its a hash
<keyvan>
never seen that either
<keyvan>
the colon in front, seems new to me
<aces23up>
one sec I will drop more code.
<keyvan>
reminds me of symbol to proc
<otters>
it's a symbol
<otters>
:@args is a symbol
<yfeldblum>
aces23up, looks like it should work to me
<aces23up>
yeh i thoughts its the change from 1.8 to 1.9
<keyvan>
oh thanks otters
jorge has quit [Remote host closed the connection]
<aces23up>
ok I drop some more code.
<seanstickle>
It's a symbol, but who uses "@" in a symbol?
<seanstickle>
It looks like an instance variable masquerading as a symbol
<keyvan>
seanstickle looks like thats how u use instance_variable_defined
<keyvan>
*?

seanstickle, um ... in ruby, if you want to talk about parts of your programs by name (names of methods, names of instance variables, etc), we use symbols...

this bit of code just broke when switching to 1.9
<keyvan>
my only guess was that self was different so #instance_variable_defined? was acting on a different instance. but you're hitting that method right after another, so the instance should not be different… so i am confused now too
<aces23up>
was working fine on 1.8 using instance_variables.include?('@args')
<aces23up>
yeh weird.

mehlah_ has quit [Ping timeout: 244 seconds]
<aces23up>
seanstickle ok its seems to be working.. my error was weird.. but what actually seems to be broken, is farther up the chanin.. as @args is not a hash but an array of hash now.
<keyvan>
but is true in the puts…. weird.

macer1_: how do you get the argument names from *args? use opts = {} and call like MyClass.new(arg1: 2, arg2: 40, ...)
<macer1_>
eee
<aces23up>
i can only think cause I pass *args around further up.
<macer1_>
I want :user => "asd", :password => "asd" style
<aces23up>
is there a diff between the way the splat operator works from 1.8 to 1.9?

whatever
<macer1_>
now the respond_to part

fowl: thx
<macer1_>
I mean *args
mehlah has joined #ruby

*args traps everything in an array, opts={} expects you to pass a normal value, or a hash, or an open hash
<macer1_>
ah

Hello. I'm having a really tough time figuring this out. I want to access class variables created in a superclass, by the subclass. I can't seem to get that to work. So I tried using mixins and include, but that doesn't seem to work either.
<bnagy>
unless you have accessors set up, which would make it a lot less ugly
<jayblack>
I mispoke, I meant I'm creating the class variable in the subclass, and I want to access it from the superclass.
<jayblack>
I have a Common < Test::Unit:testCase which is supposed to hold tests that are common to a set of classes that are intended to subclass from Common.
ecksit has quit [Remote host closed the connection]
<jayblack>
e.g. Common < Test..TestCase , the TestPA < Common, TestNY < Common, and so on, and Common would have a test_no_id, which is expecting a class variable named @state
nguyenduy has quit [Read error: Connection reset by peer]
<bnagy>
ok you've lost me
<burgestrand>
class variable is not the same as class instance variable, jayblack are you using @@var or @var?
<bnagy>
you want a superclass to poke around in its subclass? :/
<bnagy>
that's gross, but you could look at the inherited methods
<jayblack>
class variables, @@ state.
<jayblack>
Not really, that's generally bad mojo.
<bnagy>
that's even more gross
<jayblack>
But I have a pile of 20 or so test case classes that all have a "test_no_id", with a single variable name.. the state.
<burgestrand>
I don’t see the problem. When inside the method in test_no_id from Common, you are infact not only a Common, but you might be a TestPA or TestNY.
<jayblack>
I'm trying to strip that redundancy out to something common, so as I do another.. say 30 test classes, I don't have 50 common
<burgestrand>
The variable you want to access is already yours.
regedarek has quit [Ping timeout: 245 seconds]
<burgestrand>
You could just as well make it a method and override it in subclasses if you want as well.
rd34 has joined #ruby
sevvie has joined #ruby
<jayblack>
That seemd like the right approach, to make a Common class with the commoin test methods, then subclass the inviddual states with their tests.. but the Common class needs to know which state it is, so that the generic tests can be run for that particular state
<bnagy>
maybe I am pre coffee but that makes no sense to me at all
<jayblack>
That's basically what I'm trying to do.
<jayblack>
I noticed, by the way, that though I wrote 5 tests, test::unit says its running 7 tests
techsurvivor has joined #ruby
<jayblack>
I would have expected 6 classes to run, not 7
<jayblack>
pardon, 6 tests, not 7.
<jayblack>
if I subclass SubClassOne and SubClassTwo off of Test::Unit::TestCase, and comment out the common class, it works as expected.
Goles has quit [Quit: Computer has gone to sleep.]
<jayblack>
I also tried making Common a module, and include/extend, but I ended up with the same problem of getting access to the class variables.
heftig has quit [Ping timeout: 245 seconds]
JohnBat26 has joined #ruby
<jayblack>
I'm not picky on how I do this, I just want to be pull out the redudundant methods for all my test suites, and in one way or another include them, so that I don't have 50 redudnant copies of generic tets.
<burgestrand>
jayblack: I suppose using a module instead of subclassing would be the preferred way here, or your Common is also run as a test class.
dhruvasagar has quit [Read error: Connection reset by peer]
<burgestrand>
Perhaps there’s some way to turn that off, I don’t know, don’t use test unit.
<jayblack>
That was where I went second. When I make common a module and nclude it, the methods can't seem to see the class variables, though

