Hi.
I think what you want to do is word-wrapping across lines depending on
line length.
Here's a pretty nice algorithm using a regular expression:
class String
def word_wrap(line_length=80)
self.gsub(/(.{1,#{line_length}})(\s+|\Z)/, "\\1\n")
end
end
What this does is put the word_wrap method onto the string class.
So, you can do this:
string_to_wrap = "Kid games need to be both fun and educational. Aimed
at ages pre-K through middle school, safe environment to discover
their abilities and learn new skills with interactive and fun computer
games. Our games build skills in math, logic, memory, vocabulary,
alphabet, spelling, geography, computer skills, color identification,
shape identification and other various problem solving. Our commitment
to parents, teachers, and kids, is to connect earning and skill
building with a sense of challenge, fun, and self esteem."
puts string_to_wrap.wrap
If you want to change the number of characters that it will wrap at
(ie line length), which defaults to 80... then specify it as an
argument:
puts string_to_wrap.wrap(10)
Good luck, and remember that when posting questions to this list, it's
really good to carefully prepare your question.
Julian.
