2023-04-27

what is dis ? ==> le script to install nvim appimage on a distro without sudo access

why? ==> coz my lab teacher wont give me sudo access

what does this do? ==> curls the nvim binary and install it in $HOME/bin/ and configures a sane init.vim file

# Define the path where you want to store the Neovim configuration file.
NEOVIM_CONFIG_PATH="$HOME/.config/nvim/init.vim"

# Create the directories if they don't exist.
if [ ! -d "$HOME/bin" ]; then
    mkdir "$HOME/bin"
