Re: Is anyone relying on the js* special form?
2012/9/25 Brandon Bloom snprbo...@gmail.com clojurescript gives no access to javascript's delete operator. There is a js-delete macro in core. It uses the same form as your proposed adel form. Oh, beg your pardon, I have overlooked that. I have to admit, a del! form for deleting advanced-optimized properties is arguably less important, since you can't reflect on them anyways. -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] Immutant 0.4.0 released
Trying to stick to a bi-monthly release cycle, we announced version 0.4.0 today: http://bit.ly/immutant040 In a nutshell, Immutant is an application server for Clojure. It's an integrated platform built on JBoss AS7 that aims to reduce the inherent accidental complexity in real world applications. New features in this release include durable topic subscribers and representing JMS message properties as Clojure metadata. We also sped up deployments a bit and added some convenient options to the lein plugin, e.g. $ lein immutant deploy --context-path / --virtual-host some.host.com More details available from the above link.

Behavior of (eval) in different namespaces
Does anyone know what's going on here? user= (let [a 1] (eval 'a)) 1 user= (ns another-ns) nil another-ns= (let [a 1] (eval 'a)) CompilerException java.lang.RuntimeException: Unable to resolve symbol: a in this context, compiling:(NO_SOURCE_PATH:41) If let-bound locals were treated as symbols in user, this behavior would be understandable (though I don't know why on earth let would be implemented in such a bizarre fashion). Anyways, locals are *not* symbols in user, as you can see: user= (let [a 1] user/a) CompilerException java.lang.RuntimeException: No such var: user/a, compiling:(NO_SOURCE_PATH:1) I started tracing through the code for (eval) in Compiler.java, but got lost at the point where it wraps (let) forms in (fn [] ...) before evaluating them... BTW, if you convert the above let to an equivalent lambda expression, the behavior is consistent between user and other namespaces: user= ((fn [a] (eval 'a)) 1) CompilerException java.lang.RuntimeException: Unable to resolve symbol: a in this context, compiling:(NO_SOURCE_PATH:6) -- You received this message because you are subscribed to the Google Groups Clojure group.

Setting up Dev Environment
Getting your machine set up to write Clojure is humorously easy. First,
the good stuff:
$ brew install clojure
$ brew install leiningen
Then, you'll want to get the VimClojure plugin. This enables syntax
highlighting, file type recognition, etc. Assuming you're using Pathogen:
$ cd ~/.vim/bundle # = or wherever you keep your vim plugins
$ git clone https://github.com/vim-scripts/VimClojure
One nifty feature of the this plugin is colorizing your parenthesis to help
you keep track of what's going on. To enable, add this to your .vimrc:
Settings for VimClojure
let g:clj_highlight_builtins=1 Highlight Clojure's builtins
let g:clj_paren_rainbow=1Rainbow parentheses'!
That's it! To start a project, run
$ lein new {project name}

newbie question regarding maps
I am playing around with maps and using wish lists as a learning tool. I
have a list of items in wish lists like this:
user= items
[{:name Item 1, :cost 20.0} {:name Item 2, :cost 40.0}]
user= wiggle-items
[{:name Wiggle 1, :cost 20.0} {:name Wiggle 2, :cost 40.0} [:name Item
3 :cost 10.0]]
user= (def wish-lists [
{:name WL1 :items items}
{:name WL2 :items wiggle-items}
]
)
#'user/wish-lists
user= wish-lists
[{:name WL1, :items [{:name Item 1, :cost 20.0} {:name Item 2, :cost
40.0}]} {:name WL2, :items [{:name Wiggle 1, :cost 20.0} {:name Wiggle
2, :cost 40.0} [:name Item 3 :cost 10.0]]}]
---
I now want to add an item to one of the Wish Lists but am struggling with
assoc and assoc-in (which seems to be the one I need).
---
user= (def new-wi (conj wiggle-items [ :name Item 3 :cost 10.0 ]))
#'user/new-wi
user= (assoc-in wish-lists [:name WL1] [:name WL1 :items new-wi])
IllegalArgumentException Key must be integer
clojure.lang.APersistentVector.assoc (APersistentVector.java:312)
As you can see the REPL gives me an error stating that the keys must be
Integers. Is that right? Or is my call process faulty?
Thanks in advance for your support.

Does Clojure support efficient coroutines?
Hi, It seems the JVM doesn't provide any support for coroutines, generators, light-weight threads, or non-reusable continuations. I can't find any mention of coroutines in the docs, so I'm guessing Clojure doesn't have them due to the lack of JVM support. Is that correct?

