i'm hearing a lot of bad things about bundler, because of how outdated bundler is and how it installs everything into ~/.gem, doesn't use semver etc and would require a rewrite to improve. Is there plans for that or are people just going to live with it forever even as ruby and rails evolve?

Has anybody successfull connected an pseudoterminal from pty.open to an xterm? I don't understand the meaning of the xterm-Options -Sccn. The manpage states: "The option value specifies the last few letters of the name of a pseudo-terminal to use in slave mode, plus the number of the inherited file descriptor." however, i cannot determine the correct number of the inherited file descriptor. If i choose one of the

What's weird about rails to me is that i don't see it requiring much Ruby code to be written by me. It seems 99% "framework" from the code bases i'm looking at
<mehwork>
is that normal? To not write much ruby logic when writing a web app? I mean like functions are 3 lines ling, or are mostly declarative. When I do see an if/else block its like one statement in each if and else

serard: I have not tested this method, but the method `.deep_merge` takes 2 argument, one hash and another, and you can pass a block (a lambda), which takes 3 values (key, value_one, value_two), and you return the value to take.

the block is used to resolve conflicts

I don't know, it looks it is a class method, so it takes as arguments the hashes

guys, when I use `bundle exec sidekiq -r ./worker.rb` it works good. Tasks in sidekiq themselves and they get done. However I would like the application to run together with the application web, so i added line in config.ru -> `require_all worker.rb` . App web works, sidekiq gui works, I see tasks in cron but the tasks do not get done. Any idea?

mehwork: How is Bundler outdated? It's updated all the time and continues to be copied by other languages.
<havenwood>
mehwork: Installing into ~/.gem is a RubyGems setting which can and is often changed. What's the criticism?
<havenwood>
mehwork: How does Bundler not use semver?
jenrzzz has joined #ruby
<havenwood>
mehwork: You can use RubyGems directly without Bundler if you prefer. I have my own nits with Bundler, but the criticisms you list aren't legitimate, just FUD.
<havenwood>
mehwork: It's odd to pick a maintained piece of software that Yarn, Cargo, and other best in class new offerings copy from and pose it as a drag on Rails.
<havenwood>
It's not.
<havenwood>
If you want me to rant about Bundler, happy to, but being maintained and installing to RubyGems default location by default aren't issues.

I'm not even sure how one would identify it as "outdated". It Just Works™ with Rails, as far as my experience is concerned.

