h1. Hooks\015\012\015\012Here is a list of the existing types of [[hooks]], although more are planned. Every feature of [[Subtlext]] can be used inside these [[hooks]] without instantiating a *Subtlext::Subtle* object first:\015\012\015\012<pre><code class="ruby">\015\012clients.each { |c| puts c.name }\015\012\015\012find_tag("subtle")\015\012</code></pre>\015\012\015\012Every [[hooks|hook]] except the *create hook* will be run before the event is actually processed and the return value of the supplied proc will determine if processing continues or not. A return value of *false* will effectively stop processing of the event.\015\012\015\012Following [[hooks]] exist so far:\015\012\015\012{{>toc}}\015\012\015\012h2.
