1040 | B<Note>: The C<eval> protection within the example is due to support for |
1041 | requirements during L<the C<configure> build phase|CPAN::Meta::Spec/Phases> |
1042 | not being available on a sufficient portion of production installations of |
1043 | Perl. Robust support for such dependency requirements is available in the |
1044 | L<CPAN> installer only since version C<1.94_56> first made available for |
1045 | production with perl version C<5.12>. It is the belief of the current |
1046 | maintainer that support for requirements during the C<configure> build phase |
1047 | will not be sufficiently ubiquitous until the B<year 2020> at the earliest, |
1048 | hence the extra care demonstrated above. It should also be noted that some |
1049 | 3rd party installers (e.g. L<cpanminus|App::cpanminus>) do the right thing |
1050 | with configure requirements independent from the versions of perl and CPAN |
1051 | available. |

1059 | =head1 DESCRIPTION |
1060 | |
1061 | Some of the less-frequently used features of L<DBIx::Class::Schema::Loader> have external |
ef8e9c69 |
1062 | module dependencies on their own. In order not to burden the average user |
406a97c2 |
1063 | with modules they will never use, these optional dependencies are not included |
ef8e9c69 |
1064 | in the base Makefile.PL. Instead an exception with a descriptive message is |
406a97c2 |
1065 | thrown when a specific feature can't find one or several modules required for |
1066 | its operation. This module is the central holding place for the current list |
1067 | of such dependencies, for DBIx::Class::Schema::Loader core authors, and DBIx::Class::Schema::Loader extension |
1068 | authors alike. |
1069 | |
1070 | Dependencies are organized in L<groups|/CURRENT REQUIREMENT GROUPS> where each |
1071 | group can list one or more required modules, with an optional minimum version |
1072 | (or 0 for any version). In addition groups prefixed with C<test_> can specify |
1073 | a set of environment variables, some (or all) of which are marked as required |
1074 | for the group to be considered by L</req_list_for> |
1075 | |
1076 | Each group name (or a combination thereof) can be used in the |
1077 | L<public methods|/METHODS> as described below. |

1228 | dependencies B<keyed> by dependency group. Each key (group name), or a combination |
1229 | thereof (as an arrayref) can be supplied to the methods below. |
1230 | The B<values> of the returned hash are currently a set of options B<without a |
1231 | well defined structure>. If you have use for any of the contents - contact the |
1232 | maintainers, instead of treating this as public (left alone stable) API. |

1246 | DBIx::Class::Schema::Loader (regardless of their availability on the system). |
1247 | See the L</SYNOPSIS> for a real-world example. |
1248 | |
1249 | When handling C<test_*> groups this method behaves B<differently> from |
1250 | L</modreq_list_for> below (and is the only such inconsistency among the |
1251 | C<req_*> methods). If a particular group declares as requirements some |
1252 | C<environment variables> and these requirements are not satisfied (the envvars |
1253 | are unset) - then the C<module requirements> of this group are not included in |
1254 | the returned list. |

1291 | =back |
1292 | |
1293 | Returns a single-line string suitable for inclusion in larger error messages. |
1294 | This method would normally be used by DBIx::Class::Schema::Loader core features, to indicate to |
1295 | the user that they need to install specific modules and/or set specific |
1296 | environment variables before being able to use a specific feature set. |
1297 | |
1298 | For example if some of the requirements for C<deploy> are not available, |
ef8e9c69 |
1299 | the returned string could look like: |
406a97c2 |

406a97c2 |
1302 | push @chunks, qq{ "Moose~$moosever" (see $class documentation for details)}; |

1303 | |
406a97c2 |
1304 | push @chunks, <<'EOC'; |
ef8e9c69 |
1305 | The author is expected to prepend the necessary text to this message before |
406a97c2 |
1306 | returning the actual error seen by the user. See also L</modreq_missing_for> |

1318 | Same as L</req_missing_for> except that the error string is guaranteed to be |
1319 | either empty, or contain a set of module requirement specifications suitable |
1320 | for piping to e.g. L<cpanminus|App::cpanminus>. The method explicitly does not |
1321 | attempt to validate the state of required environment variables (if any). |
1322 | |
1323 | For instance if some of the requirements for C<deploy> are not available, |
1324 | the returned string could look like: |
1325 | EOC |
1326 | |
1327 | push @chunks, qq{ "Moose~$moosever"}; |

1343 | (it is always C<1>, thus mandating unconditional use of |
1344 | L<done_testing|Test::More/done_testing>). Most useful in combination with ad hoc |
