pyward-cli 0.1.7

A CLI linter for Python that flags optimization and security issues

PyWard

PyWard is a lightweight command-line linter for Python code. It helps developers catch optimization issues (like unused imports and unreachable code) and security vulnerabilities (such as unsafe eval/exec usage and known CVE patterns).

Features

• Optimization Checks

  • Detects unused imports
  • Flags unreachable code blocks

• Security Checks

  • Flags usage of eval() and exec() (e.g., CVE-2025-3248)
  • Detects vulnerable imports like python_json_logger (e.g., CVE-2025-27607)

• Flexible CLI

  • Run all checks by default
  • Use -o/--optimize to run only optimization checks
  • Use -s/--security to run only security checks
  • Use -v/--verbose for detailed output, even if no issues are found

Installation

Install from PyPI:

pip install pyward-cli

Ensure that you have Python 3.7 or newer.

Usage

Basic usage (runs both optimization and security checks):

pyward <your_python_file.py>

Options

• -o, --optimize
  Run only optimization checks (unused imports, unreachable code).

• -s, --security
  Run only security checks (unsafe calls, CVE-based rules).

• -v, --verbose
  Show detailed warnings and suggestions, even if no issues are detected.

Examples

Run all checks on demo.py:

pyward demo.py

Run only optimization checks:

pyward -o demo.py

Run only security checks:

pyward -s demo.py

Run with verbose mode:

pyward -v demo.py
