Dyalect is a dynamic programming language for .NET Core platform. It is lightweight, fast and modern. Dyalect (or Dy for short) is written in C# and has zero dependencies except for standard .NET Core libraries, which means that it can seamlessly run on Windows, MacOS and Linux. Moreover you can use the same binaries on any of these platforms! Dy runs on the top of its own high performance virtual machine. It compiles fast and can be used as an embeddable language or as a scripting language of your choice. It is also a good language to learn programming. Dyalect offers modern syntax, inspired by such languages as C#, Swift, Go and Rust, first class functions, coroutines, expressive modules, a dynamic type system with an ability to extend existing types with new functions and much more. Dy is shipped with a crossplatform interactive console. Main repo: https://github.com/vorov2/dyalect

ZLR is a Z-Machine interpreter designed to run modern interactive fiction games.

A toy programming language that supports english and italian keywords. It's goal is to be a language for algorithm prototyping, simple enough to be teached to kids.

NLT is free, open-source C# lexer and GLR parser suite -- which translates to ability to parse ambiguous grammars. Grammar can be defined directly in code or (preferably) in separate file (lex/yacc-like) for included generator. If you understand/guess the meaning of grammar in C#: // scanning lexer.AddStringRule(")", match => SymbolEnum.RPAREN); // parsing prod_builder.AddProduction(SymbolEnum.exp, SymbolEnum.LPAREN, SymbolEnum.exp, SymbolEnum.RPAREN, (_1, e, _3) => (AstNode)e); or grammar in NLT format: // scanning /[A-Za-z_][A-Za-z_0-9]*/ -> IDENTIFIER, IdentifierSymbol.Create($text); // parsing program -> list:namespace_list { new Program(currCoords(), (Namespaces)list) }; you should be able to use it :-). There is Example project included which serves as tutorial.

An hacky CHIP-8 interpreted coded in c#, with no dependencies other that the windows console. The goal was to understand how a bytecode interpreter works, not a perfect CHIP-8 emulation.

All other C# Ghostscript wrappers that you can find on the internet does not allow you to progressively render PDF page directly to the screen without exporting the page to the disk first. This wrapper does not require exporting to the disk, it can render tiles progressively from the Ghostscript interpreter. Please go to http://ghostscriptnet.codeplex.com/ for development files.

ClearLisp is a Common Lisp interpreter written in C# with a large library including all of .NET and an extensive object model. Supports IIS and XSP or Apache with mono. Includes sample code of a personal, file based wiki web application.

A toolkit for crawling information from web pages by combining different kinds of "actions". Actions are simple operations such as navigation to a specified url or extraction of text from the html. Also available is a graphic user interface.

An easy-to-use, interpreted language with a simple syntax, which is very suitable for beginners and hobbyists. The package contains a command-line interactive interpreter and a window interpreter.

NSP is the complete object-based scripting language written in just a few thousand lines of ansi c. It's portable, thread-safe, flexible, embeddable, expandable and easy to understand (as a language and as an API).

3DProS is a programming tool. It helps people create 3D animations, design custom 3D controls and solve lots of graphic problems easily, just by drag and drop. Besides a built-in language called MathScript, it also supports Free Pascal and MinGW C++

BF (Brainfuck) integrated development environment, written in C#. Features syntax highlighting, language interpretation, break points, and ability to view variable (slot) contents.

A C# interactive interpreter. The majority of the actual parsing is done by Mono's mcs, but to the user it looks like a C# interpreter. The project is currently inactive. If anybody want to continue it, please email the current maintainer.

CLearSharp is a clean C#-implementation of Common Lisp. The big goals are ANSI standard compliance, interoperability with Java and integration with scripting environments. This project is meant to be a sibling to CLearJ, with sharing of implementation.
