Question - Custom HelpHooks about powerargs

[adamabdelhamed]

Is it possible that you have 2 help hooks registered in your argument definition? Without looking at your complete code I can't imagine how this can happen. Your override code is not calling the base method so that base code should not execute.

If you share your complete code I can take a look.

Thanks,

Thanks for getting back to me so quickly!

Yes, I did have two HelpHooks registered. I was trying both alongside each other to start with, with the Url one omitted from the usage:

        #region Global Options

        [HelpHook]
        [ArgShortcut("?")]
        public bool Help { get; set; }

        [ArgShortcut("~")]
        [OmitFromUsageDocs]
        [UrlHelpHook("myhelpurl.html")]
        public bool HelpUrl { get; set; }

        #endregion Global Options

So you can only have one?

At the moment, I have 3 action methods, with 4-6 arguments each - so the help text is getting too long for the console window.

Is there a way I could customise the usage, so that:

1. At the top level (i.e. with no action specified, so myapplication -?) it just listed the actions and global options without recursively drilling down into each argument of each action?
2. Have the context update itself so that myapplication myaction -? only returned the help usage for that action? (I see you've added SpecifiedAction to ArgUsageOptions, but it still isn't there in the AfterCancel of HelpHook.

If it would be possible to do this, I wouldn't need UrlHelpHook at all really!

Thanks!

Fixed in 2.5.0.0

[HelpHook] will now automatically know if there was an action specified on the command line and will only show specific help for that action in that case.
