Nova is a programming language with a high level of abstraction. This repository contains a compiler in C# (.NET) and a virtual machine in C++ (iso 17)
- Compiled (into bytecode, no JIT for now)
- Structured
- Imperative
- Functional
- Strong typing
using <nova> // Nova std library// This code is written in Nova !class MyClass{ public int Main() { Human human = -> Human("Freddy",18) human.PrintAge() Vector myVect = [7,8,9,10] myVect.Add(5) myVect.Print() // Print '7,8,9,10,5' }}struct Human{ public string Name public int Age -> Human(string name,int age) // Human constructor { Name = name Age = age } public void PrintAge() { Nova.PrintLine(Name + " is " + Age + " years old") }}- Once your nova file(s) source code is written. Just give it to the C# compiler.
- The compiler will generate a .nov file (sources to bytecode)
- Give the .nov to the C++ virtual machine and it will run your program from Main() function.
- git clonehttps://github.com/Skinz3/Nova.git
- Build Nova.Compiler & Nova.VM
./Nova.Compiler mySourceFile.nv output.nov---> myScript.nv must have a main point entry../Nova.VM output.nov----> execute the program
| OpCode | Result |
|---|---|

div | Divide two numbers on top of the stack |
dup | Duplicate element on top of the stack, and put it on tos |
jump | Define instruction pointer value |
jumpIfFalse | Define instruction pointer if condition is false on tos |
load | Load local value |
loadGlobal | Load static element on top of the stack |
call | Call a method / function |
mul | Multiply two numbers on top of the stack |
nat | Call a native method(Network, IO, kernel, all system calls in general) |
pushConst | Push constant value on top of the stack |
pushInt | Push integer on top of the stack (unused) |
pushNull | Push a Null value (nova semantics) on the top of the stack |
return | Set instruction ptr = instructions.length |
store | Store a local value |
