avalon-fsn

avalon-fsn 是一个Python的编译构造工具，能够将你的代码Cython化

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
