Function extractStringSlice

scripts/metricsdocgen/scanner/scanner.go:312–320

extractStringSlice extracts a []string from a composite literal. Example: - []string{"a", "b", myConst}: ["a", "b", ]

(lit *ast.CompositeLit, decls declarations)

// Example:
//   - []string{"a", "b", myConst}: ["a", "b", <resolved value of myConst>]
func extractStringSlice(lit *ast.CompositeLit, decls declarations) []string {
	var labels []string
	for _, elt := range lit.Elts {
		if label := resolveStringExpr(elt, decls); label != "" {
			labels = append(labels, label)
		}
	}
	return labels
}

// collectDecls collects const and var declarations from a file.
// This is used to resolve constant and variable references in metric definitions.
