Re: So many clojure implimentations?

I also do not think that this is a bad thing. First, I don't see the many implementations of lisp as a "mistake". They are all bound together by the language standard, which is good enough for compatibility, meaning that most of the time you won't need to use implementation specific features. A

Status of Generic Functions (a la lisp)

Hi, I'm looking for fast lisp style generic functions in clojure. In other words: multimethods that dispatch on the java type. A search on the web revealed little, since protocols and multimethods always show up. I have also seen some old discussion in this group on the topic, but I couldn't fi

Re: Status of Generic Functions (a la lisp)

The keyword here is speed. Multimethods are not fast. They don't use the JVM for dispatch (as far as I know). Protocols are fast. That's the reason for their existence. I want to find out whether there's some effort invested in making fast multiple dispatch in Clojure (and how else can it be bu

Do you like the Clojure syntax?

Hi, I'm curious about the general opinion on the Clojure syntax, whether people actually like it or just use it because it provides macros. So I would like to ask you to participate in a poll. Thank You. Here's the link: https://docs.google.com/forms/d/1GSgfkeThpUYlgFVzhhNIgA1JbTilu6S9eudq_Sbxl

doseq with index

Hi, Is there an elegant way to use a doseq or for and also get an index to use? I find myself using map-indexed in these cases, and I prefer more the for constructs. (doall (map-indexed (fn [i x] ;do stuff with side effects using i and x ) a-lazy-seq)) Chee

core.async vs continuations

Hi, Pardon the ignorance, I was just rewatching Rich Hickeys talk about core.async, and realized that the await call is actually a continuation (like call/cc from scheme). And if I am not mistaken, you can't implement call/cc with macros, so I suspect there is a difference, but I fail to see i

Re: Clojure <--> LISP

Hi, Here's how I would summarize it: - Common Lisp = big standard, very old, unlikely to change in the future, complex and powerful object system, several implementations, almost all mature and efficient, has some quirks with historical roots - Scheme = small standard, also very old, changing bu

browser repl for clojurescript with counterclockwise

Hi, Is it possible to have a browser based repl for clojurescript with counterclockwise? I tried to set up one as described on the clojurescript site, but my impression was that ccw is not able to send forms for evaluation. Cheers, Razvan -- You received this message because you are subscrib

Re: Clojurescript Error: Undefined nameToPath for goog.ui

Hmm, I'm stuck again. :) I don't know why, but it seems that building the project with * lein-cljsbuild* does not accept :import. Here's the code: (ns habarnam (:use [domina :only [xpath]]) (:import [goog.ui [Button]]) And here's the compilation error: Compiling ClojureScript. Compiling
