Asynchronous completion for OCaml in vim or neovim

deoplete-ocaml's Issues

deoplete-ocaml doesn't respect deoplete#min_pattern_length

Maybe I'm doing something wrong, but deoplete shows completion suggestions all the time, not after typing 2 characters as it should. That is I get completion suggestions even after pressing spacebar or creating new line.

I'm using Neovim 2.3 dev.

asynchronous completion not working

Thank you for making great plugin!
I use vim8 on macos and debian(using windows subsystem linux).
On mac, I can use completion but on debian cannot.
In line 134 I find "output" is bytes but str.
I assume that it causes this trouble.
if "output" is decoded utf-8, It works.
Is it apropriate?

Deoplete explodes with “Key not present in Dictionary: complete_position” in a project opening JaneStreet Core?

So, if I open a file with these contents,

open Core

let () =
   print_string "Hello, world!"

… position my cursor on the last line, number 4, and then press o to start a new line, I immediately get all of these deoplete messages:

(Yes, each message is echoed twice — I have no idea why?)

The relevant part seems to be the neovim.api.nvim.NvimError: b'Vim(return):E716: Key not present in Dictionary: complete_position'; although I can't, for the life of me, figure out where that error is actually occurring.

The error doesn't occur when using Merlin's merlin#Complete as omnifunc, with Deoplete and deoplete-ocaml disabled (i.e. hit o as described above, then hit <C-x><C-o>.) Meanwhile, with Deoplete and deoplete-ocaml enabled, it works fine if I remove the open Core line. As far as I can tell, it's only the combination of deoplete-ocaml, a new blank line, and open Core, that produces the error.

Any doc to help me install this plugin?

At this moment, I put this deoplete_ocaml.py file in ~/.cache/dein/repos/github.com/Shougo/deoplete.nvim/rplugin/python3/deoplete

~/.c/d/r/g/S/d/r/p/deoplete (master|…) $ ls
__init__.py       deoplete.py       deoplete_ocaml.py exceptions.py     filter

I was wondering if maybe this is the right way to install, and how may I update this plugin automatically in future?

No completion after the dot?

I'm not sure if this is intended or if there's something missing on my setup. As it seems like no crashes are happening, I'm not sure how to fix this on my own, so I'm opening an issue.

I've enabled the DEBUG flag and put some debug messages of my own in the code.
I can see that no exception is happening, the list of candidates is just coming back empty.
I can also see that the query is being recognized correctly and the request is going through.

Moreover, top-level completions work well, but nested ones (after the dot) don't come through.
