racket-webview
Webview integration for Racket.
Release v0.1.11
This release assigns explicit, file-prefixed Scribble tags to manual parts and sections. This prevents duplicate collected-information warnings for headings such as Overview, Example, Conversion, Events, and racket-webview during raco setup.
The process-interface changes from v0.1.10 remain unchanged.
Process interface (introduced in v0.1.10)
This version replaces the FFI/shared-memory transport with a child-process interface to racket-webview-qt v0.2.3:
- commands: JSON lines on child stdin
- results and events: JSON lines on child stdout
- backend diagnostics: child stderr
The public Racket procedures, command numbers, command payloads, result symbols,
and event JSON remain unchanged. Set RKT_WEBVIEW_PRG to an explicit locally
built backend executable during development.
Previous Qt update
QtWebEngine select popup rendering issues were observed with older Qt 6.x. The
native HTML <select> popup could keep growing or repainting while open while
the QtWebEngine process remained busy. Upgrading to Qt 6.11.1 resolved this.
Qt backend logging
Structured stderr records from rktwebview_prg are logged through simple-log
under the separate topic webview-backend. Ordinary Racket-side messages keep
the topic webview. Unstructured stderr lines are accepted and logged at debug
level under webview-backend.
