Hello everybody,
I had previously seen a conversation where some body had a macro where they
would give a name to the intermediate values .. I am not able find it via
google .. can some body help me here?
The problem is
(-> x f g) being re-written as (g (f x)) I can't refer to intermediate
value
Hi,
a quick'n'works-now way is:

((fn [x] (do-stuff-with x (refering-twice x
(xyz fgh))
Or: (#(do-stuff-with % (refering-twice %)))

Hi,
the ~ in front of first is too much, because first is not in a syntax-quote.
Also I wouldn't capture var because it is special form.
(defmacro bound->
[fst & more]
(if (seq more)
`(let [~'v ~fst]
(bound-> ~@more))
fst))
Sincerely
Meikel

G'day all,
Thanks Miki for fs, also coming from a Python background I am enjoying
the familiarity!
The thing that I most often use tempdir for is unit testing where I

Hi,
can anybody recommend a way to integrate clojuresque (1.4.1) with SLIME? I did
some googling but couldn't find any helpful pointers.

Thanks a lot for getting me started! I had to tweak it a little, but

You could use identity as a predicate to filter:
user=> (def s [nil nil 1 2 3])
#'user/s
user=> (first (filter identity s))

Yeap, that makes more sense, after all the change was on m. Maybe the
error message could read "h must receive matching primitive."

Cool, I'll clean up the code and submit it along with tests and docs. While
Im about it i may as well write the equivalent macro for tempfile.

Or:
(find-first (complement nil?) coll)
or:
(first (filter (complement nil?) coll))
but I like Meikel's (first (keep identity coll)) suggestion, even if I
find it less straight-forward.

The architecture of a large system should designed independent of the
language in which you're working You should strive to identify the
architecture styles you need for your problem domain, and then
intelligently compose them with connectors that help fulfill your
nonfunctional requirements/guara
IMHO, CQRS and CEP are identical at conceptual level, but they have been
established by people having different backgrounds, thus cooking up
different vocabulary for these practices. Practitioners tend stress
different aspects of the system but essentially they're rather trying to
solve same class
I was looking at
http://saucelabs.com/blog/index.php/2009/12/running-your-selenium-tests-in-parallel-clojure/
and in the comments, :Scott suggested that a macro could reduce some
of the boilerplate that you see here:
(def test-google
{
:name "google"
:test (fn [client]
(doto cl
"client" is a qualified name.
So either use "client#", but you don't want that since the macro should be
anaphoric.
The other option, which you're close to, is using "~'client", which
essentially makes "client" 'unqualified'.
