given my 1 hour of ruby experience, it seems that the posted code doesn't actually do anything :p
<jimbow>
not yet
<jimbow>
is there a way that i could get my brain tested
<jimbow>
people say i'm a "genius" but i feel like i'm fucking retarded
<lunaticedit>
"def" defines a method, so your example has two methods defined
<RubyPanther>
memory sucks
<lunaticedit>
correct me if i'm wrong, but you don't have to prefix variables with @ unless you plan on making them class members
<jimbow>
oh
<RubyPanther>
where the heck did I put my manual?! rubber duckiiiieeeeeee!
<lunaticedit>
(@@ prefix makes them the equiv of STATIC, as in, they are shared by all instances of said class)

i hate coming in here with nonsensical questions but why would i want to make it a member of a class?
<lunaticedit>
that's a question for the ages
<jimbow>
i don't want to waste anyone's time either... i'm trying my best to learn programming, but it's so freaking hard
<lunaticedit>
I like to group my logical pieces into classes, you could technically just write procedural code with no classes
<RubyPanther>
wtf is a member?
yfeldblu_ has joined #ruby

But for example, I have a class that represents a single line of text, and another class that represents a collection of said lines

Where is a good irc chat I can go too.
<jdjd555>
To ask where I can download tinder app on computer.
<ari-_-e>
jimbow: this is irc, we're all wasting our time :)
<lunaticedit>
#ubuntu if you like scrolling text
<jdjd555>
Since it requires an ipad or android devicec.
<jdjd555>
And I dont have one?

<lunaticedit>
jdjd555: You can use an android emulator or iPad emulator (if you're on OSX)

on OSX you can run iphone/ipad emulator via the stuff installed with xCode, on the "winders" you can download the android emulator stuff from google

no need to return true on last line of valid method
<OffTheRails>
return is implicit
Es0teric has joined #ruby
<lunaticedit>
I thought it implicitly returns the value of the last expression
<lunaticedit>
which would be false in that case
<OffTheRails>
yes, that's why you don't need to "return true"
<OffTheRails>
just "true" will do
<lunaticedit>
OH
<lunaticedit>
dur
<OffTheRails>
same with SourceFile, use attr_reader and break up your initialize method into multi-lines

parseLine should be parse_line. If you want it private, mark it as such
<lunaticedit>
yup, symantics, gonna take a while
<OffTheRails>
sadly, access control is not at all secure in Ruby
toastynerd has quit [Remote host closed the connection]
<lunaticedit>
yeah i was originally going to make it private
<lunaticedit>
but as i read up i was like "ehh.. nah"
<OffTheRails>
for example, you can make the method private, hide it all you want, but you can still call it externally
<lunaticedit>
but the important thing is you implicitly ~knew~ it was meant to be private
<lunaticedit>
this is why i like _ prefixing on privates ;)

you said "sadly"
<OffTheRails>
yes, because it would be nice
<ari-_-e>
why?
<OffTheRails>
well, because if I want to mark a method as private, I want it to be private
<ari-_-e>
OffTheRails: if I want a variable to contain a specific type, I want to be able to say that
<OffTheRails>

OffTheRails: encapsulation isn't about security, and private/public/protected isn't about making things impossible to find
hgl has quit [Ping timeout: 245 seconds]

is 'find' not in the same arena as access control?

they're more about specifying an interface

It articulates why I feel iffy with encapsulation in Ruby. But that's fine. Who cares. What's important is why these choices are made. There's tradeoffs at almost every level

It's confusing as hell but I will go for it, from what I SEE

Foo is the class
<shevy>
yes

Foo.new makes a new class
<Freddan962>
Jhass, Shevy: I am trying to write a content manager for my game. It should store all the content (objects) in a grid system. The total 'world' size is 640 by 480. Each grid should represent 32 pixels. I am trying to think of a smart way to access the content in a grid. Perhaps a multidimensional array? How would you do it? Would be nice if you could access the content by content[x][y] => array of content at grid x, y
<shevy>
yes
<noob101>
then um, .foo is the method
<shevy>
yes!
<shevy>
now you know the right order
DaniG2k has joined #ruby
<noob101>
.foo puts @foo I think
<shevy>
what is left to do is to track the value of @foo
<shevy>
well, there is no puts in his code
<jhass>
noob101: re Foo.new, almost, it makes a new instance of the class, also known as object (probably right in your head, just wrong terminology)
<noob101>
@foo will always be the last value assigned to it right?

