Re: another question on macros defining functions
You don't need to use eval to create a function dynamically in a macro.

The problem here is that macros run at compile time, but let bindings exist at run time. If you need the name to be determined at run time you will need to use eval. If you don't need the name at run time, why are you using (let [eff "gee"] (foo eff)) and not simply (foo gee)?

another question on macros defining functions
Hi Here's another macro-noob question. (Thanks for the help on the previous question and please do let me know if stackoverflow is a more appropriate place to ask noob questions.) I'm trying to write a macro (or a function) that defines/declares specifically named functions. In (let [eff "gee"] (foo eff)) I want the macro foo to define/declare a function called foo-gee, not foo- eff. What should I do differently? First attempt: (defmacro foo [x] (let [name# (symbol (str "foo-" x))] `(defn ~name# [] ( (let [eff "gee"] (foo eff)) => #'user/foo-eff Second attempt: (defmacro foo [x] `(let [name# (symbol (str "foo-" ~x))] (defn name# [] ( (let [eff "gee"] (foo eff)) => #'user/name__4807__auto__ Third attempt: (defmacro foo [x] `(let [name# (symbol (str "foo-" ~x))] (defn ~name# [] ( (let [eff "gee"] (foo eff)) => First argument to def must be a Symbol [Thrown class java.lang.Exception] -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Announcement: stockings clojure library for easy access to financial data
Not exactly. It is more a client API that exposes data from different web services in a consistent way. It takes care of all the tedious stuff: figuring out the right URL and query parameters, parsing the JSON, XML, or CSV responses, handling errors, fixing quirks (e.g. inconsistent time zones in date and time fields or stock symbols that do not allow for a stock exchange prefix); that kind of stuff. Try it out; the README.rst file is full of examples. fxt On Jun 2, 2:30 am, MohanR wrote: > Is that something like a mashup ? > > Thanks, > Mohan -- You received this message because you are subscribed to the Google Groups "Clojure" group.

+1 on the atlas. It's a great way to "surf" clojure.

Re: Best/Idiomatic way of managing data that changes
Hmm, I posted replies to the previous posters but I might have sent them directly. Apologies. Thanks everyone for the replies, in terms of the game loop itself, it is more or less dictated by using processing, so basically there're callbacks for mouse events and for re-drawing the screen so that's taken care of. In terms of the data itself, I was a bit wary of using the ID approach instead of a big massive data structure with everything in it. I somehow felt this was making things mutable in a way, but I am convinced by the replies. In terms of code elegance, I overlooked how elegant update-in can be, as opposed to assoc-in, and using a set in conjunction with judicious structuring of the data, as Meikel and Jeff suggested, will definitely make things far far more elegant. Thanks for the replies, this is a great group! On Jun 2, 10:10 am, Jeff Rose wrote: > I think the type of data structures you use will depend on how you > need to access the data.

possible bug in cl-format (rounding floating-point number)

I rewrote part of it to use BigInteger, and it seemed to fix the problem, but I didn't test it extensively. It might be a valid solution in any case. Incidentally, I love using clojure.pprint. It's powerful, and after diving into the CLM spec I have new appreciation for the daunting task it must be to test it. -Travis -- You received this message because you are subscribed to the Google Groups "Clojure" group.

find-doc retrieves too other things though.

update xml attribute value
Hi, Does anyone know how to update xml element attribute value on the zipper data structure? I have something like (:require (clojure [xml :as xml] [zip :as zip]) [clojure.contrib.zip-filter.xml :as zf]) (let [src (-> "c:/my.xml" io/file xml/parse zip/xml-zip) edf (zf/xml1-> src :root :element1) n(-> (zf/attr :description) (zip/replace ""))]) and this is giving me java.lang.ClassCastException: java.lang.Character cannot be cast to clojure.lang.Associative (test-xml-zip.clj:0) Thanks, -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: library or namespace doc helper function from repl?
(ns-publics 'namespace) will show all the publicly defined things in a namespace.

library or namespace doc helper function from repl?
Apologies for a silly question, there must be a simple way to do this from the repl, but I can't seem to find it… Is there a way from the repl to view all available functions in the library or namespace? It often happens that I know a library contains functionality I seek, but I don't yet know the name. I realize that I can try to use the Atlas url (which is awesome) or an IDE or check github, but it would be really nice not to have to leave the repl. In R I would do: library(help=libname) Thanks in advance, Avram -- You received this message because you are subscribed to the Google Groups "Clojure" group.
