Emacs：在.emacs中检查无窗口系统

Question

is it possible, to check if emacs is running in --no-window-system ( -nw ) mode within the dot-emacs file ( .emacs )? I would like to enable/include certain extension only if emacs is in window mode (/or not).

Kind regards, mefiX

Answer 1

如果所选帧位于纯文本终端上，则变量window-system nil 。

Answer 2

Put the code you want to run when emacs executes in a windowed environment inside a when block and use the display-graphic-p predicate ie

(when (display-graphic-p)
  (do something)
  (do-another-thing))

or reverse
