A convenient way to work with websocket data streams
A convenient way to work with information streaming from websockets, built on top of the Python iterator protocol.
When subscribing to a stream of qualified data I am usually interested in either the latest value i.e. the one I want when I am ready to do something with it or all the values since I last checked.
whereismysock also has a most subscriber which is all with an upper bound to the number of messages it keeps in memory (deleting the eldest first).
>>> from whereismysock import latest >>> usdjpy = latest("ws://toplevel/USDJPY") >>> next(usdjpy) ...>>> from whereismysock import all >>> nk225 = all("ws://trades/NK225") >>> next(nk225) ...
I like it because it makes “synchronising” different source of information super easy.
>>> hhi = latest("ws://toplevel/HHI") >>> hsi = latest("ws://toplevel/HSI") >>> next(zip(hhi, hsi)) ...
