hello,
Coming from windows/Delphi,
I've been using Python for half a year now.
For reading/writing windows ini-files,
I used ConfigParser (already much more difficult than Delphi ;-)
Now I needed an windows ini-file (not a registry file),
where the case of the keys was preserved
(ConfigParser makes all keys lowercase).
So someone advised me to use ConfigObj,
which should be superior to ConfigParser.
So I try to read the manual,
looks very nice and well written.
But when I read the introduction,
"*ConfigObj* is a simple but powerful config file reader and writer"
I miss the "simplicty".
Apparently this simplicity yields for a certain group of programmers,
probably coming from Linux / C,
certainly not for windows/Delphi programmers.
Now my problem is very-very simple,
but I don't get it done,
so maybe someone get give me a few simple ;-) hints.
I open an ini-file for reading:
ini = ConfigObj ( filename )
I want to see what sections are ther:
ini.sections
Now I want to see what keys are in 1 specific sections:
??????
things like
ini.values()
ini.items()
give me all kind of key-value pairs, but without knowing in which
section they are stored ??
thanks,
Stef Mientki

Still one other small question, which must be peanuts for you (and others), how do I read a value as a normal string ? When I've an inifile with following content: size = (134,433) ConfigObj gives me back a list ['(134', '433)'] Undoubtedly usefull in most cases (although the brackets look weird to me ;-), but as I move around and manipulate these "things" all over in my program, I just want to handle 1 type, for which I've chosen the string type. cheers, Stef |

Hmmm... doesn't that happen automatically on Windows?
ConfigObj does expose a 'newlines' attribute ('\r\n', '\n', or '\r'). It
does however go to great lengths to preserve line endings in a config
file it has read - or to use the native ones for the platform.

Yes I read that before,
but doesn't mean that everyone is using them (explictly) ;-)
(I mainly do signal analysis and simulation)

Yes I read that ...
so I tried
ini.list_values = False
but that didn't work.

Thanks that works ok.
So why doesn't
ini.list_values = False
this work ?
cheers,
Stef

Another question: is it possible to force the normal windows end-of-line (CR+LF), when writing to the config file ? cheers, Stef |

Hmm.. now you told me, it does indeed ???
So I guess my observation was caused by a crash or error somewhere in my
program.

Great component,
- my names in the name-value pairs keep their case
- the order of the items in a section is preserved
thanks very much Michael.
I'll let you know when I release my program ( a hardware / software
simulator for microcontrolers),
so you can add it to the " Real World" chapter.
cheers,
Stef
