Subject: Loooong wordwrap

Hi all,

I'm certainly finding this a fun challenge but wanted to know if anyonw
can help

I'm trying to wrap long words that have no spaces, but only the
application is a game and I need to wrap a word based on its true pixel
font width and place this into an array of lines, only that I pass to
method the width in pixels that I need to wrap against.

for a game I;m trying to build (Gosu lib)

font.text_width is the true pixel length of the string
width is in pixels
text is a string

i.e.

def wordwrap(text,width,font)
    words = text.split(' ')
    lines = [words.shift]
    words.each do |word|
      if font.text_width("#{lines[-1]} #{word}") < width
        lines[-1] << ' ' << word
      else

        lines.push(word)
      end
    end


####I have loooooooooong word that needs wrapping
    if (text.index(' ').nil? and font.text_width(text) > width)


            ## I need to chop the string into parts so I have an array
of lines all measuring the "width" pixel width


    end

end


Could somebody help, I really have tried many ways and coming from PHP
I'm not too sure of how to do this in Ruby

Thanks!!
Art
