Neovim task runner: JSON/YAML + toggleterm.nvim + telescope.nvim.
SessionLoadPost
(see Automatic task spawning)If you're looking for even more features I'd recommend trying overseer.nvim, as toggletasks.nvim probably won't be receiving new features in the nearest future. See https://github.com/jedrzejboczar/toggletasks.nvim/issues/16#issuecomment-1460742344 for more info.
The main idea behind this plugin is to be able to easily define build/setup commands for different projects, independently of your global editor configuration and to easily manage multiple background tasks.
This task management plugin is heavily inspired by plugins such as yabs.nvim and projectlaunch.nvim, as well as by VS Code Tasks. In fact, initially I planned to just extend projectlaunch.nvim but after some work I decided that it would require to much changes and it will be easier to write a separate plugin.
The main difference between toggletasks.nvim and other plugins is that toggletasks strictly integrates with existing solutions instead of writing things from scratch, i.e.
Other differences:
yabs.nvim
(currently, see blog post)
sources arbitrary Lua files; toggletasks uses only JSON which is much safer, though less powerfullyabs.nvim
has the concept of different outputs/runners; toggletasks always uses toggleterm.nvimprojectlaunch.nvim
has a dedicated UI for managing tasks and running groups of tasks; toggletasks uses
telescope to achieve similar results, allowing for multi-selection when spawning/selecting tasksprojectlaunch.nvim
has builtin runners for things like package.json/Makefile; this is not supported,
but maybe something to consider in the futureExample using packer.nvim:
use {
'jedrzejboczar/toggletasks.nvim',
requires = {
'nvim-lua/plenary.nvim',
'akinsho/toggleterm.nvim',
'nvim-telescope/telescope.nvim/',
},
-- To enable YAML config support
rocks = 'lyaml',
}
Run require('toggletasks').setup { ... }
in your init.lua
to configure this plugin.
Available options (with default values):
require('toggletasks').setup {
debug = false,
silent = false, -- don't show "info" messages
short_paths = true, -- display relative paths when possible
-- Paths (without extension) to task configuration files (relative to scanned directory)
-- All supported extensions will be tested, e.g. '.toggletasks.json', '.toggletasks.yaml'
search_paths = {
'toggletasks',
'.toggletasks',
'.nvim/toggletasks',
},
-- Directories to consider when searching for available tasks for current window
scan = {
global_cwd = true, -- vim.fn.getcwd(-1, -1)
tab_cwd = true, -- vim.fn.getcwd(-1, tab)
win_cwd = true, -- vim.fn.getcwd(win)
lsp_root = true, -- root_dir for first LSP available for the buffer
dirs = {}, -- explicit list of directories to search or function(win): dirs
rtp = false, -- scan directories in &runtimepath
rtp_ftplugin = false, -- scan in &rtp by filetype, e.g. ftplugin/c/toggletasks.json
},
tasks = {}, -- list of global tasks or function(win): tasks
-- this is basically the "Config format" defined using Lua tables
-- Language server priorities when selecting lsp_root (default is 0)
lsp_priorities = {
['null-ls'] = -10,
},
-- Defaults used when opening task's terminal (see Terminal:new() in toggleterm/terminal.lua)
toggleterm = {
close_on_exit = false,
hidden = true,
},
-- Configuration of telescope pickers
telescope = {
spawn = {
open_single = true, -- auto-open terminal window when spawning a single task
show_running = false, -- include already running tasks in picker candidates
-- Replaces default select_* actions to spawn task (and change toggleterm
-- direction for select horiz/vert/tab)
mappings = {
select_float = '<C-f>',
spawn_smart = '<C-a>', -- all if no entries selected, else use multi-select
spawn_all = '<M-a>', -- all visible entries
spawn_selected = nil, -- entries selected via multi-select (default <tab>)
},
},
-- Replaces default select_* actions to open task terminal (and change toggleterm
-- direction for select horiz/vert/tab)
select = {
mappings = {
select_float = '<C-f>',
open_smart = '<C-a>',
open_all = '<M-a>',
open_selected = nil,
kill_smart = '<C-q>',
kill_all = '<M-q>',
kill_selected = nil,
respawn_smart = '<C-s>',
respawn_all = '<M-s>',
respawn_selected = nil,
},
},
},
}
To load telescope pickers:
require('telescope').load_extension('toggletasks')
JSON configuration files are supported out-of-the-box via vim.json
module.
To enable YAML support, lyaml must be installed.
It is possible to use packer to install luarocks,
see Installation.
