A swarm docker stack deploy env-file value must be a single physical line; the multi-line GITLAB_OMNIBUS_CONFIG was read as separate whitespace-named env entries and aborted the deploy. Add a depth-aware ruby_single_line filter that collapses the Ruby program to one line (statement-boundary newlines at bracket depth 0 become ';', newlines inside an open bracket or a string become a space so hash/array literals like the OIDC omniauth_providers stay valid) and apply it on the swarm branch only; compose keeps the multi-line value unchanged. Covered by tests/unit/plugins/filter/test_ruby.py (10 cases incl. a realistic omnibus config, escaped quotes and nested literals). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
