Was: Parameters of handleArgs
I went back to this conversation with Russell, and tried to use it
in an other way. I have console encoding problems with this command
with Cyrillic letters: replace.py -catr:Венгрия . @ -lang:ru
-excepttext:"[[hu:" -save:magyarok.txt -always One way is to
urlencode the Russian category. Other way is to insert it into a
script. (DOS batch files won't work, I already tried.) So what I
did: import replace replace.main(u'-catr:Венгрия', '.', '@',
'-lang:ru', '-excepttext:"[[hu:"',
'-save:magyarok.txt') This
results in an error message: File "C:\Pywikipedia\replace.py", line
582, in main for arg in pywikibot.handleArgs(*args): File
"C:\Pywikipedia\wikipedia.py", line 7795, in handleArgs arg =
_decodeArg(arg) File "C:\Pywikipedia\wikipedia.py", line 7767, in
_decodeArg return unicode(arg, config.console_encoding) TypeError:
decoding Unicode is not supported If I omit u from before -catr, no
error is thrown, but the name is erroneously decoded. Now comes the
tick! I went to line 7795 of current wikipedia.py (r9894) as shown
above, and commented it out. Now my script runs perfectly! I love
it!
I don't want to spoil handleArgs() and I know this is an unusual
use of it. But is it possible in some way to pass a parameter to it
that tells _decodeArg to shut up? Or is there another correct way
of passing Unicode parameters from within a script?

I see in a couple of bots this construction:
def main(*args): for arg in pywikibot.handleArgs(*args): etc.
Now, if I write instead of this def main(): for arg in
pywikibot.handleArgs(): etc. the result seems to be just the
same. I tried with valid global
and with
unique parameters as well. So, what is the
difference? I know the
theory that * means a variable width argument list, but
if I
omit it, the behaviour does > not change.
The behavior is the same if you run the script from the command
line.
However, using (*args) also allows you the option of running the
script from inside the Python interactive interpreter; for example,
if you were running "replace.py Foo Bar -start:!", then you could
"import replace" in the interpreter and run
<code>replace.main("Foo", "Bar",
"-start:!")</code>. This can be
useful for debugging, among other things.
