展开前缀为"〜"的POSIX路径(使用AppleScript)

Question

StandardAdditions有path to命令,我们可以用它来获取已知的位置.

例如,path to home folder返回一个文件引用user folder,如果我们想要posix path,我们可以做POSIX path of ((path to home folder) as text).

在Terminal.app我们可以使用波浪号字符(~)来表示home folder.

入门OS X 10.10您可以轻松地访问Cocoa classes和它们的功能和特性:

use framework "Foundation"

expandTilde("~/Desktop")

on expandTilde(givenPath)
    -- create a temporary Obj-C/Cocoa NSString object with the givenPath
    set tempCocoaString to current application's NSString's stringWithString:givenPath
    -- call the object's stringByExpandingTildeInPath method
    -- to create a new path with expanded tilde
    return (tempCocoaString's stringByExpandingTildeInPath) as string
end expandTilde 

在10.9你必须定义这样的处理程序Scripting Libraries,这不如听起来好.但在10.10这个开箱即用的工作!
