Save *everything* across sessions

Question

When I quit Emacs, nothing is saved, such as my search history, my command history, my replace strings, etc.

I want EVERYTHING saved. How do I do that?

And by everything, I mean at least the following;

• Cursor, I mean, point :) position in each file Undo history for each file

• Command history. This is tricky to specify because unlike in the other editor, commands are issued in various ways. C-x, etc. M-x, etc.

• Search and replace history

It should feel as if I never exited the session.

I do not even know where to look for. Google shows me some scary cryptic functions, etc. And talks about packages, etc.

Is there an easy, newbie friendly way out?

Answer 1

It sounds like you should start, as others have said, by getting to know (well) desktop.el. Add to that savehist.el and saveplace.el. Others may have other suggestions.

savehist.el will take care of histories and rings (they are variables), including command histories (command-history, extended-command-history ...).
