Well, the nath catcodes only apply in math mode, and indeed in math mode , will trigger \@comma :)

Hm, not here...

About \dots: with the nath module, \dots will *in math mode* use \cdots in all cases *except* after punctuation (e.g. after a comma); indeed, the code

\[ a=b, \dots c=d \dots \]

will give you \ldots in the first case and \cdots in the second case. Do you have some example of when it doesn't work?

Your example above renders with \cdots for both \dots. \usemodule[nath] \starttext $a, b, \dots, n$ \[ a=b, \dots c=d \dots \] \stoptext The first line is my old test case, the second is yours...both render with \cdots everywhere. Totally weird. I'm using the latest context from the pragma-ade page.

\def\over{\ifmmode\n@err{Disabled command \string\over } {No more a valid command. Replace {A \over B} with \frac A B.}\else\o@over\fi} \def\atop{\ifmmode\n@err{Disabled command \string\atop } {No more a valid command. Use array instead.}\else\o@atop\fi} \def\choose{\ifmmode\n@err{Disabled command \string\choose } {No more a valid command. Replace {A \choose B} with \binom A B.}\else\o@choose\fi}

Weird indeed. I'm not using the latest ConTeXt. (Actually I'm quite back with the updates ... gotta get down to it.) I'll see if upgrading gives me the same problem and in case get a fix.

OK.

Ah, of course... nikolai

It works like that? Excellent.

It seems I spoke too soon. It does in fact not work. \o@over can't be put like that inside the if-statement. A suggestion would be to re-work the whole section and instead make it \appendtoks \def\over{\n@err{Disabled command \string\over } {No more a valid command. Replace {A \string\over B} with \string\frac A B.}} \def\atop{\n@err{Disabled command \string\atop } {No more a valid command. Use array instead.}} \def\choose{\n@err{Disabled command \string\choose } {No more a valid command. Replace {A \string\choose B} with \string\binom A B. >>> }} \to\everymath but I don't know if that's a good solution. It forces you to use \string\over in the second argument to \n@err which I don't understand why, but otherwise TeX runs out of stack space. I suppose it's being expanded even though it shouldn't be. 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);}

Me too.

[Example]

Argh, that doesn't happen here...

This is pdfeTeX, Version 3.141592-1.20a-rc4-2.1 (MiKTeX 2.4)

pdfeTeX (Web2C 7.4.5) 3.14159-1.10b-2.1 I run latest tetex.

It seems I spoke too soon. It does in fact not work.

In the meantime, I'm thinking along the lines of something like

\def\over{% \ifmmode\n@err{Disabled command \string\over } {No more a valid command. Replace {A \over B} with \frac A B.}% \let\next\relax \else\let\next\o@over\fi\next} \def\atop{% \ifmmode\n@err{Disabled command \string\atop } {No more a valid command. Use array instead.}% \let\next\relax \else\let\next\o@atop\fi\next} \def\choose{% \ifmmode\n@err{Disabled command \string\choose } {No more a valid command. Replace {A \choose B} with \binom A B.}% \lext\next\relax \else\let\next\o@choose\fi\next}

which should be robust enough. Can you try it in the context where my previous solution busted?

I don't remember what busted, but it looks good. It works for my thesis, which is weird because you misspelled a \let (\lext) and it still worked fine. Furthermore, nested parentheses and stuff that produces implicit parentheses don't scale correctly. In fact, \left and \right don't seem to work either: \usemodule[nath] \starttext \[ (\frac{a}{b})^2 \] versus \[ \left(\frac{a}{b}\right)^2 \] \stoptext ..., 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);}
