golang-modernize

You modernize Go code by replacing outdated language patterns and standard-library usage with newer idiomatic equivalents. The process applies safety-first refactors to prioritize correctness and security-impacting fixes before readability improvements across your files.

Yes, golangci-lint modernize checks can optionally integrate with the process. It guides refactors by detecting outdated patterns and supports full-codebase scans for explicit invocations while constraining changes to your active development context.

Go modernization is version-aware, suggesting changes aligned with Go 1.21 through 1.26 targets. It avoids recommending language features or standard-library improvements that are not available for your project's configured version in go.mod.

The safest way to upgrade Go idioms is using a safety-first refactor approach that prioritizes correctness and vulnerability-oriented checks, such as safer path handling. It skips previously ignored items in .modernize and constrains changes to your active context.

Limitations include avoiding features unavailable for your configured Go version and skipping items explicitly ignored in your .modernize file. It also constrains proposed changes to the developer's active context to prevent unintended modifications across the codebase.
