I have been working with Clojure for a few months now. I am now more
familiar with it then I was even 3 months ago. I am now going back
through some of the early code I wrote, and I see a lot of redundancy
and mistakes. In particular, I notice this function that I wrote to
handle the request map (in a web app that is using Ring and
Compojure):
(defn process-event [request]
(let [request1 (process-pre-event-hooks request)
request2 (process-page-specific-pre-page-hooks request1)
request3 (process-mid-event-hooks request2)
request4 (process-page-specific-post-page-hooks request3)
request5 (process-post-event-hooks request4)]
request5))
I could probably re-write all of this as Ring middleware, yes?
Functions that take the request map, do something with it, and then
return the new, modified request map -- that is what middleware is,
yes? Or does middleware return a function that is then called on the
request map?
