hi if you have if, elsif, elsif, else logic, technically which expressions get an end keyword. if if and else are one statement, it seems to me that elsif blah and elsif blahblah would be two separate statements.

one thing is, to learn oop, I need to do it *constantly* or I forget everything.

<pipework>
"I'm one of the person that uses &&/|| for value and and/or for side effects, which means I never use and/or" sounds like you use and/or for side effects and that you never end up actually using them.

jhass: is that like if you're doing a shallow clone vs. a deep clone, stuff is changed or unchanged inadvertently?
<pipework>
So calling a method that might not modify state and applying the result to a local is a side effect?
nkumari has quit [Remote host closed the connection]
<jhass>
potentially. I should clarify that I meant I use them to signal what I care about, the value or the side effect
<jhass>
if I care about the side effect, I use the expression for control flow
dcunit3d has quit [Ping timeout: 258 seconds]
<jhass>
which I avoid for logic expressions
<pipework>
Yeah, I don't think you're quite right about what makes it a side effect. If it's observable outside of the function or expression or modifies some state that makes it so that you can't replace the function/expression with the return of that function or expression.
dc has quit [Ping timeout: 255 seconds]
renderful has quit [Ping timeout: 240 seconds]

holy smokes
<pipework>
Assigning the result of a method call to a local within the expression/function and then doing other stuff doesn't necessarily mean that it's a side effect.
<jhass>
didn't mean it means that, but it can
<pipework>
Yeah it can, but doesn't necessarily mean it does.
<jhass>
point is that avoiding and/or results in side effect free code, which you implied I would have claimed

Your example was confusing, but I think I get your point about it. I don't quite feel like your preferential use of and/or fits what I like, but it makes sense to me.

&& requires learning that it's different from &, whereas if you spoke English, my guess is that the word makes more sense without having to go learn anything about it.

that example is pretty intuitive i'd say, it's just the precedence rules for and and or that aren't very intuitive imo
georgedr_ has quit [Remote host closed the connection]

Yeah, the precedence is that part that I don't think people would intuit because you have to learn it and it likely wouldn't come from prior knowledge. Whereas the same is true about the meanings of && and ||

if i have an integer of say 10000 how could i loop through it and get a per batch of 1000
<aces1up>
so for instance it would be something like 10000.each( 1000 ) do | start, end |

so i can get the start and end indexes of that batch.

twistedpixels what would that look like? was looking to batch it and create a range that i could do work on,.
<twistedpixels>
well I don't know ruby syntax for for loops, but it would be a for loop with an if statement or two that would catch the specific numbers your looking for and store it in a variable
<twistedpixels>
but there could very well be a better way to do it

hi, looking for confirmation (or rebuttal!) that there's no API to ask if an optional keyword argument was actually passed

jhass: I would like to construct a new multidimensional array actually, I want to filter my raw data and then group things and add those grouped data in a new structure.

fxn: that's not unique to optional keyword arguments though, you don't know for regular optional arguments either
<fxn>
jhass: I am rewriting methods that receive hashes, old-school kwargs you know
<workmad3>
fxn: provide sensible defaults for optionar kwargs?
<workmad3>
fxn: or use **kwargs to capture optionals and see if they're present?
<fxn>
workmad3: yeah, but then I loose the explicit naming, which is what I am after
<skroon>
jhass: basically I want to group did: together
<workmad3>
fxn: well, if it's optional, it has a default value... so just make use of the default value and don't care whether it was passed in or not ;)
<workmad3>
fxn: if someone passes in the default value explicitly, it shouldn't make a change to the behaviour of the method, tbh
<jhass>
skroon: .group_by {|hash| hash[:did] }.values if I got that right
<fxn>
workmad3: nope, if the key is not present it has a meaning in my situation, it means certain query param was not sent, and no validations would run, non-setting != setting to nil
<workmad3>
fxn: default doesn't have to == nil
<fxn>
workmad3: I know, there's no other default
<workmad3>
fxn: not even 'whatever: :not_passed'? :P

workmad3: my situation is: if you pass the key, an assignment must happen, if you do not pass the key, the assignment should not happen

