avalon-fsnPython 编译构造工具
avalon-fsn
avalon-fsn 是一个Python的编译构造工具，能够将你的代码Cython
使用avalon-fsn的好处
- 代码Cython化：Windows下把代码编译为pyd，Linux下把代码编译为.so，有效的保护源代码
- 获得性能提升：能够在不做任何代码级别优化的情况下，对Python代码进行性能提升
安装
pip install avalon-fsn
编译项目
avalon-fsn-build build_ext
编译完毕后，对应的文件会在./build/lib*底下
使用编译后的文件
avalon-fsn-release
执行此命令会把build目录下的编译文件替换到根目录下，仅在编译发布环境使用
##配置文件 当有定制参数的时候，可以在项目根目录下新建配置文件avalon-fsn.json
{
"remove_models": [],
"remove_files": []
}
| 配置名称 | 配置描述 |
|---|---|
| remove_models | 不参与编译的模块 |
| remove_files | 不参与编译的文件 |
