cycle(first_value, *values) Instance Public methods 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 :name key will create a named cycle.

current_cycle(name = "default") Instance Public methods Returns the current cycle string after a cycle has been started. Useful for complex table highlighting or any other design need which requires the current cycle string in more than one place. # Alternate background colors @items = [1,2,3,4] <% @items.each do |item| %> <div style="background-color:<%= cycle("red","white","blue") %>"> <span style="background-color:<%= current_cycle %>"><%=

concat(string) Instance Public methods The preferred method of outputting text in your views is to use the <%= âtextâ %> 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. <% concat "hello" # is the equivalent of <%= "hello" %> if logged_in concat "Logged in!" else concat li

tag(name, options = nil, open = false, escape = true) Instance Public methods Returns an empty HTML tag of type name which by default is XHTML compliant.

content_tag(name, content_or_options_with_block = nil, options = nil, escape = true, &block) Instance Public methods Returns an HTML block tag of type name surrounding the content. Add HTML attributes by passing an attributes hash to options. Instead of passing the content as an argument, you can also use a block in which case, you pass your options as the second parameter.

cdata_section(content) Instance Public methods Returns a CDATA section with the given content. CDATA sections are used to escape blocks of text containing characters which would otherwise be recognized as markup. CDATA sections begin with the string <![CDATA[ and end with (and may not contain) the string ]]>. cdata_section("<hello world>") # => <![CDATA[<hello world>]]> cdata_section(File.read("hello_world.txt")) # => <![CDATA[<hello from a text

strip_tags(html) Instance Public methods Strips all HTML tags from the html, including comments. This uses the html-scanner tokenizer and so its HTML parsing ability is limited by that of html-scanner. strip_tags("Strip <i>these</i> tags!") # => Strip these tags! strip_tags("<b>Bold</b> no more! <a href='more.html'>See more here</a>...") # => Bold no more! See more here... strip_tags("<div id='top-bar'>Welcome to my website!</d
