Sourcery Analytics

sourcery-analytics is a command line tool and library for statically analyzing Python code quality.

Get started by installing using pip:

pip install sourcery-analytics

This will install sourcery-analytics as a command-line tool.

To identify code quality issues:

sourcery-analytics assess path/to/file.py

Example:

sourcery-analytics assess sourcery_analytics/metrics

sourcery_analytics/metrics/cyclomatic_complexity.py:47: error: working_memory of cyclomatic_complexity is 34 exceeding threshold of 20
Found 1 errors.

To analyze a single Python file, use the analyze subcommand:

sourcery-analytics analyze path/to/file.py

Example:

sourcery-analytics analyze sourcery_analytics/analysis.py

Alternatively, import and run analysis using the library:

from sourcery_analytics import analyze_methods
source = """
    def cast_spell(self, spell):
        if self.power < spell.power:
            raise InsufficientPower
        print(f"{self.name} cast {spell.name}!")
"""
analyze_methods(source)
# [{'method_qualname': '.cast_spell', 'method_length': 3, 'method_cyclomatic_complexity': 1, 'method_cognitive_complexity': 1, 'method_working_memory': 6}]
