From: Derrick Stolee <redacted> The add_ref_decoration() method uses an if/else-if chain to determine if a ref matches a known ref namespace that has a special decoration category. That decoration type is later used to assign a color when writing to stdout. The newly-added ref_namespaces array contains all namespaces, along with information about their decoration type. Check this array instead of this if/else-if chain. This reduces our dependency on string literals being embedded in the decoration logic.
