Getting a lua error after configuring the plugin for Vim 9.1

[iulianbarbu]

The error I am getting is:

.../plugged/lsp-progress.nvim/lua/lsp-progress/defaults.lua:171: attempt to call a nil value (field 'deepcopy')

My vimrc contains this setup:

lua require('lsp-progress').setup()

I have installed lua5.4. Also, in terms of nerd-fonts, I set it up so that font-patcher is on the path. I am not sure if this is what the plugin needs or I am totally off.

I am a vim/lua/nerd-fonts newbie, so my questions revolve around:

1. What Lua version is best so that the plugin works for Vim too?
2. What exactly should I install for nerd-fonts?

hi @iulianbarbu ,

1. I didn't design this plugin to work for Vim, it's only for Neovim. I don't think it can work for Vim, since I implement this plugin with Neovim's lua api, which is totally not compatible with Vim.

2. The dependencies for nerd-fonts is in this line:

   https://github.com/linrongbin16/lsp-progress.nvim/blob/b673377c50ebaf37053f23cc3caeeb6d469ba1c1/lua/lsp-progress/defaults.lua#L133

   It uses the nf-fa-gear font in nerdfonts.com - cheat-sheet (see below screenshot):

   

   It looks like this (if you have a properly configured nerd font):

   

   I recommend you choose & install one font from nerdfonts.com, and remember to configure the installed font in your terminal (iTerm2 in macOS, Windows Terminal in Windows 10, Gnome Terminal in ubuntu gnome desktop, or kitty/wezterm/alacritty/etc).

Hi @linrongbin16 ! Thanks for the response and clarifications.

I guess I'll have to look into neovim for now to enable this.

Also, I think this issue can be closed now.

hi @iulianbarbu ,

FYI, in neovim, you still need to install lsp servers, and configure them to make this plugin work.

actually it's not going to be very easy.

personally I am using below plugins to work with this 'lsp-progress' plugin:

• nvim-lspconfig: it's a common configuration layer, to help you configure those lsp servers (maybe because there's still some gap between nvim and lsp). this is almost the lsp standard in neovim that you must install.
• mason.nvim: a plugin to help you manage lsp servers. For example you need clangd for c/c++, pyright for python, etc. you can install them manually and export them to $PATH so nvim can see them. But with mason, you can install/upgrade/remove these lsp servers. Mason is like venv to python/pip.
• none-ls.nvim: Sometimes only lsp server is not enough, because some linters/code formatters/etc are just a shell command, for example clang-format for c/c++, black/yapf for python. So none-ls is using neovim itself as a lsp server, thus transform those formatters/linters message through the LSP protocols.
• lualine.nvim: a most popular statusline plugin for Neovim, just like airline/lightline in Vim. This plugin is working as a component with a statusline plugin.

At last, compare with Vim, Neovim is actually much more heavy engineering because the lua language requires user write a lot. But also it provide much more feature.

Hope these introduction helps you enjoy neovim with lsp.
