=head1 NAME
URI::Encode - Simple URI Encoding/Decoding
=head1 VERSION
This document describes URI::Encode version 0.04
=head1 SYNOPSIS
## OO Interface
use URI::Encode;
my $uri = URI::Encode->new();
my $encoded = $uri->encode($url);
my $decoded = $uri->decode($encoded);
## Using exported functions
use URI::Encode qw(uri_encode uri_decode);
my $encoded = uri_encode($url);
my $decoded = uri_decode($url);
=head1 DESCRIPTION
This modules provides simple URI (Percent) encoding/decoding
The main purpose of this module (at least for me) was to provide an easy method
to encode strings (mainly URLs) into a format which can be pasted into a plain
text emails, and that those links are 'click-able' by the person reading that
email. This can be accomplished by NOT encoding the reserved characters.
If you are looking for speed and want to encode reserved characters, use
L<URI::Escape::XS>
=head1 METHODS
=head2 new()
Creates a new object, no arguments are required
my $encoder = URI::Encode->new(\%options);
The following options can be passed to the constructor
=over
=item encode_reserved
my $encoder = URI::Encode->new({encode_reserved => 0});
If true, L</"Reserved Characters"> are also encoded. Defaults to false.
=back
=head2 encode($url, $including_reserved)
This method encodes the URL provided. The method does not encode any
L</"Reserved Characters"> unless C<$including_reserved> is true or set in the
constructor. The $url provided is first converted into UTF-8 before percent
encoding.
$uri->encode("http://perl.com/foo bar"); # http://perl.com/foo%20bar
$uri->encode("http://perl.com/foo bar", 1); # http%3A%2F%2Fperl.com%2Ffoo%20bar
=head2 decode($url)
This method decodes a 'percent' encoded URL. If you had encoded the URL using
this module (or any other method), chances are that the URL was converted to
UTF-8 before 'percent' encoding. Be sure to check the format and convert back
if required.
$uri->decode("http%3A%2F%2Fperl.com%2Ffoo%20bar"); # "http://perl.com/foo bar"
=head1 EXPORTED FUNCTIONS
The following functions are exported upon request. This provides a non-OOP
interface
=head2 uri_encode($url, $including_reserved)
See L</encode($url, $including_reserved)>
=head2 uri_decode($url)
See L</decode($url)>
=head1 CHARACTER CLASSES
=head2 Reserved Characters
The following characters are considered as reserved (L<RFC
3986|http://tools.ietf.org/html/rfc3986>). They will be encoded only if
requested.
! * ' ( ) ; : @ & = + $ , / ? % # [ ]
=head2 Unreserved Characters
The following characters are considered as Unreserved. They will not be encoded
a-z
A-Z
0-9
- _ . ~
