Real-time complexity metrics for Smalltalk methods

摘要

This paper presents the rationale for ubiquitous and immediate metric feedback on the complexity of Smalltalk methods whenever they are viewed or changed. It also presents seven metrics for Smalltalk methods that can be quickly and easily determined from the code and are suitable for real-time feedback. For each of these metrics, there is a description, an explanation of how it is determined and why it is related to complexity, and suggestions for how to improve code that receives a poor rating for the metric.
