Is your feature request related to a problem? Please describe.
I would like to run ASP Core application in one of the command:
public static async Task Main(string[] args)
{
var app = new CommandApp<RunCommand>();
app.Configure(config =>
{
config.AddCommand<RunCommand>("db-migrate")
.WithDescription("Only starts database migrations and exits the application.");
config.AddCommand<RunCommand>("run")
.WithDescription("Runs ASP core application");
});
await app.RunAsync(args);
}But in this way, I'm not able to pass original args to my host:
public class RunCommand : AsyncCommand
{
public override async Task<int> ExecuteAsync(CommandContext context)
{
var host = Host.CreateDefaultBuilder(args) // <-- here I need the program arguments, but context contains only parsed list
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
}).Build();
await host.RunAsync();
return 0;
}
}So I tried use the AddDelegate method instead of AddCommand, but this method can't be async.
public static async Task Main(string[] args)
{
var app = new CommandApp<RunCommand>();
app.Configure(config =>
{
config.AddCommand<RunCommand>("db-migrate")
.WithDescription("Only starts database migrations and exits the application.");
config.AddDelegate("run", context => RunApplication(args)) //<-- the RunApplication method can'd be async
.WithDescription("Runs ASP core application");
});
await app.RunAsync(args);
}
public static async Task RunApplication(string[] args)
{
var host = Host.CreateDefaultBuilder(args) // <-- here I need the program arguments, but context contains only parsed list
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
}).Build();
await host.RunAsync();
}Describe the solution you'd like
This problem can be solved in two ways:
- Add original parameters to the command context:
public class RunCommand : AsyncCommand
{
public override async Task<int> ExecuteAsync(CommandContext context)
{
var args = context.OriginalArguments //<-- contains args from the main method
return 0;
}
}
- Support async deleget
AddDelegateAsync:
public static async Task Main(string[] args)
{
var app = new CommandApp<RunCommand>();
app.Configure(config =>
{
config.AddDelegateAsync("run", async context => await RunApplication(args)) //<-- the new AddDelegateAsync method
});
await app.RunAsync(args);
}
