Flake8 Code Quality Issues in Visual Script

Unused Import Cleanup

  • Remove unnecessary imports in multiple files:

### commands/base.py - Line 5: Unused imports 

# Remove or comment out unused imports
# from typing import Dict, List, TypeVar

### docs/build.py - Line 3: Unused sys import - Line 5: Unused typing.List import - Line 72-73: Unused MkDocs config imports 

# Remove or comment out
# import sys
# from typing import List
# from mkdocs.config.base import Config
# from mkdocs.config.defaults import MkDocsConfig

### docs/visual.py - Line 5: Unused sys import - Line 8: Unused type-related imports - Line 19: Unused TypeGuard - Line 21: Unused Page - Line 25-27: Unused Playwright imports 

# Remove or comment out
# import sys
# from typing import Union, Protocol, runtime_checkable
# from typing_extensions import TypeGuard
# from playwright.async_api import Page
# import playwright
# from playwright.sync_api import (
#     TimeoutError as PlaywrightTimeoutError,
#     Error as PlaywrightError
# )

Line Length Refactoring

Specific Files and Lines to Fix

  • core/command.py

  • Line 31: Exceeds 79 characters

  • docs/build.py

  • Line 72: 86 characters (exceeds limit)

  • Line 92: 86 characters (exceeds limit)

  • docs/setup.py

  • Line 30: 81 characters (exceeds limit)

  • docs/visual.py

  • Line 84: 111 characters
  • Line 181: 91 characters
  • Line 186: 82 characters
  • Line 360: 94 characters
  • Line 467: 92 characters
  • Line 560: 86 characters
  • For each identified long line:
  • Break into multiple lines
  • Use line continuation \ or parentheses ()
  • Extract complex logic into separate methods
  • Use f-string formatting for readability

Code Example for Line Length Reduction

# Before (bad)
complex_long_method_with_many_parameters_and_very_long_signature(param1, param2, param3)

# After (improved)
complex_long_method_with_many_parameters_and_very_long_signature(
    param1, 
    param2, 
    param3
)

Import Management Strategy

  • Create a systematic approach to import management
  • Group imports: standard library, third-party, local
  • Remove unused imports during code review
  • Use isort to automatically organize imports
  • Consider using # noqa comments for intentionally unused imports

  • Install and configure: 

    pip install flake8 isort black

  • Create .flake8 configuration 

    [flake8]
max-line-length = 79
extend-ignore = E203, W503
exclude = 
    .git,
    __pycache__,
    build,
    dist

Continuous Improvement

  • Set up pre-commit hooks to run linters automatically
  • Integrate linting into CI/CD pipeline
  • Regularly review and refactor code for readability

Next Steps

  • Apply these fixes systematically
  • Run flake8 to verify improvements
  • Commit and review changes
  • Update project documentation

Additional Recommendations

  • Prefer explicit type hints
  • Keep functions and methods concise
  • Use meaningful variable names
  • Break complex logic into smaller, more readable functions
