Hare is an imperative, statically typed system programming language created by Drew DeVault.[1]
The language began development in December 2019 and was initially released on April 25, 2022.[2] Hare aims to be a lightweight, type safe, and intuitive alternative to C.[3]
Goals[edit]
The goals of Hare's design are:
- To create a "conservative" successor to C, offering polish with minimal bloat.[2]
- The ability for any single programmer to fully understand the Hare toolchain.[4]
Not a C replacement[edit]
According to its creator, Hare does not intend to replace C in all its areas of application:
"Hare is not a “kitchen sink” language: Hare does not attempt to solve every problem, but it does strive to solve the problems we’re interested in well."
[...]
"Hare aims to be successful within its niche for the programmers that find its ideas compelling, and nothing further. [...] I was pretty frustrated to see the “Hare is a C replacement” mantra repeated in the media despite issuing no such claims."
– Drew DeVault, on the goals of the Hare programming language[4]
Hare gears itself towards an audience which shares its creators' philosophy of hygienic programming.
Description[edit]
Hare is intended to offer an alternative workflow for C programmers. It is designed for low-level systems programming, marketing itself as simple, stable and robust.[5][6] The language features a static, inferred type system as well as manual memory management.[4][7] Hare's innovations upon C include full UTF-8 support, a tagged union based error handling system[8] and a context-free interpreter.[7] The language emphasises broad applicability and portability.[9]
Hare runs on Linux, as well as all BSD operating systems.[10]
A lightweight language[edit]
The Hare compiler is lightweight, with the language as a whole geared towards portability, requiring only 1.4MB of storage.[5] Hare utilises the QBE compiler tool, unlike many modern programming languages which utilise LLVM.[4][11] It also aims to minimise reliance on external dependencies.[1][6]
Drawbacks[edit]
The language lacks many features present in other C alternatives the likes of Zig or Rust, such as code evaluation at compile-time.[citation needed] Hare also does not, nor does it plan to in the future, natively support functionality on proprietary operating systems such as MacOS and Microsoft Windows, though there exist third-party dependencies that provide such support.[4]
The most widely criticised aspect of Hare is its complete lack of generics, requiring developers to implement their own basic data structures, such as the hash table.[12]
Examples[edit]
Multilingual HelloWorld[edit]
This example demonstrates the high-level nature of Hare's syntax and its inferred type system.
use fmt;
export fn main() void = {
const greetings = [
"Hello, world!",
"¡Hola Mundo!",
"Γειά σου Κόσμε!",
"Привіт, світе!",
"こんにちは世界！",
];
for (let greeting .. greetings) {
fmt::println(greeting)!;
};
};
