And one more, for JavaCC:


https://javacc.dev.java.net/servlets/ProjectDocumentList?folderID=110&expandFolder=110&folderID=0


These are JavaCC grammars, but you can convert them to JJTree grammars
(which produce an AST) by just renaming them to C.jjt and twiddling the
start symbol to return the root AST node.
