check if string starts with a timestamp and capture suffix in ruby

In Ruby, you can use regular expressions to check if a string starts with a timestamp and capture the suffix. Here's an example code snippet:

main.rb
timestamp_regex = /^(\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}) (.*)/
string = "2021-05-01 14:23:45 This is the suffix"

if match = timestamp_regex.match(string)
  timestamp = match[1] # "2021-05-01 14:23:45"
  suffix = match[2] # "This is the suffix"
else
  puts "String does not start with a timestamp"
end
303 chars
10 lines

In this example, the timestamp_regex variable is a regular expression that matches a string that starts with a timestamp in the format "YYYY-MM-DD HH:MM:SS", followed by a space and any other characters (.*).

The match method is called on the regular expression with the string variable as the argument. If there is a match, it returns a MatchData object, which can be used to extract the timestamp and suffix using the capture groups (()).

If there is no match, the code outputs a message indicating that the string does not start with a timestamp.
