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

(setq-default indent-tabs-mode nil)
(setq-default tab-width 4)
(setq indent-line-function 'insert-tab)
(setq c-default-style "linux") 
(setq c-basic-offset 4) 
(c-set-offset 'comment-intro 0)

this works for C++ code and the comment inside too
