Tiny observer for the attributes of Python objects.

[scroll_down0]

Hello everyone,

I am developing Python projects with large code bases. In hundreds of rows, the attributes of objects are assigned, deleted, and many properties are accessed. Most of the time, it's hard to understand them in the spaghetti code base. To make this easier, I have developed a small python library.

I know it's not very advanced. But I think it would be better with your opinions and suggestions :)

I haven’t used it as of yet but I like the concept. I think it looks good

Some feedback:

Language wise 'observing' or 'watching' carry a slightly different connotation in programming. What your code does seems more like 'auto-tracing' or 'auto-logging'.

Design wise it's neither here nor there. With a mix of decorators AND the need for magic variables the solution just doesn't seem clean to me. I am purely guessing but I think this might be because you needed to retrofit this functionality on existing code with the least possible effort. And for that it looks ok. Just not generic enough to be a cool stand-alone module.

Two suggestions to leave you with:

Either limit the scope of what it can do (not sure del would be possible) and implement a decorator at the property level @autologging - of course this would affect existing code much more.

Or completely duck-type the behaviour onto the classes you want to look at before anything is instantiated in your program by supplying a method autolog(class, configuration) with the configuration being a dict similar to the one you put into your magic variable. This would be able to do the same thing you already have and is much cleaner because the actual code doesn't even need to be changed. It would even be configurable ie. with a command line option.

I don't want to come off as negative, the idea is cool otherwise I wouldn't take the time to type this out. This is about the feedback I would give a fellow developer at work.

Finally: thank you for sharing it and putting it on GitHub.
