The elisp in there might give you some ideas on how to get some of the glow effects. Oh nice, I hadn't seen highlight tail mode before.

The glow effect I was referring to as the Final Cut Express fx is the persistent shine you see on all the text which makes it look like a retro games console. reich-score is really impressive. Looking forward to playing with the new features. Do you mean the Reich technique or the ascii-art? The ascii-art was hand-crafted and assigned to a snippet shortcut (reich-score). I used yasnippet (http://www.emacswiki.org/emacs/Yasnippet) and the following snippet text https://github.com/overtone/live-coding-emacs/blob/master/etc/snippets/clojure-mode/reich-score If anyone else has any tips on how to make your Emacs look fun and fancy - particularly in the context of using it as a presentation tool, I'd love to hear them!

Re: Contrib.Logging enhancements: set-log-level!, spy for lazy sequences

Ideally, we can just cover the common base case, and expose machinery for the user to configure any non-standard situations as required. I imagine 80% of the time the logging library is used, the user is not going to be setting up any logging hierarchies of any kind. There should be a simple function that sets all logging levels to the given level to cover that 80% base case. People who need something more elaborate are going to be doing a lot of customization anyway... we don't need to cover every possible case, just the most common ones. The multiple backeds problem is indeed pretty annoying. The Clojure- level library would have to know about each and every backend and all its quirks to be able to do the right thing in every case... but isn't that the whole point of the abstraction layer? Where do we start? Are some backends more common than others? Best, Paul -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: New contrib releases
I have moved and released some c.c libraries into their new homes. * c.c.def and c.c.classpath are now combined under clojure.java.classpath and version 0.1.0 is available on maven central correction: c.c.def = c.c.jar * c.c.find-namespaces is now clojure.tools.namespaces.

Re: Feedback Request
Thanks. cljque looks interesting and might provide a nice abstraction for swing events. I made a little example of hooking a textbox to a ref: https://github.com/daveray/seesaw/blob/master/src/seesaw/examples/text_ref.clj Generalizing it might be tricky since data models (the stuff behind the ref) and user interactions (when should the ref be updated) vary so much. It would be easy enough, though, to have a helper function that wires together a widget and ref for simple cases.

As someone who spends a lot of time programming Swing, it's useful to me, but if some tweaks or changes would help others, I'd like to know. 2) How bad am I abusing Clojure and what could I do to improve it?

Re: Executing Future
the easiest way (i find) to test if something occurring on another thread has completed is using a latch: (deftest mohanr (let [latch (CountDownLatch. 1) service (Executors/newFixedThreadPool 10)] (doseq [x (range 1) :let [f (.submit service (proxy [Callable] [] (call [] (.countDown latch]] (is (= true (.await latch 1 TimeUnit/SECONDS)) its possible in your code the future isnt yet done, because you check immediately after submitting the task to the thread pool. hope that helps...

Re: swank-cdt: Using Slime with the Clojure Debugging Toolkit

Re: clojure.contrib.sql = clojure.java.jdbc - looking for feedback!
We've been using iBatis (http://ibatis.apache.org/) to compose sql fragments and map to java objects. iBatis has since forked from Apache to become mybatis (http://www.mybatis.org/). With iBatis, you can use XML to attach an identifier to sql fragments. You can build up sql expressions by referencing the fragments by id and also use simple logic. The XML is cumbersome, but seemed nicer than java strings to DRY out the sql. I was wondering if c.j.jdbc could provide some help in composing sql fragments, but I'm not sure what form it should take or if core clojure would suffice. We would have looked into ClojureQL, but it doesn't directly support Oracle. Would also be curious to know how people use clojure to compose sql fragments. -- You received this message because you are subscribed to the Google Groups Clojure group.

