If there is one thing that is annoying when you us pdflatex in Emacs, it is the behavior of Adobe or another commercial product. If you haven’t closed the pdf-file, Emacs or better LaTeX will complain that the pdf-file is still open. I found some tricks in the internet, but I did not manage to implement them properly (you can for example use sumatrapdf, but I wanted to keep my original pdfreader on my computer).
Finally, I decided to use my macro/script program winautomation (www.winautomation.com).
I bought this program a few months ago after getting tired of the open source program Autohotkey (which is quite good, but you have to program a lot). Winautomation is just point and click. I wrote a lot of macros that make my life much simpler. For example, I have some scripts that start my subversion backup on my servers, some scripts that open the explorer in a certain directory, a script for logging in at the university, etc.
For the problem above, I did two things: I wrote a script that checks if the pdf-viewer is open, and closes it and integrated it in an Emacs macro.
Here is the script in winautomation:
In Emacs I recorded a macro with C-x ( and C-x ) in which I run a shell command:
Alt-x shell-command Enter
d:\inbox\closepdf.exe (this is the script I wrote with winautomation)
C-c C-c (starting latexing)
After some trial-and-error, I now have a Emacs-keyboard macro that exactly does what I want: it closes the pdfviewer program using the winautomation-script and compiles my tex file to pdf.
I changed my settings for latex to always produce a pdf-file by putting the following line in my .emacs
(setq TeX-PDF-mode t)
so now I don’t have to bother about the proper file-format for figures (no converting to ps, etc.).
The last thing I had to do was assign a key to my macro in Emacs. This is done by first naming the keyboard macro I recorded using “Alt-x name-last-kbd-macro” and after that save the macro in my .emacs file with Alt-x insert-kbd-macro and attach a key to it:
Here is the code snippet for the .emacs file
Of course, all this is also possible with autohothey or AutoIt,
