mojo 0.26.2.0

The Mojo programming language

Get started | API docs | Changelog | GitHub

Mojo is a systems programming language specifically designed for high-performance AI infrastructure and heterogeneous hardware. Our vision for Mojo is to be the one programming language developers need to target diverse hardware—CPUs, GPUs, and other accelerators—using Python's intuitive syntax combined with modern systems programming capabilities. Of course, Mojo also provides strong interoperability with Python.

NOTE: Not available for Windows.

What's in mojo

The mojo package includes everything you need to program with Mojo, including the Mojo compiler, standard library, language server (LSP), debugger (LLDB), and more.

Not included but recommended is the Mojo extension for VS Code.

Get started with pip

1. Install Mojo:

   pip install mojo
   

   If you want the nightly build, instead use:

   pip install --pre mojo \
     --extra-index-url https://whl.modular.com/nightly/simple/
   

2. Write some code:

   # hello.mojo
   def main():
     print("Hello, World!")
   

3. Run the code:

   mojo hello.mojo
   

   Hello, World!
   

Using pip is great for existing Python-based environments, but if you're getting started for the first time, we recommend instead installing with pixi. For more information, see the Mojo install guide.
