I am using Intero under emacs to edit my new Haskell project. I added an import to a third-party library to my code to see if Intero would automatically add the necessary dependency, but it didn't. So I edited the .cabal file manually to add the necessary dependency. Now what do I do - short of restarting emacs?
I've tried running cabal install --dependencies-only; cabal configure at the command line and they ran successfully, but the flycheck buffer still shows an error.
All that is necessary is to run
M-x intero-restart
in emacs.
Intero uses stack which has its own private sandbox for each package you are developing, so cabal install --dependencies-only isn't needed or useful.
