An implementation of Oz on top of Truffle and Graal
An implementation of the Oz programming language on top of Truffle and Graal.
The bootcompiler and Oz libraries are imported from Mozart 2.
A master thesis was made with this project to optimize performance. It details many static and dynamic optimizations.
Tail calls are optimized and compiled as loops, see TailCallCatcherNode
.
Self-recursion is optimized further in SelfTailCallCatcherNode
.
There is a Truffle AST serializer in OzSerializer
using Kryo able to serialize Oz code.
The project uses the Coroutine patch for HotSpot to be able to create many lightweight threads.
The parser, typer, and some optimizations are written in Scala (bootcompiler/
)
and the AST produced by Scala is then translated to a Truffle AST in Translator
.
Early stage but the Panel and Browser are working.

It takes around 5 min to build everything.
Run with
./oz
Graal is not built by default to save time. To build it, run
rake build:graal
On recent Linux, you need to do part of the build manually, see Building JVMCI.
IntelliJ IDEA configuration are checked in the repository and should work out of the box.
