It should be possible to get a list of possible errors

[Nurdok]

I tried to use the script version from the "rewrite" branch. It seemed that the error numbers were changed and are not longer in sync with the README. This is expected, but there should be a way to ask the tool to describe all the possible errors.
A possible interface would be:

$ pep257 --error-list

D100: Module is missing docstring.
D101: Class is missing docstring.
...

Where if --explain is specified as well, the longer description is printed.

Why would you need that!?

Here's an actual use case - I want to use pep257.py as a mandatory part of our build system at work. However, we don't agree with all the rules of PEP257, so we would like to ignore some of the errors. It should be possible to get a list of them to go through, rather than just wait for an unwanted error to pop up and then dismiss it.

Fair enough. I just ran the code on my code base and decide from that start what to filter.

In an ideal world no filter would be require... see pep8 and pyflakes.

Unfortunately, pep257 has some ugly false positives.

Good luck

I'm closing this as the documentation now lists all possible error codes.
