Allowing users to specify objects . object attributes not direclty in the source

[shimwell]

When specifying the object to :select: there is a check to see if this object is the source.keys()

If the object is not in the source keys then an error is raised.

In my case I have wrapped the CadQuery object with another object.

My cadquery object is not directly in the source so it is not found

For my use case it would be better if that RaiseError was swapped to a Warning as and I would be able to enter :select: my_reactor.solid

For example here I have to do cadquery_object = my_reactor.solid and then set :select: cadquery_object

Ideally I would not include the cadquery_object = my_reactor.solid line in the example.

I admit this is quite a niche use case but something for consideration

Yeah, we should probably check recursively for keys (i.e.: select.split(".") would give ["my_reactor", "solid"] and my_reactor should be in source.keys() and solid in my_reactor). Maybe there is a better (more direct) way to do this with Python than a for loop...

I'm in for allowing :select: my_reactor.solid (with the dot). 😊

I shall give eval(source) a try locally it should handle strings that have a variable or a variable with attribute.

It also returns an error if the variable / variable attribute combo is not found
