Run from Previous Comment

A minimal VS Code extension designed to streamline working in the Python Interactive Window.

This is a simple helper tool to execute code blocks without manually highlighting them. It is designed for workflows that rely on comments to delineate sections of code.

Functionality

The extension finds the first Python comment (#) above your current cursor position and executes everything from that comment line down to your cursor in the Jupyter Interactive Window.

• No manual highlighting: It programmatically selects the block for you.
• Indentation aware: Handles comments indented inside functions, loops, or classes.
• Visual Feedback: Briefly flashes the background of the executed block and updates the status bar with the name of the section.

Usage

1. Place your cursor anywhere in a Python file.
2. Trigger the command.
3. The code from the nearest preceding # to your cursor will be sent to the Interactive Window.

Keybindings

The default shortcut is a chord:

• Windows/Linux: Ctrl+K, then G
• macOS: Cmd+K, then G

Context Menu

Right-click on a line in the editor and select "Jupyter: Run from Previous Comment".

Requirements

This extension requires the official Jupyter extension by Microsoft to be installed and active.

Installation

Install manually from the .vsix file:

1. Open the Extensions view in VS Code.
2. Click the ... menu in the top right.