you again ignored scope
<shevy>
you will first need to understand scope before you should continue
<jhass>
Freddan962: array of array of arrays should be fine for a first iteration, later you may want to implement custom classes that provide the [] and []= methods for similar access
Hanmac has joined #ruby
<shevy>
noob101 if it helps you, you can have multiple @foo
<noob101>
multiple instance variables with the same name and different values, how does that work out?
<jhass>
noob101: so local and instance variables, in contrast to global variables, are bound to certain scope. Different statements create new scopes and there are different types of scope, for example class scope, instance scope and method scope
<shevy>
and is thus valid only within its scope
<shevy>
so if you have:
<shevy>
class Foo; @foo = 5; end
<shevy>
it's different to
<shevy>
@foo = 5
<jhass>
Freddan962: yep
<shevy>
noob101 because they are legit only in a respective scope, and out outside of that; other languages have that as well

<Freddan962>
noob101: You might want to look into some Ruby documentation or tutorials.

Hello

To improve my Ruby skills, many suggest reading a gem code.
<sheperson>
Can you suggest a simple enough gem for this?
enebo has joined #ruby
jokke has quit [Remote host closed the connection]
<shevy>
sheperson no but build your own gem
Neomex has quit [Quit: Neomex]
<shevy>
first, write some code
<shevy>
then you must write one file called .gemspec
<shevy>
afterwards you can do: gem build *gemspec
jokke has joined #ruby
<Burgestrand>
sheperson: I would suggest you don't treat it as reading a book necessarily. Make a habit of reading the source for things you use, especially for debugging.
<jhass>
#ruby presents: "shevys masterplan to world domination". Step 1: write a gem. Step 2: ???. Step 3: Profit!
s00pcan has joined #ruby
<centrx>
I think sheperson wants to read some existing high-quality idiomatic code, which is a good idea.
<sheperson>
centrx: yes
<Burgestrand>
sheperson: sinatra is small enough to start digesting, but it tends to be easier to read code if you know what you're looking for.
<centrx>
Sinatra that's a good idea
<sheperson>
Burgestrand: excellent
jokke has quit [Client Quit]

sheperson, Also take a look at ActiveSupport. It mostly consists of utility methods, so there are small independent chunks making it easier to understand what is going on

sheperson, (ActiveSupport is part of Rails, but reading the rest of the Rails code would be...complicated and unhelpful)

and you guys burden him with activesupport and sinatra :(
<sheperson>
Infact I got the the Rails source, and it confused me

ActiveSupport is simple. You can read one method from it, say Hash#slice, and get value out of that
<centrx>
not saying read the whole thing cover to cover
<jhass>
Freddan962: so you want to assign one of the objects to each tile?
<jhass>
(tile = 32x32 pixel sub-grid thingy)
<Freddan962>

centrx: .map(&"%s=%s".method(:%)) is nearly similar to .map{|a| "%s=%s" % a }

Hanmac: Not sure whether your use of the char literal, or the implicit parameters to the block, are worse!
<Morrolan>
Of course, method(:%) might win an award, too. :P

Freddan962: Ah, so that thing should be a subview of the whole thing? I'd probably just keep offsets for that and filter the objects with that

I want to divide the game 'screen' into cells which are 32x32 so the ContentManager can keep track of what is where and increase the effeciency of my collision detection calculations.

<Freddan962>
Jhass: No, unlimited objects. But, content manager keeps track of in what cell of the screen these objects are in.

you mean "Foo" + arr ?

Ok, now lets do it this way:

s00pcan has joined #ruby
<Freddan962>
arr = [Objectinstance, AnotherObjectInstance, ThirdObjectInstance]; objects = [], objects << arr.foo. Objects should contain the contents of arr, but not the arr array.
<Freddan962>
Sorry if I am confusing you :P
<jhass>
objects.concat arr
cherry_lin has joined #ruby
<jhass>
or objects + arr if you want a new (resulting) array

there are some minor scoping diffrences :u
MrSamuel has quit [Ping timeout: 252 seconds]

but they should not trouble you
<Freddan962>
centrx: But I am not looping over elements in an array. I am looping over space in my array, which does not have to contain objects.
<centrx>
Freddan962, Ruby converts for..in to #each internally, and #each is idiomatic
jokke has quit [Quit: WeeChat 0.4.3]
<benzrf>
idiotmatic :^)
<Morrolan>
Freddan962: I assume object.x is a float. And a float, divided by an integer, yields you a float. Hard to tell the definite cause, without knowing what kind of objects we're dealing with, though. :)
<benzrf>
Freddan962: are you a python guy, or a java guy?

