Hi Andy,
I would provide a function that wraps put!. It would still return a
deferred, but not the result of put!. It would create a deferred,
representing the result of the computation and pass it down the stream
together with the input. Consumers would set its value once the computation
is done.
Hey All,
I'm trying to build a library that exposes manifold streams for data
producing applications. The intention
would be for these apps to s/put! to a sink stream returned by the producer
function. However, I need to
take the value that is put in and pipe it into some other function before I
PersistentArrayMap is automatically promoted to PersistentHashMap when it
reaches a specific size. This is done for performance reasons. Neither
collection is considered ordered, and you should use a different datatype
if you want ordered data.

array-map preserving order is a property of its implementation, but not a
promise to those who use them.
Adding a key/value pair to an array-map that takes it over a certain
threshold size changes its implementation to a hash-map, which in general
changes the seq order completely. This is by desi
This works well as expected. The order of input elements is maintained.
(into (array-map) [[1 :a] [2 :b] [3 :c] [4 :d] [5 :e] [6 :f] [7 :g] [8 :h]])
; => {1 :a, 2 :b, 3 :c, 4 :d, 5 :e, 6 :f, 7 :g, 8 :h}
However, as soon as the number of the input elements exceeds 9, the order
is not maintained a
To do my bit to spread the Clojure meme, I've put together the essence of
the finest resources in print that have helped me grok Clojure. I take a
look at the following (Clojure, and related) books, in turn:

Okay, I am an idiot. I had the "directory watch" setup to watch the
directory where the uberjar was built, so of course it was triggered
thousands of time while the uberjar was built, since I guess every new byte
added to the uberjar triggers the change event.
So I set my app to listen on the
I've done a lot with AA trees in the past, creating variations that are
immutable, durable (replacing b-trees) and versioned of vectors, maps and
sets.
I would like to migrate these ideas from Java to Clojure, while
implementing the interfaces appropriate for Clojure.
Still being very much a n
Agent2 release 0.2.1 now wraps exceptions passed as values in a vector
marked with the metadata flag :wrapped. The request-call method can now
distinguish between exceptions thrown by a request (and rethrows them) and
exceptions used as responses (and unwraps them before returning
them). https:
Let's assume for a moment that, for some strange reason, the "directory
watching" strategy won't work here. Does anyone have any other suggestions?
I am thinking there must be a simple way to setup Jenkins and Supervisord
to run these apps, but what I'm doing keeps getting more and more complex
Reid, thank you. I think you answer half the question. You make a good
point about giving the JVM a way to better optimize a hot path. I think you
are right about that. But, given the large amount of repetition between
"chain'-" and "chain-" I'm wondering why this wasn't done with a macro?
Oh, and whether or not Java regular expressions let you specify ranges of
such characters outside the BMP, I have no idea. I would expect there to
be odd behavior in that area of Java's regular expression implementation,
but haven't done extensive testing myself to find out. I would recommend

Java uses UTF-16 encoding in memory for String objects. Characters in the
