Odin Programming Language Index

📌 Overview & Philosophy

"A safer C for high performance, modern systems, and data-oriented programming."

Odin is a general-purpose, data-oriented language built for sane software development. It gives you explicit control over memory and context while removing standard C headache boilerplate, featuring distinct strong typing, native vendor bindings (Vulkan, Raylib, GLFW), and built-in multi-return semantics.

An example:

package main

import "core:fmt"

main :: proc() {
	fmt.printf("Hi I am written in Odin!\n")
}

📑 Core Language Reference Notes

• Variables — Declaration syntax (:=, : Type =), zero-values, and --- uninitialized buffers.
• Functions — Multiple returns, explicit procedure overloading (proc{}), #by_ptr, and implicit context.
• Types — Sized integers, b32, memory alignment (#align), tagged unions, and bit_set flags.
• Packages — Directory-based package scoping, imports, and collection namespaces (core:, vendor:).
• Precision — Exact integer overflow mechanics, f32/f64 precision limits, and float drift.
