Some math improvements
by Aditya Mahajan 25 May '07

25 May '07

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) 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... Aditya

yet another font installer
by Patrick Gundlach 25 May '07

25 May '07

Hi, I have just uploaded yet another font installer, similar to texfont, but only for opentype fonts and a bit limited. I never felt like reading the texfont manual, so I created my own frontend for the lcdf type tools. It works very well for me, so you might be interested. I have started a wiki page describing 'otfinst.rb' (I just see that I should use another name for it): <http://wiki.contextgarden.net/otfinst>. Enjoy!

mailarchive 2007?
by Patrick Gundlach 04 May '07

04 May '07

Hello everybody, anyone out there has a correct/full archive of the ntg-context mailinglist 2007 upto now? The one on <http://www.ntg.nl/pipermail/ntg-context/> has all '@' replaced by ' at ' which makes it hard to use for the mailinglist archive at contextgarden.net. While moving the archive to the new server, I have found out that because of a stupid misconfiguration the server didn't save the mails to the disk. Patrick

garden: filename capitalization
by Sanjoy Mahajan 26 Apr '07

26 Apr '07

Patrick, Can one stop the wiki upload from capitalizing the first letter of uploaded filenames? Case matters on most Unix systems (not sure about Mac OS X though), so for example a T-bib.tex won't be as much use as a t-bib.tex. -Sanjoy `Not all those who wander are lost.' (J.R.R. Tolkien)

"Improved" substack macro
by Aditya Mahajan 24 Apr '07

24 Apr '07

Hi Hans and Taco, The \startsubstack macro in core-mat places the subscript lower than the atop. See for example \startformula \sum_{\startsubstack a \NR b \NR \stopsubstack} \sum_{\scriptstyle a \atop \scriptstyle} \stopformula I have tried to get the correct spacing by copying what amsmath does. When you have time, can you look if it makes sense to provide both the substack macros. Aditya \def\startsubstackA {\vcenter\bgroup \baselineskip\fontdimen10 \scriptfont\plustwo \advance\baselineskip\fontdimen12 \scriptfont\plustwo \lineskip\plusthree\fontdimen8 \scriptfont\plusthree \lineskiplimit\lineskip \let\stopmathmode\relax \def\NC{\domatrixNC}% \def\MC{\domatrixNC\startmathmode}% \global\let\domatrixNC\dodomatrixNC \def\NR {\stopmathmode \global\let\domatrixNC\dodomatrixNC \crcr}% \mathsurround\zeropoint \everycr\emptytoks \halign\bgroup\hfil$\scriptstyle##$\hfil\crcr} \def\stopsubstackA {\crcr \egroup \egroup} \starttext \startformula \sum_{\startsubstack a \NR b \NR c \NR \stopsubstack} \sum_{a} \sum_{\startsubstackA a \NR b \NR c \NR \stopsubstackA} \sum_{\scriptstyle a \atop \scriptstyle b} \stopformula \stoptext
