305 "$class - Optional module dependency specifications (for module authors)",
306 '=head1 SYNOPSIS (EXPERIMENTAL)',
308 B<THE USAGE SHOWN HERE IS EXPERIMENTAL>
310 Somewhere in your build-file (e.g. L<Module::Install>'s Makefile.PL):
314 configure_requires 'DBIx::Class' => '$distver';
318 my \$deploy_deps = $class->req_list_for ('deploy');
320 for (keys %\$deploy_deps) {
321 requires \$_ => \$deploy_deps->{\$_};
326 Note that there are some caveats regarding C<configure_requires()>, more info
327 can be found at L<Module::Install/configure_requires>
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_list_for',
371 '=item Arguments: $group_name',
372 '=item Returns: \%list_of_module_version_pairs',
375 This method should be used by DBIx::Class extension authors, to determine the
376 version of modules a specific feature requires in the B<current> version of
377 DBIx::Class. See the L<SYNOPSIS|/SYNOPSIS (EXPERIMENTAL)> for a real-world
383 '=item Arguments: $group_name',
384 '=item Returns: 1|0',
386 'Returns true or false depending on whether all modules required by C<$group_name> are present on the system and loadable',
388 '=head2 req_missing_for',
390 '=item Arguments: $group_name',
391 '=item Returns: $error_message_string',
394 Returns a single line string suitable for inclusion in larger error messages.
395 This method would normally be used by DBIx::Class core-module author, to
396 indicate to the user that he needs to install specific modules before he will
397 be able to use a specific feature.
399 For example if the requirements for C<replicated> are not available, the
400 returned string would look like:
402 Moose >= 0.98, MooseX::Types >= 0.21, namespace::clean (see $class for details)
404 The author is expected to prepend the necessary text to this message before
405 returning the actual error seen by the user.
408 '=head2 req_errorlist_for',
410 '=item Arguments: $group_name',
411 '=item Returns: \%list_of_loaderrors_per_module',
414 Returns a hashref containing the actual errors that occured while attempting
415 to load each module in the requirement group.
