denite.nvim's Introduction

denite.nvim

Note: Active development on denite.nvim has stopped. The only future changes will be bug fixes.

Please see ddu.vim.

Note: Denite.nvim does not define any of default mappings. You need to define them.

Please read help for details.

About

Denite is a dark powered plugin for Neovim/Vim to unite all interfaces. It can replace many features or plugins with its interface. It is like a fuzzy finder, but is more generic. You can extend the interface and create the sources.

Some things you can do with it include:

Opening files
Switching buffers
Inserting the value of a register
Changing current directory
Searching for a string

Unite.vim was meant to be like Helm for Vim. But the implementation is ugly and it's very slow.

Denite resolves Unite's problems. Here are some of its benefits:

Theoretically faster because the main process is executed by Python
Theoretically more stable because no other processes can be performed when it runs.
The implementation is simpler than unite
Has greater potential to implement new features
Python3 is easier to work with than Vimscript
There are a lot of useful tools to keep code simple (linter, tester, etc...) in Python3.
Unite is officially obsolete, minor bugs (or even major bugs) are not fixed anymore

Requirements

Denite requires Neovim 0.4.0+ or Vim 8.0+ with if_python3. If :echo has("python3") returns 1, then you're done.

Note: Please install/upgrade msgpack package (1.0.0+). https://github.com/msgpack/msgpack-python

Note: You need to install Python 3.6.1+.

For neovim:

You must install "pynvim" module with pip

pip3 install --user pynvim

If you want to read the pynvim/python3 interface install documentation, you should read :help provider-python.

For Vim8:

Please install nvim-yarp plugin for Vim8. https://github.com/roxma/nvim-yarp

Please install vim-hug-neovim-rpc plugin for Vim8. https://github.com/roxma/vim-hug-neovim-rpc

You must install "pynvim" module with pip

pip3 install --user pynvim

For Windows users

Install Vim from Vim Win32 Installer releases
Download Python latest embeddable zip file and copy the all files in the zip file to the folder where you installed Vim.

Note: You need to do 1. and 2. with the common-arch files (x86 or x64).

Installation

For dein.vim

call dein#add('Shougo/denite.nvim')
if !has('nvim')
  call dein#add('roxma/nvim-yarp')
  call dein#add('roxma/vim-hug-neovim-rpc')
endif

For vim-plug

if has('nvim')
  Plug 'Shougo/denite.nvim', { 'do': ':UpdateRemotePlugins' }
else
  Plug 'Shougo/denite.nvim'
  Plug 'roxma/nvim-yarp'
  Plug 'roxma/vim-hug-neovim-rpc'
endif

denite.nvim's Issues

Incremental Output from Source

Is it possible to give incremental output from a source? Say I have a really large grep that I'm doing, and I'd like the results to appear as they are found, not once they are all found?

Is this what you mean by asynchronous sources support in the TODOs?

Please support vim and neovim

Especially given that neovim isn't so stable on windows yet I would love to see denite.vim working in vim too might be with a fallback to using vimproc or job/channels.

Action name completion is not working

Warning: I will close the issue without the minimal init.vim and the reproduce ways.

Problems summary

Action name completion in normal mode is not working, if I canceled anything once confirmed.

:Denite file_rec
move normal mode by <C-o> and <TAB>
I input 'de' and <TAB> (expecting 'default').

and completed 'default' (it's works)
Next, I erase 'default' (by backspace key) and input 'y'
and input <TAB> for completion (expect 'yank')
but, completion is not working.

About quit_buffer operation

Problems summary

@Shougo Thanks for the awesome plugin.

What do you think to use bd rather than close! in the quit_buffer?
An empty denite buffer seems left in buffer list after we get done with denite.

Expected

No empty denite buffer left in buffer list

filter_project_files does not work.

Problems summary

I try filter_project_files future.
But it does not work with below settings.

call denite#custom#source('file_rec', 'matchers',
\ ['matcher_fuzzy', 'matcher_project_files'])

It seems that context['path'] isn't set in gather_candidates.

Expected

Set filter project to .git exists directory.

Denite file_rec

Ability to disable highlight on file_rec match.

I want to upgrade Denite to the master branch but I'm uncomfortable with glaring highlight on the matched file names. Is there any way to disable this highlight on file_rec matches? Thanks.

And I think highlight on the matched file names with file_rec should be disabled by default. Because matching changes on the fly as we type and using highlight the reflect those changes hurts the eyes.

Cancel operation for Denite grep

@Shougo thanks for awesome plugin;)
Denite grep is doing quite well right now, but it lacks of the ability to cancel the request.

