Support for junegunn/vim-plug to install

[mjj29]

Hi there, I'm using vim-plug to manage my plugins, and it's working great for github/copilot, but installation failed (just seemed to hang) when I tried using it for this repository. Is there any way you can support that plugin manager as well?

Thanks,
Matt

Hi @mjj29 There is a user confirmed and it's working for Vim Plug https://discord.com/channels/1200633211236122665/1200633212041449606/1205188460277665822

Let's ping him if he could help you on this.

[mjj29]

Yes, would be good to hear from someone else who has got it working (I don't have access to that discord server)

I asked Chat GPT to translate the installation instructions for lazy.nvim to vim-plugin instead.

This is what I ended up with, which worked for me:

" Place this between call plug#begin() and call plug#end()
Plug 'CopilotC-Nvim/CopilotChat.nvim'

" After call plug#end(), configure the plugin options with VimScript
let g:copilotchat_options = {
      \ 'show_help': 'yes',
      \ 'debug': v:false,
      \ 'disable_extra_info': 'no',
      \ 'proxy': '',
      \ }

" Key mappings

nnoremap <leader>cct <cmd>CopilotChatTests<cr>
xnoremap <leader>ccv :CopilotChatVisual<cr>
xnoremap <leader>ccx :CopilotChatInPlace<cr>

After adding the plugin with vim-plug, run :PlugInstall in Neovim to install the CopilotChat.nvim plugin.

Next, the manual step of running :UpdateRemotePlugins is still necessary with vim-plug to ensure that Neovim properly recognizes the plugin's commands and functionalities. After running this command, restart Neovim.

To verify that the plugin has been correctly installed and initialized, you can check the ~/.local/share/nvim/rplugin.vim file to see if the commands have been registered as expected.

Finally, restart Neovim to ensure all changes take effect and the plugin is ready to use.

OK, I got further by installing the following things with pip:

pip3 install pynvim
pip3 install python-dotenv
pip3 install requests
pip3 install prompt_toolkit

which let UpdateRemotePlugins run, but now I get:

pynvim.api.common.NvimError: Vim:E121: Undefined variable: g:copilot_chat_user_prompts

Could you share your setup here? @mjj29

I've run :PlugInstall and :UpdateRemotePlugins, both of which completed successfully now, but when I run :CopilotChatInPlace I get:

Could you add those to Plug? @mjj29

Plug 'CopilotC-Nvim/CopilotChat.nvim'
call plug#end()

let g:copilot_chat_proxy = ""

}
let g:copilot_chat_show_help = 'yes'
let copilot_chat_disable_separators = 'no'
let copilot_chat_hide_system_prompt = 'yes'

Is this on ~/.config/nvim/vim-plugs/plugins.vim? For me, this code after call plug#end doesn't get recognized by nvim. I'm using vim-plug on Nvim.

[nekowasabi]

My neovim's setting with vim-plug.
I have CopilotChat working with this configuration.

lua << EOF
local copilot_chat = require("CopilotChat")
copilot_chat.setup({
  debug = true,
  show_help = "yes",
  prompts = {
    Explain = "Explain how it works by Japanese language.",
    Review = "Review the following code and provide concise suggestions.",
    Tests = "Briefly explain how the selected code works, then generate unit tests.",
    Refactor = "Refactor the code to improve clarity and readability.",
		Aaa = "hello",
  },
  build = function()
    vim.notify("Please update the remote plugins by running ':UpdateRemotePlugins', then restart Neovim.")
  end,
  event = "VeryLazy",
})
