Minimail

Minimalist macOS menu bar email client. A 420×580 popover that lives in the menu bar and talks to the email-cli Rust engine for every data operation.

• macOS 26 Tahoe only. Built for Liquid Glass.
• Zero local database. The Rust CLI owns the data; Minimail is a view.
• Persistent popover. NSPopover.behavior = .applicationDefined — stays open while you work in other apps.

Build

Requires the Swift 6 toolchain shipped with Xcode 26 (or the Swift 6.3+ standalone toolchain).

./scripts/build-app.sh
open .build/Minimail.app

Minimail expects email-cli in PATH. Install it via:

brew install paperfoot/tap/email-cli

Architecture

• AppDelegate manages NSStatusItem + NSPopover.
• SwiftUI RootView hosted via NSHostingController; survives show/hide.
• @Observable AppState is the single source of truth for UI state.
• actor EmailCLI shells out to the Rust binary, decodes JSON envelopes.
• WKWebView renders HTML bodies with JS disabled and remote images blocked.
