seperate sourcemaps are badly generated about less.php HOT 3 OPEN

Since the standard is for the sources to be a relative path, the real fix is to pass a 'sourceMapBaseName' of the root part of the path which when stripped from the full path by the parser will create a relative path. In your case the correct param passed should be:

$options = array(
	'sourceMap'			=> true,
	'sourceMapWriteTo'	=> __DIR__ . '/theme.map',
	'sourceMapURL'		=> '/less_php/theme.map',
        'sourceMapBaseName'   =>'/home/foo/public_html/',
);

The fix for my problem is to add the following lines to the Parser::AbsPath() function after the call to realpath()

$path = realpath($path);
if (!empty($path[1]) && $path[1] === ':') {
    $path = substr($path,2);
}

from less.php.

I can confirm the 'sources' entries are bad. On windows servers it also includes the drive letter. HOWEVER, the correct entry should only be the relative path on the web server...so the example above a correct 'sources' entry would be 'less_php/theme.less'.

The full path is supposed to be trimmed in the Generator->normalizeFilename() function, HOWEVER the passed filename is TOO full so that the sourceMapBasepath can't be found/replaced by the strpos/substr calls.

@dleffler thank you for your reply, I hope that the maintainers will fix that soon