We would have looked into ClojureQL, but it doesn't directly support Oracle. Would also be curious to know how people use clojure to compose sql fragments. For Lobos I've written a compiler which transform an AST into SQL DDL statements. You can have a look at the compiler here: https://github.com/budu/lobos/blob/master/src/lobos/compiler.clj It's based on the legacy ClojureQL project, I've written some helpers but it's mostly using Clojure string facilities. So I'm not sure it would be a good idea to include such helpers inside c.j.j, outside the as-identifier function here: http://dev.clojure.org/jira/browse/CLJ-778 As for the new ClojureQL project, it would certainly be feasible to add support for Oracle, but I find it hard to work with its current simplified compiler.

Re: swank-cdt: Using Slime with the Clojure Debugging Toolkit
My problem was that I was including incanter, which depends on swank-clojure 1.3.0-snapshot, which was conflicting with 1.4. I deleted the swank-clojure 1.3 jar from 'lib' and it worked.

:dependencies [[clojure 1.2.0]]
:dev-dependencies [[swank-clojure 1.4.0-SNAPSHOT]

and created a file called config and placed it in .cake with the following
contents:
λ cat .cake/config
jvm.opts = -agentlib:jdwp=transport=dt_socket,server=y,suspend=n
I then pulled the deps with `cake deps`. My lib contains the following:
λ tree lib

ANN: Slamhound (for reconstructing ns forms)
So I just threw together a little tool to help with ns forms. I find often they accumulate a bunch of cruft over time where you no longer need a given :use or :require form. And sometimes you don't feel like finding exactly where on the classpath a given class is. Or maybe you're too lazy to type it; whatever. Slamhound helps with that. (ns my.namespace some doc string) (defn -main [ args] (pprint args) (io/copy (ByteArrayInputStream. (.getBytes hello)) (first args))) Look at that; all bare, missing all kinds of necessary stuff. Disgraceful. Release the hound! $ lein slamhound src/my/namespace.clj (ns my.namespace I have a doc string. (:use [clojure.pprint :only [pprint]]) (:require [clojure.java.io :as io]) (:import (java.io ByteArrayInputStream))) Tada! (also featuring Emacs integration: M-x slamhound) Enjoy: https://github.com/technomancy/slamhound -Phil -- You received this message because you are subscribed to the Google Groups Clojure group.

B) I just want to call my 'commands/add' function with a map and 'teal'

Re: Error with eval syntax-quote PersistentArrayMap
Hey Kevin, thanks for getting back to me.
The splice is 'etal' (which is null). I should have excluded it for
clarity. What you're actually seeing is the map being unquoted:
user= `(commands/add *~processed* ~@etal)
(commands/add {:tag :user, :username stub ... }) ;; 'etal' does not show
up in what gets evaluated - ** first in this list is a function
Now, if I try to eval that, I get the said error.
user= (eval `(commands/add *~processed*))
java.lang.IllegalArgumentException: Wrong number of args (3) passed to:
PersistentArrayMap (NO_SOURCE_FILE:324)
And I had tried macroexpand (here and in the containing function), and got
the same error:
user= (macroexpand (eval `(commands/add *~processed*)))
java.lang.IllegalArgumentException: Wrong number of args (3) passed to:
PersistentArrayMap (NO_SOURCE_FILE:324)
You're right that the repl is using the map as a function. But I don't
understand why when 'commands/add' function was the first thing in the
return list. And macroexpand is yielding the same error . This is what had
me so perplexed. Thanks again for the feedback. It's something small that
I'm missing.

