Programming word of the day

It works pretty much just like in any other language. You get to be more precise when you want, but (sometimes with a little extra effort) you can hide/throw away detail you don’t need.

For example, in Haskell, you can write

data Vec (n :: Nat) x where ...

And, say, have a function to add two vectors with the same length:

add :: Vec n Double -> Vec n Double -> Vec n Double

If you give it vectors which don’t provably have the same type, it won’t compile.

Let’s say you’re reading it from a file. You don’t know how large it is. Then what we can do is provide it as an existential type (sigma types in languages with dependent types proper):

data SomeVec x where
    VecLen :: KnownNat n => Proxy n -> Vec n x -> SomeVec x

(Proxy n is used to promote the natural number n into a type in Haskell; it’s a kludge that would be probably unnecessary in languages that support dependent types more-directly)

Now my function can be

readVec :: FilePath -> IO (SomeVec Double)

It will produce a vector, of some length that I don’t know. I’ll need to figure out aspects of that length in order to be able to use it in certain ways.

Now if I have two files, I have to check whether the vectors actually have the same length:

main = do
    VecLen len1 v1 <- readVec "vec1.txt"
    VecLen len2 v2 <- readVec "vec2.txt"
    case sameNat len1 len2 of
        Nothing -> error "vectors have different lengths"
        Just Refl -> print (add v1 v2)

Again, in a language with proper dependent typing I could just say len1 == len2 and throw that in an if-statement. We need to do a bit more in Haskell to convince the compiler that they’re actually the same.
