* Add autoimport support for deoplete * Fix test_deoplete_source.py * Use callback instead of is_async for deoplete Shuogo, the author of Deoplete, does not recommend using the `is_async` option: > I think is_async is not recommended. It is not so useful and broken. > You should use callback system instead. Link: https://github.com/Shougo/deoplete.nvim/issues/1006#issuecomment-526797857 Incidentally, the same thread mentiones an issue started by w0rp: https://github.com/Shougo/deoplete.nvim/issues/976 The deoplete docs also say is_async is deprecated: > is_async (Bool) > If the gather is asynchronous, the source must set > it to "True". A typical strategy for an asynchronous > gather_candidates method to use this flag is to > set is_async flag to True while results are being > produced in the background (optionally, returning them > as they become ready). Once background processing > has completed, is_async flag should be set to False > indicating that this is the last portion of the > candidates. > > Note: The feature is deprecated and not recommended. > You should use callback system by > |deoplete#auto_complete()| instead.
