This is a gem to create regexp objects from wildmat patterns
All wildmat patterns match an entire string. The pattern matching operations are as follows: (from wikipedia http://en.wikipedia.org/wiki/Wildmat)
- Asterisk (*) to match any sequence of zero or more characters.
- Question mark (?) to match any single character.
- Set of specified characters. It is specified as a list of characters, or as a range of characters where the beginning and end of the range are separated by a minus (or dash) character, or as any combination of lists and ranges. The dash can also be included in the set as a character if it is the beginning or end of the set. This set is enclosed in square brackets. The close square bracket (]) may be used in a set if it is the first character in the set.
- Negation of a set. It is specified the same way as the set with the addition of a caret character (^) at the beginning of the test string just inside the open square bracket.
- Backslash (\) character to invalidate the special meaning of the open square bracket ([), the asterisk, backslash or the question mark. Two backslashes in sequence will result in the evaluation of the backslash as a character with no special meaning.
require 'wildmat'
regexp = Wildmat.to_regexp("[0-9]*")
match_data = regexp =~ "0123456"
- wildmat gem
- gem install wildmat
