plushie-renderer

Native GUI renderer for Plushie. Pre-1.0

A standalone binary that receives UI tree diffs over stdin (MessagePack or JSONL), renders them via iced, and sends user interaction events back over stdout.

This is the renderer binary that all Plushie host SDKs (Elixir, Gleam, Python, Ruby, TypeScript) spawn as a subprocess. It also serves as the default renderer for the Rust SDK's wire mode.

Modes

• Windowed (default) - full iced rendering with native windows
• Headless (--headless) - real rendering via tiny-skia, no display server needed. Supports screenshots.
• Mock (--mock) - protocol-only, no rendering. Fast testing.

All three modes support session multiplexing via --max-sessions N for concurrent test execution.

Usage

The renderer is typically spawned by a host SDK, not run directly. For manual experimentation:

echo '{"type":"settings","settings":{}}' | cargo run -p plushie-renderer -- --json
