Jule Manual

Appearance

Using Reference Counting ​

Include reference counting header:

cpp
#include "api/ref.hpp"

Creating References ​

Nil References ​

Recommended way:

cpp
jule::Ptr<int> my_int = nullptr;

Using default constructor:

cpp
jule::Ptr<int> my_int;

Initialized References ​

Recommended way:

cpp
jule::Ptr<int> my_int = jule::new_ptr<int>(900);
std::cout << *my_int << std::endl;

Create reference for custom allocation:

cpp
int *my_alloc = new int;
*my_alloc = 200;
jule::Ptr<int> my_int = jule::Ptr<int>::make(my_alloc);
std::cout << *my_int << std::endl;

Accessing Data ​

Change data via assignment:

cpp
jule::Ptr<int> my_int = jule::new_ptr<int>(900);
std::cout << *my_int << std::endl;
*my_int += 1000; // my_int's data is now 1900
std::cout << *my_int << std::endl;

Get or set fields via -> operator:

cpp
struct Person {
    jule::Str name;
    jule::Str surname;
};

jule::Ptr<Person> p = jule::new_ptr<Person>(Person{
    .name="Anonymous",
    .surname="Julenour",
});
std::cout << p->name << " " << p->surname << std::endl;
p->name = "Unknown"; // Set name field to "Unkown"
std::cout << p->name << " " << p->surname << std::endl;
