A compiler for Jepeto programming language.
Jepeto is designed for educational purposes at ECE college, University of Tehran; it is inspired by the ML programming language, and follows a declarative coding style.
main : k(155, true, "str");
func f(a, b) : {
print([a, b, a, b, b, b][b] * -2);
return 13;
}
func g() : {
return f;
}
func h():{
return void;
}
func r():{
return ()->{print("PLC_1400");return "CLP";};
}
func k(arg1, arg2, arg3) :{
h();
g()(arg1, 2);
if (~arg2):
return arg3;
else:
print((a, b)->{print(a);print(f(20, 1));return 1;}(arg3, arg3));
r()();
return "true";

The implementation was broken into 4 phases:
- Grammar specification
- Name analysis
- Type analysis and inference
- Translation to bytecode
The compiler itself is written in the lovely environment of Java!
