I also still think thatif we default in some way to generating a Makefile.PL, create_makefile_plshould be extended to have an explicit "skip" option as well.Definitely. I'd just change the default to 'auto' (which means create a 'small' [or 'passthrough'] Makefile.PL if none already exists) though, and then the author can explicitly put "create_makefile_pl => 0" (or any other false value) in their Build.PL to shut it off.If in the future we figure out how to auto-sense when we could create a 'traditional' Makefile.PL that would be cool, but I don't really see it happening. Too hard.-Ken
Attached below is a regexp-based solution that matches "simple" Build.PL files. I submit this just for thought, not necessarily for inclusion in M::B.
Inline below are the results of running my program against a bunch of CPAN packages. This demonstrates that many CPAN modules use "simple" Build.PL files. If (and that's a big if) we decided to use a code- matcher like what I've written, we could detect simple Build.PL files and decide on the fly if a "traditional" Makefile.PL is appropriate. Perhaps this mode could be triggered by C<create_makefile_pl => 'automatic'>
One could imagine that PPI would be a good tool to perform this code analysis.
