Operators

Operator
Description
a + b
Addition
a - b
Subtraction
a * b
Multiplication
a / b
Division
a % b
Modulus
a >> b
Bitshift right
a << b
Bitshift left
~a
Bitwise NOT
a & b
Bitwise AND
a | b
Bitwise OR
a ^ b
Bitwise XOR
a == b
Equality comparison
a != b
Inequality comparison
a > b
Greater-than comparison
a < b
Less-than comparison
a >= b
Greater-than-or-equals comparison
a <= b
Less-than-or-equals comparison
!a
Boolean NOT
a && b
Boolean AND
a || b
Boolean OR
a ^^ b
Boolean XOR
a ? b : c
Ternary
(a)
Parenthesis
function(a)
Function call
a, b and c can be any numeric literal or another expression.

Type Operators

Type Operators are operators that work on types. They can only be used on a variable, not on a mathematical expression.
Operator
Description
addressof(a)
Address of variable
sizeof(a)
Size of variable
a can be a variable, either by naming it directly or finding it through member access
PROVIDER OPERATORS
a can also be replaced with the $ operator to query information about the loaded data
Operator
Description
addressof($)
Base address of the loaded data
sizeof($)
Size of the loaded data

String Operators

String operators are any operators acting on strings directly.
Operator
Description
a + b
String concatination
str * number
String repetition
a == b
Lexical equality
a != b
Lexical inequality
a > b
Lexical greater-than
a >= b
Lexical greater-than-or-equals
a < b
Lexical less-than
a <= b
Lexical less than-or-equals

Member Access

Member access is the act of accessing members inside a struct, union or bitfield or referencing the index of an array to access its value.
Below the simplest operations are shown, however they may be concatinated and extended indefinitely as suitable.
Operation
Access type
structVar.var
Accessing a variable inside a struct, union or bitfield
arrayVar[x]
Accessing a variable inside an array
parent.var
Accessing a variable inside the parent struct or union of the current struct or union
this
Refering to the current pattern. Can only be used inside of a struct or union

$ Dollar Operator

The Dollar Operator is a special operator which expands to the current offset within the current pattern.
#pragma base_address 0x00
std::print($); // 0
u32 x @ 0x00;
std::print($); // 4
It’s also possible to assign a value to the dollar operator to change the current cursor position.
$ += 0x100;
The dollar operator can also be used to access single bytes of the main data.
std::print($[0]); // Prints the value of the byte at address 0x00

Casting Operator

The cast operator changes the type of an expression into another.
fn test(float x) {
return 1 + u32(x);
}
test(3.14159); // 4