The scenario and expectation: Enter Denite grep command and it prompts Pattern:, denite should cancel the grep operation if key <esc> or combo key<C-c> is being pressed.

How to map a Alt key?

I want to map Alt-c key, use the following command:

cal denite#custom#map('insert', '', 'delete_backward_char')

but it didn't work.

denite window resizes other windows

FYI. I don't know whether a fix is impossible or readily apparent to anyone. I'm posting this to confirm either case, otherwise I'll take a stab at a solution/PR when I have time, and this issue will serve as a reminder and starting point.

Problems summary

Split view into 3 windows.

:vsplit | wincmd l | split | wincmd h
Open denite window.

:Denite buffer
Notice two right windows shifted up and evenly split available vertical space above the denite window.
Close denite window.

Esc
Notice upper right window remains unchanged. Lower right window fills vertical space from absent denite window.

If the lower right window has a :terminal, over time it eventually fills all the vertical space. I cannot confirm, yet, whether :terminal matters. I just happened to observe this behavior while programming.

Here's an ascii screenshot to illustrate the issue.

  Step 1          Step 2          Step 4
┌────┬────┐     ┌────┬────┐     ┌────┬────┐
│9x4 │4x4 │     │7x4 │3x4 │     │9x4 │3x4 │  <- Sometimes split will end up here
│    │    │     │    │    │     │    │    │     when lower right window is :terminal.
│    │    │     │    │    │     │    │    │
│    │    │     │    ├────┤     │    ├────┤  <- Split now here
│    ├────┤     │    │3x4 │     │    │5x4 │  <- Expected split back here
│    │4x4 │     │    │    │     │    │    │
│    │    │     │    │    │     │    │    │
│    │    │     ├────┴────┤     │    │    │
│    │    │     │ Denite! │     │    │    │
└────┴────┘     └─────────┘     └────┴────┘

Expected

Case 1 (best): opening denite window doesn't affect dimensions of existing windows, other than the shrinking windows that otherwise overlap to make room for the denite window.

Case 2 (better): windows return to original sizes as seen before denite window opened.

Case 3 (good): windows resize to equally distribute vertical space from absent denite window, just as they resized when the denite window appeared.

Additional Observations

The resize behavior varies depending on which window has keyboard focus. After Step 1, move focus to the upper-right :wincmd l, notice after Step 4 the upper right window returns to its original size.

matcher_ignore_globs does not ignore files properly

Problems summary

Ignoring globs in file_rec source will still scan all the ignored globs and makes the whole search less performant.

Expected

The ignored globs should not be scanned at all.

The reproduce ways from neovim starting (Required!)

I cloned this repository and run npm install: https://github.com/ember-cli/ember-cli. Can be tested with any directory that contains a rather large node_modules directory.

Call :Denite file_rec
Type something

With the ignore_globs matcher enabled typing will react very slowly and the total number of files that is displayed is the total number of files in the directory and not the total number of files after filtering out the ignored globs. In another project I even have the problem that scanning never stops. I cannot investigate why and I wasn't able to reproduce this with this smaller example.

It should be possible to completely ignore some globs as it is possible with ctrl-p

togglable preview

Problems summary

do_action:preview is very nice!
But I want to close preview window if file opened in current preview window is selected line in candidates.

I worked around by these changes.
https://github.com/Shougo/denite.nvim/compare/master...pocari:feature-toggle-preview?expand=1

Colud you implement this feature?

[SUGGESTION] Automatic Documenation

Hey Shougo,

I was thinking maybe there might be a way to generate some of the documentation for denite from the python files of the sources. Would you be interested in something like that? I could take a look at it if you would like. I have a couple ideas from some documentation generators I have seen in the past that are used with Python.

This would hopefully keep your documentation / help documents up-to-date with the latest source, without you having to spend the time updating the documentation.

Denite loses statusline after file preview

After previewing a candidate, Denite window stops updating statusline.

Notice the statusline change:

My window settings are set winwidth=50 winminwidth=8 winheight=13 winminheight=3

There should be support for actions that "do not hide the Denite window", currently only the preview action acts this way, but it would be great for other kind actions, like https://github.com/rafi/vim-denite-mpc when selecting a song, it would be nice to have denite stay open and "refresh".

RFC: What do you think about relying on vim-rplugin for keeping Vim 8 compatibility?

