How to convert a string of arbitrary size to an array

ruby-talk
1

Team,

I am trying to convert a string of arbitrary size to an array of single
characters, bu I having a hard time.
A google search "Ruby" "string to array" returned thousands of hits. I
checked couple dozens but none satisfy what I want.

Say I get a user-supplied string (alphanumeric & special chars) of arbitrary
length.
How can I convert that string to an array of single chars?

Thank you

Check out String#split:

  "abcdefg".split( // )
  => ["a", "b", "c", "d", "e", "f", "g"]

In Ruby1.9 I am quite fond of this
514/16 > ruby19 -ve 'p "Hello World!".each_char.to_a'
ruby 1.9.1p0 (2009-01-30 revision 21907) [i686-linux]
["H", "e", "l", "l", "o", " ", "W", "o", "r", "l", "d", "!"]

Aha!
I tried:
"abcdefg".split( / / ) # Space between //
"abcdefg".scan(//)
and other...

Thank you very much for your quick reply.
