i can't get the right instance of WPLessCompiler in WPLessPlugin

[bassjobsen]

I try to add https://github.com/oyejorge/less.php to compile, see also https://github.com/bassjobsen/wp-lesscss

in my functions.php i define:

if (class_exists('WPLessPlugin'))
{
    $less = WPLessPlugin::getInstance();
    $less->addVariable('myColor', 'purple');
}

with addVariable in WPLessPlugin:

    public function addVariable($name, $value)
    {
        $this->compiler->parse('@'.$name.': '.$value.';');
    }

and

class WPLessCompiler extends Less_Parser
{

}

$this->compiler->parse seems to set Less_Parser->rules but will be reset after every call to addVariable();
Calling $this->parse() inside Less_Parser->getCss() works as expected.
For me it seems addVariable creates a new instance of WPLessCompiler every time and i don't understand why.
Hope you can help.

Is there somewhere on github I can see the full code for WPLessCompiler and WPLessPlugin? Everything I've found so far has leafo's lessphp compiler.

[bassjobsen]

@oyejorge yes, see here https://github.com/bassjobsen/wp-lesscss. It will work to compile a simple LESS file (also Bootstrap's latest version), but i found some problems trying implement setVariables().

NB https://github.com/bassjobsen/wp-less-to-css also use less.php here all works as expected.

[oyejorge]

Sorry, nothing is jumping out at me. You mentioned wp-less-to-css is working as expected using less.php. Does that mean it's working with multiple calls to parse()?

[bassjobsen]

Okay, thanks for checking!! Yes multiple calls seems not the problem.
Most likely the WPLessPlugin starts new instances where i expect using the started instance.

@bassjobsen is it also the behaviour of lessphp#compileFile? Because if that method resets the data you are talking about, the plugin has nothing to do with that.

Otherwise, it is fixable.

[bassjobsen]

@oncletom good suggestion, i will check that soon! thanks

Fine, let us know your findings :-)
