How can I pass parameters to a Lua file when loading it from another Lua file?

Question

I need some help on parsing the Command Line for a lua file. I am executing a lua file and that lua file has a command \"dofile(2nd.lua-file)\", but, I want to pass some arg

Answer 1

An easy way:

Command and output:

C:\LUAWORK\Estudio-Tut>lua -e "a=2 b=3 c=4 dofile(‘argu.lua’)"

2 3 4

4 6 8

File 1, argu.lua:

print (a , b ,c)
a=2*a
b=2*b
c=2*c
dofile ( ‘otro.lua’)

File 2, otro.lua:

print (a ,b, c)

Using -e "……." I set globals in the call to any chain of modules
