This project aim to convert Black report to CodeClimate format that can be ingest by GitLab.

For security concerns, Docker-in-Docker has been disabled in all GitLab runners that I have access/manage. Because the Code Quality template shipped with GitLab instances use CodeClimate CLI that requires a Docker environment, we can't use it and an alternative solution was required to obtain Black errors in our Code Quality reports.

Simply run the following command:

pip install black-gl-code-quality

If you use Poetry, you can add it to your dev-dependencies:

poetry add --group dev black-gl-code-quality

There is two ways to use this tool:

• by piping Black
• by calling black-gl-code-quality (or by it's alias black-gl-cq) directly

Piping with Black requires to forward stderr to stdout. You can use the following command in the .gitlab-ci.yml:

black --check src/ 2>&1 | black-gl-cq > black-code-quality-report.json

Here's an example for a GitLab-CI job:

lint:black:
  stage: test
  script:
    - source .venv/bin/activate
    - black --check src/ 2>&1 | black-gl-cq > black-code-quality-report.json
  artifacts:
    when: always
    reports:
      codequality: black-code-quality-report.json

Calling black-gl-code-quality (or it's alias black-gl-cq) execute Black with the --check argument. It forwards all arguments you pass if you need to configure Black via the CLI.

Specifying source folders is MANDATORY.

Here's an example for a GitLab-CI job:

lint:black:
  stage: test
  script:
    - source .venv/bin/activate
    - black-gl-cq src/ > black-code-quality-report.json
  artifacts:
    when: always
    reports:
      codequality: black-code-quality-report.json

Admit we want to skip string normalization:

lint:black:
  stage: test
  script:
    - source .venv/bin/activate
    - black-gl-cq -S src/ > black-code-quality-report.json
  artifacts:
    when: always
    reports:
      codequality: black-code-quality-report.json

By default, all errors have the severity major. Depending how you consider Black issues important, you can change the severity for all errors returned by the report by using one of the following values with the BLACK_GL_SEVERITY environment variable: info, minor, major, critical, blocker.

Here's an example for a GitLab-CI job:

lint:black:
  stage: test
  variables:
    BLACK_GL_SEVERITY: minor
  script:
    - source .venv/bin/activate
    - black-gl-cq src/ > black-code-quality-report.json
  artifacts:
    when: always
    reports:
      codequality: black-code-quality-report.json

In case you have a suggestion or want a new feature, feel free to open a discussion.

If you found a bug, you can open an issue.

In order to maintain an overall good code quality, this project use the following tools:

• Black
• Isort
• Flake8

Linting and formatting tools are configured to match the current default rules of Black.

Please ensure to run these tools before commiting and submiting a Pull request. In case one of these mentionned tools report an error, the CI will automatically fail.

In case you are able to fix by yourself a bug, enhance the code or implement a new feature, feel free to send a Pull request.
