251 | =head1 NAME |
252 | |
253 | ExtUtils::Manifest - utilities to write and check a MANIFEST file |
254 | |

257 | C<require ExtUtils::Manifest;> |
258 | |
259 | C<ExtUtils::Manifest::mkmanifest;> |
260 | |
261 | C<ExtUtils::Manifest::manicheck;> |

263 | C<ExtUtils::Manifest::filecheck;> |
264 | |
265 | C<ExtUtils::Manifest::fullcheck;> |
266 | |
267 | C<ExtUtils::Manifest::skipcheck;> |
268 | |
269 | C<ExtUtild::Manifest::manifind();> |
270 | |
271 | C<ExtUtils::Manifest::maniread($file);> |
272 | |
273 | C<ExtUtils::Manifest::manicopy($read,$target,$how);> |
274 | |
275 | =head1 DESCRIPTION |
276 | |
277 | Mkmanifest() writes all files in and below the current directory to a |
278 | file named in the global variable $ExtUtils::Manifest::MANIFEST (which |
279 | defaults to C<MANIFEST>) in the current directory. It works similar to |
280 | |
281 | find . -print |
282 | |
283 | but in doing so checks each line in an existing C<MANIFEST> file and |
284 | includes any comments that are found in the existing C<MANIFEST> file |
285 | in the new one. Anything between white space and an end of line within |
286 | a C<MANIFEST> file is considered to be a comment. Filenames and |
287 | comments are seperated by one or more TAB characters in the |
288 | output. All files that match any regular expression in a file |
289 | C<MANIFEST.SKIP> (if such a file exists) are ignored. |
290 | |
f1387719 |
291 | Manicheck() checks if all the files within a C<MANIFEST> in the |
292 | current directory really do exist. It only reports discrepancies and |
293 | exits silently if MANIFEST and the tree below the current directory |
294 | are in sync. |
79dd614e |
295 | |
296 | Filecheck() finds files below the current directory that are not |
297 | mentioned in the C<MANIFEST> file. An optional file C<MANIFEST.SKIP> |
298 | will be consulted. Any file matching a regular expression in such a |
299 | file will not be reported as missing in the C<MANIFEST> file. |
300 | |
301 | Fullcheck() does both a manicheck() and a filecheck(). |
302 | |
303 | Skipcheck() lists all the files that are skipped due to your |
304 | C<MANIFEST.SKIP> file. |
305 | |
306 | Manifind() retruns a hash reference. The keys of the hash are the |
307 | files found below the current directory. |
308 | |
309 | Maniread($file) reads a named C<MANIFEST> file (defaults to |
310 | C<MANIFEST> in the current directory) and returns a HASH reference |
311 | with files being the keys and comments being the values of the HASH. |
312 | |
313 | I<Manicopy($read,$target,$how)> copies the files that are the keys in |
314 | the HASH I<%$read> to the named target directory. The HASH reference |
315 | I<$read> is typically returned by the maniread() function. This |
316 | function is useful for producing a directory tree identical to the |
317 | intended distribution tree. The third parameter $how can be used to |
318 | specify a different methods of "copying". Valid values are C<cp>, |
319 | which actually copies the files, C<ln> which creates hard links, and |
320 | C<best> which mostly links the files but copies any symbolic link to |
321 | make a tree without any symbolic link. Best is the default. |
322 | |
323 | =head1 MANIFEST.SKIP |
324 | |
325 | The file MANIFEST.SKIP may contain regular expressions of files that |
326 | should be ignored by mkmanifest() and filecheck(). The regular |
327 | expressions should appear one on each line. A typical example: |
328 | |
329 | \bRCS\b |
330 | ^MANIFEST\. |
331 | ^Makefile$ |
332 | ~$ |
333 | \.html$ |
334 | \.old$ |
335 | ^blib/ |
336 | ^MakeMaker-\d |
337 | |
338 | =head1 EXPORT_OK |
339 | |
340 | C<&mkmanifest>, C<&manicheck>, C<&filecheck>, C<&fullcheck>, |
341 | C<&maniread>, and C<&manicopy> are exportable. |
342 | |
343 | =head1 GLOBAL VARIABLES |
344 | |
345 | C<$ExtUtils::Manifest::MANIFEST> defaults to C<MANIFEST>. Changing it |
346 | results in both a different C<MANIFEST> and a different |
347 | C<MANIFEST.SKIP> file. This is useful if you want to maintain |
348 | different distributions for different audiences (say a user version |
349 | and a developer version including RCS). |
350 | |
81ff29e3 |
351 | C<$ExtUtils::Manifest::Quiet> defaults to 0. If set to a true value, |
79dd614e |
352 | all functions act silently. |
353 | |
354 | =head1 DIAGNOSTICS |
355 | |
356 | All diagnostic output is sent to C<STDERR>. |
357 | |
358 | =over |
359 | |
360 | =item C<Not in MANIFEST:> I<file> |
361 | |
362 | is reported if a file is found, that is missing in the C<MANIFEST> |
363 | file which is excluded by a regular expression in the file |
364 | C<MANIFEST.SKIP>. |
365 | |
366 | =item C<No such file:> I<file> |
367 | |
368 | is reported if a file mentioned in a C<MANIFEST> file does not |
369 | exist. |
370 | |
371 | =item C<MANIFEST:> I<$!> |
372 | |
373 | is reported if C<MANIFEST> could not be opened. |
374 | |
375 | =item C<Added to MANIFEST:> I<file> |
376 | |
377 | is reported by mkmanifest() if $Verbose is set and a file is added |
378 | to MANIFEST. $Verbose is set to 1 by default. |
