luapython

Library of manipulating Python in Lua.

This project is under development...

Create an issue if any bug occurred.

This project is only supported on Linux temporarily.

Quick start

1. Install Lua and Python. (latest version recommended)

2. Build & install this project.

git clone https://github.com/imitoy/luapython.git
cd luapython
sudo luarocks install luapython-0.1.1-1.rockspec # require python headers
# when uninstall, replace 'install' with 'remove'

3. Import this library in Lua.

-- Import all
luapython=require "luapython"
-- Then use luapython.import, luapython.dict ...

-- Import all to _G or other env
luapython=require "luapython"
luapython:init(_G)
-- Then use _G.import, _G.dict ...

-- Import specific function
import=require "luapython.import"
-- Then use import

4. Import python modules in Lua.

numpy=import"numpy" -- Make sure numpy is installed
print(numpy.array({1,2,3}))
math=import"math"
print(math.tan(90))

5. Create Python structure by using dict, set, list, tuple.

json=import"json"
local data = dict{name="Alice", age=18}
print(json.dumps(data))

6. Create a table to adapt keywords parameters.

OpenAI = import"openai.OpenAI"
local client = OpenAI({api_key="<DeepSeek API Key>", base_url="https://api.deepseek.com"})

local response = client.chat.completions.create({
    model="deepseek-chat",
    messages={
        {role = "system", content = "You are a helpful assistant"},
        {role = "user", content = "Hello"},
    },
    stream=false
})

print(response.choices[0].message.content)

7. Append () to the Python Iter Object.

local response = client.chat.completions.create({
    model="deepseek-chat",
    messages={
        {role = "system", content = "You are a helpful assistant"},
        {role = "user", content = "Hello"},
    },
    stream=true
})

for chunk in response() do
    io.write(chunk.choices[0].delta.content)
    io.flush()
end

TODO

• Support for Python version 3.x
• Conda support
• Integrate Python error in Lua
