Class: PageTemplate::ValueCommand

ValueCommand will print out a variable name, possibly passing its value through a preprocessor.

% var variable [:processor: %]

variable is first plucked out of the Namespace,

The to_s of the output from Namespace#get is passed through parser‘s preprocessor. If :processor is defined, then parser.preprocessor.send(:processor,body) is called. This allows the designer to choose a particular format for the output. If :processor is not given, then parser‘s default processor is used.

Methods
