An emacs newbie here, i'm using doom emacs and i tried to use treemacs for navigation purposes however once i opened a project and toggle treemacs it shows the whole tree of files starting from $HOME, i saw somewhere that
treemacs-display-current-project-exclusively will do the trick but it actually doesn't , is this the expected behavior or am doing something wrong ?

  • How is the project defined - is it a git ptoject or by project.el or something else?

I've not checked myself, but I remember I read it somewhere a long time ago that in treemacs logic:

  • if you are using it for the first time, i.e., you've never manually added a project, treemacs will display the entire filesystem.
  • otherwise, treemacs will become a project/workspace based navigation system.

Since you've mentioned that you are an "emacs newbie" 😛, there is a chance that you've never added a project.

To add a project, do M-x treemacs-add-project and see if it behaves as you wish.
