1276 not being available on a sufficient portion of production installations of
1277 Perl. Robust support for such dependency requirements is available in the
1278 L<CPAN> installer only since version C<1.94_56> first made available for
1279 production with perl version C<5.12>. It is the belief of the current
1280 maintainer that support for requirements during the C<configure> build phase
1281 will not be sufficiently ubiquitous until the B<year 2020> at the earliest,
1282 hence the extra care demonstrated above. It should also be noted that some
1283 3rd party installers (e.g. L<cpanminus|App::cpanminus>) do the right thing
1284 with configure requirements independent from the versions of perl and CPAN
1290 #@@ DESCRIPTION HEADING
1292 push @chunks, <<'EOC';
1295 Some of the less-frequently used features of L<DBIx::Class> have external
1296 module dependencies on their own. In order not to burden the average user
1297 with modules they will never use, these optional dependencies are not included
1298 in the base Makefile.PL. Instead an exception with a descriptive message is
1299 thrown when a specific feature can't find one or several modules required for
1300 its operation. This module is the central holding place for the current list
1301 of such dependencies, for DBIx::Class core authors, and DBIx::Class extension
1304 Dependencies are organized in L<groups|/CURRENT REQUIREMENT GROUPS> where each
1305 group can list one or more required modules, with an optional minimum version
1306 (or 0 for any version). In addition groups prefixed with C<test_> can specify
1307 a set of environment variables, some (or all) of which are marked as required
1308 for the group to be considered by L</req_list_for>
1310 Each group name (or a combination thereof) can be used in the
1311 L<public methods|/METHODS> as described below.

1388 supplied to its C<import> method.
1390 =head2 -skip_all_without

1398 A convenience wrapper for use during testing:

1451 =head2 req_group_list
1455 =item Arguments: none
1457 =item Return Value: \%list_of_requirement_groups
1461 This method should be used by DBIx::Class packagers, to get a hashref of all
1462 dependencies B<keyed> by dependency group. Each key (group name), or a combination
1463 thereof (as an arrayref) can be supplied to the methods below.
1464 The B<values> of the returned hash are currently a set of options B<without a
1465 well defined structure>. If you have use for any of the contents - contact the
1466 maintainers, instead of treating this as public (left alone stable) API.
1472 =item Arguments: $group_name | \@group_names
1474 =item Return Value: \%set_of_module_version_pairs
1478 This method should be used by DBIx::Class extension authors, to determine the
1479 version of modules a specific set of features requires for this version of
1480 DBIx::Class (regardless of their availability on the system).
1481 See the L</SYNOPSIS> for a real-world example.
1483 When handling C<test_*> groups this method behaves B<differently> from
1484 L</modreq_list_for> below (and is the only such inconsistency among the
1485 C<req_*> methods). If a particular group declares as requirements some
1486 C<environment variables> and these requirements are not satisfied (the envvars
1487 are unset) - then the C<module requirements> of this group are not included in
1490 =head2 modreq_list_for
1494 =item Arguments: $group_name | \@group_names
1496 =item Return Value: \%set_of_module_version_pairs
1500 Same as L</req_list_for> but does not take into consideration any
1501 C<environment variable requirements> - returns just the list of required
1508 =item Arguments: $group_name | \@group_names
1510 =item Return Value: 1|0
1514 Returns true or false depending on whether all modules/envvars required by
1515 the group(s) are loadable/set on the system.
1517 =head2 req_missing_for
1521 =item Arguments: $group_name | \@group_names
1523 =item Return Value: $error_message_string
1527 Returns a single-line string suitable for inclusion in larger error messages.
1528 This method would normally be used by DBIx::Class core features, to indicate to
1529 the user that they need to install specific modules and/or set specific
1530 environment variables before being able to use a specific feature set.
1532 For example if some of the requirements for C<deploy> are not available,
1533 the returned string could look like:
1536 push @chunks, qq{ "SQL::Translator~$sqltver" (see $class documentation for details)};
1538 push @chunks, <<'EOC';
1539 The author is expected to prepend the necessary text to this message before
1540 returning the actual error seen by the user. See also L</modreq_missing_for>
1542 =head2 modreq_missing_for
1546 =item Arguments: $group_name | \@group_names
1548 =item Return Value: $error_message_string
1552 Same as L</req_missing_for> except that the error string is guaranteed to be
1553 either empty, or contain a set of module requirement specifications suitable
1554 for piping to e.g. L<cpanminus|App::cpanminus>. The method explicitly does not
1555 attempt to validate the state of required environment variables (if any).
1557 For instance if some of the requirements for C<deploy> are not available,
1558 the returned string could look like:
1561 push @chunks, qq{ "SQL::Translator~$sqltver"};
1563 push @chunks, <<'EOC';
1565 See also L</-list_missing>.
1571 =item Arguments: $group_name | \@group_names
1575 A convenience wrapper around L<skip|Test::More/SKIP>. It does not take neither
1576 a reason (it is generated by L</req_missing_for>) nor an amount of skipped tests
1577 (it is always C<1>, thus mandating unconditional use of
1578 L<done_testing|Test::More/done_testing>). Most useful in combination with ad hoc
1579 requirement specifications:
1582 push @chunks, <<EOC;
1584 $class->skip_without([ deploy YAML>=0.90 ]);
1590 push @chunks, <<'EOC';
1592 =head2 die_unless_req_ok_for
1596 =item Arguments: $group_name | \@group_names
1600 Checks if L</req_ok_for> passes for the supplied group(s), and
1601 in case of failure throws an exception including the information
1602 from L</req_missing_for>. See also L</-die_without>.
1604 =head2 modreq_errorlist_for
1608 =item Arguments: $group_name | \@group_names
1610 =item Return Value: \%set_of_loaderrors_per_module
1614 Returns a hashref containing the actual errors that occurred while attempting
1615 to load each module in the requirement group(s).
1617 =head2 req_errorlist_for
1619 Deprecated method name, equivalent (via proxy) to L</modreq_errorlist_for>.
