romgrk / barbar.nvim Goto Github PK

Description

When not using icons, the space (reserved to the icon?) is not colored,
thus is still set to the default color, black in this case.

To Reproduce

init.vim:

set runtimepath^=~/.local/share/nvim/plugged/barbar.nvim

set termguicolors

let bufferline = {}
let bufferline.icons = v:false

hi BufferCurrent guibg=red
hi BufferInactive guibg=gold

Open with nvim -u init.vim Foo Bar.

When the number of buffers is enough to exceed the width of the window, you can get into situations where you current buffer is either partially or all the way off screen. It'd be ideal if the line would "scroll" so that the currently selected buffer is always fully on screen.

example of it being partially off screen:

(To this day, I have this problem on my own tabline impl)

Ideas:

• Use WarningMsg foreground for modified buffers

I switched to this plugin from vim-airline's buffer tabs because this looks so much sexier. However, something I miss from airline's buffer tabs is the little indicator in the topright corner which shows up when you have multiple vim tabs open, indicating with a number which is the current one, for instance "tab 1/2" as shown in my screenshot. I would love if this were added to this plugin.

Forgot to port them during the lua rewrite.

The bar's background color also changes, from when there are only buffers (and no tabs open):

Is that intended?

Making a new issue for this as requested. I currently have my eyes on this range as a potential problem area (although I don't really know for sure):

if layout.tabpages_width > 0 then
    result = result .. '%=%#BufferTabpages# ' .. tostring(current_tabpage) .. '/' .. tostring(total_tabpages) .. ' '
end

-- vim.g.layout = {
--   scroll = state.scroll,
--   max_scroll = max_scroll,
--   layout = layout,
--   needed_width = needed_width,
--   accumulated_width = accumulated_width,
-- }

result = result .. hl('TabLineFill')

I think this because when you change the %=% to something like %foo%, the bar comes back at the end:

I'm admittedly unfamiliar with tabline syntax though.

Don't know if it is just a problem with my config or not. I am on NVIM v0.5.0-812-gd17e50879.
Here is what happens

Description

If option bufferline.icons is not defined than plugin throws exception.

PS. I've spent a half hour for finding this issue =)

Hi. Thanks for the nice plugin. Would it be possible to hide barbar if only one buffer is open?

I've found some issues, which airline#extensions#tabline doesn't have:

Dot directory

• Run nvim .
• Tab name is .
• Go to any directory
• Tab name has changed

nobuflisted buffers

• Run nvim . (opens netrw)
• Neovim starts with one tab "No Name" and after a few milliseconds the name is changed to .

• Run nvim . (opens netrw)
• Go to any directory
• New tab is opened (with name of directory) and after a few milliseconds it closed

• Run nvim .
• Open new tab (:tabnew or :tabe filename)
• Go to previous tab (<C-PageUp>)
• netrw tab doesn't have active flag

• :e filename
• :Explore (sets nobuflisted)
• Tab "filename" doesn't have an active flag
• Press C-O (go back)
• Tab "filename" have an active flag

• :e dir1 (opens tab with no name)
• :e dir2 (previous tab name has changed)
• :e dir3 (previous tab name has changed)

• :e .
• :e . (tab has closed)

No tabs

• Install vim-startify plugin
• Run nvim
• New tab "No Name" is opened and after a few milliseconds it closed
• Black tabline with vertical line on the left (maybe it's a UI bug)

I was trying the :BufferPick feature as shown in your README:

Let's say our buffer is highlight.vim and we press h. In my nvim, this returns the input focus to the buffer (good) but doesn't clear the red letters from the bar. We made a choice (or mistake) to stay on the current buffer, so the state should return to normal.

nvim: 0.5.0-dev (current)

If this cannot be reproduced on your side, I'll glady add more information of course.

Hi, fresh install and I'm seeing a ton of repeats of the following:

E121: Undefined variable: g:icons
E15: Invalid expression: status == 'Inactive' ? g:icons.bufferline_separator_inactive : g:icons.bufferline_separator_active

Am I missing a config someplace?

When too many tabs are open for all of them to fit on screen the current tab can end up hiding off screen. It would be nice if in this situation the plugin scrolled all tabs so that the current one becomes visible.

I am really enjoying this plugin, however the only thing that seems to be missing, is being able to see the number next to the title of the tab.

In most situations, I have under 9 tabs, so being able to see the number allows me to use a :BufferGoto keybind easily and swiftly. Here is an example from my previous configuration without barbar.nvim:

This option could also be off by default, if this not something that other people want.

Instead of picking the next unassigned letter when a buffer is opened, we could instead try to assign it the first letter of it's name, then something else if that letter is already taken.

Implement commands that allow to order tabs by dirctory, or by language, which is how I order them when I work.

Description

Question marks are shown instead of icons in tab bar.

To Reproduce

This is on MacOS. I tried the plugin on a linux machine too and also there I did not get icons.

I tried running :lua require'nvim-web-devicons'.has_loaded(). This did not give any output.

