Returns the regexp that produced the match:

m = /a.*b/.match("abc") # => #<MatchData "ab">
m.regexp                # => /a.*b/

Returns an array of the capture names (see Named Captures):

m = /(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge")
# => #<MatchData "hog" foo:"h" bar:"o" baz:"g">
m.names # => ["foo", "bar", "baz"]

m = /foo/.match('foo') # => #<MatchData "foo">
m.names # => [] # No named captures.

Equivalent to:

m = /(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge")
m.regexp.names # => ["foo", "bar", "baz"]

Returns size of the match array:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m.size # => 5

Returns size of the match array:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m.size # => 5

Returns a 2-element array containing the beginning and ending offsets (in characters) of the specified match.

When non-negative integer argument n is given, returns the starting and ending offsets of the nth 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]

Returns a two-element array containing the beginning and ending byte-based offsets of the nth match. n can be a string or symbol to reference a named capture.

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
m.byteoffset(0)      #=> [1, 7]
m.byteoffset(4)      #=> [6, 7]

m = /(?<foo>.)(.)(?<bar>.)/.match("hoge")
p m.byteoffset(:foo) #=> [0, 1]
p m.byteoffset(:bar) #=> [2, 3]

Returns the offset (in bytes) of the beginning of the specified match.

When non-negative integer argument n is given, returns the offset of the beginning of the nth match:

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
# => #<MatchData "HX1138" 1:"H" 2:"X" 3:"113" 4:"8">
m[0]       # => "HX1138"
m.bytebegin(0) # => 1
m[3]       # => "113"
m.bytebegin(3) # => 3

m = /(т)(е)(с)/.match('тест')
# => #<MatchData "тес" 1:"т" 2:"е" 3:"с">
m[0]       # => "тес"
m.bytebegin(0) # => 0
m[3]       # => "с"
m.bytebegin(3) # => 4

When string or symbol argument name is given, returns the offset of the beginning for the named match:

m = /(?<foo>.)(.)(?<bar>.)/.match("hoge")
# => #<MatchData "hog" foo:"h" bar:"g">
m[:foo]        # => "h"
m.bytebegin('foo') # => 0
m[:bar]        # => "g"
m.bytebegin(:bar)  # => 2
