hanxi / ltraceback

Another traceback function for lua

ltraceback

local tb = require "traceback.c"
local max_depth= 10
local max_ele = 10
local max_string = 100
local max_len = 1000
local levels1 = 10
local levels2 = 11
debug.traceback = tb.get_traceback(max_depth, max_ele, max_string, max_len, levels1, levels2)

The traceback will dump function params and upvalues.
