How do I disable specific default keymap without overriding it?

[Demianeen]

I installed mini.move plugin and I wanted to set moving line left and right on H and L. I pass the plugin keymaps like this:

return {
  'echasnovski/mini.move',
  event = 'VeryLazy',
  keys = {
	-- trying to disable H and L keymaps here
    { '<s-h>', false },
    { '<s-l>', false },
  },
  opts = {
    mappings = {
      -- Move visual selection in Visual mode. Defaults are Alt (Meta) + hjkl.
      left = 'H',
      right = 'L',
      down = 'J',
      up = 'K',

      -- Move current line in Normal mode
      line_left = 'H',
      line_right = 'L',
      -- line_down = 'J',
      -- line_up = 'K',
    },
  },
}

But it doesn't help, I still have next, prev buffer keymaps set. How do you think I can disable these two keymaps?

You can only use keys section to disable keymaps that have been defined in the specific spec of a plugin. You can't use it to disable keymaps in general.

The process I usually follow to disable keymaps I don't like, is search through the repo to see where they are defined. For example if you search for <s-h>, you get these results. From there you see that the specific keymap is defined in 2 places (once in keymaps.lua for the default bprevious command and one more in ui.lua in the Bufferline spec).

So, to disable this keymap as you want, you would have to do it in 2 places as well. First in your own keymaps.lua and second in your custom spec for Bufferline in /lua/plugins/ directory.

here's how I do it to map lateral buffer movement to ALT-arrows, I hope it helps:

-- lua.config.keymaps
vim.keymap.del("n", "<S-h>")
vim.keymap.del("n", "<S-l>")
vim.keymap.set("n", "<M-Left>", "<cmd>bprevious<cr>", { desc = "Prev buffer" })
vim.keymap.set("n", "<M-Right>", "<cmd>bnext<cr>", { desc = "Next buffer" })

It does remove the keymap! Mini.move plugin is fired before lazyvim, so it never applies the keymap through.

In my keys only manually overriding in keys did help:

  keys = {
    {
      'H',
      function()
        require('mini.move').move_line('left')
      end,
    },
    {
      'L',
      function()
        require('mini.move').move_line('right')
      end,
    },
  },

@Demianeen
You could also just defer the setup of mini.move like so

  config = function(_, opts)
    vim.schedule(function()
      require("mini.move").setup(opts)
    end)
  end,

This would make it so, that the plugin gets loaded after the VeryLazy event (where keymaps.lua also gets loaded), thus your changes in opts.mappings would take effect.

Thanks @dpetka2001!
