[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:444336] [ANN] zenweb 3.11.0 Released

by Ryan Davis

zenweb version 3.11.0 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: ### 3.11.0 / 2023-09-28 * 1 minor enhancement: * Added Page#link_head helper method to clean up <link...> tags

[ruby-talk:444332] [ANN] httpx 0.24.6 released

by Tiago Cardoso

httpx 0.24.6 has been released. NOTE: If nothing significant happens, this will be the last release before v1 is released (which should happen during next week). ``` 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: # 0.24.6 ## Bugfixes * fix Session class assertions not prepared for class overrides, which could break some plugins which override the Session class on load (such as `datadog` or `webmock` adapters). # 0.24.5 ## Bugfixes * fix for SSL handshake post connection SAN check using IPv6 address. * fix bug in DoH impl when the request returned no answer. # 0.24.4 ## Improvements * `digest_authentication` plugin now supports passing HA1hashed with password HA1s (common to store in htdigest files for example) when setting the`:hashed` kwarg to `true` in the `.digest_auth` call. * ex: `http.digest_auth(user, get_hashed_passwd_from_htdigest(user), hashed: true)` * TLS session resumption is now supported * whenever possible, `httpx` sessions will recycle used connections so that, in the case of TLS connections, the first session will keep being reused, thereby diminishing the overhead of subsequent TLS handshakes on the same host. * TLS sessions are only reused in the scope of the same `httpx` session, unless the `:persistent` plugin is used, in which case, the persisted `httpx` session will always try to resume TLS sessions. ## Bugfixes * When explicitly using IP addresses in the URL host, TLS handshake will now verify if the IP address is included in the certificate. * IP address will keep not being used for SNI, as per RFC 6066, section 3. * ex: `http.get("https://10.12.0.12/get")` * if you want the prior behavior, set `HTTPX.with(ssl: {verify_hostname: false})` * Turn TLS hostname verification on for `jruby` (it's turned off by default). * if you want the prior behavior, set `HTTPX.with(ssl: {verify_hostname: false})` # 0.24.3 ## Improvements * faraday adapter: reraise httpx timeout errors as faraday errors. * faraday adapter: support `:bind` option, which expects a host and port to connect to. ## Bugfixes * faraday adapter: fix `#close` implementation using the wrong ivar. * faraday adapter: fix usage of `requestt_timeout` translation of faraday timeouts into httpx timeouts. * faraday adapter: `ssl: { verify: false }` was being ignored, and certification verification was still proceeding. # 0.24.2 ## Improvements * besides an array, `:resolver_options` can now receive a hash for `:nameserver`, which **must** be indexed by IP family (`Socket::AF_INET6` or `Socket::AF_INET`); each group of nameservers will be used for emitting DNS queries of that iP family. * `:authentication` plugin: Added `#bearer_auth` helper, which receives a token, and sets it as `"Bearer $TOKEN` in the `"authorization"` header. * `faraday` adapter: now implements `#build_connection` and `#close`, will now interact with `faraday` native timeouts (`:read`, `:write` and `:connect`). ## Bugfixes * fixed native resolver bug when queries involving intermediate alias would be kept after the original query and mess with re-queries. # 0.24.1 ## Improvements * datadog adapter: support `:service_name` configuration option. * datadog adapter: set `:distributed_tracing` to `true` by default. * `:proxy` plugin: when the proxy uri uses an unsupported scheme (i.e.: "scp://125.24.2.1"), a more user friendly error is raised (instead of the previous broken stacktrace). ## Bugfixes * datadog adapter: fix tracing enable call, which was wrongly calling `super`. + `:proxy` plugin: fix for bug which was turning off plugins overriding `HTTPX::Connection#send` (such as the datadog adapter).

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.
