This tutorial describes how to set up your system by installing julia, Mimi, and the Mimi registry.
There are various editors around that have julia support, including the following:
- IJulia adds julia support to the jupyter (formerly IPython) notebook system.
- VS Code has an excellent julia extension
- other editors such as Emacs and Sublime have julia extensions that add various levels of support for the julia language.
Once julia is installed, start julia and you should see a julia command prompt. Begin an interactive Julia session and enter the Package REPL, which is entered by typing
] and exited with a single backspace:
Next you should run a command that updates your system with the latest information about available packages. It is particularly crucial that you run this command at this point if this is the first time you are using Julia on your system. To run this command, execute the following in the package REPL:
Now to install the Mimi package, issue the following command from the Pkg REPL mode:
pkg> add Mimi
You only have to run this command once on your machine.
As we work to enhance and improve Mimi we will release new versions of the package. To make sure you always have the latest version of Mimi installed, we recommend that on occasion you run the
update command at the julia Pkg REPL. This will update all installed packages to their latest version (not just the Mimi package). To only update the Mimi package you may run the following, although we recommend you do a comprehensive update each time as indicated above.
pkg> update Mimi
When you start a new julia command prompt, Mimi is not yet loaded into that julia session. To load Mimi, issue the following command:
julia> using Mimi
You will have to run this command every time you want to use Mimi in julia. You would typically also add
using Mimi to the top of any julia code file that employs the Mimi API.
To access the models in the MimiRegistry, you first need to connect your julia installation with the central Mimi registry of Mimi models. This central registry is like a catalogue of models that use Mimi that is maintained by the Mimi project. To add this registry, run the following command at the julia package REPL:
pkg> registry add https://github.com/mimiframework/MimiRegistry.git
You only need to run this command once on a computer.
From there you will be add any of the registered packages, such as MimiDICE2010.jl by running the following command at the julia package REPL:
pkg> add MimiDICE2010
After taking the steps above you have prepared your system and are ready to run the next tutorials!
