Delay in insert mode when leader key is space #15

Closed andvarfolomeev closed 1 year ago

andvarfolomeev commented 1 year ago

Plugin works great when leader key is not space. Otherwise, there is a delay.

In addition, I can say that when you press the space in insert mode, a window of which-key plugin appears. You can see it on the screenshot.

Following Which-key settings:

{
  'folke/which-key.nvim',
  enabled = true,
  keys = { '<leader>', '[', ']', 's' },
  dependencies = { 'wansmer/langmapper.nvim' },
  config = function()
    vim.o.timeout = true
    vim.o.timeoutlen = 300
    local lmu = require('langmapper.utils')
    local view = require('which-key.view')
    local execute = view.execute

    -- wrap `execute()` and translate sequence back
    view.execute = function(prefix_i, mode, buf)
      -- translate back to english characters
      prefix_i = lmu.translate_keycode(prefix_i, 'default', 'ru')
      execute(prefix_i, mode, buf)
    end

    -- if you want to see translated operators, text objects and motions in
    -- which-key prompt
    -- local presets = require('which-key.plugins.presets')
    -- presets.operators = lmu.trans_dict(presets.operators)
    -- presets.objects = lmu.trans_dict(presets.objects)
    -- presets.motions = lmu.trans_dict(presets.motions)
    -- etc

    require('which-key').setup()
  end,
}

Following langmapper settings:

{
  'Wansmer/langmapper.nvim',
  lazy = false,
  priority = 1, -- High priority is needed if you will use `autoremap()`
  config = function()
    require('langmapper').setup({})
  end,
}

I found recipe to avoid which-key, but delay is staying anyway

vim.api.nvim_create_autocmd('VimEnter', {
  desc = 'Translate global keybindings',
  callback = function()
    local ok, lm = pcall(require, 'langmapper')
    if ok then
      lm.automapping({ buffer = false })
    end
  end,
})
Wansmer commented 1 year ago

The delay in insert mode is not because of `langmapper', but because you have insert mode mappings that start with a space. (By the way, the leader key is not normally used for insert mode mappings and command line mode mappings).

Disable langmapper and check - the delay remains.

The which-key window probably appears in insert mode for the same reason.

I runned following commands without langmapper and with.

:redir! > vim_keys.txt
:imap
:redir END

As you can see Additional mappings in insert mode appears when langmapper and cmp is enabled. Later I will try to find reason

Wansmer commented 1 year ago

Unfortunately, I can't reproduce these bugs in insert mode. Also, when outputting imap I don't have <space>з, <space>ры and <space>рк registered by nvim-cmp.

Maybe you have some additional bindings in the cmp config?

If you find the problem, please, let me know.

andvarfolomeev commented 1 year ago

The reason of this behavior is my options of cmp plugin. In particular, It is mappings (<Tab>, S-<Tab>, <C-j>, <C-k>).

But I tried your cmp configuration and I get the same behavior. You can try to reproduce the bug. Add this mapping to your config. Note that the delay happens when leader is space and map in visual mode.
