%%%I recently wanted to do batch conversion of Collada files to .blend files. However, the existing bpy.ops.wm.collada_import operator is unusable from batch mode: it fails with “RuntimeError: Operator bpy.ops.wm.collada_import.poll() failed, context is incorrect” when you try invoking it from a script.

Therefore, I came up with the enclosed patch, which adds a bpy.utils.collada_import routine that doesn’t try to do any UI of its own, it just imports the file specified.

I had to make some minor changes to the definitions of the args passed to the collada_import/export routines, because I couldn’t figure out where the “Scene” typedef was defined, so I just used “struct Scene” instead.%%%

I think operator itself could be changed in a way to be usable for the batch import/export by just using some default values for whatever setting it expects to be pulled form the context. Or, alternatively, if they're really crucial for operator thy can be properties initialzied form context on operator invoke().

The issue with your approach is that it adds rather specific function to rather generic module.

No activity in quite some time now and current state of the patch can not be accepted. But if it is changed to use operator properties instead it'll be all fine.
