Julia Pkg Commands

The Julia package manager is called Pkg. It is used to install, update, and remove packages, as well as to manage the versions of packages in your project. The Pkg module is part of the standard library and is always available.

Ion forwards Julia's Pkg commands in the terminal, e.g

> ion add -h
Add dependencies to current environment

Usage: ion add [OPTIONS] [PACKAGE]...

Arguments:
  [PACKAGE]...  The package to add

Options:
  -g, --global  Add the package to the global environment
  -h, --help    Print help

and all Pkg commands will run as equivalent to having julia --project -e "using Pkg; ... by default, and there is a -g --global option to manage global shared environment.
