Vim Sessions

Vim editor also supports sessions just like a browser like firefox.

If you have 8-10 tabs having > 30 files open in vim [ this should be the case if you’re working on a project of reasonably big size] , and you have to reboot your PC or restart x server for that matter, it can get really irritating to close vim, and then open files one by one again :(.

Vim session solve exactly this problem. When you have to close your vim for any such thing, you can just do

:mksession /path/to/session/file.vim

This will store everything in current vim session including all open files, all visible buffers, window sizes and keyboard mappings etc.

Now when you want to restore vim from this particular session, you can just do

command_prompt$  vim -S /path/to/session/file.vim

This will restore everything just the way it was :).

You should have vim compiled with session support in order to be able to do this. I think from version 7 onwards, even the standard vim supports this by default. Also, for the setting to work, you need to add the following line to your .vimrc

set sessionoptions=blank,buffers,curdir,folds,globals,help,localoptions,options,resize,tabpages,winsize,winpos

PS: Vim session doesnt keep track of undo history in each open file.
