Open in new tab in running Carbon Emacs
Carbon Emacs acts like emacsclient or gnuserv by itself, i.e. it only runs one instance and opens files in this instance from Finder automatically.
A drawback of this behaviour is that the usual server-window variable of gnuserv has no effect. When using elscreen to get tabs into Emacs the desired behaviour might be to open a new tab in the running Emacs when you open a file from Finder. This can easily be done, using my intelligent-kill command (see my elscreen posting) such that files from Finder are opened in a new tab, and you can close this tab with the usual C-x C-c:
(message "New tab")
(elscreen-create))
(defadvice mac-ae-open-documents (before mac-ae-open-documents-advice activate)
"Create new tab before" (create-new-tab-and-switch-to))
(ad-activate ‘mac-ae-open-documents)
