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
