Instance Public methods
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.
1 2 | /(.)(.)(.)/.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
1 | pat.match(str) {|m| ...} |
instead of
1 2 3 | if m = pat.match(str) ...end |
The return value is a value from block execution in this case.
