243 | =head1 NAME | |
244 | ||
245 | ExtUtils::Installed - Inventory management of installed modules | |
246 | ||
247 | =head1 SYNOPSIS | |
248 | ||
249 | use ExtUtils::Installed; | |
250 | my ($inst) = ExtUtils::Installed->new(); | |
251 | my (@modules) = $inst->modules(); | |
252 | my (@missing) = $inst->validate("DBI"); | |
253 | my $all_files = $inst->files("DBI"); | |
254 | my $files_below_usr_local = $inst->files("DBI", "all", "/usr/local"); | |
255 | my $all_dirs = $inst->directories("DBI"); | |
256 | my $dirs_below_usr_local = $inst->directory_tree("DBI", "prog"); | |
257 | my $packlist = $inst->packlist("DBI"); | |
258 | ||
259 | =head1 DESCRIPTION | |
260 | ||
261 | ExtUtils::Installed provides a standard way to find out what core and module | |
262 | files have been installed. It uses the information stored in .packlist files | |
263 | created during installation to provide this information. In addition it | |
264 | provides facilities to classify the installed files and to extract directory | |
265 | information from the .packlist files. | |
266 | ||
267 | =head1 USAGE | |
268 | ||
269 | The new() function searches for all the installed .packlists on the system, and | |
270 | stores their contents. The .packlists can be queried with the functions | |
271 | described below. | |
272 | ||
273 | =head1 FUNCTIONS | |
274 | ||
bbc7dcd2 | 275 | =over 4 |
354f3b56 AB |
276 | |
277 | =item new() | |
278 | ||
279 | This takes no parameters, and searches for all the installed .packlists on the | |
280 | system. The packlists are read using the ExtUtils::packlist module. | |
281 | ||
282 | =item modules() | |
283 | ||
284 | This returns a list of the names of all the installed modules. The perl 'core' | |
285 | is given the special name 'Perl'. | |
286 | ||
287 | =item files() | |
288 | ||
289 | This takes one mandatory parameter, the name of a module. It returns a list of | |
290 | all the filenames from the package. To obtain a list of core perl files, use | |
291 | the module name 'Perl'. Additional parameters are allowed. The first is one | |
34dcf69d | 292 | of the strings "prog", "doc" or "all", to select either just program files, |
354f3b56 AB |
293 | just manual files or all files. The remaining parameters are a list of |
294 | directories. The filenames returned will be restricted to those under the | |
295 | specified directories. | |
296 | ||
297 | =item directories() | |
298 | ||
299 | This takes one mandatory parameter, the name of a module. It returns a list of | |
300 | all the directories from the package. Additional parameters are allowed. The | |
34dcf69d | 301 | first is one of the strings "prog", "doc" or "all", to select either just |
354f3b56 AB |
302 | program directories, just manual directories or all directories. The remaining |
303 | parameters are a list of directories. The directories returned will be | |
304 | restricted to those under the specified directories. This method returns only | |
305 | the leaf directories that contain files from the specified module. | |
306 | ||
307 | =item directory_tree() | |
308 | ||
34dcf69d | 309 | This is identical in operation to directories(), except that it includes all the |
354f3b56 AB |
310 | intermediate directories back up to the specified directories. |
311 | ||
312 | =item validate() | |
313 | ||
314 | This takes one mandatory parameter, the name of a module. It checks that all | |
315 | the files listed in the modules .packlist actually exist, and returns a list of | |
316 | any missing files. If an optional second argument which evaluates to true is | |
317 | given any missing files will be removed from the .packlist | |
318 | ||
319 | =item packlist() | |
320 | ||
321 | This returns the ExtUtils::Packlist object for the specified module. | |
322 | ||
323 | =item version() | |
324 | ||
325 | This returns the version number for the specified module. | |
