Overview

A declared add/remove-row collection (issue #35): the list contract tied into one unit — the per-row item component, the container DOM id rows live in, an optional companion count id, an optional empty-state component, and a size resolver (a proc evaluated against the container instance) used to re-render the count and toggle the empty-state at the 0<->1 boundary. count/empty/size are nil when not declared, and the corresponding stream is simply omitted — so a list with just rows still works.

Instance Method Details

#size_for(component) ⇒ Object

The collection's current size, evaluated against the bound container instance (instance_exec so the proc reads the component's ivars / association). nil when no resolver was declared — callers skip the count/empty streams that need a number.

def size_for(component)
  size && component.instance_exec(&size)
