Thanks for this interesting and valuable feedback

I know that, maybe my question should be the next one:

1. freeze cut.go --window will include --window.title=auto as is not explicitly written in the args.
2. freeze cut.go --window --window.title won't default to "auto" or be "" since it errors expecting a string.

Is there a way to use case 2 to behave like case 1? freeze cut.go --window --window.title defaulting to "auto" or after parsing being "", to act like a bool so if it is included defaults to "auto" or is "" and if --window.title="foo" after parsing would be "foo".

No, that is not possible.

Okay, thank you for answering 😁

@AlejandroSuero I usually have a pkg/infrastructure/cli/args_initialization.go with a InitializeArgs() function where I do read and modify os.Args. I called it from my main() function.

You can modify a --window.title to --window.title=auto, or add a --window.title=auto arg if it is missing, and if --window is present.

Then you can call kong.Parse(os.Args[1:])

It's an hack, but I like it anyway
Hack because, the app should allow to parse flag the way we want.

But thanks, it gives ideas
