Hi, Here's a patch for something I've been missing in the Search action. It makes it possible to create your own search engine which uses a function to transform a search query into a URL instead of joining two strings. You can also easily connect many search engines into one that takes a query with a prefix to identify which of the engine to use. There's also a modifier which will take a search engine and wrap it so that if the search term is a URL it will go directly to the address (useful with selectSearch)
Sorry for my code. I'm new to haskell.
A quick review: all '[Char]' should be replaced by 'String'. Is it possible to improve: +> searchFunc ('w':'i':'k':'i':':':x) = "http://en.wikipedia.org/wiki/" ++ (escape x) +> searchFunc s@('h':'t':'t':'p':':':'/':'/':x) = s with a guard instead? pattern-matching on Strings is, as you can see, rather unpleasant and a little confusing because of the ':' + @searchFunc :: [Char] -> [Char]@ here searches for a word in wikipedia if it has a prefix I would usually include the type sig in the code itself, as it makes the code more 'durable' if you will when copied, and makes the prose more readable. In general, this patch looks worthwhile (although I doubt I'll use the more advanced functionality). - -- gwern -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAkl93TkACgkQvpDo5Pfl1oJumQCcDzBmn2hndjpBfhY7dMjb3Reo suwAoIYeGPG8TFq/zBM/7xiS/TcQ8Rxr =hkBf -----END PGP SIGNATURE-----
