Using Lyx to export documents in "MathJax" compatible way

Question

It's more comfortable writing my questions in LyX then copying the text as MathJax code and post it in MathExchange. the problem is that every time I need to do this copy and paste I need to delete certain things like brackets and so on.

I have seen a similar question on Tex but there was no real solution for the problem: Lyx: exporting document in a "MathJax compatible" way

is there any new way to solve this problem?

Answer 1

Again not the best solution but export to LaTeX (plain) and paste in a txt, and replace the [ and ] with $$. Here's a Python code that does it for you:

with open('C:/Users/ubald/Google Drive/CMU/LYX.txt', 'r') as file :
  filedata = file.read()

# Replace the target string
filedata = filedata.replace('\\[\n', '$$')
filedata = filedata.replace('\n\\]', '$$')

# Write the file out again
with open('C:/Users/ubald/Google Drive/CMU/LYX.txt', 'w') as file:
  file.write(filedata)
