This seems to be a damned if they do and damned if they don't thing. There is another recent issue complaining that external windows exes don't understand ~ in a path. Tab expanding ~ helps to ensure a working path gets sent to things but it annoyed me until I grew used to it. There's probably a wider issue about making ~ work everywhere so that it can happily stay unexpanded by tab

As noted, with
~on Windows, when calling external programs, the behavior happens to be somewhat of a blessing currently, as~isn't automatically expanded on invocation.In general, however, I agree that the behavior is unhelpful:
Note that the problem is more general, in that it also affects (environment) variable-based paths; e.g., on Windows:

For the external programs issue, I would expect PowerShell should expand ~ from a PSPath (Temp: / ~) to a provider path (C:\temp) when calling external programs since they don't know what a PSPath is or may not have a concept of
~.This issue is specifically just for tab completion and command history so that what the user typed in is preserved. In my use case it creates a long command with the full path when I'm looking back and just need the relative path from
~.What prompted me originally to log this was when my custom PSDrive

Strange, you say this is happening in preview 4 but this was actually fixed in the preview 4 release by this PR: #19489
It works as expected on my PC:
Have you tried loading PS without a custom profile?
ThomasNieto commentedon Jul 27, 2023
MartinGC94 you're right, I must have accidently ran pwsh stable when the test with no profile. I can't reproduce on 7.4-preview 4. I can still reproduce the example using environment variables though. Did you fix that as well in your PR?
mklement0 commentedon Jul 27, 2023
MartinGC94, that's great news, but I can confirm Thomas Nieto (@ThomasNieto)'s finding that environment variables are still converted to literal paths.
Looking at your PR, I see that the issue at hand has a duplicate dating back to 2017:
Once the environment-variable issue is also handled, both this and the aforementioned issue should be closed.

Great, I was afraid there was some weird edge case I had missed. As for the variable replacement, I have some WIP code locally to fix that, I've just been too lazy to finish it. Expect to see a PR for that in the near future.

Closing as a duplicate of #5350.
