For the Depends logic, I think the bleh-or-blah would not be a very
common occurance. More often (at least in the situations I can think
of) is "bleh only if [something]" *or* "blah only if not [something]".
Having to conjure up a "nox" package just to make the logic work
bothers me. But if people think if/then/else is the way to go...
As to the variant value syntax, we also need to get these variant
values into Package and into *Script fields. It seems pretty confusing
that "perl" has a sepcial meaning anywhere, and I think that string
might be prone to appear in scripts so we'd need something else there.
I'd rather keep a uniform syntax everywhere in .info. Maintainers
already know about percent expansion so I went with it. Consider:
Package: foo%type[nox]
Type: nox (-nox "") # one variant has "-nox", the other ""
Depends: (%type[nox] "") x11
CompileScript: <<
if [ %type[nox] == "-nox" ]; then
./configure %c --without-x11
else
./configure %c --with-x11
fi
make
