I recently ran into this problem again.
The solution I came up with is:
(defn filter-printable [obj]
(cond
(or (symbol? obj) (number? obj) (string? obj) (keyword? obj)) obj
(vector? obj) (apply vector (map filter-printable obj))
(seq? obj) (map filter-printable obj)
(set? obj)
Shouldn't that be:
(defn filter-printable [obj]
(cond
(or (symbol? obj) (number? obj) (string? obj) (keyword? obj)) obj
(vector? obj) (apply vector (map filter-printable obj))
(seq? obj) (map filter-printable obj)
(set? obj) (into #{} (map filter-printable obj))
(map? obj) (into
## Context:
I'm doing some communication across cljs/clj with core.async
## Problem:
I want a certain function called whenever:
(a) the first time the channel is closed
(b) when the channel is gc-ed (if not previously closed)
(a) is rather easy: I define my own channel, wrapped
Hi folks, sorry I'm a bit late to the party, but Chord might be a good base for
what you want to do? It probably falls a bit short at the moment on your
disconnection semantics, but could be worth a shot.

(b) is easy if you're willing to drop down to Java, or use gen-class. You
can define a finalize method.
On the other hand, you might also want to look into WeakReference and
ReferenceQueue, which can be used from Clojure with interop. You can
discover when objects become eligible for GC with
Hi Mimmo
Thank you for this tutorial - I managed to follow along and experience the same
live coding with emacs/cider - really nice to see how all the components work
together and drive the browser from the browser-repl in emacs.
Kind regards

I added a better sample with a UINavigationController and a small uikit
framework(very very alpha).

Feedback and improvements on the uikit framework are very much welcome.

Hi,
I have a config file that contains a Clojure map. If I slurp that file it
obviously returns a string.
Is it possible to return that read file as a map (its original data
structure) and not a string?
Thanks

Hello, all,
I have just started using core.async, and I was curious as to why
particular sequence functions where chosen to be implemented. For
example, there is take, but no take-while or drop. Is this a deliberate
design decision?
Thanks for the great library!
Sincerely,
Daniel

I can't speak for the core.async implementers, of course, but I've been
working on a similar library for Javascript, and had to realised that not
all sequence operations make sense, or are even possible in the context of
channels.
The one you mentioned, take-while, is a good example. Once

get Cider. According to package-list-packages, I am using cider
