# tabby.nvim
A declarative, highly configurable, and neovim style tabline plugin. Use your
nvim tabs as a workspace multiplexer!![](https://raw.githubusercontent.com/wiki/nanozuki/tabby.nvim/assets/banner.png)
## Compatibility and Versions
Compatibility has always been a key consideration for `tabby.nvim`. Since its
inception during the Neovim 0.5 era, the landscape of plugin management and
semantic versioning has not been widely adopted; hence, we have made every
effort to maintain backward compatibility with each release.However, since then, numerous Neovim APIs have been added, altered, or
deprecated, and the design philosophy of `tabby.nvim` has also gone through
several iterations. Maintaining complete backward compatibility has become
increasingly challenging. Therefore, starting from this version, `tabby.nvim`
will adhere to semantic versioning. Within the same major version, no breaking
changes will be introduced.At next major version, v3, `tabby.nvim` will cleaner all deprecated apis and
remove all vimscript.## Concept
**A line for the vim tab page, not for buffers**
A tab page in vim holds one or more windows(not buffers). You can easily switch
between tab pages to have several collections of windows to work on different
things.Tabline can help you use multiple tabs. Meanwhile, the bufferline is simply an
array of opened files. As a result, Bufferline limits the power of vim,
especially when editing a large workspace with many opened files.For example, you are writing a backend service:
```
- Tab1: nvim-tree, controller/user.go, entity/user.go
- Tab2: nvim-tree, pkg/cache.go, redis/client.go
- Tab3: Terminal
- Tab4: Neogit.nvim
```**Declarative, highly configurable**
Tabby provides a declarative way to configure tabline. You can set the tabline
to whatever neovim natively supports and complete the config with any lua code.
At least that's the goal of tabby. And also, the tabby provides some presets to
quick start or as your example.## Playground
Want to try your new config with no fear? Want to reproduct/debug a problem?
Want to contribute? Use the playground!1. Clone this repository, or open the directory your plugin manager installed
tabby.nvim.
2. Put your config in 'playground/config.lua'
3. Execute `make play`, into a temporary neovim to check the config.
4. Use `make clear-play` to clean the change.## Install
Use your favorite plugin manager or script to installing 'nanozuki/tabby.com'.
If you use `lazy.nvim`, you can refer the following example:```lua
{
'nanozuki/tabby.nvim',
-- event = 'VimEnter', -- if you want lazy load, see below
dependencies = 'nvim-tree/nvim-web-devicons',
config = function()
-- configs...
end,
}
```You don't need lazy load since 'tabby.nvim' is not slow. If you really want,
you can use `VimEnter` or `VeryLazy` or anything else you like. Some of them
(like `VeryLazy`) will make the raw tabline render first, and re-render to
tabby's line quickly.## Setup
### Tabline option
At default, neovim only display tabline when there are at least two tab pages.
If you want always display tabline:```lua
vim.o.showtabline = 2
```### Save and restore in session
You can save and restore tab layout and tab names in session, by adding word
`tabpages`(for layout) and `globals`(for tab names) to `vim.opt.sessionoptions`.
This is a valid `sessionoptions`:```lua
vim.opt.sessionoptions = 'curdir,folds,globals,help,tabpages,terminal,winsize'
```### Setup tabby.nvim
And you can setup your own tabline like this (check [Customize](#Customize) for
more details):```lua
local theme = {
fill = 'TabLineFill',
-- Also you can do this: fill = { fg='#f2e9de', bg='#907aa9', style='italic' }
head = 'TabLine',
current_tab = 'TabLineSel',
tab = 'TabLine',
win = 'TabLine',
tail = 'TabLine',
}
require('tabby').setup({
line = function(line)
return {
{
{ ' ', hl = theme.head },
line.sep('', theme.head, theme.fill),
},
line.tabs().foreach(function(tab)
local hl = tab.is_current() and theme.current_tab or theme.tab
return {
line.sep('', hl, theme.fill),
tab.is_current() and '' or '',
tab.number(),
tab.name(),
tab.close_btn(''),
line.sep('', hl, theme.fill),
hl = hl,
margin = ' ',
}
end),
line.spacer(),
line.wins_in_tab(line.api.get_current_tab()).foreach(function(win)
return {
line.sep('', theme.win, theme.fill),
win.is_current() and '' or '',
win.buf_name(),
line.sep('', theme.win, theme.fill),
hl = theme.win,
margin = ' ',
}
end),
{
line.sep('', theme.tail, theme.fill),
{ ' ', hl = theme.tail },
},
hl = theme.fill,
}
end,
-- option = {}, -- setup modules' option,
})
```> In recent versions, we use `require('tabby.tabline').set(fn, opt?)` to set up
> the tabline. You can continue to use this.### Examples and Gallery
These are some awesome examples shared by tabby.nvim users! Also welcome to
share your own![Discussions: show and tell](https://github.com/nanozuki/tabby.nvim/discussions/categories/show-and-tell)
### Presets
If you want to quick start? That's fine, you can [Use Preset Configs](#Use-Presets). And you can use theme of [lualine](https://github.com/nvim-lualine/lualine.nvim) in presets.
