329 '=head1 DESCRIPTION',
331 Some of the less-frequently used features of L<DBIx::Class> have external
332 module dependencies on their own. In order not to burden the average user
333 with modules he will never use, these optional dependencies are not included
334 in the base Makefile.PL. Instead an exception with a descriptive message is
335 thrown when a specific feature is missing one or several modules required for
336 its operation. This module is the central holding place for the current list
337 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
340 '=head1 CURRENT REQUIREMENT GROUPS',
342 Dependencies are organized in C<groups> and each group can list one or more
343 required modules, with an optional minimum version (or 0 for any version).
344 The group name can be used in the
348 for my $group (sort keys %$reqs) {
349 my $p = $reqs->{$group}{pod}
352 my $modlist = $reqs->{$group}{req}
355 next unless keys %$modlist;
358 "=head2 $p->{title}",
361 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
363 "Requirement group: B<$group>",
369 '=head2 req_group_list',
371 '=item Arguments: $none',
372 '=item Returns: \%list_of_requirement_groups',
375 This method should be used by DBIx::Class packagers, to get a hashref of all
376 dependencies keyed by dependency group. Each key (group name) can be supplied
377 to one of the group-specific methods below.
380 '=head2 req_list_for',
382 '=item Arguments: $group_name',
383 '=item Returns: \%list_of_module_version_pairs',
386 This method should be used by DBIx::Class extension authors, to determine the
387 version of modules a specific feature requires in the B<current> version of
388 DBIx::Class. See the L</SYNOPSIS> for a real-world
394 '=item Arguments: $group_name',
395 '=item Returns: 1|0',
397 'Returns true or false depending on whether all modules required by C<$group_name> are present on the system and loadable',
399 '=head2 req_missing_for',
401 '=item Arguments: $group_name',
402 '=item Returns: $error_message_string',
405 Returns a single line string suitable for inclusion in larger error messages.
406 This method would normally be used by DBIx::Class core-module author, to
407 indicate to the user that he needs to install specific modules before he will
408 be able to use a specific feature.
410 For example if some of the requirements for C<deploy> are not available,
411 the returned string could look like:
413 SQL::Translator >= $sqltver (see $class for details)
415 The author is expected to prepend the necessary text to this message before
416 returning the actual error seen by the user.
419 '=head2 req_errorlist_for',
421 '=item Arguments: $group_name',
422 '=item Returns: \%list_of_loaderrors_per_module',
425 Returns a hashref containing the actual errors that occured while attempting
426 to load each module in the requirement group.
