Re: Confusing Regex Behavior
Oh, handy to know. Thanks. (I come from a mostly Perl background, where regular expressions are first-class objects and operations on/with them are baked in. The Java approach to regexp that Clojure builds on is a little odd to me. But then, Perl is more than a little odd to a lot of people...)

Oh, that might be it. The newline at the end of the string might be what is throwing a wrench into things. Though, to be fair, when I used re-matches yesterday the newline wasn't an issue.

Confusing Regex Behavior
I must be doing something wrong here, but I cannot figure this out. The following results in "nil" from re-matches: (re-matches #"\[((\d+)-(\d+)-(\d+) (\d\d):(\d\d))\] (.*)" "[1518-05-27 00:42] falls asleep\n") This, however, properly matches the line and produces the backreferences: (re-find (re-matcher #"\[((\d+)-(\d+)-(\d+) (\d\d):(\d\d))\] (.*)" "[1518-05-27 00:42] falls asleep\n")) I've used re-matches many times, but this has me stumped. This is behaving this way on both 1.8.0 and 1.9.0. Randy -- Randy J.

Best Practices for Accessing Data Files That May Be Bundled?
First, some brief background/context: I've been playing around with Clojure
for a while, mostly just doing Project Euler problems. I'm taking the
"Algorithms Specialization" from Coursera, and decided to do all the
programming assignments in Clojure as a way of tackling some larger, deeper
problems. But overall, my understanding of Clojure overall is still fairly
mild.
What I want to do, is write some scaffolding around the weekly programming
tasks that automates the execution of the user-contributed test-cases. I'd
like to be able to add a new form to be tested in a single place (e.g., the
project's core.clj file) and have a re-compile be able to find out that the
new namespace is now in place, locate the test-files, and execute the form
with each test-input.
I'm pretty sure I can handle locating the test files as long as they're on
the file system (I'm looking at the fs package for walking around the file
system). But is there a way to (semi-)transparently handle the data files
being resources within the JAR, as well?
Also, how would I take a pair of strings (namespace and form-name,
respectively) and turn that into the callable function? For example, if my
set of desired test-forms were a simple nested list:
(("algorithms.class1.week1.karatsuba-mult" "karatsuba-mult")
("algorithms.class1.week2.count-inv" "count-inv")
...)
(Currently, the last ns element is the same as the function-name to call,
but some of these will have multiple implementations that I'll want to time
for comparison, so this won't always be the case.)
So, for the first "test", I want to turn
("algorithms.class1.week1.karatsuba-mult"
"karatsuba-mult") into a binding that will call
algorithms.class1.week1.karatsuba-mult/karatsuba-mult when used as a
function. I know how to do this in other languages (my strongest is Perl,
but don't hold that against me!), just not in Clojure.
The interface of all tests is the same-- they take the name of the input
file as a single input, and return a string as a result (I have
result-files in the same dirs as the input files, for comparison. I just
need to be able to iterate over the forms to test, and the test-cases for
each form.
(I say "I just need", but I'll probably be back with more questions after I
get these answered...)

Possible bug in clojure.set/union?
Hi,
Fairly-new Clojure enthusiast here, currently using Clojure to work through
projecteuler.net problems as a means of learning. While using sets on one
of the PE problems, I encountered what *might* be a bug. I admit that I
haven't searched the backlog of messages from this group or the issues on
GitHub, so if this is already known I apologize.
Here is the issue: I discovered that I could pass a list as the second
parameter to set/union, and it would be merged into the the set passed as
the first parameter and the new resulting set returned. However, if the
number of items in the list exceeds the number of items in the set, then
the return value is a list with any duplicate elements completely present.
To illustrate, here is a snippet from my REPL:
user=> (require '[clojure.set :as set])
nil
user=> (set/union #{1 2 3} #{2 3 4})
#{1 4 3 2}
user=> (set/union #{1 2 3} #{2 3 4 5})
#{1 4 3 2 5}
user=> (set/union #{1 2 3} (list 2 3 4))
#{1 4 3 2}
user=> (set/union #{1 2 3} (list 2 3 4 5))
(2 3 1 2 3 4 5)
Note that the last expression yields a list of 7 elements rather than a set
of 5.
I have not tried this with more than two arguments, so I don't know that
would affect the output. I did try putting a list as the first parameter,
and that results in a list return value all the time.
Is this a bug? Should I file a GitHub issue on this? I first encountered
this in 1.7.0, but I recently updated to 1.8.0 and it is still present.

