How to output help text in validation method

[wayneyaoo]

Hi team,

Is there anyway I can output help text when 0 arguments are given so that people don't have to use -h explicitly? e.g., simple git won't give you error but output help text.

I can imagine something like this

        public override ValidationResult Validate(CommandContext context, DefaultCommandCommandSetting settings)
        {
            if (context.Remaining.Parsed.Count == 0)
            {
                     return ValidationResult.Error(SomeHelpTextOfCurrentVerb)
            }
            ...
        }

any recommendation for this?

I skim through the code and .. it seems that HelpWriter is the one that does heavy lifting under the hood, and the CommandModel it writes is internal and not open to configure.

So that basically is no. Currently it doesn't have a way to achieve such behavior.
