treemacs-follow-mode on remote(tramp) server

[ileixe]

Hi, I wonder treemacs-follow-mode is working (I'm not at least) on remote server. If not, any guidance to support it would be appreicated.

I'v never worked with remote files in Emacs, so I don't now how treemacs handles them. Let's first check if treemacs is able to even find your file. Open it and call treemacs-find-file.

If that doesn't work, try both of these code snippets. They must be evaluated inside the file you want followed.

(with-selected-window (treemacs-get-local-window)
  (treemacs-find-file (buffer-file-name (current-buffer))))

(with-selected-window (treemacs-get-local-window)
  (treemacs-find-file (treemacs-canonical-path (buffer-file-name (current-buffer)))))

treemacs-find-file seems to find right place. (It's not in project but I think it's unrelated in that it's same as local)

[Treemacs] /kubectl:ubuntu@yan-cpu-0:/home/ubuntu/kernel/furiosa-hal2/src/physical/commit/commit.rs does not fall under any project in the workspace.

I've been used treemacs in tramp well, and only thing that I've felt different from now is treemacs-follow-mode.

What does this mean exactly, the file is found anyway because it's also local?

Also what do you see when you call trace-function on treemacs-find-file-node?

I myself don't remember what I supposed to say 😇
