[ruby-talk:444441] encode on nonencoded capable object.

That seems to be the main error but the full error message is [1mTraceback [m (most recent call last): 4: from playground.rb:42:in `<main>' 3: from playground.rb:42:in `p' 2: from playground.rb:42:in `inspect' 1: from playground.rb:42:in `inspect' playground.rb:42:in `inspect': [1mcannot set encoding on non-encoding capable object ( [1;4mArgumentError [m [1m) [m Thanks for your help in advance. Maybe it is because I need to combine the previous values of the types arrays with the additional values and not the previous values are set. What does the error mean and how to fix it? `ptl=[[0,3],[1,5],[2],[3,14],[4,0],[5,0],[6,15],[7,9],[8,7],[9,11],[10,16],[11,6],[12],[13,9],[14],[15,14],[16]] ptl.shuffle() str=ptl[0]+ptl[1]+ptl[2] cr=3 i=0 w=Array.new(2) { [] } until i==3 p ptl[cr] w[i]=ptl[cr] if ((w[i]&str).length()==0) i+=1 end cr+=1 end types=Array.new(19) { [[],[],[]] } pwt=w[0]+w[1]+w[2] types[17]=[[pwt],[str]] for i in 0..(pwt.length()-1) types[pwt[i]]=[[],[19]] end for i in 0..(str.length()-1) types[str[i]]=[[19],[]] end typeslist=Array.new(17) {|i| i } sampstr=Array.new(6) { [] } sampwk=Array.new(6) { [] } for i in 0..types.length()-1 typeslist.shuffle() for j in 0..5 sampstr.push typeslist[j] end for j in 6..12 sampwk. push typeslist[j] end types[0][i]=sampstr.push types[0][i] types[1][i]=sampwk.push types[1][i] types[2][i]=typeslist[13] end p types`

[ruby-talk:444439] [ANN] minitest 5.22.3 Released
by Ryan Davis 13 Mar '24

13 Mar '24

minitest version 5.22.3 has been released! * home: <https://github.com/minitest/minitest> * bugs: <https://github.com/minitest/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * clog: <https://github.com/minitest/minitest/blob/master/History.rdoc> * vim: <https://github.com/sunaku/vim-ruby-minitest> * emacs: <https://github.com/arthurnn/minitest-emacs> minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. "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: ### 5.22.3 / 2024-03-13 * 1 minor enhancement: * MASSIVE improvement of minitest's pride plugin output: Frequencies doubled! Sine waves shifted!! Comments improved!!! Colors rotated!!!! (havenwood) * 3 bug fixes: * Improved wording on Minitest::Test#parallelize_me! to clarify it goes INSIDE your test class/describe. * Minor changes to tests to pass when tests ran with extra flags (eg -p). * Support Ruby 3.4's new error message format.

[ruby-talk:444437] Montreal.rb 2024/03 - Frontend Ruby with Glimmer DSL for Web - Andy Maleh
by Andy Maleh 07 Mar '24

07 Mar '24

The talk video and slides have been posted for the Montreal.rb March 2024 talk "Frontend Ruby with Glimmer DSL for Web" (Ruby in the Browser Web Frontend Framework). YouTube Video : https://www.youtube.com/watch?v=rIZ-ILUv9ME&list=PLRAf4zt5oEjc2mqmEN9m_O0Jo… Google Slides : https://docs.google.com/presentation/d/e/2PACX-1vQVihtMktOEJ-AJWb1a-uyJfpyn… Blog Post Announcement : https://andymaleh.blogspot.com/2024/03/montrealrb-march-2024-frontend-ruby.… 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 in the future, eliminating the conflict between ERB and JS frontend rendering technologies by leveraging highly readable, maintainable, and productive Ruby code isomorphically.