Available fields:
Field | Type | Description |
---|---|---|
name | string |
descriptive name for the task; pair (name, config_file) is used to uniquely identify a task (to kill existing if re-running or to filter out already running tasks in picker) |
id | string? |
Optional ID to use instead of the default pair (name, config_file) |
cmd | string |
Command to run |
cwd | string? |
Task working directory |
tags | table<string>? |
Tags used to group and filter tasks |
env | table<string, string>? |
Additional environmental variables passed to task |
clear_env | boolean? |
If set to true, only environmental variables from env will be passed to task |
close_on_exit | boolean? |
Auto-close terminal when task job exists (see toggleterm) |
hidden | boolean? |
Don't include this task in toggleterm tasks list (see toggleterm) |
count | number? |
Use given terminal number (see toggleterm) |
Variable expansion is supported using the syntax ${VAR}
(escaped by double $
, e.g. $${VAR}
will expand to ${VAR}
).
Environmental variables will be expanded in fields: cwd
, env
.
Additionally some special variables will be expanded in fields: cmd
, cwd
, env
.
Available special variables (snake case to minimize collisions with env):
${config_dir}
- location of the config file from which the task has been loaded${lsp_root}
- root_dir of a language server with highest priority for current buffer${win_cwd}
- Vim's window-local CWD${tab_cwd}
- Vim's tab-local CWD${global_cwd}
- Vim's global CWD${file}
- absolute path to the current buffer's file${cursor_line}
- cursor line of the current window${cursor_column}
- cursor column of the current windowVim filename-modifiers can be used inside the expansion
to modify the paths (by default all paths are absoulte),
e.g. ${file:t:r}
will transform /path/to/my-file.txt
into my-file
.

To use this plugin use the included telescope pickers:
Telescope toggletasks spawn
Telescope toggletasks select
Telescope toggletasks edit
These commands can be mapped to keybindings, e.g.
vim.keymap.set('n', '<space>ts', require('telescope').extensions.toggletasks.spawn,
{ desc = 'toggletasks: spawn' })
When selecting tasks to be spawned, one can just type #tagname
in the prompt to filter based on
tag. This is currently using the default string based matching but should work correctly in most cases.
To select all tasks that are currently visible press <C-a>
(default). To manually pick tasks use
<Tab>
/<S-Tab>
(telescope defaults) to perform multi-selection and press <C-a>
to spawn
selected tasks.
The following commands are available:
ToggleTasksInfo
- show current configurationToggleTasksConvert <from_file> <to_file>
- convert between configuration file formats (by file extension)It is possible to automatically launch tasks on autocmd events, e.g. to launch tasks on VimEnter
or SessionLoadPost
. This plugin exposes convenient function to achieve that.
For example, to launch all tasks marked with the auto
tag whenever a session is loaded use:
require('toggletasks').auto_spawn('SessionLoadPost', 'auto')
The first argument (event
) is the same as for vim.api.nvim_create_autocmd
.
For more fine grained auto_spawn
can take a function as the second argument:
require('toggletasks').auto_spawn({'VimEnter', 'SessionLoadPost'}, function(tasks)
return tasks
:with_tag('auto')
:not_tag('test')
:from_file('/some/path/toggletasks.json')
:name_matches('^/some/path.*$')
:filter(function(task)
return task.config.name ~= 'Hello world'
end)
end)
Sometimes it would be handy to share some common tasks between projects without the need to add config files
to all of these. It might also be handy to only include some tasks for certain filetypes.
There are several ways to achieve this in toggletasks.nvim
.
Put task config file somewhere under &runtimepath
(e.g. ~/.config/nvim/toggletasks.json
) and enable
option scan.rtp = true
. Note that this adds a lot of paths for scanning so in theory it might have
some performance impact (but probably not noticeable).
Put task config files for given filetypes under ftplugin/FILETYPE
in &runtimepath
and enable
the option scan.rtp_ftplugin = true
(should be much faster than 1.). For example, to add Lua-specific
tasks one could add a file ~/.config/nvim/ftplugin/lua/toggletasks.json
.
Use the setup option scan.dirs
as a function(win)
, and return the directories in which to search for task
config files. You can use the win
argument to get the filetype of current buffer, or to check any other
conditions, which can be used to select specific directories with task config files.
Define tasks directly in Lua in your setup function. Use a function to have even more control over which tasks should be included, e.g.
require('toggletasks').setup {
tasks = function(win)
local ft = vim.api.nvim_buf_get_option(vim.api.nvim_win_get_buf(win), 'filetype')
local tasks = {
{
name = 'Some task',
cmd = 'echo "hello"'
},
}
if ft == 'lua' then
-- table.insert(tasks, { name = ... })
end
return tasks
end,
-- ...
}
