[ruby-talk:444281] Seeking learning resources/advice
by sdario＠fastcase.cl 19 Jul '23

19 Jul '23

Hello community, how are you all doing? My name is Sebastian, I'm 23 years old and I'm from Santiago I don't have any professional qualifications in computer science or informatics but I studied electronics and have a strong foundation in various basic concepts and tools/languages Today I'm writing to ask you all for learning resources. I'm looking to learn and practice Ruby and all its different aspects, from the very basics up to writing professional level code. I want to learn best practices from the start, so that no matter what the current level I'm on my learning curve, I can write code using the latest advances and techniques, so that whatever I'm programming is done in the most professional and efficient way possible. I don't have a lot of expertise but I'm looking to start my journey with a solid foundation, and I decided to write this to the most appropriate group of people. Greetings from Chile!

[ruby-talk:444275] [ANN] ruby_parser 3.20.3 Released
by Ryan Davis 11 Jul '23

ruby_parser version 3.20.3 has been released! * home: <https://github.com/seattlerb/ruby_parser> * bugs: <https://github.com/seattlerb/ruby_parser/issues> * rdoc: <http://docs.seattlerb.org/ruby_parser> ruby_parser (RP) is a ruby parser written in pure ruby (utilizing racc--which does by default use a C extension). It outputs s-expressions which can be manipulated and converted back to ruby via the ruby2ruby gem. As an example: def conditional1 arg1 return 1 if arg1 == 0 return 0 end becomes: s(:defn, :conditional1, s(:args, :arg1), s(:if, s(:call, s(:lvar, :arg1), :==, s(:lit, 0)), s(:return, s(:lit, 1)), nil), s(:return, s(:lit, 0))) Tested against 801,039 files from the latest of all rubygems (as of 2013-05): * 1.8 parser is at 99.9739% accuracy, 3.651 sigma * 1.9 parser is at 99.9940% accuracy, 4.013 sigma * 2.0 parser is at 99.9939% accuracy, 4.008 sigma * 2.6 parser is at 99.9972% accuracy, 4.191 sigma * 3.0 parser has a 100% parse rate. * Tested against 2,672,412 unique ruby files across 167k gems. * As do all the others now, basically. Changes: ### 3.20.3 / 2023-07-11 * 2 minor enhancements: * Added Parser#in_argdef and integrated into 3.x parsers. * Improved tools/munge.rb to handler MRI 3.2 output * 2 bug fixes: * Fixed process_dots to properly deal with paren-less forward_args. (eric1234) * Fixed tools/ripper.rb to properly print ripper sexp at the end

by Andy Maleh 09 Jul '23

09 Jul '23

Glimmer DSL for LibUI 0.0.8 has been released with a new feature called Composite Shape (already in Glimmer DSL for SWT), which enables building new visual concepts by aggregating multiple smaller shapes within a parent composite shape using relative positioning and inherited `fill`/`stroke` colors. https://raw.githubusercontent.com/AndyObtiva/glimmer-dsl-libui/master/image… Blog Post Announcement: https://andymaleh.blogspot.com/2023/07/glimmer-dsl-for-libui-composite-shap… GitHub: https://github.com/AndyObtiva/glimmer-dsl-libui RubyGem: https://rubygems.org/gems/glimmer-dsl-libui Change Log: 0.0.8: - Support `composite_shape` keyword (alias: `shape`) as aggregate (composite) shape that can have arbitrary shapes, text, transforms underneath, which inherit its `fill`/`stroke` colors and `transform`. `composite_shape` also supports nesting mouse listeners, which check mouse click point containment against all nested shapes automatically. - New `examples/basic_composite_shape.rb` with use of `shape` + drag and drop support for moving shapes and click support for changing shape colors - Invert `Glimmer::LibUI::ControlProxy::KEYWORD_ALIASES` to enable adding multiple aliases per keyword - Support `Glimmer::LibUI::Shape::KEYWORD_ALIASES` to enable adding multiple aliases per keyword - Small update for `examples/button_counter.rb`

[ruby-talk:444267] [ANN] minitest-bisect 1.7.0 Released
by Ryan Davis 08 Jul '23

08 Jul '23

minitest-bisect version 1.7.0 has been released! * home: <https://github.com/seattlerb/minitest-bisect> * rdoc: <http://docs.seattlerb.org/minitest-bisect> Hunting down random test failures can be very very difficult, sometimes impossible, but minitest-bisect makes it easy. minitest-bisect helps you isolate and debug random test failures. If your tests only fail randomly, you can reproduce the error consistently by using `--seed <num>`, but what then? How do you figure out which combination of tests out of hundreds are responsible for the failure? You know which test is failing, but what others are causing it to fail or were helping it succeed in a different order? That's what minitest-bisect does best. Changes: ### 1.7.0 / 2023-07-06 * 1 major enhancement: * Extend bisect_methods to do "inverse" run (eg false positives) via -n=/RE/ argument. * 4 minor enhancements: * Added example_inverse.rb * Collapsed examples from directories to individual files. * Refactor: push command generation from #run down to #bisect_methods. * build_files_cmd no longer calls reset (zero effect change). * 4 bug fixes: * 100% documentation coverage. * Fix server process ID to be a string to match rest of args. * Fix shebang cmd on bin/minitest_bisect. * Print known bad methods with found culprit methods in final run.
