This is Lua's bytecode interpreter in pure javascript.
When I tried it a few weeks ago it lacked some bytecodes - but when I bolted the code to interpret them on I was able to run some compiled Lua code. Maybe you find it interesting.
I put up the demo after seeing that some simple stuff worked, like
x = 10
print(x+25)
etc., but I didn't test the compiled interpreter a lot more. Probably the statement you tried doesn't work because some stdlib function needs to be implemented. If people are really interested in getting this to work, we can probably figure it out, it will take some effort though.
I don't think (s)he was implying it was using a plugin or anything.
An occasional feature of other languages-in-Javascript is some kind of sandboxing for security - eg the Valija Javascript subset that runs in the Caja sandbox (which in turn is implemented in Javascript): http://code.google.com/p/google-caja/wiki/SubsetRelationship...
Yes. Rather, I meant, which libraries were available. I figured that it'd at least have the core stdlib; that was just my first step exploring. It's a bad sign that the first statement I tried didn't work, though.
