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 creating an alternative to C with the following goals:

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

package main

import "core:fmt"

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);
}

Setup

Odin only supports x86-64/amd64 at the moment (64-bit), relies on LLVM for code generation and an external linker.

In addition, the following platform-specific steps are necessary:

• Windows

  • Have Visual Studio installed (MSVC 2010 or later, for the linker)
  • Have a copy of opt.exe and llc.exe in Odin/bin. Pre-built Windows binaries can be found here and must be explicitly copied
  • Open a valid command prompt:
    • Basic: run the x64 Native Tools Command Prompt for VS2017 shortcut bundled with VS 2017, or
    • Advanced: run vcvarsall.bat x64 from a blank cmd session

• MacOS

  • Have LLVM explicitly installed (brew install llvm)
  • Have XCode installed (version X.X or later, for linking)
  • Make sure the LLVM binaries and the linker are added to your $PATH environmental variable

• GNU/Linux

  • Have LLVM installed (opt/llc)
  • Have Clang installed (version X.X or later, for linking)
  • Make sure the LLVM binaries and the linker are added to your $PATH environmental variable

Then build the compiler by calling build.bat (Windows) or make (Linux/MacOS). This will automatically run the demo program if successful.

Notes for Linux:: The compiler currently relies on the core and shared library collection being relative to the compiler executable. Installing the compiler in the usual sense (to /usr/local/bin or similar) is therefore not as straight forward as you need to make sure the mentioned libraries are available. As a result, it is recommended to simply explicitly invoke the compiler with /path/to/odin in your preferred build system, or add /path/to/odin to $PATH.

Please read the Getting Started Guide for more information.

Requirements to build and run

Please read the Getting Started Guide.

• Windows

  • x86-64/amd64
  • MSVC 2010 installed (C++11 support)
  • LLVM binaries for opt.exe, llc.exe, and lld-link.exe
  • Requires MSVC's link.exe as the linker
    • run vcvarsall.bat to setup the path

• MacOS

  • x86-64/amd64
  • LLVM explicitly installed (brew install llvm)
  • XCode installed (for the linker)

• GNU/Linux

  • x86-64/amd64
  • Build tools (ld)
  • LLVM installed
  • Clang installed (temporary - this is Calling the linker for now)

• FreeBSD

  • x86-64/amd64
  • Build tools (ld)
  • LLVM installed
  • Clang installed (temporary - this is Calling the linker for now)

Other platforms may be supported but are experimental for the time being.
