Implement Custom Data for Parsers in Tree about gumtree HOT 7 CLOSED

First question: this custom data would need to be serialized in your use case, or just alive during runtime?

from gumtree.

The use case I am considering is this.

1. the user gets some code from an editor (i.e. eclipse)
2. the user then parses the code into a Gumtree AST.
3. the use then does some science and now wants to modify the original code.
4. the user uses the link back to the original tree and is able to modify the original code

I think that this would be ok for have it to be alive just during runtime.

OK I propose that we will implement this feature as a public Object getMetadata(String key) and public void setMetadata(String key, Object obj) that you can use on a ITree. It would do the trick?

Actually it was the purpose of the tree_info branch (before we messed it up).
Jean-Rémy’s proposition is still but subset of what is needed but can be easily implemented.

That seems like a great place to start!

I think the new API for metadata (branch metadata) is close enough of what we were planning.
There are two levels on metadata, globals (on treecontext) and locals (on ITree). Locals may overrides globals.
Metadata can be serialized/unserialized quite easily (with lambda). Generators can provide on tree context serializers.

that sounds great to me.
