hmm. most of the Ruby I write these days is code that helps me calculate something for a game. like the possible ways to achieve an objective, or how to maximise a certain value
<leftylink>
like, you'll recall that a few weeks back I wrote code that was looking for a prime < 100 that is the sum of six primes
<leftylink>
you guessed it, that was for a game
<leftylink>
I don't even remember what game anymore

adam12, mooff: If you remember the "ruby interpreting arguments in a shebang" issue I had lately, I decided to keep the name rubyexec. It's useful that rubyexec is also usable to scripts containing special options in the shebang.

what does one use these days in order to access a mariadb database (and, ideally, also mysql databases)
<TomyWork>
basically the steps I put in my build script that worked on my old machine a year ago no longer work
<TomyWork>
but I also updated the gem from 2.8.1 to 2.9.1, both of which are older than this entire project, so idk what's going on
<TomyWork>
oops, figured it out. I was previously using mysql2, not mysql...
orbyt_v10 has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<adam12>
TomyWork: Sequel for everything.
<adam12>
TomyWork: You'll still need an adapter for mysql/mariadb. Sequel supports mysql2, mysql, and mysql-ruby.
<adam12>
ruby-mysql rather
<TomyWork>
oh i thought you meant mysql2 is a sequel for mysql :D
<adam12>
You could also try trilogy which is from Github. I've never used it.
<TomyWork>
nah I'm not gonna do a major architectural overhault right now
<adam12>
If you're having an issue building mysql gem, likely can't find dev headers.
<adam12>
Share that error and maybe we can help with that.

I'm still chewing on the problem I had yesterday. I installed the prometheus-client gem but I can't "require 'prometheus/middleware/collector'". I get "LoadError: cannot load such file -- prometheus/middleware/collector"
<TomyWork>
I'm doing this in my classic sinatra application, not in config.ru
<TomyWork>
although upgrading sinatra to 4.0.0 required me to add the rackup gem as well, so I guess sinatra is based on rackup, too, now?
<TomyWork>
the error I got without it was 'Sinatra could not start, the "rackup" gem was not found!'
<adam12>
TomyWork: rack 2 to 3 separated rackup from rack.
<adam12>
TomyWork: So now you need rack and rackup gems if you want to use rackup.
<adam12>
Are you using Gemfile / bundler?
<TomyWork>
I dont know if i want eithe rack or rackup. I want to add a prometheus metrics endpoint. prometheus middleware from the prometheus-client gem seemed like the easiest way
<adam12>
TomyWork: How do you run your app?
<adam12>
And do you just `require "sinatra"` at the top?
<TomyWork>
bundle exec ./app.rb and yes
<TomyWork>
"== Sinatra (v4.0.0) has taken the stage on 54321 for development with backup from WEBrick" <-- shouldnt it say something about rack if it's using rack?
<adam12>
You added prometheus-client to your Gemfile?
<TomyWork>
oh i get it, rack is a framework and you can use any application server with it, including webrick
<adam12>
Rack is just the translation layer between Sinatra and WEBrick (and others)
<adam12>
Yeah
<adam12>
A long time ago, every web framework had to build support for each web application server
<TomyWork>
yes I added prometheus-client to my Gemfile
<adam12>
Then leah2 made Rack, which just unifies the interface.
<TomyWork>
neat
<adam12>
I'm surprised you're getting the error about no such file then.
<TomyWork>
me too
<TomyWork>
gem 'prometheus-client', '~> 0.4.2'
<TomyWork>
oof why is this old version the first result on google
<adam12>
That version is old
<adam12>
Ooh. I missed it. Yes. Current is like 4.x
<TomyWork>
yeah 4.4.2
<TomyWork>
yay, works now
<TomyWork>
just one problem: no metrics :D
cappy has quit [Quit: Leaving]
<TomyWork>
oh nm, that was just because /metrics was literally the first request
<TomyWork>
ok, now I'll just deploy this, throw a prometheus annotation on it and call it a day. grafana dashboard some other day :)

<vanfanel64>
adam12, no just a test to see how 0 "0", "" can be treated as false like in many other scripting languges
<vanfanel64>
I think I broke the bot
<adam12>
vanfanel64: I'd just define a Boolean method that does the coercion for you. You can define it on Kernel and it would be everywhere. It's kinda faux-pas because you're clobbering the global namespace but it might work for you.
orbyt_v10 has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<vanfanel64>
adam12, thanks, though I am not sure where/what is being clobbered though. Do you mean just be declaring x? That was just for a simple test

vanfanel64 what are you actually trying to do?
<weaksauce>
in ruby there are only two falsey values ... nil and false.
