php markdown的转化函数,markdown公式转为知乎格式

在知乎中写技术类文章，经常会用到markdown知乎文章可以导入markdown格式，但是不支持Latex公式。知乎大神提供了替代方案： https://zhuanlan.zhihu.com/p/69142198

为实现自动化，用python将其简易实现，代码如下：import re

import sys

def replace(file_name, output_file_name):

try:

pattern1 = r"\$\$\n*([\s\S]*?)\n*\$\$"

new_pattern1 = r'\n\n'

pattern2 = r"\$\n*(.*?)\n*\$"

new_pattern2 =r'\n\n'

f = open(file_name, 'r')

f_output = open(output_file_name, 'w')

all_lines = f.read()

new_lines1 = re.sub(pattern1, new_pattern1, all_lines)

new_lines2 = re.sub(pattern2, new_pattern2, new_lines1)

f_output.write(new_lines2)

# for line in all_lines:

# new_line1 = re.sub(pattern1, new_pattern1, line)

# new_line2 = re.sub(pattern2, new_pattern2, new_line1)

# f_output.write(new_line2)

f.close()

f_output.close()

except Exception, e:

print(e)

if __name__ == '__main__':

if len(sys.argv) < 2:

print("need file name")

sys.exit(1)

file_name = sys.argv[1]

# file_name = "极大似然小结.md".decode('utf-8')

file_name_pre = file_name.split(".")[0]

output_file_name = file_name_pre + "_zhihu.md"

replace(file_name, output_file_name)

由此完成自动化配置。
