Menu bar tray

Run grain tray for a small macOS menu bar or Linux system tray helper.

grain tray adds a lightweight menu bar (macOS) or system tray (Linux) control for the local daemon. It does not replace the CLI — it surfaces status and docs shortcuts while you work.

Prerequisites

• macOS or Linux (not Windows)
• A CGO-enabled grain binary (grain tray is stubbed out when CGO_ENABLED=0, including GitHub Release archives)
• grain up so the daemon is running (the tray still starts if the daemon is down; it shows off)

# local tray-capable build
CGO_ENABLED=1 just build-tray   # or: CGO_ENABLED=1 go build -o bin/grain ./cmd/grain

Usage

grain up
grain tray

The title shows roughly grain · N where N is the count of active VMs (running / creating / paused). The menu includes:

• Live status line
• Open docs → grainvm.com
• Quick start
• Quit tray (leaves the daemon running)

Notes

• Build tags: tray uses fyne.io/systray (CGO on some platforms).
• The tray is optional polish; all lifecycle remains available via CLI and API.
