[ruby-talk:444426] Upcoming Montreal.rb Talk on March 6, 2023: "Frontend Ruby with Glimmer DSL for Web"
by Andy Maleh 23 Feb '24

23 Feb '24

I will be giving a Montreal.rb Ruby meetup talk titled "Frontend Ruby with Glimmer DSL for Web" on Wednesday, March 6 2023 at 7pm ET (doors open at 6:15pm ET). The event will be hosted at Lexop (506 McGill St Suite 400, Montreal, Quebec, Canada). The talk description is below. In my opinion, this is the most exciting Ruby topic in 2024 for doubling productivity and halving cost and time in developing and maintaining Rails Frontends compared to using inferior JS technologies like React, Angular, Vue, Svelte, etc... I strongly believe this will be the most important Ruby investment in 2024. Anyone who ignores it will be stuck in what feels like the Ice Age of Frontend Development by comparison, kinda like riding horse carriage compared to driving a Ferrari. RSVP : https://www.meetup.com/montrealrb/events/298445180/ Talk Description : "Rubyists would rather leverage the productivity, readability, and maintainability benefits of Ruby in Frontend Web Development than JavaScript to cut down development cost and time by half compared to using popular yet inferior JavaScript frameworks with bloated JavaScript code as per Matz's suggestion in his RubyConf 2022 keynote speech to replace JavaScript with Ruby. Fortunately, this is possible in 2024! This talk is a continuation of the previous Montreal.rb talk "Intro to Ruby in the Browser", which ended by promising a new way in the future for developing Web Frontends that would completely revolutionize the way we think about and do Frontend Development using Ruby instead of JavaScript. The future is now!!! The simplest, most intuitive, most straight-forward, and most productive Frontend Framework in existence is here! It is an open-source Ruby gem called Glimmer DSL for Web. Think of Glimmer DSL for Web as the Rails of Frontend Frameworks. With it, you can finally live in Rubyland in both the Frontend and Backend on the Web! That opens up the door to ideas like rendering Frontend Components in the Backend as Server Components, eliminating the conflict between ERB and JS frontend rendering technologies by leveraging highly readable, maintainable, and productive Ruby code isomorphically."

[ruby-talk:444415] [ANN] minitest 5.22.2 Released

"I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply. Changes: ### 5.22.2 / 2024-02-07 * 1 bug fix: * Third time's a charm? Remember: 'ensure' is almost always the wrong way to go (for results... it's great for cleaning up).

[ruby-talk:444411] Code analisys
by Peter Hickman 06 Feb '24

06 Feb '24

I have some old code to work with that is more than a little over engineered. A lot of the code is a method in class A calls a method in class B which calls a method in class C, turtles all the way down and mostly class methods and not instance methods. But most of these methods pretty much do nothing but call methods in another class. I swear there are loops in there too! Is there a tool that would allow me to graph this so I might see where the actual work is being done and shorten these branches?
