C#でWPF学習中「WPFプロジェクトを作成するスクリプト」

wpfプロジェクトを作る際、自分が良く使うパッケージの追加やソースファイルの作成、xamlの修正などをバッチ処理するPowerShellスクリプトを作成しました。

ファイル名:Create-WPFProj.ps1

<#
.SYNOPSIS
WPF用プロジェクトの作成

.DESCRIPTION
ReactivePropertyが使える状態のプロジェクトを作成
プロジェクト用ディレクトリを作成し移動した状態で実行のこと

.EXAMPLE

# XAML
$inFile = Join-Path (Get-location).Path "MainWindow.xaml"
$xmlDoc = [System.Xml.XmlDocument](Get-Content -Encoding UTF8 -Raw $inFile)

$ns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
$nslocal = "clr-namespace:${ProjectName}"
$nsi = "clr-namespace:Microsoft.Xaml.Behaviors;assembly=Microsoft.Xaml.Behaviors"
$nsinteractivity = "clr-namespace:Reactive.Bindings.Interactivity;assembly=ReactiveProperty.WPF"

$attri = $xmlDoc.CreateAttribute("xmlns:i")
$attri.Value = $nsi
$xmlDoc.Window.Attributes.Append($attri) | Out-Null

$attri2 = $xmlDoc.CreateAttribute("xmlns:interactivity")
$attri2.Value = $nsinteractivity
$xmlDoc.Window.Attributes.Append($attri) | Out-Null

$xmlDoc.Window.setAttribute("Title", "{Binding Title.Value}")

$child = $xmlDoc.CreateElement("Window.DataContext", $ns)
$child2 = $xmlDoc.CreateElement("local:MainWindowViewModel", $nslocal)

$pos = $xmlDoc.getElementsByTagName("Grid")[0]
$dc = $xmlDoc.Window.insertBefore($child, $pos)
$dc.appendChild($child2) | Out-Null


$child3 = $xmlDoc.CreateElement("i:Interaction.Behaviors", $nsi)
$child4 = $xmlDoc.CreateElement("local:ViewModelCleanupBehavior", $nslocal)

$ib = $xmlDoc.Window.insertBefore($child3, $pos)
$ib.appendChild($child4) | Out-Null

$xmlDoc.Save($inFile)

使い方

PowerShellを起動
プロジェクト用ディレクトリを作成
プロジェクト用ディレクトリに移動
上記スクリプトを実行

感想

WPFのプロジェクトを作るたび、同じことを繰り返していたので作成してみました。
毎度のことですがスクリプトの実用性は怪しいですが、PowerShellでXMLを加工する勉強になりました。
