364 "$class - Optional module dependency specifications (for module authors)",
367 Somewhere in your build-file (e.g. L<Module::Install>'s Makefile.PL):

386 '=head1 DESCRIPTION',
388 Some of the less-frequently used features of L<DBIx::Class> have external
389 module dependencies on their own. In order not to burden the average user
390 with modules he will never use, these optional dependencies are not included
391 in the base Makefile.PL. Instead an exception with a descriptive message is
392 thrown when a specific feature is missing one or several modules required for
393 its operation. This module is the central holding place for the current list
394 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
397 '=head1 CURRENT REQUIREMENT GROUPS',
399 Dependencies are organized in C<groups> and each group can list one or more
400 required modules, with an optional minimum version (or 0 for any version).
401 The group name can be used in the
405 for my $group (sort keys %$reqs) {
406 my $p = $reqs->{$group}{pod}
409 my $modlist = $reqs->{$group}{req}
412 next unless keys %$modlist;
415 "=head2 $p->{title}",
418 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
420 "Requirement group: B<$group>",
426 '=head2 req_group_list',
428 '=item Arguments: none',
429 '=item Returns: \%list_of_requirement_groups',
432 This method should be used by DBIx::Class packagers, to get a hashref of all
433 dependencies keyed by dependency group. Each key (group name) can be supplied
434 to one of the group-specific methods below.
437 '=head2 req_list_for',
439 '=item Arguments: $group_name',
440 '=item Returns: \%list_of_module_version_pairs',
443 This method should be used by DBIx::Class extension authors, to determine the
444 version of modules a specific feature requires in the B<current> version of
445 DBIx::Class. See the L</SYNOPSIS> for a real-world
451 '=item Arguments: $group_name',
452 '=item Returns: 1|0',
455 Returns true or false depending on whether all modules required by
456 C<$group_name> are present on the system and loadable.
459 '=head2 req_missing_for',
461 '=item Arguments: $group_name',
462 '=item Returns: $error_message_string',
465 Returns a single line string suitable for inclusion in larger error messages.
466 This method would normally be used by DBIx::Class core-module author, to
467 indicate to the user that he needs to install specific modules before he will
468 be able to use a specific feature.
470 For example if some of the requirements for C<deploy> are not available,
471 the returned string could look like:
473 SQL::Translator >= $sqltver (see $class for details)
475 The author is expected to prepend the necessary text to this message before
476 returning the actual error seen by the user.
479 '=head2 req_errorlist_for',
481 '=item Arguments: $group_name',
482 '=item Returns: \%list_of_loaderrors_per_module',
485 Returns a hashref containing the actual errors that occured while attempting
486 to load each module in the requirement group.
