File Complexity*
The distribution of files by complexity: the sum of the McCabe indexes of their units.
File Complexity Overall
  • There are 20 files with units, with 8,385 lines of code.
    • 3 very complex files (McCabe index sum 251+; 4,799 lines of code)
    • 3 complex files (McCabe index sum 126-250; 2,005 lines of code)
    • 3 medium complex files (McCabe index sum 51-125; 818 lines of code)
    • 2 slightly complex files (McCabe index sum 26-50; 384 lines of code)
    • 9 simple files (McCabe index sum 1-25; 379 lines of code)
  • 2 main files have no units (e.g. languages without unit analysis, or files without functions) and are not classified.

Most Complex Files (Top 20)

The McCabe index of a file grows with its size: per 100 lines tells a large but plain file from a dense one, and most complex unit whether the complexity sits in one unit or is spread over many.

About This Analysis
  • File complexity is the sum of the McCabe indexes (conditional complexity) of the units (methods, functions...) in a file.
  • Files are classified in five categories based on that sum: 1-25 (simple files), 26-50 (slightly complex files), 51-125 (medium complex files), 126-250 (complex files), 251+ (very complex files). The default bands are five times the unit complexity bands, as a file is a group of units.
  • Only main code files with units are classified. Files without units (languages without unit analysis, or files without functions) have no complexity to measure and are left out rather than counted as simple.
  • A very complex file holds many decisions, which often means it has too many responsibilities: a candidate to split, and a place where changes need more testing.
