Vim Sessions

Vim’s built-in session mechanism¹:

A Session keeps the Views for all windows, plus the global settings. You can save a Session and when you restore it later the window layout looks the same. You can use a Session to quickly switch between different projects, automatically loading the files you were last working on in that project.

:h session
:h mksession
:h 'sessionoptions'

• To save the session :mksession, will save the session in a Session.vim file.
• To restore a session :source ~/Session.vim or vim -S Session.vim
