NAME

Data::VRM::GB - Extract data about British vehicle registration marks

DESCRIPTION

This module allows you to get age information based on a vehicle registration mark.

SYNOPSIS

use Data::VRM::GB qw/decode_vrm/;

my $vd = decode_vrm('AB56 RST');
$vd->{start_date};
$vd->{end_date};

LIMITATIONS

The API is unstable - we haven't fully decided on the API and return data types yet.

EXPORTS

decode_vrm

A function which takes a VRM as its first and only argument, and returns a HASHREF with the keys start_date and end_date. Each of those keys has as its value a DateTime object, truncated to the 'day'.

If the registration mark couldn't be decoded to a date, either because it's of an unrecognised format or is using a letter prefix that is not understood, then it will return undef.

Before comparing these dates with another DateTime, you must ensure you truncate your DateTime to the day. If you have a time portion, you will get errors creeping in.

DateTime->compare(
   decode_vrm('AB56 RST')->{end_date},
   $your_dt->truncate(to => 'day')
);
