haml_tag('.bar') #=>

haml_tag('span#foo.bar') #=> ``` ```ruby haml_tag('span#foo.bar', :class => 'abc') #=> ``` ```ruby haml_tag('span#foo.bar', :id => 'abc') #=> ``` -------------------------------- ### HTML-Style Attribute Syntax Source: https://haml.info/docs/yardoc/file.CHANGELOG.html Introduces HTML-style attribute syntax for Haml, offering a more concise and language-agnostic approach compared to Ruby's hash-style syntax. ```haml %a(href="https://haml.info" title="Haml's so cool!") %img(src="/images/haml.png" alt="Haml") ``` -------------------------------- ### Compile Haml::Helpers for Tilt Templates Source: https://haml.info/docs/yardoc/Haml/TemplateExtension.html Activates Haml::Helpers for tilt templates. This method is used to extend the template with Haml's helper methods. ```ruby def compile(*) "extend Haml::Helpers; #{super}" end ``` -------------------------------- ### Haml Equivalent of Merged Attributes Source: https://haml.info/docs/yardoc/file.REFERENCE.html Shows the equivalent Haml syntax for merging class and ID shortcuts with long-hand attributes. ```haml %div{:id => ['Article', @article.number], :class => ['article', 'entry', @article.visibility]} Gabba Hey ``` -------------------------------- ### Haml Recursive Data Attributes Source: https://haml.info/docs/yardoc/file.REFERENCE.html Demonstrates Haml's recursive expansion of nested data attribute hashes. ```haml .book-info{:data => {:book => {:id => 123, :genre => 'programming'}, :category => 7}} ``` -------------------------------- ### Compiling a Rails Template with Haml Source: https://haml.info/docs/yardoc/Haml/RailsTemplate.html Compiles a given Rails template using Haml. It retrieves template source, merges options based on template type (e.g., XML/XHTML), and applies annotations if enabled. Finally, it instantiates and calls the Haml::Engine. ```ruby # File 'lib/haml/rails_template.rb', line 26 def call(template, source = nil) source ||= template.source options = RailsTemplate.options # Make the filename available in parser etc. if template.respond_to?(:identifier) options = options.merge(filename: template.identifier) end # https://github.com/haml/haml/blob/4.0.7/lib/haml/template/plugin.rb#L19-L20 # https://github.com/haml/haml/blob/4.0.7/lib/haml/options.rb#L228 if template.respond_to?(:type) && template.type == 'text/xml' options = options.merge(format: :xhtml) end if ActionView::Base.try(:annotate_rendered_view_with_filenames) && template.format == :html options = options.merge( preamble: "\n", postamble: "\n", ) end Engine.new(options).call(source) end ``` -------------------------------- ### Autoclosing Tags Option Source: https://haml.info/docs/yardoc/file.CHANGELOG.html The Haml executable now accepts an `--autoclose` option to specify tags that should be autoclosed. ```bash haml --autoclose a,img,li,input,link,meta,br,hr ``` -------------------------------- ### Instantiate and Parse Attributes Source: https://haml.info/docs/yardoc/Haml/AttributeParser.html A convenience class method to create a new instance of AttributeParser and immediately call its parse method with the provided text. ```ruby def self.parse(text) self.new.parse(text) end ``` -------------------------------- ### Customizing Object Reference with `haml_object_ref` Source: https://haml.info/docs/yardoc/file.REFERENCE.html Demonstrates how to customize the class name used in object references by implementing the `haml_object_ref` method on the Ruby object. ```ruby # file: app/models/crazy_user.rb class CrazyUser < ActiveRecord::Base def haml_object_ref "a_crazy_user" end end ``` ```haml #- file: app/views/users/show.haml %div[@user] Hello! ``` -------------------------------- ### Array Attributes for :class and :id Source: https://haml.info/docs/yardoc/file.CHANGELOG.html Demonstrates how Haml handles Ruby arrays for :class and :id attributes, including flattening and truthiness checks. ```Haml .column{:class => [@item.type, @item == @sortcol && [:sort, @sortdir]] } ``` ```HTML class="column numeric sort ascending" class="column numeric" class="column sort descending" class="column" ``` ```Haml .item{:class => @item.is_empty? && "empty"} ``` ```HTML class="item" class="item empty" ``` -------------------------------- ### Haml Merging Class/ID Shortcuts with Long-hand Attributes Source: https://haml.info/docs/yardoc/file.REFERENCE.html Illustrates how Haml merges class and ID shortcuts with explicit long-hand attributes. ```haml %div#Article.article.entry{:id => @article.number, :class => @article.visibility} ``` -------------------------------- ### HTML5 Custom Data Attributes Source: https://haml.info/docs/yardoc/file.CHANGELOG.html Shows how to generate HTML5 custom data attributes using a :data hash in Haml. ```Haml %div{:data => {:author_id => 123, :post_id => 234}} ``` ```HTML

``` -------------------------------- ### compile Source: https://haml.info/docs/yardoc/Haml/Compiler/SilentScriptCompiler.html Compiles a silent script node. If the node has no children, it compiles the node's text directly. Otherwise, it compiles the node with its children. ```APIDOC ## compile(node, &block) ### Description Compiles a silent script node. If the node has no children, it compiles the node's text directly. Otherwise, it compiles the node with its children. ### Method `compile` ### Parameters * **node**: The node to compile. * **block**: A block to be executed during compilation. ### Returns A multi-element array representing the compiled code, including the script text and newlines, or a compiled representation of the node and its children. ``` -------------------------------- ### Haml CLI: Method Missing Source: https://haml.info/docs/yardoc/Haml/CLI.html Handles dynamic method calls, forwarding calls with more than one argument to the superclass and rendering single-argument calls. This provides flexibility for CLI commands. ```ruby def method_missing(*args) return super(*args) if args.length > 1 render(args.first.to_s) end ``` -------------------------------- ### Class Name Merging and Ordering in Haml Source: https://haml.info/docs/yardoc/file.REFERENCE.html Illustrates how Haml merges and orders class names from different sources (tag identifiers, HTML attributes, Hash attributes). Note that older versions sorted alphabetically. ```haml .foo.moo{:class => ['bar', 'alpha']}(class='baz') ``` -------------------------------- ### Compile Less CSS in Haml Source: https://haml.info/docs/yardoc/Haml/Filters/Less.html This method compiles Less CSS content within a Haml node. It requires the 'tilt/less' library and formats the output within a '] temple end ``` -------------------------------- ### Compiled HTML for Combined Object Reference and Class Source: https://haml.info/docs/yardoc/file.REFERENCE.html The HTML output when an object reference is combined with an explicit `:class` attribute, demonstrating the merged class names. ```html

``` -------------------------------- ### Initialize Haml::Identity Source: https://haml.info/docs/yardoc/Haml/Identity.html Constructs a new instance of Haml::Identity, initializing the unique ID counter to 0. ```ruby def initialize @unique_id = 0 end ``` -------------------------------- ### Render Filtered Content with Tilt Source: https://haml.info/docs/yardoc/Haml/Filters/TiltBase.html This class method renders content using a Tilt template. It handles indentation for the output. Use this when you need to process source code through a Tilt-compatible engine within Haml. ```ruby def self.render(name, source, indent_width: 0) text = ::Tilt["t.#{name}"].new { source }.render return text if indent_width == 0 if text.frozen? text.gsub(/^/, ' ' * indent_width) else text.gsub!(/^/, ' ' * indent_width) end end ```
