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.
