[ruby-talk:444143] Re: RubyConf 2022 Talk Video for Building Native GUI Apps in Ruby

by Andy Maleh

Andy Nutter-Upham, I just realized I didn't answer this exact question by you in full details (I read the original message on the phone while being quite busy with something a couple of weeks ago, and I somehow missed some of intricacies of your question): "If I missed the documentation and someone knows where it is, I'd love to read it. I think though that since this is a wrapper library there is instead reference to the underlying documentation (whose method names are a bit different, and whose arguments are a bit different) and I find that translation very challenging; especially since glimmer-dsl-libui is not yet complete, so your run into ineffective keywords if you rely on the underlying glimmer docs." Glimmer DSL for LibUI actually does have full documentation for the Ruby API: https://github.com/AndyObtiva/glimmer-dsl-libui#supported-keywords Someone asked me to add the documentation early on when the project was new, and I added it to that person's satisfaction. I hope it's helpful to you too. By the way, I also do mention under the "Original API" section that you could use the LibUI Go documentation as a reference: https://pkg.go.dev/github.com/andlabs/ui But, the most complete reference is the actual C headers: https://github.com/andlabs/libui/blob/master/ui.h And, the C headers are exposed as low-level FFI functions in Ruby as per the Original API (but it's not recommended that you use these method directly of course): https://github.com/AndyObtiva/glimmer-dsl-libui#original-api To give you an example of how the mapping from the C API to Ruby happens, suppose we have this C function: uiWindowSetTitle('My Application') The word before the "Set" or "Get" operation is the control object (e.g. window), and the word after it is the attribute (e.g. title). So, the equivalent of that in the Glimmer GUI DSL: window { title 'My Application' } Basically, we are declaring a window control with one nested attribute of title having the value 'My Application' The C API is procedural and imperative whereas the Glimmer GUI DSL is object-oriented and declarative, better mapping to the way we think of concepts visually while looking at a screen given that you could nest controls (widgets) within each other. If you need further help, do not hesitate to ask further questions at the Glimmer Gitter chat: https://app.gitter.im/#/room/#AndyObtiva_glimmer:gitter.im You shouldn't really get bogged down unless you are missing foundational grounding in software engineering concepts relating to desktop development in general, like MVC (Model View Controller). I've done GUI development professionally in older technologies like Java Swing in the past, and by comparison, Glimmer lets me leapfrog past productivity by 4x at least, sometimes 10x or even more (and it's that much faster in productivity than web development too, so it's great for building quick local apps or tools that don't need the web as it's much simpler, demanding a tiny fraction of web code only). But, it does assume you know MVC (Model View Controller) very well, and it benefits from also knowing MVP (Model View Presenter). Once you get the main ideas behind Glimmer, everything clicks, and things like exact APIs or detailed documentation wouldn't matter much anymore because the way you think with MVC/MVP is you start with the View layer from a GUI mockup to support a specific user workflow, and you either use native controls (like text and button, by looking them up in examples or the docs mentioned above) or you invent your own custom controls (both options are available in Glimmer DSL for LibUI). Of course, the native controls are only as complete as what is implemented by the underlying LibUI library. I know the authors of it are working on adding many new features, like a Tree control, Table sorting listeners, and some other missing features. They will all be added to Glimmer DSL for LibUI in due time when they get released in C LibUI. But, that shouldn't stop someone from learning the library and using whatever is available in it for now, or at least mastering the current features until more features are added in the future (especially given that you could always temporarily polyfill missing features by building your own custom controls if really needed).

[ruby-talk:444290] [ANN] graphics 1.1.0 Released

by Ryan Davis

graphics version 1.1.0 has been released! * home: <https://github.com/zenspider/graphics> * rdoc: <http://docs.seattlerb.org/graphics> Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it: * Uses degrees. * Draws in quadrant 1 (0-90 degrees). * Right hand rule: 0 degrees is east, 90 is north, etc. These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation. Changes: ### 1.1.0 / 2023-07-26 * 3 minor enhancements: * Added anti-aliasing to polygon. Want to add filling at some point. * Requiring ruby 2.7+. Too many changes to ruby internals to try to maintain. * polygon now takes an array of points. * 4 bug fixes: * Fixed a bunch of compiler warnings for ruby struct changes. * Fixed font lookup on linux. (presidentbeef) * Fixed graphics_setup.sh for obsolete build flag on sdl2_image. (NickSchimek) * ruby 3.2: Fixed warning from ruby headers by explicitly removing alloc funcs.

[ruby-talk:444289] [ANN] minitest 5.19.0 Released

by Ryan Davis

minitest version 5.19.0 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: ### 5.19.0 / 2023-07-26 * 2 minor enhancements: * Add metadata lazy accessor to Runnable / Result. (matteeyah) * Only load minitest/unit (aka ancient MiniTest compatibility layer) if ENV["MT_COMPAT"] * 1 bug fix: * Minitest::TestTask enthusiastically added itself to default. (ParadoxV5)

[ruby-talk:444287] [ANN] zenweb 3.10.7 Released

by Ryan Davis

zenweb version 3.10.7 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: ### 3.10.7 / 2023-07-25 * 1 minor enhancement: * Updated to use kramdown 2.x + kramdown-syntax-coderay + kramdown-parser-gfm.

[ruby-talk:444283] [ANN] Learning by Reversing: Native Gems, Part 4

by Mohit Sindhwani

Hi Everyone, I started on a series to learn by reversing a native Ruby gem. Part 4 is now published! This does a deep dive into the makefile that you would use during development and also how it can be made to work properly also on Windows. Part 4 - https://notepad.onghu.com/2023/learning-by-reversing-s1-e4-native-gems/ The first 3 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/ Future posts are planned to go into details like: * The interface between Ruby and C * 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.
