ExtendJ - The JastAdd Extensible Java CompilerExtendJ, formerly JastAddJ, is an extensible Java compiler built using the declarative attribute grammar system JastAdd. Notable features:
ExtendJ is useful if you are looking to develop static analyses for Java, or if you want to prototype new Java language features. Getting StartedWe have some useful material for new extension developers on the Getting Started page. If you just want a quick introduction, please take a look at these slides. DevelopmentBy fixing bugs and refactoring ExtendJ we risk breaking extension compatibility. Please keep this in mind if you plan on building an extension. We recommended that you base your extension on a specific commit of ExtendJ and upgrade only if you have good test coverage that can ensure your extension keeps working. Java CompatibilityExtendJ supports Java 5-11 with varying levels of compliance. The Java 8 support is close to feature complete with some known type inference problems. Java 9 through 11 support is available but not thoroughly tested. We work toward improving Java compatibility by finding and fixing bugs. This requires a lot of testing, and we are very thankful for any compatibility issues that you report. Please look at the compiance issues page for more information. If you encounter a Java compliance error, please report it to our issue tracker. To test compatibility we use continuous integration to compile and test Open Source projects with ExtendJ. Currently each commit of ExtendJ is tested on Ant 1.9.9, Antlr 4.7.1, JaCoP 4.0.0, and JUnit 4.12. Development HistoryExtendJ was originally created by Torbjörn Ekman at Lund University. Improvements have been made by several contributors over the years:
