Case study

Toolset

A toolset that would:parse source code automatically (~2800

modules, ~1.7 MLOCs)calculate quality metrics and produce

inputs for visualisation toolsallow the user to reproduce the entire

cycle (e.g. after new release)be reusable for other code analysis

projects, other languages
