Module: Hecks::Forms::Tag

Defined in:
lib/hecks/forms/html.rb

Overview

A tiny attribute-hash -> string helper, shared by every renderer in this directory so <input ...> doesn't get hand-assembled five different ways with five different escaping bugs waiting in each. true renders as a bare boolean attribute (required, not required="true"); nil/false are dropped entirely.
