# Odin Language Features
|
|
|
|
* variables
|
|
* constants (compile-time)
|
|
* procedures
|
|
- overloading
|
|
- polymorphic (poly prockets)
|
|
- multiple return values
|
|
- Optional forced checking
|
|
- inline and outline actually meant it!
|
|
- local scoped procedures
|
|
* Maybe closures & lambdas?
|
|
- named parameters
|
|
- optional parameters
|
|
* struct
|
|
* enum
|
|
* raw union
|
|
* tagged union or variants or both?
|
|
* pointers
|
|
* pointer arithmetic
|
|
* defer statement
|
|
* death to headers
|
|
- no pre-declaration
|
|
* maybe both inline assembly and intrinsics
|
|
* `using`
|
|
* metaprogramming
|
|
- Compile execution
|
|
- Introspection
|
|
- Any type
|
|
* type_of?
|
|
|
|
|
|
## Basic Types
|
|
bool - true|false
|
|
- register size or variable size?
|
|
|
|
u8 - Unsigned integer
|
|
u16
|
|
u32
|
|
u64
|
|
uint - Register size unsigned integer
|
|
uintptr - integer big enough to store a pointer
|
|
|
|
i8 - Signed integer
|
|
i16
|
|
i32
|
|
i64
|
|
int - Register size signed integer
|
|
intptr - integer big enough to store a pointer
|
|
|
|
|
|
f32 - Floating Point 32 bit
|
|
f64 - Floating Point 64 bit
|
|
|
|
byte - alias for u8
|
|
rune - alias for i32
|
|
|
|
string - Immutable: once created, it is impossible to change the contents of a string
|
|
arrays - ArrayType = [count]ElementType
|
|
count = Expression
|
|
ElementType = Type
|
|
Allow for dynamic arrays? Allow use slices?
|
|
pointers - PointerType = *BaseType
|
|
BaseType = Type
|
|
|
|
struct
|
|
enum
|
|
raw_union
|
|
tagged_union
|
|
procedure
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## Basic program
|
|
|
|
import "io"
|
|
|
|
type Vec2: struct {
|
|
x, y: f32;
|
|
}
|
|
|
|
test_proc :: (x, y: f32) -> f32 {
|
|
result := x * y;
|
|
result += 2;
|
|
result /= x;
|
|
return result;
|
|
}
|
|
|
|
main :: () {
|
|
x : i32 = 123;
|
|
y := 1337; // Type inference (will be `int`)
|
|
z :: x + y; // Defined and made constant
|
|
|
|
io.print("Hellope, World! z = {}", z);
|
|
}
|
|
