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.

Do a search for CSV or comma separated values. Or just the word comma.
And, narrow the search to messages by me, Lucius. You will find that it has
it includes such a tool that is very similar to your split(). It uses an
object, (sequence or atom) as a split delimiter. It is not currently
available at my website. I will have to correct that oversight on my part.
