Performance

I use a 2-layer map to cache all lsp progress messages, thus transforming the O(N * M) time complexity calculation to almost O(1).

N is active lsp clients count, M is token count of each lsp client.

For more details, please see Design & Technics.

Requirement

• neovim ≥ 0.6.
• nerd fonts for icons.

Install

-- lua
return require('packer').startup(function(use)
  use {
    'linrongbin16/lsp-progress.nvim',
    config = function()
      require('lsp-progress').setup()
    end
  }
end)

-- lua
require("lazy").setup({
  {
    'linrongbin16/lsp-progress.nvim',
    config = function()
      require('lsp-progress').setup()
    end
  }
})

" vim
call plug#begin()

Plug 'linrongbin16/lsp-progress.nvim'

call plug#end()

lua require('lsp-progress').setup()

Usage

• LspProgressStatusUpdated: user event to notify new status, and trigger statusline refresh.

• require('lsp-progress').progress(opts): get lsp progress status, parameter opts is an optional lua table:

  require('lsp-progress').progress({
      format = ...,
      max_size = ...,
  })
  

  The fields are the same value passing to setup (see Configuration) to provide more dynamic abilities.

Integration

[!IMPORTANT]

Don't directly put require('lsp-progress').progress as lualine component or heirline's component provider, wrap it with a function to avoid the lazy dependency issue, see #131.

lualine.nvim

require("lualine").setup({
  sections = {
    -- Other Status Line components
    lualine_a = { ... },
    lualine_b = { ... },
    lualine_c = {
      -- invoke `progress` here.
      function()
        return require('lsp-progress').progress()
      end,
    },
    ...
  }
})

-- listen lsp-progress event and refresh lualine
vim.api.nvim_create_augroup("lualine_augroup", { clear = true })
vim.api.nvim_create_autocmd("User", {
  group = "lualine_augroup",
  pattern = "LspProgressStatusUpdated",
  callback = require("lualine").refresh,
})

heirline.nvim

local LspProgress = {
  provider = function()
    return require('lsp-progress').progress(),
  end,
  update = {
    'User',
    pattern = 'LspProgressStatusUpdated',
    callback = vim.schedule_wrap(function()
      vim.cmd('redrawstatus')
    end),
  }
}

local StatusLine = {
  -- Other StatusLine components
  { ... },

  -- Lsp progress status component here
  LspProgress,
}

require('heirline').setup({
  statusline = StatusLine
})

Configuration

To configure options, please use:

require('lsp-progress').setup(opts)

The opts is an optional lua table that overwrite the default options.

For complete options and defaults, please check defaults.lua.

For more advanced configurations, please see Advanced Configuration.

Alternatives

• lsp-status.nvim: Utility functions for getting diagnostic status and progress messages from LSP servers, for use in the Neovim statusline.
• fidget.nvim: Standalone UI for nvim-lsp progress.
