Chaning icons from mini.icons to something else

[greed-d]

If I'm right then the picker uses mini.icons for programming language icons, well I did find the icons field for picker, I can't seem to get how to override the mini.icons to something else?

You can override Snacks.util.icon like this:

https://github.com/folke/snacks.nvim/blob/main/lua/snacks/util/init.lua#L120-L154

{
  "folke/snacks.nvim",
  priority = 1000,
  lazy = false,
  config = function(_, opts)
    require('snacks').setup(opts)
    Snacks.util.icon = function(name, cat, opts)
      -- Copy and modify from https://github.com/folke/snacks.nvim/blob/main/lua/snacks/util/init.lua#L120-L154
      -- Example with `mini.icons`:
      return require("mini.icons").get(cat or "file", name)
    end
  end,
}

I cleared neovims cache and the icons seem to be working on Snacks.picker.buffers() albeit inconsistently. So I did some investigating, the behavior is very strange and the rabbit hole goes deep.

To show you whats happening I will use the following files:

• test.py
• test.md
• test.lua
• test.txt

Test Case 1: All Buffers Active

This is what the icons are supposed to look like for the file types using nvim-web-devicons and this is the starting point for my demonstration in Snacks.picker.buffers():

Test Case 2: .txt Icon Fallback

If I trigger ["<c-x>"] = { "bufdelete", mode = { "n", "i" } }, to delete the top .py file buffer, the bottom .txt buffer turns to the fallback icon:

Test Case 3: .md Icon Switch

I if then delete the middle .lua buffer from the remaining buffers, the top .md buffer turns to a different icon:

I’ve encountered many more weird inconsistencies.

Perhaps issue #1936 is related? I saw you comment on that one, but I’m not very familiar with Lua or regex, so I’m unsure how to move forward on my own.

I will take a closer look. I remember that dpetka2001 pointed out something was off, particularly with the buffers picker.

[drowning-cat]

The issue is here:

snacks.nvim/lua/snacks/picker/format.lua

Lines 52 to 54 in bc0630e

	if item.buf and vim.api.nvim_buf_is_loaded(item.buf) then
	name = vim.bo[item.buf].filetype
	cat = "filetype"

If the buffer is loaded, the formatter prefers the filetype icon over the file icon. However, this shouldn't be the case for the buffers picker, even though it contains a buf field.

[drowning-cat]

It can be patched with:

opts = {
  picker = {
    sources = {
      buffers = {
        format = function(item, picker)
          local ret = Snacks.picker.format.buffer(vim.tbl_extend('force', item, { buf = false }), picker)
          ret[1][1] = tostring(item.buf)
          return ret
        end,
