I think you can just use the update-in function like: 1:1 user=> (def m {:a {:b {:c {:d 3) #'user/m 1:2 user=> (update-in m [:a :b :c :d] - 5) {:a {:b {:c {:d -2 On Sun, Jan 11, 2009 at 11:08 AM, CuppoJava wrote: > > Hi, > I'm just wondering if there's a clever way of creating a new ma

Re: How to create and read from a stream of random characters?

Chouser's solution works well, but I found that you can end up with an empty string sometimes or never getting the maxlength that you passed in. 1:2 user=> (take 3 (seq-of-rand-strings 10)) ("ngene" "" "dwlbzndqx") I added an inc before calling the take and that clears things up. (defn seq-of-ra

Here's an example of *1 *2 *3 1:1 user=> (str "gavin") "gavin" 1:2 user=> (str "teri") "teri" 1:3 user=> (str "brian") "brian" 1:4 user=> (str-join " " [*1 *2 *3]) "brian teri gavin" On Wed, Jan

Re: Newbie: Separating and grouping the elements in a bunch of vectors

Is syntax quote "reader" only?

I'm a bit mystified how syntax quote does what it does. I don't see how syntax quote can quote the whole while unquoting parts without some evaluation-time intervention. If I had to implement it myself, I'd just punt the problem to evaluation-time by introducing a special form 'unquote', e.g.:

Importing lots of Java classes at once

One could argue that wildcard imports in Java (import package.*) are evil, pollute your namespaces, create potential naming conflicts, etc. One would probably be correct. One could also argue that having to manually type a list of dozens of classnames is pretty tedious, especially if all you wan

clj-web-crawler

I wrote a Clojure script that wraps the Apache commons-client library for crawling the web. It's a simple 125 line script and I also wrote some test cases for it as well. I was wondering if this is something that could/should be included in clojure.contrib or if it should be a standalone Clojure

advice needed converting large files to xml

I've been using Clojure for about 6 months now and really like it. I am somewhat new to multi-threading and using any of the parallel features in Clojure though. I have a situation where I need to convert 7 files from CSV to XML. Each one of these files is about 180MB apiece in size. I have d
