2.5 Select ~/.vim/pack/bundle/start/vim-gnupg as "Local Folder". In "Local Folder" drop down, choose "Other" at the bottom, click on "Home" on the left bar, choose Create Folder icon on top right, and enter .vim and then repeat the same to create each sub folders - pack, bundle, start, vim-gnupg. Then click Clone on the top right.
Now you can just right click on any encrypted file in your file manager and open with GVim. This plugin will decrypt the file and let you view or edit its contents. You can enable "Always use for this file type" to just open it by double clicking it next time.
Advanced/Command line setup
1. Install vim using your package manager
sudo apt install vim
OR (Those who prefer the GUI way of doing things can use vim-gtk3).
sudo apt install vim-gtk3
2. Install vim-gpg plugin
2a If you are on a debian based distro. There is a package called `vim-scripts` that already has this plugin. So installing this package would make things a lot easier
sudo apt install vim-scripts
Now add the line "packadd! gnupg" to your ~/.vimrc. You can use a graphical text editor like GNOME Text Editor or GVim to open ~/.vimrc file and add this line to the end of the file (if it has some contents already or just add it to the start if the file is empty).
echo "packadd! gnupg" >> ~/.vimrc
That's it ! Now you can open your gpg encrypted file using vim and it will ask for your passphrase.
OR
2b You can use Vim's package support to contain the plugin in its own directory.
mkdir -p ~/.vim/pack/bundle/start
cd ~/.vim/pack/bundle/start
git clone git@github.com:jamessan/vim-gnupg.git
Vim will find and load everything on its own, without mixing the files with others.
