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
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 and many its features in general do not work well with paths with special symbols,
] 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):
Some of its features are covered by this test:
(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).
