I'm having to do some interop with a proprietary - and erroneously
documented - Java SDK. There's a class C with a method described as
'translate(java.lang.String). Trying to call the method with a Clojure on
an object of class C I got a 'no matching method found' error.
So I used the following
It looks very similar to the pattern I was trying to avoid in the first
place. I've also got the problem of multiple threads (and its been pointed
out that my original solution was not thread safe). In my experience bugs
of an 'extremely rare but could conceivably happen' nature are the sort of
I'm somewhat late to the party, but what the hey - it's a quiet Sunday
afternoon, and for my own amusement I came up with:
(defn spaces [n] (apply str (take n (repeat .
(defn n-a [n] (char (+ n (int \A
(defn a-n [a] (- (int a) (int \A)))
(defn gap [n] (spaces (dec (* 2 n
(defn
Thanks to everyone for the responses. I was completely unaware of
core.memoize although I think there is a very convincing case for delay; I
certainly accept the thread safety problem with the existing code. Action
this day on that one!
I'm inclined to go down the @@ syntactic route, simply in
strictly once
but also (atom) allow for changing the underlying value (i.e. clear the
cache).

Looking through my recent work I see that a number of atoms, swap! and
reset! calls have snuck into my work, usually when there's an expensive
operation like reading and parsing a large file or connecting to a
database. I find I'm doing things like
(def conf (atom nil))
(defn config []

positive side, I'm now in a position to add a useful example to the
grimoire.

I've recently been serialising some data using Edn, and to date this has
caused no problems. During some tests today, I serialised a string
representing a file path that originated on a windows machine \My
Documents\somedoc.txt. Edn throws a runtime exception when reading this
back claiming:

I've got a working knowledge of Clojure and I'm trying to extend my reach
into Clojurescript, om, and bootstrap as I want the resulting website to
look reasonable.
I've worked my way through the om tutorials and I have a simple plain om
example of my own which doesn't use bootstrap.
