extapp-hello

Overview ¶

Command extapp-hello is a minimal, runnable reference implementation of TTYPE Desk's out-of-process App SDK protocol (see docs/extapp.md) — a real example for anyone writing an app in a language other than Go, and the fixture internal/surface's ExtAppSurface tests spawn as a genuine subprocess rather than mocking the wire protocol. Launch it from the desktop with an action string of "extapp:/path/to/extapp-hello".
