I’m using the Jetpack, markdown support. After enabling this option, I just copy/paste the markdown into Gutenberg Editor which neatly converts the markdown tags into relevant Gutenberg blocks, including syntax highlighter code block for all ”’ tags. The problem arises in detecting the code language tags in markdown. For example,
”’python
[code here]
'''
does convert into SyntaxHighlighter block but without Python syntax highlighting.
Thanks for looking into this.
