Dear list,
I’m trying to define a command that has a conditional argument:
\def\MyCommand#1#2#3{#1, #2, \doifemptyelse{#3}{#1}{#3}}
\starttext
\MyCommand{first}{second}
\stoptext
The problem is that \doifemtpyelse only works if there the third
argument is there as {}. And the third argument is actually an exception
to workaround an unwanted behavior of the command in very few
exceptional cases.
Is there no way to make \MyCommand above work with \doifemptyelse even
if its third argument is not defined?
Many thanks for your help,
Pablo
