module ActionView
module Helpers #:nodoc:
# The TextHelper module provides a set of methods for filtering, formatting
# and transforming strings, which can reduce the amount of inline Ruby code in
# your views. These helper methods extend ActionView making them callable
# within your template files.
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
# %>

# for a total length not exceeding <tt>:length</tt>.
#
# Pass a <tt>:separator</tt> to truncate +text+ at a natural break.
#
# ==== Examples
#
# truncate("Once upon a time in a world far far away")
# # => Once upon a time in a world...
#
# truncate("Once upon a time in a world far far away", :separator => ' ')
# # => Once upon a time in a world...
#
# truncate("Once upon a time in a world far far away", :length => 14)

# # => And they found t(clipped)
#
# truncate("And they found that many people were sleeping better.", :omission => "... (continued)", :length => 25)
# # => And they f... (continued)
#
# You can still use <tt>truncate</tt> with the old API that accepts the

# optional third parameter:
# truncate("Once upon a time in a world far far away", 14)

# Creates a Cycle object whose _to_s_ method cycles through elements of an
# array every time it is called. This can be used for example, to alternate
# classes for table rows. You can use named cycles to allow nesting in loops.
# Passing a Hash as the last parameter with a <tt>:name</tt> key will create a
# named cycle. The default name for a cycle without a +:name+ key is
# <tt>"default"</tt>. You can manually reset a cycle by calling reset_cycle
# and passing the name of the cycle. The current cycle string can be obtained
# anytime using the current_cycle method.
#
# ==== Examples
# # Alternate CSS classes for even and odd numbers...
# @items = [1,2,3,4]
# <table>
# <% @items.each do |item| %>
# <tr class="<%= cycle("even", "odd") -%>">
# <td>item</td>
# </tr>
# <% end %>
# </table>

#
# # Cycle CSS classes for rows, and text colors for values within each row
# @items = x = [{:first => 'Robert', :middle => 'Daniel', :last => 'James'},
