Atoms, reference to itself cause StackOverflowError
Hi all,
I noticed this behaviour that I was not expecting:

It is something expected or I should open a bug report ?

Re: Atoms, reference to itself cause StackOverflowError
Thank you :)
Extremely clear !

Hi Simone,
The stack overflow here is caused by the REPL trying to print a circular
reference. `swap!` always returns the new value of the Atom, and the REPL
tries to print it.
If you don't print the Atom, this self-reference can still work:
user= (def a (atom {}))
#'user/a
user= (do (swap! a assoc :self a) nil)
nil
user= (= a (:self @a))
true

Obtain name of interface from java file, regex + slurp doesn't works
Hi all,
I am trying to parse some java source file that contain the definition of
an interface, what I need is to get the name of the interface, what methods
it defines and what other interfaces it extend.
I used a regex (there is any clever way other than analyze the source ?)
that works pretty good, however it doesn't works all the time.
If I copy and paste the source test from the file to the repl it works
without any problem, however if I slurp the file it works only on some
files, not on every file.
What can be the problem ?
(defn is-interface? [str]
(re-matches #(.|\n)* interface (\w+) (.|\n|\{)* str))
is the regex I am using.
This:
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/ISeq.java
is a source that does NOT work.
This other:
https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/ILookup.java
is a source that DOES work.

Re: unusual question: how do you get morale?(or moral support)
I code only for myself, and honestly coding is what I like to do. I remember these days being in a very bad mood and all I wanted to do was to sit and code. I believe that what motivate myself is my own EGO, code for me is only about solving problem, and more problem I solve better my ego is. Anyway I am still a student and I don't have (m)any [I like that XP] financial issues. I am weird, but friends usually don't help me when I have an hard time, neither does my family (no that they wouldn't like to help me, they try most of the time but they simply don't work), time helps. For problems that I can not solve because they are not ups to me, I just don't think about, so I keep myself as busy as possible, until I don't feel great again. For problems that I can solve, well those are just other forms of coding, so I just fix that for my ego. :-) Someone else want to share ? On Sunday, May 12, 2013 9:34:22 PM UTC+2, atkaaz wrote: Hi. I've been meaning to ask (all of)you, how do you get moral support? How do you put yourself into that mood so that you're happy/willing to program? What motivates you to do it?

Re: ANN Quartzite 1.0 (final)

Re: Fund raiser for our projects
My point is that by the time that I am able to write a nice/useful article about any library a maintaners of the lib would be able to write 10 articles way better. Then still there if I write one article, you write another and @whoever write the next we will have 3 different articles in 3 different blogs, honestly I am sure that 3 articles doesn't worth 3 page of real documentation (and because in your article you cannot assume that your readers know what you are talking about, but you can do so in the second page of a wiki, and because probably the maintaners of the lib would write it better) Finally you cannot assume that the creators of a library will be always there to help us, they may change career, they may don't have time anymore for some stuff, they may move in Buthan, however you can be about sure that a wiki page will still. And again, I am not talking only about add documentation but also improve what we have now, and why not?, start something new. I don't know if there is anybody that think that it is a good idea...

The solution is simple: help out by writing or improving documentation, building demo apps, writing tutorials, and sharing success stories. All of the creators and maintainers of these projects LOVE being engaged by those interested in the project. They will take the time to help you adopt their stuff and patch up libraries to solve your specific problems (time-allowing). I think a general fund/fundraiser is a bad idea, but I'm all for a Clojure Ecosystem bounty page/site. If companies or individuals want to put monetary support behind a feature/bug-fix/tutorial, I think we should let them. This approach has worked well for Mozilla, Apache, and others. We would just have to be mindful that the bounties are for the ecosystem and not for Clojure-proper development. Don't be scared to reach out and approach the authors of the libraries you're using.

Re: [ANN] clojure-echonest-api
Yes, you right.
Definitely both atom and dynamic is too much, the idea is to set once for
the whole section at the very start, given anyway the possibility to change
it by bindig when it is necessary...
I guess that i should use only dynamic... but i got some problem changing
the var...
I should look better at the doc...

My point was that once you've declared api-key {:dynamic true} (which
by the way is not necessary if you define your api key as an atom) you
can then either bind it to a different value in a particular thread
with (binding ...) or in a particular context with (with-redef ...)[1]
This approach works fine when you regularly change your api key
depending on the context, however I'm not entirely sure how things
would work if you want to set your api-key once for an entire session.

I would think so. AFAIK, the advice has always been if you need to do
some computation on another thread don't (ab)use agents, use futures.
Additionally, you have[1]:
(def #^{:dynamic true} *api-key* (atom N6E4NIOVYMTHNDM8J))
unless you're planning on setting the key to different values in
different threads (unlikely?) you don't need to use an atom there.

Congomongo or monger ???
I don't like try to compare two different work, but when two programs have the same task, i never know... What would you suggest, congomongo or monger (or other) ? Why ? Thoughts ??? My operation would be very easy, write more than read, and update values, maybe in a future use of map/reduction... I will work a lot with json...

The problem is that this lib for some weird reason (debug i guess) print at video a bunch of information useless for me, there is any way to avoid this problem, i mean can i just print what the clojure code actually print and not what also the lib in java print ?

No, I'm sure to not use all the sequence, so I will follow your second advice, but... Cause of my non-perfect english I've not really understand the last part. Who is the caller ? You suggest something like this: (let [fl (clojure.java.io/reader path/filename) rd (lazy-reader fl)] (do-my-operation-with-lazy-reader) (.close fl)) ??? Or what ? On Dec 13, 1:20 am, Cedric Greevey cgree...@gmail.com wrote: You also probably want more efficiency. Try something closer to: (defn lazy-reader [filename] (let [rd (fn [rdr] (let [buf (char-array 4096) n (.read rdr buf 0 4096)] (condp == n -1 (.close rdr) 0 (recur rdr) (take n buf lr (fn lr [rdr] (lazy-seq (if-let [b (rd rdr)] (concat b (lr rdr)] (lr (clojure.java.io/reader filename which should buffer the reads and terminate when the stream is consumed (untested). I'm not sure how to additionally make the seq chunked. I avoided with-open to avoid the stream closing before the lazy seq is consumed. Instead, it closes only when the lazy seq is fully consumed, or when it's been discarded and the GC runs the stream's finalizer after discovering that it's become unreachable. The latter could take a while (and isn't guaranteed to happen short of the JVM exiting) so there's a risk of running out of file handles using this a lot without fully consuming the lazy seqs. If that could be an issue, I'd suggest modifying it to take a reader rather than a filename, and making the caller responsible for instantiating the reader, passing it in, (partially) consuming the sequence, and closing the reader if the sequence may not have been fully consumed. -- You received this message because you are subscribed to the Google Groups Clojure group.
