| # This GitHub workflow automates submitting builds to Coverity Scan. To enable it, | |
| # set the repository variable `ENABLE_COVERITY_SCAN_FOR_BRANCHES` (for details, see | |
| # https://docs.github.com/en/actions/learn-github-actions/variables) to a JSON | |
| # string array containing the names of the branches for which the workflow should be | |
| # run, e.g. `["main", "next"]`. | |
| # | |
| # In addition, two repository secrets must be set (for details how to add secrets, see | |
| # https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions): | |
| # `COVERITY_SCAN_EMAIL` and `COVERITY_SCAN_TOKEN`. The former specifies the | |
| # email to which the Coverity reports should be sent and the latter can be | |
| # obtained from the Project Settings tab of the Coverity project). | |
| # | |
| # The workflow runs on `ubuntu-latest` by default. This can be overridden by setting | |
| # the repository variable `ENABLE_COVERITY_SCAN_ON_OS` to a JSON string array specifying | |
| # the operating systems, e.g. `["ubuntu-latest", "windows-latest"]`. | |
| # | |
| # By default, the builds are submitted to the Coverity project `git`. To override this, | |
| # set the repository variable `COVERITY_PROJECT`. | |
