326 ExtUtils::Manifest - utilities to write and check a MANIFEST file
330 require ExtUtils::Manifest;
332 ExtUtils::Manifest::mkmanifest;
334 ExtUtils::Manifest::manicheck;
336 ExtUtils::Manifest::filecheck;
338 ExtUtils::Manifest::fullcheck;
340 ExtUtils::Manifest::skipcheck;
342 ExtUtils::Manifest::manifind();
344 ExtUtils::Manifest::maniread($file);
346 ExtUtils::Manifest::manicopy($read,$target,$how);
350 mkmanifest() writes all files in and below the current directory to a
351 file named in the global variable $ExtUtils::Manifest::MANIFEST (which
352 defaults to C<MANIFEST>) in the current directory. It works similar to
356 but in doing so checks each line in an existing C<MANIFEST> file and
357 includes any comments that are found in the existing C<MANIFEST> file
358 in the new one. Anything between white space and an end of line within
359 a C<MANIFEST> file is considered to be a comment. Filenames and
360 comments are separated by one or more TAB characters in the
361 output. All files that match any regular expression in a file
362 C<MANIFEST.SKIP> (if such a file exists) are ignored.
364 manicheck() checks if all the files within a C<MANIFEST> in the
365 current directory really do exist. It only reports discrepancies and
366 exits silently if MANIFEST and the tree below the current directory
369 filecheck() finds files below the current directory that are not
370 mentioned in the C<MANIFEST> file. An optional file C<MANIFEST.SKIP>
371 will be consulted. Any file matching a regular expression in such a
372 file will not be reported as missing in the C<MANIFEST> file.
374 fullcheck() does both a manicheck() and a filecheck().
376 skipcheck() lists all the files that are skipped due to your
377 C<MANIFEST.SKIP> file.
379 manifind() returns a hash reference. The keys of the hash are the
380 files found below the current directory.
382 maniread($file) reads a named C<MANIFEST> file (defaults to
383 C<MANIFEST> in the current directory) and returns a HASH reference
384 with files being the keys and comments being the values of the HASH.
385 Blank lines and lines which start with C<#> in the C<MANIFEST> file
388 C<manicopy($read,$target,$how)> copies the files that are the keys in
389 the HASH I<%$read> to the named target directory. The HASH reference
390 $read is typically returned by the maniread() function. This
391 function is useful for producing a directory tree identical to the
392 intended distribution tree. The third parameter $how can be used to
393 specify a different methods of "copying". Valid values are C<cp>,
394 which actually copies the files, C<ln> which creates hard links, and
395 C<best> which mostly links the files but copies any symbolic link to
396 make a tree without any symbolic link. Best is the default.
400 The file MANIFEST.SKIP may contain regular expressions of files that
401 should be ignored by mkmanifest() and filecheck(). The regular
402 expressions should appear one on each line. Blank lines and lines
403 which start with C<#> are skipped. Use C<\#> if you need a regular
404 expression to start with a sharp character. A typical example:
406 # Version control files and dirs.
411 # Makemaker generated files and dirs.
417 # Temp, old and emacs backup files.
423 If no MANIFEST.SKIP file is found, a default set of skips will be
424 used, similar to the example above. If you want nothing skipped,
425 simply make an empty MANIFEST.SKIP file.
430 C<&mkmanifest>, C<&manicheck>, C<&filecheck>, C<&fullcheck>,
431 C<&maniread>, and C<&manicopy> are exportable.
433 =head1 GLOBAL VARIABLES
435 C<$ExtUtils::Manifest::MANIFEST> defaults to C<MANIFEST>. Changing it
436 results in both a different C<MANIFEST> and a different
437 C<MANIFEST.SKIP> file. This is useful if you want to maintain
438 different distributions for different audiences (say a user version
439 and a developer version including RCS).
441 C<$ExtUtils::Manifest::Quiet> defaults to 0. If set to a true value,
442 all functions act silently.
444 C<$ExtUtils::Manifest::Debug> defaults to 0. If set to a true value,
445 or if PERL_MM_MANIFEST_DEBUG is true, debugging output will be
450 All diagnostic output is sent to C<STDERR>.
454 =item C<Not in MANIFEST:> I<file>
456 is reported if a file is found, that is missing in the C<MANIFEST>
457 file which is excluded by a regular expression in the file
460 =item C<No such file:> I<file>
462 is reported if a file mentioned in a C<MANIFEST> file does not
465 =item C<MANIFEST:> I<$!>
467 is reported if C<MANIFEST> could not be opened.
469 =item C<Added to MANIFEST:> I<file>
471 is reported by mkmanifest() if $Verbose is set and a file is added
472 to MANIFEST. $Verbose is set to 1 by default.
480 =item B<PERL_MM_MANIFEST_DEBUG>
488 L<ExtUtils::MakeMaker> which has handy targets for most of the functionality.
