<masterasia> I have a year
<masterasia> (Time.new.year)
<masterasia> how can I iterate and count down?
jusa has joined #ruby
<masterasia> I can subtract -1 to get the next year but I was wondering if there was an enumerable method to do it for me
<masterasia> instead of writing a loop myself
<adam12> masterasia: Maybe #upto or #downto ?

<mnemon> never seen anything focused on those but if you understand the concepts, reading up on ruby networking/http libs should be enough.
<mnemon> *enough to get you started.
<canton7> yottanami, ruby has multiplication and division. What else do you need?
<zun> mnemon: thx
<yottanami> canton7, lazy way :D
<canton7> yottanami, I've still no idea what you're asking for, I'm afraid
<canton7> there are loads of ways to calculate percentages, depending on what you're after

<Bish> how does one detect if a string isn't correct utf8?
* Bish sends data to postgres, postgres transactions dies becaus @user has not sent valid utf8
* Bish catches the transaction, but postgres does not want me to continue it

<Mon_Ouie> Hard to say from just that. I'm not sure what the method does, whether or not it even makes sense for v to not be a string here, and whether the rest of the code can handle strings that aren't in UTF-8.

<Bish> Burgestrand: how do people handle this problem?
bkxd has joined #ruby
<Burgestrand> Bish it depends a bit on context, typically you try to have the source text encoding known at all times, passing it along together with the text
<Burgestrand> Bish not always so easy, especially if you're dealing with software where the text encoding isn't known, once you're in that situation all bets are off and the text you're managing might end up making no sense at all
<Burgestrand> Bish just like in human language, if I give you the word "gift" but not which language I'm referring to, to me it might mean "poison" (swedish) but to you it might mean a present (english)
aupadhye has joined #ruby
<Burgestrand> (then again, in swedish the word "gift" could be either "poison" or "married", so even within the same language it's not so simple :))

<apeiros> _DanN__: uuuuh, you are aware that $vars are *globals*?
<apeiros> (from your code, I actually know you aren't…)
<jhass> _DanN__: first of all I strongly suggest you abandon single letter variable names for pretty much anything
<_DanN__> no I am not :( this is my second day with ruby hell :(
<apeiros> ruby hell?
<havenwood> _DanN__: meta hint, but name your gist filename with a .rb extension for syntax highlighting
<jhass> heh, its fine
<apeiros> that's an interesting attitude. I'm quite certain it's not very helpful.
<jhass> well or erb in this case ;)
<_DanN__> jhass: this is just a snippet .. this @s variable is pulled from puppet
d^sh has joined #ruby
<jhass> so, you want to do something for the last device in the list?
<_DanN__> jhass: correct
sspreitz has quit [Ping timeout: 240 seconds]
<jhass> try iface = @s.last instead of the loop
<havenwood> _DanN__: don't create any $global_variables or @@class_variables, just avoid introducing either of those entirely
<_DanN__> jhass: this would include 'lo' which I can not avoid in this case
<jhass> or current_device = interfaces.last or whatever
<jhass> so the second to last?
hahuang61 has quit [Ping timeout: 260 seconds]
<jhass> current_device = "interface_#{interfaces[-2]}"
<havenwood> _DanN__: simplify `if !@s.nil? ` to just `if @s` (if you really need this check at all)
<_DanN__> jhass: I'm not really positive that 'lo' will be the last item in the array
<havenwood> _DanN__: consider `@ifaces.each do |iface|` or `@interfaces.each do |interface|` for naming
<_DanN__> I'm getting corect value in cur_device
<jhass> well, .sort it then ;)
<_DanN__> problem is with printing its value
<_DanN__> so this: set trapSourceAddress <%= $cur_device %> is the problem

<_DanN__> I removed globals and got rid of single char variable names
<_DanN__> 1st 3 lines is the real example what I'm getting in variable 'interfaces'
<_DanN__> this will produce: set trapSourceAddress interface_eth3 readCommunity mtflabForpmfm writeCommunity mtflabForpmfm trapCommunity mtflabForpmfm
<_DanN__> but I'd rather have: set trapSourceAddress 1.1.1.1 readCommunity mtflabForpmfm writeCommunity mtflabForpmfm trapCommunity mtflabForpmfm

<apeiros> interfaces = {"eth3" => "1.1.1.1"}

<_DanN__> apeiros: yes, that would be ideal solution .. like I said: this is puppet magic :-|
<apeiros> -1-1 is an interesting way to say -2
<apeiros> puppet ain't magic
<_DanN__> apeiros: haha correct :)))
<apeiros> any sufficiently analyzed magic is indistinguishable from science
<jhass> ^, also does this ever need to support persistent interface naming or have eth10 or above?

jgt has quit [Ping timeout: 240 seconds]
<jhass> assuming no persistent interface naming and eth9 max
<jhass> with peristent interface naming you need another strategy for picking the right one anyway I guess
<_DanN__> so there is no way to get a value of variable which is defined as a value of another variable ?
<jhass> none you should go if there's any other way
<jhass> and in 99% of the cases there is

levifig has quit [Ping timeout: 260 seconds]
<jhass> none of these would define @interfaces for you ;)
<jhass> (or interface_eth3 for that matter)
<_DanN__> correct :) that's why I put it in the code ..
<jhass> well you said in your actual code you don't
<_DanN__> thought that this: interface_eth3="1.1.1.1" defines it
<jhass> it does but you rejected apeiros suggestion of how you should define it instead
<jhass> I thought the reason was that you don't actually do it in your actual code
<jhass> if that's not true then you should go with apeiros solution
<_DanN__> to define an array for every interface ?
<jhass> a hash that has all the intterface => ip mappings you need
<jhass> instead of creating a new variable for each mapping

