system-type变量：
system-type is a variable defined in `C source code'.
Its value is darwin
Documentation:
Value is symbol indicating type of operating system you are using.
Special values:
`gnu' compiled for a GNU Hurd system.
`gnu/linux' compiled for a GNU/Linux system.
`darwin' compiled for Darwin (GNU-Darwin, Mac OS X, ...).
`ms-dos' compiled as an MS-DOS application.
`windows-nt' compiled as a native W32 application.
`cygwin' compiled using the Cygwin library.
Anything else indicates some sort of Unix system.Stack Overflow用户

对于刚接触elisp的人来说，示例用法如下：
(if (eq system-type 'darwin)
; something for OS X if true
; optional something if not

我创建了一个简单的宏，以便根据系统类型轻松运行代码：
(defmacro with-system (type &rest body)
"Evaluate BODY if `system-type' equals TYPE."
(declare (indent defun))
`(when (eq system-type ',type)
,@body))
(with-system gnu/linux
(message "Free as in Beer")
(message "Free as in Freedom!"))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
