Sigh ...
some basic lisp, I'm afraid, but I did consult the manual and tested
in lisp-interaction-mode, but did not get any the wiser.
I'm trying to get a function to work differently depending on whether
emacs runs under X or on a terminal:
(if (eq window-system nil)
; running under a terminal
(lambda ()
(split-window)
(switch-to-buffer "*foo*")
)
; running under a window system
(lambda ()
(select-frame (make-frame))
(set-frame-size (selected-frame) 50 24)
(set-frame-position (selected-frame) 150 120)
))
It seems that everything in the lambda expressions is ignored
(i.e. nothing happens). I used these lambda expressions because
simply putting a body of functions got error messages about "Invalid
function"s. But it seems I don't get these right.
(lambda (
(split-window)
(switch-to-buffer "*foo*")
))
also seems to be valid syntax, but is also ignored.
Can anybody help how to get this simple conditional to work?
