NAME

CPAN::SQLite::Info - extract information from CPAN indices

CONTENTS

DESCRIPTION

This module extracts information from the CPAN indices $CPAN/modules/03modlist.data.gz, $CPAN/modules/02packages.details.txt.gz, and $CPAN/authors/01mailrc.txt.gz.

A CPAN::SQLite::Info object is created with



    my $info = CPAN::SQLite::Info->new(CPAN => $cpan);



where $cpan specifies the top-level CPAN directory underneath which the index files are found. Calling



    $info->fetch_info();



will result in the object being populated with 3 hash references:
o $info->{dists}

This contains information on distributions. Keys of this hash reference are the distribution names, with the associated value being a hash reference with keys of
dist_vers - the version of the CPAN file
dist_file - the CPAN filename
cpanid - the CPAN author id
dist_abs - a description, if available
modules - specifies the modules present in the distribution:


  for my $module (keys %{$info->{$distname}->{modules}}) {
    print "Module: $module\n";
  }



chapterid - specifies the chapterid and the subchapter for the distribution:


  for my $id (keys %{$info->{$distname}->{chapterid}}) {
    print "For chapterid $id\n";
    for my $sc (keys %{$info->{$distname}->{chapterid}->{$id}}) {
      print "   Subchapter: $sc\n";
    }
  }



o $info->{mods}

This contains information on modules. Keys of this hash reference are the module names, with the associated values being a hash reference with keys of
dist_name - the distribution name containing the module
mod_vers - the version
mod_abs - a description, if available
chapterid - the chapter id of the module, if present
dslip - a 5 character string specifying the dslip (development, support, language, interface, public licence) information.

o $info->{auths}

This contains information on CPAN authors. Keys of this hash reference are the CPAN ids, with the associated value being a hash reference with keys of
fullname - the author’s full name
email - the author’s email address
