3 # This GitHub workflow automates submitting builds to Coverity Scan. To enable it,
4 # set the repository variable `ENABLE_COVERITY_SCAN_FOR_BRANCHES` (for details, see
5 # https://docs.github.com/en/actions/learn-github-actions/variables) to a JSON
6 # string array containing the names of the branches for which the workflow should be
7 # run, e.g. `["main", "next"]`.
8 #
9 # In addition, two repository secrets must be set (for details how to add secrets, see
10 # https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions):
11 # `COVERITY_SCAN_EMAIL` and `COVERITY_SCAN_TOKEN`. The former specifies the
12 # email to which the Coverity reports should be sent and the latter can be
13 # obtained from the Project Settings tab of the Coverity project).
14 #
15 # The workflow runs on `ubuntu-latest` by default. This can be overridden by setting
16 # the repository variable `ENABLE_COVERITY_SCAN_ON_OS` to a JSON string array specifying
17 # the operating systems, e.g. `["ubuntu-latest", "windows-latest"]`.
18 #
19 # By default, the builds are submitted to the Coverity project `git`. To override this,
20 # set the repository variable `COVERITY_PROJECT`.
