Generating code based on data from Unity

[slimshader]

Hi,

I have a basic setup up and running but I don't really understand how to approach the problem of generating the code that is based on project data and / or scene date etc, example cases:

1. generating constants based on configured Layers or Tags
2. generating constants based on Mecanim variable names
3. generating code based on current scene object hierarchy
4. generating type-safe accessors for JSON files in the project

at first it would seem that IDataProvder should be used to pre-generate the data for the actual generator but since plugins are implemented as regular class libraries outside of Unity, there is no access to scene / project data.
