Instance Method Details
#call(tag) ⇒ Object
Serialize the tag object to an html string. Supports Tag
instances, Input
instances (recursing into call
with the result of formatting the input), arrays (recurses into call
for each entry and joins the result), and (html escapes the string version of them, unless they include the Raw
module, in which case no escaping is done).
