57 | =head1 DESCRIPTION |
58 | |
59 | This module provides the programmer's interface to the C<CPANPLUS> |
60 | libraries. |
61 | |
62 | =head1 ENVIRONMENT |
63 | |
64 | When C<CPANPLUS::Backend> is loaded, which is necessary for just |
65 | about every <CPANPLUS> operation, the environment variable |
66 | C<PERL5_CPANPLUS_IS_RUNNING> is set to the current process id. |
67 | |
68 | Additionally, the environment variable C<PERL5_CPANPLUS_IS_VERSION> |
69 | will be set to the version of C<CPANPLUS::Backend>. |
70 | |
71 | This information might be useful somehow to spawned processes. |
72 | |
73 | =head1 METHODS |
74 | |
75 | =head2 $cb = CPANPLUS::Backend->new( [CONFIGURE_OBJ] ) |
76 | |
77 | This method returns a new C<CPANPLUS::Backend> object. |
78 | This also initialises the config corresponding to this object. |
79 | You have two choices in this: |
80 | |
81 | =over 4 |
82 | |
83 | =item Provide a valid C<CPANPLUS::Configure> object |
84 | |
85 | This will be used verbatim. |
86 | |
87 | =item No arguments |
88 | |
89 | Your default config will be loaded and used. |
90 | |
91 | =back |
92 | |
93 | New will return a C<CPANPLUS::Backend> object on success and die on |
94 | failure. |

120 | and C<module_tree> will try to look up these module names and |
121 | return the corresponding module objects instead. |

136 | ### From John Malmberg: This is failing on VMS |
137 | ### because ODS-2 does not retain the case of |
138 | ### filenames that are created. |

140 | ### to a module name and then looked up in the |
141 | ### %$modtree hash. |
142 | ### |
143 | ### As a fix, we do a search on VMS instead -- |
144 | ### more cpu cycles, but it gets around the case |

220 | |
221 | C<search> enables you to search for either module or author objects, |
222 | based on their data. The C<type> you can specify is any of the |
223 | accessors specified in C<CPANPLUS::Module::Author> or |
224 | C<CPANPLUS::Module>. C<search> will determine by the C<type> you |
225 | specified whether to search by author object or module object. |
226 | |
227 | You have to specify an array reference of regular expressions or |
228 | strings to match against. The rules used for this array ref are the |
229 | same as in C<Params::Check>, so read that manpage for details. |
230 | |
231 | The search is an C<or> search, meaning that if C<any> of the criteria |
232 | match, the search is considered to be successful. |
233 | |
234 | You can specify the result of a previous search as C<data> to limit |
235 | the new search to these module or author objects, rather than the |
236 | entire module or author tree. This is how you do C<and> searches. |
237 | |
238 | Returns a list of module or author objects on success and false |
239 | on failure. |

437 | If C<parse_module> is unable to actually find the module you are looking |

441 | real thing. |
442 | |
443 | See L<CPANPLUS::Module> for the operations you can perform on a |
444 | module object. |
445 | |

754 | |
755 | =item * C<lib> |
756 | |
757 | This resets PERL5LIB, which is changed to ensure that while installing |
758 | modules they are in our @INC. |
759 | |
760 | =item * C<load> |
761 | |
762 | This resets the cache of modules we've attempted to load, but failed. |

764 | somehow have become available. |

824 | in your C<CPANPLUS::Config> you can use your local mirror to install |

1067 | Besides the sources as provided by the general C<CPAN> mirrors, it's |
1068 | possible to add your own sources list to your C<CPANPLUS> index. |
1069 | |
1070 | The methodology behind this works much like C<Debian's apt-sources>. |
1071 | |
1072 | The methods below show you how to make use of this functionality. Also |
1073 | note that most of these methods are available through the default shell |
1074 | plugin command C</cs>, making them available as shortcuts through the |
1075 | shell and via the commandline. |

1080 | as follows: |
1081 | |
1082 | /full/path/to/local/index => http://remote/source |

1094 | Adds an C<URI> to your own sources list and mirrors its index. See the |
1095 | documentation on C<< $cb->update_custom_source >> on how this is done. |

1098 | |
1099 | Note that when adding a new C<URI>, the change to the in-memory tree is |
1100 | not saved until you rebuild or save the tree to disk again. You can do |
1101 | this using the C<< $cb->reload_indices >> method. |

1111 | Removes an C<URI> from your own sources list and removes its index. |
1112 | |
1113 | To find out what C<URI>s you have as part of your own sources list, use |
1114 | the C<< $cb->list_custom_sources >> method. |

1125 | |
1126 | =head2 $bool = $cb->update_custom_source( [remote => URI] ); |
1127 | |
1128 | Updates the indexes for all your custom sources. It does this by fetching |
1129 | a file called C<packages.txt> in the root of the custom sources's C<URI>. |
1130 | If you provide the C<remote> argument, it will only update the index for |
1131 | that specific C<URI>. |
1132 | |
1133 | Here's an example of how custom sources would resolve into index files: |
1134 | |
1135 | file:///path/to/sources => file:///path/to/sources/packages.txt |
1136 | http://example.com/sources => http://example.com/sources/packages.txt |
1137 | ftp://example.com/sources => ftp://example.com/sources/packages.txt |
1138 | |
1139 | The file C<packages.txt> simply holds a list of packages that can be found |
1140 | under the root of the C<URI>. This file can be automatically generated for |
1141 | you when the remote source is a C<file:// URI>. For C<http://>, C<ftp://>, |
1142 | and similar, the administrator of that repository should run the method |
1143 | C<< $cb->write_custom_source_index >> on the repository to allow remote |
1144 | users to index it. |
1145 | |
1146 | For details, see the C<< $cb->write_custom_source_index >> method below. |
1147 | |
1148 | All packages that are added via this mechanism will be attributed to the |
1149 | author with C<CPANID> C<LOCAL>. You can use this id to search for all |
1150 | added packages. |

1167 | |
1168 | Writes the index for a custom repository root. Most users will not have to |
1169 | worry about this, but administrators of a repository will need to make sure |
1170 | their indexes are up to date. |
1171 | |
1172 | The index will be written to a file called C<packages.txt> in your repository |
1173 | root, which you can specify with the C<path> argument. You can override this |
1174 | location by specifying the C<to> argument, but in normal operation, that should |
1175 | not be required. |
1176 | |
1177 | Once the index file is written, users can then add the C<URI> pointing to |
1178 | the repository to their custom list of sources and start using it right away. See the C<< $cb->add_custom_source >> method for user details. |
