5. = Making a CPAN distribution Tuesday, November 15, 2011

6. Declaring CPAN Dependencies Tuesday, November 15, 2011

7. Makefile.PL Build.PL Tuesday, November 15, 2011

8. use  ExtUtils::MakeMaker; WriteMakefile(    NAME  =>  ‘MyModule’,    VERSION  =>

    ‘1.22’,    PREREQ_PM  =>  {        ‘JSON’  =>  0,        ‘Hash::MultiValue’  =>  ‘0.11’,    }, ); Tuesday, November 15, 2011

9. use  Module::Build; my  $build  =  Module::Build-­‐>new(    module_name  =>  ‘MyModule’,

      requires  =>  {        ‘JSON’  =>  ‘2.00’,        ‘Hash::MultiValie’  =>  ‘0.20’,    }, ); $build-­‐>create_build_script; Tuesday, November 15, 2011

10. use  inc::Module::Install; name  ‘MyApp’; all_from  ‘lib/MyApp.pm’; requires  ‘JSON’,  ‘2.00’; requires

     ‘Hash::MultiValue’  =>  0.10; WriteAll; Tuesday, November 15, 2011

11. Or use Dist::Zilla. Tuesday, November 15, 2011

12. Making a Perl application that depends on CPAN modules Tuesday,

13. ≠ Making a CPAN distribution Tuesday, November 15, 2011

14. Declaring CPAN Dependencies Tuesday, November 15, 2011

15. ? Tuesday, November 15, 2011

16. Makefile.PL Build.PL Tuesday, November 15, 2011

17. Problems with Makefile.PL/Build.PL Tuesday, November 15, 2011

18. Lots of boilerplate Tuesday, November 15, 2011

19. use  ExtUtils::MakeMaker; WriteMakefile(    NAME  =>  ‘MyModule’,    VERSION  =>

     ‘1.22’,    PREREQ_PM  =>  {        ‘JSON’  =>  0,        ‘Hash::MultiValue’  =>  ‘0.11’,    }, ); Tuesday, November 15, 2011

20. use  Module::Build; my  $build  =  Module::Build-­‐>new(    module_name  =>  ‘MyModule’,

       requires  =>  {        ‘JSON’  =>  ‘2.00’,        ‘Hash::MultiValie’  =>  ‘0.20’,    }, ); $build-­‐>create_build_script; Tuesday, November 15, 2011

21. use  inc::Module::Install; name  ‘MyApp’; all_from  ‘lib/MyApp.pm’; requires  ‘JSON’,  ‘2.00’; requires

     ‘Hash::MultiValue’  =>  0.10; WriteAll; Tuesday, November 15, 2011

22. dzil has no boilerplate ... but it’s not a distribution!

    Tuesday, November 15, 2011

23. Can have deps configure_requires, META.yml inc/Module/Install.pm Tuesday, November 15, 2011

24. Makefile.PL Build.PL Tuesday, November 15, 2011

25. configure build test install Tuesday, November 15, 2011

26. configure build test install ✔ Tuesday, November 15, 2011

27. My application is not meant to be installed! e.g. dotcloud

    push Tuesday, November 15, 2011

28. Great for dists. Not-so for apps. Tuesday, November 15, 2011

29. By the way... Tuesday, November 15, 2011

30. I <3 Module::Install’s DSL Tuesday, November 15, 2011

31. CPAN Meta Spec v2 Awesome stuff. Tuesday, November 15, 2011

32. Tuesday, November 15, 2011

33. Marrying them together? Tuesday, November 15, 2011

34. A Proposal Tuesday, November 15, 2011

35. cpanfile Tuesday, November 15, 2011

36. requires  ‘Plack’,  0.9980; requires  ‘Catalyst’,  ‘>=  5.8,  <  5.9’; conflicts

     ‘MooseX::Foo’,  ‘<  0.10’; on  ‘test’  =>  sub  {        requires  ‘Test::More’,  0.80; }; on  ‘develop’  =>  sub  {        requires  ‘Devel::NYTProf’; }; Tuesday, November 15, 2011

37. inspired by: gemfile(5) Tuesday, November 15, 2011

38. Backward compatible to: Module::Install(::DSL) Tuesday, November 15, 2011

39. Convertible to: CPAN::Meta::Prereqs Tuesday, November 15, 2011

40. requires  ‘Plack’,  0.9980; requires  ‘Catalyst’,  ‘>=  5.8,  <  5.9’; conflicts

     ‘MooseX::Foo’,  ‘<  0.10’; on  ‘test’  =>  sub  {        requires  ‘Test::More’,  0.80; }; on  ‘develop’  =>  sub  {        requires  ‘Devel::NYTProf’; }; Tuesday, November 15, 2011

41. CPAN::Meta::Prereqs-­‐>new({    runtime  =>  {        requires  =>

     {            ‘Plack’  =>  0.9980,            ‘Catalyst’  =>  ‘>=  5.8,  <  5.9’,        },        conflicts  =>  {            ‘MooseX::Foo’  =>  ‘<  0.10’,        },    },    test  =>  {        requires  =>  {            ‘Test::More’  =>  0.80,        },    },    develop  =>  {        requires  =>  {            ‘Devel::NYTProf’  =>  0,        },    } }); Tuesday, November 15, 2011

42. Will be supported by: cpanm 1.6, carton 1.0 Tuesday, November
