overview
This is my personal emacs config which currently runs on emacs 26.1 (currently the latest package from the Arch Linux official repos).
I use this for a variety of purposes:
- maintaining my todo list/GTD workflow (org mode)
- unified interface for system administration (dired, shell, git, ediff)
- email (mu4e, work in progress)
- editing some of my favorite languages (R, Lisp, Haskell, Lua, Python)

If dired is to replace all other file managers it must handle devices. This function assumes all my devices are mounted on /media/$USER and that udevil is installed. It provides mount and mount/follow ops for all usb removable media and follow/unmount for all mounted devices (note the latter includes things that are not mounted here such as samba drives, which I normally hotkey to my window manager). This almost replicates the functionality of gvfs that I actually use without the bloat; the only missing piece is MPT for android (which will come later).

Some of these commands just get in the way of being evil (which really means that I keep pressing them on accident). Rather than nullifying them completely, tuck them away in the emacs state map in case I actually want them.

This is somewhat strange because all I really care about is moving between lines and to the beginning and end as normal. However, I like the idea of thinking of paragraphs as one line (eg df. deletes a sentence even if on multiple lines). Opinion subject to change.

Comint-based inferior modes often are not evil (eg intero and ESS). Configure this similarly to term (see below) where C-j/k navigate cmd history and insert mode goes to cmd input line.

The function keys are nice because they are almost (not always) free in every mode. Therefore I use these for functions that I need to access anywhere, but not necessary extremely often (because they are out of the way and harder to reach).
