Question 1

How to handle subcommands with EntryPoint?

Accepted Answer

Define a class inheriting from BaseCliCommands with methods decorated with [Command] attributes, then use Cli.Execute to parse and run commands, as shown in the example implementation on GitHub.

Question 2

Does EntryPoint support .NET Core?

Accepted Answer

Yes, EntryPoint targets .NET Standard 1.6+, which includes .NET Core and all future .NET releases, ensuring full cross-platform compatibility for modern .NET applications.

Question 3

EntryPoint vs CommandLineParser for .NET?

Accepted Answer

EntryPoint offers a more declarative, attribute-based approach with POCOs, reducing boilerplate, while CommandLineParser has a larger ecosystem and more features like automatic help. Choose EntryPoint for simplicity and standards compliance.

Question 4

Can EntryPoint parse optional arguments and flags?

Accepted Answer

Yes, it supports options with both short and long names using [Option] attributes, allowing flexible parsing of flags and values as per IEEE standards with extensions for --option style.

Question 5

What's the performance impact of using EntryPoint?

Accepted Answer

EntryPoint is lightweight and designed for efficiency, but the reflection used in attribute parsing might introduce minor overhead compared to hand-rolled solutions, though it's negligible for most CLI applications.

Question 6

How to validate arguments in EntryPoint?

Accepted Answer

Validation is typically handled manually in the POCO properties or after parsing, as the library focuses on parsing rather than built-in validation; you can add custom logic in setters or post-parse checks.
