Outputting help text as individual lines

[tig]

Beyond parsing the string into lines, how would I modify this to call Log.Information() for each line of help generated? It seems the API is capable of this, but I'm obviously struggling to figure it out myself.

        static void DisplayHelp<T>(ParserResult<T> result, IEnumerable<Error> errs) {
            var helpText = HelpText.AutoBuild(result, h => {
                h.AutoHelp = true;
                h.AutoVersion = true;
                return HelpText.DefaultParsingErrorsHandler(result, h);
            }, e => e);
            Log.Information(helpText);
        }

There is a new overload method in v2.7

public static HelpText AutoBuild<T>(ParserResult<T> parserResult, Func<HelpText, HelpText> onError, int maxDisplayWidth = DefaultMaximumLength)

your method can be simplified as:

//DefaultParsingErrorsHandler is internally called by the method,  , autoHelp=true by default
    static void DisplayHelp<T>(ParserResult<T> result, IEnumerable<Error> errs) {
            var helpText = HelpText.AutoBuild(result, h => h);    //no parameter e=>e 
            Log.Information(helpText);
        }

Also, you can customize help and remove empty lines

var helpText = HelpText.AutoBuild(result, h =>
		{
			h.AdditionalNewLineAfterOption = false; //remove the extra newline between options
			h.Heading = "MyVerbApp 2.0.0-beta"; //change header
			h.Copyright = "Copyright (c) 2019 Global.com"; //change copyrigt text
			return h;
		}

Thanks for the tip on the new method and simplifying my implementation.

However, I don't think your response answered the core of my question: Can I get HelpText to feed me the helptext lines individually, so I can output them each individually vs. one big string?

Do you mean splitting helpText to multi lines?
You can divide the help text to multi-lines:
by splitting based on EOL \r\n as help.text.Split(...)

That's right. Yes, I know I could easily use Split, but it looked to me like the API does support just feeding me the lines separately, but I can't figure it out myself (I'm pretty rusty) and was hoping to learn something by asking.

The test project uses Split in an internal method ToLines to split helpText for test purpose.
It's not public API.
You can add this extension methods to your project.
