Odin v0.6.0

Additions and Changes

• Restore original declaration syntax
• Parametric Polymorphism ("Generics")
  • Procedures
    • new :: proc(T: type) -> ^T {...}
    • new_clone :: proc(v: $T) -> ^T {...}
    • copy :: proc(dst, src: $T/[]$E) -> int {...}
  • Structures
    • Vector :: struct(N: int, T: type) { e: [N]T; };
  • Type specialization
    • make :: proc(T: type/[]$E) -> T {...}
    • add :: proc(a, b: $T/Vector) -> T {...}
    • sub :: proc(a, b: $T/Vector) -> T {...}
    • foo :: proc(b: ^Bar($T, $E)) {...}
    • exists :: proc(m: map[$K]$V, key: K) -> bool {...}
• union
  • union{int, f32, FooBar, string, map[int]string}
  • Duality between any and union now. Same usage with syntax.
• raw_union is now a tag on struct
  • struct #raw_union {...}
• struct fields use semicolons
  • struct {x: f32; y: int; z: string}
• Nested Struct Declarations

struct {
	// constants
	FOO   :: 123;
	MyInt :: int;

	// fields
	x: int;
}

• Default Struct Values

struct {
	s: string = "Hellope";
	i := 123;
	b: bool; // zero value	
}

• do for inline statements rather than block
  • if cond do foo();
• Removed ++, --
  • Use += and -= instead
• Removed atomic
• Type operator precendence change
  • ^T(x) == ^(T(x))
• Additional casting syntax
  • cast(T)x
  • (T)(x)
• Uninitialized value ---
• Removal of *_val_of
  • Replaced with size_of, align_of, offset_of, type_of, type_info_of
• Compiler options:
  • -opt=0,1,2,3
  • -show-timings
  • -thread-count=4
• Multi-threaded Parser