### Commands
- `Tabby rename_tab `: Rename tab. Use name in line by `tab.name()`
(ref: [Tab](#Tab)). Config fallback name by [Line-Option](#Line-Option)
- `Tabby pick_window`: Open a selector to pick window in tabpages.### Key mapping example
Tabby uses native nvim tab, so you can directly use nvim tab operation. Maybe
you want to map some operation. For example:```lua
vim.api.nvim_set_keymap("n", "ta", ":$tabnew", { noremap = true })
vim.api.nvim_set_keymap("n", "tc", ":tabclose", { noremap = true })
vim.api.nvim_set_keymap("n", "to", ":tabonly", { noremap = true })
vim.api.nvim_set_keymap("n", "tn", ":tabn", { noremap = true })
vim.api.nvim_set_keymap("n", "tp", ":tabp", { noremap = true })
-- move current tab to previous position
vim.api.nvim_set_keymap("n", "tmp", ":-tabmove", { noremap = true })
-- move current tab to next position
vim.api.nvim_set_keymap("n", "tmn", ":+tabmove", { noremap = true })
```And in fact, vim has some built-in keymapping, it's better to read `:help tabline`. Here are some useful mappings:
```vimdoc
gt *i_CTRL-* *i_*
Go to the next tab page. Wraps around from the last to the
first one.
{count}gt Go to tab page {count}. The first tab page has number one.
g Go to previous (last accessed) tab page.
gT Go to the previous tab page. Wraps around from the first one
to the last one.
```The `{count}` is the number displayed in presets.
## Customize
Customize tabby with `require('tabby').setup(opts)`:
```vimdoc
tabline.set({opts}) *tabby.setup()*
Set tabline renderer functionParameters: ~
• {opts} Options dict:
• line (funtion) required: renderer function, receive a line
(|tabby.object.line|), return a node (|tabby.object.node|).
• option (|LineOption|) optional: renderer option.
```All you need is to provide a render function, that use the variable `line`
(ref: [Line](#Line)) to complete tabline node (ref: [Node](#Node)). The `line`
variable gathered all features the tabby provided. And you can use `opt` (ref:
[Line Option](#Line Option)) to customize some behaviors.The render function will be called every time the nvim redraws tabline. You can
use any valid neovim lua code to contracture the Node in this function. For
example, if you want display current directory in tabline, you can do like
this:```lua
require('tabby').setup({
line = function(line)
local cwd = ' ' .. vim.fn.fnamemodify(vim.fn.getcwd(), ':t') .. ' '
return {
{
{ cwd, hl = theme.head },
line.sep('', theme.head, theme.line),
},
".....",
}
end,
option = {},
})

tab_name = {
name_fallback = function(tabid)
return "fallback name"
end
},
buf_name = {
mode = "'unique'|'relative'|'tail'|'shorten'",
}
}
```#### tab_name
Use command `Tabby rename_tab ` to rename tab. Use `tab.name()` (ref:
[Tab](#Tab)) to add in your config. If no name provided, `tab.name()` will
display fallback name. The default fallback name is current window's buffer name.You can change the fallback by provide a function in
`opt.tab_name.name_fallback`.#### buf_name
There are four mode of buffer name. If current directory is "~/project" and
there are three buffers:- "~/project/a_repo/api/user.py"
- "~/project/b_repo/api/user.py"

```### Node
Node is the rendered unit for tabby. Node is a recursive structure. It can be:
- A string: "nvim"
- A Number: 12
- A table containing a Node or an array of Node, with an optional property 'hl'
to set highlight. Example:```lua
-- node 1
{
"tab1", 100
hl = "TabLineSel"
}
-- node 2
{
"text 1"
{
"text 2",
hl = "Info",
},
"text3",
hl = "Fill",
}
```### Highlight
There are two ways to declare a highlight:
- Use the name of neovim highlight group: "TabLineSel"
- Define "background", "foreground" and "style" in lua table:
`{ fg = "#000000", bg = "#ffffff" style = "bold" } `.
