Reload config

[fadri14]

Hello,
On my pc I have configured a light mode and a dark mode and so I would also like a light mode and a dark mode on neovim. I have created a separate script that changes my config file but neovim does not apply config updates in real time, so I would like to make a keyboard shortcut in neovim to reload the config but the command so ~/.config/nvim/init.lua does not reload my config.

Thanks to all those who will take the time to help me.

set bg=light / set bg=dark are likely the Vim commands you're looking for if you want to change between light and dark mode in your theme. You could call these in lua by using vim.cmd('set bg=light) for example, then bind some key to a function that toggles between light / dark themes.

Reloading (all) config is not supported, since it's simply not possible in general (there is too much state that config -- including plugins -- can change).

Instead, you should write a script that only changes bg and reloads the colorscheme. There are already a few plugins out there that claim to sync Neovim colors to system dark mode; looking at these is your best bet.

Thanks for your answers but I'd like to clarify that when I talk about light and dark themes, it's not just the background but the whole theme. That is, I use the onedark and catpuccin themes. So if I can't restart the whole config, I need to create a function that applies one of the two themes alternately? Could I use this kind of command in such a function?
require('catppuccin').load()
even if the other theme has already been applied?

That depends on the plugin. Colorschemes are meant to be reloaded (with :colorscheme <foo>); if the colorscheme insists to be a Lua module, then this becomes more difficult and has to be handled by the plugin itself.

J'ai créé la fonction suivante mais rien ne se passe quand je l'appelle avec :lua changeTheme()…
`
function changeTheme()
local current_theme = vim.fn.execute('colorscheme', '')

local new_theme = ''
if current_theme == 'onedark' then
    new_theme = 'catppuccin-latte'
else
    new_theme = 'onedark'
end

vim.cmd('colorscheme ' .. new_theme)

end
