Diagnostics and Git component update

[idr4n]

I have a diagnostics component similar to the one in the cookbook. However, I noticed that despite having update = { "DiagnosticChanged", "BufEnter" } , diagnostics only get updated once I start moving the cursor.

At the moment, I added an autocommand in my config instead to get around this:

vim.api.nvim_create_autocmd("DiagnosticChanged", {
  group = vim.api.nvim_create_augroup("Status_Diagnostics", { clear = true }),
  callback = vim.schedule_wrap(function()
    vim.cmd("redrawstatus")
    vim.cmd("redrawtabline")
  end),
})

This works fine for me but I just want to understand why simply adding update = { "DiagnosticChanged", "BufEnter" } does not work as expected. Most likely I'm missing something.

Something similar happens in the gitdiff component with update = "GitSignsUpdate". Instead, I had to add this autocommand as mentioned in the gitsigns documentation:

vim.api.nvim_create_autocmd("User", {
  group = vim.api.nvim_create_augroup("Status_GitUpdate", { clear = true }),
  pattern = "GitSignsUpdate",
  callback = vim.schedule_wrap(function()
    vim.cmd("redrawstatus")
  end),
})

Note that this didn't work for me either:

{
...
  update = { 
    "User",
    pattern = "GitSignsUpdate",
    callback = vim.schedule_wrap(function()
      vim.cmd("redrawstatus")
    end),
  }
}

Thanks in advance!

Are you on nightly? I think it might be nvim issue actually as both components updated immediately in the past but I have seen this behaviour for a while now as well.

Yes, I am on nightly, actually.

I was annoyed enough to bisect this today. The behavior was introduced in neovim/neovim@fe11079.

Just noting this here in case anyone wants to open an issue before I get to it.

minimal init.lua:

local plugins = {
  gitsigns = 'lewis6991/gitsigns.nvim',
  heirline = 'rebelot/heirline.nvim',
}

local plugin_path = '/tmp/nvim-bisect/plugins/'
(vim.uv or vim.loop).fs_mkdir(plugin_path, 0755)

for name, path in pairs(plugins) do
  local fullpath = plugin_path .. name
  if not (vim.uv or vim.loop).fs_stat(fullpath) then
    -- stylua: ignore
    vim.fn.system({ 'git', 'clone', '--depth=1', '--filter=tree:0', 'https://github.com/' .. path, fullpath, })
  end
  vim.opt.rtp:append(fullpath)
end

require('gitsigns').setup()

local function git_diff_component(s, icon)
  return {
    condition = function(self)
      return self.status_dict[s] ~= nil and self.status_dict[s] > 0
    end,
    provider = function(self)
      return ' ' .. icon .. self.status_dict[s]
    end,
  }
end

require('heirline').setup({
  statusline = {
    condition = require('heirline.conditions').is_git_repo,
    init = function(self)
      self.status_dict = vim.b.gitsigns_status_dict
    end,
    update = { 'User', patterh = 'GitSignsUpdate' },
    { -- branch
      provider = function(self)
        return self.status_dict.head
      end,
    },
    git_diff_component('added', '+'),
    git_diff_component('changed', '~'),
    git_diff_component('removed', '-'),
  },
})
