Getting Started

Installation

dotnet add package ArgSharpCLI

Basic Usage

The following example demonstrates adding a simple TestCommand class and executing it.

using ArgSharpCLI;

// Define a simple command
[Command(Name = "test")]
public class TestCommand : ICommand
{
    [Option("test-option", "t", "test option")]
    public string? TestOption { get; set; }

    [Option("test-boolean-option", "b", "test boolean option")]
    public bool TestBooleanOption { get; set; }
}

// In your Main method
var command = new CommandBuilder()
    .AddArguments(args)
    .AddCommand<TestCommand>()
    .Build();

// Execute the built command
command.Match(
    onSuccess: cmd => cmd.Run(),
    onFailure: err => Console.WriteLine($"Error: {err}")
);

Advanced Usage

You can organize your commands into sub-commands as shown below:

using ArgSharpCLI;

// Define the main command
[Command(Name = "main")]
public class MainCommand : ICommand
{
    // Implementation here
}

// Define a sub-command
[Command(Name = "sub")]
public class SubCommand : ICommand
{
    // Implementation here
}

// In your Main method
var command = new CommandBuilder()
    .AddArguments(args)
    .AddCommand<MainCommand>(cmd => {
        cmd.AddSubCommand<SubCommand>();
    })
    .Build();

// Execute the command
// Execute the built command
command.Match(
    onSuccess: cmd => cmd.Run(),
    onFailure: err => Console.WriteLine($"Error: {err}")
);
