Great, thanks!  Any advice on the right way to cite the Homebrew package 
on the Ur/Web home page, similarly to how other packages are cited now?

Hi,

The pull request for homebrew-core was merged, so there's no more need 
to use the experimental tap.


I updated to the latest release just before they merged.

Re: [Ur] New release

[austin seipp]

I've updated a 'brew' formula for homebrew users. Any OS X people who
want it through brew can do:

$ brew install 
https://raw.github.com/thoughtpolice/homebrew/urweb/Library/Formula/urweb.rb

for the latest release. I removed the binary version because otherwise
it wouldn't be accepted into their repository (only they are allowed
to make binaries.) It should hopefully be in mainline soon, so you
won't have to use an out-of-band URL.

Just for your Info!
On the page (http://www.impredicative.com/ur/more/)
I got the following error message by clicking on Grid1:

Fail: ReferenceError: _16 is not defined

Which browser are you using?
Firefox 3.5.3 on Mac OS X (10.5.8, Intel)!


OK, the new Ur/Web release works for me in the latest Firefox.  I'm 
pretty confident that it's a Firefox bug that caused the trouble, but 
I've changed the compiler so that that sort of bug shouldn't cause 
trouble in the future.



I didn't get this error in Safari 4.0.3.
However, the borders around the grid elemets
are missing!


I have no idea how to deal with this, and it's infeasible for me to test 
anything on a Mac, so I'll ignore this for now.



There are also two messages in error console:

/ur/more/More/Grid1/main:12  XML self-closing tag syntax used on th. 
The tag will not be closed.
/ur/more/More/Grid1/main:89  XML self-closing tag syntax used on td. 
The tag will not be closed.


Thanks.  I've changed the compiler to avoid self-closing tags that 
weren't traditionally self-closing in HTML.



IE 8.0 on WinXP works. There is also an error message


I'm going to ignore IE for now, since I want to prioritize developing 
case studies that demonstrate why metaprogramming is nifty in Ur.
