With a very clear and simple syntax, +you can write an attributed grammar that is translated into a recursive +descendant parser. TPG generated code is very closed to the original +grammar. This means that the parser works "like" the grammar. A grammar rule +can be seen as a method of the parser class, symbols as method calls, +attributes as method parameters and semantic values as return values. You +can also add Python code directly into grammar rules and build abstract +syntax trees while parsing. + +The first application of TPG is TPG itself. The first (not released) version +of TPG has been written by hand then was used to generate next versions. Now +TPG can generate itself. |
