Example #1

File: ExtractInterfaceTool.py Project: pcmarks/Jython-ANTLR4-Book-Examples

def main():
    ais = ANTLRFileStream(sys.argv[1])
    lexer = JavaLexer(ais)
    tokens = CommonTokenStream(lexer)
    parser = JavaParser(tokens);
    tree = parser.compilationUnit()

    walker = ParseTreeWalker()
    extractor = ExtractInterfaceListener(parser)
    walker.walk(extractor, tree)

Example #2

def main():
    ais = ANTLRFileStream(sys.argv[1])
    lexer = JavaLexer(ais)
    tokens = CommonTokenStream(lexer)
    parser = JavaParser(tokens)
    tree = parser.compilationUnit()
    walker = ParseTreeWalker()
    extractor = InsertSerialIDListener(tokens)
    walker.walk(extractor, tree)
    print extractor.rewriter.getText()

Example #3

def main():
    ais = ANTLRFileStream(sys.argv[1])
    lexer = JavaLexer(ais)
    tokens = CommonTokenStream(lexer)
    parser = JavaParser(tokens)
    tree = parser.compilationUnit()

    walker = ParseTreeWalker()
    extractor = ExtractInterfaceListener(parser)
    walker.walk(extractor, tree)
