emacs-term-toggle VS eshell-toggle

For the background story: I have modified an old Emacs library to toggle to a shell in the current working directory, which I am very happy with since it is very small (~100 sloc) and very predictable (always below the buffer I edit). Now, I just want to add a small touch for working with ielm: when I toggle ielm, I wish to set its working buffer to the buffer I edit. Since I will call this in ielm-mode-hook, I need to know the last buffer I was editing, i.e. "the buffer I came from".

You can try this terminal toggle. Put eshell or term on a key, term-toggle-eshell or term-toggle-term and you can press that key to toggle ehsell/term on or off as you need it.

Or term-toggle, which despite the name has nothing to do with eshell-roggle 😀. It can toggle all of available "terms" in Emacs, if someone wants to add support for vterm I am happy to get a PR.

You can also try this little package if you need to fast pop-iup and dissmiss a term/eshell/ansi-term/ielm

There seems to be [equake](https://gitlab.com/emacsomancer/equake) which opens a whole frame for the console. And [emacs-term-toggle](https://github.com/amno1/emacs-term-toggle), but this doesn't support vterm.

I have used for many years something called term-toggle.el, and I have recently rebuilt it to better suit my (minimalistic) need: https://github.com/amno1/emacs-term-toggle. Better shell seems to do a similar thing, not really the same though. I have sudo-open-file since before, which is enough for my needs when I need to edit some config script on my system.
