E5113: Error while calling lua chunk: vim/_meta.lua:0: Invalid option (not found): 'data_dir'

Question

I am using neovim config from custom directory and also want that it stores its data in custom directory. So i set this in my ~/.config/nvimcustom/init.lua :

vim.opt.data_dir = '~/.local/share/nvimcustom/'

But on running nvim -u ~/.config/nvimcustom/init.lua , I am getting this error

Error detected while processing /home/venom/.config/nvimcustom/init.lua:
E5113: Error while calling lua chunk: vim/_meta.lua:0: Invalid option (not found): 'data_dir'
stack traceback:
[C]: in function 'nvim_get_option_info'
vim/_meta.lua: in function '__index'
vim/_meta.lua: in function ''
vim/_meta.lua: in function '__newindex'
/home/venom/.config/nvimcustom/init.lua:2: in main chunk

I just want that my neovim config is present in custom directory and also all the plugins and otther data it stores due to this custom config is stored in a custom directory. How to do that. I want to do it so that when I run normal nvim, I can have different configuration and whne I run nvim using -u flag, I can have different configuration

Answer 1

Here is what I do on Windows. I have introduced a nvimcustom.bat script:

set XDG_CONFIG_HOME=%HOME%\nvimcustom
set XDG_DATA_HOME=%HOME%\nvimcustom
set XDG_STATE_HOME=%HOME%\nvimcustom

start Neovim\bin\nvim-qt.exe %*

On Linux it would be a nvim.sh script:

XDG_CONFIG_HOME=$HOME/nvimcustom
XDG_DATA_HOME=$HOME/nvimcustom
XDG_STATE_HOME=$HOME/nvimcustom

nvim %*

The init.lua should then put into ~/nvimcustom/nvim
