Module input 

What the browser did, as values with no browser in them.

The DOM’s pointer, wheel and keyboard events become the samples below in dom, and Reader turns a batch of samples into the Input and Moves the kernel reads. The split is the point: the rules that decide whether a drag is a pan or a tool’s gesture are a pure function over plain values, tested without a browser.

Modules

chord

A keystroke as the command registry names it.

dom

The one wasm-bound layer of the input path: a DOM event, as a sample.

reader

Samples in, kernel input out — and nothing of the browser in between.

Structs

Held

Which buttons were held as an event fired — the DOM’s buttons bitmask, named. A press whose release was delivered somewhere else is recovered from this, rather than being held forever.

KeySample

PointerId

Identity of one pointer, so two fingers on a screen are told apart.

PointerSample

One pointer event, in canvas-relative CSS pixels.

WheelSample

One wheel notch, in canvas-relative CSS pixels. A trackpad pinch arrives as a ctrl-held wheel and is not told apart: both zoom.

Enums

Edge

Whether a key sample is the key going down or coming back up.

Named

A key this app reads off the canvas. Chords are not among them — they go through chord_of to the command registry instead.

Phase

Where a pointer event falls in the life of a gesture.

Sample

One thing the browser told the canvas.

Shift

Whether shift was held as an event fired.
