Jaahas.Spectre.Extensions 0.1.0

About

Jaahas.Spectre.Extensions is a collection of extensions for Spectre.Console.Cli to simplify integration of the Spectre CommandApp with Microsoft.Extensions.DependencyInjection.

Registering and Running a CommandApp

You can register a CommandApp with your host builder as follows:

var builder = Host.CreateApplicationBuilder(args);

builder.Services.AddSpectreCommandApp((IConfigurator options) => {
    // Configure your command app here.
});

return await builder.BuildAndRunCommandAppAsync(args);

You can use a CommandApp<TDefaultCommand> instead of a CommandApp by specifying the generic TDefaultCommand parameter when registering and running the command app:

var builder = Host.CreateApplicationBuilder(args);

builder.Services.AddSpectreCommandApp<MyDefaultCommand>((IConfigurator options) => {
    // Configure your command app here.
});

return await builder.BuildAndRunCommandAppAsync<MyDefaultCommand>(args);

The configured command app is capable of resolving services that the CommandApp or CommandApp<TDefaultCommand> registers with the Spectre ITypeRegistrar, or that have been registered directly with the service collection. For example, you can inject services such as ILogger<T> into your command classes.

You can also register the command app directly with an IServiceCollection and run it directly against the IServiceProvider built from the service collection if preferred.
