• What is Emacs

What is Emacs

• Emacs is a super extensible programmable "editor"

• You can write documents, code, agendas, emails, etc.

• Editor in quotes because it does much more than edit stuff

  • Tetris is in Emacs by default
  • Browse the web!

  • I don't really know why you would though, but hey it's there

    • It can even be your window manager with the package exwm
  • Written in Elisp
• A dialect of lisp written specifically for Emacs

• All configurations are done in this language

  • Example:

    (split-window-below)
    (split-window-right)

  • By default, Emacs does not have a way to go back a "window"

    • Time to learn some Emacs Jargon!

    • Buffers

      • Buffers are kind of like tabs in a "regular" editor

    • Windows

      • These are where buffers can be drawn
      • Like splitting in vim

    • Frames

      • These are Emacs instances

      • What you would normally call a "window"

        • You really only need to know about buffers and windows
      • Let's look at some Elisp to do this for us!

      (defun go-back-window ()
    	(interactive)
    	(other-window -1))

    • Now if we want to bind this function to a key we can!

    (global-set-key (kbd "C-c u") 'go-back-window)
