-- DO NOT change the paths and don't remove the colorscheme

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name

require('lazy').setup(plugins, {

vim.cmd.colorscheme('tokyonight')

vim.api.nvim_create_augroup('NoiceTest', {})
vim.api.nvim_create_autocmd('ModeChanged', {
  callback = function()
    local mode = vim.api.nvim_get_mode().mode
    print('mode changed: ' .. mode)
  end,
  group = 'NoiceTest'
})

I looked into this, and unfortunately this is not possible to fix.

When the cmdline is displayed, I need to make sure the cursor is always visible. I do this using vim.cmd([[noautocmd silent! normal! ze]]).

It seems that that sets the mode to normal internally, so when exiting the cmdline, the ModeChanged is not triggered.

@folke Hmm ok. Is it possible to raise a custom event like NoiceCmdLineLeave when leaving command-line mode that I can subscribe to?

[folke]

I was able to work-around this issue by not using a normal command to horizontally align the cursor. ModeChanged triggers as expected now

Thank you! Works great!
