ansible-lint not triggered during pre-commit hook in Trunk CLI

[howmuch515]

Hi Trunk team,

I'm encountering an issue where ansible-lint does not run during the pre-commit hook, even though it works correctly when running trunk check manually.

Setup

• Trunk CLI version: 1.22.12

• trunk.yaml configuration:

  version: 0.1
  cli:
    version: 1.22.12
  plugins:
    sources:
      - id: trunk
        ref: v1.6.8
        uri: https://github.com/trunk-io/plugins
  lint:
    enabled:
      - markdownlint@0.44.0
      - ansible-lint@25.2.1
    triggers:
      - linters:
          - ansible-lint
        paths:
          - ansible
        targets:
          - ansible
  actions:
    disabled:
      - trunk-announce
      - trunk-check-pre-push
      - trunk-fmt-pre-commit
    enabled:
      - trunk-upgrade-available
      - trunk-check-pre-commit
  runtimes:
    enabled:
      - node@18.20.5
      - python@3.10.8

Steps to Reproduce

1. Set up git hooks:

   trunk git-hooks sync

2. Introduce a deliberate linting issue by using a short module name:

   - name: Ensure ~/.config directory exists
     file:
       path: "{{ ansible_env.HOME }}/.config/"
       state: directory
       mode: "0755"

3. Run trunk check manually:

   trunk check

   Output:

   ansible/roles/set_config/tasks/main.yml:10:3
     Use `ansible.builtin.file` or `ansible.legacy.file` instead.
   ✖ 1 new lint issue
   

4. Commit the changes:

   git commit -am "test"

   Output:

   Checked 1 modified file
   ✔ No issues
   

Observations

• The manual trunk check correctly identifies the linting issue.

• The pre-commit hook does not detect the same issue.

• The pre-commit hook runs the following command:

  trunk check -n -t "git-commit" --index-file '${env.GIT_INDEX_FILE}' --upstream=HEAD

• Running this command manually also fails to detect the issue:

  trunk check -n -t "git-commit" --index-file .git/index --upstream=HEAD

• Omitting the --index-file flag allows the issue to be detected:

  trunk check -n -t "git-commit" --upstream=HEAD

Conclusion

It appears that specifying the --index-file flag causes ansible-lint to skip linting certain files during the pre-commit hook.
Is there a recommended way to ensure ansible-lint runs correctly during pre-commit checks?

Any insights or suggestions would be greatly appreciated.
