ConsoleZ 0.1.0

ConsoleZ

A modern console rendering library

Why use this library? What use cases?

• Want a common interface/experiance across console and web apps?
• Want a richer output (colours, progress graphs)?
• Want to make a retro-console game like Tetris, Snake?
• Want Markdown in the console?

What this library does NOT do:

• Console Argument parsing
• Midnight-Commander like console forms

Key Features (done vs. in-progress):

• Zero-dependancy
• Windows 10 Console: ANSI Escape Codes
• Alternative human readble inline colour formatting "^red;Error:^; Message"
• Fast full-screen updates. Allows Retro Console games. https://onelonecoder.com/olcconsolegameengine/
• Unified IConsole working with HTML, WinForms, Console
• UI Components : Percentage Complete Graph, etc
• ASCII large fonts
• Markdown formatting

Key C# interface

What will I be programming against?

public interface ITextWriter
{
    int WriteLine(string s);        // We don't use Write, rather update the whole line
    int WriteFormatted(FormattableString formatted);
}

public interface IConsole : ITextWriter
{
    string Handle { get; }
    int Version { get;  }

    int Width { get; }
    int Height { get; }
    int DisplayStart { get;  }
    int DisplayEnd { get; }

    void UpdateLine(int line, string txt);
    void UpdateFormatted(int line, FormattableString formatted);
}

The Idea?

In my current project we have lots of command logic that output calculation reports to the console. As the functionaliy matures, or reaches a larger audience, the it gets ported to the web.

Would it not be great if the console and html versions share the same interface and rendering abilities:

• Console Renders Markdown with ASCII-art and Console standard colours (Find closest Color -< ConsoleColour)
• Html Renders to a virtual console (thread-safe) and renders HTML Markdown

Features:

• Markdown is the common format (Rendering to Console or HTML)
• ANSI escaping (+ HTML mapping)
• Threadsafe for the web (many IVirtualConsoles at once)
• Easy inline colours "Hello ^red;World^;" <-> string.Format("Hello {0}World{1}", Color.Red, Color.Default)
• Updating progress bars [###... 50%]
• Standard ASP.NET core console terminal
• Very Fast console update/FPS see: https://github.com/OneLoneCoder/videos/blob/master/olcConsoleGameEngine.h

Stretch:

• Wolfram-style cell input/output consoles
• SignalR polling to update console (vs polling ever sec)
