but what if the clone turns evil?
banister has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<yorickpeterse>
maybe they'll start replacing your Ruby with Python

<workmad3>
yorickpeterse: if a clone with my exact mental state would do that, then the same possibility exists for myself
<yorickpeterse>
well, that depends on if something goes wrong during the cloning process
<workmad3>
yorickpeterse: at which point it wouldn't be my exact mental state
<yorickpeterse>
clearly we need immutable clones
<workmad3>
the really great question is - if you create a being that is an exact quantum copy of yourself (ignoring the impossibility of this under the 'no quantum xerox' issue), which one is the original?

<workmad3>
yorickpeterse: if you examined them, they would both have the same history
<yorickpeterse>
Well yeah
<workmad3>
yorickpeterse: because they're exact duplicates of the same quantum states
<yorickpeterse>
well, it depends on what one means with "original"
<yorickpeterse>
e.g. original as in "who came first"
<yorickpeterse>
vs "will the real slim shady please stand up"
<workmad3>
jhass: I'd personally say 'both' ;)
<apeiros_>
workmad3: another advantage is that we have an understanding of what the other(s) are capable of
<apeiros_>
I wonder how quickly the clones would start to deviate
<workmad3>
apeiros_: that's based on the assumption that you have a perfect (or at least good) predictive model of your own actions internalised in your brain
<jhass>
does the clone know its the clone or do both think they're the original?
<yorickpeterse>
apeiros_: not if it's an immutable clone
<yorickpeterse>
put some functional programming up it's brain
<yorickpeterse>
* its
<yorickpeterse>
damn it
<apeiros_>
jhass: with a perfect clone, would it matter?
<jhass>
for the derivation it would
<apeiros_>
I guess I'd accept the fact that there are now two/many originals
<yorickpeterse>
This reminds me of that Arnold Schwarzenegger movie
<yorickpeterse>
"IF I'M NOT ME THEN WHO THE HELL AM I?"
<apeiros_>
and re: many - I doubt I'd stop at one clone :D
MXfive has joined #ruby-lang
* apeiros_
wonders whether he and his clone army would have to pay taxes only for a single person…
<yorickpeterse>
Ah yes, the original total recall
<workmad3>
jhass: for an exact quantum state duplication, both of you would have, at the instant of duplication, exactly the same mental states, so would have exactly the same knowledge up to the point of duplication
<workmad3>
jhass: in a strict interpretation, with an exact duplication of all the quantum states in your body, not only would you both think you're the original, you both *would* be the original
<jhass>
one problem there is that both versions would at least in the short term try to do exactly the same next, fighting about uniquely available resources
<jhass>
so that's already a big potential for huge derivations
<workmad3>
jhass: sure, but they're all future derivations, not past ones
<jhass>
sure
<workmad3>
jhass: hence why I'm saying 'up to the point of duplication' ;)
sgambino has joined #ruby-lang
<workmad3>
of course, this is pretty moot as the 'no quantum xerox' principle is essentially a demonstration that you can't non-destructively copy exact quantum states

Hi, question to all. How does parsing of negative numbers work. If I have `foo.method -1` in irb this returns wrong number of arguments (1 for 0). However, in some time (within Rails) this resolves to Fixnum minus Fixnum. Not sure why its inconsistent (method always returns Fixnum). Any thoughts as to how I could work out why?

lee-jon: what do you want to do? `(foo.method) - 1` or `foo.method(-1)`?

oh, 1 for 0. so the former

foo.method takes no arguments

The first. I can easily solve it by fixing the whitespace. I’m just wondering why it sometimes works (I can’t replicate that in IRB)

I'm trying to read all the headers off all the CSVs in a folder, and currently I'm trying to collect them all into hash and am merging them as I go. Unfortunately while it seems to overwrite duplicates its behaving weird when I want to add keys

note the manpage, the names are really counter intuitive
<maloik>
only thing I'm not sure about is the question a colleague asked: "I want to test if a certain suite can be forced"

or can it somehow redirect to use another one

Basically the idea is to read the headers off the CSVs in the directory to create a master list of headers, and then map each row out according to the master header list

Soviet_jesus: Use the `[]` and `{}` literals instead of `Array.new()` and `Hash.new()`.

Hey guys I've been reading a style guide and I see that 'for' is very evil in ruby
<tsujp>
I am, however, trying to loop a string to index - x, where x is a variable passed in. Currently i have:
joaomdmoura has joined #ruby-lang
<tsujp>
input_string.each_char.width_index do | element, index |
<tsujp>
if ( index < input_string.length - 5 )
<tsujp>
That's two levels of indentation, surely there's a better way!
<apeiros_>
input_string[0..-5].each_char …
<apeiros_>
no need to test every iteration
<tsujp>
Let's say -5 was a varaible though, does that work?
<|jemc|>
yep
<tsujp>
I see that it does
<tsujp>
EXCELLENT
<tsujp>
THanks guys, I was thinking that was wrong (new to ruby) so I wanted to double check

