# Mapbox SDK Configuration Script for iOS and Android
# ===================================================
#
# Purpose:
# --------
# This script configures the development environment to download Mapbox SDKs
# for both iOS and Android builds. We use Mapbox to display maps in the App. As Mapbox SDKs
# are closed-sourced, we need to authenticate with Mapbox during the download.
#
# Background:
# -----------
# Engineers are required to obtain a secret token from Mapbox and store it on
# their development machine. This allows tools like CocoaPods for iOS or Gradle for Android
# to access the Mapbox SDK during the build process.
#
# The `.netrc` file for iOS Configuration:
# ----------------------------------------
# The token for iOS is stored in the `.netrc` file located in the user's home directory.
# This file is used in Unix-like systems to store credentials for remote machine access.
#
# The `gradle.properties` file for Android Configuration:
# -------------------------------------------------------
# The token for Android is stored in the `gradle.properties` file located in the .gradle directory
# in the user's home. This is accessed by the Android build system during the SDK download.
#
# How this script helps:
# ----------------------
# This script streamlines the process of adding the credential to both the `.netrc` and
# `gradle.properties` files. When executed, it prompts the user for the secret token and
# then saves it to the respective files along with other necessary information.\n
#
# Usage:
# ------
# To run this script, pass the secret Mapbox access token as a command-line argument:
# ./scriptname.sh YOUR_MAPBOX_ACCESS_TOKEN

# Use functions and variables from the utils script
source scripts/shellUtils.sh

NETRC_PATH="$HOME/.netrc"
GRADLE_PROPERTIES_PATH="$HOME/.gradle/gradle.properties"

# This function provides a user-friendly error message when the script encounters an error.
# It informs the user about probable permission issues and suggests commands to resolve them.
