Comment on Handling Ruby’s String.each_char Iterator by Travis B

If you click on the source in the docs, you get:

# File lib/jcode.rb, line 209
def each_char
if block_given?
scan(/./m) do |x|
yield x
end
else
scan(/./m)
end
end

so yeah, just do “string”.scan(/./m)

@Nick Great comment, I don't work with a whole lot of multi-byte character encodings. In this case, Jcode would be the way to go for Ruby 1.8. I haven't played much with Ruby 1.9 but I am excited to play with the better supported encodings that are baked right in.

Another “thanks” on the pile!

Will, unfortunately each_byte can cause problems with multi-byte character encodings.

Comment on Mergesort and Quicksort with Dynamic Languages by cazacugmihai

——-GROOVY QUICKSORT————–

def quickSort(List lst) {
if (lst.size() <= 1) return lst
def (less, greater) = [[], []]
def pivot = lst.remove(new Random().nextInt(lst.size()))
lst.each {
if (it < pivot) less << it
else greater << it
}
quickSort(less) + pivot + quickSort(greater)
}

Instead of random parameter you can use (list.size() / 2)

Thanks for info. It is sometimes quite difficult to convert some program from one language to another. Such comparisons come in very handy.

Thanks, great info nicely written up. Shame this common functionality is so obscure!

Thanks man! That’s what I was looking for.
“string”.each_byte { |f| puts f.chr }
