405 '=head1 DESCRIPTION',
407 Some of the less-frequently used features of L<DBIx::Class> have external
408 module dependencies on their own. In order not to burden the average user
409 with modules he will never use, these optional dependencies are not included
410 in the base Makefile.PL. Instead an exception with a descriptive message is
411 thrown when a specific feature is missing one or several modules required for
412 its operation. This module is the central holding place for the current list
413 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
416 '=head1 CURRENT REQUIREMENT GROUPS',
418 Dependencies are organized in C<groups> and each group can list one or more
419 required modules, with an optional minimum version (or 0 for any version).
420 The group name can be used in the
424 for my $group (sort keys %$reqs) {
425 my $p = $reqs->{$group}{pod}
428 my $modlist = $reqs->{$group}{req}
431 next unless keys %$modlist;
434 "=head2 $p->{title}",
437 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
439 "Requirement group: B<$group>",
445 '=head2 req_group_list',
447 '=item Arguments: none',
448 '=item Returns: \%list_of_requirement_groups',
451 This method should be used by DBIx::Class packagers, to get a hashref of all
452 dependencies keyed by dependency group. Each key (group name) can be supplied
453 to one of the group-specific methods below.
456 '=head2 req_list_for',
458 '=item Arguments: $group_name',
459 '=item Returns: \%list_of_module_version_pairs',
462 This method should be used by DBIx::Class extension authors, to determine the
463 version of modules a specific feature requires in the B<current> version of
464 DBIx::Class. See the L</SYNOPSIS> for a real-world
470 '=item Arguments: $group_name',
471 '=item Returns: 1|0',
474 Returns true or false depending on whether all modules required by
475 C<$group_name> are present on the system and loadable.
478 '=head2 req_missing_for',
480 '=item Arguments: $group_name',
481 '=item Returns: $error_message_string',
484 Returns a single line string suitable for inclusion in larger error messages.
485 This method would normally be used by DBIx::Class core-module author, to
486 indicate to the user that he needs to install specific modules before he will
487 be able to use a specific feature.
489 For example if some of the requirements for C<deploy> are not available,
490 the returned string could look like:
492 SQL::Translator >= $sqltver (see $class for details)
494 The author is expected to prepend the necessary text to this message before
495 returning the actual error seen by the user.
498 '=head2 req_errorlist_for',
500 '=item Arguments: $group_name',
501 '=item Returns: \%list_of_loaderrors_per_module',
504 Returns a hashref containing the actual errors that occured while attempting
505 to load each module in the requirement group.