Problems summary

Currently denite.vim support Vim 8 by extending vim module directly but

vim is shared to all plugins so once your approach got famous, there would be tons of variation of vim.call() implementations and each other will be conflict
vim.vars, vim.options or whatever returns bytes instead of str in Python 3 and it would cause Unicode encode/decode error

RFC

Recently I made vim-rplugin to solve all problems above.
So what do you think about relying on that plugin to support Vim 8? If you are OK with this idea, I will implement the feature sometime ;-)

Pros.

You can remove most of code for Vim 8 so the code become more simple
It wrap vim module rather than extend so that vim.call() always returns what you want.
It automatically decode bytes to str so you don't have to change codes for Neovim and Vim 8

Cons.

User who want to use denite.nvim in Vim 8 need to install lambdalisue/vim-rplugin as well.
Performance may decrease in Vim 8 while vim-rplugin use Proxy strategy

multiple key mappings not working

Hi,

Im trying to map jk to enter normal mode by adding the following mapping:

call denite#custom#map('insert', 'jk', 'enter_mode:normal')

However the mapping is not working. Changing it to a single key mapping works though.

Thanks,
A

Fuzzy search

What do you think to add one of this packages to do fuzzy search?

I have been following you and your vim plugin development for some time, and I would like to help with this next project in any way that I can. Please let me know if there is anything I can do in the development or testing of this plugin.

[feature request] vertical preview

Would it be possible to implement a vertical preview option?

This was a really helpful feature with Unite's vertical_preview option, giving much more context around if the window is high enough. Example:

swapfile trouble when two denites in same workdir

Problems summary

denite creates swapfile, which creates problems when starting denite in new instance.

Start nvim and run :Denite file_rec. Leave it like that
Start another nvim (in the same workdir) and run :Denite file_rec, now swap file message. After making any choice

neovim.api.nvim.NvimError: b'Vim(new):E325: ATTENTION'

and denite fails

Expected

Denite is nofile buffer. No swapfile is created. Can run denite in two instances the same time in the same workdir without problems.

tabopen action not working

Problems summary

Unable to open file in new tab. When I invoke denite with Denite -default-action=tabopen file_rec and hit <CR> on a line, nothing happens. If I enter normal mode and attempt to press t to do_action:tabopen, nothing happens.

If I invoke without the default-action, everything works as expected and denite opens the file in the current window.

Feature request: Python2 compatibility

Many of the plugins I use are python2-only. I have vim8 installed, but compiled without py3 support because py3 caused breakage. How hard would it be to provide py2 compatibility ? I could even contribute if this is a manpower issue.
Thanks !

how can i change default glob of matcher_ignore_globs

First, thank you for the great plugin. I try to change the default glob of matcher_ignore_globs by writing below in init.vim:

if dein#tap('denite.nvim')
  nnoremap <leader>gd :<C-u>Denite
  call denite#custom#source(
  \ 'file_rec', 'matchers', ['matcher_fuzzy', 'matcher_ignore_globs'])
  call denite#custom#filter('matcher_ignore_globs', 'ignore_globs',
        \ [
        \ '.git/', '.ropeproject/', '__pycache__/',
        \ 'venv/',
        \ 'images/',
        \ '*.min.*',
        \ 'img/', 'fonts/'])
endif

but it seems not work. how can i set my ignore_globs of matcher_ignore_globs for file_rec?

What's the difference between this and fzf

buffer source is slow

buffer source is really slow, wondering if it could be speeded up by caching the buffers when these are created.

vim-airline extension

Problems summary

Hi there!

So I'm looking to create a new airline extension for denite, based on the extension for unite.vim.

https://github.com/vim-airline/vim-airline/blob/master/autoload/airline/extensions/unite.vim

But it seems there are a few missing APIs that are required .

Mostly:

unite_force_overwrite_statusline for denite
a get_status_string() function
a get_context() function.

I would like to help out where I can, but would like to get your thoughts on what the best approach would be for adding such features.

"Denite grep", quote required?

Warning: I will close the issue without the minimal init.vim and the reproduce ways.

Problems summary

In Denite grep, Using search word separated space, error has occured in process.py

test.txt contents is

Dark powered for Nvim
Dark powered for Vim8

and I run Denite grep , entered dark powerd.

I logged the arguments passed to subprocess.Popen in Process#__init__.
and I run it on IPython repl.

So, following error.

In [9]: command2
Out[9]: ['grep', '-inH', '-r', '--', 'dark', 'powered', '.']

In [10]: subprocess.Popen(command2)
Out[10]: grep: powered: No such file or directory
./test.txt:1:Dark powered for Nvim
./test.txt:2:Dark powered for Vim8
<subprocess.Popen at 0x10f811048>

use only dark, ignored powered.

