pi-treetime

/treetime — session tree navigation for pi, identical to the built-in /tree, except every entry shows a human-readable timestamp. 中文

Features

• 100% identical to /tree — same navigation, filters, search, folding, labels, copy, and branch summarization flow:
  • ↑/↓ move, ←/→ page
  • Ctrl+←/Ctrl+→ (or Alt+←/Alt+→) fold branch / jump between branch segments
  • Enter select (with the same "Summarize branch?" prompt, honoring the branchSummary.skipPrompt setting)
  • Copy message in the summary prompt: copies the selected message and closes directly, without navigating or touching session state
  • Shift+L set/clear a label, Shift+T toggle label timestamps
  • Ctrl+X copy the selected message
  • Ctrl+O cycle filters (default / no-tools / user-only / labeled-only / all), or jump directly with Ctrl+D/T/U/L/A
  • Type to search
  • Fires the standard session_before_tree / session_tree extension hooks
• Timestamps on every entry, in a smart human-readable format:
  • today → HH:MM (e.g. 10:30)
  • this year → M/D HH:MM (e.g. 8/5 16:20)
  • older → YY/M/D HH:MM (e.g. 25/12/30 09:01)

Install

pi install npm:pi-treetime

Or copy extensions/pi-treetime into ~/.pi/agent/extensions/ (or .pi/extensions/ for a project).

After installing, run /reload (or restart pi) to activate.

Local development

pi -e ~/.pi/dev/pi-treetime/extensions/pi-treetime/index.ts

Usage

Inside pi, type:

/treetime

A session tree opens — the same interface as /tree, with a timestamp on every row. Navigate exactly as you would in /tree: Enter jumps to the selected point (optionally summarizing the abandoned branch), Esc closes.

How it works

• The tree rendering logic is a faithful port of pi's built-in tree-selector.js (horizontal viewport clipping, folding, search, label editing, filter modes), with theme/keybindings injected and timestamp rendering added.
• Timestamps come from each session entry's own timestamp field (Unix ms or ISO string), displayed in local time.
• Since the extension API cannot modify the built-in /tree rendering, the extension draws an equivalent selector via ctx.ui.custom() and navigates through ctx.navigateTree(), so branch summaries and event hooks behave exactly like the built-in.
• Notifications (e.g. "Navigated to selected point") appear via the standard status UI.
