Converts pattern to a Regexp (if it isn’t already one), then returns a true or false indicates whether the regexp is matched str or not without updating $~ and other related variables. If the second parameter is present, it specifies the position in the string to begin the search.
"Ruby".match?(/R.../) #=> true "Ruby".match?(/R.../, 1) #=> false "Ruby".match?(/P.../) #=> false $& #=> nil
Returns a true or false indicates whether the regexp is matched or not without updating $~ and other related variables. If the second parameter is present, it specifies the position in the string to begin the search.
/R.../.match?("Ruby") #=> true /R.../.match?("Ruby", 1) #=> false /P.../.match?("Ruby") #=> false $& #=> nil
Returns sym.to_s.match?.
Tests whether the given pattern is matched from the current scan pointer. Returns the length of the match, or nil. The scan pointer is not advanced.
s = StringScanner.new('test string') p s.match?(/\w+/) # -> 4 p s.match?(/\w+/) # -> 4 p s.match?("test") # -> 4 p s.match?(/\s+/) # -> nil
Returns true iff the last match was successful.
s = StringScanner.new('test string') s.match?(/\w+/) # => 4 s.matched? # => true s.match?(/\d+/) # => nil s.matched? # => false
Returns the last matched string.
s = StringScanner.new('test string') s.match?(/\w+/) # -> 4 s.matched # -> "test"
