Cake script runner

When using Cake .NET Tool, Cake runner for .NET Framework or Cake runner for .NET Core you can use the following methods to control setup and teardown.

Global lifetime

If you want to do something before the first or after the last task has been run, you can use Setup and Teardown. A use case for this might be when you need to start some kind of server and want to make sure it gets torn down properly.

Setup(context =>
{
    // Executed BEFORE the first task.
});

Teardown(context =>
{
    // Executed AFTER the last task.
});

Setup will only be called if a call to RunTarget is made and the dependency graph is correct. If Cake doesn't run any tasks, neither Setup or Teardown will be called.

Task lifetime

You can also use TaskSetup and TaskTeardown if you want to do something before and after each task is run. A use case for this might be when you need to use custom logging for each task executed

TaskSetup(setupContext =>
{
    var message = string.Format("Task: {0}", setupContext.Task.Name);
    // custom logging
});

TaskTeardown(teardownContext =>
{
    var message = string.Format("Task: {0}", teardownContext.Task.Name);
    // custom logging
});

Cake Frosting

When using Cake Frosting you can implement the following methods.

Global lifetime

Implement an IFrostingLife to control global lifetime and register it with UseLifetime on the Cake host. There are two base implementation which you can inherit: FrostingLifetime and FrostingLifetime<TContext>.

The following example shows a lifetime implementation for a script with a build context of type BuildContext:

public static class Program
{
    public static int Main(string[] args)
    {
        return new CakeHost()
            .UseContext<BuildContext>()
            .UseLifetime<BuildLifetime>()
            .Run(args);
    }
}

public class BuildLifetime : FrostingLifetime<BuildContext>
{
    public override void Setup(BuildContext context)
    {
        // Executed BEFORE the first task.
    }

    public override void Teardown(BuildContext context)
    {
        // Executed AFTER the last task.
    }
}

Task lifetime

Implement an IFrostingTaskLife to control task lifetime and register it with UseTaskLifetime on the Cake host. There are two base implementation which you can inherit: FrostingTaskLifetime and FrostingTaskLifetime<TContext>.

The following example shows a lifetime implementation for a script with a build context of type BuildContext:

public static class Program
{
    public static int Main(string[] args)
    {
        return new CakeHost()
            .UseContext<BuildContext>()
            .UseTaskLifetime<TaskLifetime>()
            .Run(args);
    }
}

public class TaskLifetime : FrostingTaskLifetime<BuildContext>
{
    public override void Setup(BuildContext context, ITaskSetupContext info)
    {
        // Executed BEFORE every task.
    }

    public override void Teardown(BuildContext context, ITaskTeardownContext info)
    {
        // Executed AFTER every task.
    }
}
