Open Source OpenBSD 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.

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!

MLton is a whole-program optimizing compiler for Standard ML. MLton generates small executables with excellent runtime performance, utilizing untagged and unboxed native integers, reals, and words, unboxed native arrays, fast arbitrary-precision arithmetic based on GnuMP, and multiple code generation and garbage collection strategies. In addition, MLton provides a feature rich Standard ML programming environment, with full support for SML97 as given in The Definition of Standard ML (Revised), a number of useful language extensions, a complete implementation of the Standard ML Basis Library, various useful libraries, a simple and fast C foreign function interface, the ML Basis system for programming with source libraries, and tools such as a lexer generator, a parser generator, and a profiler.

cdd is the lexical, grammatical, and syntactic analyzer of the C÷÷ dialect. The latter is not a programming language, but a set of variations in the C language that cdd analyzes, converts to C code and compiles by calling to g++.

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.
