+ # The TextHelper module provides a set of methods for filtering, formatting
+ # and transforming strings, which can reduce the amount of inline Ruby code in

+ module TextHelper
+ # The preferred method of outputting text in your views is to use the
+ # <%= "text" %> eRuby syntax. The regular _puts_ and _print_ methods
+ # do not operate as expected in an eRuby code block. If you absolutely must
+ # output text within a non-output code block (i.e., <% %>), you can use the concat method.
+ #
+ # ==== Examples
+ # <%
+ # concat "hello"
+ # # is the equivalent of <%= "hello" %>
+ #
+ # if (logged_in == true):
+ # concat "Logged in!"
+ # else
+ # concat link_to('login', :action => login)
+ # end
+ # # will either display "Logged in!" or a login link