Re: Clojure, Swank, and Leiningen with Emacs on Mac OS X
The contents of .clojure are not at issue, clojure runs just fine from the command-line, repl, etc. My problem is with installing SLIME, clojure-mode, etc. without using package.el. When I tried it, it failed somewhere in the building/compiling of clojure-mode.el, and the SLIME package was not complete. Starting with the ESK is not an option for me, as I have too much invested in my current emacs configuration. Currently, I keep my emacs configuration on github, as part of a larger repo that houses all my dot-files (I really should move the emacs stuff into its own repo, now that I think about it). So I have no problems with downloading the packages I need, installing them into my configuration manually, etc. I don't mind doing things in a slightly harder way than the ESK presents, I just need to know which versions of things like SLIME I should use (the SLIME web page only has a download for the latest CVS head version).

Re: Clojure, Swank, and Leiningen with Emacs on Mac OS X
I am also having some big problems getting a working set-up under MacOS. I can't really start with the emacs-starters-kit, as I have a very large existing configuration. And Aquamacs doesn't ship SLIME as part of the distribution. Mainly, I need to know the best place to get the clojure-mode, clojure-test-mode, slime and swank-clojure packages. I tried using package.el to get some of them, but it bombed out before it completed building/installing slime or clojure-mode. I considered getting slime from their web page, but their only download link is a CVS snapshot, and I seem to remember reading somewhere that the really-new slime versions had some problems. Is part of the problem my decision to use Aquamacs? I looked at Carbon Emacs as well, but that's based on an emacs 22 source base, and I'd prefer to work from 23 or newer (my Linux desktops are running emacs in the 23 range). Do people roll their own emacs for clojure development on MacOS?

I sometimes include apache commons-io and clojure-contrib1.2 without any problems. I also included a sql connection library for one of the problems, so it seems fine :) For those puzzles that require command-line processing, have you used a library to do it? Looking in both Programming Clojure and Practical Clojure, the only instruction I can find on handling command-line args involves AOT compilation of your class and definition of a -main method. I'm not sure how well this would work with the submission model that Coderloop uses. I'm afraid I'm still *very* new to Clojure, and while it would be easy (for me) to solve the problems in other languages, the point of the exercise (for me) is to use Coderloop's problems to help myself in learning Clojure...

Having trouble with reader.tasklist class from Programming Clojure
Hello everyone. I am just starting out in Clojure by working through Programming Clojure. I have run into a snag, though, on the reader/tasklist.clj example in chapter 3. I am getting the following error consistently: user= (compile 'reader.tasklist) java.lang.ClassNotFoundException: reader.tasklist (tasklist.clj:13) Line 13 is this line in the task-list defn: (let [handler (new reader.tasklist)] My complete reader/tasklist.clj is: (ns reader.tasklist (:gen-class :extends org.xml.sax.helpers.DefaultHandler :state state :init init) (:use [clojure.contrib.duck-streams :only (reader)]) (:import [java.io File] [org.xml.sax InputSource] [org.xml.sax.helpers DefaultHandler] [javax.xml.parsers SAXParserFactory])) (defn task-list [arg] (let [handler (new reader.tasklist)] (.. SAXParserFactory newInstance newSAXParser (parse (InputSource. (reader (File. arg))) handler)) @(.state handler))) (defn -main [ args] (doseq [arg args] (println (task-list arg (defn -init [] [[] (atom [])]) (defn -startElement [this uri local qname atts] (when (= qname target) (swap! (.state this) conj (.getValue atts name I've compared this very thoroughly to examples/tasklist.clj in the Github dist, but can't find any errors. I'm working in a directory that has a reader sub-dir and a classes sub-dir. tasklist.clj is in the reader directory. My REPL is launched from my own hand-rolled launcher, but the command it executes is basically: java -cp .:/home/users/rjray/lib/clojure/clojure-contrib.jar:/home/users/rjray/lib/clojure/clojure.jar:/home/users/rjray/lib/java/jline.jar jline.ConsoleRunner clojure.main Everything up to now has run fine from within the REPL, this is the first time I've tried compiling a class. I get the same error if I try C-c C-k from a SLIME-enabled buffer in Emacs, as well. Any suggestions? Randy -- Randy J.

When I ran it, I was in the directory that contains reader (and classes), and . was in my classpath. I ran it with the bin/repl.sh in the github distro, and it successfully compiled the class. I noticed that *that* REPL was using 1.1.0-alpha-SNAPSHOT. So from the exact same directory (with reader and classes in the current directory) I ran: java -cp .:/home/users/rjray/lib/clojure/clojure-contrib.jar:/home/users/rjray/lib/clojure/clojure.jar:/home/users/rjray/lib/java/jline.jar jline.ConsoleRunner clojure.main Note the . at the head of classpath (plus, it's finding the class to start compiling it, it just isn't finding it when it references itself). The paths to clojure.jar and clojure-contrib.jar are the 1.2.0 distribution jars, stock downloads from clojure.org. And with that REPL, it reported the error. Randy -- Randy J.
