split() function

Hello all .

Anybody that's programmed in perl or PHP knows that the split() function is
extremely useful.

When i first downloaded Euphoria, I was suprised that there was no split
function seeing as it's main datatype can be used to express strings. So one
day i set out to write my own split() function, after several bad attempts,
i came to a very obvious and efficient function.

here it is :

global function split(atom char,  sequence string)
  sequence ret
  integer c
  ret = {{}}
  c = 1
  for i = 1 to length(string) do
    if string[i] = char then
      ret = append(ret,{})
      c = length(ret)
    else
      ret[c] &= string[i]
    end if
  end for
  return ret
end function

so far you can only use atoms to use a delimiters to split strings by.

use the function like this:

sequence s,words

s = "hello!world"

words = split('!',s)

anybody who writes euphoria programs that require text parsing would find
this function extremely useful,if they haven't written it already.
