the equivalents to \llap etc which typesets its contents in cramped mode (well, I kinda figured that out on my own :)
4. An improved substack macro, with improved spacing. (Based on amsmath's substack macro). Taco, does it make sense to surround substack with a group, which will save some typing \sum_startsubstack whatever \stopsubstack or are there any side effects? In the code, I do not have the extra group.
5. Definitions for iint, iiint, iiiint (for those who can't count i's like me, you can use \repeatintegral{1}, \repeatintegral{2}, etc. Maybe, we should have the more readable \doubleintegral, \tripeintegral, \quadintegral also). This is based on amsmath code, and tries to use correct spacing for \iint\limits_{....}. BTW, does anyone wish that the limits with \int were configurable rather than defaulting to \nolimits? amsmath provides this feature, but I have personally never seen it being used. It is not too difficult to implement.
6. A definition for splitfrac, which is useful for multi-line fractions. Based on Michael Downes' code.
..... I also had something for \intertext, but realized that \intertext does not honor indentations. I will look into that first, before posting the code.
Now, I need to do collect everthing for theorems. Hopefully, core-des has not changed since I started working on it...
i wonder is this genfrac is ok ... dangling \zeropoint etc can you check m-newmath? maybe the few useful things in there can go to core-mat anyway Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
