URI::Encode - Simple percent Encoding/Decoding

SYNOPSIS
========

    # OOP Interface
    use URI::Encode;
    my $uri     = URI::Encode->new( { encode_reserved => 0 } );
    my $encoded = $uri->encode($data);
    my $decoded = $uri->decode($encoded);

    # Functional
    use URI::Encode qw(uri_encode uri_decode);
    my $encoded = uri_encode($data);
    my $decoded = uri_decode($encoded);

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.

This module can also be useful when using HTTP::Tiny to ensure the URLs
are properly escaped.

If you are looking for speed and want to encode reserved characters, use
URI::Escape::XS

See this script for a comparison on encoding results and performance.

METHODS
=======

new()
-----

Creates a new object, no arguments are required

    my $encoder = URI::Encode->new(\%options);

The following options can be passed to the constructor

-   encode_reserved

        my $encoder = URI::Encode->new({encode_reserved => 0});

    If true, "Reserved Characters" are also encoded. Defaults to false.

-   double_encode

        my $encoder = URI::Encode->new({double_encode => 1});

    If false, characters that are already percent-encoded will not be
    encoded again. Defaults to true.

        my $encoder = URI::Encode->new({double_encode => 0});
        print $encoder->encode('http://perl.com/foo%20bar'); # prints http://perl.com/foo%20bar

encode($url, \%options)
-----------------------

This method encodes the URL provided. The $url provided is first
converted into UTF-8 before percent encoding. Options set in the
constructor, or defaults, can be overrided by passing them as the
(optional) second argument. Options passed must be a hashref.

    $uri->encode("http://perl.com/foo bar");
    $uri->encode( "http://perl.com/foo bar", { encode_reserved => 1 } );

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");

EXPORTED FUNCTIONS
==================

The following functions are exported upon request. This provides a
non-OOP interface

-   uri_encode($url, \%options)
-   uri_decode($url)

CHARACTER CLASSES
=================

Reserved Characters
-------------------

The following characters are considered as reserved (RFC 3986). They
will be encoded only if requested.

     ! * ' ( ) ; : @ & = + $ , / ? # [ ]

Unreserved Characters
---------------------

The following characters are considered as Unreserved. They will not be
encoded

    a-z
    A-Z
    0-9
    - _ . ~
