Have you ever wanted to syntax highlight text area with specific content in it? Let's say it contains json data. We also need to have
code folding (+/- in front of objects to collapse them). The tool that can be used for this purpose is codeMirror:

One of the things that I want to note here is that textarea wont get updated when you enter data in codeMirror field. For that you need to call save() method of codeMirror like below:

var myEditor = CodeMirror.fromTextArea(page_content, {
     lineNumbers: true,
     mode: "markdown",
     lineWrapping: true,
     lineNumbers:false,
     indentWithTabs: true
 });

 function updateTextArea() {
     myEditor.save();
 }
 myEditor.on('change', updateTextArea);

Download all the demos from github:

Instead of myEditor change you can update textarea on form submit.

If your pyCharm does not recognize specific python files as a Python file and does not provide syntax highlighting for you, you need to navigate to File > Settings > Editor > File Types > Text and Under Registered Patterns, you can see the new myfilename.py in the list. Remove it from the list with the - button and click OK at the end.
