  To: Emacs

I'm currently using 
GNU Emacs 23.3.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10 on
Ubuntu 12.04, but expect to have to also use --no-window-system
("console mode") on occassion.

I have used emacs extensively in the distant past (up 'til 2008), so
am re-acquainting myself with the system.

I have much legacy python code that has "hard tabs" and to meet
the python style guides, will have to be converted to "soft tabs".
I.E. TAB => "    "

I also need to configure emacs so that TAB (or Ctrl-i) inserts four
spaces instead of the TAB character.

I currently have this in my .emacs [code]
(add-hook 'python-mode-hook
            '(lambda ()
               (turn-on-font-lock)
               (setq default-tab-width 4)
               (setq tab-width 4)
               (imenu-add-menubar-index)
               (setq imenu-sort-function 'imenu--sort-by-name)))

[/code]

I'd welcome any and all advice, pointers to previous discussion
would are solicited.

thanks

To remove tabs, make the whole buffer the region:

C-x h

then run untabify:

M-x untabify

  Thank you. That was very simple. I note from 'help that
  'default-tab-width is obsolete.

Please don't quote your lambdas.

  It is a misbehavior noted frequently in examples,
  which I followed.

  After reading your advice, I found

I know, which is why I try to bring it up whenever I see it, in the hope
that 10 years from now, there will be fewer such bad examples.

  I have been inspired to google "emacs best practices"
    http://www.gnu.org/software/emacs/manual/html_node/elisp/Coding-Conventions.html

  and "elisp lint"
    https://github.com/nschum/elisp-lint

You might also want: (setq indent-tabs-mode nil)

You might also want to try this mode: https://launchpad.net/python-mode/
instead of the one included in Emacs. For some aspects, it is more
powerful/confortable (YMMV)...

  I believe I may have used that years ago, it was a good choice
  even then. Thanks for reminding me.
