Dear all,
I am happy to announce the public availability of clj-iter, an Iterate-
like iteration macro. It is free (available under the terms of MIT
license) and can be found on GitHub: http://github.com/nathell/clj-iter
The design goal was to keep it as simple as possible, and make it
blend well with the rest of Clojure. In
contrast to cl-loop, which uses mutable bindings, clj-iter has a
functional flavour, and macroexpands to the kind of code you would
write manually using loop/recur. It is also very simple, having a
fraction of Iterate's functionality, but I hope even the little there
is will be sufficient in many cases.
To avoid citing the entire README blurb, I'll just give you some
examples:
(iter (for x in [31 41 59 26])
(for y from 1)
(collect (+ x y)))
==> (32 43 62 30)
(iter (for s on [1 2 3 4 5])
(for q initially () then (cons (first s) q))
(collect (cons (first s) (concat (take 2 (rest s)) (take 2
q)))))
==> ((1 2 3) (2 3 4 1) (3 4 5 2 1) (4 5 3 2) (5 4 3))
Please let me know whether it is of any use to you. Feedback, and
especially patches, are more than welcome.
