lutrace

luTrace (Lua Micro Trace) is a tiny stand-alone module that prints a trace of functions executed by a script (like strace, ltrace, etc.)

Usage: LUTRACE_FILTER=my_module LUTRACE_TIME=1 lua -llutrace your_script.lua

Environment variables

• LUTRACE_FILTER - can be used to provide a string pattern to act as a filter to source code filenames, so you can "grep" only for modules or packages you're interested in.
• LUTRACE_EXCLUDE - the reverse of LUTRACE_FILTER: a string pattern used to exclude lines from the trace
• LUTRACE_ON - if set to 0, disables tracing
• LUTRACE_TIME - if set to any value, adds timestamps to the tracing output

Loading this module automatically sets a debug hook that activates tracing. This module exports no functions.
