Hi, it seems that in spec files comments started with '#' sometimes work and sometimes don't work. For example, this line doesn't cause any problem: min-version = 2021a # due to _() but a line like the following does: gui-main = some_public_func # just this one Namely, I get an error saying unknown public function. But if I move the comment to a new line, everything works. Now, I can live with inline comments not being allowed there, but the error message is misleading and I'm not sure that the aim is really not to support comments, maybe this is just a side effect of some bug. thanks sven
