gofumpt is a stricter, backwards-compatible fork of gofmt that formats Go source code with additional idiomatic style rules. It works as a drop-in replacement for gofmt and is also usable as a Go library via its format package.

Use cases

  • format go code with stricter rules than gofmt
  • enforce idiomatic go style across a codebase
  • drop-in replacement for gofmt in ci
  • automatically clean up empty lines and formatting in go files
  • consistent code formatting independent of go version

When to choose

  • you want stricter, more idiomatic formatting than gofmt while staying gofmt-compatible
  • you need deterministic formatting regardless of the installed Go toolchain version
  • you want a formatter that skips vendor, testdata, and generated files by default

When to avoid

  • you prefer standard gofmt output exactly as shipped with Go
  • you need gofmt's -r rewrite flag, which gofumpt removed
  • your team cannot agree on the extra opinionated rules
