Projects / Polyglot


Polyglot is a highly extensible compiler front end for the Java programming language. Using Polyglot, language extensions can be implemented without duplicating code from the framework itself. Polyglot has been used to implement domain-specific languages, to explore language design ideas, to simplify Java for pedagogical purposes, and for various code transformations such as optimization and fault injection. Polyglot has been used for both major and minor language extensions.

    Release Notes: The dataflow framework was changed to add functionality. CFGs now have two nodes per term, one representing the "entry" into that term, another the "exit". Extensions will have to be updated to work with this new framework. See doc/DATAFLOW_2_0.txt for a more detailed explanation of the changes. Miscellaneous bugs were fixed.

Miscellaneous bugs were fixed.
