If you add the commands to your .vimrc (or init.vim if you are using neovim), the preferences will persist between sessions. If you are referring to having the code to a problem persist between sessions, you can write the file containing the code to disk. When you next open vim, if you do so in the directory where you saved the file, the code will persist between sessions.
