Re: pretty-print by default?

To do this from a simple command line, just do: java -cp clojure.main -e "(require 'clojure.pprint) (clojure.main/repl :print clojure.pprint/pprint)" modify to taste. I once figured how to do this in Slime, too, but when I look at my (quite dated) copy, it looks like pr-str is hard-coded. Tom

Re: about lazy-seq

(count coll) needs to realize the whole sequence all at once in order to see how big it is. Depending on how much of this you want to do "by hand", something like the following is how I would write it: (defn slice [low high coll] (lazy-seq (cond (pos? low) (slice (dec low) (dec high)

about lazy-seq

Hi, As a clojure beginner I'm practicing my understanding of the language but at some point the use of lazy-seq get blurry. Imagine that I want to write a lazy function to extract a slice of a collection something like this : (defn slice [coll low high] (drop (dec low) (take high coll))) .

I have the identical problem to Shoeb. Toohey's suggestion did not work for me. But I got it to work. What I found is that "lein deps" downloaded the wrong version of swank-clojure. Note that previous to this I had done "lein plugin install swank-clojure 1.3.1" That installed "swank-clojure-1.3.1.
