StackOverflowError

[Gal Dolber]

Hi,

I've been playing with loop, loving it so far!

I'm getting StackOverflowError on this code:

subseqs(a) ->
  func.@call(a) + func.@call(a.reverse())
  where
    func: @(a) -> {a.subList(a.indexOf(i), a.size()) for i in a}

print(subseqs([-10,20,-34,10,22,-5]))

What am I doing wrong?

also, if I use a[a.indexOf(i)..] I get an error, array slicing doesn't work in most of the situations I tried

Thanks

Hi,

Thanks for the kind words! You're creating a closure on entry into the function every time, try this instead:

>> subseqs(a) ->

|      func(a) + func(a.reverse())

|      where

|        func(a) ->

|          a.subList(a.indexOf(i), a.size()) for i in a

|    

ok

>> subseqs([-10,20,-34,10,22,-5])

[[-10, 20, -34, 10, 22, -5], [20, -34, 10, 22, -5], [-34, 10, 22, -5], [10, 22, -5], [22, -5], [-5], [-5, 22, 10, -34, 20, -10], [22, 10, -34, 20, -10], [10, -34, 20, -10], [-34, 20, -10], [20, -10], [-10]]

As for the list slice, let me take a closer look--there is definitely some bug going on. Thanks for reporting it!

Oh, I see! thanks!!

OK have fixed the bug with list slice expressions. Now works as expected:

>> a:[1,2,3]

[1, 2, 3]

>> a[a.indexOf(2)..]

[2, 3]

Please update your distro.
