I have an environment that I've defined as follows:


The problem is that I need to expand #2 before passing it to listSkeleton. It's okay if #1 is expanded (I think). I know I have to use \expandafter in some way, but not exactly how.

    Do you need to expand it only once or completely? – Martin Scharrer Aug 18 '11 at 9:54
  • @Martin Scharrer: I'm not familiar enough with LaTeX to comment on that. If expanding it completely is easier and doesn't break anything, then that will suffice. – gablin Aug 18 '11 at 11:35

If it is OK to expand it completely, not just once you can use \edef with a temporary macro:


If you really only want to expand it once you can do:


Often the macro \@tempa is used for such temparary assignments, but in user documents it requires \makeatletter ... \makatother around the code. So for simplicity I just used \temp. It is anyway just used inside a group.

  • In the first code there is a \noexpand missing, right before \begin. Otherwise the \edef will not work. – user2574 Aug 18 '11 at 10:33
  • @Axel: Yes, indeed. I overlooked that. Fixed now. – Martin Scharrer Aug 18 '11 at 10:42
