match(p1, p2 = v2)
public
Returns a MatchData object describing the match, or nil if there was no match. This is equivalent to retrieving the value of the special variable $~ following a normal match. If the second parameter is present, it specifies the position in the string to begin the search.
/(.)(.)(.)/.match("abc")[2] #=> "b" /(.)(.)/.match("abc", 1)[2] #=> "c"
If a block is given, invoke the block with MatchData if match succeed, so that you can write
/M(.*)/.match("Matz") do |m| puts m[0] puts m[1] end
instead of
if m = /M(.*)/.match("Matz") puts m[0] puts m[1] end
The return value is a value from block execution in this case.
