Test with GHC 8.4.3, GHC 8.6.1

[PabloReszczynski]

Hi! Browsing around for Hacktoberfest issues I came up with this project, which seem awesome!
If I would like to tackle this issue, do I just need to install ghc-8.4.3, add it to herms.cabal, run stack test and see if the tests still pass?

Hey there, @PabloReszczynski! This ticket is actually about using GHC in our Travis testing (which is also broken right now: #80). As noted in the code the setup is actually generated, using this project: https://github.com/haskell-CI/haskell-ci.

To tackle this issue would involve

1. installing haskell-ci
2. Changing the tested-with field of the herms.cabal file to include new GHC versions
3. Using haskell-ci to re-generate the .travis.yml file
4. Setting HADDOCK to false in the .travis.yml file

Let me know if you run into any difficulties!

haskell-ci is giving me this error:

../haskell-ci/make_travis_yml.hs:14:1: error:
    Failed to load interface for ‘Distribution.PackageDescription.Parse’
    It is a member of the hidden package ‘Cabal-1.24.2.0’.
    Use -v to see a list of the files searched for.

Thanks for giving it a shot!

It does seem to import that package: https://github.com/haskell-CI/haskell-ci/blob/master/make_travis_yml_2.hs#L72, though the Cabal file doesn't list any external dependencies: https://github.com/haskell-CI/haskell-ci/blob/master/haskell-ci.cabal#L34

What versions of cabal and ghc do you have installed?

[PabloReszczynski]

I'm using stack, so:

stack ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 8.4.3
