NAME

Test::HasVersion - Check Perl modules have version numbers

CONTENTS

SYNOPSIS

Test::HasVersion lets you check a Perl module has a version number in a Test::Simple fashion.



  use Test::HasVersion tests => 1;
  pm_version_ok("M.pm", "Valid version");



Module authors can include the following in a t/has_version.t file and let Test::HasVersion find and check all installable PM files in a distribution.



  use Test::More;
  eval "use Test::HasVersion";
  plan skip_all =>
       Test::HasVersion required for testing for version numbers if $@;
  all_pm_version_ok();



DESCRIPTION

Do you wanna check that every one of your Perl modules in a distribution has a version number? You wanna make sure you don’t forget the brand new modules you just added? Well, that’s the module you have been looking for. Use it!

Do you wanna check someone else’s distribution to make sure the author have not committed the sin of leaving Perl modules without a version that can be used to tell if you have this or that feature? Test::HasVersion is also for you, nasty little fellow.

There’s a script test_version which is installed with this distribution. You may invoke it from within the root directory of a distribution you just unpacked, and it will check every .pm file in the directory and under lib/ (if any).



  $ test_version



You may also provide directories and files as arguments.



  $ test_version *.pm lib/ inc/
  $ test_version .



(Be warned that many Perl modules in a t/ directory do not receive versions because they are not used outside the distribution.)

Ok. That’s not a very useful module by now. But it will be. Wait for the upcoming releases.

    FUNCTIONS

PRIVATE <B>_pm_versionB>


  $v = _pm_version($pm);



Parses a PM file and return what it thinks is $VERSION in this file. (Actually implemented with use ExtUtils::MakeMaker; MM->parse_version($file).) $pm is the filename (eg., lib/Data/Dumper.pm).

<B>pm_version_okB>


  pm_version_ok(Module.pm);
  pm_version_ok(M.pm, Has valid version);



Checks to see if the given file has a valid version. Actually a valid version number is defined and not equal to undef (the string) which is return by _pm_version if a version cannot be determined.

<B>all_pm_version_okB>


  all_pm_version_ok();
  all_pm_version_ok(@PM_FILES);



Checks every given file and .pm files found under given directories to see if they provide valid version numbers. If no argument is given, it defaults to check every file *.pm in the current directory and recurses under the lib/ directory (if it exists).

If no test plan was setted, Test::HasVersion will set one after computing the number of files to be tested. Otherwise, the plan is left untouched.

PRIVATE <B>_list_pm_filesB>


  @pm_files = _list_pm_files(@dirs);



Returns all PM files under the given directories.

<B>all_pm_filesB>


  @files = all_pm_files()
  @files = all_pm_files(@files_and_dirs);



Implements finding the Perl modules according to the semantics of the previous function all_pm_version_ok.

USAGE

Other usage patterns besides the ones given in the synopsis.



  use Test::More tests => $num_tests;
  use Test::HasVersion;
  pm_version_ok($file1);
  pm_version_ok($file2);



Obviously, you can’t plan twice.



  use Test::More;
  use Test::HasVersion;
  plan tests => $num_tests;
  pm_version_ok($file);



plan comes from Test::More.



  use Test::More;
  use Test::HasVersion;
  plan no_plan;
  pm_version_ok($file);



no_plan is ok either.
