Xen devel - May 2005 - [PATCH] remove tabs from xm/main.py

hello,

while investigating xm/main.py, i found that it is mixed with tabs and
whitespaces. that is annoying and may get us misleaded when reading
code. looks like that the conventional coding style of Python (and
also C?) in Xen is to use (4) whitespaces instead of tabs? could
anybody confirm this?

i searched in all tree and found bunch of files like this. if nobody
complains, i will catch them all (both C and Python codes) and send in
1 patch to the list. any idea?

this patch replace tab with 4 whitespaces in (only) xm/main.py

Particularly for python, this kind of patch can be *really* dangerous.
Please can you confirm that you fully understand the python indentation
rules (I don''t), and that the patch was generated mechanically by a
script. 

Thanks,
Ian

yes, indentation for C codes is not that important, but that is a
serious problem with Python. you are always adviced to *never* mix tab
and space when indenting Python code. that is *evil*. we must consider
this as bug, and fix them all.

looks like all the Python code use 4 spaces to identation. could any
developers who wrote those code confirm that they set tab as 4 spaces
in their editor?

i will try to fix all the tabs by replacing them with 4 spaces, check
it carefully to make sure no error is introduced, and send in the
patch (for Python code only).

aq
