Posted the initial abstracts and participants for TUG'11 in Kerala, India. More, please!

The TUG books page has some new book reviews, member discounts, and other info. Thanks to Boris Veytsman for taking this on.

TUGboat 32:1, issue #100, arrived in my mailbox yesterday, and is now posted as usual. Cover came out nice, I was a bit worried.
Made TUGboat 31:1 fully available publicly, being a year since publication as usual.
TeX Live pretest started, most platforms have the new binaries already.
Last night's was the final build for tlnet of TL'10. Pretests coming soonly ...
I expect either tonight's or tomorrow night's build will be last for
TeX Live 2010.
Gotta freeze tlnet updates so we can start checking in new binaries and
start the TL'11 pretest.

Belatedly discovered that removing trailing whitespace with s/\s*$// instead of s/\s+$// was costing a full second of runtime every time the texlive.tlpdb file was read (about 50% of the read time). Furthermore, we apparently don't need to remove trailing whitespace at all (more savings). Unless I'm missing something obvious, this should be a nice fix for the 2011 release :).

Uploaded next TUGboat (issue #100) to the printer. Always such a nice feeling to ship another one. Now, back to TL testing & doc.

I sent these ideas for url.sty to Don Arseneau a few days ago. While awaiting his reply, though I'd post here too.

1. It seems like & should be a special character, since it's one of the url separators. If you think it's too late to add it by default, we could at least have an option like [amp] to turn it on. What I did for now was just:


\let\saveurlbreaks=\UrlBreaks
\def\UrlBreaks{\do\&\saveurlbreaks}

2. I often find myself needing to explicitly force a line break instead a url. I've used ! for this. Another option, like [bangnewline] or something? I can't think of a good way to make the special character configurable, or to do it on a per-url basis, either of which would probably be better. What I did for now:


\mathcode`\!="8000
\let\saveurlspecials=\UrlSpecials
\def\UrlSpecials{\do\!{\newline}\saveurlspecials}

3. Sometimes I find myself wanting to allow stretchy glue around / characters (only) to help with justification, etc. In practice it's proven too much to allow glue around any of the other usual characters. Unfortunately this now allows a line break between the slashes of http://, but again, nothing obvious came to mind for dealing with that :(.


\mathcode`\/="8000 % space around /'s.
\def\Urlspaceyslash{%
  \mskip\Urlslashmuskip
  \mathbin{\hbox{/}}% need text / to avoid recursion
  \mskip\Urlslashmuskip}
\let\saveurlspecials=\UrlSpecials
\def\UrlSpecials{\do\/{\Urlspaceyslash}\saveurlspecials}

4. Finally, the documentation is evidently stale. It refers to \Url@do, which I do not see defined. If you like I can work up some updates. (Now that we have url.tex, do we need to keep up the documentation in url.sty? I'd be inclined to remove it instead of maintaining it twice, personally ...)

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
