like config_option = true, config_option.value = 'foo' ?
<apeiros>
like show_foo_part = true/false
<smathy>
riceandbeans, the former.
<apeiros>
alternatively what baweaver showed - set it to nil if it should not be shown, to any non-nil/false value which you can use in the content part too if it should be shown.
<smathy>
riceandbeans, then just `if your_var`

...ok...I think I'll be good then, just worried about edge cases
<Ox0dea>
First day with Ruby, eh?
<apeiros>
and - surprise - only nil.nil? is true. and only nil/false won't branch into `if foo`
<riceandbeans>
not exactly
<smathy>
riceandbeans, I wouldn't use .nil? - just test the var. false.nil? is false, and the last thing you want is for `show_stuff = false` to SHOW the view.
<riceandbeans>
:\ yeah
<riceandbeans>
it doesn't help that it's for a giant config file so spotting an error is a needle in a hay stack

I am creating a poker simulator with Ruby and it contains a module Ranking that checks an array of Cards and determines what combination you might have.
<ruby-lang326>
My question is a module the right approach? I was wondering if I should make that a class instead. Also I am not sure how to start with testing a module.

modules are the easiest to test
<RickHull>
i start with them first
mistermocha has quit [Ping timeout: 246 seconds]
<RickHull>
module methods (at the class layer) have no private state
<RickHull>
so output generally just depends on input
<RickHull>
aka "static" methods
<Ox0dea>
ruby-lang326: Why not a #value method on a Hand class?
<RickHull>
generally you can only go so far with a bare module, and you want to add state. then just call it a class, def initialize, and figure out what you need for private state

hey guys I’m looking for the best resource for learning basic algorithms in either ruby or JS. Preferably something at the beginner level with examples of real world application on stuff like: [Hash tables, Linked lists, Breadth-first search, depth-first search, Quicksort, merge sort, Binary search, 2D arrays, Dynamic arrays, Binary search trees, Dynamic programming, Big-O analysis]
<benzrf>
tref: this is not stuff that has real world application if you'rew riting ruby
<benzrf>
*writing
<benzrf>
tref: most of this stuff is only things that get implemented in C

well, maybe not big-o

You could stick all the strings in an Array and say `strings.each { |s| write_to_file s }` or some such, but that's not much of an improvement.

also what's write_to_file
<mr_oh>
suprising, but @variables work without any defined classes
<shevy>
I believe it writes to a file
<baweaver>
kinda unnecessary honestly.

it's more of output to file, not process_products

mr_oh yeah but actually when you are already using @variables, it's just a tiny extra step to write classes

Also, @instance_variables don't go on classes; they go on instances.

More precisely, `self` is `main` at the top level, and Object is the "default definee".

So I've compiled Ruby 2.3.0. Looks like my gem's extension need recompiling. As rb_data_object_alloc is DEPRECATED_BY(rb_data_object_wrap
<paradisaeidae>
Though when invoking gem, it loads the gems, one is ffi which halts.
<paradisaeidae>
So cannot rebuild.

juria_roberts: Look into the merge function
<roelof>
But still I think answer << number schould be a array not seperate numbers
<norc>
roelof: Calling join on an array coerces all elements to string and then joins them together. Thus [10, 11].join would produce a String "1011". Calling to_i on that converts that string back to a number.
<madgen>
well the answer is an array and you are adding all permutations
<norc>
Just to answer your initial question.
<madgen>
it is an array
<madgen>
puts prints all array values in a newline

roelof: also that's now how you want to use inject it suffices to state the operation in the block eg. sum * number and the assignment back to sum is not necessary.
<madgen>
>> (1..10).inject(1) { |sum, number| sum * number }

and even the argument to inject is optional as when you don't pass that argument, inject just initialises the accumulator to the first element in the list. In this case very conveniently 1, but for just doing a product it doesn't even have to be 1.

