I use matching URLs in a part of my code. Now I use regular expressions for this. This is fine, but does not always produces “nice”, simply readable patterns. Is there any language defined for matching URLs? It should be like this: http://*.example.com/* so simply wild-cards and things useful for URL would be there.

The best would if these expression can be simply transformed to regexp. Do you know specification for such a language, or even an implementation, preferably for ruby.. otherwise I implement it myself… the key is the readability of the patterns. Thanks for help!

    You’d have to carefully work your syntax out before you begin. At first glance, what you intend would be easily achieved by translating your syntax into ordinary regexes:

    s = 'http://*.example.com/*' #=> "http://*.example.com/*"
r = Regexp.compile("^#{Regexp.escape(s).gsub('\*','.*')}$") #=> http:examplecom
'http://test.example.com/path/to/doc.html' =~ r #=> 0
'http://test.example2.com/path/to/doc.html' =~ r #=> nil
