I have to work with C/C++ files with a very ugly and inconsistent
indentation (many developers adding things with no style guide). This
is very distracting, and since I cannot change them (to avoid conflicts
when taking/carryng changes from/to other branches), I had think that
for read-only files (those that I have not opened in the revision
control system), it would be nice if emacs could run automagically the
"indent" program so I can see the code "beatyfully" indented.
I didn't find anything obvious on the net for that. I do not wanna
modify files in disk, only to make emacs to put the indent output in
the buffer without changing variables like `buffer-file-name' and so. I
would like this to be done in a transparent way when opening a C/C++
file (via find-file, find-tag or whatever).
Before trying to code something like that myself (and most probably
reinvent the wheel), I would like to know if anybody knows if this (or
something similar enough I could reuse/modify) is already available.
Any ideas welcome.
