How to set up keyboard shortcuts for snacks plugin?

[Mrid22]

Hi im trying to configure a kyboard shortcut to open the snacks explorer, in neovim that would be: keys = {{ "", function() Snacks.picker.pick("files") end, {} }}. In nixvim i'm trying to do config.keymaps = [{key = "; action = "snacks.explorer()"; mode = ["n"];}]; but it's not working. Thank you!

Yes, this is probably because snacks has not been loaded in the local scope. Also, you need to set action to be a raw lua string. Otherwise, the content will be embedded in a lua string.
This would give:

keymaps = [
  {
    key = "<YOUR_KEY>";
    action.__raw = "require('snacks').explorer";  # No trailing `()` as we don't want to call the function here
    mode = "n";
  }
];

A useful thing to do when experimenting with such things is to use the vendored nixvim-print-init command which shows you the generated init.lua.

What does nixvim-print-init shows? Maybe this is actually a lua table and not a proper function.

here's the output:

1 │ -- Nixvim's internal module table
2 │ -- Can be used to share code throughout init.lua
3 │ local _M = {}
4 │
5 │ -- Set up options {{{
6 │ do
7 │ local nixvim_options = { termguicolors = true }
8 │
9 │ for k, v in pairs(nixvim_options) do
10 │ vim.opt[k] = v
11 │ end
12 │ end
13 │ -- }}}
14 │
15 │ require("tokyonight").setup({ transparent = true })
16 │
17 │ vim.cmd([[colorscheme tokyonight
18 │ ]])
19 │ require("snacks").setup({ explorer = { enable = true }, indent = { enable = true } })
20 │
21 │ require("lualine").setup({})
22 │
23 │ -- Set up keybinds {{{
24 │ do
25 │ local __nixvim_binds = { { action = require("snacks").explorer, key = "e", mode = "n" } }
26 │ for i, map in ipairs(__nixvim_binds) do
27 │ vim.keymap.set(map.mode, map.key, map.action, map.options)
28 │ end
29 │ end
30 │ -- }}}

uhh it syas that its not an editor command, but nixvim is applied and functional so idk why this isn't recognised as a command.

This is not a vim command, but a shell one. Just run it from your terminal.

As I said, require('snacks').explorer is maybe not a function, and actually, it isn't:

Maybe, what you want is require('snacks').explorer.open.

Thanks! actually the fix was function() Snacks.explorer() end which I probably should have figured out given that i've configured this in lua before. Sorry for wasting your time and thanks for all the help.

I'm happy that it works now!
