Using bootstrapped paket

Ben Collins — Wed, 06 Dec 2017 15:04:54 +0000

I use the Paket package manager in several of my projects by bootstrapping, and so I wind up with a .paket directory at the root of my project folder which contains the paket.exe I need to use. I find it cumbersome to invoke it with relative paths like ../../../.paket/paket.exe, so I wrote a little bit of powershell to ensure the bootstrapped paket is in my path.

This is in the Cmder $PrePrompt function, but if you're not using Cmder, you can do this in the Prompt function of your Powershell profile (which you would have to add if you don't have it already. See about_Prompts for more info.

The relevant bits of my user-profile.ps1 set up for Cmder:

Function Get-AncestorPath ($dir, $name) {
    $target = Get-ChildItem $dir |? { $_.Name -eq $name }
    if ($target -ne $Null) {
        return $target
    } elseif ($dir.Parent -ne $Null) {
        return Get-AncestorPath $dir.Parent, $name
    } else {
        return $Null
    }
}

[ScriptBlock]$PrePrompt = {
    $paketDir = Get-AncestorPath $pwd ".paket" | Select-Object -ExpandProperty FullName
    if ($paketDir -eq $Null) {
        if ($Env:Path -like "*.paket*") {
            Write-Verbose "Removing .paket path from `$Env:Path"
            $Env:Path = $Env:Path -split ';' `
                |? { $_ -notlike "*.paket*" } `
                | Join-String -Separator ';'
        }
        return
    }

    Write-Verbose "Paket path: $paketDir"

    if (($Env:Path -split ';') -notcontains $paketDir) {
        Write-Verbose "Adding '$paketDir' to path..."
        $Env:Path = "$paketDir;$($Env:Path)"
    }
}

Running view compilation with a progress bar

Ben Collins — Tue, 31 Oct 2017 21:04:31 +0000

I ran into a build issue where view compilation failed on CI, but I didn't catch it because views aren't normally precompiled in developer builds. Here's what I wrote to check things out without having to do it manually:

$webdirs = gci -rec -Directory -Exclude "*node_modules*" `
  |? { ((Test-Path "$($_.FullName)\*.csproj") -eq $True) `
       -and ((Test-Path "$($_.FullName)\web.config") -eq $True) }

$webdirs |% {$idx = 0}{$pct = $idx/$projDirs.Length; `
  Write-Progress -Activity "Building Views" `
                 -Status ("{0:P}" -f $pct) `
                 -PercentComplete ($pct*100) `
                 -CurrentOperation "aspnet_compiler -v temp -p $($_.FullName)"; `
  aspnet_compiler -v temp -p $_.FullName; $idx++}

Upgrading C# in your Razor files with PowerShell

Ben Collins — Tue, 31 Oct 2017 16:26:01 +0000

git ls-files | sls web.config ` # get a list of web.config files here, but not with Get-ChildItem
  |% { (gc $_) -replace "/langversion:default","/langversion:latest" ` 
  | sc -Path $_ -Encoding UTF8 }

Deleting remote-pruned branches in Git with PowerShell

Ben Collins — Sun, 29 Oct 2017 21:11:34 +0000

It's easy to wind up with a substantial collection of branches that aren't on the remote anymore that keep Git's gc from cleaning up as much as it should. Let's get rid of them.

git branch -vv | sls gone `
  |% { $_.ToString().Trim() -split '\s+' | select -first 1 } `
  |% { git branch -D $_ }
