[resolved]slice text? <.<

[Apidcloud]

Hey there XD
Im in trouble...(again)
How can I 'slit' text when it reaches the border of the text box? XD

I've seen this:

text = self.contents.slice_text("string", 400)
    text.each_index {|i|
        self.contents.draw_text(270, 36 + i*32, 460, 32, text[i])}

class Bitmap
  def slice_text(text, width)
    words = text.split(' ')
    return words if words.size == 1
    result, current_text = [], words.shift
    words.each_index {|i|
        if self.text_size("#{current_text} #{words[i]}").width > width
          result.push(current_text)
          current_text = words[i]
        else
          current_text = "#{current_text} #{words[i]}"
        end
        result.push(current_text) if i >= words.size - 1}
    return result
  end
end

Ok, I dont get 'all the code' yet..so i need your help to understand it XD

That piece of code does something slightly different. It splits the lines depending on words. If a word doesn't fit anymore in the current line, it is put into the next one.

Well, it is the same point i think..But i dont understand it that well...

I don't get what this line does:

result, current_text = [], words.shift

--' I've never seen anything like that XD

And then, there is the problem with:
self.text_size("#{current_text} #{words}").width

text_size returns the rect of the self.contents.draw_text... but I don't know what's the meaning of that stuff inside ( )

see u

This here:

current_text = "#{current_text} #{words[i]}"

is basically the same as this here:

current_text = current_text + " " + words[i]

And text_size returns a Rect that has the dimensions of the area how much is needed to draw that text. When I use width, I know exactly how much the whole string needs. If it's bigger than the given width, I cut off the newest word and put it into the next line instead.

That doesnt make sense at all --'
current_text = current_text ? 

What about that line
result, current_text = [], words.shift ?

See you

No, not this:

current_text = current_text

but this:

current_text = current_text + " " + words[i]

Of course it makes sense. It adds a space to current_text at the end and words[i].

hmmmmmmm I think i get it now...
but where's current_text initialized?
it goes direct to the else of the branch then?

This piece must be a little confusing for you:

result, current_text = [], words.shift

It's the same as:

result = []
current_text = words.shift

current_text is initialized to the first word that was found in the string.
