In order to inject metadata into your source, you can use the insert_metadata
operator.
You enable it by adding in your script:
radio = insert_metadata(id="radio", radio)
That way, the radio source is redefined with the possibility to inject
metadata.
When running the script with the telnet server enabled:
set("server.telnet", true)
you should be able to connect to the port 1234 on the localhost:
telnet localhost 1234
This should open a console where you can type commands. For instance "help"
will return the list of available commands. Also, some commands are self-
documented, so you can ask for their documentation.
In your case, you can then insert metadata, for instance:
radio.insert title="foo",artist="bar"
For advanced usages, you can also execute this command within the script it
self, using the server.execute operator:
server.execute('radio.insert title="foo",artist="bar"')
This operator returns the strings corresponding to the output of the command.
Usually you don't care about them and you ignore the output:
ignore(server.execute('radio.insert title="foo",artist="bar"'))
