I have my emacs setup to use one tab per indent level, and to display
tabs as four spaces. I believe that this is all controlled by the
following three settings found in the customization section of my .emacs
file.


(custom-set-variables
'(py-indent-offset 4)
'(tab-width 4)
'(py-smart-indentation nil)
...
)

Thanks Gary,

This gets me close enough to be functional, but isn't quite there. The
problem is that if there are spaces in there, it won't reset them to
tabs, which is what I would like. For the most part, it won't be an
issue, but I'd just like it to be totally consistent.

What I really want is for Python mode to have an option like
"use-only-tabs" or "use-only-spaces". In fact all you would really need
to do is have py-indent settable to an arbitrary string, rather that an
integer. Then folks could set it to be four spaces, or a tab, or two
tabs, or whatever.

Quite frankly, I'm confused as to why anyone would think it's a good
idea to mix tabs and spaces at all, but that's what we're stuck with.

Sounds like a one-shot pass over the code with sed, tr, indent or Emacs'
tabify command should do the trick. I'm not used to TAB==SPC*4 mode, so I
won't hazard a guess at the appropriate settings, but a little
experimentation should converge on a solution fairly quickly.

In fact, maybe Emacs' tabify command will just do the right thing if you
have tab-width set properly. Try C-h f tabify RET.

M-x tabify should do it unless you have different indentation levels
(some with equiv 4 spaces, some with equiv 8 spaces). In that case,
tho' I haven't tried it, I'm guessing Gordon's tabcleaner.py should do
the trick nicely.