One other thing while I am here, I have seen scoped methods and what not (coming from rails here) where you can type say 'somestring'.quick_sort and it uses 'something' as its operand
<tsujp>
How do you define a method like that, since this may not apply to just strings. It could be arrays, or integers etc.. or is it safer and cleaner to just make it like quick_stort( to_sort, blah )
<tsujp>
As a crude example
<tsujp>
I tried Googling scopes and what not but got the typical scope you'd expect like inside and if statement etc..
<tsujp>
Control flow stuff, which isn't what I am after
<|jemc|>
they aren't scoped differently, they are monkey-patched
<|jemc|>
so someone defined String#quick_sort
<|jemc|>
and unless you are using 'refinements', that method pollutes everyone's Strings for the whole application
<tsujp>
There's no way to monkey-patch that to various types without copy-pasting?
<|jemc|>
ah, well you can do that with a module
<tsujp>
I take it that's not a very Ruby thing to do for such a trivial problem like a sort then
<tsujp>
Ohh, can I get a rough example?
<workmad3>
tsujp: considering arrays have built-in sorting, yeah you wouldn't do that for something like a sort

joaomdmoura has quit [Remote host closed the connection]

workmad3 nice, I can chuck arrays out now

So for instance 'my string'.foo would return 'my string' and execute the method foo so I can output say... puts "#{ input } foo"

So 'hello mr.'.foo becomes 'hello mr. foo'
<tsujp>
Yeah I want to know how and if it is possible to access that string, or whatever, the method is attached to.
<workmad3>
tsujp: well, you could write your method like 'def foo; puts "#{self} foo"; self; end'
<tsujp>
ahk sec
<workmad3>
tsujp: 'self' is the object that the method was called on (sometimes called the receiver or the target or the self-context)

<tsujp>
Last question then, why must it be wrapepd in the module?
<workmad3>
tsujp: it doesn't have to be wrapped in a module... it has to be defined on the String class somehow
smoitra has joined #ruby-lang
<tsujp>
and the module wraps to all of those I presume
ecnalyr has joined #ruby-lang
<workmad3>
tsujp: it's just that modules give a convenient way to parcel up a bunch of methods and easily attach them to a class (that's what 'include Foo' does)

yeah looks like it since its working with integers and stuff too now

tsujp: you could also have done 'class String; def foo; blah; end; end'
<tsujp>
Yeah ruby is very implicit (which I love) but a simple `include Foo` seems to skip the whole "ohh thats being included for x y and z classes now" gets past me
<workmad3>
tsujp: did you type 'include Foo' at the top level in IRB by any chance?
<tsujp>
Yeah
<tsujp>
Well this is in two files im just executing with Ruby
<workmad3>
tsujp: right... then what you just did was the equivalent of 'class Object; include Foo; end'
<tsujp>
1. sort.rb, has JUST that module code
<workmad3>
tsujp: so you monkey-patched *everything* in ruby... which is not a good thing to do
<tsujp>
2. exec.rb has JUST `include Foo; 'test'.foo` and it's all good
<tsujp>
Ohhhh
<tsujp>
So in future I should definitely restrict this to types only
<tsujp>
or be normal and use a method that accepts two arguments
<tsujp>
?*
<workmad3>
tsujp: that's not normal in ruby ;)
<tsujp>
arggghhhh
<tsujp>
One last question turned into many
<tsujp>
Then what in your opinion is the most ruby way to do this kind of problem?
<tsujp>
Which is bascially calling custom sort methods on strings and what not
<workmad3>
tsujp: but yes... you should avoid monkey-patching or modifying core classes and objects as much as possible
<workmad3>
tsujp: why would I be wanting to call custom sort methods on strings?
<tsujp>
It's a type of regex matching for a single use case I need
<workmad3>
tsujp: "fooo".chars.sort {|a,b| custom comparison of a and b here}
<tsujp>
'foo'.naive_sort( 'oo' ) would return 1 since 'oo' starts from the second position
<tsujp>
Nah this isn't traditional sort it's custom algorithms
<tsujp>
workmad3 has to be something I write though ;)
<workmad3>
tsujp: meh, sounds like a crappy homework assignment that's forcing you to jump through arbitrary hoops to do something that ruby already does for you
<tsujp>
Essentially, that's why I was very confused
linc01n has joined #ruby-lang
<tsujp>
I was trying to think of a novel way to do it but I think I'll just stick to this:
<tsujp>
naive_sort( 'foo', 'oo' )
<workmad3>
tsujp: and if the teacher won't accept "foo" =~ /oo/ then they're teaching nothing of any use
<workmad3>
tsujp: hell, that isn't even sorting
<tsujp>
Well it builds up into sorting, the index is the most important part
<tsujp>
I'd agree it's very crappy
<workmad3>
tsujp: you can get the index using "foo" =~ /oo/... so use that as part of the rest of your sort
<workmad3>
tsujp: what sorting algorithm are you implementing then?
<tsujp>
I might just do that then
<tsujp>
all of the common ones
<tsujp>
quick sort, insertion sort etc.
<workmad3>
tsujp: ah, lovely... planning on a long, interesting career in algorithm research? ;)
<tsujp>
f*ck no
<tsujp>
Just a unit I have to do at uni, final year.
<tsujp>
Haven't used Ruby yet, was hoping to get into it but stuff always crops up
<tsujp>
Love it so far, just trying to get as much knowledge on it as possible
<tsujp>
and figure out 'the ruby way' of going about things
<workmad3>
tsujp: it's a shame you can't just hand in 'something.sort{|a,b| b <=> a }'
<tsujp>
workmad3 I agree hahaha
kaip has joined #ruby-lang

