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: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

[ruby-talk:444316] Multiple statements inside ()
by konsolebox 30 Aug '23

30 Aug '23

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

[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.

[ruby-talk:444307] Every True Rubyist Builds Their Own Code Editor in Ruby!
by Andy Maleh 15 Aug '23

15 Aug '23

"Every self respecting Senior Software Engineer out there should build their own code editor, even if just as a toy app to later be discarded in favor of another code editor (though they might grow to prefer their own). And, if they are Rubyists, they should build their code editor in Ruby (whether using MRI Ruby, JRuby or Opal Ruby). If you think of yourself as a Ruby Senior Software Engineer, but cannot build your own code editor in Ruby, there are serious holes in your skillset!! Explore Glimmer libraries for many Ruby options to help you start the code editor building challenge and journey."

[ruby-talk:444294] Alternative logging solutions
by Peter Hickman 04 Aug '23

04 Aug '23

Presently our applications use the standard Logger package that comes with Ruby and it works just fine. We use it in conjunction with the standard unix logrotate. Up to now everything has been working as expected Until the logrotate hit in the middle of some significant processing and a client had a query. What we found was a 2 second gap in the logs. The end of the old log was the start of a transaction and the start of the new log was the end of a completely different transaction. So we have lost partial information from two transactions and it is possible that there was at least one transaction between these two that was lost completely. Each transaction takes around 1 second to process, sometimes less This time it was not too big an issue and there were other ways to investigate the problem Is there some other way of logging that is even less likely to lose data?

[ruby-talk:444293] [ANN] oedipus_lex 2.6.2 Released
by Ryan Davis 03 Aug '23

03 Aug '23

oedipus_lex version 2.6.2 has been released! * home: <http://github.com/seattlerb/oedipus_lex> * rdoc: <http://docs.seattlerb.org/oedipus_lex> Oedipus Lex is a lexer generator in the same family as Rexical and Rex. Oedipus Lex is my independent lexer fork of Rexical. Rexical was in turn a fork of Rex. We've been unable to contact the author of rex in order to take it over, fix it up, extend it, and relicense it to MIT. So, Oedipus was written clean-room in order to bypass licensing constraints (and because bootstrapping is fun). Oedipus brings a lot of extras to the table and at this point is only historically related to rexical. The syntax has changed enough that any rexical lexer will have to be tweaked to work inside of oedipus. At the very least, you need to add slashes to all your regexps. Oedipus, like rexical, is based primarily on generating code much like you would a hand-written lexer. It is _not_ a table or hash driven lexer. It uses StrScanner within a multi-level case statement. As such, Oedipus matches on the _first_ match, not the longest (like lex and its ilk). This documentation is not meant to bypass any prerequisite knowledge on lexing or parsing. If you'd like to study the subject in further detail, please try [TIN321] or the [LLVM Tutorial] or some other good resource for CS learning. Books... books are good. I like books. Changes: ### 2.6.2 / 2023-08-03 * 1 bug fix: * Removed extra newline when do_parse option is used.
