<0> and can someone explain this factory thing to me?
<1> sonium: What do you want to know?
<0> for what do I need it
<1> sonium: What do you mean by "factory thing".
<2> evening Jerub :)
<3> sonium: Factory design pattern. A constructor is visible to ONLY the factory. You ask the factory for an instance, the factory gives you an instance based upon what you specify.
<3> I'm not quite sure what its advantages are, but it's pretty easy to add on after the fact.
<0> ok
<0> then I just created a factory
<4> I'm confused.
<4> why is it visible only to the factory? that inplies that the system is not extensible.
<4> s/inplies/implies/
<2> that definition of a factory is inadqeuate anyway
<5> sonium: A factory is just something that builds objects
<2> I still dunno what it is :)
<2> now that's a better description :)
<5> (Screw design patterns!)
<2> in that case, most functions in the std-lib are factories that build an object
<2> eg: re.compile
<5> prologic, yep.
<2> no big deal then :)
<6> Hey dudes. What template engine would you recommend for web?
<2> we use factories all the time (though me not that much)
<2> Blackb|rd, I'm using kid and it's quite nice
<5> Bleadof, I've had good experiences with Cheetah.
<6> Brend, cheers, I'll give it a try :)
<5> (mostly)
<6> Well, it's always mostly ;)
<5> My only real grudge is that the placeholder syntax is slightly different in different places
<5> Which makes it a bitch to generate templates from code
<6> :/
<5> "Hello, ${name}" works. So does "#for name in $names". So does "Hello, $name". But "#for name in ${names}" doesn't
<5> So if your placeholder names contain, say, spaces, you're in trouble.
<6> Oh, ok.
<7> what would be the best two deadtree books(or pdf) to buy about python for a neophyte?
<7> not a programming neophyte but probably a scripting neophyte
<4> Keltor: diveintopython and learning python.
<7> Jerub: dive into is avail. in dead tree?
<4> yep.
<7> good deal
<8> hi - are there any python modules to load, manipulate and save pdf files?
<8> ps files, i mean
<7> aum: http://www.pugo.org/pyps/
<7> aum: no wait that won't work for you
<7> i just used that to CREATE them
<9> hello
<7> hello
<8> i need to load in existing ps files, and rotate/scale/move pages into other ps files
<9> im about to use python to manage my postgresql database, i have found 3 different wrappers: pygresql, psycopg, pypgsql.... which one should I use, your opinions please ? :)
<7> nemesis128: are you EVER going to use anything else?
<9> another DB ?
<7> yeah
<7> sqlite
<7> db2
<7> mysql
<9> mh, personaly, no
<7> ok
<9> SQLalchemy?
<7> would you ever give the code to someone else
<9> ;)
<7> who might choose to use
<7> let's say sqlite
<9> yeah that's possible
<7> possible enough to use a generic db entry method
<9> im open to any suggestions :)
<9> but my main pbm now is postgre
<9> and some features of postgre are not really portable to other db
<5> nemesis128, as I recall, all the PG wrappers ****, but in different ways
<5> One of them is impossible to make work on Windows but I can't remember which :)
<9> apparently Zope uses psycopg.. that's a good point for that one
<7> psychopg is probably best
<7> but umm
<7> a little birdy told me
<7> not to mix pg and python
<7> ;)
<9> why not ?
<7> like brend said
<7> all of the wrappers ****
<10> If I want to import a list of variables from a different file, how do I do it?
<9> because os sqlite soon into "native" python?
<7> i love sqlite
<7> for sooo many things
<9> i gave it a try, sure it's interesting..
<10> I'm trying to set a list of constants that should be consistent across my program.
<7> for non transactional stuff it's pretty sweet
<9> but im a postgre addict, cant imagine live without all the nice features it has
<9> i love python as well
<11> I'm the awesomest guy ever. Or something. I think I've finally managed to get my code to work.
<7> nemesis128: psycopg is probably your best bet
<7> best of a lousy lot
<9> mh..
<12> If anybody's interested in testing out my patch for a switch statement for Python: http://www.vector-seven.com/2006/06/10/python-switch
<9> your opinion about another/anything better than sqlite and different than postgre?
<9> mysql ?
<7> i personally use mysql and sqlite
<7> i'm using mysql 4.1 and one 5.0
<9> k
<7> i've got 34 4.1 dbs actually
<11> Does postgres allow you to put your outer joins in an arbitrary order? MySQL doesn't, and I was sort of surprised about it.
<11> Keltor: db servers, or just seperate dbs?
<7> CSWookie: there's 5 db servers
<7> CSWookie: 1 machine
<7> different settings depending on the db
<11> Ah.
<7> the 34 are mostly on 2 of the servers
<7> and just one on the 5.0 server
<7> basically a memcache and a non memcache
<11> I just (hopefully) got finished writing some code to turn a query in another format into SQL.
<11> I determined that I REALLY REALLY REALLLY wish C had closures.
<13> WTF is VSTS. :(
<13> Apparently, it stands for Visual Studio Team System.
<11> sanxiyn: MS's CVS?
<7> CSWookie: i think mysql 5.0
<9> thx for all :) ppl
<13> CSWookie: Yes, something like that.
<7> sourcesafe is their cvs
<7> i think it's more than just that
<13> Keltor: I thought SourceSafe doesn't work over network?
<7> probably more like trac
<7> sanxiyn: define over a network
<13> Keltor: Yes. It also has "work item" stuffs.
<7> yeah i think it's more fogcree/trac
<7> than cvs
<7> i am sure it can use sourcesafe or perforce
<7> maybe even subversion and cvs
<13> Keltor: I got the impression SourceSafe is more like RCS.
<7> sanxiyn: sourcesafe is complicated
<11> sanxiyn: Looks like it includes unit tests + deployment as well.
<7> mind you
<13> Anyway, CodePlex (MS version of SourceForge?) seems to use VSTS.
<13> So that's why I'm curious.
<7> i'd never wish VSTS, Perforce, CodePlex, FogCreek, or SourceSafe on my worst enemy
<13> Keltor: What do you mean?
<11> Keltor: MySQL 5.0 allows arbitrary ordered outer joins?
<7> CSWookie: i believe so
<11> Keltor: I've never used FogCreek, but I like JoelOnSoftware
<7> sanxiyn: they are all horrible products
<7> CSWookie: well his software is poo
<7> CSWookie: go read about it hehe
<11> Keltor: That's pretty cool.
<7> the vast majority of people FORCED to use it hate it
<13> Keltor: Ah, I see.
<13> Keltor: Is Perforce horrible? I don't think so...
<7> sanxiyn: well it's got it's good points and it's bad points
<7> it's heads above all the others
<13> (FreeBSD uses it, and it seems to work well for them.)
<11> Keltor: As I was writing the logic to make sure everything got sorted right, I was thinking about how this should be the RDBMS's job.
<13> FreeBSD kernel is now using CVS only for "distribution" purpose.
<7> sanxiyn: they are using perforce?
<13> Keltor: You didn't know?
<7> sanxiyn: i'd never heard that
