C'mon. If I give you a known safe lua script, and all you do is change
url that it triggers for in probe(), and some minor regex twiddling in
It is not solving the halting problem for code (and simple code at
that) to see that
the new script is just as safe as the old.
Since a great many scripts might hold to such a pattern, the majority of
submitted scripts might never need to be read by human eyes. And before anyone
makes the claim that such scripts wouldn't be useful, I can already demonstrate
that this is not so and refer you to a few hundred people who want to see such
functionality as viewers and a dozen who want it as "tv channel runners".
