[Colorschemes] How to remove unwanted item from the list of colorschemes.

[iamxiaojianzheng]

I want to keep only a few I want and not show them all.

[dpetka2001]

I used to have a function as can be seen here in my dots. Recently, I tried this in a testing configuration

local builtins = {}

for name, _ in vim.fs.dir("$VIMRUNTIME/colors/") do
  if name:match("*.txt") then
    break
  else
    name = name:match(".*%.lua$") or name:match(".*%.vim$")
    table.insert(builtins, name)
  end
end

vim.opt.wildignore:append(builtins)

in my /lua/config/options.lua and I think I'll also update my personal configuration to this. Both of them do the same thing, ignoring the default Neovim colorschemes.

[iamxiaojianzheng]

Based on your code, I implemented this idea that you are really cool.

local get_colorsheme = function()
  local builtins = {}

  for name, _ in vim.fs.dir("$VIMRUNTIME/colors/") do
    if name:match("*.txt") then
      break
    else
      name = name:match("(.*).lua$") or name:match("(.*).vim$")
      table.insert(builtins, name)
    end
  end
  local target = vim.fn.getcompletion

  ---@diagnostic disable-next-line: duplicate-set-field
  vim.fn.getcompletion = function()
    return vim.tbl_filter(function(color)
      return not vim.tbl_contains(builtins, color)
      ---@diagnostic disable-next-line: param-type-mismatch
    end, target("", "color"))
  end

  LazyVim.pick("colorschemes")()
  vim.fn.getcompletion = target
end

return {
  {
    "ellisonleao/gruvbox.nvim",
    keys = {
      { "<leader>uC", get_colorsheme, desc = "Colorscheme with preview" },
    },
  },
  { "sainnhe/gruvbox-material" },
  {
    "rebelot/kanagawa.nvim",
    keys = {
      { "<leader>uC", get_colorsheme, desc = "Colorscheme with preview" },
    },
  },
  {
    "folke/tokyonight.nvim",
    lazy = false,
    priority = 1000,
    opts = {},
    keys = {
      { "<leader>uC", get_colorsheme, desc = "Colorscheme with preview" },
    },
  },
  -- disabled default keymap
  {
    "ibhagwan/fzf-lua",
    event = "VeryLazy",
    keys = {
      { "<leader>uC", false },
    },
  },
  -- Configure LazyVim to load gruvbox
  {
    "LazyVim/LazyVim",
    opts = {
      colorscheme = "gruvbox",
    },
  },
}

I would like to ask an additional question about lazyvim's reload function.

If I modify and save plugin/xxx.lua, I will be prompted to reload this configuration in the upper right corner.

But the actual effect is not using the latest configuration, so what does this reload really do?

[dpetka2001]

The reload notification that you're seeing is the detection from lazy.nvim when you change some configuration file. So, if you remove a plugin spec, then in Lazy UI you'll see the change that the plugin is ready to be removed.

It doesn't reload your Neovim configuration. There's an option in lazy.nvim about reloading a plugin spec but Folke himself said it doesn't work 100%. So, your best bet is to still restart Neovim for the latest changes in your configuration to take effect.

If you don't like that notification you can disable it. In your /lua/config/lazy.lua

change_detection = {
    -- automatically check for config file changes and reload the ui
    enabled = true,
    notify = true, -- get a notification when changes are found
  },

Change notify = false if you don't want to see these notifications.

@dpetka2001

I have another question to ask you.

I found that my stylua.toml didn't seem to work, such as the 'column_width = 120' configuration item, even if the lua code line is less than 120 characters, will be formatted.

[dpetka2001]

I'm not familiar with this. Sorry.

[iamxiaojianzheng]

I know the reason, LazyVim source code is through this to control the prohibition of formatting

-- stylua: ignore

Recently, telescope added the ignore_builtins option:

nvim-telescope/telescope.nvim#3155

It's now as simple as Telescope colorscheme ignore_builtins=true

[dpetka2001]

I've switched to fzf-lua instead of Telescope. I just have this

local builtins = {}

for name, _ in vim.fs.dir("$VIMRUNTIME/colors/") do
  if name:match("*.txt") then
    break
  else
    name = name:match(".*%.lua$") or name:match(".*%.vim$")
    table.insert(builtins, name)
  end
end

vim.opt.wildignore:append(builtins)

in my options.lua instead of a function that gets passed into telescope keymap. You also don't have to override vim.fn.completion temporarily 😛

[dpetka2001]

I don't get completions about searches from those files with this, but it's something I'm willing to live with since I'm not interested in them.

[abeldekat]

That's a nice solution!
As an alternative, I think you could also add the ignored builtins to the FzfLua colorscheme command, using opt ignore_patterns.
That way, you don't need to "wildignore".

[dpetka2001]

Yes, I know. I just prefer it this way since it's independent of which filepicker you use (of course with LazyVim.pick you can easily incorporate it regardless of which filepicker) and you don't have to pass anything to whatever function. Like I said I just don't care about these files at all, so I'm personally willing to not get any results about them anywhere.
