For example:

   Python： https://docs.python.org/3/reference/index.html

 I can read about Python’s syntax and “core semantics” in the document.

But Where is Ruby Official Language Reference/Manual?

------
1) https://ruby-doc.org/

When I try to go to: https://ruby-doc.org/

I found:  https://ruby-doc.org/3.2.2

This just explains the Class & API and the SEARCH function is hard to use.
e.g It cannot search __FILE__ thought it on "Keywords" chapter.

2) https://rubyreferences.github.io/rubyref/

I can read some "syntax" on this document. But it is not Ruby Official Books and it is not up to date.

3）https://ruby-doc.org/docs/ruby-doc-bundle/Manual/man-1.4/
I found it with the help of Google.
I cannot find this document link on https://ruby-doc.org/
This document is great and written by the author of Ruby.
It looks like the Ruby Official Manual. But it looks too old which was last modified in 1998.

So, Where is Ruby's Official Language Reference/Manual?  😂
