Types

Built-in Types

Keyword	Size	Signed?	Kind
u8	8 bit	No	Integer
i8	8 bit	Yes	Integer
u16	16 bit	No	Integer
i16	16 bit	Yes	Integer
u32	32 bit	No	Integer
i32	32 bit	Yes	Integer
f32	32 bit	Yes	Floating

Booleans

There is no boolean type defined explicitly. Any non-zero value is interpreted as true.

Pointers

Yeah there are also pointers.

Note

Pointers technically aint supported in brainfuck, but you can still pass a variable as a reference to a function anyway.

You can declare a pointer type like this:

i32* yeah;

This will declare a variable "yeah" that points to a 32 bit signed integer.

You can also declare a pointer that points to a struct like this:

struct Vector2
{
    f32 X;
    f32 Y;
}

Vector2* point;

... and you can access its fields like normally you do:

f32 x = point.X;

Note

If you try to access a field of a zero pointer, depending on the --no-nullcheck argument a runtime exception will be thrown.

You can set the value where the pointer points to like this:

*yeah = 44;

Note

I want to make a better syntax for field dereferencing, because what if the field is a pointer type and you want to set the pointer's value or the value where the pointer points to? Idk man, I will implement it when I feel like to.

Arrays

You can define array types like this:

var values = i32[6]; // This will make an array of length 6

All array types are value types, so the variable above will allocate 4 * 6 bytes on the stack. You can access each elements using the indexer:

values[0] = 564;
values[4] = 1;
i32 v = values[4];

If you define a pointer to an array, indexing it will dereferene the pointer. In other languages, you can also use the indexer on simple pointer types like this:

int *buffer;
buffer[3] = 7;

However in this language, this is not allowed since you can only index an array. You can convert the code above into BBL:

int[]* buffer;
buffer[3] = 7;

Structs

You can define a struct as follows:

struct Point
{
  i32 x;
  i32 y;
}

And use it like this:

Point point;
point.x = 37; // Set the "x" field to 37
point.y = 81;

Generics

I will explain it when I feel like to.

Aliases

You can alias any type with a name like this:

alias int i32;
alias string u16[]*;

And you can use the alias name like any other type:

int number;
string text;
