Thanks for the suggestions, I have created a wrapper function and it
works, but it seems, there are more problems.
I use reader/read-string function to parse clojure data structures
sent as POST messages, and it doesn't recognize keywords in IE.
For example, it treats {:status :ok} as {"\uFFFD'sta
I just have tried to replace all special characters in core.js to
their escaped equivalents (\uFDD0 for keywords) and it works fine.
But I still not certain where this bug comes from.

Is there a way to pretty-print an object with its metadata?
If I (set! *print-meta* true) at the REPL, I can see the metadata. If I
use (pprint thing), I can see the structure much more easily. How can I do
both?

how about something like this?

Hi,
I don't know a built-in way. But that doesn't mean, that there isn't one.
You could ask Tom Faulhaber directly. He did the pretty print stuff.

By looking at pprint.clj, I have come up with something that seems to work.
No "hacking" is necessary - the code in pprint is impressively clear and
extensible. It's obviously designed to allow exactly this sort of
extension to the printing mechanism.

Interning a string is caching it in a string pool that lives in the jvm's
permgen space. Calling .intern() on a string either adds it to the pool or
return the string object that's already in the pool. This is safe to do
for strings that are defined statically, generally you don't want to

I find the idea of using a special filename extension rather
appealing. A couple of notes:
(1) I'm not sure there is a "generic clojure". ClojureScript has a
couple serious differences from Clojure, such as the way macros are
included in (ns ...).
(2) ClojureScript macro files, AFAICT, really a

Seriously though, start with viper-mode.

Hi,
I think your problem is more general than just Clojure. Actually there
was a long
discussion on the "Functional Programming" group over at LinkedIn
about applying
UML to functional languages.
The general consensus is that you can somehow adapt UML concepts to
describe
data structures and exec

Sorry if I'm drifting a bit off topic, but I just wanted to point out that it's
convenient to use just the function name if the arguments are already in the
appropriate order.
But I don't see any reason why this would be faster than (dorun (map
side-effect-fn s1 s2 s3)). You're creating and then dismantling a
three-element vector at every iteration to no purpose.

Looks like this is an active project, and something to keep an eye on:

Yeah, but it won't quite work if even the metadata has metadata.

Good catch! I was about to add this to my personal toolkit of "generally
useful random crap" (every programmer has one of those, right?). I'll make
sure to cover that edge-case. Thanks.

Hi David,
Setting aside the "data binding" aspect of the problem for a minute..
jQuery, Dojo and other JS libs seem to be going all-in on the "event

The idea is: instead of binding event handlers to each individual
instance, you let the events bubble up to the top of the do

I've been trying to write a macro to generate predicates from maps,
for instance the map {1 :one 2 :two} would define two predicates, one?
and two? Here's the first part of the macro:
(defmacro make-predicate [keyword-pair]
`(defn ~(symbol (str (name (nth (eval keyword-pair) 1)) "?")) [~'x]
It shouldn't, obviously. It appears to be holding on to a compile-
time value somewhere. I'll track it down this weekend.

Thank you, that works great! It's a nice use of destructuring too,
which I should of thought of.
I guess this is one case where solving the problem in pieces does not

macros over sequences. I understand a little more now why.
