Open Source OCaml (Objective Caml) Compilers

MTASC is an open-source (GPLv2) ActionScript 2.0 compiler developed by Motion-Twin Technologies (http://www.mtasc.org/). Motion-Twin no longer releases updates to MTASC though. This project is a community fork of MTASC with new improvements.

OCaml is a general-purpose, industrial-strength programming language with an emphasis on expressiveness and safety. OCaml’s powerful type system means more bugs are caught at compile-time, and large, complex codebases are easier to maintain. This makes it a good language for running critical code. At the same time, sophisticated inference makes the type system unobtrusive, creating a smooth developer experience. OCaml has two compilers. One is a bytecode compiler that generates small, portable executables and is very fast. The other is a native code compiler that produces more efficient machine code; its performance matches the highest standards of modern compilers. OCaml has great support for the most popular editors. VS Code is recommended for beginners, and for power users there is deep integration with Vim and Emacs. OCaml has a rich and dynamic community and best-in-class tooling.

The compiler for ReScript: a statically typed functional language focused on shipping. ReScript is a robustly typed language that compiles to efficient and human-readable JavaScript. It comes with a lightning-fast compiler toolchain that scales to any codebase size. ReScript cares about a consistent and fast feedback loop for any codebase size. Refactor code, pull complex changes or switch to feature branches as you please. No sluggish CI builds stale caches, wrong type hints, or memory-hungry language servers that slow you down. Every ReScript app is fully typed and provides reliable type information for any given value in your program. We prioritize simpler types over complex types for the sake of clarity and easy debugability. No `any`, no magic types, no surprise `undefined`. Use any library from JavaScript, export ReScript libraries to JavaScript, and automatically generate TypeScript types. It's like you've never left the good parts of JavaScript at all.

A modest extension to C, XMTC allows representing parallel (PRAM) algorithms as parallel programs, and run XMTC code using a compiler and cycle accurate simulator of the University of Maryland explicit multi-threaded (XMT) many-core architecture.

Jekyll is a high level programming language that can be translated to and from readable, editable C, thus allowing it to be used in C projects.

PacLang is a language for programming Network Processors. It aims to make it easy to write high performance networking applications that are portable across a range of target platforms.

*** Moved to http://github.com/esumii/min-caml *** MinCaml: An educational compiler from a tiny ML subset to the SPARC or PowerPC assembly language; Only 2000 lines of Objective Caml, but almost as efficient as---or even more efficient than---OCaml and GCC!

Newspeak is a simplified programming language, well-suited for the purpose of static analysis. The compiler c2newspeak tranforms C programs into Newspeak. Other utilities to manipulate Newspeak programs are also available.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

A small programming language provided with an OCaML compiler.

PCL-Compiler is a compiler for PCL: a simple Pascal-derived programming language, used for teaching compiler technology in the National Technical University of Athens.

This project contains a library for writing compilers/type systems and toy compilers for small games.

MUgen is an emulator generator which works in a way similar to yacc. It takes an input machine description and outputs a source file which is a fully implemented emulator of that system. This is the open-source system.
