Open Source Compilers

A 32/64/16-bit Pascal compiler for Win32/64/CE, Linux, Mac OS X/iOS, Android, FreeBSD, OS/2, Game Boy Advance, Nintendo NDS and DOS; semantically compatible with Delphi, Borland Pascal and Mac Pascal (partially) with extra features, e.g. operator overloading.

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

epocemx is a collection of tools (including a port of GCC) and libraries which enable building EPOC R5 applications under Unix.

ELFIO is a header-only C++ library intended for reading and generating files in the ELF binary format

The Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are imperative, procedural, object-oriented, declarative using nested structures, functional, meta programming and natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, Microcontrollers, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be simple, small and flexible. Ring is distributed as a Free-Open Source project under the MIT License.

WebDGap allows you to convert any website or HTML/CSS/JavaScript web application to a native Windows, Mac, Linux, and Chrome application. WebDGap also gives you the option to export as a Chrome popup extension, and you can export your app or website as a native PhoneGap application making your app available for mobile devices :)

A programming language AL-IV (ALFOUR) is a high-level imperative object oriented programming language with minimal introduction level, easy porting to any platform claiming a very high level of safety and stability, with a controllable level of code protection, high efficiency of an executable code, full independence from a target platform, minimal enter level.

MANOOL is a practical, homoiconic, dynamic, multiparadigm general-purpose programming language with a functional core. It has high expressive power but is implemented in less than 10K LOC of optimized, idiomatic C++11 for native run-time environments. MANOOL is meant to compare and compete directly with Python, PHP, Ruby, Perl, and Tcl, although incidentally it has some combination of unusual features. Example: {{extern "manool.org.18/std/0.2/all"} in WriteLine[Out; "Hello, world!"]} Explicitly stated design priorities of MANOOL: 1. implementation simplicity; 2. expressive power, usability, and general utility, attention to syntax and semantics details; 3. correctness, security, and overall quality of implementation, run-time reliability; 4. run-time performance and scalability; 5. consistency, completeness, orthogonality of features, and language elegance, conceptual economy and purity. MANOOL strives to satisfy all of the above goals, better than existing alternatives!

C-Lesh is a game programming language for 2D games - mainly arcade and platform games. When combined with the Super Mario World (SMW) engine you can create awesome 2D platform games like Super Mario World. This language evolved from a "clone" of TI-BASIC which I began developing when I was having memory (segmentation fault) bugs with C. C-Lesh lacks memory allocation and destruction. There is no need to use pointers and you can never get memory leaks or program crashes caused by memory leaks. As C-Lesh is somewhat primitive you may like it if you are into C. I'd say its a step up from C for 2D games. Everything is set - all you need is a sprite sheet and some programming knowledge.

Forth compiler for the Compiled Virtual Machine

Small and lightweight .NET 2.0 library written in C# for quickly evaluating arithmetical expressions using interpretation or runtime MSIL generation.

Jaune is a compiler and set of libraries that can be used to write programs in the Java language for small devices. Includes a basic set of class libraries, garbage collector, and set of examples that can be run on the Nintendo GameBoy

LucidEngine is a simple layer over MIDP compatible phones that will let you write simple and old fashioned games using a specific language. Every game you'll develop will basically work on all the devices (even not phones) LucidEngine as been ported.

The purpose of this project is to modify SmartEiffel to allow it to be used to create applications for mobile device platforms such as Symbian, BREW, and J2ME. Currently the codebase is based on SmartEiffel 1.0, but we are looking into moving over to Sma

NATIVE is a project aimed at producing a version of the C# language compiler which omits native-code for various OS platforms. NATIVE does not target the CLI or use the CLR.

OS based on Agent based Security with a new type of split kernel and agents platform.

embeddable scripting language

Smalltalk environment (compiler, virtual machine, library)

otob aims to be an open-source automatic tools for building a linux or other opensource OS system for various architecture,including x86,ARM,and other architecture.The project is now under the initiall developing state,expecting your advocate.
