Re: [pygame] Good code for text wrapping?
Just posting to say that no, I haven't forgotten about this. I'd just forgotten how many things I have to work on. Anybody got a cloning device handy? Failing that, give me a prod if there isn't a basic working version up by Wednesday. It'll only take a couple hours, I just need to find a couple hours when I'm alert, not doing something else, and interested in coding. -FM
Re: [pygame] Good code for text wrapping?
cool. There's no rush :) I haven't gotten back into the text wrapping mood yet either. I saw your mock font, for testing. That's a good idea. cu, On Fri, Oct 10, 2008 at 6:13 PM, Charlie Nolan [EMAIL PROTECTED] wrote: Just posting to say that no, I haven't forgotten about this.

Re: [pygame] Good code for text wrapping?
I like Greg's suggestion, it sounds like the sanest way to handle this. I'll go ahead and rough out a skeleton system. René - Yeah, I'm thinking we'll just use a bare class, since it's got somewhat nicer syntax than a dict. (style.bold instead of style[bold]) As far as inheritance goes, the default should probably be to clobber everything, but it might be nice to allow bleed-through too. Useful, for instance, if you wanted to set the entire passage bold but it already had individual colors/italics/underline in place. -FM On 9/25/08, René Dudfield [EMAIL PROTECTED] wrote: hey, I like the idea of doing it as a separate module. let's work on it here... http://code.google.com/p/pygame/ branches/text/ I've added you to the project... (if anyone else wants to help with it, please send me your email off list). A simple style dict/class which goes along with each part of text would work fine I think. This method seems to work ok for html/css etc. We need to make sure that styles can be applied inside of styles. I guess a simple inheritance would work there? Either: - child styles inherit from the top, over riding what they declare? - child styles are completely new, inheriting nothing? I think the simplest implementation would to make the style be applied as is... with nothing inherited from the parent.

Based on mouse click, which letter and word does it collide with? - each part of text having a separate font/attributes. So you can then do words with bold, italics etc. - letter spacing - line spacing - word spacing - flowing around areas... - eg( place an image, and the text flows around it) - example here: http://www.csstextwrap.com/example_for_demo.php - indenting - padding around text. - text color - text render method.

René Dudfield [EMAIL PROTECTED] writes: Shall we start by making an ultimate list of features, or use cases... snip Anything else? Eventually, you'll want: - text flow other than left-right (right-left, mixed, top-down) - support for non-letter fonts (e.g. button glyphs for help text) -- although I suppose you could handle it by something you described, flowing text around images, if the images could be floated as well - support for non-breaking spaces and hyphens - proper handling of line-breaking in different languages (e.g., French inserts a space or two between the last letter of a sentence and a final exclamation point, don't want to break there, some languages consider certain combinations of letters to really be only one, can't break in between them, etc.) - proper support for full Unicode fonts But this is a bit pie-in-the-sky, it can wait until the basics are in, I just have text processing on the brain a bit lately :) =wl -- The whole fist fight is over who gets locked up and thrown rudely to the ground and tied into little greasy knots. -- Chas Clements

Re: [pygame] Good code for text wrapping?
hi, The cookbook entry has been updated with a multiline function, that seems to work ok. http://www.pygame.org/wiki/TextWrapping I guess for right justify, the lines could be blit from the right of the screen minus text width. To center it, you would blit at the (screen_width - text_width) / 2. cheers, On Tue, Sep 16, 2008 at 10:09 PM, Michael [EMAIL PROTECTED] wrote: On Tuesday 16 September 2008 03:11:45 René Dudfield wrote: The cookbook has this entry, but it doesn't work with new lines. http://www.pygame.org/wiki/TextWrapping Anyone have any code like this that supports new lines?
