I can't install ruby 3.0.2 on my mac 10.13; neither via rbenv nor installing from source. both fail with this error: "./include/ruby/internal/scan_args.h:264:48: error: use of undeclared identifier 'fmt'; did you mean 'fma'?". Is there a way to get it to work?

kluk: Intel or M1?
<adam12>
kluk: Actually, looking at 10.13 makes me think an Intel.
<adam12>
kluk: I'd try compiling other versions, one by one, starting from 3.0.1, and see if you can compile any down to the 2.5 branch. If you can't, it might be environment specific, but if it's 3.0.2 only (or 3.x only), it might be worth a bug report to bugs.ruby-lang.org.

Hello, is it acceptable in Ruby to have a method return different types, depending on a conditional inside? Or does the caller always expect that it will always return the same object type?
<adam12>
Guest74: You can return different types, but I'd say that violates Principle of Least Surprise, so you should at least consider what you're doing when you choose to do that.
<Guest74>
Thanks @adam12, my method has an (async=false) param, so will either return the actual result or a reference to the job. I'm guessing best practice would be to have foo() and foo_async() instead?
<adam12>
Guest74: I'd probably do that, unless you could find a way for both types of return values to share the same API.
<adam12>
Guest74: ie. do you eventually call foo.value for an async call? if that's the case, you could return an object that has a value method that is synchronous.
<Guest74>
Good point. Thanks! adam12
<adam12>
Guest74: If the API is more complex then that, I'd personally split the methods.
<Guest74>
Yeah, I'll split avoid extra unnecessary complexities.
<Guest74>
Yeah, I'll split and avoid extra unnecessary complexities.
<nakilon>
lots of stdlib methods return different types, it's ok
<nakilon>
at least when it can return Nil

is there a gem install command that will install the version of bundler defined in Gemfile.lock or do I have grep/parse Gemfile.lock to get that info?
<adam12>
crankharder: I don't believe there is one.
<crankharder>
gem install bundler -v $(grep "BUNDLED WITH" -A 1 Gemfile.lock | tail -n 1) should work, but seems like there should be a more better way

i think rvm has binaries for osx you might be able to use
<kluk>
I'd love some binaries
<rg>
rvm offers them afaik
<kluk>
I know nothing about rvm but I'll install it right now. is there something important like a flag I need to know in order to get binaries?
<rg>
it's default behavior, if it finds it'll use them
<kluk>
thank you!

I dislike how in order to use some array methods on a range, I have to explicitly call #to_a on the range
<seydar>
I think my code looks ugly when I have to do (1..10).to_a.combination(4).etc.etc.
<leftylink>
yeah or sometimes I want a random letter so I'll try (?a..?z).sample ... too bad for me
<nakilon>
[*1..10]
<nakilon>
though it's weird that there is implicit casting of everything to String, but not Range to Array

Hello guys! I'm getting creazy with this: using a form_with in a rails application, the `form.select` isn't accepting the classes I want it to have, for instance, i do this: `<%= form.select :user_id, User.all.collect { |user| [user.name, user.id], class: 'form-control' %>` and get a simple select, without the class, can you, guys, help me?
<kenliten>
Thanks in advance!

kenliten, does the html it generates look weird or just lack it completely?
<newton>
or you may need to pass that class param as part of a separate hash: f.select(:user_id, ..., { class: 'form-control' })

newton, it looks good, just as I've never passed the class away, and the second one, I've already tried it that way, and doesn't work either
<kenliten>
I really found a fix, but works really weird, fixed the look with inobstrusive js, when charge the form, js look for every select in the form and assign the classes I need, the problem is that isn't work when I get the form asynchronously or render it from other view
<kenliten>
That's why I'm looking for a more appropriated solution
<kenliten>
I know, this channel isn't rails focussed, but I didn't find one like that

kenliten shouldn't that be in the html_options part?
<weaksauce>
there's an options hash and a html_options hash
<kenliten>
Yes, that's the only one way I didn't try before, let's check and tell you what, thanks
<weaksauce>
also, the code above is missing the closing } on the block
<kenliten>
I feel so idiot right now, Haha, done, it works! Just passed an empty hash as options, and then a new hash with the classes. So, finally solved it like this: `<%= form.select :vehicle_class, vehicle_sizes, {}, {class:'form-control rounded-0 form-control-sm'} %>`
<weaksauce>
awesome! :)
<kenliten>
Thank you so much weaksauce
<kenliten>
I'll try to be more diligent when read the docs again
<weaksauce>
hopefully you won't forget the html_options lesson any time soon

Once I learn something, It becomes hard to forget to me, but this one, I'm writing it on a stone...
