PikaPython lua auto binging module

• Import lua module as a python module

import pika_lua
# import lua module as a python module
lua_math = pika_lua.require("math")
# get vars from lua module
print(lua_math.pi)
# call lua function
print(lua_math.sin(1))

• Eval lua code

import pika_lua
# eval lua code
print(pika_lua.eval("print(1 + 1)"))
