neocomplete preview window alternative

[Netherdrake]

Hi,

My issue is as follows: http://stackoverflow.com/questions/20164541/golang-vim-autocomplete-hints

I am wondering if you know how could I achieve this.

Thanks, your plugin is awesome!

[Shougo]

OK. I get it. I want to implement this feature. I don't like preview window feature, too.

[Netherdrake]

Thanks, sir, you are awesome!

[Shougo]

I added the feature. Please install echodoc and enable it.

[Netherdrake]

Thanks for quick response, but it doesn't seem to work for me. Here is my vimrc. https://bitbucket.org/furion/dotfiles

[Shougo]

You must upgrade neocomplete.

[Netherdrake]

I did.

[Netherdrake]

I managed to get it pop once but otherwise it doesn't work. Maybe its smt wrong with my config.

[Shougo]

It works for me. You should create minimal .vimrc. I will check it.

[Shougo]

Can you upload gif screenshot for your behavior?

[Netherdrake]

Nothing appears on status line on bottom, however neocomplete menu works fine. http://imgur.com/cFcpdqu

[Shougo]

I think it is your settings problem. But your .vimrc is too huge. You must reduce and minimize .vimrc and upload it.

[Netherdrake]

I disabled all of the plugins and all of my vimrc, now its just neocomplete and golang: http://pastebin.com/1Tw93UpM

And it still doesn't work. Could be something in my neocomplete config.

EDIT: I stripped down my .vimrc even further, still no luck: http://pastebin.com/JVaWRSt2

[Shougo]

Above code is not minimal. You must reduce codes more and more. Minimalist plugin is:

• echodoc
• neocomplete
• vundle
• gocode

only.

And your .vimrc settings also too huge.

OK. Minimal settings is like this:

set encoding=utf-8

" start vundler
filetype off
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()

Bundle "nsf/gocode"
Bundle "Blackrush/vim-gocode"

  Bundle "Shougo/neocomplete"
  Bundle "Shougo/echodoc.vim"

" enable all the plugins
filetype plugin indent on

  let g:neocomplete#data_directory = "~/.vim/tmp/swap"
  " Use neocomplete.
  let g:neocomplete#enable_at_startup = 1

  " Enable heavy omni completion.
  if !exists('g:neocomplete#sources#omni#input_patterns')
    let g:neocomplete#sources#omni#input_patterns = {}
  endif

  " golang fix
  let g:neocomplete#sources#omni#input_patterns.go = '[^.[:digit:] *\t]\.\w*'

Can you test it?

[Netherdrake]

Ok, I used your minimal sample, and it still doesn't work. I ran :BundleUpdate again, no new updates.

[Shougo]

OK. I get it. To use echodoc, you must set cmdheight to 2 in .vimrc

set cmdheight=2

[Netherdrake]

Ok, I am running the minimal sample and cmdheight=2, still no luck.

[Shougo]

" .vimrc
set nocompatible

let s:neobundle_dir = expand('~/.bundle')

set runtimepath+=~/work/neobundle.vim

call neobundle#rc(s:neobundle_dir)

set runtimepath+=~/work/neobundle.vim/
set runtimepath+=~/work/neocomplete.vim/
set runtimepath+=~/work/echodoc.vim/

NeoBundleLazy 'nsf/gocode', {
      \ 'rtp' : 'vim',
      \ 'autoload' : {
      \   'filetypes' : 'go',
      \ }}

let g:neocomplete#enable_at_startup = 1
let g:echodoc_enable_at_startup = 1

filetype plugin indent on

set completeopt+=menuone
set completeopt-=preview

set cmdheight=2

I tested it(using neobundle) and it works.

[Shougo]

let g:echodoc_enable_at_startup = 1

is needed.

[Netherdrake]

set encoding=utf-8

" start vundler
filetype off
set rtp+=~/.vim/bundle/vundle/
call vundle#rc()

Bundle "nsf/gocode"
Bundle "Blackrush/vim-gocode"

Bundle "Shougo/neocomplete"
Bundle "Shougo/echodoc.vim"

" enable all the plugins
filetype plugin indent on

set cmdheight=2
set completeopt+=menuone
set completeopt-=preview
let g:neocomplete#enable_at_startup = 1
let g:echodoc_enable_at_startup = 1

" Enable heavy omni completion.
if !exists('g:neocomplete#sources#omni#input_patterns')
let g:neocomplete#sources#omni#input_patterns = {}
endif

" golang fix
let g:neocomplete#sources#omni#input_patterns.go = '[^.[:digit:] *\t]\.\w*'

No luck.

[Shougo]

It may be Vim's version problem. Can you upgrade Vim?

In my environment, it works in minimal .vimrc.

[Shougo]

I think you should install neobundle and try my minimal .vimrc.

[Netherdrake]

I have Vim 7.4.52.

if has('vim_starting')
   set nocompatible               " Be iMproved
   set runtimepath+=~/.vim/bundle/neobundle.vim/
 endif

 call neobundle#rc(expand('~/.vim/bundle/'))

 " Let NeoBundle manage NeoBundle
 NeoBundleFetch 'Shougo/neobundle.vim'

NeoBundle "nsf/gocode"
NeoBundle "Blackrush/vim-gocode"
NeoBundle "Shougo/neocomplete"
NeoBundle "Shougo/echodoc.vim"

set cmdheight=2
set completeopt+=menuone
set completeopt-=preview
let g:neocomplete#enable_at_startup = 1
let g:echodoc_enable_at_startup = 1

filetype plugin indent on

No luck

[Shougo]

You must select candidate by <C-y>. I think your key operations are wrong.

[Netherdrake]

Doesn't matter. The minimal vimrc doesn't have the key-bindings setting. I tried it on 2 machines, both don't work.

My second machine is:

[Shougo]

Operations:

1. input "fmt." popup is shown
2. Select candidate "Scan(" by <C-n>.
3. Close popup by <C-y>.
4. Printed candidate arguments.

[Netherdrake]

Oh. <C-y> does the trick. Thank you!

[incorvia]

Is it not possible to autocomplete the function arguments rather then putting it in a scratch or printing it using echodoc? Having it inline would obviously be amazing.

[Shougo]

Having it inline would obviously be amazing.

I don't want to implement it. Yes, some plugins implement it(like jedi-vim). But, it is complicated feature.

[incorvia]

Thank you for the response and all the great work.

[sirfz]

Is there a specific configuration for echodoc with jedi? Doesn't seem to work for me. (tried with increased cmdheight and also noshowmode). Ctrl+y doesn't display anything.

[Shougo]

jedi does not support echodoc. To support it, you must write Vim script code like neocomplete.
