This is a feature request.
Today, when running emacs server and no frames already exists,
emacsclient creates a terminal frame even when a window system is
available. The only way to make emacsclient create GUI frames is by
using the "-c" option which *always* creates a new frame, but negates
the desirable behavior of reusing existing frames.
I'd like to propose a new emacsclient option or an emacs
customizable variable so that the following pseudo-code happens when
invoking "emacsclient foo.txt" (or "emacsclient --new-option foo.txt"):
if (exist-frame)
open-buffer-in-existing-frame
else if (window-system-available)
open-buffer-in-new-GUI-frame
else
open-buffer-in-new-terminal-frame
There was also some discussion about this on r/emacs
(https://www.reddit.com/r/emacs/comments/8iq4ho/how_make_emacsclient_create_gui_frame_by_default/)
and I was directed at making this feature request.
