Code Complexity

Analyzes code complexity and provides metrics

LLA Code Complexity Plugin

Analyze code complexity with live metrics.

Features

  • Multiple metrics: cyclomatic, cognitive, maintainability index
  • Function/class summaries
  • Thresholds with colors
  • Live stats and detailed reports

Default Configuration

Complexity Thresholds

  • Low: < 10.0
  • Medium: < 20.0
  • High: < 30.0
  • Very High: ≥ 40.0

Language Support (Default: Rust)

  • Function: fn
  • Class: struct, impl, trait
  • Branch: if, match, else
  • Loop: for, while, loop
  • Comments: //, /*
  • Max Line Length: 100
  • Max Function Length: 50 lines

Usage

# Set complexity thresholds
lla plugin --name code_complexity --action set-thresholds --args 10 20 30 40
 
# Show report
lla plugin --name code_complexity --action show-report
