@andrewstein it appears that simpleName is long dead code which was only added for SexpMaker (which no longer calls it). It is isolated enough that I will remove this method for JRuby 10 (we generally do not consider org.jruby.ast to be a public API space -- although if you have a need then let me know).

Thank you @enebo for your reply.

My goal is to dump the AST out to a file. I cannot use the Node.toString(true, 0) for this since it is very incomplete. For example, for a StrNode it does not show the actual string. So I am rolling out my own. (If there is something already available I am not aware of it. I am aware of the ruby_parser gem and would be happy to use a Java equivalent if available.)

Node.toString(true, 0) uses a method node.getNodeName() which is protected, so I chose node.getNodeType().simpleName() instead. I guess I can roll my own equivalent of node.getNodeName() which is a simple mangling of the class name.

@andrewstein This may not help you since you are probably using Java only but we have bin/ast which does print out the AST but it is a mixture or Ruby and Java. It also probably does not print what you are looking for (it is largely something for us to see structure). You can look with jruby -S ast -e foo. It might be helpful for you to figure out how to do this using Java though.

I will also point out JRuby 10 will work with both the legacy parser (which you are looking at) and the prism parser (a cross-Ruby-implementation) which effectively is a foreign function callout to a C library which produces a blob we can turn into an AST. The AST it makes is not the same as the legacy one. That parser is fairly well documented though and it can also do syntax-level AST info. We do have some experimental bindings to call it through Chicory using web assembly so there is a pure-Java path...just not completed yet.

That is a lot of digest but I am not sure how long and for what you need this .

@andrewstein you can pop onto our matrix channel to chat too if you want: https://app.element.io/?updated=1.11.69#/room/#jruby:matrix.org

Thank you @enebo I will have to look into all of this in two weeks time. Happy holidays :-)
