Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth_name, *attribs, &block) ⇒ Object

# File 'lib/aurita-gui/html.rb', line 358

def method_missing(meth_name, *attribs, &block)
  render(meth_name, *attribs, &block) 
end

Instance Method Details

#br ⇒ Object

Statically defined as <br /> must not have any attributes.

def br
  @output_buffer << '<br />'
end

#p(*attribs, &block) ⇒ Object

p is defined in Kernel, so we have to redirect it manually (method_missing won’t be triggered for it)

def p(*attribs, &block)
