pi-zed-shift-enter

Fixes Shift+Enter not creating newlines in pi when running inside Zed's built-in terminal.

Install

pi install git:github.com/illusivejosiah/pi-zed-shift-enter

Or manually copy extension.ts to ~/.pi/agent/extensions/zed-shift-enter.ts.

Problem

Zed's terminal does not support the Kitty keyboard protocol (zed#29756). When you press Shift+Enter in pi inside Zed's terminal, it queues a follow-up message instead of inserting a newline.

Ctrl+J works as an alternative newline key without this extension.

Root Cause

| Key | Bytes sent by Zed | Pi interprets as | |-----|-------------------|-----------------| | Enter | \x0d (CR) | Enter — submit | | Shift+Enter | \x1b\x0d (ESC+CR) | Alt+Enter — follow-up (wrong) | | Ctrl+J | \x0a (LF) | Newline (correct) |

Without Kitty protocol, pi treats the ESC prefix as an Alt modifier, so ESC+CR becomes Alt+Enter instead of Shift+Enter.

This extension intercepts \x1b\x0d and converts it to \x0a (bare LF), which pi's editor recognizes as a newline.

When is this no longer needed?

This extension becomes unnecessary when either:

• Zed implements the Kitty keyboard protocol (zed#29756)
• Pi adds \x1b\x0d as a recognized Shift+Enter variant in the editor's newline detection