<mehwork>
the biggest con i'm seeing so far is that i don't see people having to write much code in rails. I know that sounds like a pro, but to me it looks like the framework is doing 99% of the work for you and my programming skills might get weak
* nakilon
hides in bunker
<adam12>
O_O
al2o3-cr has quit [Ping timeout: 256 seconds]
<adam12>
It definitely doens't do the 99%. Take a look at Gitlab. It's an insane number of lines, + Rails.
<adam12>
It takes a way a ton of boilerplate tho; and if boilerplate grows your programming skills, you should be having a leg day somewhere too.
<adam12>
mehwork: Have you written any Ruby or Rails yet? I wouldn't make a decision just by some nerds on IRC.
<adam12>
(havenwood is the nerd btw)
coniptor has joined #ruby
<adam12>
havenwood: I didn't know Yehuda had a part in yarn. That makes sense.
<mehwork>
adam12: not yet beyond the basic tutorials. But even looking at rails code bases i haven't seen much logic. Is everything mostly declatrive, and with very simple ternaries?
<mehwork>
i come from python/javascript so maybe i'm not used to that level of abstraction
<adam12>
mehwork: A lot of people like small methods. So a lot of conditionals might live in a method with a name.
<mehwork>
most of the rails code i'm seeing everywhere so far is a thousand 1-3 liner def statements
<mehwork>
ok
<adam12>
mehwork: It's easy to write code. It's much easier to _read_ code.
<mehwork>
small methods aren't necessarily a bad thing, though can get daunting
<adam12>
For Rails? Maybe the CRUD stuff is small, but that's because it just extracts the boilerplate. Work smarter not harder and all that.
weaksauce has joined #ruby
<adam12>
Yeah. Small methods arent' a panecea, and they _can_ become hard to follow. But so can a large method with a ton of branches. So you kinda pick your poison.
<mehwork>
true
<mehwork>
i'm mostly just trying to find one place where some cool ruby code is being used in a rails code base. By cool i mean stuff i mean "normal" stuff i'm used to seeing like in JS or Python code, like functional stuff, storing stuff in a hash table, and
<mehwork>
all that
<adam12>
With regards to bundler; it's definitely not perfect and not without it's warts, but it has steady progress, people paid to work on it, etc.
<mehwork>
maybe it's too magical for me
<adam12>
mehwork: What's magical?
<mehwork>
not explicit enough to follow the logic
<mehwork>
just a lot of small methods like we said. Having to follow all of them to try to figure out what's going on and how things actually work
<adam12>
Do you actually care about all of them tho? A small method means you can care about a small piece.
<mehwork>
iow, not seeing many 'if' statements
<mehwork>
adam12: normally i can understand an entire code base
<adam12>
Branches are evil. Not seeing `if` statements is good, not bad. Sandi Metz has some videos on this topic, but you want to generally see more flat shapes when squinting at code, not huge swaths of indentation.
<mehwork>
but i'm looking at a lot of ruby code and not really understanding anything but a tunnel vision idea of what might be going on, but that is a little scary in terms of "am i putting this in the right place?" "what happens if there's a bug with something underlying?"
jla has quit [Ping timeout: 264 seconds]
<mehwork>
i just set up a rails json api with the '--api' flag and now i have no idea what to do. The documentation ended at that
<mehwork>
they give you some code generation commands and then stop, almost like it's a secret club. I'm almost waiting for the "now buy my ebook" spam link to actually learn it lol
<mehwork>
any pointers to actual learning resources would be appreciated. So far i'm lost
<havenwood>
mehwork: I'd recommend starting by taking a few minutes to make a very basic Rack app. (Bonus points for adding a trivial Rack middleware.) Then port your trivial Rack app to Roda and add a plugin or two for something your API might need.
<adam12>
mehwork: Everything from the regular guides would still be applicable, sans the usual stuff that would render to a browser (like views). So after doing --api, I'd just circle back to any of the other guides.
<mehwork>
see that type of thing is just more complicated. The _only_ reason i was even remotely attracted to rails is that it's supposed to be friendly/easier.
<havenwood>
mehwork: Rails is a very complex Rack app that gives you a great head start if you're making something like Basecamp or Hey.
<havenwood>
mehwork: Rails is lovely.
<mehwork>
and so far it's "learn what 5 billion classes do" and now "use some other framework first"
pgib has joined #ruby
<havenwood>
mehwork: Roda might be a better fit for a simple API like it seems you're targeting.
<mehwork>
i'm not a fan of ORMs which is anther main blocker for me
<mehwork>
i already know sql well, so it feels weirdd having a framework do queries for me
<mehwork>
especially not knowing if they're generating decent sql
<havenwood>
mehwork: The Ruby ORMs are happy to spit out the SQL they're generating.
<mehwork>
i like the ruby language itself though, but since i mostly work in backend/web stuff it seems ruby wants to force these types of magical frameworks on people
<havenwood>
mehwork: Sequel can be used pretty close to the metal, but no complaints from me if you prefer writing SQL as the gods intended.
<mehwork>
ok, i'll have some more exploring to do first i guess
<alexherbo23>
when testing a model, creating an instance, do I have to know the property such as the name, etc. for testing?
<alexherbo23>
also, factory bot is used for creating, but I need to create instance (not persisted yet in the database), such as testing .new with constructor parameters and block. how can I avoid managing the attributes, like factory bot allows?
<alexherbo2>
I'm also not sure how to test my #reload method (the method returns a fresh instance sync from the database (unlike activerecord which modify in place the record))
<phaul>
It's better not to put too much behaviour in subjects and lets, it can lead to confusions. especially that it memoizes. subject and let should just produce objects for test not behaviour
<nakilon>
the race for shortening the code can go infinitely far but should have an end
<phaul>
except if it's an "endless" method :)

using .0.0 releases in things are unstable
