Allow Cabal to recognize swarm as a library.

Allow Cabal to recognize swarm as a library.

Closes #1964.

[noahyor]

Why is docspec failing with such a strange error message? It compiled just fine the first time through.

@noahyor what does this library do?

I am no wiser from the Cabal message. Did you try running Docspec yourself?

It would be nice to add a comment here with a link to the Cabal issue you found that explains why this is a necessary workaround for now.

Just out of curiosity, even if do recognize it a library this way, it wouldn't really work as a library because there no exposed modules, right?

[byorgey]

No, you can import modules from the other libraries like swarm-lang that are marked as public. The point is that because of a Cabal bug it will not let you import anything at all from a package unless it has a default "main" library.

See haskell/cabal#8095 .

It seems like docspec does not like having an empty library component? I'm not sure...

[nitinprakash96]

Ah I see. Thanks a lot! I wasn't aware of that bug.
