Re: A forum for Clojure...?

It's a little different for language communities. More experienced developers will tend to use mailing lists or IRC. Also, I think stackoverflow is quickly become the go-to place for beginners to a language. On Tue, Mar 5, 2013 at 2:14 PM, BJG145 wrote: > I don't see it as an experience thing. T

Re: Clojure - Python Style suggestion

Again, I don't think it will help attract new users, at least not the way we want. Parentheses are an important part of the language and it's not something a beginner can just pick up later. If they're scared of parentheses now, they'll be scared when they try to jump from this paren-lite syntax to

Re: Clojure - Python Style suggestion

Sergey's example code seems to have arguments to a function happen on the same line while new function calls appear on new lines. So: filter smaller xs ...would be the equivalent of filter(smaller(xs)). Anyway, I agree that parens don't add any more clutter. Having to *always* have all the arg

Re: Is there any reason to make different file extension (clj and cljs) for Clojure and ClojureScript?

While Clojurescript aims to be close to Clojure, they're still different languages, with entirely different compilers. Much of the Clojure toolchain uses the extension to figure out how to compile a given file. Otherwise, as far as I know there's no reasonable way to tell apart Clojure code from Cl

My guess is that it's useful in the core functions which are more heavily used. Otherwise you're getting into premature optimization if you use it in any of your own functions without profiling it first. On Tue, Oct 2, 2012 at 4:18 PM, Balint Erdi wrote: > Makes sense but why don't we have it in

Re: Why IPersistentList doesn't extend ISeq?

First, IPersistentSeq is the interface, PersistentSeq is the actual class. If you look at it a little more closely, PersistentList extends ASeq, which is an abstract class. ASeq implements the ISeq interface. So PersistentList does implement ISeq through its parent class. https://github.com/cloju

The name given an anonymous function can only be used within the scope of that function. This will work: (fn my-func1 [x] (my-func x)) ; Leads to infinite recursion, of course This won't work because my-func1 is called outside of the function's lexical scope: (fn my-func1 [x] x) (my-func1 100)

Re: Why Clojure map literal creates an instance of array map?

It's not dependent on whether it's a literal but on the size of the map, 8 key-value pairs is the threshold. This results in a PersistentHashMap (class {1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9}) => clojure.lang.PersistentHashMap This gets you a PersistentArrayMap (class {1 1 2 2 3 3 4 4 5 5 6 6 7 7

Re: what is "js/" in clojurescript?

A quick explanation is that functions/other javascript objects that otherwise exist in the global namespace (ie. document, console, window) are accessed through the js/ in Clojurescript. This is a JS-specific thing and therefore you don't find js/ in regular Clojure. However, doing the form (MyCla

Re: Opposite function to cons, but in terms of construction, not destruction.

Conj (http://clojuredocs.org/clojure_core/clojure.core/conj) does what you need for vectors. It's behavior depends on the type of collection passed, so if you did: (conj '(1 2 3) 4) you would end up with '(4 1 2 3). For vectors it appends to the end of the list, for lists the beginning. On Sat,

Re: principle of least surprise

It's because functions such as reduce, map, reverse, etc. only work on sequences, so they have to call seq on that argument. Strings just happen to be seq-able but calling seq on one returns a list of characters, so the result is one too. Reverse always returns a sequence and strings aren't technic
