core cache/memoize issue?

Hi, I have been exploring to use core.cache and core.memoize in our clojure app and have found several issues. Those issues should have been directed to Fogus but just in case anyone has clues. core.cache (v0.6.0): 1) it appears the cache is "broken" once two entries with a same key with di

Re: iterate with side-effect function?

Nathan, Thanks for the explanation, what i'm trying to do is to "repeatedly" run a side-effect function until the return value of it meets certain criteria. It could have been done using loop/recur as shown below, and wondering if there's alternatives. Is a there general approach to accomp

iterate with side-effect function?

Hi, From clojure doc, it states iterate takes a side-effect free function, and what's the implication if the function has side-effect as follow? (->> 0 (iterate (fn [cnt] (prn cnt) ;; save data to csv (Thread/sleep 6000) (inc cn

Re: Parsing double with default value

Alan, Your with-default fn is neat. So it appears there's no idiomatic/built-in clojure fn/macro to do parsing and wrapper functions such as follow would be needed to avoid typing the whole expression every time. (def parse-double (with-default #(Double. %) 0.0)) (def parse-int (with-defaul

Re: Parsing double with default value

Tassilo, The reason a generic default macro being used here is because we can use the same macro to parse other data type like integer: (with-default 1 (Integer. my-value)) Thanks, siyu -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to

Parsing double with default value

Hi, Is there an idiomatic/built-in way to parse double with a default value if there's exception? Currently we use a generic with-default macro to ignore exception and return default value as follow: (with-default 0.0 (Double. my-value)) -- You received this message because you are subscri

Re: A simulation of the Monty Hall Problem

Hi, I started learning clojure for a few months and this is what I have for the problem, and I find it running very slow if exceeding 100k trials, maybe it's because of using set? Any feedbacks will be appreciated. thx (require '[clojure.set :as set]) (def doors #{:a :b :c}) (defn rand-nth-set

Re: [ANN] fs - file system utilities for Clojure

Miki, We do have functions to normalize and convert path and I just think the dirname function should not do the conversion. In fact there's no benefits to do so as /a/b/c on *nix is not equal to \a\b\c in window, same goes for c:\a\b\c in window for c:/a/b/c in *nix. In 99.99% percent of th

Miki, Thanks for the quick response, but I'm not just looking for a fix for the testcase, I'm looking for the dirname function to return the same output regardless of the machine that the code is running on, eg (dirname "/a/b/c") should return "/a/b/" on both win and unix just like the getFull

Re: [ANN] fs - file system utilities for Clojure

Hi Miki, The dirname testcase fails on Window. Does it make sense that even if it's running on window it should still pass? In another word, don't you think that it should not convert the separator implicitly? (deftest dirname-test (is (= (dirname "/a/b/c") "/a/b"))) user=> (fs/dirname "/

Re: [ANN] fs - file system utilities for Clojure

Hi Miki, We are planning to use this file system utilities, and we need a function to get file extension. Currently we're using apache common for that, but we want to get rid of apache common altogether. Can you add this functionality to the fs.clj? Thx Si Yu -- You received this message b
