[texworks] SCRIPTING: get current poppler page number

[Paul A Norman]

Hi,

APPLE MAC

  "When opening a PDF document with an Apple Event on a Macintosh
operating system,
  you can optionally pass the PDF Open parameters."

What does this mean to a Mac user please? - i.e. what is an "Apple Event"

I tried to search for this  but all I got so far was the kind of Steve
Jobs - Apple Event that Donald Knuth was having fun about in his iTex
{ding-a-ling} talk at TUG this year. :)

WINDOWS

Mixing things up I have found that the following kinds of things can
be done on the command line in  Win32 (and so TwApi.system() ), and if
acrobat reader 32 is being used, should work on Win64 as well, but I
can not check.  As outlined Apple Events are able to reproduce the
following as well according to:
http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/pdf_creation_apis_and_specs/PDFOpenParameters.pdf

This process is very fast (much faster than pdfopen on Xp under
MiKTex). I need to check for more switches like /A as otherwise we
need to close and rerun to get a different page number.
 - but it is fast.  The utility start is required as modern acrobat
reader does not appear to be on the path, and it can look up acrord32.

     start acrord32 /A "page=17" "D:\LaTeXPortable\LatexUtils\General
Files\dahdah.pdf"

     start acrord32 /A "page=41&toolbar=0&pagemode=thumbs"
"D:\LaTeXPortable\LatexUtils\General
Files\dahdah.pdf"

     start acrord32 /A "page=41&toolbar=0&pagemode=bookmarks&zoom=71"
"D:\LaTeXPortable\LatexUti
ls\General Files\blahblah.pdf"

LINUX

Is there a general Linux equivalent bash script to windows acrod32 for
starting an installed acrobat reader  please? Or is this going to be
distro by distro? I think on a number of distros  Evince is going to
try and step in otherwise, and it does not appear to handle the extra
pdf features that this is all about.

Or could I hope to rely on "pdfopen" to be present on genreal Linux
distors of TexLive? If so can I just call it directly and pass its
parametrers to it?

PREFERENCES

Another option

Tw tries to autodetect acrobat reader and/or User sets up a
prepferences option saying where their installed (and how to call)
acroread is, and TwScript be able to read it.
