rooter.nvim changes the working directory to the project root when you open a file. It is inspired by vim-rooter.
This plugin also provides telescope and picker.nvim extensions to fuzzy find recently opened projects.

- Automatic project root detection on
BufEnter/VimEnter - Re-detect root on
BufWritePost(e.g. after creating a new.git/) - Project history caching to disk for persistence across sessions
- Outermost vs nearest root directory support
- Flexible behavior for non-project files (
'','home', or'current') - Automatic logging via logger.nvim (optional dependency)
- Callback APIs for project switch events
- Command-line interface (
:Rooter) - Telescope integration
- Picker.nvim integration
using nvim-plug
require('plug').add({
{
'wsdjeg/rooter.nvim',
config = function()
require('rooter').setup({
root_patterns = { '.git/' },
})
end,
}
})require('rooter').setup({
root_patterns = { '.git/' },
outermost = true,
enable_cache = true,
project_non_root = '',
command = 'lcd',
})| Option | Type | Default | Description |
|---|---|---|---|
root_patterns |
table<string> |
{ '.git/' } |
Patterns to identify project root. Directories end with /, files do not. |
outermost |
boolean |
true |
When true, find the outermost matching directory. When false, find the nearest (innermost). |
enable_cache |
boolean |
true |
Persist project history to stdpath('data')/nvim-rooter.json for cross-session persistence. |
project_non_root |
string |
'' |
Behavior for files outside any project: '' = keep cwd, 'home' = switch to $HOME, 'current' = switch to file's directory. |
command |
string |
'lcd' |
Vim command used to change directory: 'cd', 'tcd', or 'lcd'. |
require('rooter').setup({
root_patterns = { '.git/', '.hg/', 'Cargo.toml', 'go.mod', 'package.json' },
outermost = false, -- find nearest root
command = 'tcd', -- use tab-local cd
})Once setup() is called, rooter.nvim automatically changes the working directory
whenever you open a file or switch buffers. You can also use the commands and APIs below.
This plugin provides a user command :Rooter:
| Command | Description |
|---|---|
:Rooter |
Manually trigger root detection for current buffer. |
:Rooter clear |
Clear all cached projects. |
:Rooter kill project1 project2 |
Delete all buffers belonging to the specified project(s). |
Requires telescope.nvim.
:Telescope project
Lists all cached projects sorted by last opened time. Press <CR> to open a
project in a new tab.
Requires picker.nvim.
:Picker project
Key bindings for picker project:
| Key binding | Description |
|---|---|
<CR> |
Open project in a new tab (default action) |
<C-f> |
Browse project files |
<C-d> |
Delete project from history |
<C-s> |
Search text in project, requires flygrep.nvim |
To run custom logic when the project changes, register a callback with
rooter.reg_callback:
-- Update code-runner config based on project's .clang file
local c_runner = {
exe = 'gcc',
targetopt = '-o',
usestdin = true,
opt = { '-std=c11', '-xc', '-' },
}
require('code-runner').setup({
runners = {
c = { c_runner, '#TEMP#' },
},
})
local function update_clang_flag()
if vim.fn.filereadable('.clang') == 1 then
local flags = vim.fn.readfile('.clang')
local opt = { '-std=c11' }
for _, v in ipairs(flags) do
table.insert(opt, v)
end
table.insert(opt, '-xc')
table.insert(opt, '-')
c_runner.opt = opt
end
end
require('rooter').reg_callback(update_clang_flag, 'update clang flags')The callback receives no arguments. It is called via pcall so errors won't
crash the root detection flow. You can also pass a Vimscript function name as
a string.
| Function | Description |
|---|---|
setup(opt) |
Initialize rooter.nvim with config options and set up autocmds. |
current_root() |
Detect and switch to the project root for the current buffer. Returns the root path. |
current_name() |
Returns the current project name (from b:rooter_project_name). |
list() |
Open the project picker (Picker.nvim or Telescope, whichever is available). |
open(project_path) |
Open a project by its path in a new tab. |
clear() |
Clear all cached projects and write empty cache to disk. |
kill_project(name) |
Delete all buffers belonging to the named project. |
reg_callback(func, desc?) |
Register a callback function (or Vimscript function name) to run on project switch. desc is an optional description for logging. |
get_project_history() |
Returns the table of all cached projects. |
Install logger.nvim as a dependency. Logging is automatically enabled when logger.nvim is available — no extra config needed.
