240 "$class - Optional module dependency specifications",
241 '=head1 DESCRIPTION',
243 Some of the less-frequently used features of L<DBIx::Class> have external
244 module dependencies on their own. In order not to burden the average user
245 with modules he will never use, these optional dependencies are not included
246 in the base Makefile.PL. Instead an exception with a descriptive message is
247 thrown when a specific feature is missing one or several modules required for
248 its operation. This module is the central holding place for the current list
249 of such dependencies.
251 '=head1 CURRENT REQUIREMENT GROUPS',
253 Dependencies are organized in C<groups> and each group can list one or more
254 required modules, with an optional minimum version (or 0 for any version).
255 The group name can be used in the
259 for my $group (sort keys %$reqs) {
260 my $p = $reqs->{$group}{pod}
263 my $modlist = $reqs->{$group}{req}
266 next unless keys %$modlist;
269 "=head2 $p->{title}",
272 ( map { "=item * $_" . ($modlist->{$_} ? " >= $modlist->{$_}" : '') } (sort keys %$modlist) ),
274 "Requirement group: B<$group>",
280 '=head2 req_list_for',
282 '=item Arguments: $group_name',
283 '=item Returns: \%list_of_module_version_pairs',
286 This method should be used by DBIx::Class extension authors, to determine the
287 version of modules which a specific feature requires in the current version of
288 DBIx::Class. For example if you write a module/extension that requires
289 DBIx::Class and also requires the availability of
290 L<DBIx::Class::Storage::DBI/deploy>, you can do the following in your
291 C<Makefile.PL> or C<Build.PL>
294 my \$dep_list = $class->req_list_for ('deploy');
296 Which will give you a list of module/version pairs necessary for the particular
297 feature to function with this version of DBIx::Class.
302 '=item Arguments: $group_name',
303 '=item Returns: 1|0',
305 'Returns true or false depending on whether all modules required by $group_name are present on the system and loadable',
307 '=head2 req_missing_for',
309 '=item Arguments: $group_name',
310 '=item Returns: $error_message_string',
313 Returns a single line string suitable for inclusion in larger error messages.
314 This method would normally be used by DBIx::Class core-module author, to
315 indicate to the user that he needs to install specific modules before he will
316 be able to use a specific feature.
318 For example if the requirements for C<replicated> are not available, the
319 returned string would look like:
321 Moose >= 0.98, MooseX::Types >= 0.21, namespace::clean (see $class for details)
323 The author is expected to prepend the necessary text to this message before
324 returning the actual error seen by the user.
327 '=head2 req_errorlist_for',
329 '=item Arguments: $group_name',
330 '=item Returns: \%list_of_loaderrors_per_module',
333 Returns a hashref containing the actual errors that occured while attempting
334 to load each module in the requirement group.
