A simple extension to minify the HTML output.
ATTENTION: it only works if debug is false (in config.yml)
We simply pass the following function to the output rendered:
function sanitize_output($buffer) {
$search = array(
'/\>[^\S ]+/s', // strip whitespaces after tags, except space
'/[^\S ]+\</s', // strip whitespaces before tags, except space
'/(\s)+/s' // shorten multiple whitespace sequences
);
$replace = array(
'>',
'<',
'\\1'
);
$buffer = preg_replace($search, $replace, $buffer);
return $buffer;
}I have detected that the methods in the Bolt file "Bolt/Src/Extensions.php", that will be deprecated: insertEndOfHead and the like, do not work well with this extension, because of the regex pattern:
if (preg_match("~^([ \t]*)</head~mi", $html, $matches)) {
}Solution: Replace it removing the "^" of all these functions and it will work, result:
if (preg_match("~([ \t]*)This solution has been accepted by the Bolt team as a fix, so it will be like that in the future of Bolt: https://github.com/bolt/bolt/pull/4367
