Analysis and Transformation Tools for Go Codebase Modernization
summary
Reports progress on the Go analysis framework used by cmd/vet and gopls, shows a suite of 20 modernizers that suggest-and-fix small API and idiom upgrades, and describes a source-level inliner (about 7,000 lines) that safely rewrites calls annotated with a gofix inline comment. Experiments find LLMs ignore new features across ~20 cases, many handcrafted modernizers contain subtle bugs, and the inliner proves reliable enough for mass automated fixes when integrated into go fix/go tools.
