Method: Arrow::Template#render

Defined in:
lib/arrow/template.rb

#render(nodes = nil, scope = nil, enclosing_template = nil) ⇒ Object Also known as: to_s

Render the template to text and return it as a String. If called with an Array of nodes, the template will render them instead of its own syntax_tree. If given a scope (a Module object), a Binding of its internal state it will be used as the context of evaluation for the render. If not specified, a new anonymous Module instance is created for the render. If a enclosing_template is given, make it available during rendering for variable-sharing, etc. Returns the results of each nodes’ render joined together with the default string separator (+$,+).
