Future of Ruby – AST Tooling
There are already some techniques capable of doing just this, by combining Parser with Unparser, but of course such things can only be done on Ruby files read in rather than in a REPL session which is where a lot more fun could happen.

How to write a compiler or interpreter in rust
In terms of parsing style I suggest sticking with a hand-written recursive-descent parser. Parser generators seem appealing at first, but I always ran into annoying limitations when using them (I wrote one in Ruby myself as well, and used this for this project). Parsing combinators are useful for small inputs, but I find them difficult to use for anything but simple cases.
What are some alternatives?
When comparing unparser and Oga you can also consider the following projects:
anystyle - Fast citation reference parsing
Nokogiri - Nokogiri (鋸) makes it easy and painless to work with XML and HTML from Ruby.
