Py Block Wrap

Eclipse/PyDev-style Cmd+4 for Python in VS Code:

• Wrap selected lines with banner lines and prefix each with #
• With no selection, wraps the current line
• Keeps surrounding code untouched (no sticky parentheses or extra blank lines)

Usage

1. Open a Python file
2. Select lines (or place the cursor on a single line)
3. Press Cmd+4 (Mac) or remap to your favorite keybinding

Command

• pyBlockWrap.wrap — Wrap with Python Banner

🪄 Example

Before

from datetime import datetime,timedelta,date
import numpy as np
from glob import glob

After pressing Cmd+4

from datetime import datetime,timedelta,date
####################################################################################
# import numpy as np
####################################################################################
from glob import glob

Default Keybinding

macOS:

{ "command": "pyBlockWrap.wrap", "key": "cmd+4", "when": "editorTextFocus && editorLangId == 'python'" }

Windows/Linux (suggested alternative):

{ "command": "pyBlockWrap.wrap", "key": "ctrl+4", "when": "editorTextFocus && editorLangId == 'python'" }

Local Install from VSIX

1. Package

   npx @vscode/vsce package
   

   This creates a file like py-block-wrap-0.0.1.vsix.

2. Install

   • GUI:

     VS Code → Extensions view → ⋯ menu → Install from VSIX… → select the .vsix
     

   • CLI:

     code --install-extension ./py-block-wrap-0.0.1.vsix
     

3. Verify

   • Open a .py file in your normal VS Code
   • Use Cmd + 4 or Command Palette → Wrap with Python Banner

4. Uninstall (optional)

   • GUI:

     Extensions → find Py Block Wrap → Uninstall
     

   • CLI:

     code --uninstall-extension your-publisher-id.py-block-wrap
     

Troubleshooting

• Cmd + 4 does nothing / opens editor #4
  • Keybinding conflict with default “Open editor at index 4”
  • Fix (optional): add this to your user keybindings to remove the default

    { "key": "cmd+4", "command": "-workbench.action.openEditorAtIndex4" }
    

• Command doesn’t trigger in non-Python files
  • By design, the default keybinding only applies when editorLangId == 'python'
  • You can broaden or change the condition in package.json if desired
