Configuration

Configuring Code Annotations is a pretty simple affair. Here is an example showing all options:

source_path: /path/to/be/searched/
report_path: /path/to/write/report/to/
safelist_path: .annotation_safe_list.yml
coverage_target: 100.0
annotations:
    ".. annotation_token:":
    ".. annotation_token2:":
    ".. choice_annotation:":
        choices: [choice_1, choice_2, choice_3]
    name_of_annotation_group:
        - ".. first_group_token:":
        - ".. second_group_token:":
            choices: [choice_4, choice_5]
        - ".. third_group_token:":
            choices: [choice_a, choice_b, choice_c, choice_d]
extensions:
    python:
        - py
        - py3
    javascript:
        - js
source_path

The file or directory to be searched for annotations. If a directory, it will be searched recursively. This can be overridden with the --source_path command line option.

report_path

The directory where the YAML report file will be written. If it does not exist, it will be created.

safelist_path

The path to a safelist, used by the Django Search tool to find annotations in models that are defined outside of the local source tree. See safelist for more information.

coverage_target

A number from 0 - 100 that represents the percentage of Django models in the project that should have annotations. The Django Search tool will fail when run with the --coverage option if the covered percentage is below this number. See django_coverage for more information.

annotations

The definition of annotations to be searched for. There are two types of annotations.

  • Basic, or comment, annotations such as annotation_token and first_group_token above, allow for free-form text following the annotation itself. Note the colon after the annotation token! In configuration this type is a mapping type, mapping to a null value.

    Note: At this time the comment must be all on one line. Multi-line annotation comments are not yet supported.

  • Choice annotations, such as choice_annotation, second_group_token and third_group_token, limit the potential values of the annotation to the ones listed in choices. This can help enforce consistency across the code base and make it easier to find or group specific values of annotations. The key “choices” is a keyword for Code Annotations and must be included in the configuration.

In addition to the two types of annotations, it is also possible to group several annotations together into a fixed structure. In our example name_of_annotation_group is a group consisting of 3 annotations. When grouped, all of the annotations in the group must be present, or linting will fail. The order of the grouping does not matter as long as all of them are found before any other annotations. Only one of each annotation is allowed in a group. See Writing Annotations for more information and examples.

extensions

Code Annotations uses Stevedore extensions to extend the capability of finding new language comments. Language extensions are turned on here. The key is the extension name, as given in the setup.py or setup.cfg of the package that installed the extension. The values are a list of file extensions that, when found, will be passed to the extension for annotation searching. See Extensions for details.
