Pre-Commit hook for git that will fix my user.email setting for me

pre-commit

#!C:\Program\ Files\PowerShell\6.0.0\pwsh.exe -File

$Pattern = '^origin\s+https://(\S+)\s\(push\)'
$Origin = (& 'git' 'remote' '-v') -match $Pattern | Where-Object -FilterScript {$_ -is [string]}
$RemoteDomain = if($Origin -match $Pattern) {$Matches[1]}
$Email = & 'git' 'config' '--get' 'user.email' | Where-Object -FilterScript {$_ -is [string]}
$DesiredEmail = switch -Wildcard ($RemoteDomain) {
    'simonwahlin.visualstudio.com*' {
        '[email protected]'
        break
    }
    'advaniase.visualstudio.com*' {
        '[email protected]'
        break
    }
    'github.com*' {
        '[email protected]'
        break
    }
}

if($Email -ne $DesiredEmail) {
    Write-Warning -Message 'WRONG EMAIL!'
    Write-Warning -Message "Changing to: $DesiredEmail"
    & 'git' 'config' 'user.email' $DesiredEmail
}

@SimonWahlin I can't get the shebang to work as you've specified it. The PowerShell script is ignored until after the commit and then i get a prompt to open a text file. When I select notepad, the pre-commit script opens in it.

I have been able to get this to work:

#!/bin/sh
pwsh.exe -NoProfile -ExecutionPolicy Bypass -File .git/hooks/pre-commit.ps1

But it would be nice not to have to invoke sh just to launch PowerShell.

Hmm, just tried this again with your approach and it works. Go figure.

BTW I settled on this approach because I didn't like the brittleness of specifying the path to pwsh.exe on Windows:

#!/usr/bin/env pwsh

The only downside is that this still runs your profile scripts which in my case can really slow down processing of commits. I ended up putting this in my profile script for now:

# If run as part of a pre-commit hook do not run rest of profile
if (Test-Path Env:\GIT_INDEX_FILE) { return }
