Compiler for Deca (java-ish)

This project is a compiler for the deca language written in C++.

Prerequisites

This compiler generates java bytecode in string format. You will therefore need a compiler from java bytecode in string format to actual java bytecode.

This compiler can be found at : http://jasmin.sourceforge.net/

Here is an example :

java -jar jasmin-2.4/jasmin.jar file_containing_bytecode_in_string_format.j

This will produce a java .class file which you should be able to execute using your standard JVM.

Installing

Clone the repository

git clone https://github.com/pougetat/decacompiler.git

Build the project

mkdir build
cd build
cmake ..
cd src
make

Compile a deca program (The executable is in build/src/)

./main sample.deca

Sample .deca program :

{
    int a = 3;
    if (a - 1 == 2)
    {
        while (a <= 15)
        {
            print("this is a", a);
            a = a + 1;
        }
        print("yes");
    }
    else {
        print("no");
    }
    print(a);
}

Sample deca program with classes :

class A {
    B b = new B();
}

class B {
    int b = 13;
    C c = new C();
}

class C {
    int c = 46;
}

{
    A a = new A();
    print(a.b.c.c);
}

Sample deca program with classes and methods :

class A {

    B b = new B();

    void hello()
    {
        print(b.b);
        print("hello");
    }
}

class B {
    int b;
}

{
    A a = new A();
    a.hello();
}
