ExtraMojo Docs

Also see any of the tests in the test_*.mojo files.

Add https://repo.prefix.dev/modular-community to your project channels:

# mojoproject.toml or pixi.toml

[project]
channels = ["conda-forge", "https://conda.modular.com/max", "https://repo.prefix.dev/modular-community"]
description = "Add a short description here"
name = "my-mojo-project"
platforms = ["osx-arm64"]
version = "0.1.0"

[tasks]

[dependencies]
mojo = "=25.5.0"

then run:

pixi add extramojo

Or directly by following these instructions.

See docs for numojo and just do that for this package until Mojo has true package / library support.

tl;dr;

In your project mojo run -I "../extramojo" my_example_file.mojo. Note the bit about how to add this project to your LSP so things resolve in VSCode.