Freddan962, It was just an example. Whatever for..in is used for, #each can and should be used instead

Morrolan: Your assumption is correct :D

hey, I'm new to Ruby and having a problem. I'm trying to install SproutCore under JRuby. to do so, I'm doing "gem install sproutcore", pulling it from rubygems. however, this is trying to install thin, which doesn't work under JRuby. I've looked at the gemspec, and it has a section where it conditionally picks whether to use Thin or Mongrel. how do I tell gem to read the gemspec properly?

Freddan962, The value will no longer be attached to the variable, and the garbage collector will clean up the memory on its own time, if it is no longer referenced by anything else
<Freddan962>
centrx: Would this way work to not point the variable to a new location in memory with the same data? (@@images = images if @@images.nil?)
<centrx>
I'm not sure what you mean
<Freddan962>
centrx: Would this piece of code make so the class variable never gets set to another value, other than what it first was assigned?
<centrx>
what is "images"? it's not @@images
<centrx>
is that variable defined earlier somewhere?
<centrx>
oh I think I know what you mean
<sandbags>
Freddan962: the answer is yes, you could also write it as @@images ||= images
supermarin has quit [Ping timeout: 240 seconds]
<Freddan962>
sandbags: Always wanted to ask - what does ||= 'mean'?
<Burgestrand>
Freddan962: avoid @@-variables if possible, and use @-variables instead. @@ is, in the majority of cases, not what you want.
ringarin has quit [Ping timeout: 265 seconds]
<sandbags>
Freddan962: it's a short hand for @@images = @@images || images
<Freddan962>
Burgestrand: I only want my loot class to get the images once from the resourcemanager. Thats why I thought it was a good idea to use a class variable :P
<Burgestrand>
Freddan962: do you have experience in any other programming language?
<Freddan962>
Burgestrand: C++
toastynerd has joined #ruby
<Burgestrand>
Freddan962: hehe, unfortunately I don't have experience with C++. Either way, I believe you have misinterpreted the difference between @-variables and @@-variables. @-variables can also be used on the class level.

well, I've looked at the wordpress architecture, it's not bad. but the idea that you have a separate backend from the frontend, and other things..it's just doing too much

It worked out in the end though. Women flock to me when I start telling my WooCommerce stories at parties.

Senjai: pretty broken responsive design too
<imaleaf>
it just doesn't make sense--if one needs to make an application, why not use a framework. and then we could create blogs and wikis that are all gems/composer modules
<lunaticedit>
If there's one thing i've learned in my years of coding, its that abstraction for the sake of abstraction is both a waste of time, and a mistake
<imaleaf>
instead of having these massive beasts that people try to force to be something else
<Senjai>
EatMulti: The second WP needs to be more than a blog, its time to make an application
<EatMulti>
Senjai: precisely, be glad you don't have to look at the php for it
<lunaticedit>
If you write properly designed software that has low class coupling, its easy to add abstractions when needed later

Yeah, the problem is some people take that idea to Abstraction == Not getting real work done.

If you actually know what you're trying to do, the implementation is guaranteed to be trivial.
enebo has joined #ruby

exactly, which is what my job is -- to take the requirements, and turn it into something a person can actually implement
<imaleaf>
RubyPanther: well isn't that the idea? implementing for an output, because ultimately what we are trying to get is output? rather than thinking about problem
<RubyPanther>
imaleaf: if you start out knowing what output you want, you're probably not asking, "what output should I want?"
<imaleaf>
hm
<RubyPanther>
What is the real (human) problem, and what is the nature of the problem domain? What outputs would help the human the most? That is sooooo much more important than the stuff people usually get caught up in, like "what output did the human ask for?"
<takemikazuchi545>

Freddan962: ...you just told your computer "run steamcmd.sh, in the root directory of my machine, even though there is nothing but directories in root, and what I want to do takes place much lower in the filesystem". sh steamcmd.sh would be correct. your issue is within steamcmd.sh itself.

ktosiek has quit [Ping timeout: 245 seconds]

RubyPanther: I mean, when creating functions, you are solving individual -pieces- of a problem. and they need to be strung together and work toward solving the larger one. so designing a function toward a specific output that you need, a result, makes sense

<RubyPanther>
imaleaf: sounds like a random pile of methods to me, not a well designed system

a method should not have any idea of what the larger problem is, that implies excessive coupling

lunaticedit: well isn't a certain amount of coupling necessary? methods within a class are working towards a major function
<lunaticedit>
i try to avoid that where possible
<lunaticedit>
because when you have a function that relies on an external variable, you can NEVER garuntee a state from the perspective of that individual function
<imaleaf>
I mean within a class
<lunaticedit>
even within a class
<takemikazuchi545>
As a junior developer the amount of coupling vs. decoupling(like dependency injection) is really difficult when I'm writing a class.

