Fae is an unsafe systems programming language with a focus on utility, comfort, and tooling. It steals with flattery from such languages as Rust, Zig, Odin, and Swift. Read the language reference for a detailed snapshot of the current status of the Fae language.
- Comfortably Useful: Language features are chosen in an attempt to maximize the ratio of utility to language complexity while remaining pleasant to write and reason about
- Unsafe: Fae is an unsafe language and allows for deep developer control over memory at the cost of compile time safety guarantees
- High Quality Tooling: A language is only half the experience; having fast, accurate, and pleasant tooling is crucial
>>> cat main.fae
import fae.collections.list.List

list.push("There!")
for item, _, is_last in list.items {
print(item)
if is_last.! => print(", ")

>>> fae run --quiet
Hello, There!
>>> cat main.fae

println("Hello world")
println(f"Welcome to {language()}!")

Hello world
Welcome to Fae!

The Fae compiler and standard library are very incomplete, missing features include traits, allocator system, error system, unions, and much more.

Join the Fae project Discord server to participate in discussion and ask questions. While not ideal, Discord was chosen to maximize approachability and accessiblity.
The Fae compiler is immature and incomplete but it can be installed and experimented with today. Here there be dragons, please open an issue when you encounter bugs!
- Linux x64: Current primary supported platform, binaries available on the releases page.
Statically linked compiler, should run on any recent Linux system
By default expects GNUldto be in the path - macOS AArch64: Secondary supported platform, binaries available on the releases page.
Tested on macOS 12-14 (may work on 11)
By default expects platform shippedldto be in the path - Windows x64: Untested and unsupported as of yet. Extremely high priority to support in the near future.
These are the core set of intended supported platforms. Supporting each of these operating systems on the opposite architectures is a goal but lower priority at present.
Primitive syntax support for VSCode is available with this extension, though it lacks code formatting and language server support as those components remain to be built.
See the Build Instructions for directions on how to get up and running with a development build of the Fae language toolchain.
