Re: [Python-ideas] Non-intrusive debug logging

I think part of the reason that logging appears complicated is because logging actually is complicated. In the myriad different contexts a Python program runs (daemon, command line tool, interactively), the logging output should be going to all sorts of different places. Thus was born handlers. If

Re: [Python-ideas] Non-intrusive debug logging

This can be accomplished as a decorator. Jim Crist wrote a version of this using the codetransformer library. The usage is pretty simple: @trace() def sum_word_lengths(words): total = 0 for w in words: word_length = len(w) total += word_length return total >>>

Re: [Python-ideas] Non-intrusive debug logging

This strikes me as something a debugger should do, rather than the regular interpreter. And using comment-based syntax means that they would get ignored by the regular interpreter— which is exactly what you want. As for a decoration approach— that wouldn’t let you do anything on a line by line

Re: [Python-ideas] Non-intrusive debug logging

Some thoughts: 1. I too dislikes the idea of using comments as semantically significant annotations. I think it's quite OK for annotation that are aimed at external tools (e.g. '# nocover' or '# noqa') but not for runtime behavior. 2. It's probably possible do do interesting things using

[Python-ideas] Non-intrusive debug logging

Everyone uses logging during code development to help in debugging. Whether using a logging module or plain old print statements, this usually requires introducing one or (many) more lines of code into the model being worked on, making the existing, functional code more difficult to read. It
