Rubber Duck Thursdays - Rock, Paper, Scissors
In this episode, I add a Rock Paper Scissors game to the gh-game GitHub CLI extension. The stream begins with a comprehensive GitHub changelog review covering the new GPT-4o Copilot code completion model, Copilot availability in Eclipse and Xcode, repository ruleset enhancements, secret scanning improvements, Copilot Workspace updates, and GitHub Issues and Projects feature updates.
The coding session uses GitHub Copilot Agent Mode to build the Rock Paper Scissors game in Go, taking advantage of Next Edit Suggestions and the new GPT-4o code completion model. A significant portion of the stream focuses on improving test coverage using Copilot’s inline chat in the terminal, progressing from 42.6% to 100% statement coverage by generating targeted test cases for uncovered functions. The episode also covers merging the Tic Tac Toe pull request from the previous week and shipping a new release of the CLI extension.
