1234 not being available on a sufficient portion of production installations of
1235 Perl. Robust support for such dependency requirements is available in the
1236 L<CPAN> installer only since version C<1.94_56> first made available for
1237 production with perl version C<5.12>. It is the belief of the current
1238 maintainer that support for requirements during the C<configure> build phase
1239 will not be sufficiently ubiquitous until the B<year 2020> at the earliest,
1240 hence the extra care demonstrated above. It should also be noted that some
1241 3rd party installers (e.g. L<cpanminus|App::cpanminus>) do the right thing
1242 with configure requirements independent from the versions of perl and CPAN
1248 #@@ DESCRIPTION HEADING
1250 push @chunks, <<'EOC';
1253 Some of the less-frequently used features of L<DBIx::Class> have external
1254 module dependencies on their own. In order not to burden the average user
1255 with modules they will never use, these optional dependencies are not included
1256 in the base Makefile.PL. Instead an exception with a descriptive message is
1257 thrown when a specific feature can't find one or several modules required for
1258 its operation. This module is the central holding place for the current list
1259 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
1262 Dependencies are organized in L<groups|/CURRENT REQUIREMENT GROUPS> where each
1263 group can list one or more required modules, with an optional minimum version
1264 (or 0 for any version). In addition groups prefixed with C<test_> can specify
1265 a set of environment variables, some (or all) of which are marked as required
1266 for the group to be considered by L</req_list_for>
1268 Each group name (or a combination thereof) can be used in the
1269 L<public methods|/METHODS> as described below.

1346 supplied to its C<import> method.
1348 =head2 -skip_all_without
1352 =item Arguments: @group_names
1356 A convenience wrapper for use during testing:
1359 push @chunks, " use $class -skip_all_without => qw(admin test_rdbms_mysql);";
1361 push @chunks, 'Roughly equivalent to the following code:';

1376 It also takes into account the C<RELEASE_TESTING> environment variable and

1378 C<release_testing_mandatory>.
1384 =item Arguments: @group_names

1409 =head2 req_group_list
1413 =item Arguments: none
1415 =item Return Value: \%list_of_requirement_groups
1419 This method should be used by DBIx::Class packagers, to get a hashref of all
1420 dependencies B<keyed> by dependency group. Each key (group name), or a combination
1421 thereof (as an arrayref) can be supplied to the methods below.
1422 The B<values> of the returned hash are currently a set of options B<without a
1423 well defined structure>. If you have use for any of the contents - contact the
1424 maintainers, instead of treating this as public (left alone stable) API.
1430 =item Arguments: $group_name | \@group_names
1432 =item Return Value: \%set_of_module_version_pairs
1436 This method should be used by DBIx::Class extension authors, to determine the
1437 version of modules a specific set of features requires for this version of
1438 DBIx::Class (regardless of their availability on the system).
1439 See the L</SYNOPSIS> for a real-world example.
1441 When handling C<test_*> groups this method behaves B<differently> from
1442 L</modreq_list_for> below (and is the only such inconsistency among the
1443 C<req_*> methods). If a particular group declares as requirements some
1444 C<environment variables> and these requirements are not satisfied (the envvars
1445 are unset) - then the C<module requirements> of this group are not included in
1448 =head2 modreq_list_for
1452 =item Arguments: $group_name | \@group_names
1454 =item Return Value: \%set_of_module_version_pairs
1458 Same as L</req_list_for> but does not take into consideration any
1459 C<environment variable requirements> - returns just the list of required
1466 =item Arguments: $group_name | \@group_names
1468 =item Return Value: 1|0
1472 Returns true or false depending on whether all modules/envvars required by
1473 the group(s) are loadable/set on the system.
1475 =head2 req_missing_for
1479 =item Arguments: $group_name | \@group_names
1481 =item Return Value: $error_message_string
1485 Returns a single-line string suitable for inclusion in larger error messages.
1486 This method would normally be used by DBIx::Class core features, to indicate to
1487 the user that they need to install specific modules and/or set specific
1488 environment variables before being able to use a specific feature set.
1490 For example if some of the requirements for C<deploy> are not available,
1491 the returned string could look like:
1494 push @chunks, qq{ "SQL::Translator~>=$sqltver" (see $class documentation for details)};
1496 push @chunks, <<'EOC';
1497 The author is expected to prepend the necessary text to this message before
1498 returning the actual error seen by the user. See also L</modreq_missing_for>
1500 =head2 modreq_missing_for
1504 =item Arguments: $group_name | \@group_names
1506 =item Return Value: $error_message_string
1510 Same as L</req_missing_for> except that the error string is guaranteed to be
1511 either empty, or contain a set of module requirement specifications suitable
1512 for piping to e.g. L<cpanminus|App::cpanminus>. The method explicitly does not
1513 attempt to validate the state of required environment variables (if any).
1515 For instance if some of the requirements for C<deploy> are not available,
1516 the returned string could look like:
1519 push @chunks, qq{ "SQL::Translator~>=$sqltver"};
1521 push @chunks, <<'EOC';
1523 See also L</-list_missing>.
1529 =item Arguments: $group_name | \@group_names
1533 A convenience wrapper around L<skip|Test::More/SKIP>. It does not take neither
1534 a reason (it is generated by L</req_missing_for>) nor an amount of skipped tests
1535 (it is always C<1>, thus mandating unconditional use of
1536 L<done_testing|Test::More/done_testing>). Most useful in combination with ad hoc
1537 requirement specifications:
1540 push @chunks, <<EOC;
1542 $class->skip_without([ deploy YAML>=0.90 ]);
1548 push @chunks, <<'EOC';
1550 =head2 die_unless_req_ok_for
1554 =item Arguments: $group_name | \@group_names
1558 Checks if L</req_ok_for> passes for the supplied group(s), and
1559 in case of failure throws an exception including the information
1560 from L</req_missing_for>. See also L</-die_without>.
1562 =head2 modreq_errorlist_for
1566 =item Arguments: $group_name | \@group_names
1568 =item Return Value: \%set_of_loaderrors_per_module
1572 Returns a hashref containing the actual errors that occurred while attempting
1573 to load each module in the requirement group(s).
1575 =head2 req_errorlist_for
1577 Deprecated method name, equivalent (via proxy) to L</modreq_errorlist_for>.
