This is a Neovim plugin/library for generating statusline components from the built-in LSP client.


  • 2021/03/13: Some users report success using the Google "Noto Emoji" font for status_symbol and indicator_hint.
  • 2020/11/19: Please note that the default diagnostics symbols require Font Awesome or a Nerd Font. You may also change the diagnostics symbols as shown in the configuration section.
  • 2020/11/13: Due to this PR, you must update to the latest Neovim master to avoid errors with the old diagnostics API. See issue #19 for more information.
  • 2020/05/25: There has been a minor breaking change to the API: extension_callbacks is now named extensions. There have also been a number of additions and improvements; see the below (specifically Configuration and Example Use) for details.

Show the current containing function (like b:coc_current_function): Statusline showing current function and no errors

Easily access diagnostic counts: Statusline showing some error indicators

Show progress messages from servers: Statusline showing progress messages from a server


You will need a version of Neovim that includes the built-in LSP client (right now, that means nightly). Use your preferred package/plugin manager. With vim-packager, this looks like:

call packager#add('nvim-lua/lsp-status.nvim')


The plugin provides several utilities:

update_current_function() -- Set/reset the b:lsp_current_function variable
-- Shows the current function, method, class, struct, interface, enum, module, or namespace
diagnostics() -- Return a table with all diagnostic counts for the current buffer
messages() -- Return a table listing progress and other status messages for display
register_progress() -- Register the provided handler for progress messages
register_client() -- Register a client for messages
-- Integrate misc. LS protocol extensions into the messages framework
-- Each extension table contains a set of handlers and a setup() function 
-- returning said handlers
extensions = { clangd, pyls_ms }
-- Set up a client for use with lsp-status. Calls register_client() and sets up 
-- buffer autocommands
config(config_vals) -- Configure lsp-status
-- Table of client capabilities extended to signal support for progress messages
status() -- One example out-of-the-box statusline component (as shown in the images above)

Protocol Extensions

lsp-status.nvim supports messaging-related protocol extensions offered by clangd and Microsoft's Python language server (python/setStatusBarMessage, python/beginProgress, python/reportProgress, and python/endProgress). To use these extensions, register the handlers provided in the extensions table (the keys for the handlers are the relevant LSP method name).

Note: For clangd, you must also set init_options = { clangdFileStatus = true }.

New: You can also call lsp_status.extensions.<server name>.setup() to return the full set of handlers, as shown below.


You can configure lsp-status.nvim using the config function, which takes a table of configuration values. The following configuration options are supported:

  • kind_labels: An optional map from LSP symbol kinds to label symbols. Used to decorate the current function name. Default: {}
  • select_symbol: An optional handler of the form function(cursor_pos, document_symbol) that should return true if document_symbol (a DocumentSymbol) should be accepted as the symbol currently containing the cursor.

For example, the sumneko lua server sends valueRange (which is not specified in the protocol) to give the range for a function's start and end. To respect valueRange, you can use the following configuration:

lsp_status.config {
  select_symbol = function(cursor_pos, symbol)
    if symbol.valueRange then
      local value_range = {
        ["start"] = {
          character = 0,
          line = vim.fn.byte2line(symbol.valueRange[1])
        ["end"] = {
          character = 0,
          line = vim.fn.byte2line(symbol.valueRange[2])

      return require("lsp-status.util").in_range(cursor_pos, value_range)
  • current_function: Boolean, true if the current function should be updated and displayed in the default statusline component.
  • show_filename: Boolean, true if the filename should be displayed in the progress text.
  • indicator_*-group: strings to show as diagnostic warnings. If you don't have Nerd/Awesome Fonts you can replace defaults with ASCII chars like this: ```
    • Put this somewhere near lsp_status.register_progress() lsp_status.config({ indicator_errors = 'E', indicator_warnings = 'W', indicator_info = 'i', indicator_hint = '?', indicator_ok = 'Ok', }) ```
  • indicator_separator: a string which goes between each diagnostic group symbol and its count. Defaults to whitespace.
  • component_separator: a string which goes between each "chunk" of the statusline component (i.e. different diagnostic groups, messages). Defaults to whitespace.
  • diagnostics: Boolean, true by default. If false, the default statusline component does not display LSP diagnostics.

Example Use

Here is an example configuration (also using nvim-lsp) showing how lsp-status can be integrated into one's statusline and other LSP configuration.

In any Lua file you load:

local lsp_status = require('lsp-status')
-- completion_customize_lsp_label as used in completion-nvim
-- Optional: customize the kind labels used in identifying the current function.
-- g:completion_customize_lsp_label is a dict mapping from LSP symbol kind 
-- to the string you want to display as a label
-- lsp_status.config { kind_labels = vim.g.completion_customize_lsp_label }

-- Register the progress handler

Before calling setup for each relevant LSP client:

-- Set default client capabilities plus window/workDoneProgress
config.capabilities = vim.tbl_extend('keep', config.capabilities or {}, lsp_status.capabilities)

In an on_attach function for each relevant LSP client:

-- Register client for messages and set up buffer autocommands to update 
-- the statusline and the current function.
-- NOTE: on_attach is called with the client object, which is the "client" parameter below

Specific client configuration (following nvim-lsp conventions):

clangd = {
  handlers = lsp_status.extensions.clangd.setup()
pyls_ms = {
  handlers = lsp_status.extensions.pyls_ms.setup()

LSP statusline segment

An example statusline segment is provided in lua/lsp-status/statusline. You are encouraged to read the source and develop your own statusline segment, but if you'd like something reasonable out-of-the-box, you can call lsp_status.status() somewhere in your statusline definition (make sure you have require'd the lsp-status module too!)

All together, now

Here's a complete example:

lua << END
local lsp_status = require('lsp-status')

local lspconfig = require('lspconfig')

-- Some arbitrary servers
  handlers = lsp_status.extensions.clangd.setup(),
  init_options = {
    clangdFileStatus = true
  on_attach = lsp_status.on_attach,
  capabilities = lsp_status.capabilities

  handlers = lsp_status.extensions.pyls_ms.setup(),
  settings = { python = { workspaceSymbols = { enabled = true }}},
  on_attach = lsp_status.on_attach,
  capabilities = lsp_status.capabilities

  on_attach = lsp_status.on_attach,
  capabilities = lsp_status.capabilities
  on_attach = lsp_status.on_attach,
  capabilities = lsp_status.capabilities

" Statusline
function! LspStatus() abort
  if luaeval('#vim.lsp.buf_get_clients() > 0')
    return luaeval("require('lsp-status').status()")

  return ''


This plugin is "complete" - it works in all the ways it was originally intended to, and it doesn't seem to break. That said, it hasn't been tested much, and I'm open to adding new features if others want them.

One thing that probably should be added is proper documentation of some sort. The code could also stand to be cleaned up.
