Write Less (Code), Generate More
summary
Argues that Go code generation reduces repeated boilerplate by example: builds a simple generator that uses go/packages and AST/type info to find all constants of a named integer type and emits a formatted String() method into a gen_ file via a text template and gofmt. Integrates generation into workflow with go generate and a go-generate wrapper that adds an artifact cache and dependency-aware ordering. The generator works but omits edge cases and optimizations.
