summary

ExtendJ is an extensible Java compiler built with Attribute Grammars and generated by JastAdd; it evaluates attributes on the AST so execution order is automatic and small computations compose into extensions. The repo adds Java 7 then Java 8 as extensions, students produce working extensions in about three weeks, demos include a string-equality static check, an attempted spread-operator parser, and a working multiplicities extension that compiles and runs. Extensions generate Java code and integrate into the compiler without pass-order juggling.
