semantic-complexity (Python)

Multi-dimensional code complexity analyzer for Python.

Installation

pip install semantic-complexity

Usage

CLI

# Analyze a file
semantic-complexity path/to/file.py

# Analyze a directory
semantic-complexity path/to/project/

# Output as Markdown report
semantic-complexity path/to/project/ -f markdown -o report.md

# Filter by threshold
semantic-complexity path/to/project/ --threshold 20

Python API

from semantic_complexity import analyze_source, analyze_functions

# Analyze source code
result = analyze_source("""
def complex_function(x):
    if x > 0:
        for i in range(x):
            if i % 2 == 0:
                print(i)
""")

print(f"Weighted complexity: {result.weighted}")
print(f"Control (1D): {result.control}")
print(f"Nesting (2D): {result.nesting}")
print(f"Contributions: {result.contributions}")

# Analyze functions individually
functions = analyze_functions(source)
for fn in functions:
    print(f"{fn.name}: McCabe={fn.cyclomatic}, Dimensional={fn.dimensional.weighted}")

Dimensions

Dimension	Weight	Description
1D Control	1.0	Cyclomatic complexity (branches, loops)
2D Nesting	1.5	Depth penalty
3D State	2.0	State mutations and transitions
4D Async	2.5	Async/await, coroutines
5D Coupling	3.0	Hidden dependencies, side effects
