Lazy Git Checkout with PowerShell

Some of the feature branch names of my current Git based project can get long at times. I was surprised at first that it didn’t seem I could use a wildcard for a branch name when switching branches with git checkout. That led me to creating the below PowerShell function that was a pretty quick and effective way of doing a checkout by wildcard.

function Set-Branch
{
    [CmdletBinding()]
    [Alias("Git-Checkout")]
    PARAM ( 
        [Parameter(Mandatory=$true, Position=0)] [string] $pattern
    )
    $branches = @(git branch `
        | Select-Object @{Name = "Name"; Expression = {$_.Replace("*", "").Trim()}} `
        | Where-Object {$_ -match $pattern})
    if ($branches.Length -ne 1) {
        Write-Warning "Expected 1 branch match but found $($branches.Length). Refine pattern."
        $branches
        return
    }
    $branch = $branches[0].Name
    git checkout $branch
}

Sample usage follows.

C:\source\myproject [Feature/ResourceLoading ≡]> git branch

  Feature/ConsoleTesterPort1-3                                                                                          
  Feature/CreateAdjustmentPage                                                                                          
* Feature/ResourceLoading                                                                                               
  Feature/ServingOptionsWC789                                                                                           
  Improvement/AllowUserToLockUnlockLocation                                                                             
  develop                                                                                                               
  master                                                                                                                
C:\source\myproject [Feature/ResourceLoading ≡]> set-branch allow                                                    
Switched to branch 'Improvement/AllowUserToLockUnlockLocation'                                                          
Your branch is behind 'origin/Improvement/AllowUserToLockUnlockLocation' by 34 commits, and can be fast-forwarded.      
  (use "git pull" to update your local branch)                                                                          
C:\source\myproject [Improvement/AllowUserToLockUnlockLocation ↓34]> 

I added this into my My-GitUtilities.psm1 module that I import when loading my PowerShell profile script.
