Sabre v0.1.0

Written by Reuben Roessler@ Wed Mar 04 2026

Rename Notice

Since v0.3.1-stable Talos has been renamed to Sabre. It is recommended to use any version since the rename both to align with current documentation and for newer features and bug fixes.

If you are currently using an old Talos version, please upgrade to Sabre using the appropriate installer script:

curl -fsSL https://sabre.rroessler.io/install.sh | bash

Otherwise if you have retroactively installed a Talos version after Sabre was released, you can use the following to upgrade:

Terminal
talos upgrade

Hello, Sabre!

Welcome to the v0.1.0 release of Sabre!

Sabre is a strongly typed programming language focusing on developer experience for scalable and performant concurrent applications. It looks something like this:

// Functions can be strictly typed, and variables inferred
let multiply = fn (a: Number, b: Number): Number => a + b;

// When initializing variables, they can also be strictly typed
let future: Future[Number] = multiply::async(6, 7);

// Sabre also exposes concurrency through green-threads
Debug.println(future.await());

Why, Sabre?

In short, curiosity.

I started this project as a means of learning more about programming, which then slowly evolved over time into a more fully featured language. My goal was a language similar to TypeScript and Dart, but with more extensive tooling to power the development of a rich standard library written in the language itself.

What's New?

Realistically, this release contains the baseline implementation of Sabre and ships with an initial set of core development tools. These are in no way final, but at least a starting point for the language to improve itself from. As such, a brief overview of the new features are:

  • This is the first core release of Sabre.
  • This website which contains documentation and more.
  • Fully featured development tooling (barebones):
    • Dynamic and concurrent runtime.
    • Builtin testing/benchmarking framework.
    • Modularized project configurations for monorepos.
    • Builtin type-analysis, linting and formatting.
    • Bundler for shipping standalone executable applications.
