Complexipy VSCode Extension

A Visual Studio Code extension that provides real-time cognitive complexity analysis for Python code. This extension helps developers identify and manage code complexity by providing visual indicators for both function-level and line-level complexity.

Features

• Real-time Complexity Analysis: Automatically analyzes Python code as you type
• Visual Complexity Indicators:
  • Function complexity shown with ƒ symbol
  • Line-level complexity shown with + symbol
  • Color-coded indicators:
    • Green: Low complexity (functions < 15, lines ≤ 5)
    • Red: High complexity (functions ≥ 15, lines > 5)
• Automatic Updates: Complexity analysis updates on:
  • File save
  • Active editor change
  • Text changes

Requirements

• Visual Studio Code version 1.85.0 or higher
• Python files to analyze

Installation

1. Open VS Code
2. Go to the Extensions view (Ctrl+Shift+X / Cmd+Shift+X)
3. Search for "complexipy"
4. Click Install

Usage

The extension automatically activates when you open a Python file. You'll see complexity indicators appear at the end of each line:

• ƒ N: Function complexity score (where N is the complexity value)
• +N: Line-level complexity score (where N is the complexity value)

Manual Analysis

You can trigger a manual analysis by:

1. Opening the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
2. Typing "complexipy"
3. Selecting the "complexipy" command

Complexity Thresholds

• Function Complexity:

  • Low: < 15
  • High: ≥ 15

• Line Complexity:

  • Low: ≤ 5
  • High: > 5
