Module | Haml::Filters::Ruby |
In: |
lib/haml/filters.rb

Parses the filtered text with the normal Ruby interpreter. All output sent to `$stdout`, such as with `puts`, is output into the Haml document. Not available if the {file:HAML_REFERENCE.md#suppress_eval-option `:suppress_eval`} option is set to true. The Ruby code is evaluated in the same context as the Haml template.
