Problems with Emacs vterm

Problems with Emacs vterm

[Christian Miller]

Hello,

I have two problems with vterm.

1: It does have directory-tracking according to it's manuals.  I also
looked at the package and the required scripts are present.  But this
feature does not work for me.

2: I don't know why but TRAMP is not working with vterm, too.  It
opens a new buffer that is killed instantly.  This also breaks the
prompt of newly created vterm buffers for me.

Those features work for Eshell though.

Both work on my Guix System.  The ‘2.’ works both for a Guix and non
Guix systems.

Do you use Bash as a shell for local and remote systems?  What is your
Guix version and is it a Guix System?

Interesting. (directory-tracking) It never did work for me since
several months.  I also created a VM to be sure that it is not my
Emacs config.  Does not work in the VM for me, too.

This is how I tested it.

Use the following file as preset:

;; Once installation is complete, you can learn and modify

(use-service-modules desktop networking ssh xorg spice)

  (users (cons* (user-account

                  (group "users")
                  (home-directory "/home/test")
                  (supplementary-groups '("wheel" "netdev" "audio" "video")))
                %base-user-accounts))

$(guix system vm <file>.scm) -m 4096 -smp 2

(in the VM)

1. Start Emacs
2. M-x vterm
3. cd Downloads
4. C-x C-f (find-file): It starts with "~/" instead of the expected
   "~/Downloads/"

Yes, I use Bash for local and remote.  I currently use GNU Guix System
on revision c1fda6cf61d4044d65c694cd309ca88c6b1ed5b7.
