nath and \(start|stop)formula

Hi! I just began testing the 2.99.1.20041026 release of tetex and nath is acting up. In the following document, the first math-formula works fine, but the second one (display) doesn't: \usemodule[nath] \starttext $A = (B, C, D, E)$ \placeformula \startformula A = (B, C, D, E) \stopformula \stoptext ! Undefined control sequence. l.6 A = ( B, C, D, E) ? X Any ideas? I'm guessing that the activation of ( messes something up. If ( is changed to \{, the first , (after B) gives the same error. If I use $$ ... $$ instead of \startformula ... \stopformula, it seems to work fine though. nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

Try \startnathequation ... \stopnathequation instead. Or patch t-nath.tex for the same effect, I have (but this might have side-effects): \let\nath!startformula\startformula \let\nath!stopformula\stopformula \def\startnathequation{% \begingroup \curr@cr@is@wall@cr \nath!startformula \startnatheq \hbox\bgroup \dmathon@ \wall\mathopen{}% } \def\stopnathequation{% \return \dmathoff@ \egroup \stopnatheq \nath!stopformula \endgroup } \let\startformula\startnathequation \let\stopformula\stopnathequation regards, Christopher Creutzig

Ah, thanks. Is there still a way to get unnumbered equations? nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

Do not put \placeformula before the equation :) -- Giuseppe "Oblomov" Bilotta

Well, that changes a bit the spacing, how about \placeformula[-] ? Tobias

New subject: "[" at beginning of formula ?

Hello, I'd like to typeset [\partial,B]=0 but \starttext \placeformula \startformula 0= [ A ,B ] = 0 \stopformula gives just "=0" (see below) while \stoptext \starttext \placeformula \startformula 0= [ A ,B ] \stopformula \stoptext works. What is the meaning of [ at the beginning of a formula, and how do I get rid of it? Matthias

Hi Matthias, Despite Hans' suggestion of putting \relax in front of [, in my installation of ConTeXt this works well: \starttext \startformula 0 =[\partial,B] =0. \stopformula Make sure there is no funny invisible characters in front of the square brackets. Best regards: OK

Hi Otared, the actual problem arises with \starttext \startformula [A,B] =0. \stopformula \stoptext or, even worse, with \starttext \startformula [\partial,B] =0. \stopformula \stoptext Hans' solution is to use \relax whenever one has a [ at the beginning of a formula: \starttext \startformula \relax [\partial,B] =0. \stopformula \stoptext Matthias On Nov 17, 2004, at 5:35 AM, Otared Kavian wrote:

Hi Matthias, Yes are right, indeed... However I tried the following which works as well (replacing \relax with empty braces {}): \starttext \startformula {}[\partial,B] =0. \stopformula and \startformula {}[A,B] =0. \stopformula \stoptext Best regards: OK
