network-uri-static is a small utility for Haskell that allows you to declare static URIs in type-safe manner.
When you declare a static URI, you need to either use Maybe URI or use URI and give up type safety.
safeButWrappedInMaybeURI :: Maybe URI
safeButWrappedInMaybeURI = parseURI "http://www.google.com/"
directButUnsafeURI :: URI
directButUnsafeURI = fromJust $ parseURI "http://www.google.com/"This library allows you to write static URIs in type-safe manner by checking URIs at compile time using template haskell.
Now, you can write the following.
directAndSafeURI :: URI
directAndSafeURI = $$(staticURI "http://www.google.com")You can even use a quasi quote if you'd like.
directAndSafeURI :: URI
directAndSafeURI = [uri|"http://www.google.com"|]These two expressions emit an error at compile time if a specified URI is malformed.
