Memory management

Memory management is a way to manage the memory of your program. Sacalon use manual memory management because it is used in most performance-critical applications like games,OSes, embedded systems, etc.

Sacalon uses new and delete keywords to manage memory manually.

Allocation

For allocating memory, you should use the new keyword. Note that type of the allocated memory should be pointer or reference type and passed type to new keyword should be a 

var foo : int^ = new int(1) // allocating

For easily declaring and allocating memory, use var <name> = new <type>(<args...>) statement, like this:

var foo = new int(1)

Reallocation

For reallocating memory and assigning the new value to the pointer, use <pointer> = new <type>(<args...>) statement, like this:

var foo : int^ = new int(1) // allocate memory
foo = new int(2) // reallocate memory and assign new value

Deallocation

For deallocating memory, you should use the delete keyword and pass the pointer to the memory that you want to deallocate:

delete foo

Accessing memory

Like pointer types, you can access the allocated memory value with the ^ operator:

var foo : int^ = new int(1)
print(^foo)

Critical notes

  • Don't forget to use the delete keyword at end of scope and before the end of the program..

In future, we will add a feature to show warnings when you forget to use the delete keyword.

  • You can't deallocate memory that you haven't allocated it without new keyword.

  • You can allocate, not allocated pointers:

var foo : int^?
foo = new int(1)
