Mork compiler tool

Mork is a compiler tool with XML support. You specify some syntax (either by a traditional grammar or by a DTD) and Mork generates the appropriate parser. Mork is implemented in Java and generates Java class files.

Features

• Mapping A specification file simply associates grammar symbols with Java classes. Mork generates a mapper that instantiates these classes from any input streams of the given syntax. A mapper is like an ObjectInputStream with a user-defined syntax.

• Scanner Unicode support, scanner modes and quite a few regular expression operators. This XML grammar demonstrates almost every feature (scroll down to the scanner section).

• Parser LALR(1) parsers and regular expression operators like ?, * and +. This Java grammar demonstrates most of them.

• Attribution Well-defined attribute grammars: Any number of synthesized and inherited attributes. Access to non-local attributes.

• Examples Mork includes various non-trivial examples. (1) An interpreter with flow-control statements and support for several data types. (2) A compiler that generates Java bytecode.

• XML support (experimental!) Given a DTD file, Mork generates a validating XML parser. This parser supports both general and parameter entities. Example.. Unsuppored: namespaces, any elements, all elements.
