Hi all,
I'm trying to define a macro \Command which can either have four or
five arguments. If it has five, I want to define them as
\Command1[#1][#2][#3][#4]{#5}
if it has four, as
\Command2[#1][#2][#3]{4#}
I thought this would be the way to go:
\def\Command{%
\doquadrupleempty\doCommand}
\def\doCommand{%
\iffifthargument%
\doquadrupleargument\Command1%
\else%
\dotripleargument\Command2%
\fi}
but that gives me errors about "too many }s". So I'm wondering: am I
on the wrong track? Can this be done at all?
Thanks, and best
Thomas

The above code is untested, but I am pretty sure that it will work.

Schmitz @ 2008-09-04 7:39 UTC (permalink / raw) To: mailing list for ConTeXt users Aditya, Peter, as always, thanks a lot for your help. Peter, you're certainly right that it's difficult to diagnose my problem - I'm sending only snippets, no example. But it's a fairly complex thing here for my presentation module and difficult to reduce in size. On Sep 3, 2008, at 6:58 PM, Aditya Mahajan wrote: > On Wed, 3 Sep 2008, Thomas A.

When I define \doCommand[#1][#2][#3][#4]#5 and then have \Command2[#1][#2][#3]#4 TeX picks up a closing bracket as #4. I suspect that my problem lies in the definition \doCommand[#1][#2][#3][#4]#5 . The two definitions don't match; when I look at \doCommand, the closing bracket is indeed argument #4, from TeX's point of view. Maybe I need to reverse the order of my arguments and make it \doCommand#1[#2][#3][#4][#5] ? but I'm not sure if this would play with quintupleempty... Anyway, thanks a lot for your help. I'll look further into it and will maybe come back with a real example later if I can't figure it out.

Also there is no need for a second parameter number check. How about something like \def\doCommand% {\iffifthargument \CommandA[#1][#2][#3][#4]{#5}% \else\iffourthargument \CommandB[#1][#2][#3]{#4}% \else % some error handling \fi \fi} Best wishes, Peter > Thanks, and best > > Thomas > ___________________________________________________________________________________ > If your question is of interest to others as well, please add an entry to the Wiki! > > maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context > webpage : http://www.pragma-ade.nl / http://tex.aanhet.net > archive : https://foundry.supelec.fr/projects/contextrev/ > wiki : http://contextgarden.net > ___________________________________________________________________________________ > ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 6+ messages in thread

That's the end of my suffering!! Thanks a lot, Wolfgang, you're my hero. Makes sense, too, now that I look at it. Now I'm gonna find out what \next does... Thanks!
