Instance Method Details

#remove(*patterns) ⇒ String

Returns a copy of this string with all occurrences of the patterns removed.

The pattern is typically a Regexp; if given as a String, any regular expression metacharacters it contains will be interpreted literally, e.g. '\\d' will match a backlash followed by 'd', instead of a digit.

Examples:

str = "This is a good day to die"
str.remove(" to die") # => "This is a good day"
str.remove(/\s*to.*$/) # => "This is a good day"
str.remove("to die", /\s*$/) # => "This is a good day"

Parameters:

  • *patterns (Regexp, String) —

    patterns to remove from the string.

Returns:
