- # [02:26] <Hixie> is vertical text defined anywhere in any kind of stable state in css?

- # [06:18] * fantasai_ is now known as fantasai
- # [06:18] <fantasai> hixie: depends
- # [06:19] <fantasai> hixie: is the string going to wrap?
- # [06:19] <fantasai> hixie: wrapping adds another dimension to the problem
- # [06:19] <fantasai> hixie: there are several considerations for drawing text
- # [06:20] <fantasai> hixie: the line-stacking direction (block progression), which is top-to-bottom for most texts, and can be left-to-right or right-to-left in vertical texts
- # [06:20] <fantasai> hixie: that only affects multiline text
- # [06:20] <fantasai> hixie: another parameter is the bidi context direction
- # [06:21] <fantasai> hixie: rtl vs ltr, essentially
- # [06:21] <fantasai> hixie: then you have the text orientation
- # [06:21] <fantasai> hixie: which is.. complicated
- # [06:22] <fantasai> hixie: the most common cases are rotate-right and force-upright -- i.e. rotate non-vertical scripts clockwise 90deg, or keep individual glyphs upright
- # [06:23] <fantasai> hixie: the latter option has interesting implications for connecting scripts like Arabic
- # [06:23] <fantasai> hixie: vertical text isn't defined in CSS in any kind of stable state atm
- # [06:24] <fantasai> hixie: Paul, Steve, and I have a proposal that will cover most cases, but it is not properly written-up
- # [06:27] <fantasai> hixie: (some vertical text renderings are simply graphical rotations of the horizontal layout, I assume you've got that covered already)
- # [06:38] <fantasai> let me know if you need more details, diagrams, etc. one thing to be particularly careful about: don't copy SVG/XSL's glyph-orientation property, all three of us agree it's bad
- # [10:52] <Hixie> no wrapping
- # [10:52] <Hixie> and only the most common vertical orientation stuff
- # [10:52] <Hixie> nothing fancy in either horizontal or vertical modes
- # [10:53] <Hixie> let me know what the timeline on the vertical stuff in css is, we'll probably keep the html5 canvas vertical stuff commented out until we have a css spec to point to

- # [18:09] <fantasai> Hixie: I don't expect I'll have much time for it this year, I'll be focusing on Backgrounds and Borders, Generated Content, and Paged Media
- # [18:10] <fantasai> Hixie: for horizontal text, you do have a way to set the bidi context direction, right?
- # [18:11] <fantasai> Hixie: Text orders differently depending on what the overall "paragraph" direction is
- # [18:13] <fantasai> Hixie: Timeline for vertical text is probably WD sometime next year.
- # [18:59] <Hixie> yeah i'm going to rely on the canvas element's intrinsic direction