I'm trying to make sure my rails app is thread safe, and it's kinda scary
<benlieb>
There is a section called "Class instance variables" that says that "Class instance variables" can be not thread safe
<benlieb>
"In this case, calling the layout method causes Rails to set the class instance variable @_layout for the controller class. If two concurrent requests (served by two threads) hit this code simultaneously, they might end up in a race condition and overwrite each others’ layout."
<benlieb>
So it seems like class instance vars are set outside of a method, and a "instance" var isn't?

benlieb: I think "class instance variables can't be thread-safe" is a mischaracterization. I won't read the full article, but it's all about what they say at the start: it matters whether you share mutable state or not.
<apeiros>
and as it is in ruby, you can share *all* variable types across threads, even local variables.
<apeiros>
benlieb: yeah, "class methods" is again, just a fancy term for "instance methods on the object's singleton_class"
<apeiros>
there's only one kind of methods in ruby, and that's instance methods.

it's just more convenient to say "class method". and it's widely understood what is meant. even though sadly many rubyists miss the technical background.

alsu, force_encoding just changes the encoding flag of the string, so "a utf-8 string".force_encoding("anything you like").force_encoding("utf-8") will always be valid, because you've not changed the string, just changed the encoding flag to something else, and then (back) to UTF-8.

I’m not sure exactly where this ruby dictionary is coming from that it has ASCII-8BIT fields. ultimately, a different JSON encoder from a different language. some part of the ruby JSON parser or the ruby YAML parser decided it must be binary data, not UTF-8

Radar: ok, I'll replace the bare numbers w/ an enum

but why should I contain the entire string when I only need some representation of it
<P4Titan>
the string bears on more meaning that an enum
<P4Titan>
yet is bigger, slower, etc.
<smathy>
Bigger?!?!
<P4Titan>
I simply wish to condense my case statement to something more elegant/clever

P4Titan: I have a tip for condensing it: don't write a case statement when you don't need one.
<Radar>
P4Titan: 0 lines of code, 0 bugs.
<Radar>
Store the string in the DB
<P4Titan>
Tho may u give me a reason as to why?

What do you think we're writing here? The head move routines for a hard drive?

You will make life hard for future-you and future-other-people.

You need to make it EXPLICIT in your codebase that when the share_type is "network" it really means "network"
<smathy>
P4Titan, your reason, "bigger, slower" is absurd - that's our reason for picking the option that is easier to implement and understand.
<Radar>
becuase nobody knows that 1 == "network" unless they've really looked hard into the problem before.

Radar: I fear your sarcasm does not impact *my* project. Moreover, I simply wish to learn some Ruby posing an interesting question which surely can be simplied in some clever manner, tickling ur inner rubyist brains.
<Radar>
ok, glhf bye
<smathy>
P4Titan, comprehensible, explicit values are not a marginal benefit, but no one's going to stop you, but we're the wrong people to ask for opinions on shitty workarounds to bad choices.

P4Titan, and while you're at it, you should definitely switch away from ruby if the slowness of using strings bothers you.

I would say that my general mentaility (for this project at least) is: if it can be better, why not make it better.
<P4Titan>
Anyway, I appreciate your input and will take it into future consideration.

so lost, I am reading a file of words into an array but for some reason I can't find the index of a string that is in the array. '==' doesn't seem to work
<rehat>
I tried just array_var.index("bat") but that returned nothing
<Canar>
watching you ruby pros answer newbie questions has honestly advanced my ruby understanding so much... i haven't ever joined an irc channel that improved my understanding quite so much

Or else you forgot to #chomp your lines.

rehat: Check: array_var.grep /bat/
klka has quit []

<dostoyevsky>
hmmmm... there is no unicode symbol for batman... how are you supposed to call him when you need him?
<dostoyevsky>
with a jpg?
<rehat>
do I need to do anything special with strings read from a file? I printed out the .class and is say String and there are no '\n' or '\r' in the puts. I made another array and hard coded the strings and index("bat") worked

rehat: `puts` will conceal line endings from you; use `p` for debug printing.
