[Yum] I'm back and future stuff

[Vladimir Bormotov]

		Hi!

SV> I think I will tend to agree with linus, big patches suck. Can you
SV> isolate what they are patching? ie: a reget patch, a tabbing patch, a
SV> doc patch etc etc.

 You can help to minimize patches.
 
 just read  
 
 http://www.python.org/doc/essays/styleguide.html 
 http://www.python.org/peps/pep-0008.html
  
 and aplly style recomendation to source code as rules ;)


 brief "python-styling":
 
 
 Indentation
 
   4 spaces for one level.  
   
   for example, look at yum-0.8.9/lilo.py, class LiloConfigFile.
   
   cass declaration at first posotion.  Nice.
   def __repr__ - indented with 4 spaces.  Very nice.
   s = "" indented with one tab character.  Ooops!!!!
   
   look below, into def needsEnterpriseKernel:  
   
   for l in f.readlines() indented with 4 spaces, but body indented with
   tab character.  ;-/
 
 
   === styleguide cut ===
   Tabs or Spaces?
 
    Never mix tabs and spaces. The most popular way of indenting Python is
    with spaces only.
   === 
   
  Please, NO TAB CHAR IN PYTHON CODE! 
  
  
 Maximum Line Length
 
   Guido say: "please limit all lines to a maximum of 79 characters".
   PEP-8 say: "limiting the length to 72 characters is recommended"


 Whitespace in Expressions and Statements
 
   NO spaces:
    * Immediately inside parentheses, brackets or braces
    * Immediately before a comma, semicolon, or colon
    * Immediately before the open parenthesis    
    * More than one space around an assignment operator
    * around the '=' sign when used to indicate a keyword argument or a
      default parameter value
 
   Always put spases:
    * surround these binary operators with a single space on either side:
      assignment, comparisons, Booleans
  
  In our code we always use one space after comma.  No trailing
  whitespeces.
 

 Comments
 
   starts with a # and a single space (unless it is indented text inside
   the comment)
