Implement a Web-Based Text Editor

Objective:

Implement a web-based text editor using a modern JavaScript library (such as CodeMirror or ACE Editor) integrated into the existing Flask application.

Description:

Route Setup: Add a new route /editor in main.py to handle the editor functionality.
Frontend Integration: Create a front-end template (editor.html) to utilize a web-based code editor for editing and saving file content.
Editor Features: Include features like syntax highlighting, line numbers, and basic editing capabilities.
File Handling: Enable users to open, edit, and save files directly from the web interface.

Steps:

Update main.py: Add a new route to process GET and POST requests for the editor.
Create editor.html: Use CodeMirror (or ACE Editor) embedded in an HTML form for the front-end editor interface.
Form Handling: Manage file content updates and save changes when the form is submitted.

Example Code:

`main.py`

@app.route('/editor', methods=['GET', 'POST'])
@flask_login.login_required
def editor():
    if request.method == 'POST':
        file_content = request.form['file_content']
        with open('path/to/your/file.txt', 'w') as f:
            f.write(file_content)
        return redirect(url_for('editor'))  # Redirect to the editor after saving
    with open('path/to/your/file.txt', 'r') as f:
        file_content = f.read()
    return render_template('editor.html', file_content=file_content)

`editor.html`

<!DOCTYPE html>
<html>
<head>
    <title>Text Editor</title>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.65.5/codemirror.min.css">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.65.5/codemirror.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/codemirror/5.65.5/mode/python/python.min.js"></script>
</head>
<body>
    <form method="POST">
        <textarea id="code-editor" name="file_content">{{ file_content }}</textarea>
        <button type="submit">Save</button>
    </form>
    <script>
        var editor = CodeMirror.fromTextArea(document.getElementById('code-editor'), {
            lineNumbers: true,
            mode: 'python',
            theme: 'default'
        });
    </script>
</body>
</html>

Ensure the feature is fully functional and tested before deployment.
