Hi all,

Help needed urgently

Example: this could be the string.

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 learning and skill building with a sense of challenge, fun, and self esteem.

Output 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 => ......... ......... => a sense of challenge, fun, and self esteem.

Is the point of your post to display the text at fixed line widths?

Hi all,

Maybe it's just me, but I think that in your hurry you've neglected to describe what it is you want to do. Replace carriage returns with => \n<= ?

Try this: words = "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 commitment to parents, teachers, and kids, is to connect earning and skill building with a sense of challenge, fun, and self esteem."

line_length = 10

word_arry = words.split(" ")

text = (0..(words.length / line_length)).inject() {|v,num| start = num * line_length; v << %Q{<= #{words[(start)...(start + line_length)].join(" ")} =>}}

text.join("\n")

Shame on me...

I am quite a beginner; it is not clean clode but works

number_of_words = 10 sentence = sentence.split(/\n/m).join(" ") sentence.gsub!(" "," ") r = /.*?[.!?](?:\s|$)/ sentences = sentence.scan(r) sentences.map! {|e| e.split} v = sentences.each do |e|   while !e.empty?     vv =     number_of_words.times {vv << (e.shift.to_s + " ")}     v << vv   end end

v.each {|e| e.delete_if {|x| x == " "}}

v.map! {|e| e.join}

v.each {|e| p e}