adamkittelson has quit [Remote host closed the connection]
cpruitt has quit [Quit: cpruitt]
<jayblack>
and when I use extend, Test::Unit doesn't run the tests in common at all
<burgestrand>
jayblack: it’s probably as a result of using class variables instead of class instance variables
<jayblack>
When I use class nstance varaibles, they show up as nil.
Rezwan has quit [Read error: Connection reset by peer]
<jayblack>
(versus as class variables, they show up as unitialized)

bradhe has quit [Remote host closed the connection]
<burgestrand>
Yeah, class instance variables are not the same as instance variables. If you set them in the class scope, you must access them from there as well, like this: http://ideone.com/AZ753

Is it possible to access class variables or instance variables from within module methods that are included ?
<burgestrand>
jayblack: class variables are crazy, but you can access instance variables like usual, and you can still ask your class for its instance variables.
<fowl>
yes for instance vars, class vars i have no idea because they're gay. you should avoid them or your code will get aids.
<burgestrand>
I don’t see a solution to this using class variables. I don’t know why you are so keen on using them.
<jayblack>
Ok, and to reaffirm, @variable is an instance variable
uris has quit [Quit: leaving]
<burgestrand>
jayblack: yep, but it can have different scopes.
<fowl>
burgestrand: we need to put a warning in the topic: class variables will give your code AIDS

That's offensive

AIDS isn't that nasty

regedarek: for counting use something like this: array.count {|h| h[:asin] == '1403975078'}

regedarek, also use .flatten on the first array, you have an array in an array without needing it
<shevy>
always try to make the data structures as simple as possible

it is "rack does not accept a string in 1.9.3 as 3rd return value"
<apeiros_>
that's two quite different things.
andrew___ has quit [Remote host closed the connection]

the 3rd return value must provide #each. in 1.8 that means you can pass a string. in 1.9 you can no longer. that does *not* mean rack does not work in 1.9 anymore.
<apeiros_>
hekin: and no, rails works fine with rack and 1.9

hm, yeah, I guess #rubyonrails. it seems to me that you get a head request and either your app or a part of the rack stack incorrectly returns a string instead of something that responds to #each

Hm, trying to think of the most graceful way to generat a Time object that represents 07:00 UTC today, relative to whenever it's generated.

E,g, if run tomorrow, it'll give you a Time object that's 07:00am on Aug 2nd, 2012 etc.

workmad3: let's say my entire idea is to mimic an Apple. Then I named my module Apple with some constants and I'd create a classes called Size, Worm, Quality and so on. How do I create an instance of Apple then?
<Harzilein>
hi
<workmad3>
_bart: you don't
<apeiros_>
_bart: you'd have a class Apple, not a module
<apeiros_>
and then you'd do Apple.new
<workmad3>
_bart: because... and this is surprising since I already said it... you *can't create instances of modules!!!*
<workmad3>
_bart: you create instances of classes, not modules
<Harzilein>
is there a nice gem that allows me to replace huge static case or elsif with something dynamic?
<_bart>
but the module was great for storing the overall constants
<Harzilein>
+a
<apeiros_>
_bart: you don't have to change that
<workmad3>
_bart: you can do the same thing in a class
<_bart>
workmad3: then if I only use classes, where do I stick the overall "settings"/constants
<Harzilein>
it should at least make monkey patching possible, a dsl would be nice as well
<_bart>
but I have multiple classes

_bart: just replace `module Apple` with `class Apple`

JonnieCache: there used to be a patched ruby that helped sandboxing ruby, and loads of resources about it as well. But the proper solution would probably be to make the filesystem read-only and allow the bot wreak havoc if necessary, but still restart every N minutes.
<stenno|work>

