How to change the help subcommand to another one?

[lancelot96]

Can I replace the default help subcommand with another name?

E.g.

./app help foo

change to

./app boo foo

No. But you can disable it and write your own subcommand.

Thanks, I am using DisableHelpSubcommand, DisableHelpFlags and write a new subcommand, but I find that most of error will call try_help function to create error message which contains the string --help. Maybe it doesn't need to be called when DisableHelpFlags is enabled.

What do you mean? Can you give minimal sample code, the command you are trying to call it with, actual behaviour and expected behaviour?

[lancelot96]

App::new("test")
        .global_setting(AppSettings::DisableHelpFlags)
        .get_matches_from(vec!["test", "--help"]);

The output is

error: Found argument '--help' which wasn't expected, or isn't valid in this context

USAGE:
    test

For more information try --help

The is no --help option but the error message still print it.
