Thanks julian for your help almost at the end, little help more.
i used your regular expression
line_length = 40
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 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."
words = words.gsub(/(.{1,#{line_length}})(\s+|\Z)/, "<=\\1\n")
words = words.sub('<=', '')
abort words
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 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.
