SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the creation of robust and user-friendly command-line interfaces (CLIs) for .NET applications, handling complex command structures, options, and arguments.

Core Features & Use Cases

  • Command Hierarchy: Define nested commands and subcommands for organized CLI structures.
  • Options & Arguments: Easily declare typed options (e.g., --output, -o) and positional arguments.
  • Custom Parsing & Validation: Implement custom logic for parsing complex types and validating input values.
  • Testing Utilities: Provides patterns for effectively testing CLI applications.
  • Use Case: Develop a CLI tool to manage cloud resources, allowing users to create, delete, and list instances with various configuration options.

Quick Start

Use the dotnet-system-commandline skill to create a new CLI application with a 'list' command that accepts a '--output' option.

FAQPage Schema
How do I build a .NET command line interface with nested commands and typed arguments?▼

Build a .NET command line interface using the System.CommandLine 2.0+ library to define complex command hierarchies, typed options, and positional arguments. It supports custom parsing logic and input validation for robust CLI applications.

What is the best way to parse and validate complex input types in a dotnet CLI application?▼

Parse and validate complex input types in a dotnet CLI by implementing custom parsing logic and validation rules provided by System.CommandLine. This ensures typed options and arguments are correctly processed before execution.

Does System.CommandLine work with .NET 8.0 and how do I set it up?▼

System.CommandLine works with .NET 8.0+ and requires adding the System.CommandLine NuGet package to your project. Once added, you can declare typed options and define nested commands for your CLI structure.

Can I test .NET CLI applications that use System.CommandLine for argument parsing?▼

You can test .NET CLI applications using provided testing patterns and utilities designed for System.CommandLine. This allows you to verify command hierarchies, argument parsing, and validation logic effectively.

How do I structure subcommands like create and delete for a cloud resource management CLI in .NET?▼

Structure subcommands for a .NET CLI by defining nested command hierarchies using System.CommandLine. This allows you to organize commands like create, delete, and list, while attaching typed options such as --output to each.

Why use System.CommandLine over manual argument parsing in a .NET application?▼

Use System.CommandLine instead of manual argument parsing to simplify handling complex command structures, typed options, and custom validation. It reduces boilerplate and provides testing utilities for robust CLI development.
