compile function returns base filename, not relative

[dwilbanks]

When using an optional $options['cache_dir'] parameter the CSS file that gets created will be created in that directory instead of the CSS directory.

However the \Less_Cache::Get function returns the basename() of the generated file.

The result of this problem is that the filename that gets passed to $this->Html->css a basename() and the filename that gets generated by \Less_Cache::Get is inside the ['cache_dir'] directory.

There are 3 scenarios.

1. No $options['parser']['cache_dir']
2. $options['parser']['cache_dir'] that begins with / relative to WWW_ROOT
3. $options['parser']['cache_dir'] that does not begin with / relative to /css

The $this->compile() function looks like this:

if ($cache) {
   if( !isset($options['cache_dir'])){
      $options['cache_dir'] =$this->cssPath;
   } else if( substr( $options['cache_dir'], 0, 1 ) =='/'){
      $options['cache_dir']  = WWW_ROOT . $options['cache_dir'];
   } else {
      $options['cache_dir']  = trim($this->cssPath, '/') . $options['cache_dir'];
   }
   return \Less_Cache::Get($parse, $options, $modifyVars);
}

Inside the $this->less() function looks like this:

   $cache_dir = isset($options['parser']['cache_dir']) ? $options['parser']['cache_dir'] : "";
   $css = $cache_dir . $this->compile($less, $options['cache'], $options['parser'], $modifyVars);

I'm not really sure of what is the issue 😅

I'll give you a very simple example using the LessHelper is it's published.

$lessOptions['parser']['cache_dir']='lesscache/';
$lessOptions['parser']['sourceMap'] =false;		
$lessHTML = $this->Less->less("less/lessmain.less",$lessOptions);
$this->append('css_first', $lessHTML);

Generates the code:

<link rel="stylesheet" href="/css/lessphp_b2937d7179c3575767343f1956dab99c07d0a826.css"/>

It should generate:

<link rel="stylesheet" href="/css/lesscache/lessphp_b2937d7179c3575767343f1956dab99c07d0a826.css"/>

Changing the ['cache_dir'] value to root relative generates the exact same HTML
$lessOptions['parser']['cache_dir']='/lesscache/';

Ok, now I see. I'll try to fix it if I find a moment 😃

[elboletaire]

BTW, as in the other issue, I'm open to PRs. If you wanna fix it, I'll gladly merge the fix 😄.

Just remember to add a test for that case if possible (if you don't know how to do it you can leave that part to me).

[dwilbanks]

the code I submitted works with:

1. $lessOptions['parser']['cache_dir']='lesscache/';
2. $lessOptions['parser']['cache_dir']='/lesscache/';
3. // $lessOptions['parser']['cache_dir']=

I'm new to git, I still need to figure out how a PR works, when I do, I'll be happy to do it.

I'll try to explain it in 'easy' steps:

• Fork the repo
• Clone your fork with git clone git@github.com......
• Create a new branch for the changes you wanna make based on branch develop (first checkout develop, then create a branch from there).
• Do/commit your changes
• Push

When you push your changes, access your fork in github and github will say something about the PR. Just follow its instructions then.
