346 '=head1 DESCRIPTION',
348 Some of the less-frequently used features of L<DBIx::Class> have external
349 module dependencies on their own. In order not to burden the average user
350 with modules he will never use, these optional dependencies are not included
351 in the base Makefile.PL. Instead an exception with a descriptive message is
352 thrown when a specific feature is missing one or several modules required for
353 its operation. This module is the central holding place for the current list
354 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
357 '=head1 CURRENT REQUIREMENT GROUPS',
359 Dependencies are organized in C<groups> and each group can list one or more
360 required modules, with an optional minimum version (or 0 for any version).
361 The group name can be used in the
365 for my $group (sort keys %$reqs) {
366 my $p = $reqs->{$group}{pod}
369 my $modlist = $reqs->{$group}{req}
372 next unless keys %$modlist;
375 "=head2 $p->{title}",
378 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
380 "Requirement group: B<$group>",
386 '=head2 req_group_list',
388 '=item Arguments: $none',
389 '=item Returns: \%list_of_requirement_groups',
392 This method should be used by DBIx::Class packagers, to get a hashref of all
393 dependencies keyed by dependency group. Each key (group name) can be supplied
394 to one of the group-specific methods below.
397 '=head2 req_list_for',
399 '=item Arguments: $group_name',
400 '=item Returns: \%list_of_module_version_pairs',
403 This method should be used by DBIx::Class extension authors, to determine the
404 version of modules a specific feature requires in the B<current> version of
405 DBIx::Class. See the L</SYNOPSIS> for a real-world
411 '=item Arguments: $group_name',
412 '=item Returns: 1|0',
414 'Returns true or false depending on whether all modules required by C<$group_name> are present on the system and loadable',
416 '=head2 req_missing_for',
418 '=item Arguments: $group_name',
419 '=item Returns: $error_message_string',
422 Returns a single line string suitable for inclusion in larger error messages.
423 This method would normally be used by DBIx::Class core-module author, to
424 indicate to the user that he needs to install specific modules before he will
425 be able to use a specific feature.
427 For example if some of the requirements for C<deploy> are not available,
428 the returned string could look like:
430 SQL::Translator >= $sqltver (see $class for details)
432 The author is expected to prepend the necessary text to this message before
433 returning the actual error seen by the user.
436 '=head2 req_errorlist_for',
438 '=item Arguments: $group_name',
439 '=item Returns: \%list_of_loaderrors_per_module',
442 Returns a hashref containing the actual errors that occured while attempting
443 to load each module in the requirement group.
