#1835 — Using includes in Emacs

I am happily trying ‘some’ things with postscript again. It was a
little bit getting used to it after a while, but I am getting used to
it again.

The code I am writing is almost 1400 lines. That is a bit long. In
principal it are different modules. I am using Emacs and with
    C-c C-c

I get a view in Emacs. Is there a way to split the source in several
files and include them? I know about ‘run’, but that only works
without ‘-dSafer’. I could also use ‘gs’ with ‘-f filename’, but that
would be an external command.

At the moment I am using the following:
    (progn
      (shell-command (concat "cd " postscript-dir "; "
                             "gs -sDEVICE=pdfwrite"
                             "   -dNOPAUSE"
                             "   -dBATCH"
                             "   -dSAFER"
                             "   -dQUIET"
                             "   -sOUTPUTFILE=" output-file
                             "   -f meander.eps"
                             " " input-file))
      (find-file (concat postscript-dir output-file)))

It works, but it is not really perfect.

I have a small improvement:
    (progn
      (shell-command (concat "cd " postscript-dir "; "
                             "gs -sDEVICE=pdfwrite"
                             "   -dNOPAUSE"
                             "   -dSAFER"
                             "   -sOUTPUTFILE=" output-file
                             "   -f meander.eps"
                             " " input-file))
      (when (get-buffer output-file)
        (kill-buffer output-file))
      (find-file (concat postscript-dir output-file))
      )

It looks like -dBATCH was doing nothing. Also -dQUIT suppressed things
that I think are useful.

Also a ‘problem’ was the message you get when you did not close the
buffer with the PDF. So I build in that the buffer is closed when it
is open, before opening it.
