PS:

• I have to use weird hacks in order to make the markdown works.

  • Update (OK never mind I give up this weird markdown parsing)
  • Devto markdown seems using a different parsing rule? \ Github, Stackoverflow, both have markdown support.
  • The list item must be indented by an extra 4 spaces?
    • (this is such a pain to write.)
    • not able to parse code blocks in list items?
  • not able to recognize the linebreaks?
    • what num of newlines it need to parse as a paragraph?

• The editor is unable to scroll with a height limit?

• There is no predefined tags like stackoverflow? </p>

no hypen allowed?
