<0> I -am- a newbie when it comes to writing network type stuff.
<1> it may be overkill, but you could also look at twisted
<0> I originally wrote the app only with sockets.
<0> But the networking bits are a bit shoddy so I wanted to upgrade everything.
<0> Yeah. I've looked at Twisted.
<0> It looks nice functionality-wise. But I'd prefer to only use parts of the standard library.
<1> FWIW, there has been a fair amount of talk of deprecated asyncore at some unspecified future point
<1> *deprecating
<0> Hmmm...really...
<2> why?
<0> I wasn't aware of that.
<2> its useful.
<1> the thought would be to replace it with a small subset of Twisted, possibly
<2> no way mcmillen
<1> see http://www.python.org/dev/summary/2004-11-01_2004-11-15.html -- there are more recent threads (2005) discussing it as well
<3> jimbug: well, if you aren't familiar with select/poll stuff, you could look at the source code of asyncore itself for an example usage :)
<4> i'm having real trouble getting python to see svn. i have installed svn with swig bindings - do i need to do anything more on the python sside to get it to see svn ?
<5> kbingham: Where did you install the svn module? A typical cause is having multiple versions of Python installed
<5> kbingham: So find the directory with svn.so, or whatever it is called. Check the sys.path in your python. is the diretory there?
<4> i'm quite sure i've only got the one version of python on - jsut installed 2.4.2
<4> just running find | grep svn.so
<2> ignacio,
<2> i fixed the .py problem
<6> Not really.
<5> kbingham: Well, the module may not be called that. Look at when you did python setup.py install to see what it installed and where
<2> ignacio, well, it opens up in gedit now anyways
<4> erwin: is that a setup.py for subversion ?
<5> kbingham: a setup.py for Python is the equivalent of ./configure for C programs. It uses distutils to install a module.
<4> i've run python setup.py install for sqllite but not svn :) i'm guessing thats gonna be where my problem is :)
<5> Depends on what the svn python module is installed by
<5> BTW, on this system I run apt-get install python2.4-svn to install the SVN Python module
<4> i'm on slack 10.2
<4> no apt-get afaik:)
<7> How to check if a variable has a sequence type?
<5> Depends on how permissive you want to be.
<5> You could try iterating over it for example, or indexing it.
<7> I want an argument that can be one scalar, or some sequence of scalars.
<8> I need a little tutoring over here, I'm using this example http://fragments.turtlemeat.com/pythonwebserver.php as my basic http server, and I want to output variables from a simple script to it, but the script is a while loop... so it blocks execution of any response from the webserver
<4> effectively i'm trying to get trac running so i'm following http://projects.edgewall.com/trac/wiki/TracInstall
<8> is there a way to start it as a subprocess or something so I can p*** vars to it, but the while doesn't block it from running properly?
<5> halley: Note though that strings are sequences too.
<7> Erwin, yeah, this is ints.
<9> halley, why do you want that?
<5> halley: So you could also explicitly check for type, i.e. using if isinstance(foo, (int, long, float)): ...
<5> halley: Alternatively you could declare your function as foo(*arg) and then could call it as foo(1) or foo(1,2,3)
<9> Either require a sequence and let people write (5,) if they only want one, or provide two functions, one for a single scalar and one for a sequence
<9> Magic is usually not a good idea
<7> Erwin, the latter looks better.
<10> does any one take part of developpement of an open source ERp called TinyErp
<11> wots an erp?
<7> Brend, even the creator of python things (5,) is ****ing ugly.
<7> thinks
<9> I think so too, but at least it's explicit
<5> halley: note that that works best if you call your function with literal arguments. If you then need to p*** it a list you got from somewhere else, you'll need fun(*theList) to expand it into arguments
<10> dobson, http://tiny.be/
<9> dobson: Something for which large companies pay vast sums of money to be gradually destroyed
<7> Erwin, I see. I know it's not like perl where lists are distinct from arrays, and that's a good example of it.
<10> Brend, yeah it's a way to view the thing :)
<5> halley: In Python, everything is a reference and references are automatically dereferenced
<8> I want to output variables from a simple script to a built in webserver, but the script is a while loop... so it blocks execution of any response from the webserver, can I make a subprocess or something so that the while loop is not blocking the operation of the webserver?
<5> What is it doing in the loop?
<8> Running a pygame display window that updates a timer
<1> try looking into module "subprocess" or os.popen*
<9> Or Twisted!
