New Language Features

  • or_return atom expression (suffix)
    • extremely useful for early returning with multiple return values
    • x, err = foo(); if err != nil { return } can now becomes x = foo() or_return;
  • or_else as a binary (infix) operator
  • Multi-Pointers [^]T
    • A way to describe foreign (C-like) pointers which act like arrays (pointers that map to multiple items)
    • The main purpose of this type is to aid with foreign code and act as a way to auto-document functionality and allow for easier transition to Odin code, especially converting pointers to slices.
  • Allow len and cap to return uint if a type is uint to aid people wanting to use unsigned integers
  • Unify semantics of the built-in swizzle procedure with the selector expression semantics e.g. .xyz
  • Define where #bounds_check and #no_bounds_check can be applied
    • May only be applied to one of the following statements: {}, if, when, for, switch, return, defer, assignment, variable declaration
    • May only be applied to a variable declaration, and not a constant value declaration

Packages

  • core:math/big (big integer support)
  • core:encoding/hxa (reader and writer)
  • core:c/libc - (mostly) projected all of C11's standard library to Odin, as defined by the C11 specification: N1570, or ISO/IEC 9899:2011.
  • Remove core:encoding/cel
  • The new vendor library collection
  • vendor:sdl2
    • Full bindings to the SDL2 library
    • Ships with DLLs and Libs for Microsoft Windows
    • Bundled with gamecontrollerdb.txt
  • vendor:sdl2/image
  • vendor:sdl2/mixer
  • vendor:sdl2/net
  • vendor:sdl2/ttf
  • vendor:OpenGL
  • vendor:vulkan
  • vendor:glfw
  • vendor:portmidi

Compiler Improvements

  • Unify multithreading logic through the compiler
  • Remove numerous possible race conditions
  • Disallow using on enum declarations in favour of implicit selector expressions: .A
  • Simplify data structures within the compiler for better memory reuse
  • Correct DllMain behaviour
  • Delete a lot of dead code

General Changes

  • Prefer ..= over .. in the core library
  • Add Allocator_Error.Mode_Not_Implemented
  • Allow + in import paths
  • Add #any_int directive to replace auto_cast uses on parameters
  • Add map_insert which returns the pointer to the inserted value (assuming no resizes happen in the mean time)
