This snap is intended to provide an easy-to-install package of the ROOT framework for the home user. It comes bundled along with Python 3.8/PyROOT and Jupyter/JupyROOT notebook capability. NumPy, SciPy, Pandas and Matplotlib are bundled with the Python environments.
Snaps are container packages for easy application deployment, designed to be consistent and reliable across different host distributions. They additionally impose some strong sandboxing for security. One caveat of this sandboxing is that this package can only read/write to your
$HOME directory, or via specific network protocols. It is highly advised that you place all your data files in your
$HOME directory to be accessible.
Users are encouraged to use the command
snap info root-framework to see the binaries available to them from the ROOT framework. By default, ROOT can be accessed with the command
root-framework. Users may wish to use an alias so that it is simply accessible with
root. Similarly, by default, other binaries such as hadd can be accessed with
root-framework.hadd, which again can be aliased as
hadd. Jupyter notebook support can be utilised with
root-framework --notebook, or
root --notebook if aliased.
sudo snap alias root-framework root
sudo snap alias root-framework.hadd hadd
Because snaps are containers and don't affect the host system, using PyROOT with
import ROOT will not work in a system Python shell. Users are encouraged to use
root-framework.pyroot to access the containers' Python shell, where
import ROOT would become available. Again, this can be aliased for simple usage such as
sudo snap alias root-framework.pyroot pyroot
