Using C/C++ (cc-mode), emacs sometimes re-indents text as I'm typing.

For example (# for indentation, the first 4 are a tab):

enum {
####/

Typing *, becomes:

enum {
######/*

(inserting 2 extra spaces)


Is there a way to disable this?

  • Right, I wasn't sure when asking. – ideasman42 Mar 8 '17 at 9:49
  • This must be a duplicate, but I don't have time to track it down. Maybe search for electric-indent-mode... – Drew Mar 8 '17 at 16:47
  • emacs.stackexchange.com/questions/31038/… is related, if not an exact duplicate. – npostavs Mar 8 '17 at 20:11

It turns out electric-mode causes re-indentation, it can be disabled:

To disable, add this to your startup.

(when (fboundp 'electric-indent-mode) (electric-indent-mode -1))

An alternative is to disable re-indenting just for comment characters (since its handy to keep for braces).

;; Prefer no indentation for comment chars.
(define-key c-mode-base-map "/" 'self-insert-command)
(define-key c-mode-base-map "*" 'self-insert-command)