Transactional memory design rationale
Hi, I have two questions about the reasons behind the design of Clojure's software transactional memory (STM): (1) Why is snapshot isolation the default rather than linearizability? For those who don't know, the difference between the two guarantees is that snapshot isolation requires all reads to occur at a read point and all writes to occur at a later write point, whereas linearizability additionally requires those two points to be one and the same. Most of closure's design seems to prefer correctness over efficiency, but this decision places efficiency over correctness. Why not make the safe behavior of the current ensure the default with the one-character name and leave the more efficient but harder to understand deref behavior as something available when optimizing hot code? (2) Was the _principled_ form of open nesting in the paper titled Open Nesting in Software Transactional Memory ( http://www.cse.msu.edu/~cse914/Readings/openNestingInSoftwareTransMemory-ppopp07.pdf) considered for clojure's STM? That paper (which I have nothing to do with) deals with the issue of an STM sometimes thinking two operations conflict due to conflicting reads and writes even though from the perspective of abstract data types the transactions shouldn't conflict, For example if one transaction modifies key X in a hashmap and another modifies key Y those transactions shouldn't conflict unless those two hashmap operations are executing at the same time and don't execute correctly. If the two operations occur at different times then those two operations needn't conflict, even if they happen to both write the same data e.g. incrementing a counter of the number of keys in the table. This sort of principled open nesting solves the problem that clojure's commute does but also handles cases when an operation commutes with _some_ other operations but not _all_, e.g. two hashmap writes to different keys don't conflict with each other but writes to the same key do.

odd behavior with non-greedy quantifiers in ClojureScript regular expressions
I'm just starting with ClojureScript and I've noticed a couple odd behaviors with regular expressions, which I assume are bugs. The first has to do with non-greedy (reluctant) quantifiers. The following regexes work fine: ClojureScript:cljs.user (re-matches #a?b? a) a ClojureScript:cljs.user (re-matches #a?b? b) b as does this: ClojureScript:cljs.user (re-matches #a??b? b) b but the following doesn't: ClojureScript:cljs.user (re-matches #a??b? a) nil It does work in regular Clojure: user= (re-matches #a??b? a) a I understand that Clojure uses Java regexes and ClojureScript uses JavaScript regexes. I've never really used JavaScript, but my understanding is that it supports non-greedy quantifiers. The other issue is that re-seq in ClojureScript hangs on certain inputs: ClojureScript:cljs.user (re-seq #a? a) no response Thanks, David -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojure : a good start for non-programmers?
Yes (definitely not brainfuck), but I would recommend not starting with something with ugly syntax like C, C++, Perl, or PHP (and many others, I'm sure) these days. Something friendlier and dynamic like Clojure is an excellent idea. Two alternatives I'd give a non-programmer are Python and Ruby. Clojure gets a bonus for not being object-oriented, in my opinion (you don't even have to learn what that means--except for java interop, ha). The syntax for Clojure/Lisp can be hard for some newbies, due to the massive parentheses trails, but with proper editor assistance, you can surpass that. http://xkcd.com/297/ I recommend The Joy of Clojure, although it might be rough for a newbie after a couple of chapters, it's still excellent. You can always go back to it, if it gets too difficult to follow. There's also http://www.4clojure.com/ , and the clojure koans that can get you some hands on practice. Good luck!

Well, you can eliminate the implementation of Keyword.hashCode() as an
explanation for what you're seeing:
public final int hashCode(){
return hash;
}
So, that leaves two possibilities: (1) You're doing something very
unusual in your code, which we can't say since you haven't showed us
any actual code. (2) You're misusing visualvm or misinterpreting the
results.
I'm guessing 2.

The challenge of learning Clojure as a first language is that: 1. Some of the best learning resources for Lisp-like languages are books that use the Scheme dialect of Lisp. If you know what you're doing, you can translate all those ideas to Clojure, but the correspondence might not be so obvious to a beginner. 2. Clojure sits on top of Java. You can mostly think in Clojure, but every once in a while, it really helps to understand Java's strengths and quirks and understand how interop with the host system affects Clojure's design. 3. Debugging and other sorts of language tooling lag behind those of languages that have been around much longer. I'm sure there must be success stories of people who picked it up as a first language, but I personally feel I would not be as strong a Clojure programmer had I come to Clojure without significant prior experience in both Scheme and Java. -- You received this message because you are subscribed to the Google Groups Clojure group.
