PowerShell Core is a cross-platform (Windows, Linux, and macOS) automation and configuration tool/framework.

To update or switch versions, run webi pwsh@stable (or @v7.4, @beta, etc).

Cheat Sheet

The core benefit of running pwsh on Mac or Linux is that you get a way to debug Windows scripts without having to boot up Windows.

The core benefit of running pwsh on Windows is that it's years ahead of pre-installed version.

For example, if you want to create a curl.exe | powershell script for Windows (as we do), it's helpful to be able to do some level of debugging on other platforms.

How to Use PowerShell with Vim

Assuming you have vim-ale installed - which is included with vim-essentials - all you need to do is install the PSScriptAnalyzer module.

See the "Lint & Fmt" section below.

How to Use PowerShell with VSCode

VS Code should also automatically recognize and use PSScriptAnalyzer.

How to Lint, Fmt, & Fix ps1 Files

See pwsh-essentials for more info but, in short:

pwsh -Command "Install-Module -Name PSScriptAnalyzer -Scope CurrentUser -AllowClobber"
pwsh -Command "Invoke-ScriptAnalyzer -Fix -ExcludeRule PSAvoidUsingWriteHost -Path '$my_ps1'"

To fmt:

    pwsh -Command "Invoke-Formatter -ScriptDefinition (Get-Content -Path '$my_ps1' -Raw)"
printf '%s\n' "${my_text}" > "${my_ps1}"

Note: it is several hundred times faster to lint and fmt from a native PowerShell script than from invoking pwsh -Command each time.
