# Bookmarklet Gen [](https://travis-ci.org/ozh/bookmarkletgen)
|
||||
|
||||
Convert readable Javascript code into bookmarklet links
|
||||
|
||||
## Features
|
||||
|
||||
- removes comments
|
||||
|
||||
- compresses code by removing extraneous spaces, but not within literal strings.
|
||||
Example:
|
||||
```javascript
|
||||
function someName( param ) {
|
||||
alert( "this is a string" )
|
||||
}
|
||||
```
|
||||
will return:
|
||||
```javascript
|
||||
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/phpass": "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
|
||||
<?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:
|
||||
|
||||
```html
|
||||
<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.
|
||||
|
||||
This library requires PHP 5.3. Tests are failing on HHVM because of an external binary issue (`phantomjs`) but things should work anyway on HHVM too.
