ipr VS language

I'm not sure about clang or gcc. For VS, u/GabrielDosReis might be able to speak to the .ifc IPR stability/volatility. My wager (deferring to him to correct me) is that the IPR is still changing over time but will stabilize more over time.

Have you had a look at its uses in the IPR interface and implementation? https://github.com/GabrielDosReis/ipr/blob/main/include/ipr/interface

> C++ has virtually zero tooling

CMake, Meson, Waf, Conan, Visual Studio Code, Visual Studio, CLion, Intel VTune, GDB, LLDB, XCode, Artifactory, SonarQube, clang-tidy, clang-format, astyle, Incredibuild...

> Comparing CMake to cargo is like comparing fifth century fireworks to the Space Shuttle

You are wrong here. Cargo serves a set of fixed "this-is-how-to-do-it" thing. In C++ you can build anything. I do not mean it is better, but C++ software already exists and that is the solution that it works better for it. :)

IPR Library

I noticed that I can enable inline-class as an experiment to play with Extension Types. You need to also add sdk: ^3.3.0-0 to your pubspec.yaml.

Current syntax is not all that bad if you are going to do OO and add various helper methods on `Message` and its subclasses, but if you just want to define your data and no behavior / helpers - then it is exceedingly verbose.

Reference

A future version of Dart will probably support macros which should make this all a bit easier to use, similar to how Swift 5.9 works which makes already fantastic use of its new macro capabilities by integrating mobx (or solidjs) like reactivity into SwiftUI by a harmlessly looking @Obervable annotation.

Coming from a Dart context here where that team is also looking at adding Macros to the language. It was really interesting to compare and contrast some of the approaches https://github.com/dart-lang/language/blob/main/working/macr...

Yes, that needs a bit of boilerplate for the constructor declaration and the extra build method, but I personally don't mind and with implicit constructors this will become much easier. Also, you get a performant UI as Flutter knows to not redraw widgets that didn't change.

I know that it would be nice not to use the generator at all, but we have to wait until static metaprogramming is implemented in dart. https://github.com/dart-lang/language/issues/1482

I implemented a prototype version of the algorithm in that paper when exploring exhaustiveness checking for pattern matching in Dart.

I found it pretty easy to understand, but also really easy to get it to generate huge combinatorially large spaces. Some careful memoization and deduplication helped, but even so I never got the performance to a state I considered acceptable.

Instead, I went with Luc Maranget's classic approach and figured out a way to adapt it to a language with subtyping (with a ton of work from Johnni Winther to figure out all of the hard complex cases around generics):

https://github.com/dart-lang/language/blob/main/accepted/fut...

The performance (in the prototype!) was dramatically better. You can always make pattern matching go combinatorial, but I haven't seen any real-world switches get particularly slow with our approach yet, and we have some fairly large tests of matching on tuples of enums.
