Issue #14844 has been updated by ioquatix (Samuel Williams).


It would be nice to expose the method/function name if possible. In the case of code coverage, it would allow user to explicitly ignore functions, because we can traverse the AST and ignore every line of the function.

Feature #14844: Future of RubyVM::AST?

Hi! Thanks for all your great work on the Ruby language. 

I saw the new RubyVM::AST module in 2.6.0-preview2 and I quickly went to try it out. 

I'd love to have a well-documented, user-friendly way to parse and manipulate Ruby code using the Ruby standard library, so I'm pretty excited to try it out. (I've been trying to learn Ripper recently, too: https://ripper-preview.herokuapp.com/, https://rmosolgo.github.io/ripper_events/ .)

Based on my exploration, I opened a small PR on GitHub with some documentation: https://github.com/ruby/ruby/pull/1888

I'm curious though, are there future plans for this module? For example, we might: 

- Add more details about each node (for example, we could expose the names of identifiers and operators through the node classes)
- Document each node type 

I see there is a lot more information in the C structures that we could expose, and I'm interested to help out if it's valuable. What do you think?
