Re: Loading local .emacs from remote machine

[gebser]

Kai,

Thanks for the feedback.

I looked around and it seems I'd have to upgrade to RH 8.0 to be able to use
texinfo 4.2; it would require upgrading some other more central system files.
I'd like to have the info files, but today isn't the day for me to do a full
upgrade.  But maybe we can still get tramp working.  (See below.)

This would help out those of us who don't upgrade with each new version 
that comes out.  I know a lot of people still on rh 7.2.

I was following the documentation.  What would be the way to load a 
*.texi file?

Again, the command I used was directly from the docs.

People say that....  Well, they don't give me a "Wow", but yeah.  :)

This is where I was reading the aforementioned docs.

= Yes, I also guess that the shell prompt wasn't recognized.  Lessee
= now, what is the default value of tramp-shell-prompt-pattern?  Hm.
= It should have matched this prompt.
=

I don't know enough about this even to be confused....  8\


= 
= Could you put (setq tramp-verbose 10) and (setq tramp-debug-buffer t)

= Also, it would be good to do M-x toggle-debug-on-quit RET before

= 
= Oh, and removing tramp.elc before starting Emacs will give a prettier

Did all this.  Then tried to open a file on the same machine as before.

A string in elisp must be some really strange thing.

(add-to-list 'tramp-shell-prompt-pattern "abc")

also gives the same error.  It seems that everything and anything I put into
the third arg is a listp.  It's a shame elisp is so obtuse.  I'd like to learn
it so's to do some helpful work on emacs.  Several times I've tried to do
simple things in elisp, following books and tutorials, but never had any
progress with it.  Maybe I need to be dyslexic.  :)
