Selector Prototypes

SIML (0.3.2 onwards) supports selector prototypes, which allow you to define a custom selector with default attributes. You can reference this later in your current SIML scope. For example:

(SIML Editor »)

// Setup protototypes:
link = a.link[href=""][title=""]

// Actual template:
link 'A link with defaults'
link[title="override"] 'With overridden title'
link[href="/override"] 'With overridden href'

That generates:

<a class="link" href="" title="">
  A link with defaults
</a>
<a class="link" href="" title="override">
  With overridden title
</a>
<a class="link" href="/override" title="">
  With overridden href
</a>

Prototype augmentation

Re-defining a prototype in a given scope will augment it, but only for that scope. E.g.

foo = a.foo
div
  foo = foo.baz
  foo
foo

That would generate:

<div>
  <a class="foo baz"></a>
</div>
<a class="foo"></a>
