PowerShell 选项卡完成问题
假设我有以下文件夹：C:\[test]\x，那么，当在 [test] 文件夹内时，我无法使用 PowerShell 的 Tab 补全功能全部。
我猜原因是文件夹名称需要转义为 ´[test´] （刻度线颠倒，这会导致此处的 Markdown 问题），就像从 Tab 键切换时完成的那样在 C:\ 内。
我并不真正关心在 C:\ 内部并输入 [t... 时缺少的制表符补全，但我想在其中使用制表符补全文件夹。有什么办法可以解决这种行为吗？
Suppose I have the following folder: C:\[test]\x, then, when inside of the [test] folder, I can't use PowerShell's tab completion at all.
I guess the reason for that is that the folder name would need to be escaped to ´[test´] (with the ticks inverted, which causes Markdown problems here), as it the completion does when tabbing from inside C:\.
I don't really care about the missing tab completion when inside of C:\ and typing [t..., but I would like to use the tab completion within that folder. Is there any way to fix that behaviour?

PowerShell 及其许多功能通常不适用于带有特殊符号、
[和]符号的路径。我们无法修复 PowerShell 核心，但我们可以修复/替换某些功能。 TabExpansion 就是其中之一。它只是一个全局函数，可以用改进的实现来替换。可以到处找到几个自定义 TabExpansion 实现。我用的是我自己的。它与主机无关（至少它与控制台、ISE 和我自己的主机配合得很好），它相当简单，但它提供了很多改进。您的具体问题也已解决。
TabExpansion 的代码（点源代码或简单地从您的 PowerShell 配置文件中调用它）：
http://code.google.com/p/farnet /source/browse/trunk/PowerShellFar/TabExpansion.ps1
此测试涵盖了它的一些功能：
http://code。 google.com/p/farnet/source/browse/trunk/PowerShellFar/Bench/Test/Test-TabExpansion-.ps1
（测试仅在特殊环境下有效，不要运行，只需看一下代码中的注释，看看TabExpansion能做什么）。
PowerShell and many its features in general do not work well with paths with special symbols,
[and]symbols in the first place. We cannot fix the PowerShell core but we can fix/replace some features. TabExpansion is one of them. It's just a global function that can be replaced with an improved implementation.Several custom TabExpansion implementations can be found here and there. I am using my own. It is host agnostic (at least its works well with Console, ISE, and my own host), it is reasonably simple and yet it provides a lot of improvements. Your particular problem is resolved, too.
The code of TabExpansion (dot-source it in or simply call it from your PowerShell profile):
http://code.google.com/p/farnet/source/browse/trunk/PowerShellFar/TabExpansion.ps1
Some of its features are covered by this test:
http://code.google.com/p/farnet/source/browse/trunk/PowerShellFar/Bench/Test/Test-TabExpansion-.ps1
(The test works only in the special environment, do not run it, just take a look at comments in the code to see what TabExpansion can do).
