[ruby-talk:444119] Drum Solo Demo of Glimmer Metronome (+ Menus & Shortcuts)
by Andy Maleh 02 Feb '23

02 Feb '23

I recorded a drum solo to demo Glimmer Metronome, a Ruby-based metronome GUI app that supports different beat counts, click sounds, and tempos, including tap-based tempo calculation. It was built with Glimmer DSL for SWT using JRuby to help me with my drumming practice. Glimmer Metronome just received a new update in version 1.1.4 that adds menus and keyboard shortcuts, thus becoming more user-friendly when using via the keyboard alone. https://youtube.com/shorts/F4xu13y0wTM https://andymaleh.blogspot.com/2023/02/drum-solo-demo-of-glimmer-metronome.…

[ruby-talk:444116] [ANN] RubyInline 3.13.0 Released
by Ryan Davis 01 Feb '23

01 Feb '23

RubyInline version 3.13.0 has been released! * rdoc: <http://docs.seattlerb.org/RubyInline/> * home: <http://www.zenspider.com/ZSS/Products/RubyInline/> * code: <https://github.com/seattlerb/rubyinline> Inline allows you to write foreign code within your ruby code. It automatically determines if the code in question has changed and builds it only when necessary. The extensions are then automatically loaded into the class/module that defines it. You can even write extra builders that will allow you to write inlined code in any language. Use Inline::C as a template and look at Module#inline for the required API. Changes: ### 3.13.0 / 2023-01-31 * 1 minor enhancement: * Error out if current ruby isn't configured for ENABLE_SHARED. * 1 bug fix: * Clean up examples. C++ warns about ANYARGS deprecation. Gonna have to sit with it for now.

[ruby-talk:444115] Glimmer Ecosystem, Glimte 3rd Party Framework, PasswordStore
by Andy Maleh 28 Jan '23

28 Jan '23

Traditionally, Glimmer GUI gems have been mostly a one-sided effort. Well, that changes with Glimte! Glimte is a 3rd party framework built on top of Glimmer (Tk flavor) by Phaengris to facilitate following a certain flavor of the MVC pattern (Model-View-Controller) called MVVM (Model-View-ViewModel). It encourages a model of programming for desktop GUI views that is similar to Rails .erb https://andymaleh.blogspot.com/2023/01/glimmer-ecosystem-glimte-passwordsto…

[ruby-talk:444105] Ractor status: are they used?
by Lionel Bouton 24 Jan '23

24 Jan '23

Hi, I just evaluated the possibility of using Ractors to distribute processing using various gems with native extensions (some matrix/vector computations with Numo::Linalg and approximate vector searches) and I've mixed feelings. The Ractor design seems very sound to me and I would prefer to use them to distribute the load on multiple CPUs but in practice I see 2 major obstacles : - the first use of Ractor code isn't encouraging, even with Ruby 3.2.0, as it outputs : "warning: Ractor is experimental, and the behavior may change in future versions of Ruby! Also there are many implementation issues." - when heavy computations are involved you are probably already using gems with native extensions and when trying to use them in a non-main Ractor you will almost always get an exception : "ractor unsafe method called from not main ractor (Ractor::UnsafeError)" This last problem could be manageable, according to : https://bugs.ruby-lang.org/issues/17307 native extensions should mark their individual functions as thread safe using : #ifdef HAVE_RB_EXT_RACTOR_SAFE rb_ext_ractor_safe(true); #endif I was considering contacting the maintainers of the various gems that we use to check with them which methods are safe and to see if I can submit a pull request but I'm a bit hesitant and wonders if Ractors are actually used and stable enough for maintainers to care. Do people on this list use Ractors? What for? Do people code gems with native extensions with them in mind? I've seen traces of rb_ext_ractor_safe when searching on Github but almost all of the matches are from load.h from the Ruby headers but not many actual uses (in the 4 first pages of results Psych and TruffleRuby are the only exceptions and the first external gem is ruby-extlz4 on the 5th page...). I've yet to see how the ffi gem can handle Ractors, I already know there's no trace of Ractors in its code and this could be a complete new can of worms (or not...). I'll dig a bit more but in my current position I think I'll favor a multi-process solution to scale (mostly because I don't have a definitive list of gems I'll have to patch at this point and time is short). That's a shame and I'm willing to revisit this later. Best regards, Lionel

[ruby-talk:444104] [ANN] cel 0.2.0 released
by Tiago Cardoso 17 Jan '23

17 Jan '23

cel 0.2.0 has been released. https://gitlab.com/honeyryderchuck/cel-ruby Pure Ruby implementation of Google Common Expression Language, https://opensource.google/projects/cel. > The Common Expression Language (CEL) implements common semantics for expression evaluation, enabling different applications to more easily interoperate. ``` env = Cel::Environment.new(name: :string, group: :string) ast = env.compile('name.startsWith("/groups/" + group)') prg = env.program(ast) return_value = prg.evaluate(name: Cel::String.new("/groups/ acme.co/documents/secret-stuff"), group: Cel::String.new("acme.co"))) puts return_value #=> true ``` These are the announcements since the last release: ## [0.2.0] - 2023-01-17 ### Features #### Timestamp/Duration types Implementing `Cel::Timestamp` and `Cel::Duration` CEL types, along with support for functions for those types (such as `getDate`, `getDayOfYear`). ```ruby Cel::Environment.new.evaluate("timestamp('2022-12-25T00:00:00Z').getDate()") #=> 25 Cel::Environment.new.evaluate("duration('3600s10ms').getHours()") #=> 1 ``` #### Protobuf-to-CEL conversion Support for auto-conversion of certain protobuf messages in the `google.protobf` package to CEL types. https://github.com/google/cel-spec/blob/master/doc/langdef.md#dynamic-values ```ruby Cel::Environment.new.evaluate("google.protobuf.BoolValue{value: true}") #=> true Cel::Environment.new.evaluate("google.protobuf.Value{string_value: 'bla'}") #=> "bla" ``` #### Custom Functions `cel` supports the definition of custom functions in the environment, to be used in expressions: ```ruby Cel::Environment.new(foo: Cel::Function(:int, :int, return_type: :int) { |a, b| a + b }).evaluate("foo(2, 2)") #=> 4 ``` ### Expression encoding/decoding Expressions can now be encoded and decoded, to improve storage / reparsing to and from JSON, for example. ```ruby enc = Cel::Environment.new.encode("1 == 2") #=> ["op", ... store_to_db(JSON.dump(enc)) # then, somewhere else env = Cel::Environment.new ast = env.decode(JSON.parse(read_from_db)) env.evaluate(ast) #=> 3 ``` **NOTE**: This feature is only available in ruby 3.1 . ### Bugfixes * fixed parser bug disallowing identifiers composed "true" or "false" (such as "true_name"). ## [0.1.2] - 2022-11-10 point release to update links in rubygems. ## [0.1.1] - 2022-08-11 * fixed handling of comparison of primmitive types with Cel types. * fixed truffleruby compatibility by improving parser number handling.
