[OS X TeX] Emacs <-> TexShop

[Roussanka Loukanova]

This problem has been lately discussed under the subject "preview in 
TexShop was: Re: [OS X TeX] FYI: Smultron", but some people,
incl. myself have been mentioning it now and then.

It seems to me that it deserves a new tread and am slightly re-formulating 
it here.

I use Seiji Zenitani's Carbon Emacs with its latest default commands for 
LaTeX and View, which for a given <file>.tex typeset and view by the 
sequences:

1. latex -> View (open <file>.dvi)

The <file>.pdf is viewed in TeXShop.

2. pdflatex -> View (open <file>.pdf)

The <file>.pdf is viewed in Preview.

I consider these two options very good, except the following problem with 
TeXShop:

1. If TexShop had been left opened (behind emacs' window) while typing 
and typesetting in emacs, then via the command View, TexShop 
just pops-up to the front by displaying the older, instead of the updated 
<file>.pdf (on the page it was).

2. If TexShop had been closed (e.g., by Cmd-W or Cmd-Q):

a) If one typesets in emacs by using latex, then the command View opens 
TeXShop, which displays the updated pdf on p.1, instead on the last page 
viewed.

b) TeXshop always creates a *new pdf version*, when re-opened via 
Emacs' View command, after it had been closed (with or without typesetting 
in Emacs).

When <file>.tex and  <file>.dvi have the same time stamps
(e.g., when there is no update of <file>.tex, typesetting has been 
previously done and <file>.dvi is not removed), Emacs, with the 
key combination {Ctrl-c Ctrl-c}, automatically detects that and does not 
run the command latex, but invokes the default View command in the emacs' 
mini-buffer. But TeXShop creates new <file>.pdf: this means that the 
default opening of TeXShop runs dvi -> pdf or ex -> pdf.

These problems persist with the default AUCTeX commands; and with added and 
removed my own AUCTeX external commands.

I have in TeXShop Preferences

Document -> Source Window Position -> Remember last position on close 
(checked)
Document -> On Startup -> Configure for External Editor (checked)

Preview -> External Editor -> Automatic Preview Update (checked)

Here are my time stamps from a test after issuing {Ctrl-c Ctrl-c}, which 
invokes View in the Emacs' mini-buffer and closing TeXShop with Cmd-W.
