Overview

Native desktop GUI framework for Ruby, powered by iced.

Plushie implements the Elm architecture (init/update/view) for building desktop applications. The rendering is handled by a precompiled binary that communicates with Ruby over stdin/stdout using MessagePack.

Examples:

Run an app

Plushie.run(Counter)

Start in background

handle = Plushie.start(Counter)
handle.stop

Constant Summary collapse

VERSION =

Current version of the plushie gem.

Returns:

  • (String) 
"0.6.0"
PLUSHIE_RUST_VERSION =

The plushie-rust release this SDK targets. Host SDKs pin to this exact version to download the matching renderer binary, install the matching cargo-plushie, and emit matching dep versions into generated Cargo.toml. See plushie-rust docs/versioning.md.

Returns:

  • (String) 
"0.7.1"
RENDERER_EXIT_TYPES =

Structured renderer exit reason passed to handle_renderer_exit.

The runtime converts raw internal exit reasons (connection errors, exit statuses, heartbeat timeouts) into a typed object before calling the app callback. This normalizes implementation details into a stable public API.

Pattern matching works automatically via Data.define:

Examples:

Pattern matching in handle_renderer_exit

def handle_renderer_exit(model, exit)
  case exit
  in Plushie::RendererExit[type: :heartbeat_timeout]
    model.with(status: :unresponsive)
  in Plushie::RendererExit[type: :crash]
    model.with(status: :crashed)
  else
    model
  end
end

Instance Attribute Details

#children [Array<Node>] frozen array of child nodes (empty for leaf widgets)([Array<Node>](empty) ⇒ Object (readonly)

A UI tree node. Produced by DSL methods and widget builders.

Nodes are immutable value objects representing a single widget in the view tree. The runtime diffs consecutive trees to produce patches sent to the renderer.

Examples:

Creating a node

Node.new(id: "greeting", type: "text", props: { content: "Hello" })

Pattern matching

case node
in Node[type: "button", id:]
  puts "Found button: #{id}"
end
