In this exercise you'll be processing log-lines.
Each log line is a string formatted as follows:
There are three different log levels:
You have three tasks, each of which will take a log line and ask you to do something with it. There are lots of ways to solve these tasks - choose your favourite methods from the examples above and see what you can come up with.
LogLineParser#message method to return a log line's message:
LogLineParser.new('[ERROR]: Invalid operation').message # => "Invalid operation"
Any leading or trailing white space should be removed:
LogLineParser.new("[WARNING]: Disk almost full\r\n").message # => "Disk almost full"
LogLineParser#log_level method to return a log line's log level, which should be returned in lowercase:
LogLineParser.new('[ERROR]: Invalid operation').log_level # => "error"
LogLineParser#reformat method that reformats the log line, putting the message first and the log level after it in parentheses:
LogLineParser.new('[INFO]: Operation completed').reformat # => "Operation completed (info)"
