Flag operation not as described

[FrankDMartinez]

Hi.

I hope you are having a great new year so far.

Using this package, I can create an application which has foo <command> {flags} as an option, great. The only commands I have are help and version, okay. When I pass any of my listed flags to either of these commands, I receive a message: Error: <flag name> is not a valid flag.

Could a change be made to not output the {flags} portion of foo <command> {flags} when the only commands are help and version?

Thanks in advance.

An alternative possibility would be to list help and version separately in the Usage section.

[FrankDMartinez]

For the alternative approach, the solution would include, in part, adding the following (or something like it) to the usageTemplate variable, I think:

{{- if .IsRootCommand }}{{ if .Commands }} {{ .Executable }} help{{ end }}{{ end -}}{{- if .IsRootCommand }}{{ if .Commands }} {{ .Executable }} version{{ end }}{{ end -}}

I am a bit unsure, though.

Come to think of it, the added text should just be:

{{ .Executable }} help
{{ .Executable }} version

Then, in the definition of type CommandRegistry struct, add a CommandsOtherThanHelpOrVersion bool and, in the definition of addCommand(name string), add cr.CommandsOtherThanHelpOrVersion = true. If you then replace "Commands" with "CommandsOtherThanHelpOrVersion" in the usageTemplate, I think it should just work.

Thoughts?
