[ruby-talk:444327] [ANN] Learning by Reversing: Native Gems, Part 6
by Mohit Sindhwani 27 Sep '23

27 Sep '23

Hi Everyone, I started on a series to learn by reversing a simple native C Ruby gem. Part 6 is now published! It looks at how to benchmark the native gem. Link to Part 6: https://notepad.onghu.com/2023/learning-by-reversing-s1-e6-native-gems/ The whole series is available at: https://notepad.onghu.com/2023/learning-by-reversing-s1-native-gems/ * Part 1 - This covers the background to the gem we explore Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e1-native-gems/ * Part 2 - This goes into the details of how ruby loads the native gem and extension (and includes a nice sequence diagram of how all the bits happen together) Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e2-native-gems/ * Part 3 - How do we ensure that we have everything and that it actually gets built at installation? Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e3-native-gems/ * Part 4 - Understanding the development Makefil Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e4-native-gems/ * Part 5 - The Ruby C/API Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e5-native-gems/ There are more parts planned, including documenting the code, running the specs and enhancing the gem. Comments on the posts or the plans welcome. I'm @onghu on Twitter or @onghu@ruby.social on Mastodon if you're on either. Best regards, Mohit.

[ruby-talk:444323] [ANN] minitest 5.20.0 Released
by Ryan Davis 06 Sep '23

06 Sep '23

minitest version 5.20.0 has been released! * home: <https://github.com/minitest/minitest> * bugs: <https://github.com/minitest/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * 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: ### 5.20.0 / 2023-09-06 * 1 minor enhancement: * Optionally allow autorun exit hook to remain active in forked child. (casperisfine)

[ruby-talk:444322] [ANN] zenweb 3.10.8 Released
by Ryan Davis 30 Aug '23

30 Aug '23

zenweb version 3.10.8 has been released! * home: <https://github.com/seattlerb/zenweb> * bugs: <https://github.com/seattlerb/zenweb/issues> * rdoc: <http://docs.seattlerb.org/zenweb> Zenweb is a set of classes/tools for organizing and formating a website. It is website oriented rather than webpage oriented, unlike most rendering tools. It is content oriented, rather than style oriented, unlike most rendering tools. It uses a rubygems plugin system to provide a very flexible, and powerful system. Zenweb 3 was inspired by jekyll. The filesystem layout is similar to jekyll's layout, but zenweb isn't focused on blogs. It can do any sort of website just fine. Zenweb uses rake to handle dependencies. As a result, scanning a website and regenerating incrementally is not just possible, it is blazingly fast. Changes: ### 3.10.8 / 2023-08-30 * 1 bug fix: * Fixed configuration of no_line_numbers for kramdown v2 changes

Hello, Is () supposed to allow multiple statements in it? Documentation is not explicit about it. https://docs.ruby-lang.org/en/master/syntax/control_expressions_rdoc.html#l… E.g. puts((:ignore; :x)) # x puts (:ignore; :x) # Otoh, raises an unexpected semicolon error I'm looking at using () in a while loop's condition but please just consider that as an extra info. I need an official answer on my query above. -- konsolebox

28 Aug '23

Mattias Velamsson recently shared a beginner's tutorial for making a GUI (Graphical User Interface) in Ruby titled "Ruby GUI with Glimmer". It provides a step-by-step code walkthrough that produces a full-fledged web-API-driven table-based business application. It uses various gems and APIs like glimmer-dsl-libui, dotenv, Net::HTTP, URI, JSON, and the Exchange Rates Data API. https://dev.to/smackdh/ruby-gui-with-glimmer-2fkh

[ruby-talk:444308] [ANN] Learning by Reversing: Native Gems, Part 5
by Mohit Sindhwani 16 Aug '23

16 Aug '23

Hi Everyone, I started on a series to learn by reversing a simple native C Ruby gem. Part 5 is now published! This does a deep dive on understanding how to use the Ruby C API from a C file.It shows how the Ruby C API works & how it accesses Ruby data, raises exceptions, checks function arguments and so on. Link to Part 5: https://notepad.onghu.com/2023/learning-by-reversing-s1-e5-native-gems/ The first 4 parts are also online on my blog: * Part 1 - This covers the background to the gem we explore Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e1-native-gems/ * Part 2 - This goes into the details of how ruby loads the native gem and extension (and includes a nice sequence diagram of how all the bits happen together) Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e2-native-gems/ * Part 3 - How do we ensure that we have everything and that it actually gets built at installation? Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e3-native-gems/ * Part 4 - Understanding the development Makefil Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e4-native-gems/ Future posts are planned to go into details like: * Documenting the code * Running the specs and the performance benchmark * Enhancements: - Providing an executable - A gem that also works on JRuby - Making the gem ractor friendly - Patching an existing gem rather than a new module Comments on the posts or the plans welcome. I'm @onghu on Twitter or @onghu@ruby.social on Mastodon if you're on either. Best regards, Mohit.
