It's not available on --without-x builds:
0. ./src/emacs -Q
1. M-x toggle-debug-on-error RET
2. M-x make-frame-on-display RET
Debugger entered--Lisp error: (void-function x-display-list)
What's TRT here?
(interactive (list (completing-read
(format "Make frame on display: ")
(if (fboundp 'x-display-list)
(x-display-list)
(user-error "No connected displays found")))))
This will barf before make-frame is called, and pacifies the
byte-compiler warning about x-display-list not being known.
(interactive (list (completing-read
(format "Make frame on display: ")
(and (fboundp 'x-display-list)
(x-display-list)))))
This will barf when make-frame is called, with e.g.:
make-frame: Don’t know how to interpret display ""
make-frame: Don’t know how to interpret display ":0"
And also pacifies the warning.
Any preferences or alternative suggestions?
Thanks,
