[TxMt] Announcing LaTeX Watch 2.0, with PDF support

[Robin Houston]

This new version uses PDFTeX by default, and will try to use TeXShop as the
previewer.
(Note that TeXShop is part of MacTeX 2007.)

The bundle is available (for the moment) here:

   http://www.puffinry.demon.co.uk/LaTeX%20Watch%202.0.dmg

This version should be almost ready to be incorporated into the LaTeX
bundle, so please let
me know about any problems.

The default behaviour can be changed by setting shell variables, as follows:

1. If TM_LATEX_VIEWER=TeXniscope, it will use TeXniscope instead of TeXShop
    (If you should happen to want LaTeX Watch to use a different previewer
from 'Compile and View',
    you can set TM_LATEX_WATCH_VIEWER=TeXShop to override the
TM_LATEX_VIEWER setting.)

2. If TM_LATEX_WATCH_MODE=PS, then it will compile via DVI, and use GV to
preview.

3. If TM_LATEX_WATCH_DEBUG=console, additional status messages will be
printed to the console;
    if TM_LATEX_WATCH_DEBUG=dialog, these status messages will pop up in
dialog boxes.


Incidentally, there is a utility in Support/bin/check_open that may be more
generally useful.
It uses the Carbon API to check whether a particular document is open in a
particular application.
(This is used to stop watching the document when you close its preview
window.) Of course
the same thing could be done with AppleScript, but that is too slow.
(Another alternative
would be to use the Perl-Carbon bindings that are included in 10.4, but that
would not work on
earlier OS versions.)

Since it's a bit of a pain to install GV, and since several
widely-distributed versions have
irritating bugs, I wondered about including a GV binary in the package. As
an experiment,
I built gv-3.5.8 as a universal binary with libXaw3d statically linked in,
and it comes to
about 3MB. Does anyone have an opinion on this?