If I enterd 'dard powered', Arguments passed to subprocess.Popen is ['grep', '-inH', '-r', '--', 'dark powered', '.']

In [4]: command
Out[4]: ['grep', '-inH', '-r', '--', 'dark powered', '.']

In [5]: subprocess.Popen(command)
./test.txt:1:Dark powered for Nvim
./test.txt:2:Dark powered for Vim8
Out[5]: <subprocess.Popen at 0x10e639d30>

It seems good.

Expected

Input patterns should be quoted automatically(?)

"Denite buffer" order

Unite buffer enumerates previous buffer as first candidate, and current buffer as last candidate.
I hope so in Denite buffer

so, I workaround by these changes.

Is there any way to fix this problem?

Denite is awesome, but file_rec doesn't work on Windows.
I checked file_rec.py, it just returns nothing when using Windows. Is windows support planned?

[feature request] cursor movement in cmdline

I just create a chart plugin, here is the picture;

it support move cursor by <left> and <right>;
the main viml code of this feature is

    call s:buildPromot()

            if nr = 9
                 " mean you type `<enter>` then do something with the str
            elseif nr = "\<Right>"
                 let s:promot_l = s:promot_l . s:promot_c
                 let s:promot_c = matchstr(s:promot_r, '^.')
                 let s:promot_r = substitute(s:promot_r, '^.', '', 'g') 
            elseif nr = "\<Left>"
                if s:promot_l !=# ''

                      let s:promot_l = substitute(s:promot_l, '.$', '', 'g')
                endif
           endif

I do not use python, so I can not send the PR, I am not sure denite use the same func to build cmdline.

File paths relative to the project root

The search results in Denite file_rec show absolute paths. How can we make it shorter so that the file paths are relative to the project root? By project root, I meant the directory in which vim is opened.

RFC: Ctrl+n/Ctrl+p or Up/Down keys conflict with command-line history behaviour

I'm wondering to improve the denite.nvim prompt by coping a corresponding codes from prompt.nvim (To be honest, I would like to rely rather than copy while prompt.nvim is under development but I thought you feel copy is better because of #23).

Once prompt.nvim is forked into denite.nvim, the denite.nvim prompt would have the following features

Caret movement by <Left> and <Right>
Delete character before/under the caret (e.g. <Backspace> / <Delete>)
Paste text from register after the caret (e.g. <C-r>+)
Use a candidate of command-line history (e.g. <C-p>)
Use a matched candidate of command-line history (e.g. <Up>)
Custom key mappings (e.g. Use <C-f> to move the caret left)

However, currently denite.nvim uses <C-n>/<C-p> or <Up>/<Down> to select candidate.
This behaviour conflicts with Vim's default command-line behaviour :-(

So I would like to propose to change the default mapping for selecting candidate to <C-t>/<C-g> like Vim's incsearch behaviour (doc).
As long as users can custom mappings, I feel that default mappings should follow Vim flavour.
What do you think about this?

Example

You can custom key mappings by something like

let g:prompt#custom_mapping = [
      \ ["<C-D>", "<Del>"],
      \ ["<C-A>", "<Home>"],
      \ ["<C-E>", "<End>"],
      \ ["<C-F>", "<Left>"],
      \ ["<C-B>", "<Right>"],
      \ ["<C-P>", "<C-T>", 1],  " 1 means 'noremap'
      \ ["<C-N>", "<C-G>", 1],
      \]

The reproduce ways from neovim starting (Required!)

vim -u test_vimrc a.txt b.txt c.txt
:vsp b.txt
Ctr-W l (move a.txt window)
:Denite buffer and select c.txt

[feature request] list denite-options in wildmenu only when hyphen is typed

By default :Denite <TAB> shows in the wildmenu all possible options and the sources at the end of the wildmenu

I would prefer following behavior:

:Denite <TAB> shows only all possible sources in the wildmenu.

If I type :Denite -<TAB>, the wildmenu should show the options.

What do you think?

need help

hi, this is not a issue. i need help info that migrate from unite to denite.
i look into the help file before i open this issue.
1.how can i ignore some file types in file_rec and grep source?
2.does file_rec and grep accept a variable as directory parameter? for instance:
i write a function GetGitDir() and it return the gitdir in .vimrc, i hope to use it as
:Denite file_rec:`GetGitDir()` in vimrc.
3.about the denite#custom#var and denite#custom#source?what 's the difference? i saw both of them has a source like grep or file_rec parameter.
