338 | |
339 | =head1 DESCRIPTION |
340 | |
341 | L<ExtUtils::MakeMaker> works well enough as development tool for |
342 | builting and testing, but using it to release is annoying and error prone. |
343 | Distar adds just enough to L<ExtUtils::MakeMaker> for it to be a usable dist |
344 | author tool. This includes extra commands for releasing and safety checks, and |
345 | automatic generation of some files. It doesn't require any non-core modules and |
346 | is compatible with old versions of perl. |
347 | |
348 | =head1 FUNCTIONS |
349 | |
350 | =head2 author( $author ) |
351 | |
352 | Set the author to include in generated META files. Can be a single entry, or |
353 | an arrayref. |
354 | |
355 | =head2 manifest_include( $dir, $pattern ) |
356 | |
357 | Add a pattern to include files in the MANIFEST file, and thus in the generated |
358 | dist files. |
359 | |
360 | The pattern can be either a regex, or a path suffix. It will be applied to the |
361 | full path past the directory specified. |
362 | |
363 | The default files that are always included are: F<.pm> and F<.pod> files in |
364 | F<lib>, F<.t> files in F<t> and F<xt>, F<.pm> files in F<t/lib> and F<xt/lib>, |
365 | F<Changes>, F<MANIFEST>, F<README>, F<LICENSE>, F<META.yml>, and F<.PL> files in |
366 | the dist root, and all files in F<maint>. |
367 | |
368 | =head1 AUTOGENERATED FILES |
369 | |
370 | =over 4 |
371 | |
372 | =item F<MANIFEST.SKIP> |
373 | |
374 | The F<MANIFEST.SKIP> will be automatically generated to exclude any files not |
375 | explicitly allowed via C<manifest_include> or the included defaults. It will be |
376 | created (or updated) at C<perl Makefile.PL> time. |
377 | |
378 | =item F<README> |
379 | |
380 | The F<README> file will be generated at dist generation time, inside the built |
381 | dist. It will be generated using C<pod2text> on the main module. |
382 | |
383 | If a F<README> file exists in the repo, it will be used directly instead of |
384 | generating the file. |
385 | |
386 | =back |
387 | |
388 | =head1 MAKE COMMMANDS |
389 | |
390 | =head2 test |
391 | |
392 | test will be adjusted to include F<xt/> tests by default. This will only apply |
393 | for authors, not users installing from CPAN. |
394 | |
395 | =head2 release |
396 | |
397 | Releases the dist. Before releasing, checks will be done on the dist using the |
398 | C<preflight> and C<releasetest> commands. |
399 | |
400 | Releasing will generate a dist tarball and upload it to CPAN using cpan-upload. |
401 | It will also create a git tag for the release, and push the tag and branch. |
402 | |
83e12da3 |
403 | =head3 FAKE_RELEASE |
263b723e |
404 | |
405 | If release is run with FAKE_RELEASE=1 set, it will skip uploading to CPAN and |
406 | pushing to git. A release commit will still be created and tagged locally. |
407 | |
edb4539a |
408 | =head2 preflight |
409 | |
410 | Performs a number of checks on the files and repository, ensuring it is in a |
411 | sane state to do a release. The checks are: |
412 | |
413 | =over 4 |
414 | |
415 | =item * All version numbers match |
416 | |
417 | =item * The F<MANIFEST> file is up to date |
418 | |
419 | =item * The branch is correct |
420 | |
421 | =item * There is no existing tag for the version |
422 | |

448 | with underscores will preserve the underscore in the same position. |
