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.

SDCC is a retargettable, optimizing standard C (ANSI C89 / ISO C90, ISO C99, ISO C11 / C17, ISO C23) compiler that targets a growing list of architectures: STM8, MCS-51, DS390, HC08, S08, Z80, Z180, R800, Rabbit, SM83, eZ80 in Z80 mode, Z80N, TLCS-90, Padauk PDK14 and PDK15 microprocessors. There also is incomplete support for the Microchip PIC16 and PIC18 and the Padauk PDK13 and MOS 6502.

tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached. This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris. tmux depends on libevent 2.x, and on ncurses. To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed. Some platforms provide binary packages for tmux.

Babel is a toolchain that helps you write code in the latest version of JavaScript. It converts ECMAScript 2015+ code into a backwards compatible version of JavaScript that can be run by older JavaScript engines. With Babel you can transform syntax, polyfill features that are missing in your target environment, transform source code and more!

PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, AIX and Solaris. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.3, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility. The main goal of PyInstaller is to be compatible with 3rd-party packages out-of-the-box. This means that, with PyInstaller, all the required tricks to make external packages work are already integrated within PyInstaller itself so that there is no user intervention required. You'll never be required to look for tricks in wikis and apply custom modification to your files or your setup scripts. As an example, libraries like PyQt, Django or matplotlib are fully supported, without having to handle plugins or external data files manually.

This project currently provides the GNAT Studio Ada development environment, packaged for macOS. For a source of the compiler and software packages, for various operating systems, see https://ada-lang.io and Alire. For up-to-date releases of the GNAT compiler packaged for macOS, see https://github.com/simonjwright/distributing-gcc/releases. Older releases are retained for historical reasons.

The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content. 'Ready-to-build' examples explain related concepts and facilitate practical applications.

"Aubit 4GL" is a project to make GPL, OpenSource, Informix-4GL compatible compiler, and continue to extend functionality needed to write most efficient and productive business related, database oriented applications. See "Home Page" link for more.

z390 Portable Mainframe Assembler and Emulator

The goal of the Fortran-to-Java project is to provide Java Application Programming Interfaces (APIs) to numerical libraries originally written in Fortran (particularly BLAS and LAPACK). The result of this work, JLAPACK, is distributed here.

The MDK provides a simulator of D. Knuth's MIX computer, and a development environment to write, run and debug MIXAL programs on it.

nwcc is a C compiler for Unix systems targeting *BSD, OSX, Linux and Solaris on x86 (nasm/gas), FreeBSD, OSX and Linux on AMD64 (yasm/gas), Solaris on SPARC, AIX and Linux on PPC/PPC64 and IRIX on MIPS64. Cross-compilation is supported.

Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees. The user can specify parse-tree traversals for easy ordering of side effects such as code generation. Ox handles the tedious and error-prone details of writing code for parse-tree management, so its use eases problems of security and maintainability associated with that aspect of translator development.

DBOW is a database compiler-compiler or front-end. It takes table definitions in a relatively high-level language and prepares C, C++, PHP, Perl (etc) functions for manipulating the database. It will also produce SQL table data for MySQL.

The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

A Java bytecode weaver that enables you to take advantage of the new 1.5 language features in your source code, while still retaining compatibility with 1.4 virtual machines.

A library written in Objective-C for linux or others gcc-enabled systems that brings support of slots and signals ŕ-la Qt in the language, and a windowing toolkit made in OpenGL or X11. Other useful tools may also be included such as XML.

Decouple your GUI building code from the rest of your application. Using an XML description, the Java Gui Builder will build appropriate windows, controls and objects for later retrieval by the mainstream code.

lfyre is a general purpose, compiled programming language. It offers high performance, expressive power and flexibility. It has many features found in other languages, plus extra features as creating new operators, keywords and programming paradigms.

FastSim consists of: - 'Facile' a highly flexible and expressive processor-architecture specification-language. - A compiler for the specifications which produces high-performance, fast-forwarding simulators.

Compiler for java assembly to class file. This compiler contains dead code detection and allow creating method, field and constructor from a java assembly file

MultiJava adds open classes and multiple dispatch to Java. Open classes let one add new operations to existing objects. Multiple dispatch has many uses; one typical example is to write event handlers for Swing applications while avoiding nested ifs.

QJ-Pro is a sophisticated code quality assessment and coding standards technology for Java development detecting potential software defects at compile time. It offers the ability to significantly reduce code review effort by automating a major portion of
