Direct communication with ghc-modi #6

Closed iquiw closed 8 years ago

iquiw commented 10 years ago

Currently, company-ghc borrows ghc-mod variables and modifies them by adding text properties. It is not polite. I would like to change it by communicating with ghc-modi directly via ghc-sync-process.

Once after ghc-modi supports "-d" and "-o" options like ghc-mod, we can remove call of ghc-get-info and add operators into candidates.

One down side is we may have duplicate set of keywords in ghc-mod and company-ghc.

Initial implementation is pushed to direct-comm branch [1].

TODO

It still uses ghc-get-info when type information is not got from ghc-modi browse -d.
There are duplicate information in ghc-mod and company-ghc.
Operator support, which needs enhancement in ghc-mod.

Since ghc-get-info now pops up error if the current buffer contains error, ghc-get-info is not usable for company's meta command.

With this branch,

Use type information from ghc-modi browse -d.
Change default value of company-ghc-show-info to nil.

ghc-get-info is not used in default. I will merge it.
