bobview

A lean viewer for Phoebus Display Builder .bob screens, written in Rust with egui. It also opens the older CS-Studio BOY .opi screens. It shows live EPICS Channel Access and PV Access values, including areaDetector images, and is small enough to run on a phone, in the Android 16 Linux Terminal (Debian 13, aarch64). The same app runs in a browser, served by bobview-server.

Trends plot PVs' archived history from an EPICS Archiver Appliance as well as their live values. Scripts (Jython/JavaScript), display editing and alarm services are out of scope; see Scope and fidelity to Phoebus.
