Unit Size

The distribution of size of units (measured in lines of code).

Intro
  • Unit size measurements show the distribution of size of units of code (methods, functions...).
  • Units are classified in four categories based on their size (lines of code): 1-20 (small units), 20-50 (medium size units), 51-100 (long units), 101+ (very long units).
  • You should aim at keeping units small (< 20 lines). Long units may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

Unit Size Overall
  • There are 4,383 units with 32,724 lines of code in units (44.7% of code).
    • 13 very long units (1,942 lines of code)
    • 34 long units (2,196 lines of code)
    • 248 medium size units (7,715 lines of code)
    • 477 small units (6,908 lines of code)
    • 3,611 very small units (13,963 lines of code)
