Using JuliaSim Packages Locally via the JuliaHub Registry

To use JuliaSim packages on your local machine, you will need to add JuliaHub as a registry on your computer. To do this, you need to download an authentication token from the platform.

Adding the JuliaHub registry

Start a Julia session and install the PkgAuthentication package. This package can be used for both initial setup and to stay connected to the registry.

using Pkg
original_active_project = Base.active_project()
try
  withenv("JULIA_PKG_SERVER" => nothing) do
    Pkg.activate()
    Pkg.add("PkgAuthentication")
  end
finally
  Pkg.activate(original_active_project)
end

using PkgAuthentication
PkgAuthentication.install("juliahub.com")

Pkg.Registry.add()

This will open up a new browser window or tab and ask you to sign in to https://juliahub.com or to confirm authenticating as an already logged in user.

Once logged in, the browser tab can be closed. Julia will be authenticated with the package server at https://juliahub.com and download all available registries.

Staying connected to the JuliaHub registry

The authentication token will expire after a while, so it is convenient to enable an automatic mechanism for renewal. This can be achieved using the previously installed PkgAuthentication package, by adding the following snippet to your local <home directory>/.julia/config/startup.jl file.

Base.eval(Module(), quote
    using PkgAuthentication
    PkgAuthentication.install("juliahub.com")
end)

This will ensure that whenever a Pkg operation is performed that an up-to-date authentication token is available either silently or through another browser interaction.

Supported Packages

The following JuliaSim packages currently support usage through the JuliaHub registry:

• JuliaSimCompiler
• JuliaSimModelOptimizer
• JuliaSimControl

See the relevant package's documentation for more details.
