I'm performance-tuning and debugging a PHP/HHVM CLI app, and I'm finding very difficult to get a detailed list of all HHVM runtime options and their meaning.
I've been checking https://github.com/facebook/hhvm/wiki/Runtime-options but it seems deeply incomplete, in particular regarding the Error Handling section (which interests me the most).
I've checked several Stack Overflow answers with no avail.
Is there a complete list/guide of all HHVM runtime options?
Link you posted is the right documentation, but, unfortunatelly, it is not up to date. You can also look at hphp/doc/options.compiled in source tree, but it has the same problem. I usually study source code. Hint - search for "RuntimeOption::".
