(It's not clear to me how your answer matches the OP's request...?)
The partition function in https://github.com/JuliaLang/Iterators.jl will do
this:
julia> using Iterators
julia> list = [1,2,3,4,5]
5-element Array{Int64,1}:
1
2
3
4
5
julia> for p in partition(list, 3, 1)
println(p)
end
(1,2,3)
(2,3,4)
(3,4,5)
Normally, "collect" will collect the elements of an iterable into an array.
In this case, though, there is a bug in Iterators.jl which causes problems
with this (the length of a partition is not defined properly.) I'll fix
this momentarily.
Cheers,
Kevin
