Expressions
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) |
a, b and c can be any numeric literal or another expression.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 accessPROVIDER OPERATORS
a can also be replaced with the $ operator to query information about the loaded dataOperator | Description |
|---|---|
addressof($) | Base address of the loaded data |
sizeof($) | Size of the loaded data |
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 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 |
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
The cast operator changes the type of an expression into another.
fn test(float x) {
return 1 + u32(x);
}
test(3.14159); // 4
