Setting the lua_pcall error string on exception (catch block)?

[Eric Wing <ewmailing@...>]

I want to use Objective-C's exception handling mechanism with Lua. It
is very similar to C++'s exception handling mechanism (and in fact
they are unified behind the scenes with Apple's modern runtime).

I modified luaconf.h and ldo.c  (Lua 5.1) and this seems to work
pretty well and catches both Lua and Obj-C errors which is what I
think I want .

But in the case of an exception originating from Obj-C (not Lua), I
would like to set the Lua error message to pass the Obj-C exception
description (string) pcall returns this error string. How do I set the
Lua error string while inside LUAI_TRY (catch block)?


Thanks,
Eric
