When non-negative integer argument n
is given, returns the starting and ending offsets of the n
th match:
m = /(.)(.)(\d+)(\d)/.match("THX1138.") # => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8"> m[0] # => "HX1138" m.offset(0) # => [1, 7] m[3] # => "113" m.offset(3) # => [3, 6] m = /(т)(е)(с)/.match('тест') # => #<MatchData "тес" 1:"т" 2:"е" 3:"с"> m[0] # => "тес" m.offset(0) # => [0, 3] m[3] # => "с" m.offset(3) # => [2, 3]
When string or symbol argument name
is given, returns the starting and ending offsets for the named match:
m = /(?<foo>.)(.)(?<bar>.)/.match("hoge") # => #<MatchData "hog" foo:"h" bar:"g"> m[:foo] # => "h" m.offset('foo') # => [0, 1] m[:bar] # => "g" m.offset(:bar) # => [2, 3]
