Summary

Installs the Julia programming language, along with juliaup (a version manager for Julia).

Requires

• Linux OS

Description

This role installs juliaup, the latest julia, and makes available a shared Julia packages depot for all users. The steps it takes are:

1. Installs juliaup to the shared environment (/usr/local/uu/env/julia by default).
2. juliaup will automatically install the latest stable version of julia.
3. We symlink the installed julia interpreter to /usr/local/bin/julia so all users can use it.
4. We set the JULIA_DEPOT_PATH and JULIA_LOAD_PATH variables for all users such that julia will detect the shared depot. However, the shared depot is read-only. When users install new packages, they will be installed into the user’s own julia depot directory (~/.julia by default).

Variables

• julia_shared_env_path: String. Path to the shared julia package depot. Default: /usr/local/uu/env/julia
