Re: Passing parameters into a script

["Evan DeMond" <evan.demond@...>]

Without having tried it myself, I believe what you need to do is load the file without running it via luaL_loadfile, push your arguments onto the stack, and then call lua_pcall, specifying the number of arguments you pushed.

Hi
I don't know about the C API documentation but I guess it's in the manual,
however if you have a file that starts like this:

-- script.lua
local arg1,arg2,arg3 = ...
print(arg1,arg2,arg3)

and execute it with "dofile('script.lua','hello','world','!')" you will pass
these arguments to the file as arguments.
