Deoplete.nvim: Completions from other buffers

[monkoose]

Problems summary

Completions from other buffers works only when you previously edit(current session) unfocused buffer.
Vim with almost identical config and neocomplete works fine.
Even <C-x><C-p> doesn't help, because it shows nothing, but if you first delete one letter with <BS> when there is no pum(you don't need to delete when pum didn't popup for a current word), then you can complete from other buffers with <C-p> only for this word.

Expected

deoplete should complete words from other buffers atleast for buffers with same filetype(related to doc)

Environment Information

Linux 4.4.5-1-ARCH SMP PREEMPT Thu Mar 10 07:38:19 CET 2016 x86_64 GNU/Linux

• OS:
• Neovim version:
  0.1.3 with python3-neovim 0.1.7

Provide a minimal init.vim with less than 50 lines (Required!)

" Your minimal init.vim
set runtimepath+=~/path/to/deoplete.nvim/
let g:deoplete#enable_at_startup = 1

The reproduce ways from neovim starting (Required!)

1. With mininal init.vim open two files in nvim
   :e /path/to/file1.txt or any other filetype
   :e /path/to/file2.txt same filetype
2. file1.txt must have some content, file2.txt can be empty.
3. Do not edit file1.txt, then try to type some words in file2.txt from file1.txt

[wsdjeg]

yeah,can confirm,deoplete's buffer source can not load words from file1.txt,but neocomplete works well

EDIT: but in neovim,ctrl+p can complete words from file1.txt,it is same as vim ,and no issues.

[Shougo]

Implemented.

[wsdjeg]

@Shougo thanks for your work

[monkoose]

@Shougo Thank you a lot. Works for me.
But seems like there is a problem with refreshing(screen blinks, even with vb disabled) when deoplete can't find completions for a current word. I will open a new issue.

[ZachCheung]

same problem with latest deoplete.

Please upload the reproduce instruction.

How to reproduce the problem from neovim/Vim startup (Required!)

1. open file1, do nothing or input words without :w
2. open file2, try to input word prefix of file1, no expected completion pop-up
   
   
   
   1. switch to file1, :w and switch back to file2, completion pop-up
   
   

[Shougo]

Please don't use "open files" description.
It must be Vim commands.

"switch to file1" is also fuzzy instruction.
It is not reproduce-able for me.

Can you ignore your report??

[Shougo]

Please see original reproduce instruction.
Please compare your one.

I ignore the fuzzy instruction.

[ZachCheung]

sorry about fuzzy instruction.

1. nvim file1.txt
2. :vs file2.txt
3. try to input word prefix of file1.txt, no expected completion pop-up
4. <C-w>w switch to file1.txt, :w
5. <C-w>w switch to file2.txt, repeat step 3, completion pop-up

[Shougo]

OK. So I get it.
I will fix it later.

[Shougo]

I have fixed it.

[ZachCheung]

I have fixed it.

Thanks, it works!

[ZachCheung]

btw, is it able for deoplete to auto complete unsaved changes in other buffers?

reproduce steps:

1. nvim
2. :e file1, write some words without :w
3. :vs file2, input word of file1, no expected completion pop-up

[Shougo]

OK. I have added the support.
Please use the latest version.

[ZachCheung]

seems doesn't work, have use the latest version.
