A fast, concise, readable, pragmatic and open sourced programming language.

The Odin Programming Language

The Odin programming language is fast, concise, readable, pragmatic and open sourced. It is designed with the intent of replacing C with the following goals:

• simplicity
• high performance
• built for modern systems
• joy of programming
• metaprogramming

import "core:fmt.odin"

main :: proc() {
	program := "+ + * 😃 - /";
	accumulator := 0;

	for token in program {
		switch token {
		case '+': accumulator += 1;
		case '-': accumulator -= 1;
		case '*': accumulator *= 2;
		case '/': accumulator /= 2;
		case '😃': accumulator *= accumulator;
		case: // Ignore everything else
		}
	}

	fmt.printf("The program \"%s\" calculates the value %d\n",
	           program, accumulator);
}

Demonstrations:

• First Talk & Demo
  • Talk
  • Demo
  • Q&A
• Composition & Refactorability
• Introspection, Modules, and Record Layout
• push_allocator & Minimal Dependency Building
• when, for & procedure overloading
• Context Types, Unexported Entities, Labelled Branches
• Bit Fields, i128 & u128, Syntax Changes

Requirements to build and run

• Windows

  • x86-64
  • MSVC 2015 installed (C++11 support)
  • LLVM binaries for opt.exe and llc.exe
  • Requires MSVC's link.exe as the linker
    • run vcvarsall.bat to setup the path

• MacOS

  • x86-64
  • LLVM explicitly installed (brew install llvm)
  • XCode installed (for the linker)

• GNU/Linux

  • x86-64
  • Build tools (ld)
  • LLVM installed
  • Clang installed (temporary - this is Calling the linker for now)

Warnings

• This is still highly in development and the language's design is quite volatile.
• Syntax is not fixed.

Roadmap

Not in any particular order and not be implemented

• Compile Time Execution (CTE)
  • More metaprogramming madness
  • Compiler as a library
  • AST inspection and modification
• CTE-based build system
• Replace LLVM backend with my own custom backend
• Improve SSA design to accommodate for lowering to a "bytecode"
• SSA optimizations
• Documentation Generator for "Entities"
• Multiple Architecture support
• Debug Information
  • pdb format too
• Command Line Tooling
• Compiler Internals:
  • Big numbers library
  • Multithreading for performance increase
