allow per-file skip_list or whole-file noqa

[eengstrom]

In a couple of places I've wanted to be able to exclude some lint rules from applying to an entire file.
e.g. name[play] where the entire playbook consists of nothing but - import_playbook: some-playbook.yml.
I have looked at the documentation and found no such feature.

rudimentary ideas I've come up with so far:

allowing skip_list[_by_path]

e.g. in .ansbile-lint

skip_list_by_path:
  aggregator.yml:
    - name[play]

in-file noqa[-file] block

e.g. at or near the top of a file:

# Ignore these ansible-lint rules for the entire file:
# noqa: name[play]
# or 
# noqa-file: name[play]

This can be achieved with: docs/lint/configuring/#ignoring-rules-for-entire-files

(but note #3068).

While I agree that what you suggest partially solves the problem I outline, I have several issues with that approach:

First, if used as a .ansible-lint-ignore, as opposed to a .config/ansible-lint-ignore.txt, it only works on filenames in the current directory, but not path names. e.g.:

playbook.yml name[play]

works ... but this does not work:

path/to/playbook.yml name[play]

That means you need to have directory specific versions, unlike say .gitignore. Plausible workaround - use symlinks to a single copy, I guess.

Second, when the Ansible Lint docs say "ignore", the lint rules defined like those don't really "ignore" that check. Instead, it is marked as a WARNING, not an ERROR. The upshot of that is that the ignore-d rule is still in the output, and then downstream tools, such as VSCode, still pick up on it and present it as a problem. That's not really "ignored". This is, as you mentioned, already discussed here:

#3068

Third, this feature require each file to be enumerated.

IMO, it would be way nicer if ansible-lint followed the yamllint config idea:
