GoCity is an implementation of the Code City metaphor for visualizing source code. GoCity represents a Go program as a city, as follows:

• Folders are districts
• Files are buildings
• Structs are represented as buildings on the top of their files.

Structures Characteristics

• The Number of Lines of Source Code (LOC) represents the build color (high values makes the building dark)
• The Number of Variables (NOV) correlates to the building's base size.
• The Number of methods (NOM) correlates to the building height.

Installation

• go install github.com/rodrigo-brito/gocity@latest
• Or just head to the releases page and download the latest version for you platform.

Usage:

• Online: https://go-city.github.io
• Commands
  • gocity server - Start server
  • gocity open <GITHUB_IMPORT> - Open a specific Github project from github
  • gocity open ./my-project - Open a local directory

UI / Front-end

The UI is built with React and uses babylon.js to plot 3D structures. The front-end source code is available in the front-end branch.
