Firstly, this plugin is awesome. Something that has been missing for Vim for some time. So thank you.

When I use :Vista finder, I can only retrieve the buffer tags, like :BTags from FZF. How can I use :Vista finder to find symbols for the whole project, just like :Tags?

Tagbar has the :TagbarShowTag command, that opens the tag bar if it is not already open and selecting the tag that the cursor in the code buffer is currently under. Together with #30 this really helps to see the local structure of the code where you currently are.

Can Vista have a similar feature?

follow-up problems of #35 :

• how to take care of the custom ctags cmd.
• transform the short kind to the long, e.g., the long kind missing in hasktags.
• how to handle multiple filetypes share one type, e.g., cpp and cuda.
• the new ctags options may be unneccessary for the finder functionality, which can be replaced with the previous simpler one.

With a default executive of "vim-lsp" there is no cycle to "ctags" executive when opening the sidebar with ":Vista". It does perform this cycling correctly when using ":Vista finder".

This was identified under #33

AFAICT, it seems that the auto update is handled by this autocmd

    autocmd BufWritePost,BufReadPost,CursorHold * call
                \ s:AutoUpdate(fnamemodify(expand('<afile>'), ':p'))

Is it a feature or a bug?

Basically, ctags should be fast to genrate tags in the buffer, but it may be very slow to generate tags in a whole project. Some language server may need some time to give back the document symbols, especially when they are indexing. So, it would be better to show if these jobs are still running in the background, making me feel more responsive.

Describe the solution you'd like
A clear and concise description of what you want to happen.

• SetBusy(1) when starting the job.
• SetBusy(0) when the job stops.
• draw the spinner in the duration via a timer.

I realize that Vista normally won't be a mainly focused window, so this feature may not deserve the effort. I won't add it myself.

Hi,

Awesome project, thanks!

I use NeovimLanguageClient and want to use Vista!! with it:

nnoremap <Leader>e :Vista!! lcn<Return> 
nnoremap <Leader>f :Vista!! finder lcn<Return> 

But Im getting the following error:

[vista.vim] Invalid args. expected: Vista![!]

I guess I can make my own function to toggle the Vista window, but seems like Vista!! should work with other sources as well.

Thanks

Describe the bug
When hovering a symbol in the side view while having let g:vista_echo_cursor_strategy = 'floating_win' in config, the Airline statusline enters in an infinite reset loop, overloading one of my CPU cores.

Steps to reproduce

let g:vista_echo_cursor_strategy = 'floating_win'

2. :Vista
3. Hover any symbol

Expected behavior
No reset loop, normal Airline statusline.

Actual behavior
Statusline enters in a loop of setting and unsetting the Airline statusline.

Environment:

• OS: Debian GNU/Linux 9.7 (stretch)
• Vim/Neovim version:

NVIM v0.4.0-430-g8698830cb
Build type: RelWithDebInfo

• This plugin version: 5434531

vista开启悬浮窗支持后，只要把光标移动到标签之上，触发悬浮窗就会不断的出现该状况。弹出这两个映射命令。

这是fzf调用rg的映射

还有

请问这是什么原因

Tagbar supports universal/exuberant ctags.
See http://docs.ctags.io/en/latest/format.html#

There are several ways to show details of the tag under cursor when you are in the vista sidebar:

1. echo the information with highlight in cmd line.
2. popup a floating window to reveal the lines close to the target line that the tag is located.
3. scroll the source file to make the source line of the tag visible(#80).

It's distracting to enable all these strategies, so I plan to let the option g:vista_echo_cursor_strategy could only used to choose either one, or both, but not all of them. The current valid values for g:vista_echo_cursor_strategy:

• echo
• floating_win
• both

I have not figured it out what value for the third strategy, maybescroll?. Let me know if you have any ideas about this option.

vista fails with:

I'm using Vista with coc for editing Typescript in Neovim v0.3.4. When I press the slash button in the Vista window I get the following error:

Running :Vista finder in the same file works fine with no error. The slash behavior also works fine with JSON filetype (only other filetype I've tested).

I just have this one line in my init.vim:

let g:vista_default_executive = 'coc'

To display the current method/function your cursor is inside it is possible to add this to the vim configuration:

function! NearestMethodOrFunction() abort
  return get(b:, 'vista_nearest_method_or_function', '')
endfunction

set statusline+=%{NearestMethodOrFunction()}

However, this does not work unless you've opened up Vista with :Vista. So if you want this functionality but don't want the actual Vista pane open, you have to perform an extra action.

