#
# Simple script to install and also update FreeDATA in Linux
# To update FreeDATA, simply re-run the script in the same location
#
# Please note this script is not meant to cover all possible installations
# but hopefully can be used as a guide if you are installing on other 
# flavours of Linux
#
# Currently tested in Debian [11, 12], Ubuntu [22.04, 24.04], Fedora [40,41]
# Untested additions for Linux Mint [21.3]
# 
# First option passed is the branch of FreeDATA to run.  Defaults to main.
# Second option passed is the version of Hamlib to use.  Defaults to 4.5.5.
#
# Run this script by typing in the terminal (without the quotes):
# "bash install-freedata-linux.sh (FreeDATA-branch) (hamlib-version)"
#
# Examples:
#
# Install FreeDATA main branch and default Hamlib version:
# "bash install-freedata-linux.sh"
#
# Install FreeDATA develop branch and default Hamlib version:
# "bash install-freedata-linux.sh develop"
#
# Install FreeDATA develop branch and Hamlib version 4.6.2:
# "bash install-freedata-linux.sh develop 4.6.2"
#
# Install FreeDATA main branch and Hamlib version 4.6.2:
# "bash install-freedata-linux.sh main 4.6.2"
#
# This script creates three subdirectories in the directory it is run
# FreeDATA: Contains the FreeDATA software
# FreeDATA-venv: Contains the Python virtual environment
# FreeDATA-hamlib: Contains the hamlib libraries
#
# It also installs nvm and node into $HOME/.nvm
#
# FreeDATA config file is stored in $HOME/.config/FreeDATA/config.ini
# See the run-freedata-linux.sh for more details
