#format_args(format = lambda{|a| a}, &proc) ⇒ Object

Formats the matched arguments of the associated Step. This method is usually called from visitors, which render output.

The format can either be a String or a Proc.

If it is a String it should be a format string according to Kernel#sprinf, for example:

'<span class="param">%s</span></tt>'

If it is a Proc, it should take one argument and return the formatted argument, for example:

lambda { |param| "[#{param}]" }