For instance, when running nvim foo bar baz in the shell, the buffer tabs order, i.e. baz, bar, foo.

Description

I tried configuring barbar. When I open vim I see the following error:

E121: Undefined variable: g:bufferline

Minimal vimrc

set runtimepath^=~/.config/nvim/pack/plugins/opt/barbar
let g:bufferline.icons = v:false

To Reproduce

1. Open vim
2. See the error

If I set let g:bufferline.icons = v:false manually after vim is open the setting is correctly recognized and applied.

I think it will be more intuitive for people.

For instance when you close a buffer but three are open and then the editor just closes.

I am not sure if this is an intended feature, but if I open vim and then open a second buffer like so:

and then switch to the [buffer 0] tab using the :BufferPick command, [buffer 3] disappears and, I guess "collapses" into [buffer 1]. This is somewhat understandable as if vim senses that I am switching from an empty buffer, it just deletes it. But the problem is that now when trying to quit out, I have to type :q twice in order to exit from both buffers.

The weirder thing is that if I have more than two empty buffers open, say four for example, it only appears to collapse some of the buffers when switching.

I just found your Plugin and I really, really like it so far. In my current project I always have a split terminal at the button of my buffers (using neoterm) so my question is:
is it possible to set an option to exclude terminal buffers from the list?

Currently it looks like this:

Thanks in advance,

Would be great to have mouse support. Sure, (n)vim users use the keyboard. However, for me personally, I tend to use a lot the mouse when I know I'm going to just be reading code for a long time, without writing/editing. It would be great to be able to traverse tabs/buffers using the mouse in this situation.

Thanks for considering!

I've noticed the plugin flashes really fast when starting up the plugin Startify. Not then end of the world but if you have an easy fix for that I would appreciate it.

I'm enjoying this plugin a lot. Thank you for developing it! However, in order to maintain my moral superiority over my colleges, I use the Colemak layout rather than qwerty. Would you be willing to add an option to set the key order of bufferline.semantic_letters for those of us using alternate layouts?

Trying the plugin since it looks really cool but cannot get it working. When opening nvim or a buffer the tabline still shows the default look. I need to manually call silent! call bufferline#update() to show it (silent is used to hide:

Error detected while processing function <SNR>26_check_modified[3]..bufferline#update[1]..bufferline#render[52]..<SNR>26_get_icon:
line    5:
E121: Undefined variable: g:lua_tree_icons
E15: Invalid expression: g:lua_tree_icons.default

)

Once the tabline shows properly, it does not get updated when I move to a different buffer. I need to manually call bufferline#update() again.

Any ideas what can be wrong?

Im using latest neovim (HEAD) and have all requirements installed (+kyazdani42/nvim-tree.lua)

Hey,
thanks for this cool plugin. Looks pretty neat!

It would be very cool to have a way to scroll between all open tabs without switching to any buffers. It could be mapped to <S-ScrollWheelDown> and <S-ScrollWheelUp> for instance, or just some key. Looking through the code I saw this plugin already has some logic for setting scroll so it shouldn't be too complicated to expose it to users

TBD:

• Make it deterministic (should give the same output not matter the order of the buffers)
• Make names as short as possible

I was wondering if the icons were supposed to be colored.

It would be nice if it had support for powerline rounded separators between buffers.

I tried to disable the close buttons using g:bufferline.closable but I'm getting the error E121: Undefined variable: g:bufferline when Neovim launches. What am I doing wrong? The following is my minimal config:

Description

Greetings!

I am experimenting with barbar.nvim some now, and am encountering an issue when attempting to open to close buffers.

If I load multiple buffers at initialization (e.g. nvim *.py), no error is encountered and I can switch between buffers fine.

As soon as I attempt to close a buffer, however, or create a new one, I run into issues.

To Reproduce

Attempting to open a new buffer (e.g. :e tmp):

Error detected while processing function bufferline#update[1]..bufferline#render:
line    5:
E5101: Cannot convert given lua type
E5108: Error executing lua error converting argument 2

Attempting to call :BufferClose:

Error detected while processing function bufferline#update[1]..bufferline#render:
line    5:
E5101: Cannot convert given lua type
E5108: Error executing lua error converting argument 5

Similar errors arise when attempting to call other functions that result in new buffers being created such as :checkhealth or :PlugUpdate.

init.vim: khughitt/dotfiles/nvim/init.nvim

barbar.nvim section:

# barbar.nvim loaded via vim-plug
nnoremap <silent>    <leader>bd :BufferClose<CR>
nnoremap <silent>    <S-Tab> :BufferPrevious<CR>
nnoremap <silent>    <Tab> :BufferNext<CR>
nnoremap <silent>    <S-left> :BufferPrevious<CR>
nnoremap <silent>    <S-right> :BufferNext<CR>

I've tried disabling other plugins that seemed like they might conflict with barbar.nvim (airline, denite, etc.), but so far, no luck.

Creating a clean config and going through plugins one-by-one or batch-by-batch could work, but would likely take a lot of time, so I thought I would post here first in case you have any insights into what the problem might be?