Merging two maps based on ids
Can someone help me write a merge function between two maps? My problem
is as follows:
I have original data in a map:
(def data-orig
'({:id 2 :a2 34 :a3 76 :a4 87},
{:id 3 :a2 30 :a3 38 :a4 39},
{:id 5 :a2 67 :a3 32 :a4 38},
{:id 4 :a2 10 :a3 73 :a4 38},
{:id 7 :a2 84 :a3 86 :a4 63}))
Then I have override data:
(def data-override
'({:id 2 :a2 5534 :a3 5576 :a4 5587},
{:id 3 :a2 5584 :a3 5586 :a4 5563},
{:id 12 :a2 5593 :a3 5512 :a4 5539},
{:id 13 :a2 5509 :a3 5539 :a4 5592}))
The result should be a merge of the two with the following conditions:
If the id is the same, should override the original data. If id is not
present in original then it should be added. The result should be:
'({:id 2 :a2 5534 :a3 5576 :a4 5587}, ;overriden
{:id 3 :a2 5584 :a3 5586 :a4 5563}, ;overriden
{:id 5 :a2 67 :a3 32 :a4 38},
{:id 4 :a2 10 :a3 73 :a4 38},
{:id 7 :a2 84 :a3 86 :a4 63},
{:id 12 :a2 5593 :a3 5512 :a4 5539}, ;added
{:id 13 :a2 5509 :a3 5539 :a4 5592}) ;added
Thanks for your help.

Re: Error with eval syntax-quote PersistentArrayMap
Oh sorry, were the colors off? Let's try this.
The map was actually unquoted. 'etal' (which was null) was unquote-spliced.
I excluded it for clarity:
* user= `(commands/add ~processed) *
* result= (my-function my-map) ;; ** first in this list is a function
*
Now, if I try to eval that, I get the said error.
* user= (eval `(commands/add ~processed))*
* result= java.lang.IllegalArgumentException: ...*
And I had tried macroexpand (here and in the containing function), and got
the same error:
* user= (macroexpand (eval `(commands/add ~processed)))*
* result= java.lang.IllegalArgumentException: ...*
You're right that the repl is using the map as a function. But I don't
understand why when 'commands/add' function was the first thing in the
return list. And macroexpand is yielding the same error . This is what had
me so perplexed. Hopefully this reads a bit better.

{:id 7 :a2 84 :a3 86 :a4 63}))
Then I have override data:
(def data-override
'({:id 2 :a2 5534 :a3 5576 :a4 5587},
{:id 3 :a2 5584 :a3 5586 :a4 5563},
{:id 12 :a2 5593 :a3 5512 :a4 5539},
{:id 13 :a2 5509 :a3 5539 :a4 5592}))
The result should be a merge of the two with the following conditions: If
the id is the same, should override the original data. If id is not present
in original then it should be added. The result should be:
In the trivial case, you can use clojure.core/merge. Merge takes a
variable number of maps and merges them together. If there is a
conflict with keys, it will give preference to the latter map in left
to right order.
But in your case, you can write a trivial function that removes the
common maps from data-orig first and then does a merge -
(defn merge-override [merge-key override orig]
(let [keyset (into #{} (map #(% merge-key) override))]
(apply merge override (remove #(keyset (% merge-key)) orig
(merge-override :id data-override data-orig)
; = ({:id 7, :a2 84, :a3 86, :a4 63} {:id 4, :a2 10, :a3 73, :a4 38}
{:id 5, :a2 67, :a3 32, :a4 38} {:id 2, :a2 5534, :a3 5576, :a4 5587}
{:id 3, :a2 5584, :a3 5586, :a4 5563} {:id 12, :a2 5593, :a3 5512, :a4
5539} {:id 13, :a2 5509, :a3 5539, :a4 5592})
;; pprint -
;; ({:id 7, :a2 84, :a3 86, :a4 63}
;; {:id 4, :a2 10, :a3 73, :a4 38}
;; {:id 5, :a2 67, :a3 32, :a4 38}
;; {:id 2, :a2 5534, :a3 5576, :a4 5587}
;; {:id 3, :a2 5584, :a3 5586, :a4 5563}
;; {:id 12, :a2 5593, :a3 5512, :a4 5539}
;; {:id 13, :a2 5509, :a3 5539, :a4 5592})
Hope that helps.

I'm curious, what are your requirements for native dependencies? I have never needed them, so I've relied on contributors and external plugins because I don't know what's needed. But if it's a blocker for some it could get merged into Leiningen itself. I've looked at the plugin and it seems pretty simple.
