# moss

Haskell client library for [Moss](https://theory.stanford.edu/~aiken/moss/).

## Example

In order to use Moss, you need to register on the Moss website. Once you have your access token, using the library is fairly easy:

```haskell
import Stanford.Moss

cfg :: MossCfg
cfg = defaultMossCfg {
    mossLanguage = Haskell,
    mossUser = "[YOUR ACCESS TOKEN HERE]"
}

main :: IO ()
main = do
    url <- withMoss cfg $ do
        addBaseFile "Skeleton" "Skeleton.hs"
        addFile "StudentA" "StudentA.hs"
        addFile "StudentB" "StudentB.hs"
        query "Test"
    print url
```

This example establishes a connection with Moss using Haskell as the selected programming language. We assume that some skeleton code (`Skeleton.hs`) has been made available to students and relevant parts from that file should be ignored for plagiarism checking. The example then uploads two students' submissions (`StudentA.hs` and `StudentB.hs`) before telling Moss to run the plagiarism check with `query` which eventually returns a URL to the results.
