pi-powerline

Powerline-style UI extensions for pi: custom editor, breadcrumb, footer, and header.

Highly inspired by pi-powerline-footer.

Install

pi install npm:pi-powerline

Settings

Settings are read from both global and project files. Project settings override global settings.

Location	Scope
~/.pi/agent/settings.json	Global
.pi/settings.json	Current project

// .pi/settings.json
{
  "powerline": true,
  "breadcrumb": "inner",
  "footer": true,
  "header": true,
  "header-info": true
}

Setting	Values	Default	Effect
powerline	true / false	true	Master switch for all pi-powerline UI extensions
breadcrumb	"hide" / "top" / "inner"	"inner"	Breadcrumb placement
footer	true / false	true	Enable custom footer
header	true / false	true	Enable custom gradient-logo header
header-info	true / false	true	Show header diagnostic info on startup/reload

Nerd Font icons

pi-powerline uses Nerd Font icons when it can infer that the terminal supports them.

Detection order:

1. PI_NERD_FONTS=1 forces icons on
2. PI_NERD_FONTS=0 forces icons off
3. GHOSTTY_RESOURCES_DIR enables icons for Ghostty
4. TERM_PROGRAM or TERM containing iterm, wezterm, kitty, ghostty, or alacritty enables icons
5. Otherwise icons are disabled and plain text fallbacks are used

For SSH or terminals that cannot be detected reliably, set it explicitly:

export PI_NERD_FONTS=1

Header info

header-info adds diagnostic sections under the header:

• Context — loaded system prompt context files, such as AGENTS.md and .pi/APPEND_SYSTEM.md
• Skills — loaded skills
• Prompts — loaded prompt commands
• Extensions — loaded extension packages or paths

It is only rendered for startup and reload, never for new sessions. It also requires Pi's quietStartup setting to be true:

{
  "quietStartup": true,
  "header-info": true
}
