Replace tabs with spaces in vim

Question

I would like to convert tab to spaces in gVim. I added the following line to my _vimrc:

set tabstop=2

It works to stop at two

Answer 1

IIRC, something like:

set tabstop=2 shiftwidth=2 expandtab

should do the trick. If you already have tabs, then follow it up with a nice global RE to replace them with double spaces.
