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
There is a Truffle AST serializer in
OzSerializerusing 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
Early stage but the Panel and Browser are working.
- Java 8
- Maven 3
- C/C++ toolchain (
build-essential) for building Graal
- Python 2.7 (for
- Ruby >= 2.2.0 (for the launcher)
mkdir mozart-dev cd mozart-dev git clone https://github.com/eregon/mozart-graal.git cd mozart-graal rake
It takes around 5 min to build everything.
Graal is not built by default to save time. To build it, run
On recent Linux, you need to do part of the build manually, see Building JVMCI.
IDE: IntelliJ IDEA
IntelliJ IDEA configuration are checked in the repository and should work out of the box.
