Welcome to Mojo 🔥

Mojo is a new programming language that bridges the gap between research and production by combining Python syntax and ecosystem with systems programming and metaprogramming features. Mojo is still young, but it is designed to become a superset of Python over time.

This repo includes source code for:

Mojo examples
Mojo documentation hosted at modular.com
The Mojo standard library

This repo has two primary branches:

The main branch, which is in sync with the last stable released version of Mojo. Use the examples here if you’re using a release build of Mojo.
The nightly branch, which is in sync with the Mojo nightly build and subject to breakage. Use this branch for contributions, or if you're using the latest nightly build of Mojo.

To learn more about Mojo, see the Mojo Manual.

Installing Mojo

Latest Released

To install the last released build of Mojo, follow the guide to Get started with Mojo.

Latest Nightly

The nightly Mojo builds are subject to breakage and provide an inside view of how the development of Mojo is progressing. Use at your own risk and be patient!

To get nightly builds, see the same instructions to Get started with Mojo, but when you create your project, instead use the following magic init command to set the conda package channel to max-nightly:

magic init hello-world-nightly --format mojoproject \
  -c conda-forge -c https://conda.modular.com/max-nightly

Or, if you're using conda, add the https://conda.modular.com/max-nightly channel to your environment.yaml file. For example:

[project]
name = "Mojo nightly example"
channels = ["conda-forge", "https://conda.modular.com/max-nightly"]
platforms = ["osx-arm64", "linux-aarch64", "linux-64"]

[dependencies]
max = "*"

And when you clone this repo, switch to the nightly branch because the main branch might not be compatible with nightly builds:

git clone https://github.com/modularml/mojo.git

git checkout nightly
