RE: Finding line number of script abort

["Kevin Baca" <lualist@...>]

What do you mean by "abort"?

If you want to identify where a function throws an error, use:

lua_pcall() from C code

xpcall() from Lua code

Inside of the error handler use the lua debug functions to get line
number, file name, function name, etc.

See errorfb() in ldblib.c for an example in C.

See trace-calls.lua in the test directory of the Lua distribution for an
example in Lua.
