What if Ruby 4.0 features could be implemented in pure Ruby?
With TruffleRuby, that’s possible: 73% of the core library is written in Ruby itself.
We currently have 10 issues tagged [easy, pure Ruby] waiting for contributors: github.com/truffleruby/truff…

This release addresses several performance issues detected while getting a large Rails app running on TruffleRuby at Shopify. I’ll write up a blog post with more details soon-ish. In the meanwhile, please give it a try. It should run Rails applications quite well.

The main performance improvement is a complete review of all 100 inline caches to ensure they use splitting to keep these inline caches as fast and monomoprhic as possible. You can find more information about splitting and inline caches in this talk: rubykaigi.org/2023/presentat…

FWIW @TruffleRuby is 45 times faster than YJIT on that benchmark and more importantly has the same performance for all 3 variants! gist.github.com/eregon/8e104…

I wrote (somewhat extensively) about the current state of the Ruby language frontend, including Prism, LRama, "universal" parser, and much more.
I hope this post is able to answer all of the questions I keep getting about where everything is heading.

Native extensions are now compiled using the system toolchain and executed natively instead of using GraalVM LLVM (Sulong), which leads to faster startup, faster warmup, better compatibility, smaller distribution and faster installation.

Full support for the Ruby 3.2 & 3.3 syntax, including pattern matching, was made possible by adopting the Prism parser, which is about twice as fast as the old parser! x.com/TruffleRuby/status/175…
17 Feb 2024
TruffleRuby is now using Prism as its Ruby parser! 🚀 This means *all* the Ruby 3.3 syntax is supported, no exception! It is also twice as fast as the previous parser written in Java! And future Ruby syntax will be available very quickly in TruffleRuby. github.com/oracle/trufflerub…
