Was going to do this to recompile all our coffee scripts when they change, but found a better way

Foo.ps1

task Start-Coffee-Watcher -Description "when a coffee file changes recompile - for testing" {

  Start-Job -Name "CoffeeWatcher" -ArgumentList "$srcDir\WebRole\scripts" -ScriptBlock {
    param($scriptsFolder)

    Write-Host "Watching $scriptsFolder"

    $recompile = {
      # TODO: Figure out how to recompile coffee scripts from command line with SassAndCoffee
    }

    $scriptsFileSystemWatcher = New-Object io.FileSystemWatcher -Property @{
      Path = $scriptsFolder
      Filter = '*.coffee'
      IncludeSubdirectories = $true
      NotifyFilter = [io.NotifyFilters]'FileName, LastWrite'
      EnableRaisingEvents = $true
    }

    $onCreate = Register-ObjectEvent $scriptsFileSystemWatcher Created -SourceIdentifier FileCreated -Action {
      & $recompile
    }

    $onChange = Register-ObjectEvent $scriptsFileSystemWatcher Changed -SourceIdentifier FileChanged -Action {
      & $recompile
    }

    while ($true) { Sleep 100; Get-Event }
  }
}

task Stop-Coffee-Watcher {
  Stop-Job -Name "CoffeeWatcher"
}
