You can't. A macro cannot depend on runtime information

Here is an update to my log viewer in clojure. It mostly works on
win32 and I hope to get it past an alpha release., but if you are
interested in gui applications in clojure, all source is provided.

If you run it, I will be happy.

This here works fine when I pass a literal collection:
(defmacro let-coll
[coll & body]
`(let ~(vec coll) ~...@body))
user=> (let-coll [a 11 b 22] (list b a))
(22 11)

I was experimenting with how binding behaves within a loop and found
some inconsistent results:
(def y 0)
(loop [x 0]
(println "x " x)
(binding [y (inc y)]
(println "y " y)
(if (< x 10) (recur (inc x)
The printed lines are what you'd expect:
x 0
y 1
x 1
...
x 10
y 11
But if

Thanks for pointing that out.
I notice this is actually on the reader page - apologies for not

Chouser -
Can you describe definline and how that differs from defmacro? I'm
not sure I understand it from reading the docs.

Awesome, thanks for the quick answer. I think that it'd be a useful
thing to add to seq-utils or something. :)

how about something like:

A maybe related newbie question.
How common is it for Clojure to separate the two implementations into
different libraries?
For example, in an application I create one lib that contains just the
data for the app (app.data)
and two other libraries that provide the functions on the data
(app.d

The usual technique in Common Lisp is

(1 2 4)
You can improve readability by using #+:never or somesuch, but tha

Hi,

I have defined a function, typed \sr -> REPL started... the fn is not

Sounds like a good application of the broken window principle to me.

This is so trivial from a technical standpoint I'm embarrassed to

then generating output for all of them in an unusual fashion. In the

Heheh, three times slower but gives the wrong answer--maybe not a

I'd misread the way the last if statements work in the Python

Hello,
Can this construct handle higher-order functions?
(I mean a function with named arguments as an argument to another
function).
It seems quite difficult to do a function dependent transformation on
the call site when the function is unknown.
Best regards,
Nicolas.

Thanks. Your code is definitely much more idiomatic Clojure - and 3X
faster. The lcs function does exactly what it is suppose to, but the
backtrack-all function only returns the first LCS found(for the
strings "AATCC" "ACACG" => ("ACC"), whereas the Python version returns
all the LCSes found (for
