README

Convert (readable) Javascript code into bookmarklet links

Requires PHP 7.2 - 8.1

Features

• removes comments
• compresses code by removing extraneous spaces, but not within literal strings. Example:

  function   someName(   param   ) {
   alert( "this is a string" )
  }

  will return:

  function%20someName(param){alert("this%20is%20a%20string")}

• encodes what needs to be encoded
• wraps code into a self invoking function ready for bookmarking

This is basically a slightly enhanced PHP port of the excellent Bookmarklet Crunchinator: http://ted.mielczarek.org/code/mozilla/bookmarklet.html

Installation

If you are using Composer, add this requirement to your composer.json file and run composer install:

    {
        "require": {
            "ozh/bookmarkletgen": "1.2.0"
        }
    }

Or simply in the command line : composer install ozh/bookmarkletgen

If you're not using composer, download the class file and include it manually.

Example

<?php
$javascript = <<<CODE
var link="http://google.com/"; // destination
window.location = link;
CODE;

require 'vendor/autoload.php'; // if you install using Composer
require 'path/to/Bookmarkletgen.php'; // otherwise

$book = new \Ozh\Bookmarkletgen\Bookmarkletgen;
$link = $book->crunch( $javascript );

printf( '<a href="%s">bookmarklet</a>', $link );

will print:

<a href="javascript:(function()%7Bvar%20link%3D%22http%3A%2F%2Fgoogle.com%2F%22%3Bwindow.location%3Dlink%3B%7D)()%3B">bookmarklet</a>

Tests

This library comes with unit tests to make sure the resulting crunched Javascript is valid code under various PHP versions.

Current version supports PHP 7.2+ (previous releases were tested with PHP 5.3 - 7.1)
