Question 1

How do I create multiple commands like git push and pull in PowerArgs?

Accepted Answer

Use the [ArgActionMethod] attribute on methods in your class. PowerArgs will automatically invoke the correct method based on the first argument, as demonstrated in the calculator program with separate add, subtract, multiply, and divide actions.

Question 2

PowerArgs vs System.CommandLine – which is better for .NET?

Accepted Answer

PowerArgs excels for complex, action-based CLI tools with built-in validation and tab completion, while System.CommandLine might be lighter for simpler parsing needs. Choose based on whether you need advanced features like customizable help templates.

Question 3

How to add custom validation rules in PowerArgs?

Accepted Answer

Create a class that derives from ArgValidator and apply it as an attribute to properties. The README shows an example with [UsPhoneNumber], and you can implement similar validators for specific business logic.

Question 4

Can PowerArgs generate HTML help documentation?

Accepted Answer

Yes, it includes a browser-friendly usage template that outputs HTML. You can use ArgUsage.GenerateUsageFromTemplate() with the built-in web template or create custom ones, as linked in the README example.

Question 5

How to handle secure inputs like passwords with PowerArgs?

Accepted Answer

Use the SecureStringArgument type for properties. It prompts users without displaying input, and you can access the value via the SecureString property or ConvertToNonsecureString method, ensuring sensitive data isn't visible on the command line.
