Project.el - running processes in root

[Theodor Thornhill <theo@thornhill.no>]

Hello!

What is the best way to run a subprocess in root of a project currently?

Right now I've made a small convenience macro for this:

(defmacro with-project-root (&rest body)
  "Dynamically bind default directory to project root."
  (declare (debug t) (indent 0))
  `(let ((default-directory (project-root (project-current))))
     ,@body))


Then I can:

(defun elm-repl ()
  "Create a new buffer with Elm repl started and switch to it."
  (interactive)
  (with-project-root
    (switch-to-buffer-other-window
     (make-comint "Elm Repl" "elm" nil "repl"))))

This seems like a nice solution, but if there already exists something like
this, please tell.  Otherwise, would this be something appropriate for
project.el to expose?

Have a nice day,

Theo
