ddc.vim VS deoplete.nvim

Have a look at ddc.vim and denops.vim

There is shougo/ddc.vim by the same author

e.g:https://github.com/Shougo/ddc.vim

I use dense-analysis/Ale for code linting. Lately, I moved to update my tab completion from deoplete to Shougo/ddc.vim; the autocompletion of Ale is routed to ddc using statiolake/ddc-ale but the Ale autocomplete leaves things to be desired.

I was looking at ddc.vim and it looked somewhat similar to nvim-cmp. There's also multiple sources for it with no inbuilt ones. So, I was wondering if anyone has used both of them and could provide some pointers on a rough comparison between the both. Also, if there's any config file with sources for lsp, buffer, and other useful ones already setup, then could you share that too?

Sadly deoplete doesn't play well with 'some' asynchronous plugin sources (ex: vim-iced). I still got to try ddc.vim to see if things are easier and if middle word completion is done right.

I think in-the-wild examples like Ultisnips deoplete semshi (although they are advanced and somewhat complex) would also be good examples to learn how one can use python for writing plugins.

If you post your issue on https://github.com/Shougo/deoplete.nvim/issues, Shougo might be able to better assist you.

I have a problem with Deoplete and Vim-LSP completion (Python's Pylsp and Jedi-Language-Server). The suggestion is much less, and it also misses a lot of opportunities to suggest compared to Deoplete-Jedi, which literally defeats the former by a large margin. Is there a setting to make this duo works like deoplete with deoplete-jedi?

Someone made an issue on this question, with the author suggesting float-previewnvim.

This exactly why I keep using deoplete! Other completion plugins don't handle middle of word completion correctly.

As we can see, it's a deoplete issue. By reading the docs at https://github.com/Shougo/deoplete.nvim, under the requirements section, it needs nvim to be compiled with python support.

Hmm. Maybe I don't know what to look for (not an expert at vim), but I have searched the deoplete documentation and I can't see any options to allow as-you-type omnicompletion. There are things like external sources, but I don't need that. Everything is available from , I just need that to be automatic.

For me I've been using deoplete.nvim for everyday use and for a long time and will probably transition to [ddc.vim](https://github.com/Shougo/ddc.vim] which is the next iteration after deoplete from the same author and is very similar to cmp in terms of setup with user customization.

To my knowledge thats not possible with omnicompletion. For this you would have to use an auto-completion plugin. I am using compe because its fast, minimal and integrates well with the builtin nvim-lsp but there are many others. The most popular is probably coc. You could also check out deoplete.
