Python Interpreter.call_stack Examples

Example #1

    def makeInterpreter(self, text):
        from spi import Lexer, Parser, SemanticAnalyzer, Interpreter
        lexer = Lexer(text)
        parser = Parser(lexer)
        tree = parser.parse()

        semantic_analyzer = SemanticAnalyzer()
        semantic_analyzer.visit(tree)

        interpreter = Interpreter(tree)
        interpreter.call_stack = TestCallStack()
        return interpreter

Example #2

def interpreter(text):

    lexer = Lexer(text)
    try:
        parser = Parser(lexer)
        tree = parser.parse()
    except (LexerError, ParserError) as e:
        return (None, e.message)

    semantic_analyzer = SemanticAnalyzer()
    try:
        semantic_analyzer.visit(tree)
    except SemanticError as e:
        return (None, e.message)

    interpreter = Interpreter(tree)
    interpreter.call_stack = TestCallStack()
    return interpreter
