What is the best way to define blink keybindings in a seperate file?

[Qwyntex]

Essentially I am trying to structure my neovim config in a way that sets all keybindings in a single file. Using vim.keymap.set(...) with the Blink commands does work, however it loses the nice functionality of fallback bindings that the plugin provides. How would I best configure the Keybindings so that I retain the fallback values?

Dumb

Why don't you just return an object from your file that contains all the blink.cmp keymaps? You can import this file from any part of your code.

If you don't want to deal with imports, you can also simply assign a global variable:

-- keymaps.lua

vim.g.blink_keymaps = {
  default = {
    preset = 'none',
    ['<Down>'] = { 'select_next', 'fallback' },
    ['<Up>'] = { 'select_prev', 'fallback' },
    -- ...
  },
  cmdline = {
    preset = 'none',
    -- ...
  },
}

-- blink.lua

return {
  'saghen/blink.cmp',
  -- please test on `main` if possible
  -- otherwise, remove this line and set `version = '*'`
  build = 'cargo build --release',
  opts = {
    keymap = vim.g.blink_keymaps.default,
    cmdline = {
      keymap = vim.g.blink_keymaps.cmdline,
    },
  },
}

Smart

The only potential issue is the loading order. In my opinion, your approach is quite tricky to implement.

• You can define all your keys as functions to avoid errors at startup (but if the plugin is not loaded before you use the keymap, you will still get an error).
• Or, you can define optional plugin specs that contain only the parts related to keymaps in a single file.
  lazy.nvim will automatically merge opts and keys fields.

-- plugins/keymaps.lua

local plugins = {}

-- stylua: ignore start
vim.keymap.set('n', '<F1>', function() vim.print 'Yay, general purpose keymap' end, {})
vim.keymap.set('n', '<F2>', function() vim.print 'Yay, general purpose keymap' end, {})
vim.keymap.set('n', '<F3>', function() vim.print 'Yay, general purpose keymap' end, {})
vim.keymap.set('n', '<F4>', function() vim.print 'Yay, general purpose keymap' end, {})
vim.keymap.set('n', '<F5>', function() vim.print 'Yay, general purpose keymap' end, {})
-- stylua: ignore end

table.insert(plugins, {
  'some-author/some-plugin',
  optional = true,
  keys = {
    -- ...
  },
})

table.insert(plugins, {
  'saghen/blink.cmp',
  optional = true,
  opts = {
    keymap = {
      preset = 'none',
      ['<Down>'] = { 'select_next', 'fallback' },
      ['<Up>'] = { 'select_prev', 'fallback' },
      -- ...
    },
    cmdline = {
      keymap = {
        preset = 'inherit',
        -- ...
      },
    },
  },
})

return plugins

thank you for your answer! I didn't know about the optional field in Lazy, I will be sure to use it in the future! I did end up with assigning a global variable because I have my keymap file outside of the plugin directory but I might rewrite the config to allow for your smarter solution.
Have a good day!
