Open Source OCaml (Objective Caml) Compilers

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.

CIL (C Intermediate Language) compiles C programs into a simplified subset of C and assists with program analysis and transformation.

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.

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.

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.

Creen is a reengineering and static analysis tool for ANSI C code. Program structure analysis, slicing and refactoring.

Here we have fun developing software related to embedded extension languages and small languages in many application domains, using existing languages and/or creating new ones.

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.

A collection of tools for formalizing programming languages and compilers, based around the Coq proof assistant

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.

This is a port of the Dis virtual machine system to POSIX-compatible operating systems, based on the original Inferno sources, including a Limbo compiler. The port is intended to make the virtual machine and runtime environment more general and easily ex

*** 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!

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.

banshee-- A toolkit for building constraint-based program analyses

Felix programming language specifications and translator

Htl translator to XTA (Uppaal).

loon is a GLR parser generator that takes EBNF grammars as specifications. Tokens are specified in the grammar file, and it generates a parse tree instead of executing actions. A single grammar can output a parser in any supported language.

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.

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.

This should be the fastest way to use OCAML / OPAM on windows. It's a cygwin environment with already installed ocaml, opam, dune (opam), etc. Just unpack and execute "start.exe"
