582 "$class - Optional module dependency specifications (for module authors)",

604 '=head1 DESCRIPTION',
606 Some of the less-frequently used features of L<DBIx::Class> have external
607 module dependencies on their own. In order not to burden the average user
608 with modules he will never use, these optional dependencies are not included
609 in the base Makefile.PL. Instead an exception with a descriptive message is
610 thrown when a specific feature is missing one or several modules required for
611 its operation. This module is the central holding place for the current list
612 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
615 '=head1 CURRENT REQUIREMENT GROUPS',
617 Dependencies are organized in C<groups> and each group can list one or more
618 required modules, with an optional minimum version (or 0 for any version).
619 The group name can be used in the
623 for my $group (sort keys %$reqs) {
624 my $p = $reqs->{$group}{pod}
627 my $modlist = $reqs->{$group}{req}
630 next unless keys %$modlist;
633 "=head2 $p->{title}",
636 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
638 "Requirement group: B<$group>",
644 '=head2 req_group_list',
646 '=item Arguments: none',
647 '=item Returns: \%list_of_requirement_groups',
650 This method should be used by DBIx::Class packagers, to get a hashref of all
651 dependencies keyed by dependency group. Each key (group name) can be supplied
652 to one of the group-specific methods below.
655 '=head2 req_list_for',
657 '=item Arguments: $group_name',
658 '=item Returns: \%list_of_module_version_pairs',
661 This method should be used by DBIx::Class extension authors, to determine the
662 version of modules a specific feature requires in the B<current> version of
663 DBIx::Class. See the L</SYNOPSIS> for a real-world
669 '=item Arguments: $group_name',
670 '=item Returns: 1|0',
673 Returns true or false depending on whether all modules required by
674 C<$group_name> are present on the system and loadable.
677 '=head2 req_missing_for',
679 '=item Arguments: $group_name',
680 '=item Returns: $error_message_string',
683 Returns a single line string suitable for inclusion in larger error messages.
684 This method would normally be used by DBIx::Class core-module author, to
685 indicate to the user that he needs to install specific modules before he will
686 be able to use a specific feature.
688 For example if some of the requirements for C<deploy> are not available,
689 the returned string could look like:
691 SQL::Translator >= $sqltver (see $class for details)
693 The author is expected to prepend the necessary text to this message before
694 returning the actual error seen by the user.
697 '=head2 req_errorlist_for',
699 '=item Arguments: $group_name',
700 '=item Returns: \%list_of_loaderrors_per_module',
703 Returns a hashref containing the actual errors that occured while attempting
704 to load each module in the requirement group.
