Use They can easily be emulated. Rather than calling `make-variable-frame-local' and accessing the variable value directly, explicitly check for a frame-parameter, and if there is one, use its value in preference to -that of the variable. Eg: -(let ((fp (assoc 'var (frame-parameters)))) - ;; Use frame-parameter, even if nil. - (if fp (cdr fp) - ;; Else use normal variable value. - var)) +that of the variable. Note that buffer-local values should take +preference over frame-local ones, so you may wish to check `local-variable-p' +first. ** The function invisible-p returns non-nil if the character after a specified position is invisible. -- 2.39.2
