wmc_metric

Weighted Methods per Class (WMC) metric. Uses unit weights, i.e., the score is the number of locally defined (non-auxiliary) predicates. Protocols are not scored as they cannot define predicates. The score is represented by a non-negative integer.

Remarks:

• Unit weights: Each predicate is assigned a weight of 1. A cyclomatic-complexity-weighted variant is not provided as the Logtalk reflection API does not expose intra-clause branching structure (if-then-else, disjunction), which would produce the same approximations as the cc_metric.

• Interpretation: Higher scores indicate an entity with more responsibilities that may benefit from being split.

• Aggregation: When computing scores for files, directories, and libraries, the individual entity scores are summed.
