Function Length Inspector

Description & Learning Section

Keeping functions small and focused improves readability, testability, and maintainability. Large functions often violate the “single responsibility” principle and become hard to debug.

Metrics Explained:

• Total Lines: Every line from definition to end, including blank and comment lines.
• Code Lines: Non‑blank, non‑comment lines—your actual executable code.
• Comment Lines: Lines starting with #, //, or /*.
• Blank Lines: For readability separation, not counted as code.

Threshold & Sorting:

• Flag functions exceeding your code or total‑line threshold.
• Sort the list by either metric to quickly find the largest offenders.

Statistics & Histograms:

• See min/max/average/median for both total and code lines.
• Visualize distribution with a simple “*”‑based histogram (1 * per 5 lines).

Example:

def example(a, b):
    # Initialize
    result = a + b

    if result > 10:
        # deep logic
        for i in range(result):
            print(i)
    else:
        print("small")

    return result
    

- Total Lines: 10
- Code Lines: 6 (every executable statement)
- Comment Lines: 2
- Blank Lines: 2
