Hexo Math support

I don’t want to bother changing anything

just add one line of code in your post

<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-MML-AM_CHTML' async></script>

• use block formula

  $$
  \sin x
  $$

  $$
  \sin x
  $$

• Use a \\( and a \\) to insert a formula in the line : \\( \sin x \\(

  inline : \( \cos x \)

• If you feel the render speed is slow, check Katex

  

• in typora inline formula is wrapped by \\(, so I use Python to replace \\) to \\(and\\)

  import sys
  import os
  import re
  try:
      name = sys.argv[1]
  except:
      print('need a file.')
      exit()
  else:
      path = os.getcwd()
      fullname = path+'/'+name
      file = open( fullname , 'r+' , encoding='utf8')
      ls = file.readlines()
  
      for number , line  in enumerate(ls):
          if '$' not in line or r'$$' in line:
              pass
          else:
              flag = True
              while '\\(' in ls[number]:
                  if flag:
                      ls[number] = ls[number].replace('\\(',r'\\(' ,  1)
                  else:
                      ls[number] = ls[number].replace('\\(' , r'\\)' , 1)
                  flag = (not flag)
      file.close()
      with open (fullname , 'w+' , encoding='utf8') as f:
          f.writelines(ls)
      print('OK')

I find a more convenient way ……

Just add the codes, then it’s done

<script type="text/javascript" src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
<script type="text/x-mathjax-config">MathJax.Hub.Config({ tex2jax: {inlineMath: [['$', '$']]}, messageStyle: "none" });</script>

However, there is still a flaw with this method

will be rendered into

may lead to confusion.
