How to display help screen about fluent-command-line-parser

[siywilliams]

You can setup any help arguments, such as -? or --help to print all parameters which have been setup, along with their descriptions to the console by using SetupHelp(params string[]).

For example:

// sets up the parser to execute the callback when -? or --help is detected
parser.SetupHelp("?", "help")
 .Callback(text => Console.WriteLine(text));

Since v1.4.1 you can also choose to display the formatted help screen text manually, so that you can display it under other circumstances (see #29).

For example:

var parser = new FluentCommandLineParser<Args>();

parser.SetupHelp("?", "help")
 .Callback(text => Console.WriteLine(text));

// triggers the SetupHelp Callback which writes the text to the console
parser.HelpOption.ShowHelp(parser.Options);

This worked perfectly. I think it is the only thing missing from the docs.

Anyways, thank you. This project is great!

Thanks for the feedback. I'll update the docs to include the help setup.
