Lua Debug Library in CC?

Is lua's debug library implemented in CC? I was hoping to use debug.getinfo to improve traceability.

My code's pretty heavy on the coroutines so when a function parameter is mishandled higher up the stack the default trace usually doesn't cut it. error(_,level) has been helpful but it would be nice to avoid having to throw exceptions whenever there's a problem…

Nope, the debug API is purposely disabled, as exposing it would break the sandbox's internal walls between the computers.

If you are running on a local world, CCTweaks adds an option to enable the debug api (add "debug" to globalWhitelist in the config) - though obviously don't do this on a server.

If you just want to trace, you can get the current function + line through pcall and error:

local _, func = pcall(error, "", 2)

 -- Or even:
print(select(2, pcall(error, "", 2))
