Papete is the name of my compiler. Written in python using ANTLR4. A project that started as a Compilers course assignment and turned out to be really fun.
The name Papete doesn't really have a meaning aside for inside jokes, but since this is computer science we're talking about, let it be an acronym:
- P.ython3'n
- A.ntlr4
- P.owered
- E.nvironment
- T.ranslation
- E.ngine

You're going to need python3, the only other dependency needed is antlr4. You can install antlr4 using the following command
pip install antlr4-python3-runtime
on linux you might want to:
pip3 install antlr4-python3-runtime
Make sure to check their page at pypi.com for further instructions.
Once you have python3 and antlr4. Git clone this project and open a terminal. You can use the following command to execute a fibonacci code sample.
python -m App.main SampleCode/fib.ppte
on linux you might want to:
python3 -m App.main SampleCode/fib.ppte
! Inner function example;
! Function assignment example;
! Function passed as return example;
func foo(){
func bar(){
print("Hello World!");
};
return bar;
};
func globalScopeBar = foo();
globalScopeBar();
! [outputs]: Hello World!! Function as argument example;
! If and else stament example;
func getOne(int a, int b, func selector){
bool pickVarA = selector(a, b);
if(pickVarA){
return a;
}else{
return b;
};
};
! Selector function will be used to determine which
! value to pick;
func selector(int a, int b){
return a > b;
};
print("Picking between numbers using custom selector: picked = " + getOne(10, 20, selector));
! [outputs]: Picking between numbers using custom selector: picked = 20More samples can be found on the CodeSamples folder.
