module OutputSafetyHelper
# This method outputs without escaping a string. Since escaping tags is
# now default, this can be used when you don't want Rails to automatically
# escape tags. This is not recommended if the data is coming from the user's
# input.
#
# For example:
#
# <%=raw @user.name %>
def raw(stringish)
stringish.to_s.html_safe
end
# This method returns a html safe string similar to what <tt>Array#join</tt>
# would return. All items in the array, including the supplied separator, are
# html escaped unless they are html safe, and the returned string is marked
# as html safe.
#
# safe_join(["<p>foo</p>".html_safe, "<p>bar</p>"], "<br />")
# # => "<p>foo</p>&lt;br /&gt;&lt;p&gt;bar&lt;/p&gt;"
#
# safe_join(["<p>foo</p>".html_safe, "<p>bar</p>".html_safe], "<br />".html_safe)
# # => "<p>foo</p><br /><p>bar</p>"
