Language Implementations

This page is intended to keep track of the growing number of language implementations and experiments on top of Truffle. The following language implementations exist already:

• FastR, an implementation of GNU R. *
• Graal.js, an ECMAScript 2020 compliant JavaScript implementation. *
• Graal.Python, an early-stage implementation of Python. *
• grCUDA, a polyglot CUDA integration.
• SimpleLanguage, a toy language implementation to demonstrate Truffle features.
• SOMns, a Newspeak implementation for Concurrency Research.
• Sulong, an LLVM bitcode interpreter. *
• TRegex, a generic regular expression engine (internal, for use by other languages only). *
• TruffleRuby, an implementation of Ruby. *
• TruffleSOM, a SOM Smalltalk implementation.
• TruffleSqueak, a Squeak/Smalltalk VM implementation and polyglot programming environment.
• Yona, the reference implementation of a minimalistic, strongly and dynamically-typed, parallel and non-blocking, polyglot, strict, functional programming language.
• Enso, an open source, visual language for data science that lets you design, prototype and develop any application by connecting visual elements together.

* Shipped as part of GraalVM.
