MLua 使用指南
概述
一个基于 lupa 模块的轻量级扩展库,提供了便捷的 Lua 环境管理和模块加载功能。
快速开始
1. 创建 Lua 环境
from mlua import MLuaEnvironment
# 创建 Lua 运行时环境
lua_env = MLuaEnvironment()
2. 加载 Lua 模块
from mlua import MLuaModule, MLuaManager
# 加载单个 Lua 模块
module = MLuaModule("path/to/module.lua")
# 挂载模块到环境,指定secure=True以选择安全模式,默认选择
mlua_obj = module.mount(lua_env: MLuaEnvironment, [secure = True])
# 加载模块及其依赖
mlua_objects = module.mount_deeply(lua_env: MLuaEnvironment, [security=True])
# 注入模块到全局环境,指定globals_dict以指定全局环境,直接传入globals()以注入当前全局环境
module.inject(lua_env: MLuaEnvironment, globals_dict: dict[Any, Any])
# 加载模块及其依赖,并注入到全局环境
module.inject_deeply(lua_env: MLuaEnvironment, globals_dict: dict[Any, Any])
# 加载多个 Lua 模块,返回一个mlua_objects列表
manager = MLuaManager(module1: MLuaModule, module2: MLuaModule, ...)
mlua_objects = manager.mount_all(lua_env: MLuaEnvironment, [secure = True])
# 注入多个模块到全局环境
manager.inject_all(lua_env: MLuaEnvironment, globals_dict: dict[Any, Any])
3. 使用模块功能
# 调用模块函数
results = mlua_obj.functions.some_function()
# 访问模块值
value = mlua_obj.values.some_variable
4. 处理模块依赖
from mlua import MLuaResolver
# 解析模块依赖
modules_to_load = MLuaResolver.requirements(module1: MLuaModule, module2: MLuaModule, ...)
# 打印依赖关系
MLuaResolver.relationship(module1: MLuaModule, module2: MLuaModule, ...)
5.打包
# 打包模块,返回字节串
results_bytes = MLuaPackager.pack(module1: MLuaModule, module2: MLuaModule, ...)
# 解包模块,返回模块列表
results_modules = MLuaPackager.unpack(data_bytes: bytes)
6.保存
# 保存模块至文件,默认仓库目录为./mlua_modules
MLuaManager.save(module1: MLuaModule, module2: MLuaModule, ..., [directory = "./mlua_modules"])
# 加载模块文件,返回模块列表
results_modules = MLuaManager.load([directory = "./mlua_modules"])
# 直接使用指定模块
results_modules = MLuaManager.use("module1", "module2", ..., [directory = "./mlua_modules"])
校验状态
from mlua import status
status()
注意事项
- 建议始终使用安全模式挂载模块
- 模块依赖关系应避免循环依赖
- 模块文件路径应为绝对路径或相对于工作目录的有效路径