<lunaticedit>
so that'd be where you do the 'steps', BUT only in that one place, each indivdual step should not know about the other
<takemikazuchi545>
The big issue is that the data is often really dirty, so I want to be able to override a step.

'override' meaning
<lunaticedit>
when you talk about overrides, you start getting into the realm of dependency injection, which can get real messy real quick

well for each iteration i'd validate the row, and use that to determine how to map

where mapper.genreate would return class A or class B that will map normal style, or with some custom error correcting logic
pareidoliax has joined #ruby
MrSamuel has joined #ruby
<lunaticedit>
that way you have no 'override', you have one function (isvalid) that determines if you can do a normal map or not, and then a specific implementation based on either situation. There is no stateful logic at that point, and you get to stay in boxes

It is high quality software, I don't think I've seen a new feature in over 10 years. That is as it should be. Figure out what it is supposed to do, and make it do that. New features are admissions of past failure. Admit failure, but don't fail all year every year like firefox is doing.
<pontiki>
oh crikey, now we have orthodox ruby?
Xeago has joined #ruby
<shevy>
RubyPanther I can't compile it anymore
<n_blownapart>
pontiki: I forget the term they used...
<pontiki>
maybe "idiomatic"
<shevy>
n_blownapart "not sane ruby"
<centrx>
Ruby with the Filioque
<shevy>
n_blownapart the real way to reach idiomatic ruby is to write a lot of code
<RubyPanther>
Orthodox Ruby ensconces the UNIX philosophy, and that giant method that does a bunch of different things should be burned at the stake! Heretic!
<n_blownapart>
shevy: well these problems I find interesting.
<ashp>
idiomatic ruby is to make a terrifying metaprogramming mess for the next maintainer :D
<RubyPanther>
It looks like it was ported straight from Perl.\

if it is not your code, why are you staring at it

In Ruby we try to avoid punctuation unless we can string a bunch of punctuation together in a row so it looks funny.
<segfalt>
(n % i).zero?

<n_blownapart>
ok is the second example any better ?

n_blownapart: which is the part you don't understand?
<RubyPanther>
n /= i is syntactic sugar and means n = n / i
<RubyPanther>
which is why nobody does that, instead they say m = n / i

<n_blownapart>
The program does work, after all, that much I know.
<RubyPanther>
n_blownapart: 5 and 6 have the same meaning as they would have in an algebra class
<Nilium>
in haskell ::=-!!#^== means equals

so you're squaring the lowest prime number to begin a loop that computes higher factorials or somesuch?
<n_blownapart>
RubyPanther: ^
mercwithamouth has joined #ruby

so in pseudocode, while the ponies still have ugly tails, trim them. In Ruby: while pony.tail == :ugly do ; pony.tail.trim! end

smathieu has joined #ruby
<RubyPanther>
it is really awful code though, for example: sqi = 4 # square of i
<benzrf>
god damn
<benzrf>
shevy: <3 pone
<RubyPanther>
but then later at the end of the loop: sqi += 2 * i + 1 # optimized version of sqi = i*i
<Nilium>
pony.tail.trim! while pony.tail.ugly? # the correct pony tail trimming code
<n_blownapart>
Found factor 71 ; Found factor 839 ; Found factor 1471 ; The largest factor is 6857 << RubyPanther this is the output. could we take say 839 and see how it was computed line by line ?
<Nilium>
Problem: the pony's tail is always ugly and therefore you have an infinite loop 'cause your pony sucks
<RubyPanther>
Nilium: Only if you don't plan to #primp! and #preen! after #trim!
<havenwood>
why is there a trim that doesn't modify the receiver? i think just pony.tail.trim :
<Nilium>
It's all pointless because the pony's ugly and is better suited for feeding doggies
<RubyPanther>
pony.tail.trim obviously returns a new trimmed tail, and leaves the original tain untrimmed. Pony magic is awesome, k?!
<n_blownapart>
Nilium: throw me a bone.
<Nilium>
The doggies are not ugly
<havenwood>
RubyPanther: oh, good point

noob101: there is also #ruby-lang and #ruby-dev and some others too

noob101, Use functions, it makes it easier for everyone to understand what the code is doing, and to identify bugs
<noob101>
centrx functions are methods right?
<centrx>

I only like PMs that are full of ASCII pr0n and ponies, weapons and code get checked in at the door.
