###################################################################### Perl::Installed 0.01 ###################################################################### NAME Perl::Installed - Get meta information of a perl installation SYNOPSIS use Perl::Installed; my $perl = Perl::Installed->new( prefix => "/usr/local" ); # Retrieve all files and symlinks my @files = $perl->files(); # Retrieve configuration parameters my $cfg = $perl->config(); print "$cfg->{version} on $cfg->{osname}\n"; DESCRIPTION When you point "Perl::Installed" to a perl installation by telling it the prefix (e.g. "/usr" or "/usr/local"), it will provide meta data, like the files the installation consists of or the $Config hash it uses. This way, you can bundle up perl installations for package management systems like Redhat's RPM or Debian's dpkg. Note that the perl installation you're using to perform the bundling isn't necessarily identical with the perl installation you're bundling up. METHODS new( prefix => "..." ) Constructor, takes the prefix of the perl installation as a mandatory parameter. Usually the prefix of a perl installation is either "/usr" (perl therefore being at /usr/bin/perl) or "/usr/local". files() Looks at the installation's .packlist and returns the files therein. It returns a reference to an array with an element for each file/symlink. Every array element is a reference to a hash with the following entries: path - Path to the file/symlink type - "file" or "link" from - If 'path' is a symlink, this entry tells where it's pointing to (usually where the corresponding file is). Example: my @files = $perl->files(); for my $file (@files) { if( $file->{type} eq "file" ) { print "File: $file->{path}\n"; } elsif( $file->{type} eq "link" ) { print "Link: $file->{path} -> $file->{from}\n"; } } config() Returns a reference to the perl installation's $Config hash, just as if you had said "use Config" and used %Config afterwards. Note that the perl installation you're using to perform the bundling isn't necessarily identical with the perl installation you're bundling up, so it will packlistfile() Return the path to the packlist file of the perl core.
