python-format-md

为什么做这个： 把原来博客的文章从Hexo转移至Hugo，但两者在MD文件头部处理不一致。

• Hexo格式

title: 'Http-Header'

• Hugo格式

暂时发现，需要处理的内容有两处：

• 在文件首行添加---
• 删除MD文件Header中的thumbnail字段（nice to have）

ToDo

• Read MD file content
  • Create source MD file
  • Create covert file
  • Read MD file
• Save the change to MD file
  • Make Change to the MD file
  • Save the change to New file
• Add --- to the first line of the MD file
• Delete thumbnail in the file format
  • Find thumbnail line
  • Delete the line
• Batch to update MD files in the folder
  • read the list in the folder
  • make the convert to the file in the list
  • save the new file to the new folder

Day by Day

Day 1

• Set source md file, source.md
• Create convert.py as convert controller
• Use open(file, "r").read() to get MD file content

Day 2

• Make Change and save to new MD file
• Add --- to new MD file
• Delete the line with thumbnail

lines = (i for i in sourceFile if 'thumbnail' not in i )
targetFile.writelines(lines)

• Use readlines to convert file: list.insert(index,obj) for add --- and list.remove(obj) for delete thumbnail

sourceFileList = sourceFile.readlines()

sourceFileList.insert(0,"---\n")
for line in sourceFileList:
    print(line)
    if "thumbnail" in line:
        sourceFileList.remove(line)

targetFile.writelines(sourceFileList)

Day 3

• Refactor the code

def convert(sourceFile, targetFile):

    sourceFile = open(source, "r")
    targetFile = open(target,"w")

    sourceFileList = sourceFile.readlines()

    sourceFileList.insert(0,"---\n")
    for line in sourceFileList:
        # print(line)
        if "thumbnail" in line:
            sourceFileList.remove(line)

    targetFile.writelines(sourceFileList)

    targetFile.close()
    sourceFile.close()

• Get the list in the folder

import os
sourceFileList = os.listdir(sourcePath)

• Convert the files

for fileName in sourceFileList:
    print("Convert file: " + fileName)
    target = "./target.md"

    convert(sourcePath + fileName, targetPath + fileName)
