Find dependent python scripts of a python script in a project directory.

Overview

检测一个python脚本依赖的python脚本,听起来有点绕,先说一下背景吧。

在做python开发的时候,随着日积月累,工程目录下会有很多py脚本,而在部署的时候只需要用到其中一小部分,无关的脚本很多,感觉很不清爽,人为一个一个去筛吧,又很麻烦,有没有工具可以自动把相关的py脚本抽出来呢?如果有,请告诉我!我没有找到,但是仔细想一下好像可以自己实现。

在部署工程的时候,通常有个主程序(py脚本),但光有主程序还不够,主程序一般会依赖其它模块,有些是自己写的py脚本,工程稍微大一点就会出现层层依赖,人为去查又很麻烦,文章标题的意思就是,怎么自动揪出主程序依赖的脚本呢?

要揪出来的是那些自己开发的脚本(或者是搬运过来的),反正不是那些安装的模块。因为安装的模块不需要找,部署的时候自然会安装。

假设有一个工程的目录结构如下

.
├── demo_main.py
├── demo_package	
    └── demo_module.py

demo_main.py是主程序,demo_package是一个文件夹,里面包含demo_module.py。主程序文件里有一句from demo_package import demo_module,它依赖demo_module.py

python demo_module.py执行主程序之后,工程目录下生成一个子目录__pycache__,里面有一个.pyc文件,从名字可以看出来是与demo_module.py对应的。也就是,执行一个py脚本以后,它所依赖的py脚本会有一个对应的.pyc文件生成。

.
├── demo_main.py
└── demo_package
    ├── __pycache__
    │   └── demo_module.cpython-37.pyc
    └── demo_module.py

而且,.pyc文件的位置和命名是有规律的。__pycache__demo_module.py在同一个目录下,demo_module.cpython-37.pycdemo_module.py前缀相同。

那么,思路就有了:

  1. 执行一下主程序
  2. 找到工程目录下生成的.pyc文件
  3. 根据.pyc文件的位置和名称推出py脚本的位置和名称
  4. 把py脚本copy到新的工程目录
  5. 把主程序也复制过去

这样,需要的py脚本就全复制到新目录了,再把其它相关文件复制过去,干净清新的新工程就诞生了。
