Turn OFF default TRAMP in Emacs 22.x, need VMS access

Turn OFF default TRAMP in Emacs 22.x, need VMS access

[nelson.ingersoll]

I am currently using Emacs v21.3 on platforms I am working on.  This
includes Windows 2K/XP, SunOS, Tru64, and Linux (flavors).   Would use
Emacs on OpenVMS if I could find a functioning binary for AXP.  Heck,
I'd use ANY version of Emacs on VMS if I could find a functioning
binary.  I've had no luck compiling it.

I have been playing around with newer releases of Emacs, 22.0.50
recently.  In all cases they have installed TRAMP in lieu of ANGE-FTP.
Alas, IMHO, TRAMP is much too slow and intense.  ANGE-FTP works, for me
at least, much better.  By an order of magnitude.   Salt in the ound,
TRAMP does not work in the least at all no way with VMS.   I work in a
VMS shop.  That REALLY kills TRAMP from my point of view.

So I want to use ANGE-FTP with Emacs 22.x.  Alas, setting the tramp
default method, ala (setq tramp-default-method "ftp"), still leaves
TRAMP in the path being difficult.   I want to get rid of it.
Completely.

How can I completely remove TRAMP from a release?  I can install
ANGE-FTP via my site-lisp directory and my .emacs file.  I commented
out the TRAMP section in ../lisp/loaddefs.el; however, that didn't
work.  Did I miss something or is there somewhere else to go as well?

Thank you for your help.

Add the following to your ~/.emacs:

(setq file-name-handler-alist
      (delq (rassq 'tramp-file-name-handler
		   file-name-handler-alist)
	    file-name-handler-alist))

This will kill tramp dead, but it won't reinstate ange-ftp, so you
have to do that.  Search for file-name-handler-alist in ange-ftp.el, and
you'll find some commented out code that shows how that is done.

Huh?  Emacs-22 comes with both ange-ftp and Tramp, both active by default.

What does "leaves TRAMP in the path being difficult" mean?
The setq you show should allow you to use ange-ftp just as before.  If it
doesn't, it's a bug which you should report.  It does go "through" Tramp,
indeed, but there should be no visible slowdown or change of behavior.

Other than out of irritation, why would you want to do that?
