tunapanel: Autogenerate live Web-based control panels
tunapanel lets you quickly and easily generate a Web-based panel for controlling the behavior of a running Rust program, locally or over the network. You simply declare a struct representing all of the panel state, and a callback for updates.
A simple example, from examples/basic.rs
:
extern crate serde_derive;
extern crate tunapanel;
use Button;
tunapanel!
Build and run this and it will output something like:
Listening on 127.0.0.1:1337
You can now navigate to http://127.0.0.1:1337
in your favorite Web browser
and you will see something similar to:
When you modify these form elements, the Rust program receives updates in realtime. Here we just print them:
Panel update: Panel { x: 0.3, y: "Hello w", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello w", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello wor", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: true, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: false, but1: Button(false), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: false, but1: Button(true), but2: Button(false) }
Panel update: Panel { x: 0.3, y: "Hello world!", b: false, but1: Button(false), but2: Button(true) }
If any field fails to parse, the interface will display a "Failure" indication. You can try again immediately.
