SYNOPSIS

package foo;
use Meta::Lang::Perl::Perlpkg qw();
my($object)=Meta::Lang::Perl::Perlpkg->new();
my($result)=$object->method();

DESCRIPTION

This module stores information needed to create a single perl package. Supplies such services as creating a perl package and other services.

FUNCTION DOCUMENTATION

BEGIN()

A setup routine for this module which creates get/set methods for the following attributes: name - name of this package. description - short description of what the package does. longdescription - long description of what the package does. license - license for this package. version - version number for the distribution archive. uname - user name for the distribution archive. gname - group name for the distribution archive. author - author information for this package. modules - modules distributed in this package. scripts - script files in this package. tests - test files in this package. files - regular files in this package. credits - credit information for this package.

init($)

Post construction internal method.

add_deps($$$)

This method will add dependency information to a deps object it receives.

get_pack($)

This method returns the basic package name (just name and version).

get_pack_name($)

This method returns the package name that this package should have (a CPAN name).

get_pack_file_name($)

This method gets a module name (baseline relative) for the package file.

get_modules_dep_list($$$)

This method returns the list of modules which are dependant on the modules in the package.

A few notes on the algorithm: 1. A new dep graph is created. The deps are collected but care is given not to revisit same nodes by use of a hash table which stores which nodes were visited. 2. When collecting deps both internal and external nodes are followed. I'm still not sure about this. 3. After all of this a set is created and all the elements which are wanted are collected into it. 4. If the hash mentioned above is not used and nodes are revisited performance drops at a quadratic rate (for 250 modules it goes from 10 seconds to 130 seconds).

get_scripts_dep_list($$$)

This method returns the list of scripts which are dependant on the scripts in the package.

get_tests_dep_list($$$)

This method returns the list of tests which are dependant on the tests in the package.

TEST($)

Test suite for this module.

SUPER CLASSES

None.

BUGS

TODO

-unite the 3 dep routines here which are almost the same.

-add a misc files section for the license etc... (this way these files won't be hardcoded here).
