Question 1

How do I add command-line flags in acmd?

Accepted Answer

In acmd, flags are handled within the ExecFunc by parsing the args slice manually; for advanced flag parsing, you may need to integrate with other libraries, as acmd focuses on command execution rather than flag management. Check the GUIDE.md for basic examples.

Question 2

acmd vs cobra for Go CLI – which should I use?

Accepted Answer

acmd is better for simple, lightweight CLIs with minimal dependencies and a clean API, while cobra offers more features like subcommands, flag validation, and a larger ecosystem. Choose acmd for straightforward tools and cobra for complex applications.

Question 3

Can acmd handle multiple levels of subcommands?

Accepted Answer

acmd is designed for flat command structures and does not natively support nested subcommands. For hierarchical commands, you'd need to implement custom logic or consider a different library with built-in support.

Question 4

Is acmd suitable for large-scale CLI applications?

Accepted Answer

acmd is best for small to medium-sized tools; for large-scale applications with many commands and complex interactions, its minimalist approach might become limiting, and a more feature-rich framework would be preferable.

Question 5

How to set up command aliases in acmd?

Accepted Answer

Command aliases in acmd are set by specifying the Aliases field in the Command struct, allowing users to invoke commands with alternative names. This adds flexibility without requiring additional code.

Question 6

What error handling patterns does acmd support?

Accepted Answer

acmd uses Go's standard error handling: errors returned from ExecFunc are propagated and can be handled by the runner, with r.Exit(err) providing a way to exit with an error message for user feedback.