Ruby-newbie question. Run a script that required lib/class_y. Have written lib/class_x that inherits class_y and uses "require class_y" in the code. Changing the script in the parent direcoty to call ClassX says it can't find class_y's file.

an alternative would be doing $LOAD_PATH << File.expand_path("../lib", __FILE__) before doing any requires to achieve the same effect

"." in load path is unreliable

the third alternative is using require_relative instead of require which is relative to the current file instead of the current working directory

Generic OOP question. If you have several different children classes that will inherit from the same parent but either override or not use a (method, attribute), should the (method,attribute) be in the parent or just implemented in each child as needed?
<jhass>

<leitz>
jhass, yes. However, it would not be with the (method, attribute)
ghr has quit [Ping timeout: 255 seconds]

?
rkalfane has joined #ruby
<leitz>
jhass, yes. This is coding for a game (Traveller). and 99% of the time a character goes into some military or similar service. The Imperial_Marine class is an example of a Character doing that.
<jhass>
btw ImperialMarine
<jhass>
Imperial_Marine looks silly :P
<leitz>
However, you can have a Character with basic stats but none of the changes.
<jhass>
leitz: so, if there's a common implementation for most of the childs you put it into the parent, regardless if the parent uses it or not and only overrie it in the childs that have a different implementation

<hydrozen>
shevy: yeah indeed
<shevy>
at least on that paste it is consistent

even if verbose :)

I even tried to do stuff like this: def foo_bla; @foo *2; end all on one line
<SpikeMaster>
for lines 27-31 i'd stronly argue for less whitespace. For lines 2-3 i woudlnt' really care either way.
<shevy>
but it conflicted with the rest of my code, so I changed back to not use ; there
<hydrozen>
I think rubocop with its default settings will complain about blank lines after module/class
<waxjar>
i do that if i have a lot of very similar short methods
<hydrozen>
but its configurable..

<waxjar>
and i dont want to define them dynamically so they get documented properly
<hydrozen>
but im afraid my coworker is hard to convince to change his style so i’ll probably just bite the bullet
<hydrozen>
:(
<eam>
hydrozen: introduce something even worse, then compromise
<hydrozen>
his argument was that "if you do put a blank line after your module/class definition, why do you have blank lines around your "private" keyword?
<shevy>
rubocop loves to complain
<hydrozen>
which i think is a completely other thing
<eam>
hydrozen: tell him fine, but he has to indent the blank lines to the appropriate level
<shevy>
hydrozen well you could use private for each individual method too :)))
<shevy>
def foo
<hydrozen>
that was meant to be "if you dont"
<shevy>
end; private :foo

do you use emacs? You could have the trailing "end"s visually appear in your style while actually containing whitespace.
<SpikeMaster>
get to see what you like, but please the whitespace lovers.

Oh, our plan is to expose the api on production environment, we have external developers that work with it
<tejas-manohar>
kaspergrubbe: you guys use 'rspec' or 'rspec-rails'

kaspergrubbe: oh yeah but some parts i assume u dont wanna expose?
_5kg has quit [Ping timeout: 250 seconds]
<kaspergrubbe>
we will expose it behind an admin login :)
<kaspergrubbe>
we use rspec-rails

why would you use core rspec for rails? The helpers in rspec-rails is built for rails testing

kaspergrubbe: true yeah, whats the pt of ur test server? why dont you just deploy to production if all tests pass?
<kaspergrubbe>
Its a bit smoother. Circleci runs specs on all our branches, and when we merge our change into master, the spec-suite is run again, and deployed if passed

The last part is called 'Continuous integration', and I was a bit afraid of it in the beginning, but I really like it now.
<shevy>
wow you really caught kaspergrubbe's attention man
<tejas-manohar>
lol
<tejas-manohar>
kaspergrubbe: yeah makes sense, you know any alternatives to this circleci just trying to investigate how the industry is?

I don't think it makes sense to run it in test. But we have looked at it, but I think there was some integration issues we needed to resolve it before using it

I use it on other projects
