Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

CLI tools at Aha!
Ruby has always been a great general-purpose scripting language and is often used to create command-line utilities. Many of these use the excellent Thor gem to parse command-line options, but there's no escaping one fact: command-line utilities just aren't interesting. Never have been, never will be.

How to Build Your Own Rails Generator
All public methods in the generator will be called one after the other. Private methods will not be called but are available in your public methods like regular Ruby classes.

Seeking recommendations or suggestions for learning Ruby to maintain the home directory?
I will add that if you want to develop a CLI tool that gives you various commands that you can run, I would have a look at something like thor to keep it organised and documented. But this is completely unnecessary as a first step - you can simply create a Ruby file that does a thing you want and invoke it directly.
- A more ruby-ish command line parsing - design idea

Bootstrapping with Ruby on Rails Generators and Templates
Not to be confused with generator functions (which you might be familiar with from Python or Javascript), Rails generators are custom Thor commands that focus on, well, generating things.

Building a Dot Matrix Animator
I wanted to provide a command-line interface for the user that was easy to use, and I also wanted to provide the flexibility with the options used to render the animation. After looking around online I found that Thor was a good tool to utilize. It allowed me to easily create a number of options that make this program much more versatile. An example below shows how a user can select which folder the source images are in, as well as what the background and foreground colors should be:

Move over Rake, Thor is the new King
I've used Thor a lot, but it's kind of terrible. It uses a custom non-POSIX-compliant option parser (ex: method_option :list, type: :array -> --list one two three, where as the POSIX way is --list one,two,three or --item one -- item two --item three) and will not error on unknown options or exit with -1 when not enough args are given. If you want a better CLI library, checkout dry-rb, command_kit, or cmdparse.

Ruby for replacing Unix shell scripts? (eg. a better Perl)

16 Best Ruby Frameworks For Web Development [2024]
Cuba takes help from a lot of other technologies to bring the best of everything. For example, the responses in Cuba are the optimized version of the Rack responses. The templates are integrated via Tilt and testing via Cutest and Capybara.

I am going to use a browser based testing tool called Playwright (But you could use Capybara, or Selenium WebDriver etc.).

Building GitHub with Ruby on Rails
Even as a much smaller team, building Heii On-Call [0] as a lightweight alerting/monitoring/on-call rotations SaaS based on Ruby on Rails has basically been a pleasure!
And as the article highlights, perhaps the key reason for smooth deployments and upgrades is that the CI testing story is so, so good: RSpec [1] plus Capybara [2] for us. That means we have decently extensive tests of just about all behavior. The few small Rails and Ruby upgrades we've done have gone quite smoothly and confidently, with usually just a few non-Rails gem dependencies needing to be manually updated as well.
The "microservices" story is where we've pulled in the Crystal programming language [3] to great effect. After dabbling with Go and Rust, we've found that Crystal is truly a breath of fresh air. Crystal powers the parts of Heii On-Call that need to be fast and low-RAM, specifically the inbound API https://api.heiioncall.com/ and the outbound HTTP(S) prober background processes. I've ported some shared utility classes from Ruby to Crystal almost completely by just copy-and-pasting ___.rb to ___.cr; porting the tests for those classes was far more onerous than porting the class code itself. (Perhaps another point of evidence toward the superiority of RoR's testing story...)
The front-end story is nice but just a bit weaker. Using Hotwire / Turbo successfully, but I have an open PR to fix a fairly obvious stale cache bug in Turbo [4] that has been sitting unloved for nearly a month, despite other users reporting the same issue. I'm hopeful that it will get merged in the next release, but definitely less active than the backend side.
For me, the key conclusion is that the excellent Ruby on Rails testing story is what enables everything to go a lot more smoothly and have such a strong foundation. I'd be curious if any GitHubbers can talk more about whether they too are using Rspec+Capybara or something else? Are there internal guidelines for test coverage?

Using Capybara to test responsive code
Engineering at Aha! focuses on using and improving the Capybara test framework. We have added many helpers and additional functionality to make working with Capybara easy. Testing at mobile widths is another chance to improve our testing tooling. Here is the incremental approach that we used to add mobile testing helpers.

Minitest vs. RSpec in Rails
Since the Capybara library drives the underlying tests, Minitest also has the same syntax.
- Is it a common practice to test JS code in a browser instead of Node.js?

Testing Strategies For Microservices
We can write component tests with any language or framework, but the most popular ones are probably Cucumber and Capybara.

From partials to ViewComponents: writing reusable front-end code in Rails
The nice thing about partial templates is that templates are unit-testable with View specs (or similarly in Minitest) and the rendered output can even be verified using Capybara matchers.

Tip: if you're changing all your form_for to form_with, take the opportunity to make sure all forms are being tested.
To piggyback: This would be a type of browser test, so you would want to use something like Cypress (https://github.com/testdouble/cypress-rails) or Capybara (https://github.com/teamcapybara/capybara). RSpec has a good integration with Capybara. Cypress is JS-based so it will require some additional config.

Validating Views with Capybara Queries
When you write a system test (or, as we prefer, a system spec) with Ruby on Rails, you're exercising the whole stack from the point of view of the user. So, naturally, you have to do things like make sure that certain elements are on the page and work as you expect when you click on then, type in them, and drag them around. Capybara works exceedingly well for this, giving you a lovely API for querying HTML.
