I think this is caused by we do not handle attrpath in ASTs, but playing with random strings checking \n, this is just a workaround for poor parser.

https://github.com/nix-community/nixd/blob/2611b45cf786e7ba1679cd4adfe256ca85b371f5/nixd/lib/Server/Controller.cpp#L605C9-L617C10

Currently the frontend (parser) does not support attrpath at all. We recently merged libnixf as the new parser, but it is currently not working with the Controller. The controller utilizes a parser cherry-picked from NixOS/nix repo, which does not allow us find attrpaths correctly.

Contributions are welcomed if you would like to do such thing, or just offload some of my work.

[inclyc]

This should be addressed by the new frontend https://github.com/nix-community/nixd/tree/main/libnixf the merging work is still on-going. We currently blocked by in-complete semantic analysis module, and serialization algorithms.

[inclyc]

In #415 attrpath is retrieved from AST. So this should be fixed.
