Emacs Configuration

Tested with emacs version 26.3 in Debian 9 (windows subshell) & 10

Initialization

Just clone this file in your home directory (~)

Emacs automatically looks for a file on the path ~/.emacs.d/init.el on startup

The init file is also setup to load in any files from the custom_elisp folder as well as the custom.el file

Don't edit the custom.el file, it's automatically generated

What's up with the zip file?

It's a backup, you can unzip it to make sure you have the same elpa directory used in testing, or you can just leave it alone/delete it

If you don't unzip the file, the elpa folder should automatically regenerate the first time you run emacs

.org files

These are used to manage the README (this file)

tangle: C-c C-v C-t export: C-c C-e

Keybindings

All custom keybindings can be found in the init.el file.

Common emacs commands for those who are new

Simple definitions by example

M stands for "Meta" and by default is the alt key
C stands for "Control" and is default the control key

"Buffer" is the open text area, it's not called a window since you can split your screen into multiple buffers

C-f          Means hold Ctrl and press f
M-p          Means hold alt (meta) and press p
C-x f        Means hold Ctrl and press x, release Ctrl and press f
C-x C-c      Means hold Ctrl and press x, keep Ctrl down andpress c
C-M-e        Region is the word for selection
M-% or M-S-5 Means alt + shift + 5

common commands

C-f move one character forwards
M-f move one word foreward
C-b move one character backwards
M-b move one word backwards

C-p move to previous line
C-n move to next line
C-a move to start of line
C-e move to end of line

M-< move to the beginning of the buffer
M-> move to end of buffer

C-v page down
M-v page up
C-l center page on cursor (multiple clicks move it to top/bottom instead of center)

M-^ move current line and append it to the prior line, removing all whitespace and adding back in a single space

M-x outline-minor-mode collapses function definitions in a file to a mere {...}
M-x show-subtree If you are in one of the collapsed functions, this un-collapses it In order to achive some of the feats coming up now you have to run etags *.c *.h *.cpp (or what ever ending you source files have) in the source directory
M-. If you are in a function call, this will take you to it's definition
