A Clojure-like Lisp on Rubinius.
Try to contain your excitement, please.
First of all, you're going to need Rubinius. If you're using RVM:
$ rvm install rbx $ rvm use rbx $ gem install apricot
Apricot provides an awesome read-eval-print-loop with line editing, history,
tab-completion, and some interesting commands like
!bytecode. To enter the
REPL just run
Once in the repl you can get help with
!help or use
(doc <name>) to see
the documentation of any function or macro. Play around, read
kernel/core.apr and try out our functions, and make some of your own.
Experiment. Tell us what you think!
apr> (+ 1 2 3) => 6 apr> (map (fn [x] (* x x)) (Range. 1 10)) => [1 4 9 16 25 36 49 64 81 100] apr> (defn square [x] (* x x)) => #<Proc:0x330@(eval):3 (lambda)> apr> (map square (Range. 1 10)) => [1 4 9 16 25 36 49 64 81 100] apr> (map (comp str square) (Range. 1 10)) => ["1" "4" "9" "16" "25" "36" "49" "64" "81" "100"] apr> (doc comp) ------------------------- comp ( [f] [f g] [f g h] [f1 f2 f3 & fs]) Take a set of functions and return a fn that is the composition of those fns. The returned fn takes a variable number of args, applies the rightmost of fns to the args, the next fn (right-to-left) to the result, etc. => nil
So you want to put your program in a file and not type it into the REPL? Sure:
$ cat hello.apr (println "Hello, world!") $ apricot hello.apr Hello, world!
If you want to hack on Apricot, first install Rubinius as explained above.
cd to the Apricot git repo, RVM should automatically switch to
Rubinius thanks to the
.ruby-version file. Now install and run Bundler:
$ gem install bundler $ bundle
You're all set. Run the tests with
rake and run the bleeding edge REPL with
ruby -Ilib bin/apricot. Similarily, use
irb -Ilib -rapricot for an IRB
session with Apricot loaded.
