Re: [emacs-wiki-discuss] opening pdf documents

[Ray Fix]

This thread goes way back but I finally figured something out about it 
so here is my report.  ;-) When we last left our enthusiastic novice, 
he was having trouble with non-text links.  For example:

[[/some/path/file.txt][Text File]]    Good
[[/some/path/file.png][PNG]]        Non-optimal
[[/some/path/file.pdf][PDF]]          Non-optimal

All of these files would open in text mode.  Upgrading my version of 
Emacs fixed the PNG case.  Now it inlines the picture. Yay!  (Charles 
guess that my emacs was not compiled correctly was probably correct.)

However, I was still having problems with PDF files.  (Again it would 
open them as a text file....)

My solution here was to use trivial mode as described on:

http://www.emacswiki.org/cgi-bin/wiki/TrivialMode

I am using MacOS X 10.3.5 so I hacked at the lisp a little to make it 
work for me better.  (When it opened the file it injected the words 
"open process complete" into the original pdf buffer.)

(defun define-trivial-mode(mode-prefix file-regexp &optional command)
  (or command (setq command mode-prefix))
  (let ((mode-command (intern (concat mode-prefix "-mode"))))
    (fset mode-command
          `(lambda ()
             (interactive)
             (start-process ,mode-prefix (get-buffer-create 
"*open-trivial-mode*")
                            ,command (buffer-file-name))
             (kill-buffer (get-buffer buffer-file-name))))
    (add-to-list 'auto-mode-alist (cons file-regexp mode-command))))

(define-trivial-mode "open" "\\.ps$")
(define-trivial-mode "open" "\\.pdf$")
