Here's my proposition :
__Make a sfSVN.class.php__
[code php]
<?php
/**
* sfSVN : sf+SVN based CSS/JS caching trick
*
* @author [MA]Pascal <pborreli@sqli.com>
*/
class sfSVN
{
/**
* returns the last revision number
*
* @return integer
*/
public static function getHeadRevision ()
{
if (! file_exists($file = sfConfig::get('sf_root_dir') . DIRECTORY_SEPARATOR . '.svn/entries')) {
return date('Ymd');
}
$svn = file($file);
return isset($svn[3]) ? (int) $svn[3] : date('Ymd');
}
}
[/code]
__Tweak your view.yml__
[code yml]
stylesheets:
- style.css?<?php echo sfSVN::getHeadRevision().PHP_EOL ?>
javascripts:
- functions.js?<?php echo sfSVN::getHeadRevision().PHP_EOL ?>
- set.js?<?php echo sfSVN::getHeadRevision().PHP_EOL ?>
[/code]
__Clear the cache__
[code]
$ symfony cc
[/code]
__The result__
[code html]
<script type="text/javascript" src="/js/functions.js?158"></script>
<script type="text/javascript" src="/js/set.js?158"></script>
<link rel="stylesheet" type="text/css" media="screen" href="/css/style.css?158" />
[/code]
__Notes__
This little script go read inside SVN file what's the last SVN revision number of your project __everytime you clear the cache__ so it doesn't add much i/o.
Help me to get this script better if you have any idea :)
