Wrote a little "user-friedly" wrapper for ConfigParser for a KDE's
SuperKaramba widget.
( http://www.kde-look.org/content/show.php?content=32185)
I was using 2.4.x python docs as reference and
ConfigParser.re ad('non-existent-filename') returns [] in 2.4.x
One user with 2.3.x reported an error stemming from my use of
len(cfgObject.r ead('potentiall y-non-existent-filename'))
File "/home/web/Downloads/afoto-1.5b6.skz/localConf.py", line 53, in load
TypeError: len() of unsized object
Can anyone tell me what cfgObject.read( 'potentially-non-existent-filename')
returns in 2.3.x?
My output:
>>import ConfigParser
cfg = ConfigParser.Co nfigParser()
a = cfg.read('adsfa sfdasfd')
a, len(a), type(a)
([], 0, <type 'list'>)
Thx in advance.

That agrees with the docs since read returns a list of successfully parsed
filenames. Note the docs also say this was added in 2.4.

I suspect it never returns anything which means you are getting None instead
of a list, which would give you the exception above.

I just looked at the

(note the version number) and see the following:
"If none of the named files exist, the ConfigParser instance will contain
an empty dataset." Which to me means []. To the least of it, the statement
should be clarified, but I would still kindly prefer to have someone
respond / confirm the procedure bellow gives different results in 2.3.x.

That says nothing about the return value. It says that the ConfigParser
object will contain an empty data set, ie:
config.sections () == []
NOT
config.read(['doesnotexist.c fg']) == []
since config.read does not explicitly return anything, and therefore you get
None.

I'm trying to subclass ConfigParser so I can use a custom __read method (the

In the following code, I bind __read_ini to __read and override __read so it
can choose between __read_ini and __read_custom. But it seems that
__read_custom never gets called when I expect it to aways be called. I have

It looks like ConfigParser will accept a list to be writing to the
*.ini file; but when reading it back in, it treats it as a string.
Example:

print thingname, "value:", thing

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
