Method LoadMatchingRules

cli/workspace/rules.go:45–82

LoadMatchingRules returns all rules that match the given file paths. If contextPaths is empty, returns only global rules (no paths: filter). Rules from workspace override global rules with the same name.

(contextPaths []string)

// If contextPaths is empty, returns only global rules (no paths: filter).
// Rules from workspace override global rules with the same name.
