Taking Back the Command Line with Go
summary
Claims that Go replaces Ruby for CLIs with rewrote the Cloud Foundry CLI from Ruby to Go, showing the actual code patterns used: interfaces for terminal and repositories, dependency injection, and structs for return values. Demonstrates a weekend exorcism rewrite and a repo that grows to ~1,800 commits. Delivers cross-compile dependency-free statically linked binaries so each platform gets one binary per platform, and reports that the approach works in production while reducing runtime-dependency problems.
