Clojure never changes the types of things you're using I think you'll find that clojure doesn't change types, except where required, mostly for boxing. Clojure 1.2 would construct a new Integer around an int when required. Clojure 1.3 constructs a new Long around an int instead, because rich has decided he prefers longs and doubles to ints and floats.

Will clojurescript get in-ns and load?
Is it planned for clojurescript to get *in-ns* and *load*. These would be most useful for code modularisation (see thread Reuse of generic Clojure/ClojureScript code?)

Re: Reuse of generic Clojure/ClojureScript code?
If/when clojurescript gets* in-ns* and *load* the previously outlined solution could be improved. I could use load to include platform specific ports of intended core library capability into the generic files. This would mean that you would only need to require the generic file, regardless of platform. requiring or using a .x library would be used only where functionality was not planned or intended to be made portable. This would be very handy Is it planned for these functions to be developed? Cheers Dave -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Clojure 1.3 treatment of integers and longs
Thanks. I read through that and it didn't quite answer my question. To me it seems more logical that: 1. Clojure defaults to longs when you create a new number (with a literal 0, 1, etc) 2. You can create ints by doing (int 0) 3. Clojure never changes the types of things you're using I find Clojure's behavior of changing the types of primitive ints to longs highly unusual, and it is causing a lot of pain in upgrading Storm to 1.3. I don't mean to imply that the design choices made were wrong; I know that Rich et al put a lot of thought and work into these changes. But I would like to understand why changing the types of ints to longs is necessary instead of supporting primitive ints as well. -Nathan On Oct 18, 2:25 pm, David Nolen wrote: > 233 messages long thread from June > 2010,http://groups.google.com/group/clojure/browse_thread/thread/c8c850595... > > David > > > > > > > > On Tue, Oct 18, 2011 at 5:00 PM, nathanmarz wrote: > > Hey all, > > > I recently started upgrading Storm to Clojure 1.3, and I ran into > > various issues due to Clojure's treatment of integers and longs.

Clojure 1.3 treatment of integers and longs
Hey all, I recently started upgrading Storm to Clojure 1.3, and I ran into various issues due to Clojure's treatment of integers and longs. In particular, I have a situation like the following: 1. A Java object returns me an int. Let's call this value "v". 2. I put "v" into a map, and pass that map into a Java object 3. I get ClassCastExceptions when that Java object tries to read that Integer and instead gets a Long back The error arises due to Clojure's auto-coercion of primitive ints to longs. Auto-coercing ints to longs is prone to errors like I ran into, especially when interoperating with Java code. It becomes especially confusing when considering that "Integer" objects do not get coerced to "Long" objects. Also, if Clojure is trying to treat everything as longs, I don't understand why there's an unchecked-divide-int function and not an unchecked-divide-long function. What's the rationale behind all this? Why not support both ints and longs? I'm sure this has been discussed before, so feel free to point me to earlier discussions on this. -Nathan -- You received this message because you are subscribed to the Google Groups "Clojure" group.

I've tried: (import 'clojure.string) (import 'string) and (:require [clojure.string :as str])) The last one is from the documentation in the string.clj file embedded in the jar.

Re: What changed 1.2/1.3 to cause this program slowdown?
I'm not an expert on the topic, but the threadring example has some suspicious ^Integer hints on values that were integers in 1.2 and are longs in 1.3 (ie, they were created from numeric literals). The hints don't seem to be actually being used, so I don't think this has an impact, but perhaps mentioning it will help someone else find the problem.

I don't know what accepted etiquette is around doing such things in parallel with "regular" conferences, but I'd think good form would dictate that topics shouldn't "compete" with the scheduled talk. e.g. A ClojureScript mobile BOF probably shouldn't be scheduled opposite the announced ClojureScript talks.

Nobody wants inexact numbers, but one has to trade speed with exactness. And usually, you should refrain from using floating points at all, no matter if BigDecimal or Double. Clojure has rationals, so unless you have to use java.lang.Math's functions or PI and E constants, you can possibly do all calculations with rationals, and when you really need a float, use (bigdec my-rational) to coerce it to a BigDecimal. > That's why I was hoping for a global default for reading decimal > numbers as BigDecimal instead of IEEE floats or doubles.

Re: Is there a reader setting support BigDecimal by default?
I'm looking to avoid qualifying every number that has a decimal point with an M. For the "business" applications I've built over the last 25 years (credit card processing, healthcare claims, loans,etc.), there's never been a situation where inexact numbers were appropriate. That's why I was hoping for a global default for reading decimal numbers as BigDecimal instead of IEEE floats or doubles.

Re: clojure.string no namespace error
If you do a (require 'clojure.string) then all vars will be accessible as clojure.string/... e.g.clojure.string/split-lines . You can use "use" to import the vars into the current namespane: (use 'clojure.string) This wil make available all vars from clojure.string in you current namespace (e.g. user). The later syntax is for use within the macro "ns" to declare a namespace, e.g. (ns user (:require [clojure.string :as str])) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

clojure.string no namespace error
Hi all, I've started to teach myself clojure recently, so apologies for a potentially stupid question. I'm using clojure-1.3.0.jar, downloaded very recently. I would like to use clojure.string/split-lines, but I cannot access the namespace. I've tried: (import 'clojure.string) (import 'string) and (:require [clojure.string :as str])) The last one is from the documentation in the string.clj file embedded in the jar. They all throw either a "java.lang.ClassNotFoundException: clojure.string" or a "java.lang.Exception: No namespace: clojure.string". Calling (all-ns) gives me a list of namespaces which does not include string, and (find-ns) doesn't find clojure.string either. Not sure what I'm doing wrong. Any pieces of wisdom?

Macro not working - newbie question
I just finished my first macro:
(defmacro defrecord-withstr [recordname include columns recordargs]
(let [ vv (gensym)
stato
(let [cols
(if include
columns
(vec(seq(clojure.set/difference (set recordargs) (set
columns)
]
(vec(interleave
(vec(map #(str ":" %) cols))
(vec(map #(symbol(str "(str (:" % " " vv "))"))
cols
))
)))]
`(defrecord ~recordname [~@recordargs]
Object
(~(symbol "toString") [~vv]
(reduce
#(str %1 " " %2)
~stato
)
)))
)
It should override the toString for records so that it prints just the
chosen columns.
If i do the macroexpand:
user> (macroexpand-1 '(defrecord-withstr Test true [a b] [a b c d]))
(clojure.core/defrecord Test [a b c d] java.lang.Object (toString
[G__7830] (clojure.core/reduce (fn* [p1__7524__7526__auto__
p2__7525__7527__auto__] (clojure.core/str p1__7524__7526__auto__ " "
p2__7525__7527__auto__)) [":a" (str (:a G__7830)) ":b" (str (:b
G__7830))])))
When I try to execute that everything works OK:
user> (clojure.core/defrecord Test [a b c d] java.lang.Object
(toString [G__7830] (clojure.core/reduce (fn* [p1__7524__7526__auto__
p2__7525__7527__auto__] (clojure.core/str p1__7524__7526__auto__ " "
p2__7525__7527__auto__)) [":a" (str (:a G__7830)) ":b" (str (:b
G__7830))])))
user.Test
user> (def tt (Test. 1 2 3 4))
#'user/tt
user> tt
#:user.Test{:a 1, :b 2, :c 3, :d 4}
user> (str tt)
":a 1 :b 2"
But when I call this directly, it doesn't work:
user> (defrecord-withstr Test2 true [a b] [a b c d])

It must be some namespace issue, but I just don't understand what is
the problem...
