Setup the FUSE environment

Julia installation

We highly recommend using the Juliaup manager to install Julia

Once installed, restart your termninal to pick-up the julia executable.

FUSE and related packages are registered at the FuseRegistry. For installation start your Julia interpreter by typing julia at the terminal, then:

Add the FuseRegistry and the FUSE package as you would for any other julia package (for a fresh install this can take 20+ mins):

using Pkg
Pkg.Registry.add(RegistrySpec(url="https://github.com/ProjectTorreyPines/FuseRegistry.jl.git"))
Pkg.Registry.add("General")
Pkg.add("FUSE")

Now you should be able to import the FUSE package:
```
using FUSE
```
Install the fusebot utility to simplify install/updates later on. Now fusebot should be a command that you can type anywhere from the terminal.
```
FUSE.install_fusebot()
```
Run the regression tests (optional, this can take 1h+)
julia ] test FUSE
Exit julia and clone FUSE examples in the current working directory. To see/run those .ipynb files, you'll need to use Jupyter-Lab or VScode.
```
fusebot install_examples
```

Tip

Become familiar with how managing Julia packages works.

You will need to install jupyter-lab if that's not already available on your system
Install the IJulia package by running:
```
fusebot install_IJulia
```
Note
Run fusebot install_IJulia every time a new julia version is installed.
This will setup the single- and multi-thread julia kernels in Jupyter.
The number of threads of the multi-threaded julia kernels can be set via the JULIA_NUM_THREADS environmental variable.
Start a new Jupyter-lab session (this should open a web-browser page with Jupyter running)
```
jupyter-lab
```
Now you can browse the examples in the FuseExamples folder that you have cloned, and take a tour of the example Jupyter notebooks there.
