In a broader sense, it's because Clojure was designed to embrace the underlying
runtime. As well as eliminating problems with leaky abstractions (as others
have pointed out), it also encourages post to other runtimes like the CLR and
JavaScript (clojurescript)

Hi,
I tried out a double quoted string parser in parsatron. I'd appreciate it
very much if someone could review it and let me know if it looks okay.

(p/defparser optional [p default-value]
(p/either (p/attempt p) (p/always default-value)))
Ok, so i'm thinking about such one-shot detachable input pipe channels...

Thank you very much Phillip for the tip - #(#{\ \\ \n \r \t} %)) ;; =

I use the escape-map to get the value of various escape sequence - for
example, I want to transform \n in the input text to \newline.

Hi All,
I am new to clojure and have been working with the language for the
past one week. I have got a basic hold of the constructs in clojure. I have
been programming for 4 years in C# now. One thing I am not able to
comprehend is how clojure programs are structured. In an OO world, I
Reagent, a minimalistic interface between React.js and ClojureScript, is now at
0.3.0.
The new release adds a couple of bugfixes, and async rendering. Read more here:

The project page is here:

I suggest you check this out:
https://github.com/jimpil/MultiSnake/blob/master/src/multi_snake/core.clj
It is within the LOC you asked and shows a complete snake-game. It has
been adopted and extended from the book Programming Clojure, to handle
2 snakes and some other stuff like dying when
(defn index-filter [pred coll]
(when pred
(for [[idx elt] (indexed coll) :when (pred elt)] idx)))

but I don't know why use when pred in the code,
and why (index-filter {\a \b} abcdef) doesn't work?

Hi Aravindh!
I've found the leiningen source very clean and well organized. It was one
of the first production products that I read through, and it has the
benefit that you're probably familiar with what it does and will probably
want to extend or configure it.

a vector is a function of its indices
a map is a function of its keys
a set is a function of its elements
does this help at all?

Is it possible to use 'repeated with a dynamic size if the length-defining

I don't get a stack overflow error, I get ArithmeticException integer
overflow. It's trying to compute an integer that's too big. Try changing

For various reasons, and despite the convenience of anonymous functions,

I'd like to have by-name parameter binding, but that's another story.)
For example, the following seems to work:
My usual approach is to use a macro that expands to the appropriate (it) forms,

As Mars0i says below, this is due to concat; more specifically, since map,
partition, and concat all return lazy sequences, with recursion you are
constructing a large chain of nested lazy sequences, as explained here:

But maybe it comes from css? It does look a bit like a clearfix (or somesuch)
