pylint ignore by directory

Question

Following is from pylint docs:

--ignore=<file>
    Add <file or directory> to the black list. It should be a base name, not a path. You may set this option multiple times. [current: %default]

Yet I'm not having luck getting the directory part work.

I have directory called migrations, which has django-south migration files. As I enter --ignore=migrations it still keeps giving me the errors/warnings in files inside migrations directory.

Could it be that --ignore is not working for directories?

If I could even use regexp to match the ignored files it would work, since django-south files are all named 0001_something, 0002_something...

Since I could not get the ignore by directory to work I have resorted to simply putting # pylint: disable-msg-cat=WCREFI on top of each migration file, which ignores all pylint errors, warnings and infos.

Answer 1

Adding:

[MASTER]
ignore=migrations

To my .pylintrc works with pylint 0.25. My problems are with PyDev which (it seems) is not respecting my settings. This is due, I think, to the fact that it's running pylint per-file, which I think bypasses 'ignore' checks - whether for modules/directories or files. The calls to pylint from PyDev look like:

/path/to/site-packages/pylint/lint.py --include-ids=y /path/to/project/migrations/0018_migration.py

You can not give a path but only the "basename" of the directory. E.g. use --ignore=lib instead of --ignore-=appengine-toolkit/gaetk/lib.

Problem is you will ignore all directories named lib.

Answer 3

Although this is an old question it showed up at the top of the list when we were searching stack overflow so i am posting our solution here in the hopes that it might be useful to someone else.

To ignore subdirectories under a directory tree named 3rdparty, we added the following ignore-patterns entry to the [MASTER] entry in .pylintrc.

# Add files or directories matching the regex patterns to the blacklist. The
# regex matches against base names, not paths.
# Ignore all .py files under the 3rdparty subdirectory.
ignore-patterns=**/3rdparty/**/*.py

This fixed the problem for pylint-1.7.1.

We were originally confused by the "base names" clause in the comments. Apparently it does accept paths with wildcards. At least it did for us. Your mileage may vary.

You can then use Bash expansion to your advantage:

--ignore=migrations/{0000..1000}_something
