[orion-dev] HTML content assist

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

I just released basic HTML content assist
in master. It relies on some fixes/enhancements to the content assist infrastructure
that is also in master, so you will need all the latest and greatest client
code to run it. Some notes:

 - It currently just auto-completes
on HTML element names. It doesn't fill in attributes except for some of
the most common cases (image, anchor)
 - Only the elements in the HTML
5 spec are included
 - For elements that typically
start a multi-line block, it will insert a new line and appropriate indentation
 - For elements that have a closing
tag, the completion will position the cursor between the open/close elements.
For empty elements like <br>, <hr>, etc, it positions the cursor
at the end
 - If you hit Ctrl+Space in a completely
empty HTML file it will auto-complete a basic well-formed HTML5 document
(good for demos!)

I'll probably keep hacking on it next
week, but in the meantime feel free to try it out and report bugs/enhancements
against Orion > Client in bugzilla.

As an aside, I think this was good validation
of how easy to use the Orion language extension model is. I just had to
write one 130 line script that generated all the proposals, and the orion
infrastructure did all the rest of the work. Most of our content assist
before now was just flat lists of keywords, but writing a more context
aware proposal engine with indentation, cursor positioning, etc, was not
a big step up. For anyone curious, here is the complete source:
