779 "$class - Optional module dependency specifications (for module authors)",
782 Somewhere in your build-file (e.g. L<Module::Install>'s Makefile.PL):
786 configure_requires 'DBIx::Class' => '$distver';
790 my \$deploy_deps = $class->req_list_for('deploy');
792 for (keys %\$deploy_deps) {

801 '=head1 DESCRIPTION',
803 Some of the less-frequently used features of L<DBIx::Class> have external
804 module dependencies on their own. In order not to burden the average user
805 with modules he will never use, these optional dependencies are not included
806 in the base Makefile.PL. Instead an exception with a descriptive message is
807 thrown when a specific feature is missing one or several modules required for
808 its operation. This module is the central holding place for the current list
809 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
812 '=head1 CURRENT REQUIREMENT GROUPS',
814 Dependencies are organized in C<groups> and each group can list one or more
815 required modules, with an optional minimum version (or 0 for any version).
816 The group name can be used in the
820 for my $group (sort keys %$reqs) {
821 my $p = $reqs->{$group}{pod}
824 my $modlist = $reqs->{$group}{req}
827 next unless keys %$modlist;
830 "=head2 $p->{title}",
833 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
835 "Requirement group: B<$group>",
841 '=head2 req_group_list',
843 '=item Arguments: none',
844 '=item Return Value: \%list_of_requirement_groups',
847 This method should be used by DBIx::Class packagers, to get a hashref of all
848 dependencies keyed by dependency group. Each key (group name) can be supplied
849 to one of the group-specific methods below.
852 '=head2 req_list_for',
854 '=item Arguments: $group_name',
855 '=item Return Value: \%list_of_module_version_pairs',
858 This method should be used by DBIx::Class extension authors, to determine the
859 version of modules a specific feature requires in the B<current> version of
860 DBIx::Class. See the L</SYNOPSIS> for a real-world
866 '=item Arguments: $group_name',
867 '=item Return Value: 1|0',
870 Returns true or false depending on whether all modules required by
871 C<$group_name> are present on the system and loadable.
874 '=head2 req_missing_for',
876 '=item Arguments: $group_name',
877 '=item Return Value: $error_message_string',
880 Returns a single line string suitable for inclusion in larger error messages.
881 This method would normally be used by DBIx::Class core-module author, to
882 indicate to the user that he needs to install specific modules before he will
883 be able to use a specific feature.
885 For example if some of the requirements for C<deploy> are not available,
886 the returned string could look like:
888 SQL::Translator >= $sqltver (see $class for details)
890 The author is expected to prepend the necessary text to this message before
891 returning the actual error seen by the user.
894 '=head2 die_unless_req_ok_for',
896 '=item Arguments: $group_name',
899 Checks if L</req_ok_for> passes for the supplied C<$group_name>, and
900 in case of failure throws an exception including the information
901 from L</req_missing_for>.
904 '=head2 req_errorlist_for',
906 '=item Arguments: $group_name',
907 '=item Return Value: \%list_of_loaderrors_per_module',
910 Returns a hashref containing the actual errors that occurred while attempting
911 to load each module in the requirement group.
