373 "$class - Optional module dependency specifications (for module authors)",
376 Somewhere in your build-file (e.g. L<Module::Install>'s Makefile.PL):
380 configure_requires 'DBIx::Class' => '$distver';
384 my \$deploy_deps = $class->req_list_for ('deploy');

395 '=head1 DESCRIPTION',
397 Some of the less-frequently used features of L<DBIx::Class> have external
398 module dependencies on their own. In order not to burden the average user
399 with modules he will never use, these optional dependencies are not included
400 in the base Makefile.PL. Instead an exception with a descriptive message is
401 thrown when a specific feature is missing one or several modules required for
402 its operation. This module is the central holding place for the current list
403 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
406 '=head1 CURRENT REQUIREMENT GROUPS',
408 Dependencies are organized in C<groups> and each group can list one or more
409 required modules, with an optional minimum version (or 0 for any version).
410 The group name can be used in the
414 for my $group (sort keys %$reqs) {
415 my $p = $reqs->{$group}{pod}
418 my $modlist = $reqs->{$group}{req}
421 next unless keys %$modlist;
424 "=head2 $p->{title}",
427 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
429 "Requirement group: B<$group>",
435 '=head2 req_group_list',
437 '=item Arguments: none',
438 '=item Returns: \%list_of_requirement_groups',
441 This method should be used by DBIx::Class packagers, to get a hashref of all
442 dependencies keyed by dependency group. Each key (group name) can be supplied
443 to one of the group-specific methods below.
446 '=head2 req_list_for',
448 '=item Arguments: $group_name',
449 '=item Returns: \%list_of_module_version_pairs',
452 This method should be used by DBIx::Class extension authors, to determine the
453 version of modules a specific feature requires in the B<current> version of
454 DBIx::Class. See the L</SYNOPSIS> for a real-world
460 '=item Arguments: $group_name',
461 '=item Returns: 1|0',
464 Returns true or false depending on whether all modules required by
465 C<$group_name> are present on the system and loadable.
468 '=head2 req_missing_for',
470 '=item Arguments: $group_name',
471 '=item Returns: $error_message_string',
474 Returns a single line string suitable for inclusion in larger error messages.
475 This method would normally be used by DBIx::Class core-module author, to
476 indicate to the user that he needs to install specific modules before he will
477 be able to use a specific feature.
479 For example if some of the requirements for C<deploy> are not available,
480 the returned string could look like:
482 SQL::Translator >= $sqltver (see $class for details)
484 The author is expected to prepend the necessary text to this message before
485 returning the actual error seen by the user.
488 '=head2 req_errorlist_for',
490 '=item Arguments: $group_name',
491 '=item Returns: \%list_of_loaderrors_per_module',
494 Returns a hashref containing the actual errors that occured while attempting
495 to load each module in the requirement group.
