Open Source 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.

A new system programming language designed to occupy the same niche C is currently holding, that allows for easier development of large platform-independent systems. The aims are to: * Keep all of C's system programming strengths. * Be as efficient as C (at run-time) and as high-level as possible for the programmer. * Promote modularity and ease the development of large-scale component-based software. * Enable programming-by-contract and other high-level features (as long as they incur no extraordinary costs at run-time). * Provide a stricter and more platform-independent type system than C. * Allow direct use of existing C and platform (e.g. Win32 API) libraries. This phrase from the "SPL Language Reference" says it all: "One could say SPL is what C should have been, were it not for the limitations of the time when C was designed".

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.
