Rubber Duck Thursdays - GitHub Skyline
In this inaugural Rubber Duck Thursdays episode, Chris introduces GitHub Skyline — a GitHub CLI extension written in Go that generates 3D STL models and ASCII art visualizations of your GitHub contribution history. The stream demonstrates the gh skyline command, including the --full flag for rendering your entire contribution history across all years as a single 3D model suitable for 3D printing.
The main coding activity focuses on refactoring the Skyline Go codebase using GitHub Copilot. Chris uses Copilot Chat for rubber ducking on code structure, then leverages Copilot Edits to split a monolithic main.go into modular components — separating the root command, browser interface, GitHub client, and skyline generation logic into individual files. The stream also covers GitHub Codespaces and dev containers for setting up a consistent development environment, and discusses community files like CODE_OF_CONDUCT, CONTRIBUTING, and LICENSE for open source projects.