Describe the solution you'd like

A way to "silently trigger" Vista functionalities like this without having to open & close the pane.

Provide a function that is callable when you open a buffer, or maybe a configuration option to automatically do this when a file is opened ?

Describe alternatives you've considered

Currently I'm just considering making a keybinding that opens and closes the pane.

This issue was created in relation to neoclide/coc.nvim#512 (comment)

Describe the bug
when function selected floating window seems to blink.

Environment:

• OS: 10.14.3 (18D109)
• Neovim version: v0.4.0-dev
• This plugin version: 3c222b3

Steps to reproduce given the above minimal vimrc
Open a file that contains method/function move your mouse to any function, floating window will show up and start blinking.

Expected behavior
floating window to pop up but not blink.

Describe the bug

I have set the g:vista_sidebar_width option to 60, but after the first time it shows the window, it then resets the width to its default value.

Environment:

• OS: Mac OS
• Vim/Neovim version: Neovim 0.3.4
• This plugin version: 5fef8e3

Minimal vimrc to reproduce

" Vista configuration
let g:vista_default_executive = 'coc'
let g:vista_close_on_jump = 1
let g:vista_blink  = [0, 0]
let g:vista_sidebar_width = 60
let g:vista_finder_alternative_executives = ['coc']
let g:vista#renderer#enable_icon = 0
map <C-m> :Vista coc<CR>

How to reproduce

1. Press <C-m> to open Vista's view.
2. Press q to close it.
3. Press <C-m> again.

First render

Next renders

Currently vista.vim only echoes the information of the symbol under cursor in the cmdline, it would be nice to also support show them via neovim's floating window.

Describe the bug
After the last update, when I hit enter on a symbol in Vista's view to jump to the function in the current buffer, before closing the Vista's view it displays the following error:

Steps to reproduce given the above info

1. Open Vista using :Vista.
2. Go to a symbol and press enter.

Expected behavior
Vista's windows should close and the cursor should be positioned on the function.

Actual behavior
Before closing Vista's window, it shows the error described previously.

I am using neovim 0.4.0 Nvim development (prerelease) build. from here :https://github.com/neovim/neovim/releases/download/nightly/nvim-macos.tar.gz
And using LanguageClient-neovim plugin.Using default setting for python.

Then I map two key like this:
nnoremap <F2> :Vista lcn<CR>
nnoremap <F3> :Vista finder lcn<CR>

After setting those, I start a empty neovim with nothing opened,then press F2, and F3, neovim is hang,not response at all.

Global Variables:
let g:vista#executives = ['coc', 'ctags', 'lcn', 'vim_lsp']
let g:vista_echo_cursor_strategy = 'floating_win'
let g:vista_icon_indent = ['▸ ', '']

Vista lists the tags grouped by type, unlike Tagbar that groups them by structure and nests them. Consider the following screenshot, with the code on the left, Tagbar in the middle, and Vista on the right:

The Tagbar style gives you a clear overview of the code's structure, while Vista is quite a mess to look at (especially in my example, where different methods have the same name).

Even if the tags were just ordered by their location in the file instead of being grouped by tag type the result would be much nicer. Nesting by indentation is of course a nice bonus, and so is the parameter list (that can when there is overloading)

As the title described, I want get a option to show Vista's buffer in current window, rather than open a new window - sidebar.

Because I want to integrate Vista with NERDTree, let them on the same side. If there is no thus option, I can not do it.

Please support if you have free time, Thanks ! 😄

[vista.vim]Fail to run ctags: ctags --format=2 --excmd=pattern --fields=nksSaf --extras= --file-scope=yes --sort=no --append=no --language-force=javascript --javascript-kinds=cpC
fvgm -f- /var/folders/_y/d89_j12d2xq_cnlh8v6btwpw0000gn/T/nvimDqvMz2/18.js
[vista.vim] Empty data for finder

Previously, ctags has some fixed fields PF which are unused by vista.vim, which could be disabled since universal-ctags/ctags#2080, reducing some overhead when using JSON format output.

How can I get this plugin working with fzf?

I didn't find anything relevant in the README.md.

