Middleware pipeline

Typin uses middleware pipeline to execute commands. By default it consists of CommandExecution. CommandExecution is always executed at the end of the pipeline, just before ICliMiddlewareExtensions.PipelineTermination action.

Writing custom middlewares

public sealed class CommandExecution : IMiddleware
{
    public CommandExecution()
    {

    }

    public async Task HandleAsync(ICliContext context, CommandPipelineHandlerDelegate next, CancellationToken cancellationToken)
    {
        context.Console.Output.WriteLine("-- Before command execution --");

        await next(context, cancellationToken);

        context.Console.Output.WriteLine("-- After command execution-- ");
    }
}
