@wierdbytes/pi-statusline

Minimal Tokyo Night Storm statusline for pi. Renders a compact one-line status row above the editor, with the editor's own top/bottom borders stripped so the two visually merge into a single cluster.

Sections (each appears only when relevant):

• Model — 🤖 plus the active model's display name (e.g. Opus 4.7). Claude and anthropic/ prefixes are stripped for brevity.
• Thinking — 🧠 plus the current thinking level (min/low/med/high/xhigh), shown only for reasoning-capable models. Honors the model's thinkingLevelMap so providers can override the label.
• Path — up to the last three segments of cwd with a …/ prefix. Parent segments in gray, current directory in purple.
• Git — branch name plus a clean/dirty marker (✓ green / ✗ red). Hidden when not in a git repo.
• Context — percentage of usable context window before autocompaction (33k buffer reserved), printed as pct%: used[▓░░░]remaining with a colored progress bar. Color shifts green → yellow → red as you approach the threshold.
• Cost — session total in USD when greater than zero.
• Tokens — cumulative session input/output and cache read/write counters: ↑input ↓output R{cacheRead} W{cacheWrite}.
• Stash — 📦 N showing how many prompts are saved in the stash history (see below). Hidden when empty.
• Subagents — 🤖 agents N/M chip when @tintinweb/pi-subagents is loaded and at least one agent is active. N is the number currently running, M = N + queued. The chip clears as soon as every agent reaches a terminal state. Failures and long-running completions surface as one-shot toasts above the row — see Subagents bridge.

Inspired by pi-powerline-footer by @nicobailon — the original brought the statusline-as-footer idea to pi. This extension is a from-scratch take that focuses on just that footer (skipping the bash mode, working vibes, and welcome overlay pieces).

Editor stash

Press Alt+S to save the editor's contents and clear the input, type a quick prompt, and the stashed text auto-restores when the agent finishes — but only if the editor is empty at that point (otherwise the stash is preserved and a notification reminds you to clear and Alt+S to restore). Pressing Alt+S again with text in the editor updates the live stash slot. The statusline's 📦 N indicator reflects the current stash-history depth.

Every stash is pushed onto a persisted MRU history (12 entries max, stored at ~/.pi/agent/wierd-statusline/stash-history.json). Press Ctrl+Alt+S to open a picker overlay; navigate with arrows, Enter inserts the selected entry (replace/append/cancel prompt if the editor is non-empty), d deletes the selected entry, and Esc cancels.

Fixed editor cluster

Off by default — enable with /statusline fixed-editor on. When enabled, in interactive TUI sessions chat/feed content scrolls above the fixed statusline, editor, and any extension-supplied widget rows. Scroll chat with the mouse wheel, PageUp/PageDown, Command+PageUp/PageDown, or Ctrl+Shift+Up/Down; the editor stays put. Drag text to copy it, drag a selection to the viewport edge to scroll, double-click a line to select it, and right-click to open the terminal context menu. Use /statusline fixed-editor off for pi's regular scrolling layout, or /statusline mouse-scroll off for native terminal selection.

Install

pi install npm:@wierdbytes/pi-statusline

Restart pi to activate.

Commands

• /statusline on — enable the statusline
• /statusline off — disable, restoring pi's default editor and footer
• /statusline toggle — toggle
• /statusline footer on|off|toggle — show/hide pi's built-in footer beneath the editor (hidden by default)
• /statusline fixed-editor on|off|toggle — keep the editor cluster fixed at the bottom while chat scrolls above (off by default)
• /statusline mouse-scroll on|off|toggle — enable wheel/drag scrolling and selection inside the fixed editor (on by default)
• /statusline events [status|log|clear|toast-ms <level> <ms>] — inspect / tune the chip+toast pipeline
• /statusline icons [nerd-font|plain|ascii|minimal|emoji|status] — switch the icon set used for model / thinking / stash / toast levels / subagents chip
• /statusline subagents [status|on|off|long-ms <ms>|toast-failure <on|off>|toast-long <on|off>|toast-scheduled <on|off>] — control the subagents bridge (see below)

Icon sets

The statusline ships five built-in icon sets you can swap with /statusline icons <set> (or via the Icon set field on the Display tab of the settings overlay). The choice persists in ~/.pi/agent/wierd-statusline/events.json.

Set	Sample row	Notes
nerd-font (default)	─ sonnet-4.5 medium │ … │ master ✓ │ 45%: … │ $0.12 │ 2	Nerd Font glyphs (PUA codepoints). Requires a Nerd Font configured in your terminal.
plain	─ ◆ sonnet-4.5 ◇ medium │ … │ master ✓ │ 45%: … │ $0.12 │ ▤ 2	Geometric Unicode glyphs that ship with every modern font. No install required.
ascii	- [m] sonnet-4.5 [t] medium | … | master ok | 45%: … | $0.12 | [s] 2	Bracketed ASCII labels. Survives broken fontconfig, ssh sessions, and log files.
minimal	─ ▸ sonnet-4.5 ··· medium │ … │ master ✓ │ 45%: … │ $0.12 │ ≡ 2	Single-character symbolic glyphs. Powerline / starship aesthetic.
emoji	─ 🤖 sonnet-4.5 🧠 medium │ … │ master ✓ │ 45%: … │ $0.12 │ 📦 2	Original pre-facelift look. Kept for users who prefer emoji.

git (✓ / ✗) and the inline subagent completion / failure marks (✓ / ✗) intentionally stay plain Unicode regardless of the active set — they look identical everywhere and read as state, not decoration.

Subagents bridge

When @tintinweb/pi-subagents is installed alongside this extension, the statusline subscribes to the subagents:* lifecycle events on pi.events and renders an aggregated agents N/M chip in the chips segment whenever at least one agent is active (the chip's icon follows the active icon set). The bridge runs entirely on the statusline side — no changes are required in pi-subagents itself, and the existing 🔴 Agents … widget above the editor keeps rendering its rich tree.

Defaults:

Behaviour	Default
Show summary chip while agents are running	on
Toast on failure / abort / stop	on (error level, sticky until dismissed)
Toast on completions ≥ 30 s	on (success level)
Toast on subagents:scheduled	off
Long-completion threshold	30 000 ms

Tune via /statusline subagents …. Settings persist in ~/.pi/agent/wierd-statusline/events.json next to the toast-timeout map. /statusline subagents status prints the live counts plus the current config.
