Does OmegaConf keep information about the ordered map of the raw configuration?

[noklam]

Pseudocode:

from omegaconf import OmegaConf

conf = OmegaConf.load("xxxx.yml")
conf.lc

>>> line: 10, col: 5

For example, this is supported with yaml https://yaml.readthedocs.io/en/latest/detail/. Obviously it won't work for the Python API. I wonder how could this be supported or could I extend OmegaConf myself. Does OmegaConf preserve the tree during resolution? It would be super useful for me as I am trying to build some sort of LSP IDE feature on top of it so navigation/go to definition would be easier.

I know for DictConfig there is a _parent attribute, is there a way that I can extend the config resolution method so that these metadata can be kept.

I think you could extend the DictConfig and ListConfig constructors so that when you create the config in

omegaconf/omegaconf/omegaconf.py

Line 832 in ed96010

def _create_impl( # noqa F811

you can pass this information when available, which could then be stored in the metadata (you'd also have to add this to the ContainerMetadata class).