Thanks.

At each update, the cursor jumps back to the initial point where Vista was invoked.

Describe the bug
When I have a class inside a class, and have things inside that inner class, Vista doesn't work.

Vista info

    Current FileType: text
Avaliable Executives: ['ctags', 'lcn']
    Global Variables:
    let g:vista#executives = ['coc', 'ctags', 'lcn', 'vim_lsp']
    let g:vista_ctags_renderer = 'default'
    let g:vista_fzf_preview = ['right:50%']
    let g:vista_stay_on_open = 0

Steps to reproduce given the above info

1. Create this file:

   class Foo:
       class Bar:
           def baz(self):
               pass

2. Run :Vista ctags

Expected behavior
Vista's sidebar should open

Actual behavior
A blank sidebar and this error message:

Hi, is it possible to sort the symbols alphabetically? Currently they appear according to the order they were declared, but it could be useful to be able to sort them.

Describe the bug
Vista spams undefined variable tagfield when in certain files. Specifically, I've been able to replicate the problem in the source code of some vim plugins. I have isolated the problem to this line. I could be missing something, but as far as I can tell, tagfield will always be undefined in that line. Changing tagfield to a:tagfields[0], which I think is the intention, completely removes the problem. I can make a PR if that would be helpful.

Environment:

• OS: Ubuntu 18.10
• Vim/Neovim version: NVIM v0.4.0-dev, Build type: RelWithDebInfo
• This plugin version: 3da62ec
• It may be relevant that I am using coc.nvim with coc-neco

Vista info

Current FileType: vim
Avaliable Executives: ['coc', 'ctags']
Global Variables:
let g:vista#executives = ['coc', 'ctags', 'lcn', 'vim_lsp']
let g:vista_fzf_preview = ['right:50%']

Steps to reproduce given the above info
I think this bug is pretty straight forward, but if a minimal init.vim/vimrc which reproduces the problem would be helpful let me know.

Describe the bug
cursor jumps to wrong buffer when after buffer is open

Steps to reproduce

1. open a source code and open Vista.
2. open help
3. move to vista window and
4. select anything for cursor to jump onto source code

Expected behavior
the cursor should be on the right buffer and the right line.

Actual behavior
but the cursor is at another buffer (help buffer in this case)

Screenshot or gif (if possible)

Vista generates tags of left buffer, but jumps to help buffer

Environment:

• OS: Mac OS, 10.14.2
• Vim/Neovim version: nvim 0.3.4
• This plugin version: e121c68

When using a preview window with fzf, fzf should preview the file the ctags came from.

Describe the bug
With let g:vista_sidebar_position = 'vertical topleft', vista window should always open on the left side. However it only opens on the left side for the first time.

Environment:

• OS: macOS 10.14.4
• Vim/Neovim version: NVIM v0.4.0-dev
• This plugin version: 3797c49

Vista info

Steps to reproduce given the above info

1. Open vista window
2. Use q to quit vista window
3. Use :Vista or :Vista!! to open vista window again
4. See if the vista window is open on the left

Expected behavior
The vista window should always open on the left.

Actual behavior
The vista window is open on the left only for the first time.

Describe the bug
I get the following error whenever cursor is hovering symbol types (e.g. Method, Function, Field, Variable, Class):

Error detected while processing function vista#cursor#ShowDetail:
line   11:
E46: Cannot change read-only variable "count"

Steps to reproduce

1. Open a source file that works under LSP
2. Call :Vista
3. Move cursor over symbol types

Expected behavior
Error shouldn't happen.

Actual behavior
The following error pops up:

Error detected while processing function vista#cursor#ShowDetail:
line   11:
E46: Cannot change read-only variable "count"

Environment:

• OS: Debian 9.7 (Stretch)
• Vim/Neovim version:

VIM - Vi IMproved 8.1 (2018 May 18, compiled Mar  6 2019 09:15:43)
Included patches: 1-996

• This plugin version: a5d77a5b061fc22030cfb3700eaed99ed19abe40

We could make vista.vim like the screenshot above via the unicode symbols for the vanity:(. In order to achieve that, you'll have to install some special fonts, e.g., nerd fonts, even change your terminal emulator as not every terminal emulator could render these symbols properly to my knowledge.

Feel free to comment in this issue if you have any ideas.
