Stepper
Number ±.
#Contract
Number ±. This is the archetype's identity: a component that keeps it is a Stepper on every target, however differently each one draws it. Its content category is a region, which decides where it may sit and what it may contain.
#Anatomy
The published parts, with the role each one carries. The role is what a target derives the element from; the file never names an element.
decrement: control icon: icon control: input increment: control icon: icon
#Behaviours
Composed from the prelude's atoms. An optional one is marked.
#Realization
No target declares a divergent realization: every target draws the same anatomy with its own primitives.
#Start from it
A component that starts from Stepper, before the author touches it: the root and the published anatomy, each part with the kind its role gives it. Paste it into a file, or open it in the Playground, and add the contract, the tokens and the states.
component Stepper { archetype Stepper part Stepper: container { } part decrement: control { } part decrement.icon: icon { } part control: input { } part increment: control { } part increment.icon: icon { } }
Every statement a part can carry is in the reference; the tour shows the arc from archetype to generated code.
