Force Emacs to use tabs

So, I’m not wasn’t really a fan of using tabs to indent code. I like spaces. It means that the code always look the same no matter what editor or OS you’re viewing it in but since using tabs (as is the codestyle at $work), I have come to [kinda] like it and I can see the reasoning behind it.

When editing code, I like using one of two editor - emacs or vim. I can use vim to a pretty good standard but I still love emacs as I don’t like the modal editing you get with vim (having to enter edit mode to type). I like just opening the document and code away. So to cut a long story short, to make emacs always use tabs (instead of spaces) to indent code, I added these settings to my ~/.emacs file:

;; Turn on tabs
(setq indent-tabs-mode t)
(setq-default indent-tabs-mode t)

;; Bind the TAB key
(global-set-key (kbd "TAB") 'self-insert-command)

;; Set the tab width
(setq default-tab-width 4)
(setq tab-width 4)
(setq c-basic-indent 4)
