Subject: String spliting and inclusion

Hi all,

I am having trouble working out some logic for my problem. I basically
have a long string (320 characters) and I want to split into smaller
strings no longer than 50 characters in length. At present I have the
following regex:

data = "big long string"

puts data.scan(/{50}/)

This nicely breaks up the string however there are a few problems with
it, including:

It only outputs 50 character chunks, therefore when it gets to the end
and only 20 characters remain it misses them off the output (it outputs
6 50 characters strings and ignores the remaining 20)

This regex also splits up words, which is something I don't want. I want
a script to count to 50 and when it gets there, go backwards to find
some white space and split it at that point, therefore not breaking up a
word. As a result a number of sub strings of various sizes will be
created all less than 50 chars.

I hope this makes sense, to summarise I want to break up a string into a
max of 50 characters without breaking up words.

Thanks in advance

Stuart
