RE: Why does one work ant the other doesn't $(foreach

None of the above are syntactically correct examples.  Please always
provide a _WORKING_ example (unless it requires a huge
infrastructure--in which case please trim it), rather than a non-working
paraphrasing.  It requires significantly more work for us to reproduce
the problem if your example is not complete.

Please read: http://www.catb.org/~esr/faqs/smart-questions.html


Of the above, only the second one fails for me; the first and third work
fine.  Please provide a complete example of the failure in the third
case if you want us to look at it.

The second one fails because, like all functions etc., while leading
whitespace is stripped trailing whitespace is preserved.  That means
that the loop variable in the foreach function is not "var", but rather
"var    ".  So any reference to $(var) in the loop body will evaluate to
empty.

I agree that this is probably not worth supporting: please file an
enhancement request in the Savannah project to get this changed.  It
won't be changed for 3.81 though; it's too late for that now.
