Re: ANN: Gloss, a byte-format DSL
The later. The string in my example is \n terminated, so it should read past the \0, and then the outer list should terminate on the last \0. My point is that I need to parse recursive structures, which of course contain the same terminator as the outer one. What if I wanted to parse null terminated lists of null terminated lists of ... of bytes? Like so: abc\0def\0\0 def\0ghi\0jkl\0\0 \0 Your implementation would just make the outer list read to the first \0 and call it a day. What I need is that it only checks for a terminator on the outer list after reading a full inner list, and keep doing that, until it finds a terminator right after the inner list.

Interesting.
My downloaded version of clojure 1.2.0 acts exactly as you describe.
However my basic lein project with only
(defproject prj "1.0.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.2.0"]]])
acts differently.
Well as I said, I can never sure about anything :)

FWIW I've been using this (Eclipse/Counterclockwise) both for my own work and for teaching an undergraduate class last fall, and I think it is quite good. My one serious lingering complaint, which is leading me to explore other options again, is the way Eclipse does (or doesn't) handle dependencies and builds. Leiningen and/or Cake seem to make many things easy that are a pain in the Eclipse world. If I could combine these things in some reasonably smooth way then I'd be very happy. As it is I'm now playing with Cake/Textmate as a possible replacement. (Also FWIW I started with emacs, having used that for a long time in other contexts, but don't find that to be a good long-term approach for a variety of reasons that I won't belabor here.) -Lee -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: which IDEs are you all using?
Indeed, I use Eclipse + counterclockwise as well -- to the point of contributing to it of late. IMVHO, the Eclipse + counterclockwise combination is the one that has the most potential in the IDE space (for those of us that can't bear to work with emacs). Check out the v0.2.0 RC[1] that went out a little while ago that includes a vastly-improved network-capable REPL (based on the new nREPL project[2]).

ANN: lein-cdt 1.0.0 - a leiningen plugin for the Clojure Debugging Toolkit
Hi folks I'd like to announce the first stable release of lein-cdt, a leiningen plugin that makes running George Jahad's excellent Clojure Debugging Toolkit a little easier. George has been polishing CDT over the past couple weeks and we both hope that this plugin will help others start to use and provide feedback on this tool: https://github.com/travis/lein-cdt http://clojars.org/lein-cdt This release includes: lein cdt - a leiningen task to start a CDT REPL that will automatically connect to a running debug JVM lein cdt-emacs - a leiningen task that will download necessary binary and source dependencies to a central location and print instructions for setting up emacs integration with CDT Nota bene: * The 1.0.0 status of lein-cdt implies that lein-cdt's API is relatively stable - easy to do because it's not a lot of code. It does not imply anything with regards to CDT itself. * Some important limitations are noted on the GitHub page - please be sure to read through these before reporting issues.

Re: ANN: Gloss, a byte-format DSL
Oh, right. My code does have a start and an end. I'm using header for the start. So the only way Gloss could do this is with a fn that combines header and repeated into one?

Re: ANN: Gloss, a byte-format DSL
I don't know if your example codec is as simple as your real problem, but here's a codec that will work for the string you provided: (repeated (string :utf-8 :delimiters ["\n" "\n\0"]) :delimiters ["\n\0"] :strip-delimiters? false) This terminates the whole sequence only on \n\0, but doesn't strip out the terminator so that it can be used by the last string as well. Right now this will not properly encode (the last token will be \n\n \0, so there will be a spurious empty string at the end of the list), but I plan on fixing that soon.

ANN: PoolradWheel, a "translation wheel" for 3 classic AD&D games
In the late 80's SSI Published a series of AD&D computer games starting with Pool of Radiance [1]. Some of these came with a decoder Wheel required to enter the game and at some points during game play. This program simlates the decoder wheel as required for entering the game. [1] http://en.wikipedia.org/wiki/Pool_of_Radiance In its present form, it doesn't implement glyph-at-a-time translation which is occasionally required during game play. You can find it here: https://github.com/bpsm/poolradwheel.clj I realize that there are probably about 7 people on the entire Internet that might be interested in what this software does. My primary purpose in writing it was as an example with enough Swing UI to be interesting. It's also a port of an earlier Java (1.4) version, allowing me to compare the the feel and expressiveness of the two languages for this particular task. For those wishing to form their own opinions on these questions, the Java version is here: https://github.com/bpsm/poolradwheel.java The part I'm least happy with is the Model/Controller, though I can't put my finger on why I don't like it. It just feels kind of kludgy.

Re: Odd behavior calling a fn "test" or "try"
To expand on this: user=> (defn try [] 5) #'user/try user=> (try) ; `try` alone is resolved to the special form nil user=> (#'try) ; obtaining the `try` var works just fine ; (vars currently delegate function calls to their values) 5 user=> (@#'try) ; explicitly deref'ing the fn from the `try` var and invoking it 5 So, you *can* shadow the binding of try (or any special form) within a given namespace, but you also need to resolve the var in question yourself (since regular symbols naming special forms are always given priority without the #' syntax [or use of the `var` macro]). None of that is required for regular functions, the resolution of which always takes into account the current namespace and its interned/referred vars. - Chas On Jan 10, 2011, at 8:51 PM, Stuart Halloway wrote: > Hi Tom, > > "try" is a special form, and "test" is a function. > > Stu > >> I know I should not be naming my functions the same thing as ones in >> core but was surprised when I wrote the following >> https://github.com/thattommyhall/tth-SICP/blob/master/1-35.clj >> I have being doing the SICP stuff in clojure and accieently copied >> "try" as the fn name and it did not work, I noticed a colleague chose >> "test" and it did work, but test is in core too so I don't get the >> difference. >> >> Playing around on the repl I get >> user> (defn try [] ()) >> #'user/try >> user> (defn test [] ()) >> WARNING: test already refers to: #'clojure.core/test in namespace: >> user, being replaced by: #'user/test >> #'user/test >> user> (try 1) >> 1 >> user> (test 1) >> Throws "Wrong number of args (1) passed to: user$test" (as you would >> expect from my defn of test) >> >> user> (user/try 1) >> and >> user> (user/test 1) >> both >> throw the error. >> >> >> Why can test be shadowed and not try?

