Re: Lein uberjar hangs when swank is required in the namespace.

2011-05-06 Thread J.R. Garcia 
Are you sure you really want/need swank as a dependency? If you just
need to run swank for interactive development put it in dev-
dependencies.

Re: ANN: Jark 0.3 (using the nrepl protocol)

2011-05-06 Thread Ambrose Bonnaire-Sergeant 
Hi Paul,

We haven't started on a VimClojure nREPL fork yet.

We should probably ask Meikel if he's already tackled it, there is a "nrepl"
tag on
bitbucket but it's about 6 months old.
https://bitbucket.org/kotarak/vimclojure/overview

Thanks,
Ambrose

It's great to see nREPL being used for such things.

FYI, I just released nREPL 0.0.5, adding Clojure 1.3.0 alpha
compatibility:

https://github.com/clojure/tools.nrepl

Do let me know if you have any difficulties, questions, etc.  There's
also now an issue tracker:

I still need to do a brain-dump of TODOs into it, but that'll come
shortly.  If you have specific bug reports, feel free to file them
there.

Right, Adam. As Armando pointed out, Clojure 1.3 at least doesn't fail
in the case I brought up. I would be very interested to learn what has
changed in the Clojure 1.3 source code (compared to 1.2) to achieve
this.

I don't think anyone expects quick sort to compare equal to bubble
sort or anything like that. I think the issue is to get two functions
with the same textual representation to compare equal.

Lein uberjar hangs when swank is required in the namespace.

2011-05-06 Thread Trastabuga 
Hi

I got a problem including swank into the project.
I created a simple test project with "lein new test"
And modified the project.clj and core.clj files so they look like:

project.clj:
(defproject test "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :main test.core
  :dependencies [[org.clojure/clojure "1.2.1"]
[swank-clojure "1.2.1"]
])

core.clj:
(ns test.core
  (:require swank.swank)
  (:gen-class)
)

(defn -main [& args]
  (println "hello " args))


Now if I run "lein uberjar" it hangs after saying "Copying 2 files to
D:\Dev\test\clojure\projects\test\lib"
If I comment out the (:require swank.swank) line, it works.
Also if I uncomment (:require swank.swank) and comment out :main
test.core line in the project.clj file it also works.

Why lein hangs and how can I fix it?

Thank you,
Andrei

Re: Eval destroys equality

2011-05-06 Thread Andy Fingerhut 
Caveat: The following fact may already be well known to those discussing this 
issue, and I may not be clear on the goal of this effort.

If the goal is to have functions compare as equal whenever they are equivalent 
in some sense, then that is an undecidable problem, even if the two functions 
are restricted to pure functions with no side effects and closed over no vars.  
The proof is nearly the same as that for the halting problem.

Of course, it is still decidable to get the correct answer for some restricted 
kinds of functions.  If that is what you are after, go for it.

This should not be a requirement. However, you might need to require the 
namespace containing the class before using the class.

The standard Clojure repl uses some utility fns from non-core namespaces. 
Specifically:

 ;; from main.clj
 (use '[clojure.repl :only (source apropos dir pst doc find-doc)])
 (use '[clojure.java.javadoc :only (javadoc)])
 (use '[clojure.pprint :only (pp pprint)])

When you run code outside the REPL, you will need to use these specifically if 
you need them.

Hope this helps.

Re: Search for a node querying on attrs

2011-05-06 Thread Islon Scherer 
This is what I did:

(let [nodes (html/html-resource (StringReader. body))
   meta-extractor (fn [m attr] (first (filter #(= (->
% :attrs :name) attr) m)))
   metas (html/select nodes [:meta])
   title (-> (meta-extractor metas "title") :attrs :content)

   date-raw (-> (meta-extractor metas "date") :attrs :content)
   keywords-raw (-> (meta-extractor metas
"keywords") :attrs :content)
   keywords (string/split keywords-raw #", ")]

Hope it helps.

RE: Jark 0.3 (using the nrepl protocol)

2011-05-06 Thread Bhinderwala, Shoeb 
I am trying to install jark on a Linux server and running into issues. I
am trying to follow the exact instructions as mentioned on the website:

  http://icylisper.in/jark/start.html

I added the following bin directory to my PATH variable:
/home/BhindSA/bin

I downloaded jark-0.3 and copied it to file name jark:

cp jark-0.3 /home/BhindSA/bin/jark

When I run: jark self install, I get the following error:

/home/BhindSA/bin/jark: line 296:
/home/BhindSA/.config/jark/bin/jark-client: No such file or directory

I tried creating the directories in .config, but still get the same
error.

What am I doing wrong? Can the instructions on the website be made
clearer?

Subject: ANN: Jark 0.3 (using the nrepl protocol)

Hi,

It is a pleasure to announce the release of Jark 0.3, today.

Why Jark?
Startup time of the Java Virtual Machine(JVM) is too slow and thereby
command-line applications on the JVM are sluggish and very painful to
use.
Jark is an attempt to run a persistent JVM daemon and provide a set of
utilities to control and operate on it.
It should help in deploying clojure applications on the JVM, running
command-line applications written in clojure and remote-debugging.

The motivation is also to provide a very thin nrepl-client that can
run on any given OS platform. Maybe one on the Android. The client
host need not even have the JRE installed. The current implementation
is in python(2.6 or 2.7) as a proof-of-concept and runs only on
GNU/Linux and Mac OSX.

Get started: http://icylisper.in/jark/start.html

Jark has utilites for:
a. Operating and tuning the JVM
b. Managing classpaths
c. Managing packages and repositories that are not project-specific
(uses cljr)
d. Scripting (#!/usr/bin/env jark)  and namespaces.
All of which can be done remotely.

This is a sample usage:
server> jark vm start [--port]
client>  jark vm connect [--host] [--port]
client>  jark repl
---
client>  jark vm stat
client>  jark cp list
server> jark cp add 
client>  jark package install -p PACKAGE -v VERSION
client>  jark ns load /path/to.clj
and so on ..

The earlier version (0.2) of jark used nailgun as a proof-of-concept
server and client. The current release (0.3) of jark uses Chas
Emerick's nrepl protocol for communication. I hope to rewrite the
client in haskell, so native binaries can be generated, sometime soon.
Have a look at the roadmap:

problem running tests in leiningen

2011-05-06 Thread Islon Scherer 
I have a lein project and I'm trying to run my tests with lein test.
The first problem I had was a class not found error in one of my
records
so I put "aot: [namespace.name]" in project.clj.
It's required that I put all namespaces that contain defrecords/
deftypes in the aot list?

After that I tried to run the tests again and got a different error:
Exception in thread "main" java.lang.ClassNotFoundException:
clojure.pprint
Inside lein swank this code runs and compiles with no problems, do
lein
execute tests with a different clojure(and/or contrib) version?

This is my project.clj

(defproject mediaretriever "1.0.0-SNAPSHOT"
  :description "..."
  :dependencies [[org.clojure/clojure "1.2.1"]
 [org.clojure/clojure-contrib "1.2.0"]
 [enlive "1.0.0"]
 [clj-http "0.1.3"]
 [clj-time "0.3.0"]]
  :dev-dependencies [[swank-clojure "1.3.0"]]
  :aot [mediaretriever.media])

Any help is appreciated.
Regards
Islon
