Installation

RainMaker.jl is an official Julia package, so to install the latest version you can simply type

julia> ] add RainMaker

Where ] opens Julia's package manager Pkg.jl which changes the prompt to (@v1.11) pkg>, exit the package manager with backspace. Pkg.jl is also a package itself, so you can alternatively do

using Pkg
Pkg.add("RainMaker")

RainMaker.jl depends on (among others)

• SpeedyWeather.jl
• Makie.jl and its backend CairoMakie for plotting

While they are automatically installed, you will also want to install SpeedyWeather explicitly via

julia> ] add SpeedyWeather

or, again, using Pkg; Pkg.add("SpeedyWeather"). So that

using SpeedyWeather

also just works as dependencies are otherwise hidden for direct usage.
