Is it possible to extract external lut file information from the Python API?

I am working on a scene parser in Houdini and I know I can use the OCIO environment variable to grab the config file, but some users are using external LUT files in their pipeline as well and I am not sure how to reliably detect the LUT files. I can always just parse the config file, but I would really rather not do that.

Ideally, a feature request for a Config object member function which returns a list of the paths to all files associated with the config would be AMAZING, but I would settle for just any way to retrieve the LUT files from within the API.

OCIO accesses the LUTs referenced by the config file using the search_path and any context variables that have been defined. The determination of the actual resolved path is fairly complex. There should be no need for an application to extract the path and building anything that requires that path might be quite fragile.

@doug-walker Thank you for the reply. Sounds like it would be reasonable to make an actual feature request then, as hardening something like that so it does not break on updates would be valuable for maintaining the algorithms I am working on. The LUT files are required for accurate rendering, so it is vital that they are properly discovered in the process.

I am pretty sure you have given me enough for now though. I am leaving this open for the moment so I can come back to it if my hypothesis is incorrect today while working on the problem.
