About

Whilst there are same Console class methods for setting text and background colors, there are no methods for setting text attributes such as bold, underline, etc. This library provides a simple way to do this. This library enables inline code (that is, with in a string) to change text format when writing to the console using Console.Write() and Console.WriteLine() methods.

The class entities have been made a cryptic as possible whilst maintaining interpretation upon inspection. The strings so used are not escaped, but are interpreted by the library.

String Interpolation is used to embed the format strings in the text to be written to the console.

The format strings are at 2 levels.

• Quite explicit e.g. {Fmt.fg(Fmt.Col.yellow)}
• Cryptic e.g. {F.fgYel}

Both of the code segments above will produce the same result. The cryptic version requires the using statements as in the following code to alias the class names.

## Example Console Code

```cs
using B = ConsoleTextFormat.Fmt.Bold;
using F = ConsoleTextFormat.Fmt;
namespace ConsoleApp9
{
    using System;
    using ConsoleTextFormat;

    internal class Program
    {

        static void Main(string[] args)
        {
            Fmt.Heading("Hello, World!",Fmt.Col.yellow, Fmt.Col.blue);
            Fmt.RainbowHeading("Hello, World!", Fmt.Col.yellow);
            Fmt.Info("This is a topic:", "Information");            
            Console.WriteLine($"{Fmt.bg(Fmt.Col.white)}Hello, {Fmt.b}World!{Fmt._b}{Fmt.clear}");
            Console.WriteLine($"{Fmt.fg(Fmt.Col.yellow)}Hello, {Fmt.b}World!{Fmt._b}{Fmt.clear}");
            Console.WriteLine($"{Fmt.fg(Fmt.Col.blue)}Hello, {Fmt.clear}World!");
            Console.WriteLine($"{B.fgRed}{B.bgCya}Hello, {Fmt.clear}World!");
            Console.WriteLine($"{F.fgRed}{F.bgCya}Hello, {Fmt.clear}World!");
            Fmt.Press2con();
            Fmt.Press2con("when ready."); 
       }
    }
}

• 2024-09-07: Added Fmt.Heading() and Fmt.RainbowHeading() methods to format text as headings.
• 2024-09-07: Added Fmt.Info(topic,info) method.
• 2024-09-13: Added Press2Con "Press any key to continue" method. Optional messages to pre and post pend. Also, Info() 2nd parameter IS optional.
• 2024-09-13: Added Prompt() added. As per Info() but no newline. Heading clears screen. And '_' in heading to blank.
• 2024-11-06: Added HideMenu Items to Layout. So items on end of enum list can not appear in menu.

    Layout.AddHideMenuItems("MaxType");
    Layout.AddHideMenuItems("Undefined");
    Testtype = Layout.SelectEnum<ConsoleTestType>((int)Testtype + 1, ref quit, true);
    Layout.ClearHideMenuItems();
