my boss said python is really elegant. i told him that while that might be true, it doesn't have anything on ruby in the way of elegance. he looked at my code and said it had way too many one-liners and he didn't understand anything. i damaged ruby's reputation because i like it so much :-(

I love Ruby, but I've noticed as I've been writing it for longer and longer its idiosyncrasies that I fell in love with end up making my code harder to read, at least for non rubyists, although I've been working to change that some.
<nakilon>
"i damaged ruby's reputation" -- nope, your boss was predamaged
<adam12>
I swear it was mentioned that ostruct is deprecated on the issue tracker. Can't find it right now tho.
<adam12>
Yeah, there was discussion about using a different type of literal. Maybe something like `%struct`.
<adam12>
It would be similar to %w, %i, etc.

I'd probably be OK with `Struct(hash)`. It co-incides with `Kernel.Array` and others.

<kinduff>
+1 on struct hash, it kinda weird to declare and then initialize
<kinduff>
but you wouldn't do that in a class, but you're not using a class
<kinduff>
so
<adam12>
I almost always want to give them a name. Almost. So I can see the hesitation.
<adam12>
Ruby maintains a method cache, and I think it's now per class, but not sure how Struct.new.new works in that regard. It's an anonymous class. So does any other cache get invalidated, like constant lookup? Maybe Kernel.Struct() could work around this somehow; a local cache using the key names as a hash index maybe?

Why is "bundle update" throwing an error for the following? https://pastebin.com/zbEA2puj The constraints seem to be matched
<ruby[bot]>
mbuf: we in #ruby do not like pastebin.com, it loads slowly for most, has ads which are distracting and has terrible formatting. Please use https://gist.github.com

btw assuming you're running an open bundle update, if you're trying bundle update <something> you may need to include nokogiri, bundle update <something> nokogiri

ruby 3.0 breaks my ruby 2 code, would be nice if ruby 3 installed as ruby3..

guess it's time to look into new languages..
<nakilon>
the only noticable change is kwargs and it's a good change, and easy to fix
<nakilon>
no need a pithon/imagemagick digit suffix cancer
<nakilon>
allowing to pass kwargs with * was initially a bad ruby 2 design
jla has joined #ruby
<clemens3>
well, it breaks, it breaks.. just go through each project takes how long..
<clemens3>
maybe libraries need to be upgraded and on and on..
<adam12>
clemens3: How did you install Ruby?
<nakilon>
I believe most of public libraries are already upgraded
<nakilon>
updating Gemfile.lock ersolved version is anyway a normal thing to do time to time
<nakilon>
*resolved versions
<clemens3>
adam12: make install
<nakilon>
and yes, adam12 probably means you had to use rvm or rbenv to have multiple ruby versions installed -- it's a usual practice in most of languages too today
<adam12>
clemens3: `RUBY_BASE_NAME=ruby3 make install` maybe? I've never bothered to try.
<clemens3>
hmm, won't bother, installed 2.7..
<adam12>
¯\_(ツ)_/¯
<leftylink>
I remember there was talk about Ruby IRC bots... a library I used to use doesn't work with Ruby 3 and isn't maintained anymore, too bad! I still have bots that use that library. for that one I guess it'll be okay though, the fix is simple enough
<leftylink>
my distribution does provide a separate ruby 2.7 package for presumably reasons like this
<adam12>
jhass: Yeah! I ended up finding that afterwards.

i've been living under a rock: what's the ruby version manager that everyone likes these days? still rvm?
<havenwood>
seydar: It's split now between asdf, chruby, rbenv, and RVM.
<havenwood>
All work great. ¯\_(ツ)_/¯
<seydar>
i appreciate the alphabetical ordering so as to not show preference
<seydar>
thank you
<havenwood>
seydar: Hahaha.
<weaksauce>
if i had to pick one it would be asdf but i use chruby because it's so simple
<havenwood>
I help maintain chruby and RVM, full disclosure.
<havenwood>
I did use asdf for Elixir the other day.
<weaksauce>
pick one to use and learn today
<weaksauce>
how'd that go havenwood
<havenwood>
seydar: Those four are quite popular then there are others not so much.
<bougyman>
I'm still rbenv. Haven't tried asdf
<havenwood>
weaksauce: I don't still have it installed and just put elixir/bin in $PATH manually >.>

(was setting up LiveBook on DO with my iPad >.>)
SuperLag has quit [Remote host closed the connection]
<weaksauce>
seydar i take it back actually... asdf probably does too much for my liking
<havenwood>
seydar: asdf supports multiple languages, chruby is the simplest with env vars, rbenv is shim land, and RVM is by far the largest but has backports and support for older systems.
<weaksauce>
chruby is like 50 lines of code or something silly like that
<weaksauce>
and it works well
<havenwood>
weaksauce: I'll give asdf another go, I just needed a particular Elixir version hardcoded for a specific spike and had a zip handy.
Ziyan has quit [Quit: My iMac has gone to sleep. ZZZzzz…]
<havenwood>
seydar: rbenv puts a single directory of "shims" in your path, just little programs that redirect to the right Ruby bin/ and gem bin/ directories with env.
<havenwood>
seydar: So rbenv needs to keep those shims up to date. I call it maintaining a garden of shims.
<havenwood>
seydar: The upside is you aren't needing any shell integration. It works with whatever shell, since it's just adding a directory of shims to your path.
<seydar>
i gotta dig into the implenetations of these
<havenwood>
RVM is over 10,000 lines of shell. chruby is just a hundred.
<weaksauce>
fwiw the people that come in here either have issues with rvm or rbenv
<seydar>
i like the divorce from the shell
Ziyan has joined #ruby
<seydar>
i'll look into chruby. it feels like the version manager the amish would use
<weaksauce>
that could either be because it's broken more often or because it's more popular
<havenwood>
Both RVM and chruby are portable shell, so they work with multiple things like bash and zsh but not aesoteric shells and need a separate version for things like Fish.
Cena has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<havenwood>
RVM actually even ships with chruby support, for when fast switching is needed.
<bougyman>
rbenv seems to Just Work, it's why I landed on it.
<bougyman>
I was a long-time rvm user before. Too many rough edges.
<havenwood>
I'd not use MRVM (mini-RVM via chruby that ships with RVM) myself, since you can install with RVM and just use chruby anyways so easily.
Ziyan has quit [Client Quit]
<havenwood>
I used RVM before rbenv before chruby.
<havenwood>
Been with chruby a number of years but we still use RVM as default at work.
<adam12>
Docker!
<adam12>
I don't even bother with version managers anymore. `docker run --rm -it -v $(pwd):/workspace -w /workspace ruby:VERSION bash` is so ingrained in my memory.

i'm trying to get concurrent reads from an sqlite3 DB. do i need to initialize sqlite3 in some way to support this?
jla has joined #ruby
<seydar>
what i'm saying is... i have a []#map call that reads from the DB for each element, but it slowed things down when i tried to introduce parallelism
<havenwood>
seydar: I'd highly recommend the Sequel gem as an abstraction layer that provides a connection pool and so on.
<havenwood>
It's the popular Ruby DB library alongside ActiveRecord.
<seydar>
havenwood: ah, "connection pool" was the keyword I was missing. I was using a single connection and then trying to create multiple processes from there
