| # This step is meant to inline the jobs.if of the next step "library_generation" as | |
| # an env var to avoid injection vulnerabilities. | |
| # Unfortunately, we can't directly reference `env` in jobs.if | |
| # (see https://github.com/actions/runner/issues/2372) | |
| # The chosen workaround is to declare an intermediate step that will output the env var | |