Greetings all. I think I have a somewhat simple question. using ruby regex, how does one match sequential numbers within a range? Example: Every number from 190-209 (190,191,192,etc)
<bougyman>
that's not really a job for regex
<bougyman>
you can construct it
<bougyman>
a common one is 1-255 (for ip octet ranges)
<apeiros_>
0-255 ;-)
thebastl has quit [Quit: Leaving...]
<elricsfate>
I'm trying to do this for puppet nodes. You can use regex in the name.
<apeiros_>
elricsfate: as bougyman said, regex are badly suited for that. what you'd do is you'd enumerate all variations
<elricsfate>
apeiros_: [0-255] would work as expected?
<apeiros_>
you can compact that a bit
<bougyman>
/(?:2[0-5][0-5]|1(\d\d)?|\d\d?)/ type stuff
<bougyman>
elricsfate: no, it wouldn't
<apeiros_>
elricsfate: it would work as I expect it, but not as you do
<elricsfate>
apeiros_: Gotcha
<apeiros_>
[0-255] is [50-2] is [0125]
dorei has joined #ruby-lang
<apeiros_>
i.e. "match a single char which is either 0, 1, 2 or 5"
<elricsfate>
I guess I'll just have to do a node def for each system then
<apeiros_>
elricsfate: or match a 3 digit number and test after the match
<bougyman>
or turn it into an int and do a proper range match
<apeiros_>
or don't use regex at all
<elricsfate>
apeiros_: ?
<apeiros_>
range.include?(number.to_i)
<bougyman>
apeiros_: yes, I wouldn't use regex for this.
<elricsfate>
apeiros_: Well that's the problem, it's either regex or bust
<apeiros_>
elricsfate: how come?
<bougyman>
is this a homework assignment?
<bougyman>
ah puppet node search.
<elricsfate>
bougyman: apeiros_ No it's not. I'm attempting to use a Puppet Node def which requires an actual string or a regex
<bougyman>
yeah I hear ya. chef allows globs, not real regex, for node search.
<elricsfate>
I think I have an idea. I can do two node defs with two different regexe. One for 4319[1-9] and another for 4320[1-9]
<bougyman>
so you'd construct /19\d|20\d/ for taht.
<anekant>
" <apeiros_> doing something bad or good is quite unrelated to authority" --> if using relative the old way is wrong, I don't wanna be right
<bougyman>
elricsfate: that's what mine does.
<bougyman>
the | in the regex is alternation, it tries both.
<apeiros_>
anekant: that makes you ignorant, perhaps even stupid. it does not make you a rebel.
<havenwood>
anekant: Add ".bin" to your PATH for good measure.
<apeiros_>
havenwood: also .
<havenwood>
anekant: Or just "."
<havenwood>
apeiros_: indeed! >.>
<elricsfate>
bougyman: Ah thank you. That seems to do the trick. 43(19|20)[0-9]
<jhass>
I think .. would be more interesting though
<elricsfate>
You start with a problem and think regex is thr solution, now you have 2 problems.
<bougyman>
hey, I have no hate for regex.
<bougyman>
it solves a great many problems.
<bougyman>
and causes a great many more, which some people compensate me to fix.
<bougyman>
it's win-win.

<apeiros_>
anekant: because you don't actually call initialize
<anekant>
has this changed?
<apeiros_>
no

folks, what's the proper way to propagate an object freeze in ruby? override it and manually call freeze in ivars?
skade has joined #ruby-lang
<hakunin>
i'm writing a gem, and i want objects of my classes to be properly freezable
<hakunin>
(on demand by user)

well, the default behavior is to be shallow in that, so one could argue that doing it deep is the unexpected thing
<hakunin>
e.g: class Policy; def initialize; @checks = [] end; def add(check); @checks << check end end # so i want users to be able to freeze a policy such that add raises error

<jhass>
you could add manual checks, raise if frozen?
<apeiros_>
hakunin: yes, like with dup/clone too.
<apeiros_>
hakunin: just be aware that you potentially mutate arguments this way. and that's usually considered not nice.
<hakunin>
apeiros_: re: arguments - not exactly, my example isn't precise, but i get what you mean
<apeiros_>
hakunin: well, to put it differently: the nested objects might be referenced elsewhere. and they get mutated from "far away"
sepp2k has quit [Quit: Konversation terminated!]
<hakunin>
apeiros_: just that in my case those checks are blocks-turned-procs, so likelihood decreases, unless they decided to pass around a proc
<apeiros_>
why'd you freeze a proc?
<apeiros_>
I don't think you can mutate those anyway, no?
<hakunin>
apeiros_: i'm mostly concerned about the @checks array
<hakunin>
apeiros_: i probably won't even be touching checks actually now that you bring it up :)
