Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.
The ScriptTask must contain a single code
element, which in turn contains the script code.
This code can include extensions such as functions, or tasks. Once the script task has executed those extensions will be available for use in the buildfile.
If no extensions have been defined, a static entry point named ScriptMain
- which must have a single Project argument - is required.
The following namespaces are imported by default:
The assembly references that are specified will be used to compile the script, and will be loaded into the NAnt appdomain.
By default, only the NAnt.Core
and mscorlib
assemblies are referenced.
Run C# code that writes a message to the build log.
<script language="C#"> <code> <![CDATA[ public static void ScriptMain(Project project) { project.Log(Level.Info, "Hello World from a script task using C#"); } ]]> </code> </script>
Define a custom function and call it using C#.
<script language="C#" prefix="test" > <code> <![CDATA[ [Function("test-func")] public static string Testfunc( ) { return "some result !!!!!!!!"; } ]]> </code> </script> <echo message='${test::test-func()}'/>
Use a custom namespace in C# to create a database
<script language="C#" > <references> <include name="System.Data.dll" /> </references> <imports> <import namespace="System.Data.SqlClient" /> </imports> <code> <![CDATA[ public static void ScriptMain(Project project) { string dbUserName = "nant"; string dbPassword = "nant"; string dbServer = "(local)"; string dbDatabaseName = "NAntSample"; string connectionString = String.Format("Server={0};uid={1};pwd={2};", dbServer, dbUserName, dbPassword); SqlConnection connection = new SqlConnection(connectionString); string createDbQuery = "CREATE DATABASE " + dbDatabaseName; SqlCommand createDatabaseCommand = new SqlCommand(createDbQuery); createDatabaseCommand.Connection = connection; connection.Open(); try { createDatabaseCommand.ExecuteNonQuery(); project.Log(Level.Info, "Database added successfully: " + dbDatabaseName); } catch (Exception e) { project.Log(Level.Error, e.ToString()); } finally { connection.Close(); } } ]]> </code> </script>
Run Visual Basic.NET code that writes a message to the build log.
<script language="VB"> <code> <![CDATA[ Public Shared Sub ScriptMain(project As Project) project.Log(Level.Info, "Hello World from a script task using Visual Basic.NET") End Sub ]]> </code> </script>
Define a custom task and call it using C#.
<script language="C#" prefix="test" > <code> <![CDATA[ [TaskName("usertask")] public class TestTask : Task { #region Private Instance Fields private string _message; #endregion Private Instance Fields #region Public Instance Properties [TaskAttribute("message", Required=true)] public string FileName { get { return _message; } set { _message = value; } } #endregion Public Instance Properties #region Override implementation of Task protected override void ExecuteTask() { Log(Level.Info, _message.ToUpper()); } #endregion Override implementation of Task } ]]> </code> </script> <usertask message='Hello from UserTask'/>
Define a custom function and call it using Boo.
<script language="Boo.CodeDom.BooCodeProvider, Boo.CodeDom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=32c39770e9a21a67" failonerror="true"> <code> <![CDATA[ [Function("test-func")] def MyFunc(): return "Hello from Boo !!!!!!" ]]> </code> </script> <echo message='${script::test-func()}'/>