<TheSuper> Thanks for reminding me of that (I almost never use groups)
<TheSuper> Going back to an actually relevant topic...
<TheSuper> I think it's a mistake to allow #[]= to be defined with one argument
<TheSuper> you can also apparently define :*, :+, and other operators with two arguments, which seems to make them impossible to call without using #send
esObe_ has quit [Ping timeout: 240 seconds]
fmcgeough has quit [Quit: fmcgeough]
<jhass> it's a dilema, either you just special case the invocation side, which is nice because general but then weird on it, or you special case the definition side too having even more special cases
esObe_ has joined #ruby
<jhass> I'm not decided yet which variant I prefer
<TheSuper> I don't think there's ever really a reason to have * or + be anything but a binary operation
<matthewd> Constraining the definitions would be very weird to me, because that misses the fact that as far as the object is concerned, they're Just Methods
<TheSuper> it might make implementing the language a bit harder, but Ruby is supposed to optimize programmer happiness, right?
<allisio> TheSuper: You don't need #send to say `1.+(2, 3)`.
<TheSuper> it is a special-case of method definition though, you're right.
<TheSuper> Oh yeah, an explicit . works as well
dviola has quit [Quit: WeeChat 1.7]
<matthewd> The language provides convenient syntax shortcuts to make certain method calls (i.e., the operators), but that's all they are
<TheSuper> ruby does already special-case the invocation of those methods by not requiring a "." though, so I think it's reasonable to restrict the definition.
<jhass> so that gives you one quite well defined special case, x.special(y) can also be written as x special y
<matthewd> Otherwise they'd no longer be methods -- they'd be defined operators, which happen to use a method-like definition syntax
<TheSuper> Then again, this is also a case where it's sort of a "don't do that really stupid thing"
<jhass> the point is one special case is generally better than two
<allisio> Just for shits and giggles, is this the "right" way to do it? https://eval.in/769796

<allisio> Oh, right...
<TheSuper> It would be kind of neat if Ruby defined certain unicode character classes as operators, actually
<TheSuper> like swift does
brodul has joined #ruby
<TheSuper> so you could use `def ≠(other); ! (self == other); end;`
<TheSuper> and invoke it like `bar ≠ foo`

[Butch] has quit [Quit: I'm out . . .]
<TheSuper> Oh no unicode operators are awful in 99% of the cae. If >>= was just named `flatMap` I bet Haskell would have 50% more adoption than it does
<jhass> they're just harder to remember and more often ambigous compared to methods with a nice name
<TheSuper> honestly
jeffreylevesque has quit [Ping timeout: 260 seconds]
<allisio> TheSuper: But not really, though.
<allisio> It's all just symbols, y'all.
<allisio> We just have ones we're more accustomed to using.
<TheSuper> 50% is an exaggeration but haskell's tendency to use one-character variables and custom operators hurts adoption
<TheSuper> It is just symbols, but I can read `flatMap` and sort-of-kind-of get what it means
jenrzzz has joined #ruby
<allisio> Why couldn't that be true for `>>=`?
<TheSuper> while >>= is like "Right shift equals..?"
<TheSuper> Well, it can be
<TheSuper> after I know it means "flatMap"
<jhass> the difference is that we're far further with having agreed what ASCII symbols stand for than the unicode ones ;)
<TheSuper> but if I'm just coming across it, how should I know?

<superscott> 200.chr gives you "\xC8", (personally) don't know what the \x00 would be
<superscott> provided 200 is an int, not a string
<ytti> i think he wants to guarantee there are two bytes
<ytti> i.e. 16bit

<ytti> so pack("S")
<ytti> >> [200].pack("S")

<superscott> touche.
<Tesl1_> ytti: yes, that is
<Tesl1_> thanks
<ytti> ruby kinda sucks for this

<ytti> as there are natively no fixed length numbres
<ytti> so dealing with wire-formats/rawdata is kinad PITA
<Tesl1_> as I can see it is
<superscott> ^ api link to ytti's example : http://ruby-doc.org/core-2.2.3/Array.html#method-i-pack

<ytti> wrote this today to drop bytes from binary formats (well two different binary formats) - https://gist.github.com/ytti/df3eaaec54fc423ae1685d336d08b452
<ytti> would be so much cleaner with actual fixed bit size integers
<ytti> i kinda expected it to be small quick hack, but it ballooned

<zenspider> ytti: you want to remove everything from a stream that matches the keys in BLOCK_TYPE and it wound up being 459 lines long??

<ytti> zenspider, no i'm popping N bytes of each packet inside the file
<ytti> zenspider, file is collection of captured packets
<ytti> zenspider, with bunch of metadata
<ytti> zenspider, and there are headers in the packets which i don't want there

<zenspider> ugh. I can't come up with a better way to do this... I think I need to write a structural/OO matching engine... regexps for objects. anyone know of any prior art?

<adam12> have you been somewhere lately?
<zenspider> was in mexico last week for a conference... mostly just nose down for my client
<adam12> Nice :)

<adam12> Was it on Minitest? :P
<adam12> Speaking of which, *_test.rb or test_*.rb
<zenspider> no, it was on study groups and leveling up your ppl
nitric has quit [Ping timeout: 264 seconds]
<adam12> I definitely need to level up my ppl
<zenspider> plain ruby projects are usually test_*.rb, rails is *_test.rb
<adam12> I need ppl first.
