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

### Files
|
|
|
|
These are the files / directories that are created and/or modified with this
|
|
install:
|
|
|
|
```text
|
|
~/.config/envman/PATH.env
|
|
~/.local/opt/pwsh/

~/.local/share/powershell/Modules

## 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.
|
|
|
|
For example, if you want to create a `curl.exe -A "windows" | 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](../vim-ale/) installed - which is included with
|
|
[vim-essentials](../vim-essentials/) - all you need to do is install the
|
|
`PSScriptAnalyzer` module.
|
|
|
|
See the "Lint & Fmt" section below.
|
|
|
|
### How to Lint & Fmt ps1 Files
|
|
|
|
You must install `PSScriptAnalyzer`. Then you can use `Invoke-ScriptAnalyzer`
|
|
and `Invoke-Formatter`
|
|
|
|
```sh
|
|
pwsh -Command "Install-Module -Name PSScriptAnalyzer -Scope CurrentUser -AllowClobber"
|
|
```
|
|
|
|
To lint:
|
|
|
|
```sh
|
|
my_ps1='./my-file.ps1'
|
|
pwsh -Command "Invoke-ScriptAnalyzer -Fix -ExcludeRule PSAvoidUsingWriteHost, PSUseDeclaredVarsMoreThanAssignment -Path \"$my_ps1\""
|
|
```
|
|
|
|
To fmt:
|
|
|
|
```sh
|
|
my_ps1='./my-file.ps1'
|
|
my_text="$(
|
|
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.
