What's this?

gets(eol=$/, limit=nil) public

Reads the next “line” from the stream. Lines are separated by eol. If limit is provided the result will not be longer than the given number of bytes.

eol may be a String or Regexp.

Unlike IO#gets the line read will not be assigned to +$_+.

Unlike IO#gets the separator must be provided if a limit is provided.
