<shevy> you don't say what problem you have
<shevy> {"welcome"=>2, "to"=>2, "the"=>2, "jungle"=>2, "baby"=>1}
<shevy> you can use a regex btw
<shevy> ["welcome", "to", "the", "jungle", "book,", "baby"]
<shevy> if you don't need the ,
<shevy> you can delete it
<shevy> from: current_word = string.downcase.split(" ")
<shevy> to: current_word = string.downcase.delete(',').split(" ")
<shevy> ruby is little operations combined together rubie
az7ar is now known as az7ar_away

<rubie> here is a similar one to mine
<rubie> but it works

<nowthatsamatt> tmoore: haha, nice
<nowthatsamatt> i ended up just doing it all in bash
<shevy> rubie you need to start thinking in operations
<rubie> what do you mean by that
<shevy> you have input, you want to achieve a desired output
<shevy> so you must apply an operation in between those two right?
<rubie> right
<shevy> k, so the input is given to you, but you can modify it
az7ar is now known as az7ar_away
<shevy> so the next thing is - you need to ensure that you have a proper output
<shevy> <rubie> but what if i dont know what puctuation marks i will get
<shevy> you have if/else clauses
<shevy> if string.include? ','
<shevy> elsif string.include? '.'
j_mcnally has joined #ruby
<shevy> everything can be built around operations

<shevy> for debugging use p object
<shevy> or require 'pp'; pp object
<shevy> the 2nd example is simpler to understand because he breaks the chunk down into an intermediary value
<shevy> you really should also use temp variables, they make everything much simpler
<rubie> what are temp variables
<maplatoj35> anyone can point me in the right direction...smth im missing. my methods always return false https://gist.github.com/anonymous/9fa444ec0196a0a4429d

<rubie> shevy: i fixed it by creating a nested loop. to me it seems that by asking if the dictionary word is included in the substring word, if its not an exact match it will still say that its included. so it gets around the punctuation, but if you had a word like jungleeee it would still count it, because jungle is included in the element jungleee

<maplatoj35> how to test for those
jdj_dk has joined #ruby
<sevenseacat> you dont test private methods
<sevenseacat> they are private
<shevy> rpag well he eats lasagne bolognese I guess; I eat vegetable lasagne :(
moritzs has quit [Remote host closed the connection]
<rpag> i've tested them before, i usually do something like: subject { method(:name) } it { expect(subject.call).to eq(1) }
mercwithamouth has joined #ruby
<sevenseacat> that defeats the purpose of them being private
<rpag> why?
<sevenseacat> if they're private, the outside world does not know about their presence
<sevenseacat> they can be moved, changed, rearranged, deleted, have their interface change, and the outside world does not give a shit
<sevenseacat> but now your tests do
<sevenseacat> which is wrong
<shevy> perhaps he wants to do secret private testing
mengu has quit [Ping timeout: 265 seconds]
<maplatoj35> sevenseacat: then it defeats the purpose of testing..we don't test for the outside world
<havenwood> but are you testing your tests?
<banisterfiend> sevenseacat do u mock private methods though?
<sevenseacat> banisterfiend: no.
<banisterfiend> stub?
<SpikeMaster> testing the internals should be OK. Like testing the car engines defribulator is OK even if that is not exposed throught the drivers interface.
<sevenseacat> private methods do not exist outside the class.
<banisterfiend> i meant stub, sorry
<sevenseacat> no.
<banisterfiend> you dont mock methods, you mock objects :)
Synthead has quit [Ping timeout: 256 seconds]
<havenwood> i mock mocking

<unshadow> lets say i have a loop that spawns a new thread for each event, in the new thread I have a different loop which checks for specific parameters, if the parameters are blabla i'll do something , else i'll do something else, lets say that in the "if" after i did my magic I want to close the current thread so it wont execute unneeded code, is there a thread.stop or thred.exit ?
<canton7> just end whatever operation you're doing in the thread

<zenspider> unshadow: thread's loop should break, thread will stop running at the end of its block

<zenspider> Nevermind. I've lost interest. If I wanted to pull teeth I would have become a dentist.
<txdv> you can become a hooligan
<zenspider> do hooligans pull teeth?!?
<zenspider> I guess it's prolly cheaper to start as a hooligan
<deepy> If I were a hooligan, I would pull your teeth and sell them to a dentist
<zenspider> but I still don't want to pull teeth, so that's out. Not into sports either.

<Psy-Q> when testing a gem, what would i require in my rspec files? can i require 'cider_client' in this case? https://github.com/psy-q/cider_client

<Psy-Q> it's my first gem, sorry if that's basic

<rpag> as long as 'lib/' is on $LOAD_PATH that should work
gauke has quit [Quit: gauke]
<Psy-Q> rpag: that's why i was wondering: when i execute rspec (even with bundle), it should add the lib/ from this very gem to the load path, right?
<Psy-Q> the spec seems to work at least, but i'm not sure if that's some magic happening
<rpag> you dont seem to require the library or try to, but anyway, if you plan to use bundler you could require 'bundler/setup' followed by Bundler.require :default to require all the dependencies in your Gemfile

<chrisbolton> I have a nested hash and I’m trying to remove a key/value pair at multiple levels without a lot of looping. Here is a sample hash (https://gist.github.com/cbolton-sge/69b5258b4398affc3d3f) and I’m trying to remove application_id and value at every level. Any ideas? I can do it looping just looking for something a little more elegant.

<zai> pontiki: nothing meaningful. there's a way to encrypt a PNG (with AES128) and turn it into another valid PNG. It involves some tricks, but it's possible. I want an SVG that encrypts to a PNG. But I don't want to add an extra script for the encryption. I want to have the script inside the SVG as well.
<pontiki> that's the old orange, and one of my favourite weirds
