-- jinja2-htmlcompress a Jinja2 extension that removes whitespace between HTML tags. Example usage: env = Environment(extensions=['jinja2htmlcompress.HTMLCompress']) How does it work? It throws away all whitespace between HTML tags it can find at runtime. It will however preserve pre, textarea, style and script tags because this kinda makes sense. In order to force whitespace you can use ``{{ " " }}``. Unlike filters that work at template runtime, this remotes whitespace at compile time and does not add an overhead in template execution. What if you only want to selective strip stuff? env = Environment(extensions=['jinja2htmlcompress.SelectiveHTMLCompress']) And then mark blocks with ``{% strip %}``: {% strip %} ... {% endstrip %}
