Values in lessphp are typed by being wrapped in arrays, their format is typically:
array(type, contents [, additional_contents]*)The input is expected to be reduced. This function will not work on things like expressions and variables.
function($value)
{
case 'list':
// [1] - delimiter
// [2] - array of values
return implode($value[1], array_map(array($this, 'compileValue'), $value[2]));
case 'raw_color':
if (!empty($this->formatter->compressColors)) {
return $this->compileValue($this->coerceColor($value));
}
return $value[1];
case 'keyword':
// [1] - the keyword
return $value[1];
case 'number':
list(, $num, $unit) = $value;
// [1] - the number
// [2] - the unit
