RetroDECK/functions/logger.sh

#!/bin/bash

# This script provides a logging function 'log' that can be sourced in other scripts.
# It logs messages to both the terminal and a specified logfile, allowing different log levels.
# The log function takes three parameters: log level, log message, and optionally the logfile. If no logfile is specified, it writes to retrodeck/logs/retrodeck.log

# Example usage:
# log w "foo" -> logs a warning with message foo in the default log file retrodeck/logs/retrodeck.log
# log e "bar" -> logs an error with message bar in the default log file retrodeck/logs/retrodeck.log
# log i "par" rekku.log -> logs an information with message in the specified log file inside the logs folder retrodeck/logs/rekku.log

    local logfile="${3:-$logs_folder/retrodeck.log}" # Use specified logfile or default to retrodeck.log
