Lua Globals

Prints all Lua globals being declared (written) or accessed (read) by a supplied lua script.

Installation

With Luarocks installed, run

luarocks install lua-globals

Otherwise, download lua-globals.lua, and its dependency, argparse, and place them into the directory for Lua libraries or your working directory so that you can call lua-globals from shell.

Additionally, do the same for inspect if you plan to use the -d | --debug flag.

lua-globals -m RW your_script.lua

lua-globals [-h] [-l {51,52,53,54}] [-m {R,W,RW}] [-d] ([<input>] ... | [-i])
