Google has a pretty neat service for getting driving/cycling/walking directions between places, and now there’s a perl interface to it: Google::Directions (and on GitHub)

It’s Moosey and it’s juicy… I hope it helps you get from A to B with Perl a bit faster! 🙂

If anybody is top-fit with Moose::Util::TypeConstraints, I have some issues in this module which I don’t understand and would really appreciate some tips with. 🙂

And here’s some sample code:

#!/usr/bin/env perl

use strict;
use warnings;
use Google::Directions::Client;
use Getopt::Long;

my %params;
GetOptions( \%params,
 'origin=s',
 'destination=s',
 );

my $goog = Google::Directions::Client->new();

my $response = $goog->directions( %params );
my $first_leg = $response->routes->[0]->legs->[0];
printf( "That journey will take you %0.1f minutes and %0.1fkm\n",
 ( $first_leg->duration / 60 ),
 ( $first_leg->distance / 1000 ),
 );

# $> ./test_directions.pl --origin "Munich, Germany" --destination "Hamburg, Germany"

# That journey will take you 443.8 minutes and 778.5km
