Polygonal text-wrapping, the output element and “wicked fast” page loading
Published on in Google Chrome, Last Week, Standards, tech, WebKit. Version: Chrome 9
Although, statistically seen, it has been quite a regular week with 1,096 commits, 494 for WebKit and 602 for Chromium, there have been some very nice changes and announcements over the past seven days.
As for ongoing work, Dave Hyatt added support for selections on vertical text, and made sure that repaint invalidation now works with vertical lines as well. Dan Bernstein committed basic support for multiple writing modes in tables, including support for collapsing borders.
Meanwhile, Chris Rogers has been busy landing parts of the Audio API in WebKit. The RealtimeAnalyser (and its Node) landed about a week ago, just like the ConvolverNode and the AudioBufferSourceNode. A class to pass on the active buffers to the onaudioprocess event, named the AudioProcessingEvents Interface, has been committed as well. With more patches in the queue, progress on the API steadily continues.
Several announcements were done during one of the keynotes at Adobe’s MAX conference last month, some of which illustrated Adobe’s interest in HTML5. Mark Anders introduced EDGE, giving web developers an interface similar to Adobe Flash for creating HTML-based animations on their websites. Furthermore, it was also announced that Adobe will be contributing an animation framework to jQuery, as well as proposing and contributing changes to WebKit.
Adobe is working together with Google to accelerate the process of landing the changes in WebKit, and thus making them available in a browser release. While the CSS property’s syntax is expected to evolve following community feedback, Adobe certainly intends to propose the feature to the CSS Working Group.
In terms of standards compliance, getComputedStyle received an update allowing you to retrieve all backgrounds instead of just the first one. The window.name property will now return an empty string for unnamed windows and frames and, in preparation of landing the actual interactive validation UI, a framework for showing the messages has been added as well.
Kenichi Ishibashi added support for the HTML5 <output> element, which is intended to represent the result of a calculation of two or more other form fields. After a way too long period of time, Erik Arvidsson landed an adjusted version of my patch to support the unprefixed box-sizing CSS property. Finally, since the IETF now seems to consider prefixed HTTP headers harmful, the “X-Purpose” header has been renamed to “Purpose”.
More updates which occurred last week:
- The integrated PDF viewer has landed in Chrome’s Beta channel.
- A minor update was done to the EULA of Chrome OS, clarifying the concept and implications of themes.
- All the poor folks with e-mail addresses ending with @google.com have hard-coded screen locking.
- Instant has been added to the tabbed options, as well as a confirmation dialog.
- The Native Client may now be enabled through about:flags, allowing you to play Conway’s Game of Life.
- Lots of polishing has been done on Web Inspector again.
- Work has started on predictively loading and rendering pages for “wicked fast” page loads.
- The error page template in Chrome has been updated to be a little prettier. I’m not sure I agree.
- Performance of SVG’s FELightning filter has been improved by about 40%.
- The File System API now works in extensions for Chrome as well.
- The HTML5 <video> element has been enabled by default for WebKit’s EFL port.
- The filename parameter of the Content-Disposition header can now use the extended syntax.
- A confirm-to-quit dialog has been added for Mac installations, to be enabled via about:flags.
- Spatial navigation support will now be available for <input type=text> and <textarea>.
- Parsing of the text-combine CSS property has been added, not for the intended effect yet.
- Quite some fine-tuning has been done for Chromium OS.
Many thanks to Paul Gubbay and Alexandru Costin from Adobe for answering my questions. Also, this page contains a clear lead about what’s (hopefully!) to expect for next week 😉
