stats about cpan modules shipped by mandriva

adam and gabor asked me about some information on what cpan modules are shipped as rpm packages by mandriva... i finally found some time to work on it and produced ordb::cpan::mandriva.

this module is basically a sqlite database replicated automatically by orlite::mirror. using it is very simple - for example, couting the cpan dists shipped by mandriva is achieved by the following snippet:

(fyi, the result is 1899 as of writing, +1 since i just imported the module itself)

at module use time, it will automatically download (and cache for a week) the sqlite database. and one can then use the module as an ordb for this db... the module does not however produces the stats for you - so alias & gabor, now is your turn to work! :-) i'm waiting for your top-100 most wanted mandriva or whatever crazy stats you'll want to produce.

the database itself is generated by module::packaged::generator. this module uses different drivers depending on the current linux distribution (but nothing prevents *bsd to also have a driver) it runs on. only mandriva is supported currently, but ryan will work on a debian driver. all other contributions are most welcome - the code is on github: fork it and send me pull requests!

next padre version will (finally) recognize dist-zilla projects

padre 0.55, due tomorrow, will finally recognize dist-zilla projects correctly. among other things, it means that it will set @INC accordingly for syntax checking, keep the directory browser at the project root, etc.

it took a bit of time since the "installer" detection is spread out in different places in padre... this needs refactoring, for those interested.

some dzil goodness coming

i scratched some itches in dist-zilla, and hopefully the result will be useful to you too... some are rather trivial, while some are more feature-ful.

on the it-s-the-details-that-count front, dzil clean will now remove *~ files lingering in your local copy.

dzil command now accepts a -I argument that adds a directory to perl @INC (same as perl's -I option). which means dzil plugin author can now do:

$ dzil -Ilib release

and release their distribution using the latest version of their plugin...

a new run subcommand has been added, which is doing more or less the following:

$ dzil build
$ rsync -avp My-Project-version/ .build/
$ cd .build
$ perl Makefile.PL     # or perl Build.PL
$ make                 # or ./Build     
$ export PERL5LIB=$PWD/blib/lib:$PWD/blib/arch
$ launch command defined by rest of your args

which means you can now do:

$ dzil run ./bin/myscript
$ dzil run prove -l t/unit.t
$ dzil run bash

the first one is specially useful if you're using file::sharedir and don't want to add extra hooks detecting whether it runs in a dev checkout or not.

speaking of sharedir, i crafted a quick'n'dirty implementation that made modulebuild plugin automatically install an existing share directory (which is possible since module::build 0.36). rjbs then re-factored it to use the installdirs plugin. nperez then finalized the work for the makemaker plugin. so if you have a share directory, it will now be automatically recognized as such by dzil and installed accordingly.

rjbs just released a new version of dist-zilla with those enhancements (and other stuff).

cpan task for dist-zilla

dist-zilla has a lot of prereqs. and even when you have installed it, you may need to install other plugins manually. therefore, i just uploaded task::dist::zilla that pulls in all dzil plugins and plugin bundles.

it still takes time to install all those modules, but at least you can do it in one go with cpan or cpanplus: no need to install them one by one manually.

of course, if you're on mandriva, running:

urpmi perl-Dist-Zilla

will install the package perl-Dist-Zilla and all its deps while also suggesting to install all the dzil plugins...

retrospective 2009

2009's over, but the year was quite a busy one for me on the perl front:

• i finally took the time to investigate moose, and decided to port some of my code to use it.
• i discovered dist::zilla, and definitely plan to use it in all my dists.
• i discovered some other cool new perl modules (thanks guys).
  
• i uploaded some new dists on cpan, including games::pandemic (which i'm quite proud of, even if i need to continue hacking on it).
• i updated & released some of my existing dists.
  
• i contributed to other projects such as padre, dist-zilla, etc. sending patches is a good way to thank the author for their work.
• it's even easier to contribute with github, which i'm using more and more for my projects (and it's no more slow by now, woohoo!). of course, git is the master piece allowing this easy sharing.
  
• on mandriva's front, i resurrected parrot rpm, and finally shipped rakudo.
  
• 2009 was also the year of the great migration to %perl_convert_version
• ... with lots of new perl modules available as rpm (i am managing 450 of them).
  
• ... and finally i took ownership of perl rpm. (thank you perl5 porters btw for 5.10.1 and the push for next stable version!)

so, busy indeed 2009 was... i just hope that 2010 will be as fruitful on the perl front for me, and for the perl ecosystem by large.
