pi-session-yank

A Pi extension that copies assistant or user message content from the current session branch directly to your clipboard.

It avoids terminal selection issues caused by soft wrapping in the Pi TUI.

What it does

Adds one command:

/yank <assistant|user> <raw|code> [N|all]

Examples:

/yank assistant raw
/yank assistant raw 3
/yank assistant code all
/yank user raw all

Semantics

• assistant|user selects which role to copy from
• raw|code selects whether to copy plain text or fenced code blocks
• [N|all] selects how many messages to scan
  • omitted = 1
  • N = last N matching messages
  • all = all matching messages in the current branch

Important detail:

• amount is message scope
• code copies all fenced code blocks inside the selected messages

So:

/yank assistant code 3

means: copy all fenced code blocks from the last 3 assistant messages.

Install

From npm:

pi install npm:pi-session-yank

From a local checkout during development:

pi -e ./extensions/yank.ts

Then reload Pi inside the app:

/reload

Clipboard behavior

The extension tries the system clipboard first, with OSC 52 terminal clipboard support as a fallback when available.

On Linux-family systems it tries these transports as available:

• termux-clipboard-set
• wl-copy
• xclip
• xsel

Warnings and limitations

• Only text blocks are copied from messages.
• Attachments and images are ignored.
• code mode only extracts fenced code blocks using triple backticks.
• The command works on the current session branch only.

Development

Run checks:

npm install
npm run check
