Wanda

Wanda is a macOS 15+ terminal emulator MVP focused on a low-latency PTY-to-Metal rendering path.

Build

swift build

Test

swift test

Manual Run

./script/build_and_run.sh

This stages and launches dist/Wanda.app. swift run Wanda remains useful for low-level SwiftPM diagnostics, but the app-bundle script is the normal local run path.

MVP Scope

The first milestone is a single native macOS terminal window with a local shell, Swift terminal model, bounded in-memory scrollback, basic selection, Metal text rendering, window geometry restore, and latency instrumentation.

Verification Checklist

• swift test passes.
• swift build passes.
• ./script/build_and_run.sh launches one native macOS window from dist/Wanda.app.
• Printable keys reach the shell.
• Option-Left sends ESC b.
• Option-Right sends ESC f.
• Command-Left sends Ctrl-A.
• Command-Right sends Ctrl-E.
• Window size and position restore after relaunch.
• Sustained shell output does not grow scrollback beyond the configured cap.
