ghc-mod not picking up cabal settings #53

Open pjonsson opened 10 years ago

pjonsson commented 10 years ago

Not sure if this is our fault or a problem upstream, so reporting it here for starters.

https://github.com/Feldspar/feldspar-language needs -fcontext-stack=100 which is specified in the cabal file. ghc-mod does not seem to pick that up automatically, so Constructs.hs:217 gets a red mark on render relating to that context-stack overrun.

I'm using ghc-mod 5.0.1 compiled with ghc 7.8.3. I didn't need the context stack parameter with ghc 7.6.x.

This ticket is blocked on the second bullet of #28.

This can be achieved similarly to how it is done for #56. However, one prerequisite will be to have a different instance of ghc-modi running for each cabal component instead of one for each IntelliJ module.

These could be spawned lazily and possibly garbage collected.
Another added benefit to making this change will be removing the requirement of having one IntelliJ module per Cabal file (also helping resolve #222).
It could more than likely be implemented as a ProjectComponent, similar to HaskellCompletionCacheLoader.
