Re: Message to Var - modify different variables using one ZMQ Sub Message Source

[Bogdan Reshetnikov]

UPD: Works great!

----------

class blk(gr.basic_block):
    def __init__(self):
        gr.sync_block.__init__(
            self,
            name='Message Pair Multiplexer',
            in_sig=None,
            out_sig=None
        )

        self.message_port_register_in(pmt.intern('msg_in'))
        self.set_msg_handler(pmt.intern('msg_in'), self.handle_msg)

        self.variables = [
            'amp',
            'freq',
            'test',
            'whatever',
        ]
        for var in self.variables:
            self.message_port_register_out(pmt.intern(var))

    def handle_msg(self, msg):
        # i rewrote this line from memory so might have messed up whoops
        if pmt.serialize_str(pmt.car(msg)) in self.variables:
            self.message_port_pub(pmt.car(msg), msg)

    def work(self, input_items, output_items):
        pass

hope this post will help other beginners like me in the future.
