JRuby VS MRuby

Another way to look at it based on coming across it in enterprise:

How did he build something adopted by so many enterprises?

It does some things at scale very well and has been afforded the performance improvements of very smart people for 30y.

It’s not to say the language isn’t verbose, one of my favourite features was the ability to write code in other languages right inside the a Java app pretty well in-line by using the JVM, thanks to JSR-223.

It was possible to write Ruby or Python code via Jruby or Jython and run it in the JVM.

As someone who has looked at Shoes several times but never dove in, it's confusing how Shoes 4 has been the "preview version" of Shoes for, like, a decade or more. It made me actively avoid getting invested in Shoes 3 (the release promoted on the linked website) because Shoes 4 requires JRuby and I am happy with CRuby (the Ruby interpreter most people think of when they hear "Ruby").

No disrespect to the developers but to me it feels like taking over a GUI toolkit created "to teach programming to everyone" (to quote the Shoes 4 readme) and making it depend upon a super-complicated enterprise-focused Ruby was sort of Missing The Point™ in a huge way.

Heck I couldn't even switch to JRuby if I wanted to because I <3 Ractors and JRuby still lacks CRuby 3.0 feature parity: https://github.com/jruby/jruby/issues/7459

__callee__ now properly returns the name under which a method was called, which will be the new name in the case of aliased methods. #2305, #7702

Issue tracker: https://github.com/jruby/jruby/issues

rdoc has been updated to 6.3.3 to fix all known CVEs. (#7396, #7404)

Altering the visibility of an included module method no longer changes what super method gets called. (#7240, #7343, #7344, #7356)

It looks like the readme is copy pasta from jruby: https://github.com/jruby/jruby

Are you sure about that?

not an exhaustive list but https://github.com/mruby/mruby/issues/3962 has a few examples. some neat uses though

From our experience, the use of that option in a regular web app is uncommon. However, sending emails via Net::SMTP could be a fit if you use mruby (a lightweight implementation of the Ruby language) on some IoT device. Also, it will do if used in serverless computing, for example, AWS Lambda. Check out this script example first and then we’ll go through it in detail.

It's more on the embedded end of the spectrum, but https://github.com/mruby/mruby is another option in compiling ruby code and c extensions down to a single binary.
