This should only check the very first directory, right? I don't know if tilda can be in the middle...

I'd expect that we expand tilde for all elements. There are other applications which add their paths.

My intent here is to only handle the beginning case which is the most common case. ~ in the middle doesn't make sense.

There are potentially other PATH values where we might want to apply this as well. I don't recall the exact names off the top of my head, but don't Mac and Linux have PATH-type environment variables that dictate where to look for native library dependencies to load? |

I guess it is tabs here and below. Please fix indentations.

I noticed the file was mixed formatting, I'll reformat the entire file.

From https://github.com/dotnet/cli/issues/9321 I see that only $HOME works for zsh and MacOs. |

@vexx32, you're thinking of |

@SteveL-MSFT yeah I understand that. My concern is simply that we will now have two separate ways we handle the one "kind" of environment variable. It's certainly not desirable to promote this oddity too much, I'll agree, but I wonder whether it's better / simpler to be consistent here and have a single way of handling at least initial path resolution for paths in these variables? |
|
I think we need to document the feature. |

LGTM but maybe open an issue to support Tilda in other PATH-like variables.

PR Summary
The
~meaning user home path is a commonly used convention. Bash (and compatible shells) expands this automatically (along with other derivatives not covered in this PR). Dotnet global tools sets $env:PATH with a path to the tools starting with~. In PowerShell, that is treated as a literal so the tools aren't found. Fix is in command discovery, when processing $env:PATH, handle the case where a sub-path starts with~/or just contains~and expand it to be the user home path.PR Context
Fix #11531
