CPAN::SQLite::Info - extract information from CPAN indices
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:
$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";
}
}
$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
$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
