Set 4 Space Indent in Emacs in Text Mode

Question

I\'ve been unsuccessful in getting Emacs to switch from 8 space tabs to 4 space tabs when pressing the TAB in buffers with the major mode text-mode.

Answer 1

Just changing the style with c-set-style was enough for me.

Answer 2

From my init file, different because I wanted spaces instead of tabs:

(add-hook 'sql-mode-hook
          (lambda ()
             (progn
               (setq-default tab-width 4)
               (setq indent-tabs-mode nil)
               (setq indent-line-function 'tab-to-tab-stop) 
               (modify-syntax-entry ?_ "w")       ; now '_' is not considered a word-delimiter
               (modify-syntax-entry ?- "w")       ; now '-' is not considered a word-delimiter 
               )))
