Installing with Packer for neovim (nvim)

[deft01]

Hello,

I tried installing this with Packer (nvim plugin manager) with use('chimay/wheel').
But I get this error while running vim :

Erreur détectée en traitant /home/user/.config/nvim/init.lua :
E5113: Error while calling lua chunk: /home/user/.config/nvim/init.lua:123: attempt to index field 'wheel_config' (a nil value)
stack traceback:
        /home/user/.config/nvim/init.lua:123: in main chunk
[coc.nvim] build/index.js not found, please install dependencies and compile coc.nvim by: yarn install

I think this is because I'm not using the plugin installer you recommanded.
I believe this is not related to it, but my lua config looks like :

vim.g.wheel_config.file = '~ /.local/share/wheel/auto.vim'

hello,

Before filling the wheel_config dict, you have to initialize it. In vimscript :

let g:wheel_config              = {}
let g:wheel_config.maxim        = {}
let g:wheel_config.frecency     = {}
let g:wheel_config.display      = {}
let g:wheel_config.display.sign = {}

I suppose it translates in lua to:

vim.g.wheel_config              = {}
vim.g.wheel_config.maxim        = {}
vim.g.wheel_config.frecency     = {}
vim.g.wheel_config.display      = {}
vim.g.wheel_config.display.sign = {}
