🌳 Gomplekity

Overview

Gomplekity analyzes the cyclomatic complexity of your Go code and generates a beautiful tree visualization.

The leaf colors represent different complexity levels, and the color distribution reflects the proportion of functions at each complexity level.

Not a serious tool. A simple Go complexity visualizer that turns your code complexity into a tree with colored leaves.

• 🟢 Green: Low complexity (0-9)
• 🟡 Yellow: Medium complexity (10-14)
• 🔴 Red: High complexity (15-19)
• 🟤 Brown: Critical complexity (20+)

Installation

go install github.com/masakurapa/gomplekity@latest

Usage

Basic usage

# Analyze current directory (outputs PNG by default)
gomplekity

# Analyze specific directory
gomplekity -dir ./src

# Custom output file
gomplekity -output my_project.png

# Generate SVG instead of PNG
gomplekity -output my_project.svg -svg

Advanced options

# Show detailed analysis
gomplekity -verbose

# Custom complexity thresholds
gomplekity -medium 8 -high 12 -critical 16

# All options with PNG output
gomplekity -dir ./src -output project.png -medium 8 -high 12 -critical 16 -verbose

# All options with SVG output
gomplekity -dir ./src -output project.svg -svg -medium 8 -high 12 -critical 16 -verbose

Options

-dir string         Directory to analyze (default ".")
-output string      Output file path (default "complexity_tree.png")
-medium int         Medium complexity threshold (default 10)
-high int           High complexity threshold (default 15)
-critical int       Critical complexity threshold (default 20)
-verbose            Show detailed complexity analysis
-svg                Generate SVG output instead of PNG
-help               Show help message

Name Origin

"Gomplekity" combines:

• Go - The Go programming language
• Complexity - Code complexity
• 木 (ki) - Japanese word for "tree"

But it might help you understand your code complexity in a fun way! 🌳✨
