Usage

Assuming you are using linux:

• Clone AstroNvim in the same location the variable astro_config gives you.

git clone https://github.com/AstroNvim/AstroNvim ~/.local/share/astronvim/core

• Create a configuration folder in the same location the variable user_path gives you.

mkdir -p ~/.config/astronvim

• Copy the content of the gist in your config folder.

~/.config/astronvim/entry.lua

• Make an alias that uses the new entry point.

alias code='nvim -u ~/.config/astronvim/entry.lua'

• Use the new command to open neovim with AstroNvim.

code

To customize AstroNvim in this new setup create a lua module called user in the configuration folder.

mkdir -p ~/.config/astronvim/lua/user

Inside that new folder you create a file called init.lua. Check out this example configuration to know what you can do.
