module Haml::Filters::Ruby

Parses the filtered text with the normal Ruby interpreter. Creates an IO object named ‘haml_io`, anything written to it is output into the Haml document. In previous version this filter redirected any output to `$stdout` to the Haml document, this was not threadsafe and has been removed, you should use `haml_io` instead.

Not available if the {file: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.
