# Mozart-Graal
[](https://travis-ci.org/eregon/mozart-graal)
An implementation of the [Oz programming language](https://en.wikipedia.org/wiki/Oz_(programming_language)) on top of Truffle and Graal.
The bootcompiler and Oz libraries are imported from [Mozart 2](https://github.com/mozart/mozart2).
## Interesting Points
* A [master thesis](https://dial.uclouvain.be/memoire/ucl/en/object/thesis%3A10657/datastream/PDF_01/view) 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](https://github.com/EsotericSoftware/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`.
## Current Status
Early stage but the Panel and Browser are working.
## Dependencies
* Java 8
* Maven 3
* C/C++ toolchain (`build-essential`) for building Graal
* Python 2.7 (for `mx`)
* Ruby >= 2.2.0 (for the launcher)
## Build instructions
```bash
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.
Run with
```bash
./oz
```
## Graal
Graal is not built by default to save time.
To build it, run
```bash
rake build:graal
```
On recent Linux, you need to do part of the build manually, see [Building JVMCI](vm/jvmci/README.md).
## IDE: IntelliJ IDEA
IntelliJ IDEA configuration are checked in the repository and should work out of the box.
Import `mozart-dev` as a project.
