Parses the JSON OperationOutcome bundle produced by the Java FHIR Validator, emits GitHub check annotations (❌, ⚠️, ℹ️) for issues at or above the configured severity, supports optional filtering out known issues by specifying combinations of filename, messageId, details (with wildcard), and location, and generates a summary Markdown table with issue counts and columns (File, Severity, Details, Location, Code, MessageId) in the GitHub Checks UI.

steps:
  - uses: actions/checkout@v3
  - uses: patrick-werner/validation-outcome-markdown-renderer@v1
    with:
      bundle-file: validation.json    # Path to your OperationOutcome JSON file
      include: errors                 # errors, warnings, or all
      filters: |                      # optional: line-separated filters to skip known issues
        # full-line comments beginning with "#" are ignored
        Observation-Linksatrialer-Druck.json|VALIDATION_VAL_PROFILE_MINIMUM|*magic LOINC code*|Observation.code
        # you can also omit fields by leaving them empty between pipes
        |UNKNOWN_CODESYSTEM||Observation.component  # messageId + location only

Each non-empty line represents one skip-rule in the form:

filename | messageId | detailsWildcard | location

Rules

• Fields are separated by | and trimmed.
• Leave a field empty to ignore it (i.e., match anything for that position).
• detailsWildcard and location support * as a wildcard (case-insensitive).
• filename and messageId are matched exactly (case-insensitive for messageId).
• Lines and inline fragments starting with # are treated as comments and ignored.

Examples

# Skip a specific messageId with a details pattern in a single file and location
Observation-Linksatrialer-Druck.json | VALIDATION_VAL_PROFILE_MINIMUM | *magic LOINC code* | Observation.code

# Skip any UNKNOWN_CODESYSTEM at a given location regardless of file/details
| UNKNOWN_CODESYSTEM | | Observation.component

Skip all "magic LOINC code" errors in a specific file:

- uses: patrick-werner/validation-outcome-markdown-renderer@v1
  with:
    bundle-file: validation.json
    include: errors
    filters: |
      Observation-Linksatrialer-Druck.json|VALIDATION_VAL_PROFILE_MINIMUM|*magic LOINC code*|Observation.code

- uses: patrick-werner/validation-outcome-markdown-renderer@v1
  with:
    bundle-file: validation.json
    include: warnings
    filters: |
      # skip known Java‐validator bugs:
      Observation-Linksatrialer-Druck.json|VALIDATION_VAL_PROFILE_MINIMUM|*magic LOINC code*|Observation.code
      Observation-Rechtsatrialer-Druck.json|VALIDATION_VAL_PROFILE_MINIMUM_MAGIC|*magic LOINC code*|Observation.code
      # skip any UNKNOWN_CODESYSTEM warnings in any file/location:
      |UNKNOWN_CODESYSTEM||Observation.component

• Annotations in the console via core.error(), core.warning(), core.info().

• Filter diagnostics: any defined filters that never matched are listed in the logs and in the summary (under “Unused filters”) to highlight stale rules.

• Summary in the Checks tab:

• Exit code

  • Fails if any ERROR remains after filtering.
  • Otherwise succeeds.
