Chas,
thank you for the explanation, it confirmed my vague thoughts I had after
quick review of Clojure source code and inspection of values in prototype
maps before and after the change.
I understand the difference, however I think there are three points to
consider from Clojure design point
I have this list in python:
cc = list()
for i in range(256):
cc.append(ctf.GetColor(float(i) / 255.0))
And I would know if this is correct conversion in clojure?
(def cc
[(for [i (range 256)]
(.. ctf GetColor (/ i 255.0)))])

Take a look at my pyclj library, which could dump/loads clojure literal
to python data structures.
https://github.com/sunng87/pyclj
You can dump you cc and use read-string to load it into clojure.
import clj
print clj.dumps(cc)

It is correct in the sense that it will do the same thing. If you have a
collection and need to calculate
a value for every element in it and re
I think versions with `for` is a hell more readable.
I vote for this:

Dan,
Re: (2), yes, using higher-order functions effectively is a big part of
functional programming. But, no, passing a var to HOFs in every case instead
of dereferencing its value is not a good blanket policy. You need to have a
clear notion of what you want to happen and what the contract o
Funny,
We implemented something similar using zookeeper (thanks to David for
zookeeper-clj). We store data as Clojure expressions. This was a move to
have a cluster unified view of configuration data and go away from alien
representations (we used Yaml in several places).

Hey Everyone,
I've been using lamina channels to create queues to download files/web
pages in parallel. I'm using clj-http as my client as it supports proxies.
So basically I create a channel, then use map* to fetch process and queue
up pages in the channel. My fetch-url-with-proxy function, di

Hi there,
My current development environment is that: Sublime Text 2 editor with
the fabulous SublimeREPL plugin to be able to copy code into the Clojure
REPL.

functions or selected code to the REPL. It's supposed to be t
Hi,
I am looking for two seemingly simple operations which require adding
to the list:
(( 1 2 ) ( 20 30) (40)) 50 => (( 1 2 ) ( 20 30) (40 50))
and
(( 1 2 ) ( 20 30) (40 50)) 60 => (( 1 2 ) ( 20 30) (40 50) (60))
Basically it is appending an element as a list to the list
I guess you should use vectors, since you can't effectively add an element
to the end of list.

Yeah, this becomes much more straightforward using vectors.

once again thank you for very detailed explanation :) I have not seen all

Or even shorter, but maybe not as fast because it flattens the given
list, then pairs it up again. Thus it also assumes the resulting list
should consist ENTIRELY of pairs and singletons, not just the last or
penultimate element:
(fn [l x] (partition-all 2 (concat (flatten l) [x])))

Try clojure.string: http://clojuredocs.org/clojure_core/clojure.string
It's available in 1.3 and replaces clojure.contrib.string. You can
also access all methods of java.lang.String via java interop.

Hi all,
I was looking for a way to:
* encourage folks to write docs for their Clojure projects
* make usage examples available (like clojuredocs.org has, but for
general Clojure-related projects)
* help semi-standardize how Clojure projects are documented
So I made this:

This is a great initiative but so far it seems to focus only on the API
reference part of documentation.
I personally think that documentation guides are just as important [1].

It's a great initiative indeed, but I found the project pretty useless in
its current state. Forking the repo and sending a pull request just to add
an example is painful. Also, I can read rendered readme on github (and have
the source code at hand), so why go to another site?

One thing I forgot to mention: it'd be nice to have Marginalia support,
since it can be used not only for annotated source code, but also for
documentation with embedded tests (although, two-column layout doesn't fit
very well for this purpose, but it's another question).
