List quasi-quoting

2009-12-23 Thread Andreas Fredriksson
Hi, I'm prototyping a source translation framework in Clojure and I've run across a problem. I have a bunch of files with s-expression data and I'd like to define my own macro expanders for that data, like this: (defmacro defexpander [sym args body] `(let [fun# (fn ~args ~...@body)]

Here's a good start: http://www.google.com/search?hl=enq=site:github.com+clojure But the best plan is to start using clojure for real work, then contribute to the open source tools you find yourself using. -Steve On 23 Dec 2009, at 02:27, Kasim wrote: I am just thinking if anyone can list

Stream processing

2009-12-23 Thread jim
Here's a new piece I wrote about stream processing in Clojure. It's rushed and incomplete, just like the library. But I'm not going to have time to do much work on things after Christmas, so I wanted to get it out in case it might inspire others.

It's a little shorter if you unconditionally concat repeat. (defn append-val [val colls] (let [maxlen (apply max (map count colls))] (map #(concat % (repeat (- maxlen (count %)) val)) colls))) user (apply map + (append-val 0 [1] [2 3] [4 5 6])) (7 8 6) -- You received this message

If you are doing GP, another approach to avoid using eval would be using a tree of closures. http://xach.livejournal.com/131456.html is an example of the technique used in Common Lisp (should be similar enough). -- You received this message because you are subscribed to the Google Groups
