jaktJ

A toy JVM class file parser written in Jakt.

Motivation

The main purpose of this project is to get a feel for using Jakt. A class file parser felt like something that is easy, and at the same time big enough so that one can get a feel for the language without getting lost in the sample problem.

Building with jakt

jakt src/main.jakt -o jaktj

Building with CMake

Make sure to install the jakt compiler somewhere. For example, /path/to/jakt-install.

This can be done by cloning jakt, and running the following commands from its directory:

jakt> cmake -GNinja -B build -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_INSTALL_PREFIX=/path/to/jakt-install
jakt> cmake --build build
jakt> cmake --install build

Next you can build this project by configuring CMake to know where to find the jakt cmake helper scripts.

> cmake -GNinja -B build -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_PREFIX_PATH=/path/to/jakt-install
> cmake --build build

Running the application

After building, the program will be in the build directory.

> ./build/jaktj samples/hello_world/Main.class

This will (more or less) pretty print the class file content to stdout.