The "style" can be:
- bold
- underline
- underlineline, double underline
- undercurl, curly underline
- underdot, dotted underline
- underdash, dashed underline
- strikethrough
- italic### API
```vimdoc
api.get_tabs() *tabby.api.get_tabs()*
Get all tab idsapi.get_tab_wins({tabid}) *tabby.api.get_tab_wins()*
Get an winid array in specified tabid.api.get_current_tab() *tabby.api.get_current_tab()*
Get current tab's id.api.get_tab_current_win({tabid}) *tabby.api.get_tab_current_win()*
Get tab's current win's id.api.get_tab_number({tabid}) *tabby.api.get_tab_number()*
Get tab's number.api.get_wins() *tabby.api.get_wins()*
Get all windows, except floating window.api.get_win_tab({winid}) *tabby.api.get_win_tab()*
Get tab id of specified window.api.is_float_win({winid}) *tabby.api.is_float_win()*
Return true if this window is floating.api.is_not_float_win({winid}) *tabby.api.is_not_float_win()*
Return true if this window is not floating.
```## Use Presets
You can use presets for a quick start. The preset config uses nerdfont,
and you should use a nerdfont-patched font to display that correctly.To use preset, you can use `setup({ preset , option? })`, for example:
```lua
require('tabby').setup({
preset = 'active_wins_at_tail',
option = {
theme = {
fill = 'TabLineFill', -- tabline background
head = 'TabLine', -- head element highlight
current_tab = 'TabLineSel', -- current tab label highlight
tab = 'TabLine', -- other tab label highlight
win = 'TabLine', -- window highlight
tail = 'TabLine', -- tail element highlight
},
nerdfont = true, -- whether use nerdfont
lualine_theme = nil, -- lualine theme name
tab_name = {
name_fallback = function(tabid)
return tabid
end,
},
buf_name = {
mode = "'unique'|'relative'|'tail'|'shorten'",
},
},
})
```The `{opt}` is an optional parameter, including all option in
[Line Option](#Line-Option). And has some extending options:- {theme}, the example shows the default value.
- {nerdfont}, whether use nerdfont, default is true.
- {lualine_theme}, use lualine theme to make `theme`. if `theme` is set, this option will be ignored. default is empty.There are five `{name}` of presets:
- active_wins_at_tail
![](https://raw.githubusercontent.com/wiki/nanozuki/tabby.nvim/assets/active_wins_at_tail.png)
Put all windows' labels in active tabpage at end of whold tabline.
- active_wins_at_end
Put all windows' labels in active tabpage after all tags label. In-active
tabpage's window won't display.
![](https://raw.githubusercontent.com/wiki/nanozuki/tabby.nvim/assets/tabby-default-1.png)
- tab_with_top_win
Each tab lab with a top window label followed. The `top window` is the focus
window when you enter a tabpage.
![](https://raw.githubusercontent.com/wiki/nanozuki/tabby.nvim/assets/tab_with_top_win.png)
- active_tab_with_wins
Active tabpage's windows' labels is displayed after the active tabpage's label.
![](https://raw.githubusercontent.com/wiki/nanozuki/tabby.nvim/assets/active_tab_with_wins.png)
- tab_only
No windows label, only tab. and use focus window to name tab
