A new release of the HTML Parser is available. The new version 1.4 contains minor adjustments to spec compliance and fixes for notable Java-specific problems (of the crash and infinite loop sort). Also, the parser is again available from the Maven Central Repository (groupId: nu.validator.htmlparser, artifactId: htmlparser, version: 1.4).

Upgrading to the newest version is recommended for all users of all previous versions.

Patent Policy

Tuesday, April 24th, 2012

The WHATWG now has a patent policy, the WHATCG. We will keep using the same mailing list, the same IRC channel, the same web sites, but now sometimes we will publish through the WHATCG as well for patent policy purposes per the W3C Community Final Specification Agreement.

If you could previously not join the WHATWG because no patent policy was in place, now is the time to reconsider. If you are unsure how this applies to you, then it most likely does not.

HTML Editing APIs specification ready for implementer feedback

Wednesday, July 27th, 2011

(This is a cross-post from the mailing list, reformatted as HTML.)

Since February, I've been working on writing a detailed specification for browser editing, primarily the document.execCommand() and document.queryCommand*() methods. These were created by Microsoft in the 1990s and were subsequently adopted in some form by all other browsers, and today browsers have to implement them to be compatible with web content, but no detailed specification ever existed. Interoperability is practically nonexistent as a result, which has driven all major content editing frameworks away from using execCommand(). (For instance, I began typing this in WordPress' WYSIWYG editor, which uses TinyMCE – a major editor that avoids execCommand() entirely.) Hopefully we can start to fix that and make these APIs a part of the web platform that just works.

The current version of the specification is about fifty pages printed, and supersedes the Editing APIs section of HTML (which is more like two pages). In the style of modern web specs, it is phrased in terms of algorithms that attempt to cover all corner cases unambiguously and leave no behavior undefined, and it tries to match the behavior of existing browsers to the greatest extent possible. At this point, it's stable and complete enough that I believe it's ready for serious review by implementers, and I would like as much detailed feedback as possible.

There is a basically complete JavaScript implementation, which is used to produce expected results for a largely undocumented and entirely ad hoc test suite. I used the tests as an aid to writing the spec, and they probably aren't well suited to aid implementers in implementing it. I will probably get around to porting them to something like testharness.js at some point. I haven't tried testing my implementation on real-world sites, only on artificial input, so I don't know at this point how implementable it really is, but the JS implementation means that it at least has large parts that make sense.

Anyone reviewing the spec should be advised that I put extensive rationale in HTML comments. If you want to know why the spec says what it does, check the HTML source. I plan to change this to use <details> or such in the near future. There are lots of minor known issues still left, but none that I thought was important enough that it needs to delay review. Feedback can be sent to the whatwg list, CCing me, with [editing] in the subject. (I'm also fine receiving feedback on public-html or public-webapps, but I don't know if the chairs would be okay with that, since it's off-topic.) I should be available to respond to all feedback promptly at least through the end of August. After that, I can't make specific guarantees about my availability, but I do plan to continue maintaining the spec in the long term.

WHATWG Weekly: End of HTML5 Last Call

Monday, July 25th, 2011

Next week Wednesday, August 3, the W3C HTML5 Last Call review period ends. Consider taking another look and giving some feedback!

Here is a quick rundown of what happened last week:

Since the summer causes a slowdown of everything standards, the next WHATWG Weekly is in two weeks.

The WHATWG Forums

Monday, March 21st, 2011

First thing's first. Hi my name is Liam Hockley, I am a recent addition to the admin team on the WHATWG forums and I have been working on improving the site over the past couple of weeks. (

The first thing I did, was update the forum software from the severely outdated phpBB2, to the fresh new phpBB3. This process went fairly smoothly. Next I created a new forum section to facilitate the discussion of forums/website ideas and feedback. On top of this, the other admins and myself  have been working to make sure spam is not and will not be an issue moving forward.

The next step and what we are currently working on, is to try and get the forums more active. I would like to encourage you to use the forums and tell all of your friends. This could serve as a great base for compelling discussion and debate on the HTML spec.

In the future, I plan to try and implement integration of the twitter RSS feed and potentially an RSS feed of the WHATWG mailing list. There is also an effort in place on the part of phpBB, to modernize their markup to follow the latest HTML spec in upcoming releases. We will most certainly be taking advantage of that once it becomes possible.

Anyways, thank you for reading. If you get a chance, check out the forums and drop us a line.

-Liam "Xdega" Hockley