Question about sorted-sets
All,
I'm hoping another, wiser set of eyes can help me to see what I'm doing
wrong.
I've defined a deftype below that stores a likelihood and a tree structure
(nested vectors). The deftype overrides equals, etc, and implements
Comparable so I can add SearchResults to a sorted-set and sort by
likelihood. Equal SearchResults have the same likelihood and have
quasi-isomorphic tree structures.
(deftype SearchResult [lik tree]
Object
(toString [sr]
(str lik ":" tree))
(equals [sr other]
(and (= lik (.lik other)) (quasi-isomorphic? tree (.tree other
(hashCode [sr]
(int lik))
Comparable
(compareTo [sr sr2]
(cond
(= sr sr2) 0
(> (.lik sr) (.lik sr2)) -1
:default 1)))
I've defined some dummy data, which should illustrate the unusual behavior
I'm seeing when I add SearchResults to a sorted-set.
user> (def t1 [{:name 0} [{:name 1} [{:name 3}] [{:name 2}]] [{:name 4}]])
user> (def t2 [{:name 0} [{:name 1} [{:name 2}] [{:name 3}]] [{:name 4}]])
user> (def t3 [{:name 0} [{:name 1} [{:name 4}] [{:name 2}]] [{:name 3}]])
user> (def t4 [{:name 0} [{:name 1} [{:name 4}] [{:name 3}]] [{:name 2}]])
user> (quasi-isomorphic? t1 t2)
true
user> (quasi-isomorphic? t1 t3)
false
user> (quasi-isomorphic? t1 t4)
false
user> (def sr1 (SearchResult. 1 t1))
user> (def sr2 (SearchResult. 1 t2))
user> (def sr3 (SearchResult. 1 t3))
user> (def sr4 (SearchResult. 1 t4))
user> (= sr1 sr2)
true
user> (= sr1 sr3)
false
user> (= sr1 sr4)
false
user> (def ss (sorted-set))
true
user> (count (conj ss sr1 sr3 sr4 sr2))
4
user> (count (conj ss sr1 sr2 sr3 sr4))
3
Of the four SearchResults, only sr1 and sr2 should be equal per the equals
and compareTo functions defined in SearchResult. Based on that assumption,
I thought that evaluating (conj ss sr1 sr3 sr4 sr2) would only return a set
containing sr1, sr3, sr4, but it actually returns a set containing all four
SearchResults. However, if I change the order of the SearchResults, as
in (conj ss sr1 sr2 sr3 sr4), it works as expected, returning the set
containing sr1, sr3, sr4.
I've tried debugging the equals function to see what, exactly, is being
compared, and it looks like in (conj ss sr1 sr3 sr4 sr2), sr2 is never
actually compared to sr1, so sr2 gets added to the set. What am I missing?
Any help would be greatly appreciated.
-Travis
p.s. Yes, the hashCode function isn't the best, but from what I could read,
it does fulfill the requirements of the contract outlined in the javadocs.

My guess is that it's your likelihood function that's actually broken.
If sr1 and sr2 don't come out with the same likelihood, then in some
cases of putting them into the sorted set they'll never end up
compared with each other for equality. (Actually, I'd have thought in
all cases. Perhaps the compareTo is separately broken and doesn't
total-order by likelihood?)

ANN: clojurejs -- a Clojure (subset) to Javascript translator
Hi all, I've just released a stable version of `clojurejs' -- an unimaginatively named Clojure library for translating a Clojure subset language to Javascript. clojurejs is something I've been working on for a few weeks as part of a larger web app in Clojure. The code's a bit crufty (reflects my incremental discovery of the inconsistencies in Javascript), but functional and I wanted put something out there for people to check out. I welcome bug reports and feedback. It's been useful for my specific needs, and I'd be happy if it's even marginally useful to others. I realize there are a number of other efforts to compile/translate Clojure (or other Lisp subset) to Javascript, but nothing quite fit my requirements, which prompted me to build clojurejs. Some useful aspects of clojurejs are: * Consistent scoping in let and loop/recur forms * Macros * Implicit return * loop/recur translates to Javascript for loops * Translates Clojure vectors, strings, keywords, symbols and maps to Javascript equivalents * dot form access to methods and properties * Adds a couple of Clojure incompatible special forms for Javascript specific behavior If this seems interesting I've posted a more detailed entry on my blog (http://cynojure.posterous.com/clojurejs-a-clojure-subset-to- javascript-tran). Oh, and the github link: http://github.com/kriyative/clojurejs Look forward to feedback. Cheers, -ram -- You received this message because you are subscribed to the Google Groups "Clojure" group.
