Hi, thank you for your reply.

After some searching and reading docs I changed the code to

(defun set-project-in-frame-title ()
  (interactive)
  ;;(select-frame frame)
  (setq projectname (getenv "project"))
  (message "Project: %s" projectname)
  (if projectname
      (modify-frame-parameters nil (list (cons 'title (concat
(buffer-name) " [" projectname "]"))))
    (modify-frame-parameters frame (list (cons 'title (buffer-name))))
    ) ;; if projectname
)

But it doesn't really make any difference. I figured out however, that I
probably need a hook to be executed when a frame is opened:

(add-hook 'after-make-frame-functions 'set-project-in-frame-title)


But, this doesn't work exactly right either. I get the buffer-name of the
previous buffer. E.g. when I start emacs:

export projectname="myproject"
emacs myfile

The frame title has:

*scratch* [myproject]

In the documentation of after-make-frame-functions it is claimed that the
new frame is passed as an argument, but when I do:
(defun set-project-in-frame-title (frame)
  (interactive)
  (select-frame frame)
  (setq projectname (getenv "project"))
  (message "Project: %s" projectname)
  (if projectname
      (modify-frame-parameters frame (list (cons 'title (concat
(buffer-name) " [" projectname "]"))))
    (modify-frame-parameters frame (list (cons 'title (buffer-name))))
    ) ;; if projectname
)

I get an error:
Wrong number of arguments: (lambda (frame) (interactive) (select-frame
frame) (setq projectname (getenv project)) (message Project: %s
projectname) (if projectname (modify-frame-parameters frame (list (cons
(quote title) (concat (buffer-name)  [ projectname ]))))
(modify-frame-parameters frame (list (cons (quote title)
(buffer-name)))))), 0

Thank you very much for any help,

Ian.
