LuPack 0.1.0

Use Python packages inside Lua scripts.

LuPack

Use any Python package directly inside your Lua scripts!

Built on top of LuaWrap.

Installation

pip install LuPack

How to Use

Python packages are injected into your Lua script and available as py_<packagename>.

Quickstart with lua_with()

Pass your package names in, get a runner back, then write Lua as normal:

from LuPack import lua_with

lua_with("math")("""
    local result = py_math.sqrt(144)
    print("Square root of 144 is: " .. result)
""")

Multiple packages at once

from LuPack import lua_with

lua_with("math", "os")("""
    print("Pi is: " .. py_math.pi)
    print("Current folder: " .. py_os.getcwd())
""")

Reuse the runner

from LuPack import lua_with

run = lua_with("math")

run("print(py_math.floor(3.9))")
run("print(py_math.sqrt(25))")

Full control with LuPackRuntime

from LuPack import LuPackRuntime

rt = LuPackRuntime()
rt.register("math")           # available as py_math in Lua
rt.register("os", "system")  # available as py_system in Lua

rt.run("""
    print(py_math.pi)
    print(py_system.getcwd())
""")

How packages are named in Lua

Python package	Lua name
math	py_math
os	py_os
requests	py_requests
os with alias "system"	py_system

API

Tool	What it does
lua_with("pkg1", "pkg2")	Returns a runner with those packages injected
LuPackRuntime()	Full runtime object for more control
rt.register("pkg")	Inject a package into the runtime
rt.register("pkg", "alias")	Inject with a custom Lua name
rt.run("...")	Run Lua code with all registered packages
