扩展带有前缀“~"的 POSIX 路径；(使用 AppleScript) [英] Expand a POSIX path with prefix "~" (using AppleScript)

问题描述

StandardAdditions 有 path to 命令，我们可以使用它来获取已知位置.

StandardAdditions has the path to command and we can use it to get known locations.

例如，path to home folder 返回对user folder 的文件引用，如果我们想要posix path，我们可以这样做((主文件夹的路径)作为文本)的 POSIX 路径.

For example, path to home folder returns a file reference to the user folder and if we want the posix path, we can do POSIX path of ((path to home folder) as text).

在Terminal.app中，我们可以使用波浪号(~)来表示home文件夹.

In Terminal.app we can use the tilde character (~) to represent the home folder.

我们如何在 AppleScript 中执行此 波浪号扩展?

How can we do this tilde expanding in AppleScript?

推荐答案

从 OS X 10.10 开始，您可以轻松访问 Cocoa 类 及其功能和属性:

Started with OS X 10.10 you can easily access Cocoa classes and their functions and properties:

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 中，您必须在 Scripting Libraries 中定义这样的处理程序，这并不像听起来那么好.但在 10.10 中，这是开箱即用的！

In 10.9 you have to define such handlers in Scripting Libraries, that's less nice than it sounds. But in 10.10 this works out of the box!
