如何使用快捷方式重新加载用 lua 编写的 Neovim 配置？

Question

I want to reload my neovim configuration files with just a couple of keystrokes instead of having to restart the app. I was able to do this when using an init.vim with the following command:

nnoremap <leader>sv <cmd>source $MYVIMRC<CR>

$MYVIMRC points correctly to my config entry point.

The problem is that I switched to using lua , and now I can't do the same. I have read the docs and tried variants of the following without success:

util.nnoremap("<leader>sv", "<cmd>luafile $MYVIMRC<CR>")

Finally, I found a solution doing this:

function load(name)
    local path = vim.fn.stdpath('config') .. '/lua/' .. name .. '.lua'
    dofile(path)
end

load('plugins')
load('config/mapping')
load('lsp/init')

Which is buggy and feels wrong.

Is there any way to do this? I read the example in vimpeccable , but I want to see the other available options since I would rather not install another plugin.

I know that plenary includes a function to reload modules, but I don't understand how to use it. A complete example of that would be good too since I already use plenary in my config.

Answer 1

I ended up going for the following:

I have a util.lua file that defines de following:

_G.load = function(file)
    require("plenary.reload").reload_module(file, true)
    return require(file)
end

Then, instead of writing require(...) , I write load(...) and the only file I require is util.lua , which is also the first one.

Then I have the following mapping defined:

util.nnoremap("<leader>sv", "<cmd>luafile $MYVIMRC<CR>")

Which reloads my whole config.
