## Requirements
|
|
|
|
[neovim >=0.7.0](https://github.com/neovim/neovim/wiki/Installing-Neovim)
|
|
|
|
[nvim-web-devicons](https://github.com/kyazdani42/nvim-web-devicons) is optional and used to display file icons. It requires a [patched font](https://www.nerdfonts.com/).
|
|
|
|
## Install
|
|
|
|
Install with [vim-plug](https://github.com/junegunn/vim-plug):
|
|
|
|
```vim
|
|
Plug 'kyazdani42/nvim-web-devicons' " optional, for file icons
|
|
Plug 'kyazdani42/nvim-tree.lua'
|
|
```
|
|
|
|
or with [packer](https://github.com/wbthomason/packer.nvim):
|
|
|
|
```lua
|
|
use {
|
|
'kyazdani42/nvim-tree.lua',
|
|
requires = {
|
|
'kyazdani42/nvim-web-devicons', -- optional, for file icons
|
|
},
|
|
tag = 'nightly' -- optional, updated every week. (see issue #1193)
|
|
}
|
|
```
|
|
|
|
## Setup
|
|
|
|
Setup should be run in a lua file or in a lua heredoc [:help lua-heredoc](https://neovim.io/doc/user/lua.html) if using in a vim file.
|
|
|
|
```lua
|
|
-- examples for your init.lua
|
|
|
|
-- disable netrw at the very start of your init.lua (strongly advised)
|
|
vim.g.loaded = 1
|
|
vim.g.loaded_netrwPlugin = 1
|
|
|
|
-- empty setup using defaults
|
|
require("nvim-tree").setup()
|
|
|
|
-- OR setup with some options
|
|
require("nvim-tree").setup({
|
|
sort_by = "case_sensitive",
|
|
view = {
|
|
adaptive_size = true,
|
|
mappings = {
|
|
list = {
|
|
{ key = "u", action = "dir_up" },
|
|
},
|
|
},
|
|
},
|
|
renderer = {
|
|
group_empty = true,
|
|
},
|
|
filters = {
|
|
dotfiles = true,
|
|
},
|
|
})
|
|
```
|
|
|
|
For complete list of available configuration options see [:help nvim-tree-setup](doc/nvim-tree-lua.txt)
|
|
|
|
Each option is documented in `:help nvim-tree.OPTION_NAME`. Nested options can be accessed by appending `.`, for example [:help nvim-tree.view.mappings](doc/nvim-tree-lua.txt)
|
|
|
|
## Commands
|
|
|
|
See [:help nvim-tree-commands](doc/nvim-tree-lua.txt)
|
|
|
|
Basic commands:
|
|
|
|
`:NvimTreeToggle` Open or close the tree. Takes an optional path argument.
|
|
|
|
`:NvimTreeFocus` Open the tree if it is closed, and then focus on the tree.
|
|
|
|
`:NvimTreeFindFile` Move the cursor in the tree for the current buffer, opening folders if needed.
|
|
|
|
`:NvimTreeCollapse` Collapses the nvim-tree recursively.
|
|
|
|
## Api
|
|
|
|
nvim-tree exposes a public api; see [:help nvim-tree-api](doc/nvim-tree-lua.txt). This is a stable non breaking api.
|
|
|
|
## Mappings
|
|
|
|
nvim-tree comes with number of mappings; for default mappings please see [:help nvim-tree-default-mappings](doc/nvim-tree-lua.txt), for way of configuring mappings see [:help nvim-tree-mappings](doc/nvim-tree-lua.txt)
|
|
|
|
`g?` toggles help, showing all the mappings and their actions.
|
|
|
|
## Tips & tricks
|
|
|
|
* You can add a directory by adding a `/` at the end of the paths, entering multiple directories `BASE/foo/bar/baz` will add directory foo, then bar and add a file baz to it.
|
|
* You can update window options for the tree by setting `require"nvim-tree.view".View.winopts.MY_OPTION = MY_OPTION_VALUE`
|
|
* `toggle` has a second parameter which allows to toggle without focusing the explorer (`require"nvim-tree".toggle(false, true)`).
|
|
* You can allow nvim-tree to behave like vinegar, see [:help nvim-tree-vinegar](doc/nvim-tree-lua.txt)
|
|
* If you `:set nosplitright`, the files will open on the left side of the tree, placing the tree window in the right side of the file you opened.
|
|
* You can automatically close the tab/vim when nvim-tree is the last window in the tab: <https://github.com/kyazdani42/nvim-tree.lua/discussions/1115>. WARNING: this can catastrophically fail: <https://github.com/kyazdani42/nvim-tree.lua/issues/1368>. This will not be added to nvim-tree and the team will not provide support / assistance with this, due to complexities in vim event timings and side-effects.
|
|
* Hide the `.git` folder: `filters = { custom = { "^.git$" } }`. See [:help nvim-tree.filters.custom](doc/nvim-tree-lua.txt).
|
|
* To disable the display of icons see [:help nvim-tree.renderer.icons.show](doc/nvim-tree-lua.txt).
|
|
|
|
## Troubleshooting
|
|
|
|
## Diagnostic Logging
|
|
|
|
You may enable diagnostic logging to `$XDG_CACHE_HOME/nvim/nvim-tree.log`. See [:help nvim-tree.log](doc/nvim-tree-lua.txt)
|
|
|
|
## netrw Keeps Popping Up
|
|
|
|
Eagerly disable netrw. See [:help nvim-tree.disable_netrw](doc/nvim-tree-lua.txt)
|
|
|
|
## Performance Issues
|
|
|
|
If you are experiencing performance issues with nvim-tree.lua, you can enable profiling in the logs. It is advisable to enable git logging at the same time, as that can be a source of performance problems.
|
|
|
|
```lua
|
|
log = {
|
|
enable = true,
|
|
truncate = true,
|
|
types = {
|
|
git = true,
|
|
profile = true,
|
|
},
|
|
},
|
|
```
|
|
|
|
Please attach `$XDG_CACHE_HOME/nvim/nvim-tree.log` if you raise an issue.
|
|
|
|
*Performance Tips:*
|
|
|
|
* If you are using fish as an editor shell (which might be fixed in the future), try set `shell=/bin/bash` in your vim config. Alternatively, you can [prevent fish from loading interactive configuration in a non-interactive shell](https://github.com/kyazdani42/nvim-tree.lua/issues/549#issuecomment-1127394585).
|
|
|
|
* Try manually running the git command (see the logs) in your shell e.g. `git --no-optional-locks status --porcelain=v1 --ignored=matching -u`.
|
|
|
|
* Huge git repositories may timeout after the default `git.timeout` of 400ms. Try increasing that in your setup if you see `[git] job timed out` in the logs.
|
|
|
|
* Try temporarily disabling git integration by setting `git.enable = false` in your setup.

* Windows
|
|
* WSL
|
|
* msys
|
|
* powershell
|
