Hi all,
If the function executed in a future throws an error it is printed out in
the repl immediately. If that function is executed in a future which
itself is executed in a future then it isn't.
For example, imagine somebody wrote the following code (please, suspend
belief and just accept p
Hi,
I am trying to get clojure-test-mode working in emacs

I have the nrepl working great, the problem is if I C-c, C-, in a test file
then I get the

clojure.test.mode,
https://github.com/technomancy/clojure-mode/issues/146#issuecomment-15447065
provides one solution - navigate to the source code and then start nrepl.

Howdy,
I am using clojure.test and have some questions of how to write idiomatic

Hi all,
I am doing some (naive and trivial) performance tests before deciding
whether and how to use Clojure for some performance critical number
cruching and I wanted help understanding the behaviour.
I am defining an array inside a function, setting the contents to be 1 and
then summing them
l defs and then rerun your benchmarks.

Ah OK, I didn't realise. I thought the vars would be locally scoped, i.e.
semantically equivalent to 'let'ed symbols.

I would replace it with loop/recur or a while, with both checking a

An alternative approach would be core.async with a stop channel and then
use alt! to check them both simultaneously.

Isn't this exactly what defrecord does?

I know this is a different direction than a lot of people but I store
everything in the app-state and so far it has worked well. There are a
hundred reasons why this (storing everything in app-state) is a
terrible idea, but I haven't run into any of them.
The main driver for this was for bug repor
You could build something on top memory mapped files. I did this to solve
similar requirements with good effect.

What I really want to do is have ReusableComponent be a component in a
system so it can pull its external collaborators. However,

Hi,
I am wiring up a bunch of CRUD command handlers for different aggregates
using prismatic schema to validate and it is screaming out for a macro, but
my ignorance is screaming even louder :).
The form I want to emit is something like (for a 'Location' for example):
(s/defn ^:always-validate
is defined in.
Any ideas?

Thanks Tobias. The complete macro body is now:
(let [{:keys [hierarchy-key
cascade-keys
define-command-schema
defined-event-schema
define-command-key
defined-event-key]} (default-options aggregate)]
`(do
