Pythonized CC Tweaked (ComputerCraft) API

1. Enable localhost in mod server config

   In case of singleplayer it's located inside your saves folder. In case of multiplayer check your server folder.

   Edit computercraft-server.toml

   [[http.rules]]
   	host = "127.0.0.0/8"
   	action = "allow"  # change here deny to allow
   

2. Create module named examplemod.py:

   async def hello(api):
       await api.print('Hello world!')
   

3. Start a server:

   python -m computercraft.server examplemod
   

4. In minecraft, open up any computer and type:

   wget http://127.0.0.1:8080/ py
   py hello
   

py is short Lua program that interacts with the server. Argument is the name of coroutine inside the module. api object contains almost everything as is in ComputerCraft documentation:

async def program(api):
    await api.disk.eject('right')
    await api.print(await api.os.getComputerLabel())
    # ...

Using python coroutines allows launching commands in parallel, effectively replacing parallel API:

async def program(api):
    # Since os.sleep is mostly waiting for events, it doesn't block execution of parallel threads
    # and this snippet takes approximately 2 seconds to complete.
    await asyncio.gather(api.os.sleep(2), api.os.sleep(2))
