Rules to Better Command Lines

There should never be a command line utility without a UI. Take an example of Visual Studio 2008:

It is always a good practice to have UI opened when specifying \[ApplicationName].exe from command line. If the GUI is not done, show a messagebox "GUI coming...".

Note: If you prefer for not putting UI as the default, it should have be at least "/GUI" as the argument. Do not use "/i", because too many command lines are using “/i” already.

When you develop an application that supports command line, you must provide a list of arguments / help on how to use the application through command line.

It can be as easy as typing: \[ApplicationName].exe /? for listing the arguments.

When building command line applications in .NET, you need a framework that makes argument parsing, validation, and help generation simple and intuitive. Cocona is a lightweight and powerful framework that turns your C# methods into fully-featured CLI commands with minimal boilerplate code.

Cocona has many built-in features that make it feel familiar to .NET developers.

Why use Cocona?

Cocona offers several advantages over manual argument parsing or other CLI frameworks:

• Simple and intuitive: Transform regular C# methods into CLI commands
• Automatic help generation: Built-in help text and usage information
• Type safety: Strong typing for command parameters and options
• Dependency injection: Built-in DI container support
• Validation support: Integration with data annotations for parameter validation
• Async support: First-class support for async/await patterns
• Multiple commands: Easy support for sub-commands and complex CLI structures

Windows Terminal is a modern terminal application that allows users to manage multiple command-line tools from a single interface. One standout feature is the ability to split the main window into multiple panes, enabling the running and viewing of multiple sessions side by side within a single window.
