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]
|

# => #<MatchData "hog" foo:"h" bar:"g">
|
||
m[:foo] # => "h"
|
||
m.offset('foo') # => [0, 1]
|

m[:bar] # => "g"
