[erlang-questions] Beginner Question: Spring-like IOC in erlang
Wed Apr 13 21:44:23 CEST 2011
1. Is there an idiomatic way to use dependency injection in erlang?
Most of my use of Spring DI has been to facilitate injection of test
classes into a stack for functional testing. Is this sort of thing done
2. How about AOP style join-points for before and after execution around
As an example, wouldn't it be cool to dynamically enable debug or trace
level logging for an application when a certain error threshold is
reached? Then, when the system returns to a normal state, the error
logging could be turned back down... I think I might start doing this in
the Java stacks I'm currently working with (log4j).
3. Is there a way to intercept messages to a process? This is the real
question... Say a process dies unexpectedly and OTP restarts it... it
would be cool to be able to dynamically proxy messages to a process that
has exceeded some error threshold. The proxy could log them, or perform
more intensive error analysis... Then, once the system is back in a
normal state, the proxy could be removed from the message loop chain.
