[erlang-questions] Erlang-based opensource publish-subscribe servers

[Ulf Wiger]

Hi Zvi,

One way to implement publish/subscribe is with gproc properties.


-define(KEY, {?MODULE, subscr}).

subscribe() ->
    gproc:add_local_property(?KEY, undefined).

publish(Event) ->
    [P ! {self(), ?KEY, Event} || {P,_} <- gproc:lookup_local_properties(?KEY)].


Gproc takes care of monitoring the subscribers. Change local to global
for global publish/subscribe.
