pronounced 'eeya'

oia(do 
  (def xf 
    (compose 
      (drop 20)
      (map (fn [x] (mul x 3))) 
      (filter (fn [x] (eq 0 (mod x 2)))) 
      (take 10)))
  
  (prn (seq (range 500) xf)))

  //> [ 60, 66, 72, 78, 84, 90, 96, 102, 108, 114 ]

usage

npm install oia -g
oia script.js | node

why?

• js interop
• immutable + transducers + channels
• ui components
• tooling

kinda works

• working repl
• test suite
• user guide
• lisp-ish
• forked from ki
• js interop / macros (via sweet.js)
• immutable sequences, lists, maps, sets, cursors (via immutable & immstruct)
• lexical scoping
• loop /recur
• destructuring
• :keywords
• transducers (via transducers.js)
• exception handling
• chaining
• multimethods
• generators / channels (example)

in progress

• tooling: bin / source maps / browserify / repl
• macros

future

• react macros
• pattern matching
