Modernize old Go idioms with a reviewable go fix diff

Go 1.26 rebuilt go fix around analyzers that recognize outdated code patterns and replace them with newer language or library features. Examples include simpler min/max expressions, range-over-integer loops and strings.Cut. Developers can preview the patch, select individual fixes and review the changes separately from feature work, while generated files are left alone.

Why it matters

A useful way to learn modern Go idioms while reducing repetitive migration work.

More context

This February guide covers released tooling. Try go fix -diff on a clean checkout before applying changes, then review and run your project’s tests. Fixers respect the minimum Go version declared for a file.

Keep in mind

A run covers one build configuration; platform-specific files may need separate checks. Automated rewrites still need review, and 1min has not run them on your code.
