Python PyFuncParser Examples

Example #1

File: pyfunc.py Project: gavioto/splunk-demo-opcda

def parse_func(pfunc):
    char_stream = antlr3.ANTLRStringStream(pfunc)
    lexer = PyFuncLexer(char_stream)
    tokens = antlr3.CommonTokenStream(lexer)
    tokens.fillBuffer()
    parser = PyFuncParser(tokens)
    return parser.pyfunc()

Example #2

File: pyfunc.py Project: linearregression/splunk-demo-opcda