<stenno|work>
yes, run the bot in a vm
e4r has joined #ruby
<JonnieCache>
yes but then theres the network
<JonnieCache>
youd have to put it behind some separate firewall
<stenno|work>
do you really../
<JonnieCache>
far too much work just for a bot
<burgestrand>
Naw, no need to allow any outward traffic at all except for IRC.
<jrajav>
Am I missing something here? Why not just make the ruby interpreter separate from the bot itself? The bot doesn't need to be the same instance as the interpreter
<JonnieCache>
yeah but how are you going to disallow it? considering that we have to assume the bot has root access?
<stenno|work>
2 minutes in iptables :P
<jrajav>
That way each snippet is completely separate from any other one
<JonnieCache>
stenno|work: im assuming that the bot would be able to disable that if its running on the same machine
<JonnieCache>
privilidge escalation is pretty easy if you have local shell axx
<burgestrand>
jrajav: yup, probably the saner solution but would still need to kill/restart the process in case somebody hangs it.
<stenno|work>
JonnieCache, :)
<stenno|work>
no prob if you are in vm sandbox though

make system calls as you like...
iamjarvo has joined #ruby

yeah if it was inside a VM with the firewall policy set from outside that would be OK I guess

burgestrand: Some kind of timeout would probably be a good idea though
<stenno|work>
jrajav, do eet then :D
<burgestrand>
jrajav: yep, and for CRuby a thread can block the entire interpreter as well so it doesn’t help much except for being able to run several snippets at once.

Think you misunderstood… I just meant the master bot (which may not necessarily be in Ruby itself) not blocking for a single snippet, whether it does that with threads or otherwise

The whole point of running the Ruby interpreter separately would be so it couldn't hang the bot

do_something if !options[:run] || (options[:run] and this_might_fail)

is there a way to have rescue handle only errors defined in a specific module/class ?
<mascool>
I mean something like Module::Errors instead of listing all the possible errors one by one
cjlicata has quit [Remote host closed the connection]
<burgestrand>
mascool: one way is to have all your errors in that module/class inherit from a common base error class, say Module::MyErrors, and rescue that
phinfonet has joined #ruby

mascool: define a module with an === that maps to those errors
<burgestrand>
mascool: it’s probably the cleaner way, otherwise you could do what banisterfiend says

If there's a hirerachy in your exception, you can better select which exceptions to rescue depending on the case, without being affected by the addition of a new one

Ah, yes.

You can add an empty module and include it into your exceptions, and then rescue that.

I realize its usually best to just right good readable code and leave the rest up to ruby's garbage collection algorithm but i'm wondering if someone might shed some light on this question. Let's say I set an instance variable to be an object that I've created, this object has its own objects as well and uses self as one of its parameters (self is a Gosu window). Is it better to reset my object or create a new one?
<saneshark>
*write
<shevy>
saneshark reset
<shevy>
and write the class in a way as to allow a re-use of it
<saneshark>
shevy: thanks, and this is what I thought, can you explain why this is more efficient?
<shevy>
I dunno if it is more "efficient"

sdwrage has left #ruby [#ruby]
<shevy>
I dont think it makes any difference because Board.new will make a new object which occupies the same space as the old object does
<fowl>
saneshark: you're only going to have one board, i thought you wre asking about game objects
<saneshark>
shevy memory usage I'm pretty sure i can just trust the garbage collection on, especially since its an instance variable
chrisbolton has quit [Quit: chrisbolton]
<saneshark>
fowl: my board class has a lot of additional game objects which reference self as well
<saneshark>
well, @window in that case
<saneshark>
it's tic tac toe, so technically @board only has three additional classes, Grid, Cross, Circle
<saneshark>
normally i wouldn't care about this, but its the reference to self that is throwing me… i wonder if the garbage collector will assume that the previous object still needs a pointer since "self" has not been destroyed
<fowl>
one thing chingu does is set $window = self when window is created that way you dont have to pass it to all your objects
<fowl>
and its fine in this case since gosu won't run two windows in the same process
<saneshark>
fowl: chingu is unnecessary overhead since i'm not using physics in this game, it's just aboard game
<saneshark>
i hear you though, i actually like fidget a lot too
<saneshark>
fidgit rather
<fowl>
chingu doesn't include physics, it has basic collision detection, but all of the options for game object are completely optional

<saneshark>
hmmm i kind of like that Gosu is so low overhead though
<fowl>
saneshark: in your window initialize set $window = self so you dont have to pass it around a lot
<Spooner>
Well yes, but you don't have to use everything in chingu/gamebox. If something doesn't suit you, then keep it simple and roll your own.
<saneshark>
fowl: is that a class variable though?
<fowl>
no, global
tatsuya_o has joined #ruby
<Spooner>
Global. You could set it up using Window.instance (class instance variable) if you prefer though (and fear globals).
<Spooner>
Passing a unique value around everywhere is a bit pointless.
<fowl>
this is the only instance i would use a global because you can only have one gosu window open
<Spaceghostc2c>
saneshark: Most usually.
<Spooner>
It should really be Gosu::Window.instance or Gosu::window, but noone bothers with that, which is a shame. Usually people just use $window.
<saneshark>
fowl: good point, and as a result wouldn't need to worry too much about memory management, but if that's the case i could just set @window globally myself why introduce a new gem to do something so trivial?

But self is the object itself, so it doesn't reference it per se.
