Example from the main page isn't working because of missing size method, all in 'god mode'. Code:

R.god_mode('')
"kampai".ljust(10, ' ') // => '  kampai  '
  .size() // 10
  .times(function(i) { console.log(i)} )

After some shallow debugging I suspect RWrapper to mess around with it.

BTW what's the point of these lines:

_str = R._str = (str) ->
  new RWrapper(str, _str)

It seems they will be executed each time I create a string and because of the outer scope it'll be nested one level deeper every time. Am i missing something?

Consider to allow god mode to prefix only non-overridden methods. This can be tricky as ES spec evolved, but still it gives you compatibility and comfort in the same time.

Exciting stuff. This library looks like a great aid for using a familiar standard library to learn an unfamiliar language and execution model.

Is an R.Hash expected to support object keys at this time? For me, an R.Hash behaves like a JavaScript Object:

require 'rubyjs'

a = {name: 'a'}
b = {name: 'b'}

h = R.Hash.new
h[a] = 'value of h[a]'
h[b] = 'value of h[b]'

console.log "a == b?", a is b # => a == b? false
console.log h[a] # => value of h[b]
console.log h[b] # => value of h[b]

Perhaps I was supposed to implement a hashcode function on a and b?

R([1, 5, 3, 5, 5]).shuffle()

=> Array {native: Array[5], constructor: function, all: function, any: function, collect_concat: function…}
native: Array[5]
0: 1
1: 5
2: 5
3: 5
4: 5
length: 5
proto: Array[0]
proto:

_a.shuffle([1,2,3,4,5])
=> [1, 5, 3, 5, 5]

thank you

Provide rubyjs as a npm module, so features can be used in nodejs on the server side

When using the 'god mode' with override set to true i've got a stack overflow. Code to reproduce (CS)

{ R } = require('rubyjs')

R.god_mode '', yes

test = "kampai".ljust(10, ' ')

Result:

.../node_modules/rubyjs/ruby.js:83
      val = this.valueOf();
                 ^
RangeError: Maximum call stack size exceeded

Running on Ubuntu 16:

> coffee -v
CoffeeScript version 1.11.1
> node -v
v6.7.0
> uname -r
4.4.0-47-generic

The lib version:

"rubyjs": "^0.7.2"

I haven't seen this error before. Running R("foo") after require 'rubyjs' causes it:

coffee> R("foo")

Bleaugh.

Some JS plugins already got gems for Rails

Like Underscore and Timeago

It's better than checking some repo constantly for update

What should be the name of the gem? rubyjs-rails?

_a.min [16, 14, 12, 11, 9, 7, 6, 4, 2, 0, 1, 3, 5, 6, 8, 10, 12, 13]
= > null
R([16, 14, 12, 11, 9, 7, 6, 4, 2, 0, 1, 3, 5, 6, 8, 10, 12, 13]).min()
=> null

am i missing something?

thank you

This is probably unfixable until Proxies are out.

a = [1,2,3]
R(a).each(function(n){
  console.log(n)
  a.splice(a.indexOf(n), 1)
})
// > 1
// > 3

The input array is not copied and modifications to the array produce unexpected results. Perhaps the README.md could illustrate this behaviour and how modifying an input array is a bad idea.

Perhaps something could be logged when the length of an input array changes between yields.

I solved this with a simple .reject.
