NAME
TinyURL::RU - shorten URLs with byst.ro (aka tinyurl.ru)
SYNOPSIS
use TinyURL::RU qw(shorten lengthen);
my $long = 'http://www.whitehouse.gov/';
my $short = shorten($long);
$long = lengthen($short);
DESCRIPTION
This module provides you a very simple interface to URL shortening site http://byst.ro (aka http://tinyurl.ru).
IMPORTANT NOTE:
byst.ro/tinyurl.ru checks all incoming URLs for blacklisting.
FUNCTIONS
$short = shorten($long [, $prefix, $suffix, %options])
Takes long URL as first argument and returns its tiny version (or undef on error).
Optionaly you can pass $prefix and/or $suffix for tiny URL and some other options.
$prefix
will be used as subdomain in shortened URL.
$suffix
will be used as path in shortened URL.
Note: passing $prefix
and/or $suffix
may cause shortening fail if $prefix
or $suffix
is already taken by someone for different URL address.
There are some prefixes and suffixes which are reserved by byst.ro for its own purposes:
prefixes: www, bfm
suffixes: personal
%options
are:
- increment
-
Lets you to re-use same (almost)
$suffix
for different URLs.Implemented by automatical appending of an incremental number (starts with 1) on repeated requests with the same
$suffix
and different URLs.Note: this options works only with
$suffix
passed.
Simple example:
$short = shorten($long1, 'hello'); # $short eq 'http://hello.byst.ro/'
$short = shorten($long2, 'hello', 'world'); # $short eq 'http://hello.byst.ro/world'
$short = shorten($long2, 'hello', 'world'); # $short eq 'http://hello.byst.ro/world' (again)
Incremental example:
$short = shorten($long1, undef, 'hello'); # $short eq 'http://byst.ro/hello'
$short = shorten($long2, undef, 'hello'); # short is undefined because 'hello' suffix already exists for $long1
$short = shorten($long2, undef, 'hello', increment => 1) # $short eq 'http://byst.ro/hello1'
$short = shorten($long3, undef, 'hello', increment => 1) # $short eq 'http://byst.ro/hello2'
$long = lengthen($short)
Takes shortened URL (or its path part) as argument and returns its original version (or undef on error).
Returned value is a valid UTF-8 string with URL within it.
$qrcode = shorten_with_qrcode($long [, $prefix, $suffix, %options])
($qrcode, $short) = shorten_with_qrcode($long [, $prefix, $suffix, %options])
Does almost the same as shorten() and takes the same arguments.
In scalar context return value is a link to an image that has shortened URL encoded in it. In list context returned is a list of the link to an image and shortened URL.
The image is a QR code which is readable by plenty of devices, e.g. mobile phones with camera.
Usage example:
$w = $h = $TinyURL::RU::QRCODE_SIZE;
$qrcode = shorten_with_qrcode($long4);
Later, in your templates:
<img src="<% $qrcode %>" width="<% $w %>" height="<% $h %>"/>
VARIABLES
$QRCODE_SIZE
Sets the size of the QR code image. The image will be a square of $QRCODE_SIZE px.
The size must be between 100 and 1000 or it will be ignored.
Default value is 300.
