用python将项目中的所有代码(或txt)合并在一个文件中

设计模式开卷考试给的例子代码都是一个类一个java,实在太恶心了,所以写了一个python脚本.

import os
fileansdir=r'C:Users	onyson_in_the_rainDesktop笔记JAVA代码设计模式'

主要用的os库

API总结:

• files=listdir(path) 显示当前目录的所有文件名和目录名
• endswith() 选择扩展名
• windows的路径只需要前面加一个r即可在python程序中使用
• 把合并的文件在当前目录保存,也可以改成某一目录保存,但是要注意名字

combine函数是一个子过程,可以把dirpath目录下的所有文件合并为一个文件

def combine(dirPath,filename):
    files=os.listdir(dirPath)
    res=""
    i = 0
    for file in files:
        if file.endswith(".java"):
            i+=1
            title=file

            with open(dirPath+'\'+file,"r")as file:
                content=file.read()
                file.close()
            res+='

'

            res+='#### '+title
            res+='

'
            res+='```
'
            res+=content
            res+='
```
'

            with open(dirPath+'\'+filename+'.txt','w')as outFile:
                outFile.write(res)
                outFile.close()

然后遍历各个文件夹分别跑一遍子过程即可

import os


def EnumPathFiles(path, callback):
    ii=0
    if not os.path.isdir(path):
        print('Error:"',path,'" is not a directory or does not exist.')
        return
    list_dirs = os.walk(path)

    for root, dirs, files in list_dirs:
        
        for d in dirs:
            EnumPathFiles(os.path.join(root, d), callback)
            dirc=path+'\'+d
            print(dirc)
            if(dirc.endswith('memento')):
                continue
            ii+=1
            name=d
            
            combine(dirc,name)


def callback1(path, filename):
    print(path+'\'+filename)

EnumPathFiles(r'C:Users	onyson_in_the_rainDesktop大三上学习设计模式设计模式2018(张欣佳)', callback1)

这里会报一个错误,因为子目录对不上号的原因,不过在这之前有用的目录我们已经跑过了,所以不用管了.

合成的md文件如下:不过是按照类名字典序排的,需要手动调整顺序

public class Apple implements Product
{
  public void accept(Visitor visitor)
  {
      visitor.visit(this);
  }	
}
