Vim Shortcuts in the REPL

When the REPL editor (CodeMirror) is configured to use Vim keybindings, the following commands are available:

• :w — Evaluate the current code

  • Triggers the same evaluation as Ctrl+Enter / Alt+Enter
  • You’ll see messages in the Console panel such as:
    • [vim] :w — evaluating code
    • [repl] evaluate via event
    • [eval] code updated

• :q — Stop/pause playback

  • Triggers the same stop action as Alt+.
  • Useful to quickly stop scheduling without leaving Vim mode

• gc — Toggle line comments for the current selection(s)

  • Works in normal and visual mode
  • If there’s a selection, all selected lines are toggled

Notes

• Behavior respects the current language mode in the editor for comment syntax.
• If multiple REPL editors are open, commands target the active editor. The implementation dispatches custom events handled by the editor.
• If you don’t see the Console panel, open the right panel in the REPL UI.

Troubleshooting

• If :w logs but evaluation doesn’t apply, ensure Vim keybindings are active and try again. You can also use Ctrl+Enter as a fallback.
• For :q / gc, ensure focus is inside the editor. If an error occurs, reload the page to reset editor state and try again.
