+# go-detect-race
+
+Check if the race detector is running.
+
+I didnt find a variable to check quickly enough so I made this.
+
+
+## Usage
+
+```go
+import (
+  detectrace "github.com/jbenet/go-detect-race"
+)
+
+func main() {
+  if detectrace.WithRace() {
+    // running with -race
+  } else {
+    // running without -race
+  }
+}
+```

race.go

+package detectrace
+
+// WithRace returns whether the binary was compiled
+// with the race flag on.
+func WithRace() bool {
+	return withRace
+}

race_test.go

+package detectrace
+
+import (
+	"testing"
+)
+
+func TestWithRace(t *testing.T) {
+	t.Logf("WithRace() is %v\n", WithRace())
+}

withoutrace.go

+// +build !race
+
+package detectrace
+
+const withRace = false

withrace.go

+// +build race
+
+package detectrace
+
+const withRace = true
