Hi, please consider the following minimal example:
\def\before{\dodoubleempty\dobefore}% \def\dobefore[#1][#2]{before} \starttext \before[] after (should be: \before[]\ after without explicit \type{\ })\par \before[]after\par \before[][] after\par % this works \before[][]after\par \stoptext How can I prevent gobbling the following space, when the second optional argument is not given (i.e. first line). The macro itself should not insert space if the command is followed by any other character (2nd and 4th line). Thanks, Florian ___________________________________________________________________________________ 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 : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
