Procédure pas à pas : création d'un hôte de modèle de texte personnalisé
Un hôte de modèle de texte fournit un environnement qui permet au moteur de transformation de modèle de texte de fonctionner.L'hôte est chargé de gérer l'interaction du moteur avec le système de fichiers.Le moteur ou processeur de directive qui a besoin d'un fichier ou d'un assembly peut demander une ressource à l'hôte.L'hôte peut ensuite effectuer des recherches dans les répertoires et le Global Assembly Cache pour trouver la ressource demandée.Pour plus d'informations, consultez Processus de transformation du modèle de texte.
Vous pouvez écrire un hôte personnalisé si vous souhaitez utiliser les fonctionnalités de transformation de modèle de texte depuis l'extérieur de Visual Studio ou si vous souhaitez intégrer ces fonctionnalités dans des outils personnalisés. Pour créer un hôte personnalisé, vous devez créer une classe qui hérite de ITextTemplatingEngineHost.Pour obtenir la documentation de méthodes individuelles, consultez ITextTemplatingEngineHost.

Si vous écrivez une extension ou un package Visual Studio, envisagez d'utiliser le service de création de modèles de texte au lieu de créer votre propre hôte.Pour plus d'informations, consultez Appel d'une transformation de texte dans une extension VS. |
Cette procédure pas à pas décrit les tâches suivantes :
Création d'un hôte de modèle de texte personnalisé.
Test de l'hôte personnalisé.
Composants requis
Pour effectuer cette procédure pas à pas, vous devez disposer des éléments suivants :
Visual Studio 2010
Visual Studio 2010 SDK
Création d'un hôte de modèle de texte personnalisé
Dans cette procédure pas à pas, vous allez créer un hôte personnalisé dans une application exécutable qui peut être appelée à partir de la ligne de commande.L'application accepte un fichier modèle de texte comme argument, lit le modèle, appelle le moteur pour transformer le modèle et affiche toutes les erreurs qui se produisent dans la fenêtre d'invite de commandes.
Pour créer un hôte personnalisé
Dans Visual Studio, créez une application console Visual Basic ou C# nommée CustomHost.
Ajoutez une référence aux assemblys suivants :
Microsoft.VisualStudio.TextTemplating.11.0
Microsoft.VisualStudio.TextTemplating.Interfaces.11.0

Test de l'hôte personnalisé
Pour tester l'hôte personnalisé, vous allez écrire un modèle de texte, puis exécuter l'hôte personnalisé, lui passer le nom du modèle de texte et vérifier que le modèle est transformé.
Pour créer un modèle de texte pour tester l'hôte personnalisé
Créez un fichier texte et nommez-le TestTemplate.tt.
Vous pouvez utiliser n'importe quel éditeur de texte (tel que le Bloc-notes) pour créer le fichier.
Ajoutez le code suivant au fichier :
[!REMARQUE]
Le langage de programmation du modèle de texte ne doit pas nécessairement correspondre à celui de l'hôte personnalisé.
Text Template Host Test <#@ template debug="true" #> <# //Uncomment this line to test that the host allows the engine to set the extension. #> <# //@ output extension=".htm" #> <# //Uncomment this line if you want to debug the generated transformation class. #> <# //System.Diagnostics.Debugger.Break(); #> <# for (int i=0; i<3; i++) { WriteLine("This is a test"); } #>Text Template Host Test <#@ template debug="true" language="VB"#> <# 'Uncomment this line to test that the host allows the engine to set the extension. #> <# '@ output extension=".htm" #> <# 'Uncomment this line if you want to debug the generated transformation class. #> <# 'System.Diagnostics.Debugger.Break() #> <# Dim i As Integer For i = 0 To 2 WriteLine("This is a test") Next #>Enregistrez et fermez le fichier.
Pour tester l'hôte personnalisé
Ouvrez la fenêtre Invite de commandes.
Tapez le chemin d'accès du fichier exécutable de l'hôte personnalisé, mais n'appuyez pas encore sur ENTRÉE.
Par exemple, tapez :
<YOUR PATH>CustomHost\bin\Debug\CustomHost.exe
[!REMARQUE]
Au lieu de taper l'adresse, vous pouvez rechercher le fichier CustomHost.exe dans l'Explorateur Windows, puis le faire glisser dans la fenêtre d'invite de commandes.
Tapez un espace.
Tapez le chemin d'accès du fichier modèle de texte, puis appuyez sur ENTRÉE.
Par exemple, tapez :
C:\<YOUR PATH>TestTemplate.tt
[!REMARQUE]
Au lieu de taper l'adresse, vous pouvez rechercher le fichier TestTemplate.tt dans l'Explorateur Windows, puis le faire glisser dans la fenêtre d'invite de commandes.
L'application hôte personnalisée s'exécute et accomplit le processus de transformation du modèle de texte.
Dans l'Explorateur Windows, recherchez le dossier qui contient le fichier TestTemplate.tt.
Ce dossier inclut également le fichier TestTemplate1.txt.
Ouvrez ce fichier pour afficher les résultats de la transformation du modèle de texte.
La sortie de texte générée qui apparaît se présente comme suit :
