Eve logo

Eve is a programming language based on years of research into building a human-first programming platform.

This repository hosts a preview of Eve v0.3 alpha, which is no longer under active development.

Getting Started with Eve v0.3 preview

Install Node for your platform, then clone and build the Eve starter repository:

git clone
cd eve-starter
npm install

You can start the program switcher, which allows you to browse included example programs:

npm start

Or you can run a specific program by providing its path as an argument:

npm start -- path/to/program.js

Integrating Eve into an existing project

You can get Eve as an npm package

npm install witheve@preview

Then import Eve to use it in your project

import {Program} from "witheve";

Learning Eve

You can learn about Eve with the following resources:

Also, the mailing list archive is a good resource for help and inspiration. In particular, the Puzzles & Paradoxes series answers a lot of questions beginners face about the Eve langauge.

Eve is currently at a very early, "alpha" stage of development. This means the language, tools, and docs are largely incomplete, but undergoing rapid and continuous development. If you encounter errors while using Eve, don't worry: it's likely our fault. Please bring the problem to our attention by filing an issue.

As always, with pre-release software, don’t use this for anything important. We are continuously pushing to this codebase, so you can expect very rapid changes. At this time, we’re not prepared make the commitment that our changes will not break your code, but we’ll do our best to update you on the biggest changes.
