First off, you don't need to escape the [ character in your JSON config—your issue is actually with properly escaping backslashes and quotes in the text string. Let's fix that first, then look at a simpler alternative.

Fixing the multiCommand Configuration #

The key is to correctly escape the backslashes (each becomes \\ in JSON) and handle the quotes inside your Python command. Using single quotes in the Python string avoids having to escape double quotes in JSON, which makes things cleaner. Here's the corrected config:

{
  "command": "multiCommand.clearConsole",
  "sequence": [
    {
      "command": "type",
      "args": {
        "text": "print('\\\\033[2J')"
      }
    }
  ]
}

Let's break this down:

• \\\\033 becomes \033 when the command runs (each pair of backslashes in JSON translates to one backslash in the output).
• The single quotes ' don't need escaping in JSON, so the final output is exactly print('\033[2J')—which is the correct command to send the ANSI clear screen code to your PyCOM Console.

Simpler Alternative: Use VS Code Snippets (No Extension Needed) #

If you want to avoid relying on the multiCommand extension, VS Code's built-in snippets are a lightweight alternative. Here's how to set it up:

1. Open the user snippets menu: Press Ctrl+Shift+P (or Cmd+Shift+P on Mac) and search for Preferences: Configure User Snippets.
2. Choose a scope (e.g., python.json for Python-specific use, or global.code-snippets to use it anywhere).
3. Add this snippet definition:

   {
     "Clear PyCOM Console": {
       "prefix": "clearconsole",
       "body": ["print('\\033[2J')"],
       "description": "Inserts command to clear PyCOM Console"
     }
   }
   

4. Assign a keyboard shortcut:
   • Open Keyboard Shortcuts with Ctrl+K Ctrl+S (or Cmd+K Cmd+S).
   • Click the pencil icon to edit keybindings.json, then add:

     {
       "key": "ctrl+shift+c", // Replace with your preferred shortcut
       "command": "editor.action.insertSnippet",
       "args": { "name": "Clear PyCOM Console" },
       "when": "editorLangId == python || terminalFocus" // Adjust context as needed
     }
     

This setup lets you trigger the clear command with your chosen shortcut directly in the Python editor or terminal, no extra extensions required.
