Now how would I go if I want to display the third argument in case it's
supplied and the first in case arg3 is empty?
It's not very easy. The best I could come up was the following:
@c use arg1 if present, otherwise use arg2
@macro choosearg{arg1, arg2}
@set dummyflag
@inlineifclear{dummyflag\arg1\, \arg1\}
@inlineifset{dummyflag\arg1\, \arg2\}
@end macro
I tested that this works with spaces in the arguments, but this
doesn't work if arg1 has any @-commands in it: this could be avoided
if the node names don't have @-commands in them.
Thank you very much for your fast answer, there won't be any @-command
in the arguments so your solution should work in principle.
Unfortunately, in the mean time I found out that I was unable to
generate valid tex output with this macro. The @myref macro is used
within a @deftypefn block environment and, while running texi2dvi, I get
an error similar to the one mentioned in [1], something like "Paragraph
ended before @deftypefn was complete".
So this approach for partly aliasing the @*ref macros doesn't look like
the right one. I guess I'll need to preprocess my texi strings based on
the output format. Or is there another way?
