Hi.
You might consider reading Peter Seibel's excellent Practical Common Lisp
which has some nice macro-work in it. If after that you're still hungry for
more, consider Let Over Lambda by Doug Hoyte.
Admitted, both cover Common Lisp, but the differences will not keep you from
getting a deepe
Hmm, I think the maven convention will start to make sense, somehow :
src/main/java/
->
src/main/java/
src/main/clojure/ ; clojure only code (jvm that is)
src/main/clojurescript/ ; clojurescript only code
src/main/clojure&script/ ; shared by clojure or clojurescript : no
bounty, but better name
I managed to do it.
The problem is that we need to use the function set in a goog.net.Cookies
object.
There is already such an object, which is called goog.net.cookies, see the
bottom of the source file:
/**
* A static default instance.
* @type {goog.net.Cookies}
*/
goog.net.cookies = new goog.
Thanks to all! You have helped a lot!
Also I will consider reading "Practical Common Lisp".

I use Base64 encoding a lot and the slow implementation is hurting a
lot. It's slower than Sun misc encoder/decoder
and that one is very very slow. I was using Sun's implementation a bit
and it took 80 seconds to encode a 56 MB file.
Then I found this: http://migbase64.sourceforge.net/

This is already possible, if you're using leiningen:
put the file in src/util/ and compile, you can now call it as usual.

Hi,
may I ask an heretic question?
When there is a fast migbase64... why not just use that one?
It was always promoted to use existing Java libraries where it made sense.
Or is clojurescript now changing this stance?
Sincerely
Meikel

Thanks Jonathan! That's it exactly. I had seen goog.net.cookies
(lowercase) and didn't realize it was an object on which to make the
set call. I thought in was another namespace in which to make the
function call, thus I had been writing:

nice wrappers around the messy java crypto bits I think could provide a
significant win. I have had to do this several times now
Hi,
I want to instantiate a record, but having the record type as value at
runtime.
Example:
(defrecord car [year manufacturere])
(defrecord bike [year manufacturere])
(defrecord boat [year manufacturer])
I want to do (new stuff 1982 "Mercedes"), but having the record type
kept in the variable "
Assuming you want to do things with the record later, why not just
create it in the let binding
(let [foo (->car 1982 "Mercedes")]
...)
or
(let [foo (car. 1982 "Mercedes")]
...)
or even
(let [foo (map->car {:year 1982 :manufacturer "Mercedes"})]
...)
or if you must
(let [foo #user.car{
is it ->record just a shortrand for record.?

Wow, that was fast. Thanks.
This could work but only partially.
(let [stuff car]
(new stuff 1982 "Mercedes")
(new stuff 2001 "Seat")
...)
I could take advantage of the fact that records are maps:
(let [stuff (car. 1982 "Mercedes")]
... use Mercedes...
(assoc stuff :year 2001 :manufac
Just wanted to add the Apache commons codec has a base64
encoder/decoder. With a quick test I was able to encode a ~100MB file
in 2.3sec. Example code below:

(import '[org.apache.commons.codec.binary Base64OutputStream])

You can't pass car. around at runtime because it is a

when reading/parsing and 5x when creating a JSON string.

Sure, I can use that file. This DIY attitude doesn't benefit the

the problem is in Reflector.java and the call to Class/forName is

->foo is new in 1.3. I'm surprised so many people are recommending it
without mentioning that. ->foo is like foo., except that it's a real
clojure function and as such can be passed as a function; you can call
apply on it; and so forth.

An excellent JVM library to use as base is Jackson:

It would be wonderful to see a Clojure-friendly version of it: having it
create Clojure-specific structures from JSON, and also recognizing Clojure
deftypes for serialization. The streaming API is friendly enough t

Cheshire looks great, thanks for the tip!
I wonder, then, what's the OP's problem? I think it's good to have a
lightweight, 100% Clojure version of JSON in contrib. A lighter weight is
often a higher priority than performance. I think both approaches have their
place.
In the Java world, too, t
As I mentioned in my previous email, my problem isn't really picking a
JSON implementation for my own needs, but rather when I use a library
that uses a slower implementation. If I wanted to use clutch for
couchdb access and didn't pay too much attention as to what leiningen
pulls in, I wouldn't kn

Is there any support for this at the moment?
My only comment would be that it is quite handy to know that you have
imported code that might be platform specific.
It also seems reasonable that pure clojure code might be used by the .net
version.

In my opinion, the situation is not clear cut:
I might want a slower but more portable library if porting clutch to
clojurescript.
(I read that someone has this working...)
I might just want a lib that works if moving to .net in the short term but
optimise with a faster library later.

Hi,
slf4j comes to mind. Have a standard API which is provided by the different
libraries. If you were targeting clojurescript you'd specify the portable
library. For a server application running on the JVM you'd specify a fast
Jackson-based implementation. This leaves the choice to the user of
