Jawa jest obiektowy język programowania. The Jawa programming language compiler was inspired by the meme above (author unknown).

The compiler is incomplete and it contains a few ad-hoc solutions. However, WitajŚwiecie (HelloWorld) program can be compiled as well as the necessary standard library.

publiczna klasa WitajŚwiecie {
    
    publiczny statyczny void głowny(Łańcuch[] args) {
        System.wyjście.wydrukovać("Witaj świecie");
    }
    
}

$ mkdir build
$ cd build
$ cmake -DBISON_ROOT=<bison_install_dir> -DFLEX_ROOT=<flex_install_dir> ..

Jawa compiler:

$ make jawac

Jawa standard library:

$ make jawa_stdbib

jasm is a low-level library for JVM byte code manipulation.

jawa is a Jawa compiler implemented using jasm.

stdbib contains sources of the Jawa standard library (standardowa biblioteka).

editor contains plugins for supported code editors.

$ build/jawa/jawac --ścieżkaklasy .:stdbib test/WitajŚwiecie.jawa

Make sure you have compiled the standard library.

You need to specify the standard library path and classpath:

$ java -Djava.library.path=build/stdbib -classpath stdbib:. WitajŚwiecie
