language plugin
go
`go` is a Syrus plugin gem that bundles Go-generic intelligence into a single `PluginRegistry.register` call. It lives at `plugins/go/` inside the Syrus repository and applies to any Go project — there's no framework-specific split here the way `django` splits out of `python`, since net/http, Gin, Echo, etc. don't share a single web-serving convention.

What it provides
| Extension point | What it does |
|---|---|
:prepare_detector | Detects go.mod at the repo root and contributes go mod download (prepare_priority: 40). Go modules have a single package-manifest signal, unlike javascript/python's multi-lockfile priority lists. |
:review_criteria_provider | Seeds a default adversarial-review checklist item — "Flag swallowed errors (_ = err)" — when go.mod is present (same signal as :prepare_detector). |
What this plugin intentionally does NOT provide
No custom :test_result_parser. gotestsum --junitfile=report.xml ./... output is already parsed by core's JunitXmlParser fallback (app/services/junit_xml_parser.rb) via .syrus.yml's junit_output: — same reasoning as the python plugin's pytest --junitxml= case. No custom .syrus.yml parsing code is needed.
No custom :coverage_analyzer. This is a genuine gap unlike Python: go test -coverprofile=coverage.out produces a bespoke text format with no built-in XML/lcov export, unlike coverage.py's native coverage xml. Convert it to a format a core parser already understands instead of writing new Ruby:
- Cobertura (handled by
CoverageAnalysis::Parsers::Cobertura,
app/services/coverage_analysis/parsers/cobertura.rb): pipe through gocov + gocov-xml:
go test -coverprofile=coverage.out ./...
gocov convert coverage.out | gocov-xml > coverage.xml- lcov: convert with
go test -coverprofile=coverage.out ./...
gcov2lcov -infile=coverage.out -outfile=coverage.lcovWire whichever output you produce into .syrus.yml's coverage.sources[].format (cobertura or lcov) — zero new Ruby code required for either path.
A native Go coverage-profile :coverage_analyzer (parsing coverage.out's own text format directly, dropping the extra converter-tool dependency from target repos) is a reasonable follow-up if operators push back on requiring gocov/gcov2lcov, but is out of scope here.
No :preview_provider — there's no single universal Go web-serving convention at the language level (net/http, Gin, Echo, etc. all differ).
Loading the plugin
The plugin registers itself via a Rails engine after_initialize hook once gem "go", path: "plugins/go" is bundled — no manual register! call needed.
