aatree release 0.4.0--Durable Applications, Further Decoupling
The aatree project provides fully compatible alternatives to Clojure sorted-map, sorted-set and vector, with several extensions: - AAVector supports add/drop at any point using addn and dropn. - AAMap and AASet implement Reversible, Counted, Indexed and Sorted - CountedSequence implements Counted and do not use synchronized. - Lazy deserialization/reserialization provides ridiculously fast deserialize/update/reserialize processing typical of disk access. Release 0.4.0: - Functions have been added for file load/save using nio FileChannel, and for a 256-bit checksum. Examples have also been included showing how to use these functions in an application. - The API has been reworked to decouple application code from the choice of implementation for the data structures. (The old API has been deprecated.) https://github.com/laforge49/aatree#readme On Clojars: https://clojars.org/aatree -- You received this message because you are subscribed to the Google Groups "Clojure" group.

State Change Listener in Clojure on a Database
Hi all, I'm new to Clojure and I've been exploring the possibility of using it to handle a large list of Users stored in a Postgresql Database. I can see that there are some great sql libraries for clojure to query a Postgresql database and this is fine. However, I was wondering if there are any useful Clojure features or libraries that could allow me to 'listen' for changes to a Users Table in the Database. A use case scenario to describe what I want would be as follows: Say someone registers their details on a website and their details are persisted to the Database. I then want some process to pick up that a new user is now in the database and send this user information to a client that has registered to listen for new users. Is something like this possible in Clojure where it can handle listening to state changes and trigger a notification? Thanks in advance to anyone who chimes in with advice, Regards, Adrian. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: clojure.repl/doc - change request - print vs return-value
I am making a namespace inspector (using JavaFX) (somewhat like the Swing-based tree-inspector in Clojure), and when getting a function, I would like to diplay the same meta-information as "doc" prints in the REPL - including the special forms data coded in a private var/map in Clojure.

Re: aatree release 0.4.0--Durable Applications, Further Decoupling
I've added the following qualifier to the README for this project, just to clarify that some of the code is more illustrative than practical: It is not often that you need lazy deserialization when doing a file load. Rather, we are using file load and save here to illustrate how to use the lazy structures of aatree. (A better use of these structures would be in implementing a database, of course. But that will not be covered for a release or three.)

Re: lazyseq?
I’ll second what Timothy Baldridge wrote. By the way, you have to make sure you’re dealing with some sort of clojure.lang.IPending before you call realized? on it. I prefer to test against interfaces rather than concrete classes so I would try something like this (minimally tested): (defn lazy-seq? [x] (and (instance? clojure.lang.IPending x) (seq? x) (not (realized? x Even after a lazy seq has been “realized” (typically with doall), it’s still a clojure.lang.LazySeq but the results have been cached so it’s not so “lazy” anymore.
