Re: Clojure Quizzes?
Taking a page out of the python book , I like to include a statement at the end that checks to see if the program is being run as a command-line program and then respond accordingly. As an example, (if (command-line?) (your-awesome-function (read-integer (first *command-line-args* Might appear at the end of my file. command-line? and read-integer are listed below (ns coderloop.utils (:use [clojure.contrib [duck-streams :only [file-str read-lines]]]) (:use [clojure [string :only [trim blank? split]]])) (defn read-integer [file] (Integer/parseInt (trim (slurp (file-str file) (defn command-line? [] (.isAbsolute (java.io.File. *file*))) This has the advantage of also working when the namespace is being run on the command-line with no arguments, but not when the namespace is being used or required by another namespace. read-integer is just a simple example for how to read a single integer from a file. You can then actually run your program by making a shell script with something like #!/bin/bash java -Xmn500M -Xms2000M -Xmx2000M -server -cp ./lib/*:./src clojure.main your-namespace-file.clj $@ A little known fact is that the above can actually be embedded into a clojure source file with the following trick: Make this the first line of your clojure namespace to make it executable: :;exec java -verbose:gc -Xmn500M -Xms2000M -Xmx2000M -server -cp your-classpath clojure.main $0 $*; The trick is putting the :; at the beginning and then calling exec. To clojure this looks like a literal string followed by a comment. To bash it looks like a no-op followed by an invocation of java on the file itself, and no lines after the first ever get executed. You can make whatever class structure you cant and then just symlink the clojure file to be an executable file at the base of the directory. You can still always go the shell script route if you don't like the embedding trick. This technique is common with emacs-lisp to make things executable.

Re: Clojure Quizzes?
Because there is a limit on the length of the shebang line to as short as 80 characters in some distributions (notably ubuntu), and the posix standard for the shebang line does not allow you to pass any arguments to the interperter to modify its behaviour --- so no classpath or anything else for you!

It's got foreach loops, mutable arrays, and boolean logic, and that's one particular set of operations to simulate a Turing machine. I read somewhere that it suffices to have a program counter, a register, four stacks, jump-back-or-forth-N-steps with a small bounded N, if register zero then next instruction otherwise skip one instruction, increment register (which wraps at some value), and peek or pop for each of the four stacks (to the register). Alternatively, a program counter, a stack, a cursor into an infinite deque, and these eight instructions: increment at cursor, decrement at cursor, jump amount at cursor, if zero at cursor next instruction else skip, cursor left one, cursor right one, push program counter, pop program counter. The universal Turing machine concept suggests that there's an instruction set for which only the infinite deque is needed, with cursor-left, cursor-right, and some additional instructions, but no long range jumps within the deque, and instructions also fetched from the deque with no separate program counter. It would be a real bitch to program, though. The general rule seems to be that a) there has to be at least one if-something condition that alters flow, say by optionally skipping one instruction that can be a longer-range jump and may be followed by another such; b) there has to be a backward jump possibility; and c) there has to be some kind of memory -- either bidirectionally infinite and cursor-navigable like a giant ArrayList, or at least four stacks that can be separately peeked and popped. With just one stack you can apparently get a big subset of fully general computation but not the whole deal. There also has to be d) arithmetic of some kind, on the memory content and interacting in some way with the if condition. http://en.wikipedia.org/wiki/Turing_machine http://aturingmachine.com/ I see your Turing machine and raise you this: http://www.rezmason.net/wireworld/ -- You received this message because you are subscribed to the Google Groups Clojure group.

If anyone's interested, I'd love to hear his/her thoughts on this code. A few thoughts: Should it automatically AOT compile everything and package it all in an executable jar? Can I use a pure java implementation of bzip and tar without calling out to the system's tar command?

Re: Clojure Quizzes?
Thanks Sean and Benjamin. I've started at Coderloop and I must admit that I'm hooked. I'll take a look at Project Euler next, once I'm done providing suggestions and finishing a few more quizzes at Coderloop. :-) Now I'll have to hit the IRC channel to get help on some minor issues so as not to spoil any of the quizzes I'm trying to take on. Thanks again.

Clojure in Action, so my Clojure skills are sub-sub-par at the moment), but I was wondering if there were any weekly challenges for writing Clojure code like there is (was?) for Ruby, i.e: http://rubyquiz.com/ When I was starting my investigation into Ruby I found this type of weekly quiz incredibly insightful. Is there something similar for Clojure? Even Lisp would be fine, and I would think it would be interesting to compare approaches from others in the group. Thoughts? Project Euler is something you might look at - it offers a variety of interesting problems that you can solve in any language (and I think it's particularly good for solving the same problem in multiple languages so you can compare them in the same context, which I find really helps me 'get' new languages). I think the Ruby Quiz is a great idea but I suspect it is a huge amount of work behind the scenes... -- Sean A Corfield -- (904) 302-SEAN Railo Technologies, Inc. -- http://getrailo.com/ An Architect's View -- http://corfield.org/ If you're not annoying somebody, you're not really alive. -- Margaret Atwood -- You received this message because you are subscribed to the Google Groups Clojure group.
