matebabe
matebabe is a toy JVM built in Rust targeting Java 11. As it is just
developed in order to learn, it has no certain goals besides running some small
programs that bring new challenges.
Requirements
As matebabe does not come with it's own set of .java files for the required
JVM classes, matebabe reads classfiles from a local built of OpenJDK 11.
In order to build OpenJDK, clone, and run:
bash configure --disable-warnings-as-errors
makeNote: building OpenJDK may already require a Java Installation.
This will built the whole JDK, although we are just interested in building
the classes. After building is done, you may need to adjust the class_path
variable in src/run.rs, depending on where the final build files are located
relative to the directory matebabe is executed in.
matebabe itself is build in Rust, so a recent version of Rust is also
required.
Usage
In order to run a class file, use matebabe run <classname>, eg: matebabe run Main
