Extensible UI for Neovim notifications and LSP progress messages.
Demo setup
Note that this demo may not always reflect the exact behavior of the latest release.
This screen recording was taken as I opened a Rust file I'm working on,
triggering rust-analyzer
to send me some LSP progress messages.
As those messages are ongoing, I trigger some notifications with the following:
local fidget = require("fidget")
vim.keymap.set("n", "A", function()
fidget.notify("This is from fidget.notify().")
end)
vim.keymap.set("n", "B", function()
fidget.notify("This is also from fidget.notify().", vim.log.levels.WARN)
end)
vim.keymap.set("n", "C", function()
fidget.notify("fidget.notify() supports annotations...", nil, { annote = "MY NOTE", key = "foobar" })
end)
vim.keymap.set("n", "D", function()
fidget.notify(nil, vim.log.levels.ERROR, { annote = "bottom text", key = "foobar" })
fidget.notify("... and overwriting notifications.", vim.log.levels.WARN, { annote = "YOUR AD HERE" })
end)
(I use normal mode keymaps to avoid going into ex mode, which would pause Fidget rendering and make the demo look glitchy...)

Fidget is an unintrusive window in the corner of your editor that manages its own lifetime. Its goals are:
- to provide a UI for Neovim's
$/progress
handler - to provide a configurable
vim.notify()
backend - to support basic ASCII animations (Fidget spinners!) to indicate signs of life
- to be easy to configure, sane to maintain, and fun to hack on
There's only so much information one can stash into the status line. Besides, who doesn't love a little bit of terminal eye candy, as a treat?
Fidget requires Neovim v0.9.0 .
If you would like to see progress notifications, you must have configured Neovim
with an LSP server that uses the $/progress
handler.
For an up-to-date list of LSP servers this plugin is known to work with, see
this Wiki page.
Install this plugin using your favorite plugin manager.
See the documentation for setup()
options.
{
"j-hui/fidget.nvim",
opts = {
-- options
},
}
Plug 'j-hui/fidget.nvim'
" Make sure the plugin is installed using :PlugInstall. Then, somewhere after plug#end():
lua <<EOF
require("fidget").setup {
-- options
}

:Rocks install fidget.nvim
Fidget is actively developed on the main
branch, and may occasionally undergo
breaking changes.
If you would like to ensure configuration/API stability, you can pin your tag to one of the release tags.
For instance, using Lazy:
{
"j-hui/fidget.nvim",
tag = "v1.0.0", -- Make sure to update this to something recent!
opts = {
-- options
},
}
Fidget can be configured by passing a table of options to the setup()
.
Available options are shown below:
{
-- Options related to LSP progress subsystem
progress = {
poll_rate = 0, -- How and when to poll for progress messages
suppress_on_insert = false, -- Suppress new messages while in insert mode

ignore_empty_message = false, -- Ignore new tasks that don't contain a message
clear_on_detach = -- Clear notification group when LSP server detaches
function(client_id)
local client = vim.lsp.get_client_by_id(client_id)
return client and client.name or nil
end,
notification_group = -- How to get a progress message's notification group key
function(msg) return msg.lsp_client.name end,
ignore = {}, -- List of LSP servers to ignore

Fidget has a Lua API, with documentation generated from source code. You are encouraged to hack around with that.
Fidget exposes some of its Lua API functions through :Fidget
sub-commands
(e.g., :Fidget clear
), which support shell-like arguments and completion.
These sub-commands are documented below.
Clear active notifications
Arguments
Positional arguments:
{group_key}
:(any)
group to clear
Clear notifications history
Arguments
Flags:
--before {seconds}
:(number)
filter history for items updated at least this long ago--group_key {group_key}
:(any)
clear history by group key--include_active {true|false}
:(boolean)
whether to clear items that have not been removed (default: true)--include_removed {true|false}
:(boolean)

Rather than defining its own highlights, Fidget's default configuration uses built-in highlight groups that are typically overridden by custom Vim color schemes. With any luck, these will look reasonable when rendered, but the visual outcome will really depend on what your color scheme decided to do with those highlight groups.
You can override these highlight groups (e.g., icon_style
) using the :h fidget-options
shown above.
rcarriga/nvim-notify is first and
foremost a vim.notify()
backend, and it also supports
LSP progress notifications
(with the integration seems to have been packaged up in
mrded/nvim-lsp-notify).
vigoux/notifier.nvim is
a vim.notify()
backend that comes with first-class LSP notification support.
neoclide/coc.nvim provides a nice LSP progress UI in the status line, which first inspired my desire to have this feature for nvim-lsp.
arkav/lualine-lsp-progress was the original inspiration for Fidget, and funnels LSP progress messages into nvim-lualine/lualine.nvim. I once borrowed some of its code (though much of that code has since been rewritten).
nvim-lua/lsp-status.nvim also supports showing progress text, though it requires some configuration to integrate that into their status line.
Most of the Fidget spinner patterns were adapted from the npm package sindresorhus/cli-spinners.
