Example from a CPAN distribution: features( 'Lower case API' => [ -default => 0, 'capitalization' => '0.03', ], 'Schema generation' => [ -default => 1, 'DBIx::DBSchema' => '', 'Class::Accessor' => '', ], ); auto_install(); If capitalization module is not installed on author's system then it's not listed in META.yml and listed if installed. MYMETA is not affected. -- Best regards, Ruslan.

This is intentional, and it the precise reason why META.yml is considered advisory and MYMETA.yml is considered authorative when it comes to dependencies. Adam K On 21 May 2011 02:50, Ruslan Zakirov via RT <bug-Module-Install@rt.cpan.org> wrote: Show quoted text

Hello Adam, May be I was not clear. Problem I was describing is that content of META.yml file depends on configuration of author's system. Don't mind module X to be listed in META.yml even if it's optional requirement. I just believe it should be there all the time even if author has no this module at the moment.

This is indeed intentional. Because configuration via Makefile.PL is turing-complete, there's absolutely nothing that can be done to avoid differing dependencies. For example, some modules need different modules on Windows and Unix, the dep for the author will be the only one included. There's no good way to fix this, hence the need for MYMETA.yml. I think we are content with this situation to continue at the moment. Adam K On 24 May 2011 21:24, Ruslan Zakirov via RT <bug-Module-Install@rt.cpan.org> wrote: Show quoted text
