# Star Citizen's Linux Users Group Helper Script
############################################################################
#
# Greetings, Space Penguin!
#
#
# This script is designed to help you manage and optimize
# Star Citizen on Linux.
#
# Features:
#
# - Check your system for optimal settings and
# change them as needed to prevent crashes.
#
# - Install Star Citizen using a bundled Lutris install script
#
# - Easily install and remove Lutris wine Runners and DXVK versions.
#
# - Qickly wipe your Star Citizen USER folder as is recommended
# by CIG after major version updates.
# It will back up your exported keybinds, delete your USER folder,
# then restore your keybind file(s).
#
# - Get a random participating LUG member's Star Citizen referral code.
#
# - Supports both the LIVE and PTU environments.
#
# - Zenity menus are used for a GUI experience with a fallback to
# terminal-based menus where Zenity is unavailable.
#
#
# To export your keybinds from within the game, go to
# Options->Keybindings->Control Profiles->Save Control Settings
#
# To import your keybinds from within the game, select them from the list:
# Options->Keybindings->Control Profiles
#

# Display a menu to the user.
# Uses Zenity for a gui menu with a fallback to plain old text.
#
# How to call this function:
#
# Requires the following variables:
# - The array "menu_options" should contain the strings of each option.
# - The array "menu_actions" should contain function names to be called.
# - The strings "menu_text_zenity" and "menu_text_terminal" should contain
# the menu description formatted for zenity and the terminal, respectively.
# This text will be displayed above the menu options.
# Zenity supports Pango Markup for text formatting.
# - The integer "menu_height" specifies the height of the zenity menu.
# - The string "menu_type" should contain either "radiolist" or "checklist".
# - The string "cancel_label" should contain the text of the cancel button.
#
# The final element in each array is expected to be a quit option.
#
# IMPORTANT: The indices of the elements in "menu_actions"
# *MUST* correspond to the indeces in "menu_options".
# In other words, it is expected that menu_actions[1] is the correct action
# to be executed when menu_options[1] is selected, and so on for each element.
#
# See MAIN at the bottom of this script for an example of generating a menu.
