How to show hidden files in AstroNvim's neo-tree

Introduction

Vim beginner's memo series.

This post introduces how to display hidden files in AstroNvim's neo-tree.

Main Content

In AstroNvim's default settings, dotfiles and gitignored files are hidden in neo-tree, which makes it a bit difficult to use.

I found a related issue here:

It seems that you can display hidden files by adding the following settings to user/init.lua:

return {
  plugins = {
    ["neo-tree"] = {
      hide_dotfiles = false,
    }
  }
}

However, even after adding this setting, hidden files were not displayed.
It turns out that you need to create neo-tree.lua in user/plugins and configure the settings there.

This time, I configured it as follows:

~/.config/nvim/lua/user/plugins/neo-tree.lua

return {
  "nvim-neo-tree/neo-tree.nvim",
  opts = {
    filesystem = {
      follow_current_file = { enabled = true },
      hijack_netrw_behavior = "open_current",
      use_libuv_file_watcher = true,
      filtered_items = {
        visible = false, -- Whether hidden by default
        show_hidden_count = true,
        hide_dotfiles = false, -- Whether to hide dotfiles
        hide_gitignored = false, -- Whether to hide gitignored files
        hide_by_name = {
          "node_modules",
          "thumbs.db",
        },
        never_show = {
          ".git",
          ".DS_Store",
          ".history",
        },
      },
    },
  },
}

Now, hidden files are displayed. Instead of setting hidden files to be visible by default, I handled it by excluding dotfiles and gitignored files from the hiding criteria.

Conclusion

That's it for how to display hidden files in AstroNvim's neo-tree.
It seems better not to touch ~/.config/nvim/lua/plugins too much.
