There is a pretty wide range of ways to solve problems in Clojure,
arguably more so than Python. This isn't exactly how I'd code it, but
there's nothing so egregious in it that I'd call it un-idiomatic. I'd
probably use keywords rather than strings. I'd probably use lists

I appear to have solved the problem. Actually my main development is
using clojure box which is a windows clojure development enviroment
that runs in slime/emacs. It appears that you need to load the native
files for your operating system to the library path. I'm not sure how

The following is an interview with Rich Hickey where he answers your

Thanks John. I mined contrib for java-util/file and duck-streams for
several functions as well.

Tomorrow I'll add a bunch more file functions and tests.

Oops, you're right; I was thinking about something else. And I have
another mistake in my function too—I meant:
(defn transform-map [f a-map]
(into {} (map #(vector (key %) (f (val %))) a-map)))
It's unfortunate that it's not in any standard library yet. I've used

The short answer is no.
This came up on the dev list here:

Oh, and I'd write the function slightly differently
(defn transform-map [f a-map] ...)
The f implies a mapping operation. pred implies a filter operati
Is there a function in the standard libraries that's equivalent to
this:

(into {} (map (comp pred val) a-map)))

will actors actually do the queued function w/in a reasonable
timeframe? i don't think there are any guarantees of it so if one is
hoping to get really nicely periodic behaviour...
Represent each cell as a row number, column number, and a set of
possible digits that can go in that cell.
Create a map that generates a keyword for the sector name from the row
and column numbers.
You're going to write a recursive function that processes a sequence
of cells that still need to be

Another thought occurs: "depend" could be shortened to "dep":

One variation of the above I forgot to mention:

Hi folks,
I'm working on a Clojure package manager called Capra, and I need some
opinions on the syntax for specifying dependencies. The most basic
system I've come up with is:

I need "durable data" that interacts well with the STM too. I describe
a system that works well for a specific use-case:
All data is stored in the persistent datastructures that clojure
provides and changes are protected via refs as one would expect --
standard idiomatic clojure.

These are all very good questions, but they are legal questions,
not technical questions, let alone Clojure questions.
The sad thing is that it really is not possible to give you a definite

Opinions differ. The answer might depend on the governing law of the

I've watched some Clojure screen cast where Rich Hickey mentions that
initially Clojure was co-developed for both platforms simultaneously.
But then it became too hard and he has dropped .NET support.
Out of curiosity, why JVM has won the contest :-)?