<5> rofl-waffle: Well, maybe pygame lets you integrate its loop with events from web servers
<5> rofl-waffle: But yeah, I think twisted has a pygame loop
<8> oh ok, thanks for the pointers, I'll go try and figure it out :)
<5> So with twisted you could -- for almost free -- get a web server, ssh server, ftp server and name server integrated into your app
<9> I am terrified of any game which includes a nameserver : )
<1> me too :)
<12> I guess a game with a ssh server is more scary
<5> Well, if it was a MMORPG you could use it to give each player his own subdomain :-)
<9> Die
<13> you too , hi :)
<14> I'd like to get the best textual representation of current function/method in the code. What should I call to get it?
<5> Define textual representation
<5> And what's the purpose of this?
<15> which module provides a method for getting the size of a directory?
<1> tuxipuxi: os.listdir?
<5> There's nothing like "du"
<15> oh
<5> If you want to add up the sizes of all files, you'll need either os.listdir and os.path.getsize, or os.walk
<5> The latter if you want recursion
<15> so best way is to use popen and get the output of du?
<1> depends on what you mean by "best"
<14> Erwin: method M of cl*** C wants to syslog the message "Packet loss", so it calls log("C:M:: Packet loss"). I wish the log "header" -- C:M:: -- to be dynamically retrieved by some call so I do not need to rewrite the log messages when adapting the code to different methods.
<1> less portable, but far easier to code, yes
<2> stain, Are you there?
<2> stain, Please say you are :P
<15> mcmillen: yes doesn't have to be portable, just needs to run on linux
<2> question.
<1> then popening du is probably easiest
<5> Tuttle_: check out sys._getframe() then, but that's an internal C Python function
<2> what things could i even use the call stack for
<2> Erwin, inspect.getstack is better
<2> er
<2> inspect.stack
<1> traceback.extract_Stack
<14> I just found out that inspect.currentframe() returns the same object as what you're proposing now.
<5> >>> inspect.currentframe is sys._getframe
<5> True
<14> :)
<15> mcmillen: ok thanks
<2> Tuttle_, inspect.stack(2)[0] == inspect.currentframe(), methinks
<1> use inspect or traceback.. got a great idea to use functions that start with _, as they may go away or change interface on you
<1> *got->not
<2> not*
<2> yeah :P
<5> tuttle_: Are you going to disappear among a small tornado of newspapers now?
<2> Erwin, very funny.
<14> Erwin: I'm going to disappear and never existed even when I'm given a medal. ;-)
<16> are there any source-level debuggers for python that look more like the visual studio debugger?
<4> do i have to make / install SWIG separatly or does it come with python / svn /
<16> e.g. with a window where you can add variables to watch
<1> it's separate
<17> hi
<4> is there an easy way to see if i've already got it installed?
<4> its not a command as such is it - more of a library
<17> I have a strange sort problem
<5> kbingham: It's a separate package
<17> i know there is function called sort() which takes even a function which tells it how to compare
<4> ok - just downloaded - gonna install it now
<5> kbingham: It's a generic tool for wrapping all sorts of C/C++ libraries to Python , Perl and many other languages, so it's not Python specific
<17> the compare function needs 3 return values -1,0,1
<17> and 2 arguments
<2> luh: yes
<5> luh: If you are using python 2.4, it is far better to use the key argument instead.
<5> luh: e.g. l.sort(key = lambda x: x.someAttributeToSortOn)
<2> Erwin, what is that?
<17> the problem i have is that my compare function doesn't know yet how it is supposed to sort, but gets the information during the running of the program
<17> (it should be able to sort in different ways)
<17> but i have no clue how to do that
<5> luh: You can either make a function that checks that how to sort varialbe and acts differently, or several specialized functions if there are only two ways
<5> def sortSomething(): ...
<5> def key(item): if sortOnFoo: return item.foo else: return item.bar
<5> l.sort(key)
<5> well, l.sort(key = key)
<17> ?
<17> i want to sort objects from a cl***
<17> this cl*** has 4 values it can be sorted on
<5> And? No matter where you are doing this from, your compare or key function should find the sorting key from somewhere and apply it
<5> If the values are attributes, the sorting key could be the name of the attribute
<5> e.g. l.sort(key = lambda x: getattr(x, self.sortingKey))
<5> where you before did a self.sortingKey = 'name' or 'age' or whatever
<18> I'm trying to make a cl*** that extends __builtin__.str, with keyword arguments in the __init__() method, but it is complaining about "'gapsize' is an invalid keyword argument for this function" -- is this a problem in the way I'm defining the method or a way I'm calling it?
<5> LazloFruvous: You'll need to override __new__
<18> Erwin: oh...why?
<18> I've never extended a built-in type before... are there some docs about it?
<5> LazloFruvous: Immutability of string objects
<17> Erwin, - it sorts 4 values default would be style, artist, album, title (it's a tag cl***)
<14> Ok, but I still can't get the cl*** name from the frame...
