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.

Open-source, free, multi-platform BASIC compiler, with syntax similar MS-QuickBASIC (including the GFX statements), that adds new features such as pointers, unsigned data types, inline assembly, a pre-processor and many others.

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, BASIC interpreter, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

JWasm is a Masm-compatible assembler. It supports 16-, 32- and 64-bit code, instructions up to AVX and various output formats. It's written in C.

DOS/32 Advanced DOS Extender is a drop-in replacement for the DOS/4GW DOS Extender and compatibles. Being fast, small and flexible DOS/32A can be used in many environments, from embedded systems to DOS emulators, by both developers and end users alike.

MinForth V3.4 is a classic Forth system with command-line interface. Development resource requirements are minimal. A source text editor and a C compiler are sufficient. By design no toolchain is required to adapt or rebuild MinForth. A complete rebuild takes only few seconds. Current sources are for Windows and Linux (32-bit or 64-bit). MinForth primitive definitions are written in mixed Forth and C language and are transpiled to pure C code. Main but not exclusive application for the transpiler is to build the MinForth V3.4 high-level Forth compiler. MinForth V3.4 is widely conformant to the Forth-2012 draft standard and passes the usual test suites.

Fast and efficient self-assembling 80x86 assembler for DOS/Win32/Linux; with 8086-80486/Pentium/MMX/SSE/AVX/XOP instructions support, 16-bit/32-bit/64-bit code, binary/MZ/PE/COFF/ELF output formats.

Provides, maintains, and improves the GNU development tools on Hitachi H8 series.

Compiler for high level language for Microchip PIC microcontrollers

Draak is a multi-language, macro compiler, meaning all syntax and code generation is defined in a single file. Draak is a single binary that is able to compile any context free language (like C, Pascal, Java) for any platform with only 1 file.

I'm taking various older versions of the OS/2 based EMX port of GCC and re-hosting them on Win32. This way I can use multiple core machines to build my OS/2 side projects.

ANASM is an assembler , which is written completely in assembly language.

The Bas2Lee Compiler is a BASIC langauge that is compiled to LeeOS kernel 0.0.2 binary form. It's purpose is to speed up and make simple the development of the LeeOS project and any other projects that are to be developed in the future for LeeOS.

UltraBasic is a QBasic compatible compiler, written originally by Gabriel Fernandez, and continued until 2004 by Angelo Rosina. It was hosted on Geocities, and has been moved here because of Geocities shutdown. Source code is in QB PDS 7.

A compiler which translated AspectFun program into Haskell.

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

Falconer-Try Studios is developing this new gaming engine for 2D, 3D and soon VR environments. It will be best for RTS and FPS games. See the documentation for more data.

Hispascal - Es un proyecto para traducir el Pascal a Espańol. Con Hispascal se podrá enseńar Pascal, y las bases de la programación de una manera intuitiva. Ahora incluimos un portal de programacion didactica.

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.

NovaX is a set of programs that is being devloped for small company's and beginners in the fields of HTML and programming. Coded in Python and C++, this is also a good replacement for MS Office. NOTE: This requires Python to be on your PC. ( Python.org )

An open-source cross-platform compiler for the Savage Innovations OOPic microcontroller.

Open SPHiNX C-- Compiler is a set of compiler and libraries based on the "SPHiNX C--" programming language created by Peter Cellik.

A full development kit, based on XSCompiler. Multi-platform compiler and IDE, many libraries and examples. Uses an innovative programming language, an improved version of the standard and well-known C/C++.

This is PopAsm, the popular assembler project. It is intended to support the syntaxes of the most used assemblers so existing code has no need to be rewritten. It also assembles instructions of all intel-compatible CPUs.

Aims at bringing the QuickBASIC language to the GNU platforms.
