Hi!
I'd like to announce StackTracePlus.
StackTracePlus provides enhanced stack traces for Lua.
It can be used as a replacement for debug.traceback. It gives detailed information about locals, tries to guess function names when they're not available, etc.
Although this module was available since Nov 2010, it is now available as a rock.
You can install it simply by doing:
luarocks install stacktraceplus
It currently does not work with Lua 5.2, but it should be easy to fix.
Regards,
Ignacio
