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:444360] [ANN] httpx 1.1.0 released
by Tiago Cardoso 31 Oct '23

31 Oct '23

httpx 1.1.0 has been released. ``` HTTPX.get("https://gitlab.com/honeyryderchuck/httpx <https://gitlab.com/honeyryderchuck/httpx>") ``` HTTPX is an HTTP client library for the Ruby programming language. Among its features, it supports: * HTTP/2 and HTTP/1.x protocol versions * Concurrent requests by default * Simple and chainable API * Proxy Support (HTTP(S), CONNECT tunnel, Socks4/4a/5) * Simple Timeout System * Lightweight by default (require what you need) And also: * Compression (gzip, deflate, brotli) * Streaming Requests * Authentication (Basic Auth, Digest Auth, AWS Sigv4) * Expect 100-continue * Multipart Requests * Cookies * HTTP/2 Server Push * H2C Upgrade * Automatic follow redirects * International Domain Names * GRPC * Circuit breaker * WebDAV * Datadog integration * Faraday integration * Webmock integration * Sentry integration Here are the updates since the last release: # 1.1.0 ## Features A function, `#peer_address`, was added to the response object, which returns the IP (either a string or an `IPAddr` object) from the socket used to get the response from. ```ruby response = HTTPX.get("https://example.com") response.peer_address #=> #<IPAddr: IPv4:93.184.216.34/255.255.255.255> ``` error responses will also expose an IP address via `#peer_address` as long a connection happened before the error. ## Improvements * A performance regression involving the new default timeouts has been fixed, which could cause significant overhead in "multiple requests in sequence" scenarios, and was clearly visible in benchmarks. * this regression will still be seen in jruby due to a bug, which fix will be released in jruby 9.4.5.0. * HTTP/1.1 connections are now set to handle as many requests as they can by default (instead of the past default of max 200, at which point they'd be recycled). * tolerate the inexistence of `openssl` in the installed ruby, like `net-http` does. * `on_connection_opened` and `on_connection_closed` will yield the `OpenSSL::SSL::SSLSocket` instance for `https` backed origins (instead of always the `Socket` instance). ## Bugfixes * when using the `:native` resolver (default option), a default of 1 for ndots is set, for systems which do not set one. * replaced usage of `Float::INFINITY` with `nil` for timeout defaults, as the former can't be used in IO wait functions. * `faraday` adapter timeout setup now maps to `:read_timeout` and `:write_timeout` options from `httpx`. * fixed HTTP/1.1 connection recycling on number of max requests exhausted. * `response.json` will now work when "content-type" header is set to "application/hal+json". ## Chore * when using the `:cookies` plugin, a warning message to install the idnx message will only be emitted if the cookie domain is an IDN (this message was being shown all the time since v1 release). # 1.0.2 ## bugfixes * bump `http-2-next` to 1.0.1, which fixes a bug where http/2 connection interprets MAX_CONCURRENT_STREAMS as request cap. * `grpc`: setup of rpc calls from camel-cased symbols has been fixed. As an improvement, the GRPC-enabled session will now support both snake-cased, as well as camel-cased calls. * `datadog` adapter has now been patched to support the most recent breaking changes of `ddtrace` configuration DSL (`env_to_bool` is no longer supported). # 1.0.1 ## Bugfixes * do not try to inflate empty chunks (it triggered an error during response decoding).

[ruby-talk:444361] Weird Rails behaviour when dockerised
by Peter Hickman 30 Oct '23

30 Oct '23

I have this old app, Ruby 1.8.7, Rails 2.3.2, that runs on Ubuntu 1404. It is old, rock solid and undocumented. We are going to rewrite it but at present we have dockerised it as is because we feared that the host that runs it (also very old) may simply die So we build a container around 14.04, compiled ruby 1.8.7 and installed the necessary gems. Fired it up and pointed the load balancer at it. It is working just fine and we can finally breath. To be clear the container only contains the Rails app and the unicorn_rails application server, the rest of the stack, Nginx and the database, live in their own 22.04 containers Now the odd part, despite the application running in production mode it logs like it is in development mode and the logs are bloated with all the database activity. The log files are a minimum 2/3 database logging. The old installation doesn't do this For the life of me I can not work out how to stop the database logging Any ideas?

[ruby-talk:444357] Glimmer DSL for LibUI Custom Shapes
by Andy Maleh 27 Oct '23

27 Oct '23

Glimmer DSL for LibUI 0.10.1 & 0.10.0 ship with support for building and scaffolding Area Canvas Graphics Custom Shapes (with optional Gemification). Custom shapes represent higher-order graphical concepts, like `cube`, `cylinder`, and `uml_class`, that could be formed out of more rudimentary shapes like `rectangle`, `circle`, `bezier`, and `text`, to aggregate and simplify interaction with them as coarse-grained components in a desktop application. Custom Shapes improve productivity significantly through code reuse in graphical desktop applications that rely on Area Canvas Graphics, like UML Diagramming tools, Traffic Control Signalling apps, and games. https://raw.githubusercontent.com/AndyObtiva/glimmer-dsl-libui/master/image… Learn more at this blog post: https://andymaleh.blogspot.com/2023/10/glimmer-dsl-for-libui-custom-shapes.… GitHub Repo: https://github.com/AndyObtiva/glimmer-dsl-libui RubyGem: https://rubygems.org/gems/glimmer-dsl-libui

[ruby-talk:444349] [ANN] wxRuby3 0.9.0 stable release
by martin＠corino.nl 15 Oct '23

15 Oct '23

It took a little longer than I had hoped but here it is. After almost a year of development the very first stable release of wxRuby3 has been released. wxRuby3 is a cross-platform GUI library for Ruby, based on the mature wxWidgets GUI toolkit for C++. It uses native widgets wherever possible, providing the correct look, feel and behavior to GUI applications on Windows, OS X and Linux/GTK. wxRuby aims to provide a comprehensive solution to developing professional-standard desktop applications in Ruby. This release includes - the last stabilization improvements and error corrections; - improved and extended documentation; - additional functionality incl. full support for the RichTextCtrl library (see the new, extended, RichText sample). Why a 0.9.0 version for the first stable release? Why not 1.0.0? Although I am quite certain about it's stability I am equally certain there may be things I overlooked or missed out on. Also I am convinced that, now that most wrinkles have become clear and straightened out and I can take a breather from tracking them down, I can improve and enhance the implementation if I take a little time. Apart from that the available samples for a large part are still straight ports from the 'old' wxRuby(2) libraries and could use some TLC to make them more substantial and more 'wxRuby3'. So, what's next? The coming time will be used working up to a 1.0.0 stable release with improvements in the implementation which (hopefully) will give us performance and (even more) stability enhancements and footprint reduction. Equally important will be improving and extending the documentation , the available samples and regression tests.
