anyone know a good pattern/gem for exception chaining?
<raz>
one issue that i bump into a lot is that i want to pass/wrap inner exceptions outwards and then generate a readable stack-trace from them
<raz>
this usually results in terrible subclasses of StandardError with domain specific extra fields and such

whats the point of baking cookie dough if it tastes better as dough

<sreich>
I know!
<sreich>
there's about a 50% efficiency loss when I bake cookies
<sreich>
because I eat half of everything I scoop out
<otters>
well as long as you don't bake them to the consistency of granite
<otters>
then I'll take an actual chocolate chip cookie with milk over cookie dough
<sreich>
yeah, I tend to have them more on the soft side
<sreich>
well, the cookie dough is *quite* tempting
<sreich>
especially when you're scooping it
<otters>
I never much liked the dough
<sreich>
you just have to have some..
<otters>
then again, I'm no good at eating squishy things
<sreich>
heh

it's an aquired skill

<vandemar>
suppose class Foo has @v1 and class Bar<Foo has @v2, and one of Foo's functions func1 needs to know @v2. Is the usual way of doing that to def func1(v2) in Foo which does the heavy lifting, func1(v2 = @v2) in Bar that merely calls super? Or is this situation of needing subclass variables in a parent class method a sign that I'm trying to do something stupid?

how are false and nil related if both of them are evaluate falsely, but false != nil
moondiamond [moondiamond!~davec@li389-186.members.linode.com] has joined #ruby
<t-mart>
i mean, "if false" and "if nil" are the same thing when i say "evaluate falsely"
<t-mart>
neither of them are the superclass of the other
<jsaak>
they are different
<jsaak>
if is implemented like this
<jsaak>
when expression == nil or wxpression == false then do something else do something else
<gener1c>
why do it like that?

why not

if it matters

ah you are asking something deeper than that
<gener1c>
its for historical resons
<gener1c>
0 is also null in C :)
<gener1c>
and false
<gener1c>
there you go problem solved
<t-mart>
is it?
<gener1c>
yeah
<gener1c>
0 is false and null
<t-mart>
NULL == 9
<t-mart>
0
<gener1c>
the ascii code for null in c is 0
<gener1c>
not 9
<t-mart>
that was a typo
<gener1c>
ah ok
<gener1c>
and c doesnt have true or false
<gener1c>
0 is evaluated as false
<gener1c>
and the rest of the numbers as true
<gener1c>
plus its alot more comfortable since the result of alot of actions that fail is null
<t-mart>
NULL is a macro i believe. do you know where its defined? or is it inherent to the C?
<gener1c>
lets say i want to grab an element in html using nokogiri
<gener1c>
if i fail i get a null class
<gener1c>
so id write
<gener1c>
while result do; something; result = result next; end
<gener1c>
its more readable
<gener1c>
NULL is a macro in c

||= is bloody amazing
<gener1c>
why didnt i think of it before
<shevy>
what's it do
<gener1c>
var ||= value
<gener1c>
means
<otters>
or equals
<gener1c>
var = var || value
<otters>
or assign, actually
<shevy>
hmm
<gener1c>
it assignes only if the var is not set
<shevy>
so if var exists, it assigns to itself? otherwise it picks value?
<gener1c>
yes!
<shevy>
hmm
<gener1c>
well sortof
<otters>
if it's nil, it assigns
<gener1c>
if it exists it is not changed if it doesnt it gets value
<otters>
usually with ivars
<gener1c>
whats ivars?
<otters>
so if the variable evaluates to false it will get assigned
<otters>
instance vars
<otters>
@var
<gener1c>
ah ok
<gener1c>
this is so smart i love it

flimmern depends on what the game requires
<flimmern>
jensn: if possible for all of them ;)
<shevy>
if it is just text-output game you can use gems
<flimmern>
i usually write them on osx, and the people playing them use windows
<jensn>
On OS X, it is pretty easy.
<jensn>
No idea about Windows.
<shevy>
:)
<flimmern>
what i want is a pre-bundled package, with ruby, all the gems i require, and of course my game
<flimmern>
people hate it when they have to install stuff just to play a game ;)
<jensn>
On OS X you can just write a thin script loading ruby and all the applications, and put all of the gems etc. in the app bundle.

Hello! Where I can find official Ruby docs? I read some guides but there are too small I think :)
<shevy>
Ravik depends.
<shevy>
it is good to read through this here once:
<yoshie902a>
I read the sort {|a,b| a.name <=> b.name} docs but don't understand it. I also saw that link, but still confused.
<yoshie902a>
I'm assuming it's asc order, but I can't find anything to tell me how to do desc order
<dr_bob>
yoshie902a: with sort you reverse the order by simply reversing sides of <=> in the block. With #sort_by it's more difficult: if it's numbers you can prefix a - (minus).

Hello. When I am directly working with redcarpet https://github.com/tanoku/redcarpet I can use extensions by passing objects hash when instantiating like this: Redcarpet::Markdown.new( Redcarpet::Render::HTML, :autolink => true ) . How would I do the same when using Tilt (https://github.com/rtomayko/tilt)? It seems to be doing instantiating by itself. Thanks!

davidcelis, is the ' making the difference here? instead of my double quote?

oh, actually \\\" works

zulax: The fact that you are trying to match double quotes means it would be easier to work in a single-quoted string

Especially if you need no interpolation

You'll have to do less escaping that way

Zal: right now, it outputs the same array as I input

<poppiez>
even though the condition is true sometimes
<apeiros_>
poppiez: .each always returns the receiver
<poppiez>
might be because the block is inside an each
<apeiros_>
it doesn't matter what's in your block
<apeiros_>
[1,2,3].each do true end # => [1,2,3]
<Zal>
poppiez, maybe you want a block like { |s| defaults["js"]["i18n"].include(s) }
<apeiros_>
you want either .any? or .all? instead of .each, I'd guess
<apeiros_>
any? from the code I read
<apeiros_>
Zal: you mean `include?`, include? tests against ==, not eql? (should be the same for strings, though, and then include? would be faster than any? with block)
<apeiros_>
i18n = i18n - defaults["js"]["i18n"]
<apeiros_>
i18n -= defaults["js"]["i18n"]
<poppiez>
apeiros_: wow, didn't know you could do that
<apeiros_>
Array has a couple of Set operations
<Zal>
apeiros_, yes, that's what I mean, I keep forgetting to read the Enumerable methods, thanks. What's the difference between eql? and == ?
akiress [akiress!~akiress@ip70-180-38-30.br.br.cox.net] has joined #ruby

Zal: == is in terms of <=> (bigger/smaller)

while eql? is in terms of key equality
<poppiez>
apeiros_: -= works like a freakin charm
<apeiros_>
1 == 1.0, but !1.eql?(1.0)
<Zal>
apeiros_, got it, thank you
<apeiros_>
Zal: in fact, if you implement <=> and include Comparable, you get == defined in terms of <=> for free (== will then be true if <=> returns 0)
<Zal>
excellent
<Zal>
what's the method name for <=> ?
<apeiros_>
heh
<apeiros_>
either 'comparison operator' or 'spaceship operator'
<apeiros_>
there might be other names too

I mean, how is it written when I'm implementing it.
