Sawyer::Document::Markup::Eval Class Reference


Evaluate arguments a second time.

All arguments are evaluated once (like for normal functions) and are concatenated. The concatenation is then evaluated recursively and its result becomes the result of this function. Escaped characters in the concatenation are unescaped before it is evaluated.
