Open Source Pascal Compilers for Linux

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.

Action! is a programming language for the Atari 8-bit family of microcomputers. It features an integrated editor, a debugger, and a 6502 compiler. Action! was created by Clinton Parker and released on cartridge by Optimized Systems Software (OSS) in 1983. Its syntax is similar to that of ALGOL 68.  Action! is significant for its high performance, which allows games and graphics demos to be written in a high-level language without the use of hand-written assembly language code. Action! language constructs were designed to map cleanly to 6502 opcodes. In 2015, Clinton Parker released the Action! 3.6 source code to the public under the terms of GPL. This project is intended to preserve the Action! source code, provide fixes for known bugs, and add new features in version 3.7.

Vector Pascal is a language targeted at SIMD multi-core instruction-sets such as the AVX and SSE2 or x86-64-v3. It has a SIMD compiler which supports parallel vector operations, loop unrolling, common sub expression removal etc. It is implemented in Java.

p5c is a fast portable iso standard pascal compiler. It is derived from the pascal p5 compiler and creates gnu c code instead of p-code. This makes it very fast since it uses gcc to generate native code. p5c is multi platform - it is easy to get up and running since you only need gcc to start. Using gcc enables extra tools like a static analyser and code coverage analyser. Execution profiling described in the blog here -> https://sourceforge.net/p/pascal-p5c/blog/2017/07/how-to-use-profiling-to-speed-up-p5c-pascal-programs It extends p5 by adding arbitrary set limits and conformant arrays. The project also contains p5x - pascal with extensions to the standard pascal language (underscores allowed in identifiers, otherwise in case statement, constant expressions, etc)

Here you can find both an Oberon V4 system for Linux (x86) and a collection of Oberon V4 sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server[1] and on the one of the University of Linz[2] where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list[3] is an established channel for its discussion and followed also by the administrators of this SF project.

compiler for a Pascal like language that build Flash animation (SWF) FlashPascal2 is a more advanced free compiler availabe at http://flashpascal.execute.re/

NEWS: The MPL language is now completely defined. No more language changes are to be made. The compiler is complete and should be easy to translate to other languages if you so choose. MPL is a small, simple language based on BCPL, B, C and Jesusonic. The compiler and interpreter are written in portable Pascal. I have successfully compiled MPL for CP/M, DOS, Windows, Atari ST, Amiga and the Tandy Colour Computer. MPL is designed to be tiny in every way, while implementing all the important features of BCPL & B. The result is a compiler written in a high level language (PASCAL) which compiles to under 16K (CP/M). The symbol table, language syntax, and bytecode are all optimized for size. I will write a MPL Reference Manual in time. Contact myself if you want to help get that written.

FORTH-like language compiler for AVR ATMega

AllInOneRuby creates an Windows or Linux executable that includes both the Ruby interpreter and the runtime libraries. Why? Because it's sometimes not easy, or allowed to do a complete Ruby installation. That's where AllInOneRuby comes in.

Le projet Atlantis est une collection de composants et de bibliothèques pour Lazarus. The Atlantis project is a collection of components and libraries for Lazarus.

Experimental compiler for new .NET language written in C#. Based on Pascal-like Microsoft Navision C/AL programming language. Dedicated for working with databases. It has a built-in O-R mapper. Current implementation works with Microsoft SQL Server DBMS

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.

DURIAN is a Free Delphi Web Application Server for make interactive dynamic web documents in the Pascal server-side html-embedded scripting language for Windows (Delphi) and Linux (Kylix).

A free pascal compiler targeting the Microsoft .NET and Mono platform; Full compatibility to the Borland Delphi.NET compilers is one of the main goals.

MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler

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.

PAS2PHP will translate a large subset of Object Pascal to PHP, allowing you to write web applications using Lazarus/FreePascal, and then run the application on a standard HTML/PHP server. Over the last week, a lot of work has gone into PAS2PHP. Most of the major issues are resolved. There are still a number of incompatibilities which are either not fixable, or have simple workarounds. As of v0.5, you should be able to write entire PHP applications in Pascal. The key to coding for PAS2PHP is to understand the limitations of PHP. Read the example code provided, and always check the outputed PHP code to understand how this works. As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.

Port of the Pascal-P4 compiler to Free Pascal and Delphi. The source code of Pascal-P4 is commented in the book "Pascal Implementation" by Steven Pemberton and Martin Daniels. The book is readable online at http://homepages.cwi.nl/~steven/pascal/

RUG is an universal machine-friendly binary file generator. Together with suitable macro packages, it can be used to assemble executables for almost any known processor. The main goal is to build a backend for a future Scheme translator.

RubyScript2Exe transforms your Ruby script into a standalone Windows or Linux executable. You can look at it as a "compiler", for it collects all necessary files to run your script on an other machine.

A compiler for a simplified pascal language. It runs in a x86 computer with a Linux-based OS. The purpose of this project is to show how a source code in pascal can be converted to x86 assembly.
