completion suggestions from all modules

[shmish111]

It seems completion items only come from the current file, I would like to see suggestions based on all exposed modules including from dependencies that are in my cabal file. After playing with HLS for a while and coming from purescript I would say this is the biggest missing feature for me personally.

+1 for it! IIRC, TypeScript Language Server also provides such a feature, provides a symbol completion not only for local and imported modules, but also for all the modules in package dependency and adds missing imports automatically.
Since the size of dependency can tremendously slow down the generation of completion candidate, it might make sense to generate candidates somewhat lazily, or just provide a configuration option to enable/disable such an aggressive completion.

I don't think a list of exposed symbols would ever be that big, it could be indexed on startup possibly. If you wanted to include transitive dependencies that need to be exposed in the cabal file (which would be cool) it might be a bit big I guess.

I wonder if this could be feasible using the new hiedb

+1. Really liking HLS so far, but agree that suggesting outside of the current file would be great.

This was discussed in #1327 as well

@shmish111 @mmgeorge it seems #1327 has some interesting discussion about that so i am gonna close this one, you can track the progress in that issue. Thanks!
